There are 3 owner-reported engine complaints for the 2023 Acura RDXin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
On October 31, 2024, I was nearing the end of a three hour trip. I was traveling on a rural two-lane highway with a 55 mph speed limit. I had just pulled away from a 4-way stop intersection and was following a single vehicle traveling 40 mph. Once I could see there was a safe distance from oncoming traffic, I decided to pass the slower vehicle. As I moved into the opposite lane and accelerated, the engine lost power and barely made it around the car I was passing. If oncoming traffic had been closer there could have been a head-on collision. The engine light started flashing and I had to keep the accelerator pressed half way to the floor to maintain 50 mph. There was no shoulder on the road and no place to pull over, so I continued for 15 minutes with engine light blinking and struggling to maintain 50 mph. No other warning lights came on and the engine was not overheating. When I reached my destination I turned the engine off and then restarted it. The flashing engine light was gone and the car drove fine. The nearest Acura dealer was an hour away so I took the car to my dealer when I returned from my trip. They test drove the vehicle and called the Acura Tech Line. They could not duplicate the problem. They said they did not find any diagnostic codes so there was nothing they could do. They said if it happens again to bring it back. If it happens again I might not live to tell the story!
On entering the highway and accelerating quickly, engine lost power and car entered limp mode, refusing to exceed 60 MPH. Also, check engine light began flashing. Very dangerous situation in heavy traffic all going over 70 MPH. Exited at next exit, shut down car, then restarted with no further issues.
Fast blinking engine light, and car not able to accelerate past 40mph. Was informed by dealership that it was possible water intrusion but had no guarantee or adequate mitigation strategy to ensure the problem would not occur other than indicating it is normal behavior to expect during heavy down pour!! The following codes were presented to dealership service dept after performing diagnostic: P0300, P0301, P0304 Car has 10k miles and it’s a 2023 RDX A Spec. Another issue happening with the car is an intermittent “Brake Failure. See Dealership” message on the dashboard. Was told it’s expected behavior for this to sometimes happen and due to no permanent code present, they cannot repair or identify the issue. I guess the breaks have to fail while driving before they actually prevent an accident from happening?!!!
