2020 Toyota C-HR power train problems

“I am reporting a transmission failure involving my 2020 Toyota C-HR Limited at approximately 111,852 miles. For several weeks, I had noticed an unusual humming or dragging noise coming from the front driver’s side of my vehicle while driving. The noise became increasingly noticeable, but I did not know what was causing it. On October 8, 2026, after driving approximately 30 miles at highway speeds of around 75 mph, I arrived home and began backing into my driveway. While the vehicle was moving in reverse, it suddenly made a noticeable clunk and jerk. This was the first and only time I had experienced the vehicle jerking. I took my vehicle to an authorized Toyota dealership on October 9, 2026. The dealership recommended replacing the transmission assembly. I was verbally informed that an internal transmission bearing had failed. Throughout the weeks leading up to the diagnosis, my vehicle never displayed a check engine light, transmission warning, or any other dashboard warning message. I regularly drive approximately 60 miles per day, including interstate travel. I am concerned that an unexpected transmission failure while driving at highway speeds could cause a…”

“Fred Anderson Toyota dealership said a bearing which is internal is going bad The manufacturer does not sell the kit as my transmission is called a CVT and it’s a sealed transmission. I will need to replace the entire transmission. Also my vehicle is also discontinued.”

“Transmission is going out. It is sitting at the Toyota dealership in silsbee Texas. It has been recalled in Canada but not the US . IT HAS WELL KNOWN PROBLEMS AND THERE IS A CLASS ACTION LAWSUIT. It is unsafe for me to drive and others on the road way. Toyota will not replace it. Said it was out of warranty only having 133k miles on it”

“The vehicle is exhibiting symptoms of the widely documented internal differential/output bearing failure associated with the Toyota K114 CVT transmission. When coasting—even with the engine completely turned off—and during mechanical rotation of the front wheels, there is abnormal metallic clicking, clacking, and mechanical play apparently emanating directly from the center of the transaxle housing. This internal component degradation poses a potential safety hazard. A catastrophic failure of this bearing could lead to severe metallic debris entering the sealed CVT system, potentially resulting in drivetrain lock-up or an instantaneous loss of motive power at highway speeds, creating a serious risk of a high-speed collision. This is a documented recurring failure in the K114-equipped C-HR. Toyota Canada has acknowledged this mechanical failure in 2018–2019 C-HR vehicles by issuing a 10-year/193,000 km Warranty Enhancement Program covering CVT failures associated with internal bearing failure. Similar failures have also been documented in U.S. C-HR vehicles, including 2020 model-year vehicles, although no equivalent U.S. warranty enhancement has been extended to…”

“CVT failing, causing extreme bearing noise. Toyota insisted lifetime fluids with no transmission service or fluid changes. At 147000 miles it is noisy with no warning lights and no recommended service.”

“Transmission went out 3,400 miles past the 60k warranty. Vehicle taken in at 59k miles and told there were no issues. Filed good will warranty claim. Toyota needs to do a recall. This is a know problem. 2018 and 2019 models recalled. 2020 models same issue, why no recall for 2020. I have read at least 17% of 2020’s have already failed.”
