NHTSA complaint #11407494, filed 2021-04, 200 miles“Hi the vehicle shows speed limit of 70 in 25 or 40mph zones. The vehicles system keeps going offline emergency braking and collision. Every time I take to Honda dealer I am being told to go see where the car was purchased and they can't find a issue.”
NHTSA complaint #11397134, filed 2021-02, 380 miles“When coming to a complete atop, the engine switches off (the idle stop function), which is ok, but when I release the brake the engine often fails to restart. I’ve replaced the battery but this appears to be a common problem. It’s been happening more now at the end of summer when it’s hot for some reason. I was told there is a similar investigation open: EA25004”
NHTSA complaint #11757074, filed 2026-08“Can has been making a popping noise that can be felt in the steering wheel for 2 years. Honda has told me nothing was wrong after taking it in 4 times. Now my car keeps stalling at lights, sometimes it takes a while to get it to restart, and they can not figure out why. They keep saying the battery is fine and diagnostics finds nothing.”
NHTSA complaint #11683344, filed 2025-08“I was driving on I-270 highway in active HOV lane and had to stop because of traffic. The car stopped the engine as it usually does by Auto Idle Stop system but failed to start it back when I needed to continue driving. I noticed that the battery light blinked on the dashboard when it tried to re-start the engine. As a result I was in active HOV lane with quickly approaching traffic from behind. We all (me, my wife and 2 kids) were scared. I called 911 immediately for help. This all could end up with a crash and injuries. …”
