My 2018 Toyota CH-R started with a whining noise that sounded like a cat. I didn't get any lights on my dash that could pin point the problem. I took it to the dealership to get it diagnosed and they couldn't tell which part was making the noise. I asked the if they could do a transmission fluid change, and they told me that that type of transmission did not require service. Overtime the noise got worse and louder and a few times while driving in the freeway the car jerked and the RPM gauge drastically moved up and down. I took it to the dealership again and they quoted me $8,000 for a new transmission. At this point I am nervous I will lose power in the middle of the freeway during my daily commute which could cause an accident.

I bought my 2018 CHR in 2017 from Huntersville NC, it has 112,000 miles on it and it is paid off. My CHR has only been serviced at Toyota dealerships and I have all the invoices. On [XXX] Toyota performed the 100,000 mile multi-point inspection and everything was good to go. However, approximately 2 weeks later I started hearing a whining noise. On [XXX] Toyota inspected my vehicle and notified me that the transmission was going bad, and there was no time frame on when the CHR would leave me stranded. Upon my own research the CHR in Canada has issued a 10 year extended warranty due to a faulty bearing in the CVT Transmission; which is the same issue my CHR in North America is having. There has not been an extension on my specific vehicle. I inquired to my local Toyota dealership about Goodwill Assistance and was shut down. The Toyota dealership is only concerned with selling me a different vehicle at this point. I am [XXX] and do not have sufficient income to cover expenses nor a monthly payment. Toyota needs to be held responsible for the same manufacturer defect they recognize in Canada, here in North America as well. It definitely put a sour taste in my mouth about purchasing another Toyota. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The transmission (CVT) in my 2018 Toyota C-HR failed at 101,740 miles, approximately 5,000 miles and 2 months after I purchased the vehicle used. The vehicle began making a whining/rotary noise while driving. I took it to Toyota of Downtown Chicago (RO [XXX], 7/28/2026), where the technician test-drove the vehicle, confirmed the noise originates from the transmission, and recommended full CVT replacement. The quoted repair cost is $14,271.52. The vehicle is currently not being driven and is available for inspection upon request. Safety concern: a CVT that is failing internally can produce unpredictable loss of power, hesitation, or sudden changes in acceleration while driving, which creates a risk of being unable to safely merge, accelerate away from a hazard, or maintain consistent speed in traffic. I have stopped driving the vehicle to avoid this risk. The problem has been confirmed by a Toyota dealership (Toyota of Downtown Chicago), not by an independent shop. The vehicle has not been inspected by the manufacturer's field engineering, police, or insurance representatives. Prior symptoms: the whining/rotary noise was the only symptom I noticed, and it appeared shortly before I brought the vehicle in for inspection. No warning lamps or dashboard messages appeared at any point. I do not know how long the underlying defect was present before I purchased the vehicle, though vehicle history records show the previous owner's independent shop performed a CVT transmission fluid service approximately six weeks before the vehicle was sold at auction. I am aware that Toyota Canada has issued a Warranty Enhancement Program (10 years / 193,000 km) for 2018–2019 Toyota C-HR vehicles covering CVT failures caused by a known defective internal bearing. No equivalent program currently exists in the United States. I am filing this complaint because I believe this same defect affects U.S.-market vehicles and should be investigated.

I started to hear a whining noise under acceleration so I asked Firestone to check it out when I dropped it off for a 100k mile service. They said it was the transmission beginning to fail. I researched online and saw that it is a very common and known problem with the Toyota chr CVT transmission. We went with Toyota because they are known for their reliability and here we are at 102k miles with what is about to become a paperweight that needs a 10-12k repair. That's half the cost of the car itself. At the time we purchased this vehicle new Toyota claimed that this transmission is sealed and maintenance free and the transmission fluid is "lifetime fluid". We have had the car for 8 years, quite short of a lifetime.

The internal transmission bearing defect causes sudden unpredictable loss of propulsion of the vehicle and creates a high risk on the interstate which is where I drive most the time and risks those in my car or around me. The dealer confirmed the issue. There are no warning lights just a whine while driving.

A noise from under the hood kept getting louder. When I took it to the Toyota dealership for inspection, they determined that a bearing in the CVT transmission failed causing the transmission to need total replacement. I can not safely drive my car because the transmission could fail at any time. This issue has been widely reported for the 2018 Toyota C-HR and possibly other year models. There was no warning other than the whining noise that continued to get louder. I was quoted an estimate of $11,868 for repairs.

I own a 2018 Toyota C-HR with approximately 117,600 miles. The vehicle has developed a transmission bearing failure, causing a loud whining/humming noise that increases with vehicle speed. I have been informed that the bearing inside the transmission is failing. This appears to be a premature transmission defect that could affect the safe operation and reliability of the vehicle. I am submitting this complaint because I believe other Toyota C-HR owners may be experiencing similar transmission bearing issues. The vehicle has been maintained regularly, and this type of major transmission failure should not occur under normal use. I request that the federal safety agency investigate potential transmission defects in the 2018 Toyota C-HR.

I noticed a whining sound coming from the vehicle. It would get louder as I accelerated. Took it into a mechanic he drove it, put it on the lift and said the noise was coming from the transmission. I took it to another shop and they quoted me $9,000. For a replacement. This is a problem that Toyota and other manufacturers know about. The CVT is unserviceable.

There was a complete failure of the CVT transmission. It left my daughter completely stranded in a parking lot. The car was inspected at the local Toyota dealership and that is where the transmission failure was confirmed. There were no lamps or messages until my daughter tried to start the car again and every light on the dashboard lit up. Before that, there had been a slight whining sound but we were not sure what was causing it.
