NHTSA complaint #11712781

Owner complaint summary

The following issues occur on a 2020 Acura MDX with low 50k miles, maintenance was done regular whenever a maintenance schedule appear. For the past few years after purchasing the vehicle we started getting a non-start engine with the key fobs and automatic side mirrors did not open or close when parked. Brand new batteries were replace for the key fob and later the Car Battery and the issue occurs intermittently, this was brought to the attention of the dealership and each time (documented) that they were not able to reproduce when they turned off the vehicle, this was mid 2024 06-13-2024 and sporadically continues till this year 2026. The dealership did not test or trace the electrical system as they were told to reproduce the issue first as it will happen at that moment. A new recent event 2025 has also occur and was brought to the dealerships attention, a warning message indicating - Electric Parking Brake Problem follow by a Emissions System Problem will appear. This was also "reset" by the dealership and indicated it was safe to drive but event reoccurs every few months. A 2nd opinion to another mechanic indicated it can be the emergency brake system to be faulty and driving the vehicle when the message appears may cause an immediate stop, advised us to have the dealership reach out to the manufacture. No word from either for the past year. Any open recall for my VIN was done once we were notified and a New Car Battery replaced and new batteries in key fobs - issue continues. Please assist Thank you
