Interstate 10 near Live Oak, Florida. Conditions were light fog and roads were dry. The previous day we drove about six hours, two or three times in very heavy rain. We were driving eastbound (two eastbound lanes) in the right lane. We were approaching a Semi-trailer followed by a medium-sized box truck and switched to the left lane to pass both vehicles. Another vehicle was approaching from behind in the left lane and I "floored" the accelerator pedal to quickly pass the two trucks. The RDX downshifted as expected and the engine revs increased briefly, but suddenly the Check Engine light started blinking and the car lost power and went into Limp Mode. Pressing the accelerator to the floor made little difference. Instead of quickly passing I was only able to get past the two trucks at a slow rate with a line of vehicles growing behind me. Eventually I was able to get past the trucks, switch lanes and quickly move over to the breakdown lane. If there had been heavier traffic, this could have easily resulted in a serious accident. I restarted the vehicle and resumed our trip without further incident. This is a known issue supposedly addressed by Acura via TSB 20-053 for some model years and reported on Acura enthusiast web sites. I had the same experience with my previous 2020 RDX after having the TSB completed, I filed an report for that incident under NHTSA ID Number: 11522688. There are hundreds of reports for this issue for all 3rd Generation RDX model years, 2019-2024, on the NHTSA site I brought the vehicle to a dealer on July 5, 2024. Unable to duplicate. No codes stored (as has been stated on other reported incidents). No water intrusion to coil packs or plugs and no fouling or damage to plugs. I cannot trust a vehicle if I have to be concerned about whether or not I should pass another vehicle and how hard I can press the accelerator. This is an ongoing issue with the RDX that should be investigated.
