NHTSA complaint #11495022

Owner complaint summary

I have a 2021 RDX. Was on the interstate moving at about 70 MPH coming back from Missouri. Raining. Lots of semis creating huge following misty, hard to see rain. Decided to accelerate to pass a couple. Car nearly stalled and acted like it had lost a cylinder's worth of power. Turned on hazards, slowed, pulled over and lifted the hood hearing all kinds of unusual noises. Shut the car off and restarted. All was well. Turned all lane-keeping, etc. off including cruise. Drove the last 100 miles or so without incident. Called dealer and was told likely didn't pull a code. Don't worry and keep driving. Said to make sure front of car was clean. Duh!! I keep my ride spotless (unless driving in the rain). Called CA's Acura line. Absolutely no help. 2 different females had no idea what limp mode was. Read quite a bit since then finding out it could be the result of many things including problems that could damage the motor and/or tranny. WOW!!! Had never heard of "limp mode" before. Nice that no info on this possible problem was anywhere in any user manual. Car has performed flawlessly ever since. So far, I guess the rain had interfered with the "radar" system and confused the computer. I'm thinking about buying a 40 year old car that doesn't have any of the modern computers etc. Later found info regarding TSB 20-053 which explains the problem and proposed solution. 06-26-2022 06:52 PM
