NHTSA Complaint #11550408 — 2022 ACURA RDX

Vehicle has lost power and gone in to ‘limp mode’ numerous times when accelerating, reducing speed to 25-30 MPH. The engine runs extremely rough during this time and will not rev up. This has caused traffic behind me to slow down immediately to the point I’ve come close to being hit from behind. It has also lost power without warning several times when driving at approximately 45 MPH, reducing speed to 30 MPH instantly, after which the engine check light illuminates, causing traffic behind me to slow down until I have a place to pull off the side of the road. The first incident was 10/20/2022 at 1,828 miles. I brought the vehicle to an Acura dealership to have it checked out and the service department couldn’t find the problem. The last time I had it in for service was 10/04/2023 at 8,379 miles, and again, the service department couldn’t identify the issue and told me to set up an appointment for overnight so they could try and replicate the problem. In all instances, when the vehicle is turned off and restarted, the check engine light goes out and it runs fine.
