2018 Volvo XC90 problems

SEAT BELTS

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.

UNKNOWN OR OTHER

The air conditioning evaporator core has been widely known to freeze and crack on 2016-2021 models of the xc90 which sends toxic refrigerant smell thru the vents. This is a big safety hazard and should be recalled. Volvo knows about this but only does a goodwill repair to loyal customers who purchased the vehicle new and have all service records from the dealership. This is a $4000 repair for everyone else for a manufacturer defect and safety issue

VEHICLE SPEED CONTROL

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.

SERVICE BRAKES

My Volvo's XC90 brakes have failed twice. At around 95,000 miles, my brakes stopped working, and then I had them repair it. They charged me close to $3,500, which they said they were able to cover under warranty, and I only had to pay the deductible, which I don't remember. In less than nine months, at about 104,000 miles, the same problem persists. Both times I was driving the car, by God's grace and luckily, I was under 10 mph. I literally parked and started driving after that, and I realized the brakes weren't working again. I'm just thankful to the Almighty that I was not at 55 or 60 mph on a freeway when the brake stopped working.

UNKNOWN OR OTHER

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].

LATCHES/LOCKS/LINKAGES:DOORS:LATCH

Rear Drivers door (left) fails to latch. Volvo has an updated part for better water ingress prevention, then the part that was used to build the car. The problem is that water enters the moveable window, runs down the metal channel separation gthe fixed and moveable window, and enters the door latch mechanism. This is extremely dangerous, in that the door may appear closed, and the vehicle may allow the driver to move forward or backward, but the door is not latched and can fly open leading to death! This is an issue known by Volvo, hence the updated OEM replacement part, however they are grossly negligent in not reporting or self recalling vehicles for this issue.

LATCHES/LOCKS/LINKAGES:DOORS:LATCH

At random times the back doors will not open, from the inside or outside…hit all the unlock buttons and will NOT open. If this is not a massive safety issue, I don’t know what is…. If we get in a wreck and our car is on fire and we cannot instantly get ourselves or our children out quickly that’s a problem… if we wreck on the freeway and we see vehicles coming at us and we cannot quickly exit. This is a problem. For a car company to not address this it is gross negligence… we own a Ford focus it’s been taken in about three times for door recalls, but we never even actually had an issue…Volvo being a luxury car company and choosing to ignore this issue at the expense of the consumer has went on too long! This hasn’t happened only once, has happened sporadically multiple times

POWER TRAIN

My car completely locked up on the road and came to a screeching stop. This car is known for having the ERAD completely fail and it could have caused it to have a serious accident. It has also caused my car to plummet in value losing over 30k in just 3 years. Now my repairs cost nearly what it’s worth and aren’t guaranteed to actually fix it. It’s terrible. I’m so upside down n my loan due to this issue that they dealerships refuse to help on. The dealership acknowledges it is a design flaw but yet they won’t help. I have an email stating that it is a design flaw

POWER TRAIN

On 8/20/2025, my 2018 Volvo XC90 T8 suffered catastrophic failure of the Electric Rear Axle Drive (ERAD). The vehicle suddenly developed a loud whining noise from the rear and became undriveable. This ERAD had previously been replaced under warranty at Boston Volvo Cars. On 10/28/2025, Queens Volvo inspected the vehicle and confirmed the failure was caused by improper prior service. Their technician documented that the ERAD housing was likely not properly torqued, which led to transmission fluid leaking over time, sludge buildup, and internal damage to gears and motor. The failure was sudden, confirmed by an authorized Volvo dealer, and the ERAD is no longer serviceable. This created a safety risk by causing immediate loss of propulsion and stability. If it had occurred at highway speeds, the risk of crash would have been significant. The failed component remains available for inspection.

ELECTRICAL SYSTEM

3 weeks ago we had the transmission module fail on our vehicle while it was being driven. According to Volvo forums, this is a multi-model year, multi vehicle issue for those with sunroofs. Accrding to the dealer in our case, the seal failed, and water runs into the compartment where the transmission module is located, causing it to fail. We had it happen twice, and both times on the highway, with the engine running ragged causing it ot accelerate and then quickly decelerate. There were 3 warnings that popped up-"Gear lever locked," "transmission acceleration performance reduced," and "Parking Brake unaavialble." It happened twice and and was towed to the dealer both times, as it was not drivable-once the vehicle was parked it would no longer move out of park. The first time the diagnosis and module reset was comped by the dealer (Borton Volvo, Golden Valley, MN) and the second time, the transmission module was "dried out," and the sunroof seal was replaced, which was just under $700. It is available to be inspected if necessary. The vehicle was a hazard to others on the road while it was "acting up." Dealer was familia with the issue. No inspection was done other than by the dealer Warning lamps as outlined above

VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM

The contact owns a 2018 Volvo XC90. The contact stated that the A/C unit failed to operate as needed, causing the HVAC system to become inoperable. The vehicle was taken to a dealer where a diagnostic test was performed, which showed that the evaporator core inside the HVAC system was cracked and needed to be replaced. The contact attempted to have the part replaced; however, the contact was informed that the part was on backorder. The vehicle was not repaired. The manufacturer was notified of the failure but offered no assistance. The failure mileage was 100,000.

STEERING

While actively driving into an intersection, driving on the street and or stopped at a light or at a stop the vehicle will shut off, the lights on the dashboard will sometimes be on, other times go completely black, a notification pops up on the dashboard saying "engine not in P". There is no way I'm aware of to re create this action. My children's safety as well as mine has been put at significant risk and in harms way as well as others due to the severity and nature of this unexpected risk while driving on the freeway, through intersections and in general driving through traffic and busy streets. I've had multiple close calls of almost being hit when the car stopped while I'm driving with my children. The problem has yet to be reproduced by the dealer at this time however we have photos and video of it's ongoing safety concern. It has not been inspected by the manufacturer nor police but is currently at the dealer undergoing inspection. There has not been any notifications or warnings prior to any one of these serious events, the message only comes up when the car is off and won't go.

ENGINE

The engine coolant bleeder hose in my 2018 Volvo XC90 cracked in the middle of my journey causing a severe coolant leak. This happened in August of 2024 while driving and the engine coolant suddenly started showed warning with low level and the engine started overheating. The vehicle would not accelerate past 20 mph, and the temperature warning light flashed continuously, creating a safety hazard in traffic. The Volvo dealership diagnosed the issue and confirmed that the coolant bleeder on the supercharger is broken and leaking. They replaced the bleeder hose and vacuum fill system. I believe similar issues happened to the 2016 models and a recall was issued for the coolant bleeder hose (part # 32249907-0) to be replaced by Volvo. This has not been recalled for the 2018 models, making it an expensive replacement for me. I urge NHTSA to investigate Volvo XC90 coolant hoses for material defects, as this issue endangers drivers through unexpected breakdowns and engine failure.
