2018 Toyota C-HR

My 2018 Toyota CHR started making a whining noise which I initially thought was a wheel bearing but was later confirmed to be a transmission problem. The mileage was 62, 871, but as I stated earlier it could have been earlier because I thought the initial noise was a wheel bearing. I took the Toyota CHR to the Toyota dealership on 10/14/25 at which time they determine the transmission was bad and had a cost of $12,369.64 to replace. The car did not have any indication or any warning lamps of the problem.

I can hear a whirling sound coming from under the car. I took it to the mechanic and was told the transmission is failing and need replacement. I was told by At a Toyota dealership there is no maintenance on this transmission. It doesn’t even have a dipstick to check levels. The whole design is to replace rather than maintain. My car had 80k miles when it started

My transmission has started slipping and making weird noises. I'm afraid it will fail while driving and cause an accident. I just recently went to toyota and they told me it needs to be replaced. There have been 200+ complaints on the toyota chr for transmission issues, but no recalls for the 2018 model, which apparently has the most issues. There have been no warning lights to appear since owning the vehicle in 2021

The contact owns a 2018 Toyota C-HR. The contact stated that while driving at 30 MPH, there was an abnormal grinding sound coming from the transmission. No warning light was illuminated. A dealer was contacted. The vehicle was taken to the dealer where it was diagnosed, and determined that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and denied a claim from the owner. The approximate failure mileage was 75,000.

At approx 110K miles, I noticed the CVT transmission whining during acceleration - w/ the whining noise increasing/decreasing as I accelerated/decelerated. As the whining increased over the ensuing miles, during my 120K service, I asked the dealer to evaluate its cause - and was advised that my transmission is failing and that I need a new one. Estimated cost: $12K. Yes, trans is available for inspection upon request. Obviously, should the trans fail while the vehicle's being operated, it could leave the driver (me) stranded or worse. Trans has only been evaluated by the dealer's service tech(s). No warning lamps or other indicia that trans is failing has appeared. In addition, I've noticed no performance issues/differences - w/ the only symptom to this point being the loud whining as I accelerate.

I have a 2018 Toyota C-HR. I fully paid it off several years ago. I’ve noticed a low whirring noise a few times and after maintenance checks they’ve gone away. It started probably around 45/50k miles but around 80k the noise gradually got louder. At my 90k inspection Toyota told me that the noise what coming from my transmission and they didn’t want to complete the transmission flush due to the issue. They said I needed to replace the transmission and it would cost roughly $10k. The service provider said he could refer me to an auto body shop down the street but it would still be between $6-8k for a used transmission. He also told me my car is still drivable but he recommended I get it replaced as soon as possible. I paid the car off fully trusting Toyota’s reliability. I’m not even at 100k miles and the car is failing me.
