am filing this complaint regarding a transmission failure in my 2018 Toyota C-HR that left me stranded on the freeway and created a serious safety hazard. The vehicle experienced a transmission-related failure that caused it to lose its ability to operate properly while I was driving. As a result, I was left stranded on the freeway, exposed to passing traffic and at risk of being involved in a collision. A vehicle losing its ability to maintain normal operation on a busy freeway can create a dangerous situation for both the driver and other motorists. I am concerned that this transmission failure may represent a safety-related defect that could affect other owners of 2018 Toyota C-HR vehicles. A transmission should not fail in a manner that leaves a driver unexpectedly stranded in an active traffic environment. I request that the federal safety agency investigate whether transmission or continuously variable transmission (CVT) defects in the 2018 Toyota C-HR could cause sudden loss of power, loss of drive, or other dangerous failures while the vehicle is being operated. I believe this incident deserves attention because of the potential for serious injury or a collision. I am submitting this complaint so the incident can be documented and considered as part of any investigation into similar complaints involving this vehicle. I respectfully request that the federal safety agency review this incident and determine whether further investigation or corrective action is warranted. Thank you for your attention to this vehicle safety concern.

Unknown, ​I recently received a Customer Support Program notice from Toyota regarding a known transmission noise affecting certain 2018 Toyota C-HR vehicles. My vehicle exhibits the exact symptoms described in the bulletin—specifically, a small plane-like engine sound when driving between 20 and 40 mph. ​On XXX, I brought my vehicle to Toyota of [XXX] for diagnosis and service under this program. However, the dealership returned the vehicle without performing any repairs, claiming that it is outside the program's coverage. Given that my vehicle's symptoms directly match the documented defect covered by Toyota's customer support initiative, I am requesting a re-evaluation of my vehicle's eligibility and a resolution to this transmission issue. P.S. I escalated this to Toyota Headquarters and I received same denial response. I replied As many owners on public forums and social media have noted, CVT reliability concerns are a well-documented challenge for this model. Given Toyota’s strong reputation for long-lasting vehicles, I was surprised to find that my specific serial number is currently excluded from your service program. Could you please clarify if Toyota will reimburse the costs if I have this repair performed by a private mechanic, as indicated at the bottom of your recent letter? I am currently documenting all related records for my files. My response was ignored. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Car began making a grinding sound while driving on an expressway. From that point on, could no longer reach a speed above 30 MPH. Independent Mechanic diagnosed an issue with CVT. Car was inoperable and sat in my driveway for 8+ months as we tried getting Toyota to respond to calls and email. Received a CUSTOMER SUPPORT PROGRAM 26TE06 letter from Toyota on 12Sep2026 explaining that they would provide coverage for the repair. Had the car towed to O'Brien Toyota in Indianapolis. Dealer said that the car would not be covered because they had received a REVISED letter from Toyota that only covered a specific range of CVT serial numbers and while the CVT malfunction, model and year of my car qualified.....my car did not have a CVT serial number in that range and NO REPAIRS WOULD BE MADE! Called the Toyota Brand engagement number and they confirmed that Toyota would not cover the CVT in that range and provided me with a case#: 260922002588.

Isolated noise to transaxle internal.Technician determined transmission failure (torque converter) and recommended replacement. Afterwards, while driving home and waiting at a red light, vehicle did not accelerate when light turned green. I put the car into park, then back into drive. No movement. Switched to manual mode, no movement. Went back to automatic and car started to go. Felt that the transmission was slipping. I was afraid that it was going to stall out again, so I ran the next light to get onto to the freeway to get my vehicle home ASAP. I will never drive another vehicle with a CVT transmission. If I would have known about any issues with CVT’s, I would NOT have purchased this vehicle.

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.
