At only 44,318 miles, my 2019 Acura MDX began showing clear transmission problems in the lower gears — including delayed acceleration, gear slipping, and jerky movement when starting or turning at low speed. These symptoms posed an immediate safety risk, especially when merging into traffic or making turns across oncoming vehicles. I first brought the car to Oakland Acura, which incorrectly diagnosed it as a transfer case issue. Their misdiagnosis delayed the repair process and added unnecessary cost and time. I then had the vehicle evaluated at Acura Concord, where it was correctly diagnosed as transmission failure in the lower gears. An independent, certified mechanic also confirmed the same diagnosis. Despite multiple confirmations of premature transmission failure — and a full maintenance history — American Honda offered only a $900 discount on a $9,600 repair, citing the vehicle being just outside the time warranty (but with low mileage well under 50K). I believe this is a manufacturer defect, not a wear-and-tear issue. Safety Concern: This transmission failure is not just inconvenient — it is dangerous. The vehicle hesitates when accelerating from stops or low speeds, which can lead to accidents at intersections, highway merges, or left turns. The misdiagnosis further delayed identifying and addressing this issue. I am filing this complaint to urge the federal safety agency to investigate whether this is part of a broader pattern with Acura MDX transmissions, and to help prevent similar risks for other drivers and families.

In front of the red light on the way to work in a morning, I stopped my MDX, then when the red light changed to green, I pressed gas pedal to cross over the street, but unfortunately, my car was pulled backward, and meanwhile, I heard a loud sound of Bang from my mdx. I suspect that the loud sound must be from the gears conflicting in the transmission when automatic transmission shifts. Moreover, the car jerks at around 45 mph speed sometimes. Acura must recall fixing this issue.

I was yielding to make a left hand turn , in the middle of the intersection, and my car turned off and wouldn’t turn back on. In addition the car occasionally jerks as I’m driving almost like if it changes gear. Sometimes I can’t get the car in park position I have to press the button multiple times. The recall going on right now can cause a fire crash or injury and they cannot replace the parts until April 2024 and I don’t feel safe driving my car.

I have had problems with the car stalling or shifting to neutral from drive after the auto stop feature is engaged. This typically happens when the engine tries to restart after having shutoff at the stop. It is difficult to replicate the problem and the dealer can't seem to replicated the problem but it has happened to me many times, particularly in hot weather or after long drives. Typically it happens after a long drive or a lot of around town driving (maybe when the engine is hot?). The dealer does not believe it is related to the fuel pump replacement but that is when it seemed to have started happening but this is entirely speculation. Very frustrating as I have been to the dealer 3 times with the problem and they cannot "replicate" it. They supposedly also replaced the battery and updated the software in the car but that has not solved it. I am growing concerned because it is very dangerous, particularly when stopped at a busy intersection. The last stall happened and it took a minute or so to get the car running again at a busy and large intersection. I am also worried about the happening when on an incline. It doesn't happen all of the time, sometimes there is just a hesitation but the car starts and lurches forward. I have a 2019 with about 35K miles on it and have used primarily for long distance trips and not much around town driving. I have attached the dealer work orders for the three visits but stopped bringing the car in because it has been a waste of time as they are unable to find the issue. Also, I have reported the issue twice to American Honda and they have sent me back to the dealer with no results. This is a dangerous situation and I noticed that there is a related recall for the Acura TLX model with the same engine. This problem is ongoing and has happened to me twice in the past 2 days if I forget to disable the auto shutoff feature. Thanks.
