The contact owns a 2020 Honda Civic. The contact stated that while driving 60 MPH, a bobcat crossed the road, and the bobcat was struck by the vehicle. The contact stated that there was extensive front-end damage and undercarriage damage to the vehicle. The driver’s and passenger’s side air bags did not deploy. The contact was unsure whether there was a warning light illuminated. The contact was not injured. The vehicle was driven to a gas station, inspected, and then driven back to the residence. However, the vehicle failed to accelerate above 40 MPH. The vehicle was taken to a collision center for repair. The contact received a call from the collision center and was informed that all the air bags in the vehicle had been removed and that the wires were cut and twisted together, which led the sensors to believe the air bags were still connected. The vehicle was not repaired due to the cost. The manufacturer was not notified of the failure. The failure mileage was approximately 78,000.

i have experienced multiple issues with the sensors since I've had this vehicle in December 2020. The sensor issues have caused my vehicle to shut down and slowly stop as I was driving on the freeway. The latest incident caused my airbag to deploy without any reason while I was driving slowly in a residential parking lot. It went off in my face and I suffered from hearing problems. I am fortunate that this incident did not harm anyone as it put others at risk from the airbag unexpectedly blocking my view and distracting me from driving. Although the dealership, Tempe Honda, repaired the other sensor issues, they refuse to repair the airbag issue. They are claiming that I need to have my insurance pay for the repair. I have had two mechanics inspect the vehicle and confirm that this is a defective airbag sensor that caused the airbag to deploy. I have not driven the vehicle since this incident as it is unsafe for me to drive. The vehicle is available for inspection at any time. I have contacted Honda on multiple occasions. They have Case #12968314 is my case number and every time that I call, the representative tells me that a Case Manager will call me but I have not received any calls. I also sent an email to Honda on 02 May 2022 detailing this incident that occurred on 14 April 2022.

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 2020 Honda Civic Si verdict →
