2017 Toyota Highlander

Transmission intermittently allows the RPMs to double from 2,000 to 4,000 RPMs. It occasionally displays trouble codes, and exhibits a grinding, whirring noise. An Independent transmission shop confirms that it needs to be replaced. Toyota has issued a recall referred to as Customer Support Program ZJC, but their representatives claim that our vehicle does not qualify, even though the date and model of the transmission clearly Falla under their parameters.

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.

In city driving, vehicle began exhibiting slightly delayed shifting from 1-2 and 2-3. Downshifts from 3-2 seemed slightly rough. Approximately 5 minutes later when accelerating from a stop on an uphill grade, the shift from 2-3 was delayed (2nd gear disengaged, engine speed increase ~1000RPM, then shifted to 3 abruptly). At next stop, lower gears where not available. Vehicle seemed be in 4th(?) gear when accelerating from a stop. Very little power available. Had to engage hazard flashers and other vehicles navigated around our vehicle. Managed to limp car ~ 1 mile to home. Approaching driveway, Master Warning Light, Check Engine Light and 4WD Warnign light all illuminated. This issue created a loss of power that impaired the drivers ability to maintain a safe speed relevative to traffic. Had this issue occurred during high-speed operation, the vehicle may have been disabled in a high-risk area. Transmission appears to be unreliable.

2017 Toyota Highlander experienced delayed and rough shifting in 3rd gear. Safety of acceleration is affected, especially merging onto highways. Diagnosed with bad transmission on 12/26/2023 by Toyota service. There was no warning lamps or messages prior to failure. Unknown cause, car is regularly serviced per manufacturer recommendations by Toyota. Part on backorder for approximately 3 months.

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. If Toyota knows there is a problem with this vehicle and its transmission, then why is there no recall? And if I'm being told the I should not drive the vehicle, then why isn't it mandated or required for them to provide me a rental - especially since this is the fault of Toyota?

Highlander shift issue 11/14/2023 On 11/14/2023, our 2017 Toyota Highlander, vin# [XXX] , 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. The Tech reset the computer on the vehicle with a Toyota Master computer, and the vehicle started to work as normal. I consider this a huge issue and I thank God that my wife was not on the interstate highway when this happened.

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. I found Toyota Customer Support Bulletin POL [XXX] dated 4/18/2019, REPAIR COVERAGE FOR UA80 TRANSMISSION ON CERTAIN 2017-2018 MY SIENNA AND CERTAIN 2017-2018 MY HIGHLANDER VEHICLES. The mechanic said the failure code with a failed transaxle and all the symptoms my vehicle experienced were consistent with the bulletin. My time period for the bulletin was for cars produced from November 2016 to December 2017. My vehicle’s manufacturing date was 12/8/2016. Toyota claims my vehicle although produced during this time was not impacted. It is my belief that Toyota was aware of multiple failures on UA80 transmissions on vehicles produced from 2016 to 2020 and deliberately identified a smaller number to avoid a recall.

Driving on the highway vehicle suddenly drop speed. I was able to exit but not proceed forward once exiting. The vehicle was towed and diagnosed with need for new transmission. There was a customer support program bulletin POL 19-04 noting similar problems. However, Toyota is stating this 2017 is not associated with the program. The whine noise and reduced power are all listed with this program. The vehicle sudden reduce power may have resulted in a major accident on busy Atlanta highways. A known transmission issue that Toyota is not willing to support customer in resolving is unbelievable. I was basically told because the vehicle was not serviced at a Toyota dealership regularly, they cannot support.
