2020 Toyota C-HR

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 NHTSA to investigate before this transmission suffers a complete, dangerous failure at highway speeds.

I purchased my Toyota CHR 2020 LE right off the lot in 2020. In 2023, I had to replace my first transmission, THANK GOD THAT ONE WAS UNDER WARRANT. It is now 2026 and I am again, having to replace my transmission. This is a real safety concern. Just in the beginning stage of failure my car is sluggish to accelerate and I live in Houston, TX! People will run you over here if you aren't careful. No to mention the highway robbery that is being committed for having to pay half the cost of my car for a new transmission that is absolute garbage. It is absolutely ridiculous that no one has done anything about this yet. You sell a vehicle you know is having these issues without disclosing them. Shame on everyone involved.

The motor mounts broke when it hit a pothole and that snapped the wiring harness which caused the transmission to shift. Toyota dealership says it needs a new CVT transmission replacement. The engine has shifting issues. My insurance adjusters believe that the transmission failure is due to wear and tear, but the car did not have issues before the pothole. There were and are no warning lights or messages prior to and after the incident. I got the engine wiring harness and motor mounts fixed and there was still a noise and lag while accelerating and they finally said it was the transmission the second time I brought it in and that wasn’t covered by insurance. I’ve only put 11,000 miles on it and I’m the second owner. I bought it from a Lithia Nissan of Clovis.

The negligence displayed by the CarMax Orlando staff not only violated the terms of our purchase contract but actively endangered my life and the lives of others on the road. 1. Timeline of Events and Staff Negligence On 04/30/2026, I purchased the above-referenced vehicle from CarMax Orlando. Upon attempting a test drive, I was denied by sales consultant Boris Iniquez, who stated the vehicle could not be driven until it was cleaned. On 05/01/2026, I took delivery and immediately noticed the brakes were non-responsive and emitting a loud "air brake" sound. I returned to the dealership on 05/02/2026. Mr. Iniquez performed a ride-along, personally witnessed the brake malfunction, and was informed of my immediate need to drive 450 miles to Atlanta, GA, for my role as a Site Inspector. Rather than providing a safe loaner or grounded vehicle, Mr. Iniquez and the acting manager explicitly instructed me to drive the vehicle to Atlanta, asserting that the car had "passed all inspections." 2. Mechanical Safety Failure Upon reaching Atlanta, the vehicle's condition became untenable. On 05/07/2026, CarMax GA inspected the vehicle and found: - Total failure of all four brake pads. - Front rotors requiring immediate replacement. It is mathematically and mechanically impossible for a vehicle with metal-on-metal rotors and failing pads to have passed a legitimate 125+ INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (F

While taking off in my 2020 Toyota C-HR on the highway, the CVT transmission suddenly failed, resulting in an immediate and significant loss of propulsion power. The vehicle did not fully shut off but lost the ability to maintain normal highway speed, requiring me to rapidly reduce speed and carefully maneuver the vehicle to safety in active traffic conditions. This created a serious safety risk due to unexpected loss of acceleration and potential inability to maintain highway speed in traffic. The failure occurred at approximately 117,700 miles and shortly after purchase. The vehicle had a documented history of regular maintenance performed at Toyota dealerships approximately every 3,000 miles. I was later informed by Toyota service personnel that the vehicle had previously been documented on 2/2/26 in the manufacturer’s internal system with a CVT fault and a recommendation for transmission replacement prior to my purchase, which was not disclosed in any public vehicle history reporting system. This raises a major safety concern that the transmission failure may be part of a broader pattern of CVT reliability issues affecting this model and drivetrain family. I am submitting this complaint due to the sudden loss of propulsion at highway speed, which presents a potential safety hazard to drivers and surrounding traffic. And deceptive practices of undisclosed known safety issues by Toyota of USA.

The contact's customer owns a 2020 Toyota C-HR. The contact stated that while driving at various speeds, there was a grinding and whining sounds coming from the transmission. The contact diagnosed the vehicle and determined that the CVT transmission was failing and needed to be replaced. The vehicle was not repaired. The manufacturer and local dealer were notified of the failure, but no assistance was offered. The failure mileage was 76,000.
