Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“While traveling at highway speed without warning vehicle slowed to an idle and would not re-accelerate. Vehicle was towed to an Acura dealer who failed to find a fault. Exact same situation occured the next day on the highway. Only this time I shut off the vehicle for 30 seconds and it restarted and resumed full power. Was able to drive it to an Acura dealer who again could not find a fault on the computer. However, the dealer kept the vehicle and ordered and replace the vehicle fuel pump complete. No issues since.”
NHTSA complaint #11375239, filed 2020-11, 9,500 miles“AcuraLink remote start did not work to start the car this morning or after work but when my wife got home from work the car started about a half hour later by itself in our attached garage with the door closed. It did this twice this evening and once at lunchtime. We will have to keep the car outside until this issue is resolved.”
NHTSA complaint #11566128, filed 2024-01“Upon rapid acceleration, pushing the gas pedal down, the engine light started blinking and the car went into limp mode losing all power. This was a serious concern because we had just got off the interstate and if we had been full speed attempting to pass a vehicle, we could have been in a serious accident due to failure of power.”
NHTSA complaint #11474824, filed 2022-07“I was passing another vehicle around 45mph when I had a loss of power in acceleration. Acceleration was limp went down to 10mph engine light came on. I had to pull off road. Shut car off then restarted. Engine light went off. But acceleration is weak. Unable to maneuver away from an emergency situation if need to. Dangerous to drive it like this. I will take it to dealership but know they' never find any issues!”
