While driving on the freeway/highway my vehicle went into limp mode and shifted into neutral. My vehicle would not allow me to shift gears and the car would not let me accelerate anymore. I had to think quickly and move out from upcoming traffic. With little speed I had on my vehicle I could only shut down the car and wait for a tow truck. This happened to me twice in 2020 and the mechanics could not find any issue or replicate what had happened. They said this was a software issue. I was still scared to drive my car thinking this would happen again. Then 2 years after ( 2024) again this happened and it was when I was on the freeway. Luckily I was on the left side and was able to stop on the shoulder but stressing out and still traumatized from what occurred 2 years ago. I took it to the dealer and same thing they could not replicate the issue and did re programmed the software. I believe this car is not safe to drive at all knowing this can happen again and again at random times. The attached document is what the dealer gave me stating this remedy was done to the vehicle. This need to be investigated.

While driving approx 65 mph on a freeway the vehicle placed itself into neutral and decelerrated as multiple warnings flashed across dashboard... -??Emissions System Problem-??, -??Transmission System Problem-??, -??Electric Parking Brake Problem-??. I was able to pull off to the side of an exit ramp but once I put the car in PARK I could not shift into Drive. I could not safely drive/manuever my vehicle to a safer area putting myself and child at risk of being hit. I turned the car on/off multiple times to attempt to shift into Drive, but to no avail. I called the nearest Acura dealer which was in the next town over from where I was stranded. After many failed attempts I was able to put the car in Drive and move my vehicle to the closest road and off to the side but with the warnings still flashing. The last successful attempt I was able to put the car in Drive again and without any further warnings flashing on dashboard. Drove 20 minutes to the nearest Acura Dealer and was charged $300 for the diagnosis and update of 3 systems. Informed DTC Code P0657, actuator supply voltage circuit/open, was found prior to system updates: Transmission Control Module Update, PGM-FI Update, and ABS System Update.

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.

- Hayward, CA, USA

When driving on a windy road around 40mph the car went into limp mode causing the car to suddenly decelerate to 5 mph which nearly caused an accident by the car behind me. The car then started displaying multiple error codes on the dash (electric parking brake problem, emissions system problem, brake system problem, brake hold system problem, vehicle stability assist problem, hill start assist problem, lane departure warning problem).

- Fremont, CA, USA

After a traffic light stop, I accelerated and the car lost acceleration, then the check engine turned on. I pulled over and had no response from the accelerator. Check engine was flashing. I turned off the car then turned it back on, and problem was gone acceleration came back. I merge into my lane again and not even 100 ft when my dash lights came on, like a christmas tree. Every light in my dash was lit. The following are some of the lights that were on. Power steering park check engine adaptable cruise control problem collision sign seatbelt traction control oil light ABS collision light brake system problem acc lkas vehicle stability assist the issue appeared to be electrical since the mechanical parts of the car looked ok. I drove the car home at 55 mph since thats as fast as it will let me drive it. I stopped at a autozone to scan the obd computer and just a misfire on cylinder 2 code came up which is strange that a misfire would cause this problem. No other codes came out. Note: Car had no check engine light on before this in 179,000 miles we have owned it. Went home disconnected the battery then hook it back on. Problem went away. It hasnot happened in 12 hrs. The issue is I dont trust the car anymore. If this would have happened in the freeway 10 at 80 mph with traffic, I would have cause a deadly crash. Then I looked on you tube and there is practically dozens of Acura owners with identical issues, some of them avoided crashes because of loss of power. Dealers cant find solutions, in the comments section all I read is people asking if someone found a solution. Seems like Honda should be doing something about it, to keep their costumers safe. Hope this letter gets to them and NHTSA do something about it, before it takes someone's life.

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.

Car has an auto idle reduction installed to save energy. However, the idle is set so low that when you try to start out after stopping for a traffic light, the car stalls continuously.

- Bath, PA, USA

The car nearly stalls, rolled back 3-4 feet prior to restarting after the idle stop had in- gauged. The transmission shifts from 1-4 like someone who never drove with a clutch, even though it is an automatic. It hesitates and nearly stalls when doing slow maneuvering in and around parking lots and slow traffic. I have nearly had accidents due to the hesitation in traffic. When using cruise control out on the expressway, the car will not maintain its set speed on a downhill grade, it gets jerky and increases speed as much as 10-12 mph unless I ride the brake. I have had it back to the dealer twice now, the first time they did all the updates on the computer and fuel pump...its just as bad if not worse. The car is not safe and should have a complete recall!!! the next questions ask for a specific time and date...this is ongoing and has been happening since I purchased the car in January.

- Lake Ozark, MO, USA

New car purchased in 2015. Currently has about 23K miles. Error lights flash on dash including "transmission system problems, blind spot info system problems, vehicle stability assist problem, all wheel steering problem, forward collision warning problem, lane departure waring problem". this is the third time that it has happened. First time, no video evidence of it but we did take it in to Acura to look. No issue found. Second time we had a video, they did a software upgrade. Now again. Along with this, car had a transmission replaced, steering rack and pinion, sub frame, power steering assembly, list goes on.

Can you please investigate the 2015 Acura Tlx with the 9sp transmission? there is unintended acceleration when slowing down, unanticipated surging, and unexpected hesitation when attempting to accelerate. This is a known issue within Honda but there has been no recall or public fix from Honda. I included the purchase date of the car but the above happens at various times. acurazine.com/forums/5G-Tlx-problems-fixes-420/9at-hard-shift-1-2-2-3-A-919230

Yes, you guys are on point! I had my 2015 Tlx V4 advanced pack. And every single complaint I read on here I have! this is very nerve wrecking! I took in my Acura two weeks ago to sherman oaks center Acura, where I originally purchased the vahicle and explained everything that I was experiencing; E.I. jerks, sudden revs, delayed upshift/downshift. The repair center personnel advised me that the vehicle just needed a "simple software update" and that not to be alarmed because Acura will have future updates. So when I went to pick up my car I noticed that the car felt as though I was driving my girlfriend's 10 year old corolla. The car is a F*** piece of S*** I tell you! it lags more and he vibrates too much! this is a safety hazard!

When driving at approximately 40 mph the car suddenly accelerates. I first noticed problem when coasting downhill, but now occurs on level highway also. Also there are periods when one tries to accelerate from a stop or from reverse to drive that the transmission hesitates before shifting into gear. At that point the engine has revved up causing the car to lurch forward when the gear does engage. Additionally even after a recall, the parking gear slips allowing the car to roll down hill. These problems have resulted in near accidents. Updated 11/18/15

I leased my Acura Tlx V6 advanced 2 wheel drive starting in September 2014. Right away, within the first week I started noticing performance issues. This vehicle has an extremely hard shift between 2nd and 3rd gear, causing the car to lurch forward unexpectedly. It is particularly noticeable in "sport" mode. It happens more consistently in stop and go traffic, which coincides with a situation that allows for less reaction time. It also has serious acceleration hesitation throughout all speeds. There have been multiple situations where while merging in traffic or accelerating onto a major highway I have almost been hit because my vehicle was unresponsive. My car has been into Acura twice so far for this issue. The first time I was told it was a "known" issue but there was no fix. The second time I took my car in for the safety recall Acura "changed out the transmission fluid" which was supposed to help - and it didn't. I have another appointment next week for the same issues. Acura client care acknowledged that this is a known problem but that Acura corporate does not have any solutions and it must be taken up with the dealership. The dealership just acknowledges the problem and says to take it up with Acura corporate. This is a dangerous driving situation and I do not feel safe in this vehicle. Acura obviously rolled this car out of the factory knowing they had issues (hence their launch delay in the first place) but were willing to take advantage of the consumer and had no concern for their customers' safety. Buyer beware - do not purchase a Tlx.

The vehicle was not taken to the dealer or diagnosed. The manufacturer was not made aware of the failure. The approximate failure mileage was 10. Updated 4/20/15 the consumer stated when the vehicle was warm, it accelerated when down shifting and the RPM's would to 200-300. Updated 04/23/15

This vehicle often hesitates or has a loud noise of the transmission sounding like it is trying to shift into a gear it shouldn't. both of these occurrences happen when moving from a stopped position. Car does not move for a couple of seconds, in the latter case or is moving away from stopped position in the former case. Every time this happens the vehicle in back of me thinks I am moving forward (which is not happening) and proceeds to move almost rear-ending me. It is just a matter of time. This happens when the vehicle is cold/ hot.
