NHTSA Complaint #11486697 — 2019 ACURA RDX

On 9/22/22 travelling on I-290 near Boylston, MA I was passing a large tractor trailer in the far left lane going up a hill. It was and had been raining very hard for at least the previous hour. When I stepped on the accelerator to increase speed, the car suddenly decelerated to about 20 mph and the check engine light began flashing. I was able cross all three lanes in very heavy traffic to the shoulder. I then slowly made my way off the interstate to a gas station right beyond the exit. My passengers and I were very concerned about the suddenness and the abrupt reduction in speed on an extremely busy roadway. A call to the nearest Acura dealer service department confirmed he had seen nearly the same symptoms the prior week under similar road conditions and the same model car as mine. He found no codes on the other car. I also notified Acura customer service who confirmed the existence of a Service Bulletin on precisely this issue (flashing light with loss of power).
