I am filing a complaint regarding my 2022 Acura MDX Type S with approximately 70,700 miles. The vehicle developed a suspension system warning, and upon inspection by an Acura dealership, I was informed that the suspension stroke sensor and floor wiring harness are corroded and require replacement. I was quoted approximately $12,000 for the repair. This failure is extremely concerning because the vehicle is only a few years old and this type of corrosion affecting a major wiring harness should not occur under normal operating conditions. The affected components are part of the suspension system, which directly impacts vehicle handling and safety. Due to the failure, the suspension system may not function properly, potentially affecting ride height, stability, and overall control of the vehicle. This raises safety concerns, especially at highway speeds or during emergency maneuvers. There was no prior warning of water intrusion or external damage that would reasonably explain this level of corrosion. This appears to be a premature failure of a critical electrical component. Acura has only offered minimal goodwill assistance, leaving the majority of this extremely costly repair as the responsibility of the owner. I am concerned that this may be a broader issue affecting other vehicles and that it could pose a safety risk if not addressed. I am requesting that this issue be investigated. Thank you.

MDX Type S with 63k miles. After performing diagnostic check there were several fault codes related to the vehicle's suspension system. Upon inspection, they identified issues with the ride height (stroke) sensors and wiring. The right rear, left rear, and right front sensors are affected. The right rear sensor has a broken pin, and part of that pin is stuck in the wiring connector. The left rear sensor also has a pin that is corroded. Additionally, the main wiring harness along the floor is corroded. This is due to poor location of wire harness in the Type S, and corrosion was due to salt exposure from icy roads. Dealership confirmed this was a known issue and had about a dozen of these replacements in the last few months.

The car threw several warning lights on the dash. The main indicator was that there was a problem with the air suspension: "Adaptative air suspension problem. Please see your dealer." The left airbag on the suspension then popped, rendering the car undriveable as the compressor would constantly blow air to try to inflate the airbag. The car was repaired at an independent facility at the cost of $2900.00 to replace the suspension airbag and the height sensor, as well as recalibrating ADAS. The car had 66k miles at the time of the incident.

There were two major failures in my vehicle within a couple of weeks. The first was a lower ball joint failure. The passenger side lower control arm was replaced. The second major failure was the transfer case seal on the transmission failed and the transmission is being replaced. The vehicle has been serviced since its new purchase at Acura dealerships.

2022 MDX Type S. So far I have replaced one tire and two rims. Air suspension does not absorb any road hazard. Pot holes or expansion cracks the front end dives into them letting the tires and rims absorb the impact. Thank goodness no high speed loss of tire pressure

Suspension clicking noise when turning wheel to from one end to another. I found that the outer tie rod end ball joint wasn’t torque down. I double checked the lower ball joint and found it wasn’t torque down as well. The clicking went away after torquing down the outer tie rod joint.

We purchased the vehicle on April 2nd. The front left strut airbag burst while we were driving at 23 miles an hour. Thankfully were weren't going fast when the failure occurred. I would imagine that at highway speeds this could greatly impact your driving ability as the front left of the car dropped down about 6 inches. The dealer currently has the part on backorder but has yet to attempt a repair. Our vehicle has been out of commission for 26 days. We got about 15 warning lights and parked in our driveway as we happened to be near our home when the strut broke. We had the vehicle towed to the nearest Acura dealership.

The car is making extreme noise from the rotors and it’s screeching. I took the car to paragon Acura multiple times and they stated it’s normal. A brake sign pops up and the car seems extremely unsafe. I have videos to to show everything
