What 35 owners told NHTSA about the 2024 Acura MDX Sport Hybrid

When cruising or coming off a stop, my car is incapable of accelerating promptly if I am trying to get out of the way or even merge into oncoming traffic on a highway. There is a severe acceleration delay perhaps with the throttle body. I have seen online complaints but the dealership said there has to be an actual recall number to correct this. My car has been in several times to fix this. A computer reset did not work. My car is one year old.

Cruise control does not hold speed during transition from downhill coast to uphill acceleration. If set at 70mph on an interstate and car goes down a hill, coasting may slow to 68. When uphill is immediately encountered, speed drops to 64-65mph before finally accelerating to 70. Many trucks get very close and some honk because of the slowdown. Some road rage has been received. Also, throttle lags 0.5-1.0 seconds when transitioning from complete stop. Rear end collision has almost occurred when other drivers proceed to move forward and this car doesn’t move.

This car only has 2500 miles on it. When it was just driven a few weeks in January, 2024, the car would start jerking while driving down the highway going a consistent 55-60 miles per hour. We took it back to the dealer in St. Louis and they told us they were unable to duplicate. We drove it a few more weeks and in February the jerking was more pronounced and more often so we took it back. Again, they said they could find nothing wrong with it. It ran pretty good until mid March when I drove it to Florida for a 6 week break in my wife’s cancer treatment. The car jerked a lot and broke down completely 3 times. I was able to restart the first two times but the third time it took a while and I was stalled in heavy traffic on [XXX] north of Gainesville. Luckily, a trucker pulled up behind me and put on his flashers to keep me from being hit. After sitting there several minutes, it did restart and I drove to Ft. Myers where I took it to the Acura Dealer there, Scanlon Acura. They, too, ran diagnostics and said nothing showed up. I drove it to our condo and it died before I could turn into my driveway. I called Triple A to come tow it back. This time they gave me a loaner, said they checked it out and the manager drove it over night to his home. They said it had water in the gas tank and we had to pay for the draining as that is not covered. When I picked the car up the maintenance sheet also stated a leaky valve but said there was NO water in the gas tank. I had to request my money back and asked about the valve. Was told it was a mistake. On Saturday, [XXX], my wife was driving to an appointment down [XXX] and after about 35 min, the car started jerking badly so she pulled into a parking lot when it shifted into park on its own and died. She had to have it towed backed to Scanlon Acura. They they called yesterday and said the computer says nothing is wrong. This car is a death trap and we have to return home for her treatment in a few weeks. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
