2018 Toyota C-HR: hesitation when accelerating

Filed Aug 9, 2026 · Transmission · IL

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.

Transmission internally failed. This has been confirmed through multiple sources. Dealership, mechanic. No warning lights, grinding noise. My safety is put at risk because A failing transmission creates multiple safety hazards while driving. The vehicle may lose power unexpectedly, hesitate, or fail to accelerate when needed, especially during turns, intersections, or highway merging. It can also shift unpredictably or refuse to shift, causing sudden jerking, surging, or deceleration that increases the risk of losing control. Transmission failure can lead to total loss of propulsion in traffic, leaving the vehicle stalled in dangerous locations. Additionally, fluid leaks and overheating pose fire risks. Overall, the unpredictable operation of a failing transmission significantly increases the likelihood of collisions and unsafe driving situations.

The transmission on my 2018 Toyota C-HR has been malfunctioning, and there is a noticeable grinding or rattling noise coming from the front end while driving. The issue occurs consistently during driving. This problem puts my safety at risk because the vehicle hesitates to accelerate properly, and the noise suggests a potential mechanical failure that could lead to loss of control while driving. The issue has not yet been officially confirmed by the Toyota dealer, but I plan to have it inspected. The vehicle is available for inspection upon request. The problem started around 67,000 mileages in October, and there were no warning lights or dashboard messages before the issue began. The noise has gradually worsened over time.

I am reporting repeated transmission failures and unsafe driving behavior in my 2018 Toyota C-HR. The transmission was first replaced at approximately 89,000 miles under an extended warranty due to whining noises and slipping. Since then, I have returned to the dealership three separate times with the same symptoms. The dealer acknowledges the issue but has not performed any corrective repairs. The vehicle now exhibits the same failure symptoms again at 124,000 miles. These include whining noises when accelerating, hesitation to engage, and intermittent loss of power. This creates unsafe driving conditions, especially when merging or crossing intersections. Details and Pattern: Toyota Canada has publicly acknowledged a faulty bearing inside the CVT transmission for the 2018–2019 Toyota C-HR and extended the warranty to 10 years / 193,000 km. My vehicle has the same CVT transmission (K114) and was built in the same factory (Turkey). Toyota USA has not offered any comparable warranty extension or recall, despite identical vehicles experiencing the same failures. Numerous other U.S. owners have reported similar CVT failures to the federal safety agency and CarComplaints.com. This appears to be a widespread safety defect related to the transmission’s internal bearing or CVT assembly, which can cause loss of power and control while driving. Requested Action: I request that the federal safety agency investigate the 2018 Toyota C-HR CVT transmission for design or manufacturing defects, including bearing failure, and determine whether a U.S. recall or extended warranty campaign should be issued as Toyota Canada has already done.

Toyota ch r I noticed hesitation when starting the engine about 3 days prior. Two days ago the car would not start. I called road side assistance. I was given a jump. 8 hours later I needed another jump. The car turned on and but shortly afterwards the parking break and lights began flashing on the control panel. The car could not be pushed. It was not accelerate nor reverse. Car was towed to the dealer. The dealer states the battery was not jumped correctly and the control panel may need to be replaced. I asked for the warranty to cover the diagnosis, because this car should have control panel protection to avoid major issues. This car is poorly designed. It should be stated on the battery not jump the car and inform me all the damage this could create. However the car was not jumped incorrectly. The dealer showed me acid around the battery but never showed me the control panel damage. Why is there a battery and a control panel issue on a car that is new. Why does the diagnostic cost $280. Headquarters was contacted. But no resolution
