Open the full vehicle complaint log (all categories)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. Again this was a serious fuel engine issue that if I’d been passing a car on a two lane road into oncoming traffic could have been deadly
