Power train
161 reports5 crashes2 related recalls
“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.”

“I am reporting a catastrophic safety defect and a failure of a federal recall remedy on my 2015 Acura TLX. My vehicle was previously identified as part of the connecting rod bearing recall (NHTSA Campaign Number: 23V751000). The dealership performed the official recall inspection/remedy in February 2026. However, in September 2026, the engine suddenly developed a loud, metallic knocking sound coming directly from the motor. A metallic knock is the primary warning sign of imminent rod bearing failure, which poses a severe safety risk of sudden engine seizure and stalling while driving at highway speeds. I contacted Acura Customer Service to report that the recall remedy failed and that the vehicle is unsafe to operate. Acura corporate has completely denied my claim and refused to take corrective action, despite this being a direct, unmitigated failure of the recalled component.

“The emergency brake system continues to come on and read all the type of stuff on the screen, as well as the LKAS keeps coming on the screen showing problems and when it does, the transmission or engines stalls a little and slows up and speed down on its on”
Service brakes
24 reports7 crashes
“The car is constantly throwing codes for faulty emissions system problem and parking brake problem but the car runs fine. The dealership will not do anything unless I pay them a fee to diagnose it and then they suggest replacing the catalytic converter even though it’s very likely a faulty fuel hose or faulty sensor. This needs to be recalled and fixed immediately”
