Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2021 C-HR vehicles. The radar sensor may not have been activated during production, making the pre-collision system (PCS) inoperative.
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
“I have a very loud whine coming from the front of my 2021 Toyota CHR with 93,000 miles. At first I thought it was a wheel bearing so I replaced it but the noise did not change. Over the last few days it has become louder and louder. Now every once in a while the car feels like it almost slips then catches traction. The noise has been confirmed by an independent shop, who said there is a new TSB (T-SB-0048-26) for the transmission which they said matches everything they noticed with my vehicle but it was only for 2018-2019. No warning lights or anything has appeared.”
“The contact owns a 2021 Toyota C-HR. The contact stated that while driving at an undisclosed speed, several unknown warning lights were illuminated. Additionally, the message "Service Vehicle Now" was displayed. The vehicle was taken to an independent mechanic, who was unable to determine the cause of the failure. The vehicle was not repaired. The manufacturer was notified of the failure but provided no assistance. The failure mileage was 82,000.”
“On May 26, 2026 I was driving on the highway at around 50mph and the vehicle swerved to the right on its own causing me to swerve back and forth between two lanes for about 10 seconds. The wheel moved on its own causing me to use force to try to get the car back in control. Thankfully no one was next to me but if that had not been the case, it would have a caused a serious and life threatening accident. Had I been going any faster or on the regular streets, I am certain the vehicle would have flipped or ran off the road. It was EXTREMELY scary, especially as I am a mother and my baby is frequently in the car. I have contacted two separate Toyota dealerships neither one of them giving any concern to my safety or well-being and are charging me $100+ to run a diagnostics. I no longer feel safe driving this vehicle, I no longer believe that Toyota cares about their clients and will no longer be recommending Toyota for their lack of concern of their drivers safety. There were no warning messages or notifications before, during, or after the incident.”
