When owners complained

A spike years after the car went on sale usually means a part wearing out on schedule across the whole fleet — the kind of pattern no single owner can see from inside their own car.

ON THE AFTERNOON OF MAY 11, 2011 I PUSHED THE BUTTON TO CLOSE MY CAR TRUNK HATCH AND MY 13 Y/O DAUGHTER RAN INTO A SHARP EDGE OF THE HATCH CUTTING HER FRONT RIGHT EYE LASH. THERE IS A MANUFACTURER-BUILT SHARP EDGE THAT CAUSED THE CUT. SHOULD THE EDGE HADN'T BEEN IN THAT LOCATION, SHE WOULDN'T HAVE CUT HER EYE LID. WE IMMEDIATELY TOOK MY DAUGHTER TO THE HOSPITAL EMERGENCY ROOM TO STOP THE BLEEDING AND RESEAL HER EYE LID.

IN MY CASE, I OPENED THE REAR DOOR, BUT WHEN I WENT TO GET SOMETHING FROM THE BACK OF THE VEHICLE, THE DOOR CAME DOWN ON MY HEAD. NOT ONLY IS THIS DISAPPOINTING TO HAVE THIS ISSUE IN A CAR WITH LESS THAN 40,000 MILES, BUT IT IS ALSO VERY DANGEROUS.

WHILE PARKING, THE CAR SUDDENLY ACCELERATED AS IF THE ACCELERATOR WAS FLOORED, AND THE CAR ONLY CAME TO A STOP AFTER HITTING A BLOCK WALL. THE ENGINE CONTINUED TO REV UNTIL THE CAR WAS PUT INTO PARK AND THE ENGINE TURNED OFF. I COULD HEAR THE TIRE SCREECHING LIKE "BURNING RUBBER" WHEN IT ACCELERATED. PRIOR TO THIS INCIDENT, I'VE BEEN EXPERIENCING THE CAR LURCH FORWARD WHILE DRIVING FOR THE PAST 2 WEEKS. BUT IT WAS HARD TO REPRODUCE, AND I WAS IN THE PROCESS OF TRYING TO FIGURE OUT WHEN AND HOW IT HAPPENS.

UNKNOWN OR OTHER

The hazard warning switch on my 2011 Acura MDX Technology & Entertainment Package VIN [XXX] sticks. It is due to a manufacturing defect and not because of normal wear and tear. That is a safety concern because when it is pressed and sticks, such as when giving the right of way to an emergency vehicle, or in bad weather, it not possible to make it unstuck while driving, and requires a screwdriver to pry it back to unstuck position, and if that option is not available then the stuck hazard switch will drain the battery when the vehicle is shut down. Please refer to enclosed Acura ServiceNews Article B15070C. On 8/9/2025, for my service at Hendrick Acura, I requested this known safety issue be fixed. I demonstrated by pressing the hazard switch that got stuck and required a screwdriver to unstick it. But the dealer unreasonably wanted me to pay $99 diagnostic fee to troubleshoot an obvious issue and even when I showed them the Acura ServiceNews Article B15070C. So, I was forced to confirm the issue indirectly myself. On 8/11/2025, I ordered a replacement hazard switch part number 33510-STX-A02 from another Acura dealer Contemporary Cars, for $37.02, per enclosed, even though it was a waste of my money. I swapped out the hazard switch and as expected it still got stuck. I have enclosed two pictures of my DIY diagnostic. I then searched for replacement dashboard center panel online from the Acura dealers, but I am unable to find any available. I then contacted Acura Client Relations on 8/25/2025, and they opened a Case # [XXX]. Kevin from Acura Client Relations called and stated that B15070C does not apply to my VIN. But I disagree because B15070C states for 'Affected Vehicles' - "2010-13 MDX (All trim levels except base." Hence, I am contacting NHTSA to ask Acura to cover my VIN as a saftey recall, and either provide me a replacement center panel that does not have the same manufacturing defect, or ask Hendrick Acura to replace it free of cost. Thank you. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION A

Engine excessively consumes oil. No issue to the engine whatsoever no smoke at exhaust no burning oil. Check my oil after about 1000 miles and I’m missing a quart of oil. There was once a recall for this issue but the window to get repaired has expired. That does help people that purchased this car after the window. Issue need to be a permanent recall and not a temporary.

Moonroof / Sunroof glass spontaneously exploded as while driving on Interstate at approximately 65mph. This caused many small peices of glass to break inward some of which entered into the cabin and onto passengers including the driver. The glass exploding was very loud and caused me to jerk my steering wheel. It scared the passenger as well. Also small slivers of glass can be felt in the skin.

This car burns oil at an insane rate. I have to go to Jiffy Lube after only 1500 miles, and they are in shock when they top me off each time. Two of the employees have said that my engine is at trial of exploding because this car burns through oil so fast. Your website says that there is no recall, but there actually WAS a recall for this car, but I was NEVER NOTIFIED about this dangerous issue. Acura refuses to honor the recall because they say the window to get the car fixed has expired. This is ridiculous and unsafe.

Excessive oil consumption. I have the oil changed when the maintenance minder gets to 10%. Usually this is about 5,000 miles between oil changes. I will add oil to the engine at 50% oil life or 2,500 miles. I have contacted Acura and they are unwilling to address this problem. These engines need to be recalled. This is a reoccurring event.

I HAVE A 2011 ACURA MDX AND JUST RECENTLY MY AIRBAG SRS LIGHT HAS CAME ON WHEN I TURNED MY VEHICLE ON. I WAS TOLD BY THE ACURA DEALERSHIP THAT THIS WAS DUE TO A MALFUNCTIONING AIRBAG SENSOR. DUE TO THIS MALFUNCTION NONE OF MY AIRBAGS WILL DEPLOY IF I WERE TO GET INTO AN ACCIDENT. WHICH I THINK IS ABSOLUTELY INSANE. WHEN I TOOK IT TO THE DEALER THEY STATED IT WOULD COST OVER $1500 TO FIX IT. AS A SINGLE MOTHER I AM NOT ABLE TO AFFORD TO HAVE THIS ISSUE FIXED. I CALLED ACURA AND THE LADY I SPOKE TOO WAS VERY RUDE AND SAID THAT THERE WAS NOT ANY RECALLS REGARDING THIS ISSUE AND THAT ACURA WOULD NOT HELP WITH THE REPAIRS. MY CAR HAS NEVER BEEN IN AN ACCIDENT AND I ALWAYS MAINTAIN THE OIL, TIRES, MAINTENANCE ON THIS CAR. NO ONE SHOULD EVER HAVE TO WORRY ABOUT GETTING IN THE CAR WITH THEIR CHILDREN AND FEELING UNSAFE BECAUSE OF MALFUNCTION AIR BAG SENSOR OR COMPUTER. THE ACURA DEALERSHIP SHOULD BE HELD RESPONSIBLE FOR THIS MALFUNCTIONING SYSTEM.
