I recently got my rotors replaced and the car stutter while braking. Also, this happened before I replaced rotors.. the transmission is slow and won't shift to merge highways. I don't know if its the transmission or the brake lines.. I guess it's the transmission trying to drop gears for engine braking and it starts stuttering.

Upon braking, when coming to a full stop, the transmission (ZF 9-speed automatic) makes a very hard downshift into 1st gear and causes the car to lurch forward. This issue appears to be worsening over time. The car is becoming more and more difficult and dangerous to drive due to this issue. The car was very recently brought into an Acura dealership (DCH Montclair Acura) to address this issue. They replaced the transmission fluid and conducted a general software update, but this issue continues to persist as before.

The contact owns a 2015 Acura TLX. The contact stated while driving at various highway speeds, the transmission randomly shifted into the neutral causing the vehicle to lose automotive power, decelerate, and failed to accelerate while depressing the accelerator pedal. During the failure several messages were displayed including the "Transmission Failure" message. The vehicle was towed to the local dealer who diagnosed that the transmission shifter was faulty, and a transmission computer software update was needed. The vehicle was repaired; however, immediately after retrieving the vehicle, the failure reoccurred. The cause of the failure was not yet determined. The manufacturer was not yet notified of the failure. The failure mileage was 115,000.

My car shifts itself into neutral automatically at times while I am driving. It has even happened on the interstate. When this happens it also flashes lots of warning signals on the dash and will be stalled for 4-5 minutes, engine will not shut down, just cannot shift into reverse or drive. The Acura dealership had it all day and they were stumped so they did a software update. I have read this exact problem has happened with other Acura's this same year and model and it was crimped wiring harness of the transmission.

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.

I was merging on to the freeway going about 60mph, with traffic right behind me. Car started decelerated and the dash board lit up. A car behind me had to swerve to avoid hitting me. I put on my hazard lights and tried to move to the shoulder the car was only going about 5mph at the time. I turned the car off and restarted to see if it would move, but it was still going about 5mph. After doing this a couple of times I was able to get the car the move at about 20 mph. The dash board is still lit up.

The contact owns a 2015 Acura TLX. The contact stated that while his son was driving at various speeds, the vehicle would shut off without warning. The contact had initially taken the vehicle to an unknown dealer in West Virginia which has since closed, and a software update was performed; however, the failure persisted. As the failure became more frequent, the contact drove the vehicle to another dealer where the mechanic was unable to diagnose the failure. The contact was also informed that the vehicle was not included in NHTSA Campaign Number: 19V060000 (Fuel System, Other) which the contact linked to the failure. The manufacturer was notified of the failure and provided the contact a case number. The vehicle had yet to be repaired and remained in the possession of the dealer. The failure mileage was approximately 28,000.

While driving at 60 mph in left lane of highway, without warning, the vehicle slowed and lost all acceleration and slowed, and then a series of warnings lit up on the screen including: electronic parking brake error, a transmission warning pertaining to the ZF 9 speed transmission that demanded driver to pull over to the side to avoid major damage, and emissions failure warning. Then numerous other warnings displayed indicating collision warning system issues, and warnings that other driver safety systems had disengaged or failed. The transmission automatically switched to neutral (which I could only figure out 10 seconds later) as the accelerator would rev the engine but provide no motive force, making changing lanes across 3 lanes of traffic on a busy highway very dangerous as my car decelerated relatively quickly to fast moving highway traffic. After I pulled over and stopped the car, I tried turning off the car and restarting the car, and the transmission error and emissions system error was immediately displayed and prevented the vehicle from being put into drive. I tried to get a hold of the Acura towing service but was stuck on hold for 20 minutes and hung up. I started the car once again, and no errors were shown. I was able to drive 1/2 a mile and the transmission once again disengaged into neutral and emissions system warning came up again and I pulled over once again. I once again waited 20 minutes and restarted the car and drove 3 miles to a shopping center parking lot and let the car sit for 1.5 hours. When I returned, I started the car and everything seemed fine, and I was able to drive 35 miles home with the emissions system warning and transmission system warning displaying but the car remained in gear. I took the car to the dealer the next day (with the car still covered under extended warranty), and Acura performed a software update (PGM-FI and TCM and PCM Idle Learn updates), for which they initially said I was responsible to pay for.

I bought the car July of last year (2020) and noticed the car was a bit jerky when I accelerated from a complete stop. But as I started to drive the car more I noticed it was jerky shifting from 2nd to 3rd gears. Its a violent jerk. Everyone in the car whiplashes when it happens. When I go downhill and press on the brakes to slow down it gets a sudden burst of speed and doesn't slow down but goes faster even when pushing on the brake. On the dashboard I have multiple lights that won't turn off. The lane keeping assistance, lane departure warning, forward collision warning as well. I havent gone to the dealership or have had checked out by Acura or anyone just yet. But I know other people have the same exact problems and its a real danger to drive and these things happen on a daily basis. Im sure its something with the transmission and something needs to happen because I love this car and worried about safety of me and others out on the road
