“I have experienced sudden acceleration problem numerous times( 5 to six times. The latest one was march 1,2021. The vehicle would accelerate (RPM rapidly ) suddenly when driving at low speeds(around 10 to 15mph to a quick almost 30mph without pressing the gas pedal) that always require me to break immediately to avoid any accidents. I had the vehicle checked thoroughly by a company sent expert last year(sometime nov ,2020) and they can't replicate the problem. Acura relations can't help me anymore . It made me google unintended acceleration MDX. The problem is for real. …”

“Periodically when accelerating the car (2020 Acura MDX) looses power. The car does not stall it just looses power. There have been times when we have had to pull over to avoid causing an accident. When it does occur there are no warning or signal displayed on the dash boards pre or post the incident. We have reported the issue to Acura but there has be no resolution to the issue.”

NHTSA complaint #11515930, filed 2023-04

“upon turning right, the car lost power, degraded acceleration as if someone is holding and pulling the car to move forward. The traffic behind me expected me to cathup with the speed on the road but due to loss of power and engine hesitation i got honked and was luck to avoid a crash from behind on a busy road. Acura dealership in Dallas dont have parts since a very long time. They have pleant of new cars to sell but not repair.”

“My car has been going into neutral when in the autostop. The only way to get out of it is to turn it off and back on. It's incredibly dangerous. I almost got into a horrible accident. It happens suddenly and without warning.”

NHTSA complaint #11663592, filed 2025-05

“When using the a/c while the Auto Idle Stop is engaged, the engine will shut off and not restart. This issue does not happen immediately, at the first cycle of being activated, it's after 3 or more cycles of the AIS being in use, like driving in stop and go traffic for instance. The issue reminds me of a low/dying battery when it happens. Now when I turn off the A/C, the car starts right up like normal. Also if I don't use the A/C, the AIS cycles like normal, like in traffic, l'll have no problems with its performance.”
