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.

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).

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 the federal safety agency 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.
