Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“Car was parked outside during summer heatwave. Interior was hot. Vehicle started with hesitation, ran for a moment, and then stalled and failed to start in the middle of a busy intersection. Crank, no start, was the final symptom. Occupants were nearly hit by a medium duty truck who had trouble stopping. After the car was hauled to a shady location, the interior cooled and it again started. Since that sentinel event, the car stalled or failed to start 3-4 times-- each time after being parked in the sun. Traced problem to a failed solder joint in the pgm-fi main relay under the dash. …”

“Acura says they guarantee all parts of the safety belt for the use of a lifetime of the car. Car has 120000 miles on it. I have intermittent buckling issues and srs airbag switch is bad inside a sealed safety belt. Could easily be remedied if it wasn't a sealed unit. They say they won't fix it because it's a canadian car even though it's spent 100% of its owned life in the united states. They want an excessive amount of money, over $400 to fix it. …”

NHTSA complaint #11267092, filed 2019-10

“There is a major issue with the relay under the steering wheel blocking the fuel from the pump going to the engine. This also affects the security system as well as the rack and pinion. The vehicle security turns itself on and off as it pleases, often leaving driver/passengers stranded and sometimes with the alarm not shutting off. This is after having keys re-programmed and most parts replaced for a hefty price tag. Due to this, the vehicle will only start at times. I've seen several similar complaints and taken it to many costly mechanics. …”
