Deaths

A complaint is an unverified account by the person who filed it, not a finding of fault. One complaint is one ODI number, which is how NHTSA counts them.

A recall is the manufacturer conceding a defect, and the repair is free. Whether one covers your particular car is a question only its VIN can answer, because a campaign covers a production range rather than a model year.

Red marks a system with a recall campaign against it. One complaint can name several systems, so these add up to more than 113.

When the complaints arrived

By the year NHTSA received them

By the year NHTSA received them, which is not the year the failures happened. They peaked in 2025 at 27.

32 24 16 8
20 21 22 23 24 25 26

This is the year the complaint was filed, not the year the failure happened. The range runs from 2020 to 2026, the last of them a part year, which is why its column is drawn faint.

Crash test ratings

NHTSA New Car Assessment Program

NHTSA crashes a car into a barrier and a pole and measures what happens to the dummies inside. This is what it awarded the 2021 Acura RDX, and it is a separate question from what owners report going wrong later.

Test SUV AWD SUV FWD
Overall
Frontal crash
Frontal, driver

Side crash

A rating belongs to a tested body style and drivetrain, not to the model as a whole, which is why more than one is listed. A dash means NHTSA did not rate that test for this vehicle.

STRUCTURE:BODY

1 injured

The panoramic sunroof exploded on our Acura RDX model 2021. Me, my wife and our 3 month old son were returning from dinner, we took the ramp and about to merge on a highway then we heard a loud and sudden explosive noise which scared all of us. Thank God we had the sunroof blind partially closed over the real infant seat, so the glass shatters left some minor cuts on my left forearm and back (glass pieces got between my back and driving seat). Also, the glass pieces did cut the sunroof blind/rolling cloth screen. We are glad that we made home safe and not sure what is the process of getting the issue fixed by the manufacturer and thorough cleaning up of the glass remains/dust. Please advise.

VEHICLE SPEED CONTROL

crash · towed

Drove into parking lot and as I was pulling into the parking spot next to the building, the vehicle started to surge forward as if I had my foot on the gas instead of the brake. The sudden surge caused the vehicle to plow into a brick building causing about $10K damage to the vehicle and $5K to the building. This was not the first time this sudden surging occurred. It happened at least 3 times previously, and one time since. Fortunately, the other occurrences did not lead to any damages, but just some anxious moments. I took the vehicle to the dealership to get checked out after the last occurrence, but they said they couldn't duplicate it. I thought it might be some sort of "unknown"

SERVICE BRAKES

crash · towed

Two low-speed sudden unintended acceleration events while parking a 2021 Acura RDX. Incident 1 (July 2026): While parking at low speed, the car unexpectedly surged forward. Flew up the curb and hit a restaurant window, causing massive undercarriage damage. Active braking did not help and seemed to make acceleration worse. It only stopped when it wanted to. Incident 2 (August 2026): Two weeks after getting the car back from repairs, under identical low-speed parking conditions, a second sudden acceleration event occurred. Slamming on the brakes did nothing. It stopped after scraping a car wash vacuum pole, destroying the entire passenger side. Prior to these, the car exhibited erratic safety

SERVICE BRAKES

crash

While sitting in a long row of stopped vehicles at a traffic light for an extended amount of time due to an accident I had the Automatic Brake Hold feature activated { I did not have to have my foot on the brake while sitting still) as well as the Auto Idle Stop OFF button meaning {the engine shuts down when you come to a stop.} Apparently, the Brake Hold feature timed out with no warning whatsoever and because the vehicle moved forward the Auto Start Stop feature activated at the same time and the vehicle lurched forward rear ending a new expensive SUV in front of me. The impact was hard due to the quick lurch of my vehicle. I have damage to the front of my vehicle and all of the

ENGINE
Head Gasket blown known problem with Honda and Acura 2.0T I didn’t know of this issue until it occurred to Loi Me in 2025 My Acura dealership told me it’s a huge problem with the Acura RDXand it should be a warranty extension similar to the warranty extension for other Honda products done in August 27, 2026 I was lucky and my head gasket didn’t blow while I was driving I’m also concerned that it’s gonna happen again I’m not sure if the problem was resolved with the new head gasket or it’s a stomach problem with the motor that has not been addressed yet

FUEL/PROPULSION SYSTEM
Fuel Pump is having to be replaced. I have had issues accelerating and my car also stalled once on the freeway. It put me in a dangerous situation and I almost got in an accident because my speed quickly decreased. The same part was recalled on the previous year’s model.

POWER TRAIN
I own an Acura RDX that experienced a sudden failure of the transfer case. Prior to the failure, there was little or no warning that a major drivetrain component was about to fail. When the transfer case failed, the vehicle lost its normal all-wheel-drive operation and required expensive repairs. I believe this is a safety defect because the transfer case is a critical drivetrain component. A sudden failure can reduce traction and vehicle control, especially when driving at highway speeds or on wet, snowy, or icy roads. Drivers may not expect the loss of power to the rear wheels, which could increase the risk of skidding, loss of stability, or being unable to safely accelerate into traffic

If this is your car and a dealer keeps failing to fix it, your state's lemon law may require the manufacturer to replace it or buy it back. How many repair attempts it takes, and how long you have to file, is set by the state you bought in and by nothing on this page.

Where these numbers come from

A complaint is one owner's account and has not been verified by NHTSA or by us. A vehicle with more complaints is not necessarily worse: models that sold in larger numbers collect more of them. How this is counted.
