The contact owns a 2017 Toyota Highlander. The contact stated that the vehicle was parked but still running in a driveway on an incline. After exiting the vehicle, there were abnormal beeping and ticking noises detected, and the vehicle began to roll down the street. The contact and daughter were pinned between the door and the vehicle. The contact's daughter sustained injuries to her chin and teeth. The driver has lumps and bruises on her leg and back pain, but medical attention was not provided. The rear wheels were on the curb and hit a trash can, and the vehicle stopped rolling. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 70,000.
On March 9, 2022, the transmission in my 2017 Toyota Highlander completely failed while I was driving on a busy road during rush-hour traffic. I was approaching a stop light and was braking when the vehicle lunged forward and then stopped moving. I pressed the accelerator to move up to the stop light but the vehicle would not move, even though it was in Drive gear. I changed the gear to Park and then back to Drive and the vehicle still would not move. The engine was revving and the RPMs were increasing but the vehicle would not move while in Drive gear. I also tried to reverse but the vehicle still would not move. I had to exit the vehicle and ask for assistance from other motorists to physically push my vehicle off the road into a parking lot so as not to continue blocking the busy road. …
Transmission problem in our 2017 Toyota Highlander started at 104k miles. unfortunately for us out of warranty and lucky for dealer and manufacture who shifted the cost to consumer outside warranty. We experienced delayed and sudden shifting, slow at accelerating. One day the engine kept revving but car was not moving. Also reverse gear stopped working. We brought the car to local dealer, who gave us every excuse in the world that it was our driving habit, we take it off roading etc etc. The truth I am a very careful driver which I am sure the dealer laughed at me for saying that. Never took the car off roading, or on monthly long trips. All services were completed by the dealer. The quoted us a cost of $9500 plus tax plus $250 diagnosing fee. …
Several times on the highway when getting up to speeds around 70mph the transmission would rev but not accelerate or maintain speed - usually slowing to around 40-50mph or slower depending on the hill grade. The check engine light came on, initially was told it was probably a fluke. The mechanic couldn't get it to do the same thing for him. Brought it back again when the issue persisted. He suspected the transmission was slipping, referred me to the dealer. The light was off by then, the dealer said they couldn't diagnose with no light so we needed to wait until it came on. It finally came on while driving on I71 but the car completely lost all power and I was stranded on the side of the highway and had to be towed to the dealer. I did a quick google search and saw a class action suit for this vehicle and year in which the plaintiffs complained of the same issues. …
About two weeks prior to the transmission failing, I started hearing a high-pitched whining coming from the transmission, difficulty shifting, and lurching forward when engaging the gear. On the evening of October 4th, my wife was driving at 65 mph on a busy freeway in Atlanta when the vehicle lost acceleration. She was nearly hit while stopped on the freeway. Fortunately, kind motorists got out of their cars and pushed her to the side of the road. The car was towed to a Toyota service shop, and we were advised they could not do the repairs. The mechanic stated it was a known internal Toyota issue. I did some research online and found hundreds of posts from Highlander owners of 2017-18 vehicles complaining about issues with the transmission failing. …
2017 Toyota Highlander XLE Why hasn't Toyota issued a recall?! My transmission failed at 2AM on the Florida turnpike 140 miles from home, after a physically and emotionally exhausting day moving my daughter to college. I slept in my car 7 hours, scared, waiting to get towed. The closest shop that was open early on a Saturday was an hour away in the other direction and when I got there, they told me they wouldn't be able to look at it until Monday. Pointless to pay 2 nights at a hotel, so I got an Uber to get a rental to get home. It wasn't bad enough when I found out the cost to replace the transmission on a car with 96k miles (my Camry had 300k when I sold it), but even if I agreed to pay, the transmission is backordered, and it could be months. Months! I had to pay the diagnostic fee - completely understandable - and I needed it moved to avoid a $75 per day storage fee. …
Our Toyota Highlander XLE which has 137000 miles on it has the very well documented "whine" issue with the UA80 transmission. This "whine" issue/failure has resulted in at least two TSB's to be generated by Toyota and is considered the beginning stages of a total transmission failure. It impacts 2017 through at least 2022.The symptoms (whine sound/grinding sound/DTC codes/rough operation/unexpected slippage) are identical in all years. Toyota covered a small subset of the total number of failures suggesting an improperly installed "washer" was at fault. The online community impacted by this failure, most of which are outside of that serial number range, clearly do not feel the same way. Failures have occurred on vehicles with as little as 50,000 miles. The issues of transmission slippage/failure to maintain speed/failure accelerate are all safety risks. …
Highlander shift issue 11/14/2023 On 11/14/2023, our 2017 Toyota Highlander, vin# [redacted] , upon driving the transmission decided on its own to disengage. Our Highlander stopped propelling itself in either direction. We had to manually push our vehicle into a parking spot and await the tow truck. Our Highlander is in mint condition with 71,400 miles on it. This was scary because the vehicle would shift on the shifter, but for some reason the transmission would not engage. The engine worked perfectly fine. We had the Highlander towed to the nearest Toyota dealer who pushed the vehicle into their garage and placed on a lift. The Highlander had no idiot lights on, no cable issues, fluid was fine per the Toyota Technician. The Toyota Tech placed the vehicle on their main computer and there were no error codes. …
There is a toyota service bulletin for known transmission issues with this vehicle. I had noticed that my gears weren't shifting properly. The dealer checked vehicle and said transmission was bad, and that toyota would replace it, for free. However, the part would take one month to arrive. This all occurred on 1/9/2024. I was told by the dealer that Toyota would not cover a rental car while the part was on order, but only for the repair itself. The dealer told me the Toyota recommendation was to not drive the vehicle -- but other customers had done so until they received their parts for repair. I picked up my vehicle after work at approximately 7:15pm. While driving, the vehicle completely shutdown on me in a major highway miles from downtown Philadelphia, in a flooding rainstorm that produced nearly 4 inches of rain. …
In January during an oil change i was advised that my Toyota had a timing cover leak which is a costly repair. At this time my car was at 148k. i researched it recently and found that it could be dangerous to drive with this leak that Toyota did not advise me about after i had several phone calls with their corporate office and dealership. And even though it is a common problem with their 2017 Highlander they would not take responsibility for fixing it. It was disappointing after getting all of the service recommendations done that i would have to pay $4500.00 for engine work for a seven year old vehicle. This cost was a hardship for me because I'm still making a car payment. I also had to replace the battery every 1.5 years. The battery warning light never came on, leaving me stuck at an intersection until the tow truck arrived. …
