My Rdx went into 'limp mode' (30 mph max) while on I-75 southbound in moderate traffic near macon ga at 10 am trying to accelerate to speed limit (70 mph) from 50 mph after being cut off by an inattentive driver. Engine malfunction light was blinking. Got to right shoulder safely and turned engine off. Restarted engine and completed another 400 miles at interstate speeds without incident. Acura dealership could not replicate problem, nor were any codes stored on obd. I was told by Acura service writer to monitor engine performance and report any reoccurrences. Several Acura Rdx owners are reporting same problem on a popular Acura online forum. One member stated the Honda civic type R is experiencing the same problem. This is a very serious engine and/or engine management design problem necessitating an immediate investigation and recall, in my opinion. Right now I feel my Rdx is unsafe at any speed with the potential of causing serious injury or death.

The engine shut down in the middle of an intersection in traffic, while in motion. The car refused to start up again, indicating a transmission failure. The car also refused to shut down, and the electronics are confused. This is the third incident that I had with this vehicle.
