What 36 owners told NHTSA about the 2023 Acura MDX Sport Hybrid

The contact owns a 2023 Acura MDX. The contact stated that while driving at various speeds over a bumpy road surface or a pothole, there was an abnormal metallic sound coming from underneath the passenger’s side of the vehicle. No warning light was illuminated. The vehicle was taken to the dealer, where a technician informed the contact that the sound was common after 50,000 miles. The contact was later informed that the cause of the failure was undetermined. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure, but the assigned case manager failed to help. The failure mileage was approximately 50,000.

A little over one year after purchase, I began receiving dashboard warnings related to the air suspension and braking systems. I scheduled service with the selling dealer (located over two hours from my home). By the time of my appointment, the rear of the vehicle was visibly unstable and bouncing during operation. Upon arrival at the dealership, while the technician was driving the vehicle into the service bay, the rear air suspension bag exploded. Once the vehicle was raised on the lift, the opposite rear suspension bag also exploded. I was informed by dealership personnel that had this occurred while I was driving – regardless of speed – it could likely have resulted in a crash. The stated cause of failure was severely corroded rear stroke sensors. Including that incident, I have had a total of 5 corroded stroke sensors replaced within an approximately one-year time frame. This appears to be a recurring and systemic defect rather than isolated component failure. The repeated corrosion of critical suspension components in a nearly new vehicle raises serious concerns about moisture intrusion, improper sealing, or design defect affecting safety-critical systems. This issue creates a significant risk of sudden suspension failure, loss of vehicle control, and potential crash. I am concerned that other owners may experience similar dangerous failures without warning.The vehicle has been serviced only at an authorized Acura dealership, and all repairs are documented. Exact dates of each repair: 4/10/25 – Both rear stroke sensors (mileage: 13,632), 9/24/25 – Left rear, 2/6/26 – Right front, 3/20/26 – Left rear, Current mileage: 25,160

I bought the car in March 2023 and took the car for maintenance of 5k at Acura dealership at north Orlando and after that the car came never the same. The car is making so much noise skewing and clicking noise every time you turn the streering wheel. The dealership said the noise is from nuts and bolt and they did change it and noise became more loud 2nd time they said it is the front break and they did change it and the noise still the same and more of clicking noise with every tire turns . I do have a video but I could not upload it. Then for 3rd time and car been sitting at dealership for a month now they said this noise is normal and happens with all Acura MDX models. The Loaner I have is an MDX that never makes any noise . The car was running perfectly fine before the maintenance. Now noise and steering wheel very loose and does not feel the same as before and you can hear 2 different noises in car one with breaks on and one with car or park and just Turing the steering wheels. So unbelievable that the damaged my car and I barely have mileage on it and changing all of those parts and when they came to a point that they can’t solve the issue they are saying it is a normal noise. Is it in car manual ? Why you changed all those parts to start with if that car and noise were normal? Too many questions and hidden parts for the dealership and Acura manufacture they just know half of the story and only listen to dealerships. I don’t feel safe driving the car with all of those issues and having two kids with me all the time.
