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.

What owners say
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.
Transmission – Loss of Power / Jerking / Safety Hazard The vehicle is experiencing a serious issue with the K113 CVT transmission. The transmission produces abnormal noise and can jerk and lose power, creating a potentially hazardous condition, particularly when accelerating to overtake another vehicle or when merging onto a freeway. A sudden loss of power in these situations can significantly increase the risk of a collision. The vehicle has been properly maintained and driven normally. The transmission issue appears consistent with a known problem reported with this CVT/transmission design. I am concerned that the underlying manufacturing/design issue may cause premature transmission failure and create an unsafe driving condition. The vehicle currently has approximately 107,000 miles. Despite the issue, the vehicle may continue to operate and shift, making the problem difficult to identify until the transmission is under load or has been driven for some time. I am requesting that the federal safety agency investigate this transmission issue and determine whether a safety defect or manufacturing/design defect exists and whether additional action by the manufacturer is warranted.
While driving, my 2020 Toyota C-HR suddenly lost acceleration in the middle of the road, with the vehicle failing to respond to throttle input. This has now happened twice. There was no warning noise (no whining or grinding) beforehand, and the loss of power occurred without warning while the vehicle was in motion, creating a dangerous driving condition due to inability to maintain speed or safely merge/clear traffic.
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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
There was a loss of power while driving. As I pressed on the gas, the engine would rev, but the vehicle would not accelerate. This is a major safety risk.
I am experiencing a severe and hazardous failure of the Continuously Variable Transmission (CVT) bearing. While driving, the vehicle produces a loud, persistent humming noise that increases in volume with higher RPMs. A failure of this nature leads to a complete loss of propulsion while in motion, creating a critical safety hazard and a high risk of high-speed rear-end collisions. The vehicle has been officially inspected twice confirming the CVT bearing failure. It’s being recall in Canada but not the USA Toyota has refused the usa market for any help. American drivers are left operating vehicles with a known, unaddressed safety defect that can cause sudden power loss at highway speeds.
I experienced a sudden transmission failure on roadway. This is a severe safety hazard. I lost all powertrain to my car while in motion. I had to coast the car onto side road at 4am on 6-15-26. Upon further investigation this car year 2018, make toyota and model ch-r, has premature K114 CVT transmission.
The CVT transmission failed at approximately 60,000 miles. The vehicle was fully maintained by Toyota dealerships. The failure of the transmission bearing will cause the car to lose power and could fail while driving, creating a risk of being stranded in traffic or being unable to accelerate to avoid a collision. Toyota Canada has extended the warranty for this same transmission issue up to 119,924 Miles (193,000 KM) and 10 years on comparable Toyota C-HR vehicles, but Toyota USA has refused to provide the same coverage.” See comments at Toyota Forum [XXX] Please see below Toyota Canada announcement: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
Vehicle: 2018 Toyota C-HR (Base Model) Issue: CVT Transmission Failure I am submitting this complaint regarding a serious defect in the CVT transmission of my 2018 Toyota C-HR. After owning it less than 2 years, the vehicle developed transmission problems that rendered it unsafe and ultimately undrivable. Multiple mechanics, including a dealership and a transmission specialist, confirmed the issue originates where the transmission meets the axle on the driver’s side. The recommended solution was a full transmission replacement, with repair costs quoted as high as $11,000, nearly equal to the car’s entire market value. The vehicle is available for inspection upon request. There were no warning messages or lamps to indicate an issue prior to the incident that occurred. This situation raises serious safety concerns: The transmission failure occurred suddenly, leaving me unable to operate the vehicle. I was on the way home during rush hour traffic. I approached a redlight and came to a stop. Once the light turned green, my car wouldn't accelerate and began rolling backwards any time I attempted to accelerate. A transmission defect can cause unexpected loss of power or drivability, putting myself, drivers nearby and passengers at risk on the road. The fact that this issue is widely reported among Toyota owners suggests a systemic defect that compromises public safety. Customers are forced to choose between paying exorbitant repair costs or continuing to make loan payments on a car they cannot drive. Toyota has long been viewed as a trusted brand known for reliability, yet this defect undermines that reputation and leaves loyal customers feeling misled. I respectfully urge the federal safety agency to investigate this issue and Toyota to issue a recall or extended warranty coverage for affected CVT transmissions. Customers should not be left with unsafe, undrivable vehicles and repair costs that exceed the cars value. This is not only a matter of fairness but of public safety.
