“After a stop at the va welcome center, I attempted to merge into traffic on I-81 north. The vehicle suddenly lost power and the check engine light came on. I was able to move to the shoulder and avoid being rear ended. The vehicle was towed to duncan Acura. They determined multiple cases of similar models had the same complaint. This is a known issue that has the potential for loss of life and should be remedited immediately. One online source said Acura has known of this problem since 2016.”

“On 7/22/2020, I was entering the mass pike from I-495 outside of boston. I accelerated to get around a box truck and suddenly the engine light started flashing and the car started to lose power. No matter how much I stepped on the gas, the car kept losing speed. Thankfully, I was near a rest stop and was able to pull to the shoulder (from the middle lane) and had enough momentum to get the car in the parking lot. Thank goodness it was nighttime and with covid, there aren't as many cars on the road. …”

“I drive a 2020 Acura RDX having 1,840 miles. While driving on the highway on two separate occasions (approximately several months apart), my car had suddenly decelerated. My foot was not on the break at all. The car would not accelerate when applying my foot on the accelerator.
