Please add me to the compliant pool. My transfer case/transmission went out - 2022, 80,000 miles. March 6, 2026 NHTSA campaign number: dp26001 open investigation all wheel drive allegation NHTSA action number: dp26001 components: power train opened from: March 6, 2026 – present summary the office of defects investigation (odi) received a petition dated January 9, 2026, requesting an investigation into the loss of the optional all-wheel drive capability in model year (my) 2021-2023 Acura tlx and my 2022-2023 Acura Mdx vehicles. The petition contends that the interfacing splines between the transmission and the rear wheel drive power take off unit are failing. Failure of these splines prevents the transfer of drive power to the rear axle, making the vehicle front wheel drive only. The petition further alleges that this failure results in a reduction of vehicle directional control. The petitioner cites 48 complaints received by odi alleging the same failure. Odi will evaluate these complaints to determine if they are related to the failure cited in the petition and will conduct a technical review under 49 cfr part 552. This defect petition is being opened to evaluate whether to grant or deny the petition. The petition can be viewed at NHTSA. Gov under NHTSA number 11712885.
The engine suddenly shut off when the vehicle was waiting for traffic light and at full stop. The vehicle would not restart after multiple attempts and had to be towed to dealership. Mechanic at the dealership said the "idle stop" feature can drain the battery quickly and had to replace a new battery. We consider this a reportable safety hazard and a potential design defect because 1. The "idle stop" feature is turned on by default, though it can be manually turned off. 2. The incident occurred in a very abrupt and unpredictable fashion. The vehicle was started normally about 30-40 minutes before the incidents and has been driven normally in a typical city traffic condition till the incidents occurred. During this period, the computer system did not give off any warning related to a total battery failure.
I was driving my car on the interstate and momentarily stopped due to traffic congestion. My engine idle stop feature was on and engaged as expected for the short stop, but the vehicle then stalled when I attempted to drive. There seemed to be an electrical issue with various lights coming on the dash to indicate a problem. I could not get the car to restart and was stuck in the left lane with cars then going around my stalled vehicle. I called 911 for help after I could not restart the car after 3 attempts. After approximately 5 minutes, I pressed the ignition button again, and this time my car was able to restart and drive normally so that I could exit the highway.
Acura headquarters USA 1919 torrence boulevard torrence, California 90501 mr. [xxx] [xxx] [xxx] email: [xxx] dear sir or madam, I am writing your company to the attention of whomever oversees the product development and design of the 2022 Acura Mdx and to warn them that certain system features and design flaws of this make and model vehicle will undoubtedly lead to the death of someone in the near future as was nearly the case with myself and spouse very recently. On Sunday [xxx], my spouse and I attended church services that morning. Fortunately, after services our Acura Mdx did start as usual, and we began our journey home. Upom arriving home, we backed our car into our garage and during that process thankfully I had the wits to unlock the passenger and driver side door mechanisms. Once we enteredthe garage and at thta point, our car went absolutely dead. Our car stayed dead for the next 5 1/2 hours. Had I not unlocked those doors, we would have been trapped inside for that duration of time, only to be found dead fron suffocation and asphysxiation from being in a car with all the windows rolled up, no power to the vehicle and no way to get out, while beingdeprived of oxygen. At that point, your manufactured vehicle became a death trap for us. We're the fortunate ones who lived through the experience and to be able to tell the story. Others may not be so lucky to tell theirs and there will be others. We wanted the manufacturer to understand the full implications of our letter and to stress in the strongest terms possible that this is a very serious matter that will eventually cost lives, as it nearly cost us ours. The vehicle in question is VIN# [xxx] and was last serviced at vandergriff Acura in arlington, texas on 6/13/2025 information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
I've recently been in touch with an Acura dealership about my vehicle's wireless charger not working. So shortly after purchase I made my complaint that the wireless charger pad is not charging my phone. They've replaced the pad but still not charging my samsung ultra 22+ unless the car is parked and sitting still. They've asked me to allow time for researching the issue and taken all the make model details from my phone. Well sadly a few other things recently became noticeable to me as well and I will be following up with the dealership to address them as well as I'm not satisfied with my truck and the many issues I'm experiencing. 1) jerked when coming to a stop to reverse into my driveway 2) a loud thud noise could be heard inside my truck although I had the radio on when switching from park to drive or drive to park. 3) car stopped kind of midway when reversing jerking me in the process leaving me wondering why or what was going on. 4) engine would rev to 7000rpm even though I was going less than 45 mins per hour. . . . Just baffling honestly.
The contact owns a 2022 Acura Mdx. The contact stated that while sitting at red light, a white colored smoke began to emit from front passenger tire wheel well. The contact was then alerted by a fellow motorist that the vehicle had caught fire. The contact exited the vehicle and called for assistance. The fire department arrived at the scene extinguished the fire. A police nor a fire report was filed and no injuries were reported. The vehicle was towed from the scene to the dealer where it remained in their possession. The manufacturer had yet to be notified of the failure. The vehicle had yet to be either repaired or destroyed. The failure mileage was 26,000.
The vehicle makes noise while shifting from park to reverse to drive. Transmission fluid and oil fluid leaking while I had driven only 450 miles. Had reported the issue to the service department. They informed that since the engine is new it will take a while for the transmission gear to quiet it down. They can't find any leakage for the first two times when I brought the vehicle for them to inspect. Their service manager was able to identify the issue and assigned the technician to trace it down. My car is currently in their shop for the third time since I just purchased it on August 19th, 2021.
