“During the summer of 2025, the auto idle engine railed to restart while at a stop light. We had to shut off and restart the car. We took it to the car dealer and they did some sort of software update. It happened again in January 2026 while at a stop light off a highway exit ramp. We took it to a different dealer because we were living in a different city at the time. In their computer system, they could see the repair that had been done. They did some sort of other update and submitted it as a warranty repair for Acura (which the other dealer had not done). They noted there was one other repa…”

Fuel/Propulsion System 15
“The car had several warnings lights come on and immediately stalled out and stoped right in the middle of the road. The engine would turn over but would sputter like it was out of gas and would die after a few seconds. It stoped in the middle of a busy state highway in a curve. Luckily no one got hurt. I towed it to an auto service center. The 2020 Acura MDX suffered an in-tank fuel pump failure causing a low fuel pressure code (P0087). This model year is under a massive 2.6-million vehicle safety recall, but my specific VIN was omitted. It likely should be included before someone gets hurt.”

The loss of propulsion prevented acceleration and forced us to coast across traffic lanes to reach the shoulder, creating a significant safety hazard. The engine would not restart. The vehicle was inspected on 3/17/2026 by Lyle Pearson Acura (Boise, ID). The dealership diagnosed catastrophic internal engine failure with the following findings: spun rod bearing in cylinder #6, excessive metal debris in the oil pan,…”

Service Brakes 15 2 crash
“While sitting stopped at a red light, the brake pedal suddenly became soft and the vehicle began moving. As I rushed to depress the pedal further (all the way to the floorboard - which did not stop the car) the car rolled forward and collided with the car in front of us causing damage to both vehicles. If the other car had not been in front of us we would have rolled directly into heavy active cross traffic which would have caused significant harm to all inside. My daughter, niece, and 8 month old grand-niece were with me in the car.”

“I was pulling up to our house to park in the open garage as I typically do and was in the driveway with my foot lifted off the gas pedal to allow the car to coast forward slowly. The car hesitated for a moment before it lunged/accelerated on its own with such force I had to slam on my brakes to avoid the car hitting the wall of our house. I did not have cruise control on. Took the car to Acura dealership for a multi-point inspection and they found nothing out of order that would’ve caused that to occur.”

Structure 1
How we read this (methodology)
How to read this: raw complaint totals are not a clean reliability score — a model year with more cars sold, or simply more years on the road, accumulates more complaints regardless of how good it is. So this page leans on two signals that are not distorted by sales volume: the share of complaints falling on each vehicle system (the breakdown above) and NHTSA's own crash / fire / injury / death flags. When we compare model years of the same model, we normalise by years on the road (complaints ÷ vehicle age) rather than comparing raw totals. Age-normalised, the 2020 Acura MDX draws about 30.0 complaints per year on the road, ranking 2 of 14 among the Acura MDX model years we have ingested (1 = most complaints per year on road).
Before you buy this Acura MDX
Don't buy on the strength of a problems page alone. Check the exact VIN of the car you're looking at. The open recalls are free, and the full $19 safety report pulls every complaint, safety rating and a downloadable PDF for that one vehicle.
