I was told by oxmoor dealership I had to talk to toyota corporate before I could get my car touched and that I did not need to talk to a lawyer. I called. Prior to the accident, the vehicle had been exhibiting multiple symptoms: an intermittent airbag warning light had illuminated briefly on the dashboard on a few occasions, and the vehicle had begun requiring noticeably longer physical distances to come to a complete stop at traffic signs and lights when not using cruise control. The vehicle was experiencing regular phantom seatbelt warnings—dinging as if a passenger was unbuckled when the seat was completely empty. The phantom seatbelt warnings i didnt think we're a big deal were occurring across multiple seating rows simultaneously in front and back. Directly preceding the crash, while making a turn, the vehicle swerved slightly. When I applied the physical brake pedal, the vehicle did not decelerate normally; instead, it experienced a sudden, abrupt forward acceleration surge into the building. I still haven't gotten my vehicle back or any information on what has been done or when I am getting my car back. I was also charged for an extra day for my rental when I was told to return it on the 16th. I haven't had a rental since then. I keep contacting oxmoor toyota and they said they were waiting on toyota corporate. I haven't had my car for a month. I tried to email. It was returned. My mailbox on my phone has been full of drs and other calls non stop. I texted online on the toyota page for the claim as well. Ive repeatedly asked the toyota dealership what is going on and I get we are waiting on corporate. I called toyota corporate again today and was told they would get back to me. I told the dealership. I am under medical care and in severe pain. Yes my safety was put at risk. Police and fire department were here the night it happened. They said they don't do a police report on private property. There is an insurance claim through state farm.

The contact owns a 2015 Toyota Highlander. The contact stated that the power liftgate consistently failed halfway through while opening and closing the liftgate. The vehicle was not taken to the dealer. The vehicle was not diagnosed or repaired. The contact became aware of information online about Technical Service Bulletin: SB0023/16, NHTSA ID Number: 10134306 (Structure, Electrical System); and associated the failure with the TSB. The manufacturer was made aware of the issue and confirmed that the vehicle was not covered under warranty, TSB, or a recall. The failure mileage was approximately 133,000.

The radio keeps freezing up all the time along with the back tail light area going in and out. I keep smelling like burnt wire smell. Engine sound really rough.
NHTSA complaint #11750492 — an unverified report by a vehicle owner.
The back hatch of the car has issues closing regularly. Nearly half of the time you push the button to shut the back hatch when it is open it will not close and has to be shut manually. Typically, it shuts an inch or two and then beeps at you and when you push the button again nothing happens but beeping. This is an issue because it is very difficult to close. Even as a 6' 200+ lb man who does strength training regularly, shutting the back hatch is difficult to do manually let alone for my much smaller wife. This has let to her having to ask for help from strangers in a parking lot to help close the door which is unsafe, particularly since we have small children. Toyota has acknowledged that this is a known issue and have stated that there is nothing that they can do to fix it. This acknowledgement came when the car was very new and my father was the owner and again just a few months ago when we brought up the issue again with Toyota.

While driving my navigation system/screen/radio screen goes completely black! Which is dangerous when I’m using gps on the interstate! It does not come back on until I restart the car.
NHTSA complaint #11746932 — an unverified report by a vehicle owner.
Four days after I took delivery of this used vehicle (April 25, 2026), multiple warning lights appeared at once: BRAKE, ABS, PARK, Check Engine, Blind Spot Monitor Unavailable, and RCTA OFF. An independent Toyota dealership diagnosed the vehicle April 27-28, 2026 (approx. 109,000 miles) and found (1) water leaking into the rear hybrid battery area through a sunroof drain "installed incorrectly," causing a Brake System Control Module low-voltage code, starting issues, a headlight only partially functioning on one side, possible air in the brake system, and a musty HVAC odor; and (2) blind spot monitor fault code C1AC2 (Slave Module Horizontal Axis Misalignment) - the blind spot and rear cross-traffic monitoring systems do not function reliably. At a second visit on May 4, 2026, recalibration was unsuccessful; per Toyota procedure the only remaining option is replacing the right-rear blind spot sensor. The technician wrote the cause is a mystery, "whether it be body damage related or electrical short." Toyota service records show the same C1AC2 code was documented during the selling dealer's own pre-sale inspection, and that in December 2024 another Toyota dealership pulled the rear bumper and found the RR blind spot sensor bracket bent, causing incorrect readings - a recurring safety defect that prior calibrations and repairs have not resolved. Separately, federal safety recall 23V865 (occupant classification sensors; the passenger airbag may not deploy as designed) was open and incomplete when I purchased the vehicle and remains incomplete, and Toyota service campaign 25TD01 (rear traction motor cable corrosion) is also outstanding. The defect has been reproduced and confirmed by two Toyota dealerships, reported to the selling dealer in writing, and reported to Toyota's customer-care center. The vehicle is available for inspection upon request. No crash, fire, or injury.

The only door that will lock or unlock using the fab key or the master lock button on the drivers armrest is the drivers side rear door. My vehicle is not able to be locked unless I do it manually and can not be unlocked unless i use the rear drivers side door. This has been reproduced by the dealership. There were no warning lamps or messages and no other symptoms. This has been going on for a month. I am being told by the dealership service department that 3 actuators failed at the same time. My lift gate also malfunctioned this year. Dealership diagnosed it with needing new struts. Not sure if this is related. Lift gate would not open or open only a small amount. This was using the inside button and the outside one as well.
NHTSA complaint #11741832 — an unverified report by a vehicle owner.
The contact owns a 2015 Toyota Highlander. The contact stated that while driving on several occasions at various speeds, the infotainment screen would go blank and the system would turn on inadvertently. This issue became more frequent, occurring approximately every 10 seconds. The power steering warning light also illuminated. The vehicle was taken to an auto parts store where a handheld diagnostic machine did not detect any failures or codes. The contact stated that while driving on several occasions at various speeds, the steering wheel became extremely stiff. On one occasion while his daughter was driving and turning the vehicle on a curved road, the vehicle veered into oncoming traffic. The contact stated that she managed to get the vehicle back to the correct side of the road, then stopped and inspected the vehicle. The vehicle was then taken to an auto parts store where a handheld diagnostic machine was used, but the failure was not detected. The vehicle was not diagnosed or repaired. The contact believes that the steering failure was associated with NHTSA Campaign Number: 15V144 (Steering). The manufacturer was notified of the failure. The failure mileage was approximately 99,800.
NHTSA complaint #11741329 — an unverified report by a vehicle owner.
Motorized struts to lift and close the rear lift gate have failed. The struts do work to open the lift gate but they do not work to close it. Manually closing the lift gate is extremely difficult because of the electric motors inside of the struts. A known problem by Toyota as they have issued a TSB. Toyota’s solution is to replace the struts at a cost of $1200. My concern about this being a safety issue: Closing the lift gate after accessing the spare tire is extremely difficult. If my wife would inadvertently open the lift gate, which does work, after leaving the grocery store to put all of the groceries in the back, she would not have the strength to manually close it. Obviously, the vehicle cannot be driven with the open tail gate. This is not any different than if any of the doors could not be closed due to defective hinges. The premature failure of motorized struts is a fairly common problem with Highlanders. ToyotaNation, which is a Toyota sponsored forum for owners to communicate with other owners about issues/problems, contains numerous posts about the failure of motorized struts on the rear lift gate. Your attention to this matter is greatly appreciated. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
NHTSA complaint #11738117 — an unverified report by a vehicle owner.
Door lock actuators, yes it is available for inspection. Doors cannot be locked or unlocked with a remote key fob or the interior power door locks. Lock defect poses a significant safety hazard in that a single or multiple doors may not lock at any time, whether the vehicle is on or off and despite actions or commands by the driver. The alleged defect is dangerous to passengers as it can cause unintentional door openings while a vehicle is in use, result in inoperable doors during emergency situations, and leave a vehicle and any contents therein more vulnerable to theft. This poses serious safety concerns, for example when vehicles are involved in vehicular accidents because the occupants may become entrapped when the Door Actuator Defect prevents an occupant from unlocking the doors. Furthermore, this defect jeopardizes the safety of vehicle occupants given that not all doors are capable of being manually unlocked from the exterior. Since owning my highlander I've taken it to the dealership several times for this issue. The front door driver and passenger were replaced and a lock switch however dealership claimed they could not recreate the issue for all doors yet the issue continued and is noted several times in service history. Even when under warranty they refused to change the parts despite multiple service notes and verbal compilations due to their claim of not being able to recreate the issue. There were no warning lights or messages or other symptoms prior to failure. I've had this car since 2019 and it's been an issue notably since 2021. I fear the safety of myself, my family and other passengers are compromised every time we enter the vehicle.

I noticed the smell of wires burning, a billow of smoke started emitting from the two levers used to heat the seats near the gear shift area. I was on the freeway and immediately pulled to the side of the road, turned off the car and called 911 before any flames were seen. There were no warning signs, lamps or other symptoms until the smell of burning wires and the smoke.

NHTSA complaint #11735118 — an unverified report by a vehicle owner.
The vehicle experienced a transmission failure at approximately 62,000 miles, which required a transmission replacement. Toyota replaced the transmission with a rebuilt transmission. Immediately after the repair, the vehicle began experiencing multiple issues that were not present prior to the repair. The vehicle initially would not reverse, and the battery was drained shortly after the repair was completed. Following the repair, the vehicle has continued to experience ongoing electrical malfunctions, including dashboard warning lights, system alerts, and dash lights flashing during remote start. The vehicle has also developed a rattling noise underneath the vehicle. The exact failed component has not been clearly identified. The dealership has provided changing diagnoses and has not provided written diagnostic documentation despite requests. The vehicle has been inspected by the dealership multiple times; however, the issues have not been resolved. During a recent diagnostic, the dealership stated that the catalytic converter is now the issue, but this does not address the ongoing electrical problems. These issues raise safety concerns due to unpredictable vehicle behavior and potential failure of critical systems while driving. Warning lights and system errors began appearing after the transmission repair and have continued since that time. The vehicle is available for inspection upon request.
NHTSA complaint #11730329 — an unverified report by a vehicle owner.
The vehicle experiences intermittent power steering malfunction while driving. Warning messages including “Power Steering Malfunction” and “Low Voltage Abnormality” appear, and the steering wheel becomes stiff and difficult to turn. This has occurred multiple times during normal driving conditions, including at low speeds and while turning. When the issue occurs, it requires increased effort to steer, creating a risk of loss of control. Additional warning messages have included AWD malfunction, pre-collision system malfunction, and lane tracing assist malfunction. These alerts appear simultaneously with the steering issue. The problem began shortly after purchase and has continued intermittently. The vehicle has been inspected, but the issue has not been resolved. This condition creates a safety risk, especially when driving with passengers.

NHTSA complaint #11727156 — an unverified report by a vehicle owner.
March 5th purchased a battery from Autozone Z net Fit Match that caused cascading electrical and life -safety risk while traveling from hewitt, TX to Washington DC for our families spring break trip including 4 minor children. Component: 12-Volt Battery / Electrical System / Power Steering / Service Brakes Summary: Vehicle suffered catastrophic failure of Power Steering and Braking systems while in motion due to the installation of an incompatible lead-acid battery recommended by AutoZone’s 'Z-Net' catalog. Despite Toyota Technical Service Bulletin T-TT-0523-19 (Jan 2019) stating this VIN requires an Enhanced Flooded Battery (EFB/AGM) for its Stop-Start system, the retailer’s database continues to misidentify standard batteries as compatible. This mismatch causes a voltage drop that disables critical safety modules ('Limp Mode'). I have video evidence of the catalog error. This is a systemic misrepresentation affecting 2017+ Toyota Highlander safety compliance.
