Toyota Highlander fire or smoke problems

Filed Aug 20, 2026 · Engine, Transmission · NH

I had been shopping, as I attempted to increase speed, my car wouldn't respond. I smelled something burning and I switched lanes because I needed a safe place to stop. I turned onto [XXX] in Pembroke (I think) and still had no forward (or backward) movement. The lower gears (D5 & D4 ) DID NOT show on the dashboard indicator. I called my husband and he came to me. Then we called AAA and had the car towed to Chichester Car Care. They couldn't fix my car. I then had it towed from Chichester Car Care to McGovern Toyota in Bow. NH.

This vehicle has a UA80 8-speed transmission that has prematurely failed. This is a KNOWN issue to Toyota and they have refused to provide a fix. It is a safety hazard when all acceleration stops when attempting to merge into heavy traffic (as had happened to me last week) or on a highway traveling at top speed. I have only 27,000 miles on this automobile and it failed with NO WARNING! Within a very short time frame the following occurred: the check AWD system, TRAC off, check engine and the transmission fluid at a high temperature lights appeared on the dashboard. Shortly thereafter I experienced a burning smell, suddenly no acceleration with a high TAC response and vehicle jerking. My transmission is toast. This would have ended very badly for me as it failed on a highway at speed with heavy traffic. Toyota needs to address this and recall and replace. Shame on you Toyota!

Complaint: I am writing to report a transmission defect in my 2018 Toyota Highlander AWD (UA80 8-speed automatic transmission). Prior to the check engine light illuminating, I noticed a burning smell coming from the vehicle. Subsequently, the following fault codes were retrieved: •P0741 – Torque Converter Clutch Circuit Performance/Stuck Off •P2714 – Pressure Control Solenoid “D” Performance/Stuck Off •P2757 – Torque Converter Clutch Pressure Control Solenoid Circuit Performance/Stuck Off These symptoms are consistent with the known defect described in Toyota’s Customer Support Program ZJC (POL19-04), which acknowledges a manufacturing defect involving an improperly bent washer tab inside the UA80 transmission. However, my VIN was not included in the covered vehicles under this program, despite experiencing identical symptoms. I am also aware that multiple class action lawsuits were filed in December 2025 against Toyota alleging the company knowingly concealed this defect from consumers for years. I am requesting the federal safety agency to investigate whether Toyota’s CSP ZJC coverage should be expanded to include additional affected VINs, and to consider issuing a mandatory recall for all vehicles equipped with the defective UA80 transmission.

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.

The contact owned a 2008 Toyota Highlander. The contact stated that while driving at approximately 20 MPH, an abnormal, booming sound was emitted from the vehicle as heavy, black smoke entered her vehicle. Due to the smoke, the contact's vision became obstructed, and the contact immediately shifted into park and jumped out of her vehicle for safety. It was unknown if there were any warning lights. As a result, the contact injured her right hip and strained her vocal cords. The vehicle quickly became engulfed in flames as authorities were called to the scene. The fire department extinguished the flames as both a fire and a police report were filed. The vehicle was towed to an independent mechanic, where it was deemed a total loss. There was no property damage. The origin of the fire was unknown, and an investigation was opened by the insurance company. The contact sought medical attention the next day and was treated for the strain on her right hip. The manufacturer was notified of the failure, and the contact was given a case number. The contact was also informed that she would receive a response from them within 45 days. The vehicle was destroyed. The failure mileage was approximately 100,000.

In early January 2026 there was rough/delayed shifting, whining noises, and fluid leaks. Probably linked to the faulty UA80E/F transmission type. The check engine light came on 1/15/26, I took it into a local repair shop. The mechanic flushed and changed the transmission fluid, replaced all of the spark plugs and the serpentine belt. I picked it up on 1/16/26. There was still shuddering, strange sounds (whining/grinding), and hesitation. On 1/20/26 I drove it and the rough/delayed shifting, whining noises, hesitation and burning smell started happening. The car completely broke down on the freeway and wouldn't drive at all. I had to slowly pull over to the shoulder of the freeway and have the car towed to the repair shop. They inspected it and said I need a new transmission, and it cannot be fixed. I believe the next steps are to have it towed to the toyota dealership to have it looked at.

When turning on the heated steering wheel and about 5-10 minutes, it seems there is smoke coming from the steering wheel leather and it’s very hot that almost burnt my hand and forced me to take my left hand off. I immediately turned the heated steering wheel and stopped. There is a burning spot left on the steering wheel also. The heating option still can be enabled and the same situation repeats (like no fuse was broken)

I purchased a 2021 Toyota Highlander in June of 2024 with about 45k miles. The transmission completely failed at 67k miles, when I brought it in to have checked in April of 2024. This is not covered under warranty and is costing 7-8k in repairs and over 3k in rental vehicles. I'm told the transmissions are on back order for 3-6 months. No lights went off in the car warning me of this. I smelled burning fumes on and off and reported it to the service dept around 59k (January 2024) miles. I did feel a jump at times, but didn't report that. After my routine oil change at the end of March of 2025, I heard a whining noise only when accelerating and would immediately stop when I released my foot. Two Toyota Service departments diagnosed my car with a failed transmission. I haven't been able to drive my car for 2 months now. My family's safety has been at risk while this issue with this transmission failure has been known and not reported to the consumers prior to my purchase in June of 2024. Potential consequences to a failed transmission while driving are as follows: -Sudden Stop or Coast to a Stop: The car might stop moving entirely, especially if internal components seize or it just loses power and I coast to a stop. -No Response to Acceleration -Pressing the gas has no effect, which is dangerous if I'd be in traffic or on a highway. -Locked-Up Transmission -Rare but possible, especially in catastrophic mechanical failure which could cause wheels to lock briefly. -Stranded

The Check Engine light came on and I took it into Toyota of Downtown dealership where I was receiving periodic maintenance. After 2 days, they said the light was out but they hadn't found the cause. I could either leave if for a few more days or take it and bring it back if the light came on again. This was early August. I chose to take the car & when the Check Engine warning light came on again, I took it in on Aug 15, 2024 before I left to Portland to give them more time. I returned on Monday & couldn't reach them. The next day they informed me that while on a test drive, there was a loud bang, it started smoking and by the time 911 arrived it was on fire. After a 2 month investigation by Toyota's Engineering Analysis fire inspection, they concluded Toyota was not involved. The dealership has not provided me with the report although I've requested it but they aren't accepting responsibility either although it was in their possession when the fire occurred.
