2020 Toyota C-HR: grinding or squealing brakes

Filed Aug 17, 2026 · Transmission · TX

CVT bearing disintegrating. Expected repair cost is $10k-$12k. Purchased about a year ago and still owe almost 20k on the loan. This is the car that was intended to be used by my daughter but cannot trust this to make the drive. There have been no warning lamps or system messages just a metal on metal grinding sound. This is a known issue with this model of vehicle and there is already a warranty enhancement for this issue on 2018 and 2019 models. Mine is a 2020 so they clearly did not fix this known issue. This started about a month ago as a slight high pitched whine and has quickly progressed to the point that we cannot use the vehicle.

While driving, my 2020 Toyota C-HR suddenly lost acceleration in the middle of the road, with the vehicle failing to respond to throttle input. This has now happened twice. There was no warning noise (no whining or grinding) beforehand, and the loss of power occurred without warning while the vehicle was in motion, creating a dangerous driving condition due to inability to maintain speed or safely merge/clear traffic.

I have a K114 CVT internal bearing defect. It is available for inspection upon request. Transmission issues are unsafe because it can cause sudden loss of acceleration, unexpected vehicle stalling in traffic, and delayed shifting or gear slippage. These sudden changes make my car behave unpredictably; risking rear-end collisions or loss of control. This puts myself, my passengers, and others at risk. I am unsure if the problem been reproduced or confirmed by a dealer or independent service center. The vehicle and/or component have not been inspected by the manufacturer, police, insurance representatives or others. However, the vehicle received Service in December 2025 for a transmission fluid replacement for maintenance and no issues were reported at the time. There were not any warning lamps, messages or other symptoms of the problem prior to the failure. The issues first appeared in mid-June, around June 15, 2026, where I could hear a grinding noise when I drove. On July 1, I was driving home and experienced stalling while turning right at a stoplight. I took the car in for a diagnostic inquiry on 7/18/2026 and was notified I had a transmission issue. I took it for a second opinion, where it was confirmed it was transmission. I took it to Toyota and on 7/22/2026, they confirmed it was transmission issues requiring a full replacement with no financial assistance citing my warranty has ended and my service history is not thorough enough. Toyota has already extended the warranty for Canadian drivers due to this exact safety hazard.

My 2020 Toyota C-HR is exhibiting clear, escalating symptoms of the known K114 CVT internal bearing defect, creating an active safety hazard while driving. The transmission has not failed completely yet, but it regularly experiences high-pitched whining noise, sudden hesitation during acceleration, and loud grinding-like noise which gets louder and faster as I speed up. This behavior creates a significant safety risk because the vehicle unexpectedly fails to accelerate when merging onto the highway / hesitates unpredictably at busy intersections, exposing me to the risk of a rear-end collision. The car is less than 6 years old, and a mechanic/dealership has diagnosed it as an impending internal bearing failure. Toyota Canada has already acknowledged this exact flaw by extending the CVT warranty to 10 years. However, Toyota USA refuses to act, forcing American drivers to choose between operating an increasingly unpredictable, unsafe vehicle or paying $10,000+ out of pocket to replace a component with a known manufacturing defect. I am filing this to urge the federal safety agency to investigate before this transmission suffers a complete, dangerous failure at highway speeds.

I started hearing a grinding noise coming from the front driver-side wheel well for about a week. Then one day, while backing out of my driveway, the car suddenly lost power. I was stuck on a slight incline and no matter if I put it in reverse or drive, the car wouldn't move—it just wouldn’t respond like it normally does. A few days after that, I was sitting at a red light with my foot on the brake when the car jerked backwards. Right after that, the check engine light came on, and I noticed the car didn’t handle the same. It felt sluggish to respond when I hit the gas. After the red light incident, I had the car towed to a shop. They told me it had a bad bearing and said the transmission needed to be replaced. I’m reporting this because it felt like a serious safety issue—especially with the car losing power and jerking unexpectedly. I’ve seen other people mention similar problems with this transmission, so I think it’s something that should be looked into.
