2018 Toyota C-HR: check engine light

Filed Apr 9, 2026 · Transmission · GA

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.

The CTV transmission failed with a check engine light and multiple error codes including front end collision warning failure and Electronic brakes failure. The car had supposedly passed a 125 pt inspection less than 5000 miles before this. In addition, the fluid had been replaced as recommended at about 60,000 miles.

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.

The contact owns a 2018 Toyota C-HR. The contact stated while driving 20 MPH and depressing the accelerator pedal, the engine revved loudly while the transmission was stuck in low gear. The check engine, power steering, Forward Collision Avoidance, and other unknown warning lights were illuminated. The contact stated that upon exceeding 25 MPH, the engine revved loudly to 4,000 RPM. The contact drove to the residence, where the vehicle was diagnosed by a mobile independent mechanic. The mechanic determined that the failure was related to the transmission. The vehicle was not repaired. Glen Burnie Transmissions was contacted, and the contact was informed that there were several similar vehicles at the location being repaired for the failure.

A noise occurs when driving. had it checked by two sources one being the Toyota dealer, the other independent. Both concluded the transmission was at fault. The dealer quotes me a price to replace(no repair option) of $13,000. There was no engine warning lights or such to alert me to the problem- just the noise. I think the safety issue is obvious. If I continue to drive the vehicle and the transmission fails especially on a highway at higher speeds than street driving- who knows what bad outcome that might be! This seems to be a very wide problem with these transmissions. There is a lot of complaints posted for this model in particular but also across years of cars- 2018-202. It seems to be a known problem by Toyota but no recalls, TSBs or efforts to resolve.

I did not notice any issues or irregularities while driving, but when I started my car to leave one morning, the check engine light was on. I immediately dropped it off at my local toyota dealership. The problem ended up being a faulty fuel pump valve which needs to be replaced, along with a complete fuel system cleanout. This is an expensive repair, which upon researching the issue, I have found that thousands of other toyota models have been recalled for. I would like to request that they look into adding the ch-r to that list because apparently there is a problem as my car is less than 3 years old.

I purchased this car on june 26th 2018, the car had been working just about fine until april 24th 2020. I was running errands and my car had not shown any signs or warnings about needing service or that something was wrong. I turned on my car, I backed up a little and the camera malfunctioned and I heard a weird sound, then the car turned off by itself and then it wouldn't turn on. I called aaa and they tried to charge the battery, it wouldn't charge at all. My car was towed to the dealership, they deemed the battery to be dead and it was replaced. On september 19th 2020, the new battery was dead again, from being parked, it wouldn't turn on, called aaa and this time they were able to charge the battery and the car turned on. I got on my way back home, after 5 minutes of driving, the stereo, A/C, dashboard and headlights started malfunctioning. Dashboard had some service lights on and the message "abnormal voltage. Steering power low." the stereo would restart nonstop over and over and it wouldn't let me turn it off. Each time there was a restart, the headlights would dim, shut off or go really bright. Also on each restart the steering wheel would lock for about 2-3 seconds. A/c & stereo speakers didn't work at all. After driving for about 20 minutes the engine light turned on and a red steering light with a warning was showing while there was some beeping coming from the dashboard. I didn't feel confident or safe while driving the car but we were in the middle of nowhere at that time and my mom was riding with me. So I drove the car slowly and as safely as possible until I made it home. Once parked at home, I tried to turn the car on and had no luck. Took the car back to the dealership this morning sep 21st 2020, they claim it might be the alternator. A fairly new car with 21,000 miles should not have these issues or burn out 2 batteries.
