Consumer Description
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 NHTSA 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.
