NHTSA complaint #11722797

Owner complaint summary

During the summer of 2025, the auto idle engine railed to restart while at a stop light. We had to shut off and restart the car. We took it to the car dealer and they did some sort of software update. It happened again in January 2026 while at a stop light off a highway exit ramp. We took it to a different dealer because we were living in a different city at the time. In their computer system, they could see the repair that had been done. They did some sort of other update and submitted it as a warranty repair for Acura (which the other dealer had not done). They noted there was one other repair that could be done, but Acura would not allow them to do both at once and this update usually fixed it. However, it happened again in February 2026. The engine did not restart from auto idle, this time at a stop light toward the beginning of an eight hour road trip back home. Fortunately, turning off the engine and starting it back up worked. We took it back to the second dealer and they did the additional repair authorized by Acura and submitted as a warranty repair. Three incidents of the auto-idle not restarting the engine in less than a year is not acceptable. The car is unrealiable.
