Toyota C-HR check engine light comes on

Filed Oct 24, 2026 · Transmission · AR

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 loss of propulsion or leave the vehicle disabled in traffic, potentially putting myself and other motorists at risk. Although I have not experienced a complete loss of propulsion, the worsening noise, sudden clunk and jerk while reversing, and dealership’s recommendation to replace the transmission have raised concerns about the vehicle’s continued safe operation. I am requesting that the federal safety agency document and evaluate this transmission failure to determine whether it may represent a potential safety defect affecting Toyota C-HR vehicles.

The contact owns a 2019 Toyota C-HR. The contact stated that the vehicle occasionally failed to start. On another occasion, there was a tire blowout while driving 70 MPH. The contact replaced the battery, and the instrument panel displayed several warning lights, including the Check Engine, Lane Assist, and Forward Collision. After an initial dealer inspection, the diagnostic test was inconclusive. The contact drove the vehicle off the lot, and the warning lights returned immediately afterwards, and the vehicle was taken back to the dealer for additional diagnostic tests. The dealer subsequently identified a failure with the valve lift controller and an inoperable housing sub-assembly. The parts were replaced. The manufacturer had not yet been notified of the failures. The failure mileage was approximately 96,000.

Transmission completely gave up. Took it to be looked at and the people who service my car regularly were incredibly confused. No service light. No warnings. Nothing other than a rattling sound when I accelerated was the indicator. I searched online and this model has recalls outside the U.S. for the SAME reason but recalls are not available here in the U.S. so many customers are suffering because of this car. I too cannot afford to replace it & I barely had it for 4 years so it wasn’t even completely paid off once it died. I have a commute on the interstate of 30 minutes to and from work every day. I’m so relieved I took it to be checked before I put myself in danger on the road. It had absolutely NO warning to let me know that it was having transmission issues. Not even a check engine service light or error. My service area didn’t even notice anything wrong when I had my oil changed 2 months before I made them check the noise. It has been inspected by 2 local repair businesses. The only symptom I had was a very light rattling noise. I thought it was the plastic cover underneath my vehicle. If I didn’t go for that reason, I don’t know what would’ve happened to me. They had to bring in a seasoned repair man to find out the culprit in the end & I received the bad news before they closed up shop

My front camera sensor light came on stating it was unavailable, then turned back on after a few minutes. About a week later on several occasions, the emergency brake notification came on when I was on the freeway with no vehicles in front of me to cause this. There has been an excessive whirring sound coming from the engine also. With these issues there have been no warning signs including check engine lights or other vehicle maintenance lights on. Reading complaints from other Toyota, CHR owners with similar issues, and stating they’ve had costly transmission failure brings a great deal of concern for my safety and those on the road.

I was driving on the highway, roughly going 70-75 miles an hour, and as i began to exit the highway the check engine lights on the dashboard came on and the vehicle seized up. Upon inspection at the Toyota Dealership, they said that the transmission has been broken, as well as shrapnel metal being in the axles of the front wheel drive, stopping the car from moving. As i was stuck on the exit of the highway, NTTA was forced to block the exit as well as tow my car to the nearest parking lot, causing traffic jams on the highway. Upon research I found that issues with the transmission is not uncommon in this vehicle.

The CVT transmission in my 2018 Toyota C-HR failed suddenly while driving. There were no warning lights, check engine indicators, or dashboard messages before the issue occurred. The only symptom was a sudden whining/whirring noise from the transmission area. The vehicle has been regularly maintained and serviced through ToyotaCare until the coverage expired in 2023. The failure happened on 11/02, and the car is currently available for inspection upon request. This failure created a potential safety risk because the car unexpectedly lost power and could not accelerate properly in traffic. The problem has been confirmed by a Toyota dealer (Toyota of Anaheim), who diagnosed it as an internal CVT transmission failure. The vehicle has not yet been inspected by Toyota corporate, police, or insurance representatives. There were no warning lamps or messages before the failure , only the noise that began a month ago and it when i accelerate, I decided to take it in to the dealership to take a look at.

I was driving down the street, n while pressing on the gas , the car felt like the car was slowing down, even though still pressing the gas. You could hear the Rev of the engine. I was in a middle lane at the time, n was out at risk as I could not accelerated safely to get to an outside lane, car coasted where I was able to pull into a parking lot. Car will crank, can hear car rev, while putting in gears, seems you can hear the gears shift. However the car will not move in any gear. Few mechanics pass by the area and stated the transmission has failed. Only 120k on car. There is no warning light that lit up, no check engine light. Just all of a sudden, out.
