2015 ACURA TLX Complaints

First item: vehicle keeps shutting off during idle while parked or while brake is depressed. It has happened multiple times. I've done some research and see there are several sites indicating issues with the fuel pump and vehicle stalling. Acura says there are no current recalls. I'm not the only person this is happening to. Second issue: vehicle has gone into neutral on its own while driving. At first I thought maybe I hit the neutral button by mistake and didn't think of anything but then the most recent was coming out if a gas station and pulled up to a stop sign and it went into neutral. I just bought this car on June 1st.

While driving, the vehicle shift into neutral unexpectedly, causing the transmission indicator to come on and OTC. Was going downhill when it happened but luckily I got off the road and went into a residential neighborhood to park. It was left on Neutral and could not shift to any gears. I put the emergency brake so the car wouldn't move down. I later found out after the car was towed that I was able to shift gears due to turning off the vehicle. P0657 was the code provided when it was scanned by an OBD2. VIN# 19UUB2F33FA014519

Engine shut down at stop (gas saving feature) when I try to go again give it gas car stalls.

This issue is with the start-stop system. The car fails to restart after it the car stops and the engine shuts off. The car has been serviced twice for this issue. The battery and a cable were replaced at my expense. This resolved the issue for a few months, but it returned again in February of 2022. The battery was replaced under warrantee at that time. This issue has now returned again July, 2022. In at least two of the instances I felt I was extremely at risk as the car was stalled in busy intersections forcing traffic to make emergency stops be hind me or take evasive actions to avoid hitting my car. The normal starting procedure to start the car did not seem to work. There was nothing to indicated to me that there was an issue.

Consistent issue with the auto idle start stop system. This has been a continuous problem during the life of the car. It has happened while stopped at traffic lights, in traffic and while in the drive thru line at fast food restaurants. As a deterrent, I try to remember to disable the auto idle start stop every time I start my car.

Car has feature that kills engine when at full stop. Car fails to automatically restart, often stalling at intersections and causing a dangerous situation. Car has to be turned off and restarted, a process that can take 15 to 30 seconds. With a brand new battery and/or full charge, the car performs flawlessly. It appears that the electrical demands of the car system exceed the ability of the battery and alternator to meet demand. I currently have an AGM battery less than two years old. We typically have 1 to 3 incidents per month where will forget to disable the auto start system, and the car stalls in busy traffic when at a full stop. We bought the car used in 2017, and this problem has been consistent throughout ownership. Dealer answer is that there is nothing wrong with car.

The transmission warning light and several other unknown warning lights were illuminated. The vehicle was taken to the dealer where it was diagnosed that the transmission needed to be replaced. The vehicle was not repaired and remained at the dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 60,000.

I have owned this car since new, this is not the first time this has happened. The car has an auto idle stop feature. Which when certain contains are meet and the car is at a stop it will turn off the engine. When the brake pedal is released, (and from other factors) the car will restart the engine so driving can resume. The issue that I am reporting is that the car does NOT restart, the engine is dead. The driver has to press the engine start button a few times while trying to get the car started. This has happened to me more than 6 times over the life of the car. In each situation replacing the battery resolved the issue.
