There are 2 owner-reported engine complaints for the 2022 Acura MDXin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
The engine suddenly shut off when the vehicle was waiting for traffic light and at full stop. The vehicle would not restart after multiple attempts and had to be towed to dealership. Mechanic at the dealership said the "Idle Stop" feature can drain the battery quickly and had to replace a new battery. We consider this a reportable safety hazard and a potential design defect because 1. The "Idle Stop" feature is turned on by default, though it can be manually turned off. 2. The incident occurred in a very abrupt and unpredictable fashion. The vehicle was started normally about 30-40 minutes before the incidents and has been driven normally in a typical city traffic condition till the incidents occurred. During this period, the computer system did not give off any warning related to a total battery failure.
