What owners say about the engine

Verbatim from NHTSA complaints, newest first
“I brought my car to the dealership Honda North at 382 Newbury Street in Danvers MA on 6/5/25 to repair NHTSA Recall number 23V-858. The vehicle was returned to me on 6/7/25 at which time I was told the interior would have a strong fuel smell for 1-2 days, but that would disappear. After 4 days, the fuel smell worsened and the "Check Engine" light had come on. On 6/11/25 I returned the vehicle to Honda North. When I picked up the vehicle several days later, the fuel odor was minimal, and the check engine light was off. Today [XXX], the check engine light is back on. I plan to call Honda North to schedule what will be my 3rd visit to Honda North for this safety recall repair, which clearly is not being repaired properly, and putting me in further danger of crash or injury.”

“While driving the dash showed a "12 volt battery charging system problem." Continued to drive to a safe location roughly a mile down the road and while enroute all the error lights illuminated and proceeded to state "Tire Pressure Monitor Problem" "Brake System Problem" "Brake Hold System Problem" "Power Steering Problem" and a couple others I don't recall. I lost my power steering while driving and my wipers proceeded to stop working, in a downpour. Contacted AAA who came and ran diagnostics which showed the alternator was dead. I then had to have my vehicle towed instead of driving it to work.”
