Diagnosed (their words) customer states check engine light is on and flashing pulled codes had code p0562 and pOED. traction motor control module system voltage low and HV battery cell voltage sense circuit. went through honda trouble shooting and honda states to replace power control unit (PCU) and battery condition monitor module. test drove vehicle codes came back recommend replacing modules. includes reprogramming. They indicated it is not safe to drive as you may not able to start the car or it can die while running. This was at out of state and have to repair without options and get a rental car for a week.

Reached out to Honda Corporate before Christmas and they declined good will reimbursement request.”

“Software problems causing the backup camera to become disabled and the driver to lose their rear visibility. The screen is completely blackened. This occurred without warning. One day it just went dark. On other note - I do not have access to any information appearing on the screen at all. Very inconvenient and frustrating.”

“My 2020 CR-v hybrid has suddenly lost power on the freeway a total of 4 times in the 6 years I've owned it. It is always at freeway speeds. The flashing engine light appears and the car loses power. After pulling over, turning off the car, and waiting a few minutes, the car can be turned on and driven with no more flashing engine light and no more problems for months. Each time I've taken it to the dealer and each time they haven't been able to replicate or find the problem. I've been told that error codes were not generated. I purchased my car new in July 2020, and the power-loss incidents were: - Fall 2020 - Summer 2022 - December 2024 - June 2026 A google search shows that many other crv hybrid owner have experienced the same problem, and also have had service technicians unable to find problem. This is a major safety concern.”

“In November 2025 a new transmission was installed Curry Honda in Atlanta GA on my 2020 Honda CR-V. The new transmission came with a 3 year/36,000 mile warranty. In March 2026 my vehicle broke down and was towed to Tameron Honda in Daphne Al where a speed sensor was replaced at my expense of 388.44. The adaptive cruise control was not working prior to this repair. Within two weeks the vehicle experienced further issues and had to be driven in a compromised condition back to Curry Honda in Atlanta where the transmission wire harness was diagnosed as corroded and replaced at a cost of 1696.99. My vehicle has been garage-kept its entire life except when in the care of a dealership. Corrosion on a recently replaced transmission in a garage-kept vehicle cannot be attributed to environmental exposure or owner neglect. It points directly to a defective part of improper installation at Curry Honda. These failures occurred within months of a new transmission installation with no prior history of issues. I believe this is a safety defect as the vehicle broke down unexpectedly and had to be driven in a compromised condition posing a safety risk.”
