3 Blind Spot Detection problem

Failure Date: 03/23/2026

My vehicle started cycling between all of the check engine types of lights to include the emissions system. When taking it to my local Honda dealership, they determined that it was my front camera (multi-purpose camera internal failure). After some research and speaking to the service department, this major safety failure has been happening to many other Honda vehicles. The emissions system failure seems to also be a faulty design. I feel that the camera system failure could have resulted in an accident or major injury. And of no fault of my own. My vehicle is regularly maintained and is merely 6 years old. I should not be replacing a mayor system like the front camera every 6 years.

September 2024, I bought my car to the dealership to check multiple warning lights showed up on my dashboard. The dealer read the code and determine the multipurpose windshield camera had internal malfunction. The dealer told me that my multipurpose windshield camera need to be replace on my 60k mi 2020 Odyssey ex-l for ~$2. 3k in conshohocken PA. I had many of those sensor lights on (e. G. Acc, lane assist, collision mitigation) and saw many comments on a youtube video (Honda Odyssey warning lights bonanza get ready to pay). Do my research online; seem like this happened a lot for the Honda Odyssey from year 2017 to year 2020 hope NHTSA will investigate on this issue.
