2019 Acura MDX Electrical System

Electric Parking Brake Problem and Emission System Problem lights came on spontaneously

Infotainment system randomly becomes unresponsive and the screens will go black. The dealership stated that my phone was causing the issue. This is not true as the issue has happened when my phone is not in the car, phone is in the car/connected via bluetooth, in the car/connected via apple carplay (wired connection). This could be dangerous during the summer as these screens control the temperature controls and some of the safety systems.

The contact owns a 2019 Acura MDX. The contact stated that upon locking the doors with the key fob, the vehicle would remain unlocked. Due to the failure, the contact believed that someone entered the vehicle and changed certain setting from the original setting. The contact was informed by the dealer that the setting change should not have shown on the multi-information display (MID) screen. The manufacturer was notified of the failure. The vehicle was not diagnosed or repaired for the failure. The failure mileage was approximately 40,400.

While in traffic the auto start sometimes fails to engage and the car stalls. Battery lights come on and the car goes into neutral on its own. I have to sit there and wait about 5 minutes in traffic before it restarts. Battery checked out fine. It has happened 3 times now. This is dangerous, and can/will cause a collision.

When the idle stop comes on it shifts the car to neutral and I must shut off the car to get it to start again. This happens while on the highway and is unsafe.

The contact owns a 2019 Acura MDX. The contact stated while at a stop light and attempting to make a left turn, the vehicle lost motive power and stalled. The contact stated that a warning message to "Park and Restart” the vehicle was displayed. The contact shifted the vehicle into park(P) and attempted to restart the vehicle however, the vehicle would not start immediately. The contact stated that after several attempts the vehicle restarted. The vehicle was taken to the dealer and the contact was informed that the brake assist feature had drained the battery. The contact was informed that the battery needed to be replaced. The manufacturer was not contacted. The failure mileage was 32,000.

When stopped at a light or in traffic the vehicle engages the auto idle feature. (turns off the engine to save gas). Upon releasing the brake, the car should re-start, instead the car does not start. The car jumps out of the drive gear into neutral on the transmission. The electrical system goes crazy and does not allow you to either turn off the car's electrical system or re-restart the car using the car's on/off button. This has happened to me at least 5-10 times over the last year. Each time the car becomes immobile in the middle of the road or highway for up to 2 minutes, until the electrical system resets and allows you to turn off all the power and re-start the car. It's a very scary and dangerous situation, when my vehicle is stranded in the middle of a highway or a road for up to 2 minutes, as traffic tries to avoid crashing into my vehicle. Searching online, I was able to see that this same condition has affected many MDX owners but Honda does not seem to have recall or fix for this issue.

The contact owns a 2019 Acura MDX. The contact referenced NHTSA Campaign Number: 21V215000 (Fuel System, Gasoline). The contact stated that after refueling the vehicle and driving several miles, the fuel gauge fluctuated to empty. The contact stated that the fuel gauge would indicate the incorrect amount of the fuel in t fuel tank. No warning light was illuminated. The vehicle was taken to the dealer where the failure could not be duplicated. The manufacturer was notified of the failure and the contact was informed that there was no recall on the VIN, and transferred the contact to the NHTSA Hotline. The failure mileage was approximately 44,000.

WHILE DRIVING AT HIGHWAY SPEED, THERE WAS SINGLE "POP" SOUND THAT SEEMED TO COME FROM INSIDE THE DASHBOARD BETWEEN THE ON DEMAND MULTIFUNCTION DISPLAY (ODMD) AND THE INSTRUMENT PANEL. THE NAVI SCREEN THEN BECAME SOLID BLACK. AFTER A VERY SHORT TIME AND WHILE STILL AT HIGHWAY SPEED, THE NAVI SCREEN BRIEFLY SHOWED THE VIEW FROM THE BACKUP CAMERA. AFTER A FEW SECONDS BOTH THE NAVI SCREEN AND THE ODMD SCREEN BECAME SOLID BLACK AND REMAINED THAT WAY. THEN, WITHIN SECONDS, LIGHT COLORED, GRAYISH SMOKE BEGAN FLOWING OUT INTO THE VEHICLE FROM THE CD SLOT ON THE ODMD. IMMEDIATELY, THERE WAS AN ODOR IN THE CAR LIKE THAT FROM BURNING PLASTIC OR ELECTRICAL INSULATION. AS SOON AS POSSIBLE THE CAR WAS PULLED OFF THE HIGHWAY AND THE ENGINE WAS TURNED OFF. THE SMOKE CONTINUED TO COME OUT OF THE CD SLOT UNTIL THE ENGINE WAS TURNED OFF, THEN THE SMOKE STOPPED COMING OUT. AFTER SEVERAL MINUTES THE ENGINE WAS RESTARTED AND THE CAR WAS DRIVEN TO A SAFER LOCATION.THERE WAS NO SMOKE COMING FROM THE CD SLOT AFTER THE CAR WAS RESTARTED AND WHILE DRIVING THE CAR TO THE DEALERSHIP FOR SERVICE THE NEXT DAY. AN ODOR LIKE THAT FROM AN ELECTRICAL FIRE REMAINED NOTICEABLE IN THE VEHICLE. PRIOR TO THE EVENT, THE DRIVER OBSERVED NO VEHICLE WARNING INDICATIONS, AND BOTH THE NAVI AND THE ODMD APPEARED TO BE FUNCTIONING NORMALLY. THE CD PLAYER WAS NOT BEING USED. THE DEALERSHIP SERVICE MANAGER ADVISED ME THAT THEY CONSULTED WITH ACURA ENGINEERING PERSONNEL, INSPECTED AND TESTED WIRING INSIDE THE DASHBOARD AND HAVE ISOLATED THE CAUSE OF THE PROBLEM TO "A SHORT IN THE RADIO." THE DEALER SAYS THAT THE ODMD AND THE HARD DISK DRIVE HAVE BEEN SENT TO ALPINE TO DETERMINE THE CAUSE OF FAILURE AT ALPINE'S REQUEST. I HAVE ASKED THE DEALERSHIP TO CONFIRM THAT THE REPAIRS TO THE VEHICLE WILL ENSURE THAT THIS KIND OF EVENT WILL NOT RECUR.
