I would like to report a serious safety issue with the 2021 Acura TLX Type s. Recently in April 2024, while driving, I heard a loud pop from the vehicle, and it turned out that the transfer case had burst into the transmission. This failure has rendered the rear-wheel drive non-functional, resulting in severe oversteer. This oversteer is especially dangerous because the vehicle is now operating as front-wheel drive, which creates an unpredictable and hazardous driving experience. This issue could lead to a catastrophic transmission failure, particularly at highway speeds, posing a severe safety risk to me and other drivers. I have contacted the dealer about the problem, but they have refused to take any corrective action. I-??ve also found that multiple other owners have reported similar issues with this model, highlighting a potential widespread problem with the transfer case and transmission interface. Given the safety risks associated with this failure, I urge NHTSA to investigate this defect and take appropriate action to ensure public safety.

I am reporting a critical safety issue with my 2021 Acura TLX (VIN: [XXX] ), specifically related to the transmission and transfer case. The problem is centered around the transmission-??s spline splitting into the transfer case, which causes severe jerking while driving. The car moves forward erratically, jumping up and down, and on multiple occasions, the vehicle has shut off while driving at highway speeds. This is extremely dangerous and poses a significant risk to my life and others on the road. This issue is widely reported by other Acura owners online, and it appears to be a common defect with the transmission, specifically the remanufactured transmission part number 06200-6T2-A02RM. The cost of repairing this issue exceeds $5,000, and since the vehicle is no longer under warranty, I am deeply concerned about having to replace both the transmission and transfer case, only for the same problem to recur. The vehicle is still drivable, but the issue is worsening, and I fear for my safety. I urge the NHTSA to investigate this matter and press Honda/Acura to address this defect immediately, as it is a severe safety hazard.

My vehicle was stolen due to a jammer that copied my car keys information. I have it on video. It was addressed to acura and honda about the vulnerability for past 3 years and they ignored it. I now am a victim of a stolen vehicle because of this vulnerability that was not acknowledged

I was driving down the freeway, in a new 2021 Acura TLX with 2000 miles on it. It was raining when I went to switch lanes and floor it to pass another car and the check engine light came on and the power dies and speed dramatically slows down and I-??m unable to accelerate. The check engine light is flashing and the car will not reach 40mph. Again I-??m on the freeway. This was a very dangerous situation. There were no warnings leading up to this catastrophic fuel/engine issue. I took the car to the Acura dealer who said there had been reports of issues related to water getting into the car-??s intercooler for the turbo causing the car to misfire and then going into -??safe mode-?? with a flashing check engine light. They installed Acura SB 20-053 PGM-FI update. I-??m picking the car up on 2/6/22 and hoping the issue is resolved. Again this was a serious fuel engine issue that if I-??d been passing a car on a two lane road into oncoming traffic could have been deadly
