What owners say about the power train

Verbatim from NHTSA complaints, newest first
“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 (NHTSA 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 contact owns a 2015 Acura TLX. The contact stated that while driving at undisclosed speeds, the vehicle hesitated while accelerating. The message to stop driving and have the vehicle serviced immediately was displayed. The vehicle was towed to the dealer, who diagnosed that the Automatic Transmission Fluid (ATF) warmer had failed. The dealer diagnosed the vehicle with other undisclosed failures due to the ATF warmer failure. The vehicle was not repaired. The manufacturer was informed of the failures and opened a case. The failure mileage was approximately 77,000.”

“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…”

“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…”
