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. A further 1 defect investigation is open and unresolved.

Red marks a system with a recall campaign against it. One complaint can name several systems, so these add up to more than 40.

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 21.

24 18 12 6
23 24 25 26

This is the year the complaint was filed, not the year the failure happened. The range runs from 2023 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 2024 Acura MDX, and it is a separate question from what owners report going wrong later.

Test SUV AWD SUV FWD
Overall Not rated
Frontal crash
Frontal, driver
Frontal, passenger
Side crash

Rollover Not rated
Chance of rollover — 15.1%

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.

The defect
Honda (American Honda Motor Co.) is recalling certain 2021-2025 Acura TLX, 2023-2025 Acura MDX, and 2023-2025 Honda Pilot vehicles. The brake pedal pivot pin was not secured properly, which can cause the pedal to shift out of position.

The risk
A brake pedal that shifts out of position can prevent the driver from applying the brakes as intended, increasing the risk of a crash or injury.
The remedy
Dealers will inspect and replace the brake pedal assembly as necessary, free of charge. Owner notification letters were mailed July 29, 2025. Owners may contact Honda's customer service at 1-888-234-2138. Honda's numbers for this recall are FLX and XLY.

An investigation means NHTSA has decided a pattern is worth examining. A preliminary evaluation is often closed with no action; an engineering analysis is the stage that usually precedes a recall.

the engine and its cooling

On June 3, 2022, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE22005 after the agency received VOQs and several field reports concerning the Auto Idle Stop (AIS) feature on 2016-2019MY Honda Pilot vehicles. The complaints allege that the engine fails to restart on its own from a complete stop at a traffic light or road intersection with the AIS function engaged. The subject vehicles are equipped with a 3.5L engine with a 9-speed automatic transmission. On January 6, 2023, Honda released service bulletins 23-008 and 23-009. These service bulletins address the failure to restart issue in the 2016-2019MY Honda Pilot vehicles, as well as the 2015-2020 Acura TLX, 2016-2020 Acura MDX, 2019-2022 Honda Passport, and 2020-2023 Honda Ridgeline vehicles. The repair outlined in the service bulletins is a two-stage countermeasure to remedy the issue. The first stage is a Programmed Fuel Injection (“PGM-FI”) software update. The second stage is only deployed if the software update fails to remedy the issue. The second stage, depending on the model and model year, consists of replacement of the starter assembly, starter relays, and a valve adjustment. Additionally, Honda extended the warranty coverage to 10 years with unlimited mileage for vehicles requiring the second stage component replacement. ODI continues to receive complaints of the AIS failure to restart, with many complainants alleging the campaign countermeasures had been completed.NHTSA has reviewed Honda's Information Request Letter responses involving warranty claims, lawsuits, and consumer complaints in addition to ODI's own data. This Engineering Analysis is being opened to further consider the potential safety defect, including gathering additional data regarding Honda’s service campaign efficacy. ODI is additionally expanding the scope to encompass all vehicles addressed in Honda’s service bulletins 23-008 and 23-009 as well as newer model year vehicles, which are substantially similar to the vehicles covered by the service campaign. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.

On more than several occasions the car has slammed on the breaks for no apparent reason. This has happened multiple times and thr dealer can’t fix the issue because the computer is showing no error.

UNKNOWN OR OTHER
I am reporting a potential safety defect involving the rear windshield glass on my Acura MDX. The rear windshield unexpectedly shattered while the vehicle was stationary, with no known impact or contact with an outside object. I was present when the glass shattered and immediately took multiple photographs and videos before the vehicle was moved. Based on what I observed, the glass appeared to break outward rather than from an outside object striking the vehicle. I later drove the vehicle from my home to the Acura dealership after being advised to do so. By the time the vehicle was inspected, portions of the shattered glass were understandably missing. The dealership later identified an

VISIBILITY/WIPER
Went to get into my 2024 Acura MDX parked car this morning temperature around 68 degrees and noticed the back window of my 2024 MDX had shattered out. There was a large section of glass missing and the glass looks as if it was pushed from the inside out. The vehicle had not been driven or started since the last evening. It seems as though this was a problem with prior Acura models in previous years. Went to the dealer and talked to the technician who said it is not covered under Acura warranty. This is definitely a safety issue as I could have been driving down the interstate when this happened putting my life and others in danger. I can only assume this is an issue Acura is aware of with

Every Acura on this site — 73 vehicles.

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.
