Hello, the car has this issue since i got it nrand new. Every time i drive in the rain or while its snowing, all lights on the dash board comes up and at least 50% of the options gets disabled. Like back up camera, windshield vipers, horn beeps non stop until you disconnect the battery and more. I see there is lots of people reporting same issue but honda dont want to help me with this issue. Went to homda dealer and they said $169 for diagnostics, then called and said its gonna be 2 hours which is $338 and even then saying they are not sure if it will take them 2hrs or 10 and i had no choice to tell them to stop and pay only $169. Please see the video for details Honda case# 13733111 https://youtu.be/ABoYlunVNVo

Feb 17, 2023Electrical systemDriver assistance

I was driving my 21 Honda Accord 1.5T on the highway and all of a sudden vehicle lost the power and Honda sensing / Emission warning lights came on. It almost cause a major accident and I was lucky enough to exit the freeway without incident. I drove to the Honda dealer and they found out one of the wire harnesses was chewed by a rodent which causes the whole issue. I did some research and found out that Honda was using less expensive Soybean base wire harnesses (instead of Petroleum base wire harnesses) to save the planet earth. This Soybean wires are easy target for rodents. This less expensive Soybean wire harness cost about $3000-3500 to replace and it's NOT fair to the consumer. Honda must re-call this Soybean wire harness before causing some major accident, especially on the freeway ( imaging your car losing power while driving 65-70 mph)

I was with my family taking the on ramp to the Long Island expressway, when suddenly the rear wheels locked up and the parking brake was engaged. I hit the brakes. And as fast as it happened is as fast as it resolved. Scared all of us and almost got hit from the car behind us.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2021 Honda Accord Fhev verdict →
