2023 ACURA MDX

ELECTRICAL SYSTEM

LOSS OF POWER STEERING AND BRAKING ASSIST REDUCED. My spouse was driving our 2023 MDX approximately 45mph when she ran over a recessed manhole cover which created a bump. The MDX lossed power steering and brake performance reduced. The vehicle was very difficult to turn at that point. The car began to cycle through errors that would not clear until the car's engine could be stopped and restarted: HILL START ASSIST PROBLEM, TRAILER STABILITY ASSIST PROBLEM, ADAPTIVE CRUISE CONTROL PROBLEM, LANE KEEPING ASSIST PROBLEM, COLLISION MITIGATION BRAKING SYSTEM PROBLEM, ROAD DEPARTURE MITIGATION SYSTEM PROBLEM, LOW SPEED BRAKING SYSTEM PROBLEM, ELECTRICAL POWER STEERING SYSTEM PROBLEM STEERING ASSIST IS NOT AVAILABLE DO NOT DRIVE, AWD SYSTEM PROBLEM FRONT WHEELS MAY ONLY BE POWERED, BRAKE SYSTEM PROBLEM BRAKE PERFORMANCE MAY BE REDUCED. All these errors said SEE YOUR DEALER. We took the vehicle in to our local Acura dealer's service department 2 times over the course of 3 days. Both times diagnostics were ran and the car was deemed without problem. The MDX's alignment was ok as well, so the impact of the road hazard was NOT severe.

POWER TRAIN

Transfer case became defective and fluids started mixing in with it and in the result of all of that I needed a new transmission as well

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

My 2023 Acura (VIN# [XXX] ) has experienced two separate incidents of sudden, total power loss while driving. In both cases, all dashboard warning lights came on, including the brake light, and the vehicle reduced speed to 20 mph and would not accelerate. The first incident occurred while I was driving on a 55 mph expressway, creating a major safety hazard. I had to maneuver to safety in high-speed traffic. The second incident occurred under similar conditions. The dealer has been unable to resolve the issue. I am filing this report to document the safety risk for investigation.

Multiple system warnings lights on dash appear indicating multiple systems issues including possible loss of power. See video First occurrence- August 2024 - Dealer said it was due to software that needed to be updated. The repair was completed. Second occurrence - May 2025 - dealer has car for over a week and is unable to find the problem. No codes were stored so they say they can repair it. Honda says it’s the dealers problem I have the last occurrence on cell video but I’m unable how to upload as it’s not jpeg

STRUCTURE:BODY

Bought the car brand new, at only 10k miles, found out that the fender liner is falling off from the frame. During the rain, it gets heavier and pulls further down. Eventually fabric will fall off and will hit the tire while driving and possibly cause an accident. Tried to get it fixed by Acura dealership but they're saying it cannot be fixed because it's manufacturing defect.

SEATS

I have a 2023 Acura mdx type s advanced with 16k miles on it and the front driver seat at the bolster is starting to separate and many other owners is having this same issue on their type s models I attached multiple pictures of my seat which is the white seat and other owners seats

POWER TRAIN

I hear a high-pitched whistle when I the speed reaches around 57-63MPH. I've taken it to the dealer a couple of times, and they said it's normal. I am really disappointed that Acura didn't fix it...

I have had a on going issue with using the touch pad which controls the GPS navigation , mobile phone and FM & XM radio operation. Trying to use any of these while driving or even when the vehicle stopped on the side of the road is very dangerous . The display screen is not a touch screen like most vehicles. Only the driver can select options using the touch pad which is located between the passenger and drivers seat console. It's a very dangerous distraction as you have to spell out letters using your finger to find a location while using the navigation system . Also the pad is so sensitive it makes you repeat the letter over and over in order to find the location you are trying to type in. Also something as simple as changing the FM or XM radio station requires you to use the touch pad . While trying to use the touch pad it forces you to take your eyes off the road to operate the system. The same issue with the mobile phone which is controlled by the touch pad when connected. I understand the newer models have went back to a touch screen operation. I've complained to Accra customer service as has others , but they haven't taken any actions to correct the problem. Most owners of these vehicles are families with children and senior citizens. Hopefully the NHTSA will investigate this very dangerous situation and require ACCURA to replace the current system with a touch screen operation or the option to have both .
