2024 Honda Accord

When driving on highway the car displayed multiple warning messages on dashboard including electronic power system light, lane keeping assist system problem, TPMS system problem, etc. Mileage was 22380miles. I bought the car May 2026. I drove it for around 1000miles. The next day the warnings disapeared.

On 6/19/2026, I had four new tires (Goodyear Eagle Touring, size 235/40R19 96V) and a four-wheel alignment installed at an authorized Honda dealership. The post-service alignment printout showed the right front camber and left front caster remained out of specification both before and after the alignment was performed. I left the dealership at approximately 4:30 PM. At approximately 6:20 PM, while driving westbound on Interstate 10 at highway speed, the left front tire, one of the four tires installed roughly two hours earlier, suddenly blew out with no prior warning light or indication. Notably, the right front tire had triggered a TPMS warning earlier that day, which is what prompted the same-day tire replacement, but it was the left front, which gave no warning at all, that failed. The vehicle was safely maneuvered to the shoulder to avoid a collision with other vehicles. California Highway Patrol responded and later moved the failed tire after it was struck by passing vehicles, creating a hazard for other drivers. The tire itself was not recoverable due to the danger of retrieving debris from live traffic lanes, though photos were taken of the tire and wheel immediately following the incident. The vehicle's onboard tire repair kit could not be used because the vehicle is subject to open NHTSA recall 26V-366, confirmed incomplete on this vehicle. A flatbed tow was required since this model carries no spare tire. I am requesting investigation into whether an installation error (mounting, bead seating, valve stem) or a manufacturing defect contributed to this failure, given the short time between installation and failure.

The engine vibrates/shutters when switching from electric to gas. It almost feels like the engine is going to fall out. I’ve taken it to two different Honda dealerships multiple times and since they can’t duplicate the issue while it’s there then they say there’s nothing they can do. The oil also looks and smells like gas.

The contact owns a 2024 Honda Accord. The contact stated that while driving 50 MPH, the instrument cluster lights illuminated. The message “Emissions System Power Reduced – See Dealer” was displayed. An unknown transmission message was displayed. The engine was not working properly. The message "Pull Over and Turn off Vehicle" was displayed. The contact pulled over for 10 minutes, restarted the vehicle, and continued to drive to the residence. The local dealer was contacted, and a service appointment was scheduled. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 75,000.

The automated braking system engaged unexpectedly for the second time in 3 days. There were no cars in front, no cars parked on the side of the road. The vehicle was brought to a sudden stop with brake flashing on the dashboard. During both instances, there was a car being us that nearly rear ended us due to the unexpected braking.
