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.

The contact owns a 2015 Acura TLX. The contact stated while driving 60 mph, the vehicle decelerated inadvertently. The contact pulled over to the side of the roadway and restarted the vehicle and the vehicle operated as designed. On another occasion, while driving at an undisclosed speed, the vehicle inadvertently shifted from drive to neutral. The vehicle was restarted however, the failure recurred. Several unknown warning lights were illuminated. The contact took the vehicle to a local dealer who inspected the vehicle but was not able to diagnose the cause of the failure. The vehicle was not repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 73,000.

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

My car completely lost all power and died on the freeway. All the dash board lights came on and I could break or steer and the car was stuck in Neutral.

When the car running on normal speed and press brake for slowing the car try to jump and the RPM freaks out

The vehicle unexpectantly shifted out of drive to neutral while going up an inclined road at about 45 mph. The background of the neutral gear "N" indicator was yellow. Engine power was lost for approximately 5 seconds and then recovered when the transmission shifted back to drive without any intervention. I don't recall seeing any kind of error message when this occurred, but it is possible it could have been missed while I was frantically trying to figure out what was happening. After researching this issue on the internet, I discovered that there was a safety recall (16V640000) for a similar consequence which only applies to select vins. My particular VIN is not part of the safety recall. The performance of the transmission has always been worrisome. I am the original owner. The transmission rarely shifts smoothly going from 1st to 2nd and 2nd to 3rd gears even after multiple attempts to get this corrected at my auto dealership. It is still not satisfactory, and this latest episode just adds to my consternation. Acura has provided an extended warranty for transmission failure if it is related to the atf warmer. I expressed the issue and my concerns with Acura. The case number is not officially open until the issue is diagnosed by an Acura dealership.

- Tucson, AZ, USA

The contact owns a 2015 Acura Tlx. The contact stated while the vehicle was parked on a slight incline, the vehicle started rolling backwards. The contact jumped back in the vehicle and engaged the parking brakes. Afterwards, the contact attempted to shift the vehicle into drive however, the transmission failed to respond. The contact was unable to shift the vehicle into drive or park. An independent mechanic was called out to the residence to diagnose the vehicle. The mechanic retrieved a temporary fault code of the transmission. The contact was informed that the transmission wiring harness needed to be replaced. The vehicle was not repaired. An unknown dealer and the manufacturer were notified of the failure. The approximate failure mileage was 95,000.

When accelerating the car trips into neutral and will not let me continue accelerating. I can push the pedal all the way to the floor and nothing will happen. The only way it trips out of neutral is to release the pedal and then push it again. This happens when already driving around 10-30mph not from a stopped position and was on city streets. It does also happen when turning.

While driving I noticed that my car didn't seem to shift correctly. I pulled over and accelerated again. Got to my destination and noticed the car wasn't moving harldy as I pulled up to park. Once I parked, I put it in reverse to pull up again and it was making a loud noise and jerking when I put it in reverse. I did this like 3 times to try and figure out what was going on. After about 4 hours I went to leave my destination and it shifted into reverse just fine. I was relieved until after about 5 minutes of driving and then every light illuminated on the dash and the car wasn't accelerating as it should have been. The RPM's were going up but car was barely moving. I made it home but now sick to my stomach because I have no idea what this could be. Not sure if it needs to be towed to a shop or if I can or should drive it if possible.

This vehicle is so unsafe. I had lots of different situations happen and when I take it to the dealership they check it and say it's fine ! the vehicle stalls and hesitates and I get sensors going off constantly including the brake sensor when there is nothing in front of me for it to go off. I've had the vehicle go in park by itself while on a light. The vehicle doesn't start and always needs a jump I got the battery checked multiple times and the dealership told me my battery is good and I have to charge it. I believe there is an electrical issue with this vehicle. My vehicle only has 30,000 miles I have all my maintenance done at the dealership on time I purchased this vehicle thinking it's reliable being I'm a mother of two kids!

- Tinley Park, IL, USA

After replacing my battery on my 2015 Tlx I started receiving warning codes saying emission system problem and electric parking brake problem. I went to 3 different Acura dealerships for a diagnosis and was given a different diagnosis from each dealership. I first seen the codes as I was entering the expressway at approximately 35 mph 1 week after getting a new battery.

Transmission jerks when driving its totally un safe to drive on the highway.

- Chicago, IL, USA

On June 7th 2020 I was driving my car, it started to shake. As I started to drive back home to see what was going on all the problems showed up in the screen. I had to drive with my emergency hazard lights on because I couldn't go more then 25 mph or it would shake even more. We have at least 12 pictures of what's showing in the screen. We are only able to upload one.

Now that the vehicle has crossed 30K miles the power train is now not as responsive and I'm some situations aggressively jerks the car forward when downshifting when the vehicle is coming the a stop. This also occurs when the vehicle is going from a compete stop, the vehicle jerks back as the transmission up shifts for the next gear.

While driving straight or turning left or right, occasionally the car will fail to accelerate when the gas pedal is pressed. The engine appears to go to an idle speed for 1-2 seconds and then the car accelerates. This has been brought to the attention of the local dealer multiple times but they (and Acura) are unable or unwilling to fix this problem. I have sent them video of the tachometer dropping to ~900rpm when this happens. They state there are no error codes or information that indicates anything is wrong. This seems to match safety problems 11121786, 10775339, 10695446, and 10694812. Another problem the vehicle has is a shudder in the transmission at certain speeds. Shifting to a different gear makes the shudder go away. Dealer states this is just how the transmission works. Transmission was replaced around 51K miles. Old transmission did not have this problem. Dealer said a fluid change might help. It did not.

The vehicle is shaking at highway speeds, I have replaced the tires, brakes, rims and the vehicle I am told from the dealer that my vehicle doesn't apply to known issue and there's nothing I can about it, I have had it balanced and road forced tested with no relief it's a concern as the vehicle instability has caused for new hubs and already on a vehicle less than 50K on the mileage
