2015 Acura TLX transmission problems

Filed Oct 5, 2026 · Transmission · CO

While driving my 2015 Acura TLX, warning lights illuminate and the vehicle unexpectedly shifts into neutral while the vehicle is moving. When this occurs, the vehicle loses the ability to accelerate normally, creating a serious safety concern in traffic. These symptoms appear consistent with the condition addressed by Acura recall KC2 (the federal safety agency Recall 16V‑640), involving the transmission wire harness/connection and transmission control system. The recall describes a condition in which the transmission can unexpectedly shift into neutral while driving. My VIN is not coming up under recall yet my vehicle has done this same thing multiple times over the past few months. I need my VIN added to recall list so this serious issue can be repaired under recall by Acura.

The fuel delivery system, specifically the fuel pump, has malfunctioned. This vehicle is subject to a fuel pump safety recall, which was reportedly repaired in 2022; however, the vehicle continues to experience the same failure symptoms and is available for inspection upon request. The vehicle has stalled multiple times at highway speeds, resulting in sudden loss of power while driving and creating an immediate risk of collision with surrounding traffic. My family was in the vehicle during these incidents, significantly increasing the risk of serious injury or death. The problem has been reproduced multiple times, including after the vehicle was taken to an authorized Acura dealership. During the most recent visit, diagnostic trouble codes were cleared, but the recalled fuel pump was not repaired or replaced. After being released by the dealership, the vehicle stalled again under similar driving conditions. The vehicle was inspected by the dealership, but no corrective repair was performed beyond clearing codes. The manufacturer has not yet properly remedied the recurring safety defect. Prior to stalling, the vehicle exhibited intermittent hesitation, loss of power, and engine shutdown. Warning indicators and fault codes were present at times and were cleared by the dealership without resolving the underlying issue. These symptoms have continued intermittently since the recall repair. This appears to be a failure to properly diagnose and correct a known safety defect, resulting in repeated dangerous highway stalls and placing occupants at serious risk.

Hi, I have had a couple instances where the engine revved up between gears. Both times, I remember it happening rather soon after starting off from a stop sign. I didn't pay it much mind, but noted it. Just today, I asked my wife ([XXX]) whether she had noticed anything with the car. I purposely didn't ask any leading questions. She said a few times it would jump instead of smoothly going to the next gear. In Seaside, OR, I started to pull out onto [XXX], planning to take a right and head south bound. There was a Southbound car approaching from the North, but I had plenty of time to pull out and get up to speed. Immediately after starting out, the car popped into neutral and the RPMs raced. I already had some momentum and was on the highway, so I couldn't brake, and because it went into neutral, I hadn't finalized my turn so I was still pointing SE. As the car quickly approached, all I could do was use what little momentum I had and continue into the Northbound lane so the oncoming car could pass. Because of the slight slope to the Northbound shoulder, I was able to slowly come to a stop. I put the car in Park, turned it off, then back on, and everything came back to normal. I cannot begin to express how scared I was. I have lost brakes before in a car, but I know to use the emergency brake. I was completely dumbfounded as to how to react. Had there been oncoming traffic, it would have been an awful accident. Why is there no recall on this? I researched on Google and found a recall on 2015 Acura TLX 6-cylinder transmission due to a bad wiring harness on their 9-Speed transmission. I know mine is an 8-speed, but would it not use the same wiring harness with slight modifications? INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving on the freeway/highway my vehicle went into limp mode and shifted into neutral. My vehicle would not allow me to shift gears and the car would not let me accelerate anymore. I had to think quickly and move out from upcoming traffic. With little speed I had on my vehicle I could only shut down the car and wait for a tow truck. This happened to me twice in 2020 and the mechanics could not find any issue or replicate what had happened. They said this was a software issue. I was still scared to drive my car thinking this would happen again. Then 2 years after ( 2024) again this happened and it was when I was on the freeway. Luckily I was on the left side and was able to stop on the shoulder but stressing out and still traumatized from what occurred 2 years ago. I took it to the dealer and same thing they could not replicate the issue and did re programmed the software. I believe this car is not safe to drive at all knowing this can happen again and again at random times. The attached document is what the dealer gave me stating this remedy was done to the vehicle. This need to be investigated.
