I was driving down the freeway, in a new 2021 Acura TLX with 2000 miles on it. It was raining when I went to switch lanes and floor it to pass another car and the check engine light came on and the power dies and speed dramatically slows down and I'm unable to accelerate. The check engine light is flashing and the car will not reach 40mph. Again I'm on the freeway. This was a very dangerous situation. There were no warnings leading up to this catastrophic fuel/engine issue. I took the car to the Acura dealer who said there had been reports of issues related to water getting into the car's intercooler for the turbo causing the car to misfire and then going into "safe mode" with a flashing check engine light. They installed Acura SB 20-053 PGM-FI update. I'm picking the car up on 2/6/22 and hoping the issue is resolved. …

I was driving down the road out of town about 3 hours away from home when I heard a beep and car started to stop, later finding out it was going into "limp mode". It was then towed to a car shop which was not any help, they stated that they didn't know what was wrong with it and that I needed to take it to Honda down the road 2.5 miles that it just needed a system update; very mistreated and rude not offering towing service suggestions or anything told me I can still crank and drive it just not fast. I got into my car and drove it to Honda which would not go over 15mph trying to get there before closing on a Friday afternoon. …
