don’t have the exact locations,date or time but this has happened around 5 times where I am driving and comes to a come a complete stop and my engine wouldn’t start,I had to put on my hazard lights turn off the vehicle then restart it

Brakes were being applied when no cars were around me. Now, 5 warnings were given to me as I drove down the highway. The warnings were as follows: Adaptive Cruise Control Problem Collision Mitigation System Problem Road Departure Mitigation System Problem Lane Keeping Assist ProblemAuto High-Beam Problem Brake System Light

Engine failed and now the piston rod is knocking inside the engine. Engine failure while operating a vehicle is extremely dangerous and could cause an accident or death to myself and anyone else around my vehicle while its being operated. This type of issue can even cause a fire in the engine bay. When the issue presented itself I was going 60 down the highway. Yes, the vehicle has been in two independent shops which have both confirmed the engine failure due to premature connecting rod bearing wear which was most likely caused by manufacturer crankshaft issues. No it has not been inspected by manufacturer, police, insurance, or others. No there were not any warning lights, messages, or sysmptoms prior to the failure.

Car shuts down and does not restart. Also goes to neutral and does not allow car to be steered. Also seems to be related to auto restart.

Was at a red light and the car just shut off. NOTHING! After about 5-10 seconds I pushed the start stop button and it hesitated for a few seconds and I let go and then tried it again. It hesitated and then came on. No problem the rest of the day. I have had the car for a year and zeo issues with the. My Mother had it for 3 years previously and she never had the issue. The battery is good (and only 1 year old) because I put it on my tester a few months ago. 70,000 miles. I looked up the symptoms and found that this has been an on going issue for a few years. NOT NEW. I reached out to Honda and they said I have to have it diagnosed and pay for it.

At approx. 5 years of age & 67,500 miles, the engine began to make rattling or ticking noises that were in sync with engine speed (RPM). Within 1 day of noting the noise, I took the first available appointment to bring the vehicle to my local Honda dealership, Napleton Honda in Loves Park, IL. Napleton Honda diagnosed the issue as "rod knock" due to failing connecting rod bearings. The dealership advised that the only recourse is to replace the engine. Honda Motor Corp (manufacturer) was notified by me about the issue, but they declined to make any substantive effort to assist with the repair costs despite the fact that the issue is increasingly known and documented as per NHTSA campaign # RQ24013

Fuel pump failure mid-traffic in busy two lane road, unable to start vehicle. The engine sputtered and then halted with all warning lights on dashboard lighting up. Full propulsion of the vehicle ceased while in traffic causing car to be dead on the side of the road until police and tow truck could be dispatched. If this occurred on a busier road or in a 65 mile per hour divided highway, this could have caused a major mukti-vehicle accident and placed me in significant danger.

The brake system is not working properly when stopped on a hill. The vehicle will roll backwards after pushing the brake. If you are stopped on a hill you have to keep the brake engaged while also accelerating to keep from rolling backwards and hitting the car behind you.
