NHTSA Complaint #11427194 — 2019 ACURA RDX

My wife purchased this car about one month prior to this incident. It was presented as a Certified Pre-Owned vehicle. While traveling on the PA turnpike, the car suddenly and with no warning went into "limp mode", with only enough power available to maintain about 20 mph. The "check engine" light came on, and we continued at about 20 mph on the shoulder, hoping to come to an exit. After a few minutes and no exit in sight, we stopped and turned off the engine while considering what to do next. When the air inside of the car became uncomfortably warm, I turned on the engine so we would have a/c. Immediately, it became apparent that the engine was working normally: no "check engine" light, plus other positive indications. We resumed our trip, arriving home safely. Our safety was at risk since the engine lost power with no warning whatsoever, and occurred while we were in a travel lane. As of this report, the car has not been taken to a dealer.
