This submission supplements NHTSA Complaint #11759206, filed on August 24, 2026, regarding a 2018 Volvo XC90, in order to provide additional relevant information that came to light after the original filing. At the time of the first safety-critical malfunction (in-vehicle warnings including "Transmission Acceleration Performance Reduced" "Gear Lever Locked" and related electrical system symptoms), the service manager at Volvo Cars Brooklyn was able to remotely diagnose the likely cause by telephone, before the vehicle was even towed to the shop, specifically instructing the owner to check for dampness under the driver's floor mat, which was confirmed to be present. This indicates the symptom pattern described (sunroof leak leading to corrosion affecting the transmission, brakes, and electrical system) was already recognized and familiar to Volvo Cars Brooklyn's service staff, not a novel or difficult-to-diagnose issue. Additionally, the owner was informed that multiple other Volvo vehicles were present at Volvo Cars Brooklyn on the same day for repair of the same reported issue. Once arriving at the dealership, the service manager tole us that he had, "Just totaled a vehicle for the same issue." This suggests the underlying defect is not an isolated occurrence, but a broader, recurring pattern affecting multiple vehicles of this platform. This supplemental information is provided to support NHTSA's assessment of whether a safety-related defect trend exists affecting this vehicle platform, consistent with the pattern described in the original complaint and in other publicly available consumer complaints regarding sunroof-related water intrusion on the Volvo XC90.
NHTSA complaint #11759327 — an unverified report by a vehicle owner.
The vehicle first experienced a safety-critical malfunction while driving on the highway on August 11, 2026, producing in-vehicle warnings reading "Transmission Acceleration Performance Reduced" and "Gear Lever Locked," along with broader electrical system symptoms, requiring the 2018 Volvo XC90 to be towed to Volvo Cars Brooklyn on August 11, 2026. At that time, dampness was discovered under the driver’s floor mat, leading to the discovery of a sunroof leak and resulting water intrusion. The dealership represented the vehicle as fully repaired and safe to drive. The same safety-critical malfunction occurred later that night, while driving about 90 miles away from the dealership, with the same warnings appearing, confirming that the original repair failed to address the underlying issue. Loss of normal transmission and braking function while the vehicle was in motion directly affected the driver's ability to control the vehicle. The vehicle was towed for a second time on the morning of August 12, 2026, to Volvo Cars Brooklyn, where it was confirmed that module corrosion caused by the original sunroof leak had not been properly diagnosed or corrected during the first service visit, and that this corrosion had disrupted signals to the vehicle’s electrical, braking, and transmission systems. The dealership completed a corrective repair on August 12, 2026, replacing the OFM module and removing water, following the second incident. The vehicle has not been separately inspected by Volvo’s manufacturer-level engineering team. This failure is consistent with a broader, documented pattern affecting this vehicle platform. Volvo has previously issued a Technical Service Bulletin addressing a sunroof-related water leak on an earlier model year of this platform. While that bulletin does not specifically cover the 2018 model year, numerous 2018 model year owners have independently reported the same failure pattern, a failed sunroof seal, often linked to clogged sunroof drains.
NHTSA complaint #11759206 — an unverified report by a vehicle owner.
In February 2026, my 2021 Volvo XC90 Recharge T8 (VIN: [XXX]) experienced a hybrid battery cell failure. The failure was diagnosed and confirmed by an authorized Volvo dealership (Volvo of Tacoma) and is covered under the vehicle's manufacturer warranty. However, I have been informed that a replacement part may not be available until December 2026 or later — a delay of ten months or more from the original failure date. Volvo has advised me that attempting to charge the vehicle in its current state carries a risk of fire. As a result, I am unable to charge the hybrid system and have had to operate the vehicle on gasoline alone, with fuel costs increasing approximately 3.5x per month. Separately, an independent mechanic has advised me that continued operation of the vehicle without a functioning hybrid battery cell is causing ongoing, worsening mechanical damage over time, separate from the original defect. I have made extensive good-faith efforts to resolve this directly with Volvo Cars USA customer care, including phone calls, an online request form, and direct correspondence, with prolonged periods of no response despite written acknowledgment of the issue on XXX. Given that Volvo itself has identified a fire risk associated with charging this vehicle, combined with an indefinite repair timeline of ten months or more and mechanic-confirmed risk of continued mechanical degradation, I am filing this report to document a potential safety defect in the hybrid battery system of this vehicle.

At first I was having issues with stop and start, replaced the battery then was told I wasted coffee in my center Console and it cause electrical issues and was told the repairs would be 3,400 in which collision issuance paid for. After the repairs my driver side seat belt would latch then the passenger side wouldn’t latch either so I currently don’t have working A/C or working seatbelts which is known problem for these vehicles.

NHTSA complaint #11756005 — an unverified report by a vehicle owner.
My 2024 Volvo XC90 has experienced complete battery and electrical failure three times in approximately ten months. The failure pattern is identical each time. The battery discharges fully with no prior warning. A jump start restores power briefly, but the vehicle does not hold a charge and shuts down again, so it must be towed. The battery has been replaced three separate times by authorized Volvo retailers and the failure keeps recurring, which indicates the underlying cause has not been identified. Component: Electrical system, specifically a suspected parasitic current draw causing complete discharge of the 12V battery. The vehicle is available for inspection on request. Safety risk: The vehicle becomes completely inoperable without warning and has stranded me three times, requiring towing on each occasion. There is no advance indication that the battery is failing. Because the failure is sudden and unpredictable, the vehicle cannot be relied on to start in an emergency or to remain operable, and I have no confidence that a failure will not occur at a time or place that puts occupants at risk. Confirmed by dealer: Yes. Each failure was confirmed by an authorized Volvo dealer, which replaced the battery each time. Repairing dealers include Independence Volvo and University Volvo. The failures occurred in approximately October 2025, approximately March or April 2026, and [date of current failure]. The vehicle is currently at [dealer] for the third occurrence. Inspection by manufacturer or others: Volvo Car USA corporate has not inspected the vehicle. No police or insurance inspection. To my knowledge no dealer has performed or documented a parasitic draw test to locate the source of the discharge. Warning lamps or symptoms: None. There were no warning lamps, dashboard messages, or symptoms of any kind before any of the three failures. The vehicle operated normally and then would not start. Total days out of service: at least 15 days across the three times

The contact owns a 2025 Volvo XC90. The contact stated that while driving at an undisclosed speed, the safety alert audible sounds failed to function as intended. The contact stated that the alerts failed to provide an audible alert. The contact turned off the vehicle and started and the system independently reset. The vehicle was taken to the dealer, and an unknown software update was performed. The vehicle was repaired; however, the failure reoccurred. The failure became persistent. The contact stated that while reversing, the rear-view camera screen seized. The contact stated that the rear-view camera displayed a still image. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 4,500.
NHTSA complaint #11753962 — an unverified report by a vehicle owner.
My 2020 Volvo XC90 T8 plug-in hybrid has been out of service for 78+ days due to a hybrid battery defect covered under an active manufacturer warranty (Claim Type XXX, valid through XXX). The vehicle was towed to Volvo Cars Arrowhead (Glendale, AZ) on XXX after a hybrid battery failure. The dealer confirmed in writing on XXX that multiple hybrid components require replacement and that parts are on extended backorder, and that Volvo Cars USA had authorized a rental vehicle because a loaner could not be offered "for an indefinite period of time." On approximately XXX, my service advisor advised me by phone that more than 700 vehicles nationally are waiting on the same backordered part and that the repair has no estimated completion date. I sent a formal written demand to Volvo Car USA ([XXX]) on XXX requesting repair by a firm date, a replacement vehicle, or repurchase. Volvo did not respond within the stated 14-day deadline or at any point thereafter. The defect appears related to NHTSA's existing recall action on 2020–2022 Volvo plug-in hybrid vehicles for high-voltage battery thermal runaway risk. I am filing this complaint to add to the federal record on this recall and to document Volvo's failure to repair an affected vehicle within a reasonable time or provide any remedy despite formal demand.

NHTSA complaint #11752094 — an unverified report by a vehicle owner.
I am reporting a serious safety concern involving a 2018 Volvo XC90 T8 PHEV. On [XXX], at approximately [XXX] CT, the vehicle experienced a sudden multi-system safety and actual brake failure while in a parking-lot/low-speed setting near [XXX} in Austin, Texas. The vehicle displayed multiple urgent warning messages and indicators, including power steering failure / stop safely, brake/ABS warning, SRS airbag service urgent warning, stability/traction warning, battery/electrical warning, check-engine warning, and tire-pressure warning. The vehicle ended in an irregular/distressed parking position after trying to locate a concrete block to force stop the car due to ABSOLUTE BRAKE FAILURE, E BRAKE SEEMED TO NOT WORK EITHER. The concern is not simply that a warning light appeared. The event involved steering, braking, airbag/SRS, stability, and electrical warnings at the same time, making the vehicle unsafe to operate AND SOMEHOW THE BRAKES WEREN’T OPERATING DUE TO THE LACK OF FUNCITONING. Photos were taken of the warning messages and vehicle position. Prior related history: This vehicle has prior safety-system history involving SRS Airbag Service Urgent warnings and braking/vehicle malfunction and movement concerns. Earlier review and discussion involved Volvo engineering, VDDM replacement, CAN/network concerns, calibration requirements, voltage/12V battery considerations, software/module updates, and post-repair validation. The VDDM is understood to participate in vehicle dynamics, stability control, brake coordination, and PHEV regenerative/hydraulic brake interaction. Prior documentation also raised concern that intermittent brake, SRS, VDDM, CAN, and calibration issues may not reproduce during a short dealer test drive. Safety risk: The safety risk is that the vehicle may experience sudden or intermittent loss, degradation, or warning of systems involved in steering, braking, stability control, and airbag readiness.

NHTSA complaint #11746058 — an unverified report by a vehicle owner.
My 2018 Volvo XC90 T8 Plug-In Hybrid experienced a catastrophic, premature component failure of the Electric Rear Axle Drive (ERAD) propulsion system while driving. The ERAD unit suffered a total failure of internal bearings and sensors, completely disabling the electric rear wheel propulsion system and suddenly forcing the vehicle into a reduced-power "limp mode" on the road. This sudden loss of hybrid propulsion creates an immediate highway safety hazard, removing expected acceleration and vehicle control in traffic. Volvo has documented this exact engineering flaw internally under Technical Journal TJ 36665, recognizing a manufacturing vulnerability in these specific hybrid components. However, the manufacturer is refusing to provide remedy or financial cost-sharing to repair this vital propulsion and safety defect, leaving a hazardous, compromised vehicle on the road.

The Infotainment Head Unit (IHU) on my 2024 Volvo XC90 has experienced repeated total system blackouts, spontaneous power-cycles, and critical thermal failures while operating at highway speeds (46–77 MPH). The IHU displays a "Cooling Infotainment System" critical warning and fails completely, resulting in total loss of the federally mandated rearview/backup camera (FMVSS 111 violation), GPS navigation, and all safety interfaces while in motion. The dealer confirmed the defect and attempted repair twice but only performed software resets rather than hardware replacement. The dealer documented "FIXED FAILED." Failures have continued and worsened after both repair attempts. Video documentation exists for all incidents (Exhibits A–H, dated May 2–7, 2026, odometer 41,900–42,151 miles). The vehicle's own diagnostic system issued a Critical Thermal Warning on the driver cluster while navigating traffic, confirming a hardware cooling defect. Two failures occurred during active driving maneuvers including a reverse maneuver and highway operation on I-20, creating immediate safety risk to the driver and public. The component is available for inspection. The defect has been confirmed by the Volvo dealer. A Texas Lemon Law complaint has been filed.
NHTSA complaint #11736880 — an unverified report by a vehicle owner.
The suspension module failed due to water accumulation on floorboards. Suspect other electronics may be at risk. Water ingress cause by a combination of what dealer said was a worn out sunroof gasket and two of four drains that became plugged. Further examination from dealer found the plugged drains were crimped from when the vehicle was manufactured. The dealer blamed the excessive water ingress was further allowed by a failed sunroof seal. The vehicle has always been serviced by the dealer and problem areas like that were either not inspected or not reported. The seal appears as good as the day we purchased vehicle from dealer. It seems it needs a more expert eye to detect how it fails. The result was standing water in the floor boards and body cavities, which then caused the suspension module to fail. The entire interior had to be disassembled to verify there was no further electrical damage. The dashboard and other interior pieces needed to be removed to replace or correct the drains. This appears to be a common problem with this model although no service advisories seem to have been issued. Total estimated damage is about $5200. Vehicle has only 60K miles. Volvo has rejected responsibility for the compromised drain and failed sunroof seal. Service documentation attached, not including the estimated $1700 to remove dash for repairs.

Driving on highway. Selected another route on map, but the screen lagged in response. Screen then went dark, shut off electronics on dashboard and infotainment, and AC turned off; seems like car also slowed down. Able to pull over and wait for everything to restart. Safety put at risk: sudden change in environment causing attention to shift to safely getting off road incase car shut off entirely. Previously: Infotainment has been off at start-up before; never had this problem while driving, though. One incident in drive-thru where I pressed infotainment and whole car shut off. Vehicle has been taken to dealership services for annual and as needed, codes have been ran extensively, and no faults have been found. The concerning incident occurred an hour ago so I have not brought to dealership yet, but seeing online that the problem is not just with my vehicle.

To whom it may concern. Our 2017 XC90 unexpectedly, spantaneously, and catastrophically caught fire under the hood and was a total loss 5 minutes after parking it on April 19, 2026. There were no leaks or other signs of mechanical issues. The vehicle had all regular maintenance completed at the Byers Volvo Service Department in Columbus, OH. It had no open recalls. It was always parked overnight in a garage. The Fire Inspector noted a possible vehicle manufacturing defect as the cause of the fire, however the vehicle was too heavily damaged to be definitive. We do have video of the entire incident as the Volvo was parked on Federal Government Property at the time. We are happy to share any and all information if this helps future vehicles to be safer. It should be noted that there is an active recall for the 2016 XC90 for a coolant hose leak that can cause a fire. Given that the 2017 XC90 is of the same design. Upon checking the internet and Reddit, it appears that our situation is not unique and there are other instances and reports of similar fires.

SUPPLEMENTAL TO NHTSA COMPLAINT #11713668. This is a supplemental filing regarding the 2020 Volvo XC90 T8 Inscription, VIN [XXX] . The hybrid battery cell module failed in December 2025, disabling the vehicle's hybrid propulsion system, all-wheel drive, and electric-only mode. As of this filing, the vehicle has been without hybrid functionality for over four months. The replacement part remains unavailable. Since the original complaint, the owner initiated civil proceedings against Volvo Car USA LLC and Volvo Car North America LLC in the State Court of Gwinnett County, Georgia (Case No. [XXX]). Through that litigation, the following facts have been established as deemed admissions under Georgia law, which neither Defendant contested: 1.This vehicle is excluded from Recall 25V-179, yet experienced a catastrophic hybrid battery cell module failure. 2.Battery failures in 2019-2022 XC90 T8 vehicles are not exclusively caused by the "LG supplier process deviation" identified in Recall 25V-179. 3.Volvo is aware of battery failures in 2019-2022 XC90 T8 vehicles outside the Recall 25V-179 population. 4.Volvo possesses internal engineering data showing the battery defect affects vehicles outside the population reported to NHTSA in Recall 25V-179. 5.Volvo has not issued a recall for the specific failure mode affecting this vehicle. 6.Expanding Recall 25V-179 to cover the full 2019-2022 XC90 T8 population would cost Volvo tens of millions of dollars. These facts were established against both Volvo entities through separate sets of Requests for Admission that went unanswered within the statutory deadline. The owner requests that NHTSA evaluate whether Recall 25V-179 is adequate to protect the full population of affected vehicles. Supporting documentation, including copies of the deemed admissions and service records, is being submitted by mail to the Office of Defect Investigation.

NHTSA complaint #11733717 — an unverified report by a vehicle owner.
A software update (version 5.0.5) was complete on my 2024 Volvo XC90 at the end of March. The software was marketed in emails to have an enhanced infotainment display to support a safer experience. Since the upgrade, I have experienced the opposite of enhanced safety. My infotainment screen and dash displays randomly go black and it restarts itself several times a day while driving. In addition to that, the blinkers malfunction when this happens. The most important safety issue is navigation outage on the displays. The inability to rely on the Google maps navigation within Volvo, or within CarPlay, results in my having to use my phone to input and view directions, taking my eyes off the road. It also disables to cameras when I need them. On 3/31 I emailed my sales rep asking if he'd heard of others having this complaint, he did not appear to be aware and asked me to make an appt with service center. I brought the car to Volvo on 4/2 where the service check-in employees did mention they were seeing many cars coming in with the same concerns. The technician was not able to confirm the issue but said they would contact Corporate and let me know of a response, which was 15 days ago. According to online searches, multiple other Volvo drivers are experiencing the same. Since we have become so dependent on the driver assistance features, and this issue is now occurring, I have become a nervous driver in a brand of car that is marketed as one of the safest vehicles in the world. I get worried that my BLISS or lane assistance or other driver assisted features will malfunction as well. No notifications from Volvo have been received thus far. I have not contacted the Corporate offices of Volvo yet. Please take this safety issue seriously.

2018 Volvo XC90, VIN [XXX] , 54,618 miles. Original owner. All service performed exclusively at Volvo Cars West Houston (same dealer, all three failures). Volvo Technical Journal TJ 34648.1.2, titled "Prior Approval - Lack of airflow causing poor cabin cooling," is classified as a Product Fix and explicitly lists the 2018 XC90 as an affected vehicle. This TJ required the dealer to submit a Prior Approval report to Volvo Corporate when installing the resistor fix. At 12,017 miles (August 2020), the dealer installed the evaporator resistor per TJ 34648.1.2, Part No. 32241228, under VST Operation 98734-2 — meaning Volvo Corporate has documentation of this vehicle's evaporator vulnerability on file since 2020. At 15,930 miles (March 2021), the AC compressor failed and was replaced under warranty, consistent with refrigerant starvation from the same underlying evaporator leak. The evaporator has now failed completely at 54,618 miles despite Volvo's own corrective measure being applied at 12,017 miles. The current failure (April 2026) includes a confirmed front evaporator refrigerant leak and AC discharge hose leak, documented by dealer borescope inspection showing corrosion on the evaporator fins and visual evidence of refrigerant oil residue at the discharge hose fitting. Dealer repair estimate is $4,406. This is a documented pattern failure across 2016-2018 Volvo XC90 models. Volvo Cars USA was contacted for goodwill assistance and denied the request within 24 hours without meaningful review. Case number [XXX].

The contact owns a 2020 Volvo XC90. The contact stated that while driving 35-40 MPH, the message "Vehicle Not in Park" was displayed intermittently, and the vehicle stalled. The contact was able to pull over to the side of the road. The vehicle was restarted after several attempts and was driven to the residence. The vehicle was then taken to the dealer, where the contact was informed that no failure was found. The vehicle was not diagnosed or repaired. While investigating the failure online, the contact became aware that it was a common failure, and that the dealers were unable to duplicate the failure. The manufacturer was not notified of the failure. The failure mileage was approximately 79,000.
