Example complaints

“When driving above 65 MPH and passing, my engine has stalled on three different occasions. Once at 1200 miles and the other twice in one day at 4,000 miles. The car obviously loses all power causing me to have to merge right in traffic to the shoulder to restart the car. Each time is was under full acceleration and in high traffic conditions.”
NHTSA complaint #11194613, filed 2019-04, 4,000 miles“I had moved to the left lane to pass a slow moving truck on th pa north east extension. When I had almost passed the truck my engine light began flashing and my car started to decelerate. I was barely able to get over to the shoulder. I had to turn the car off and restart it to get the light to stop flashing and get the car to accellerate. Fortunately it happened before I entered the tunnel.”
NHTSA complaint #11405498, filed 2021-03, 36,800 miles“I was accelerating hard onto a highway on ramp when the check engine light turned on and the car went into limp mode. I drove at 40 miles per hour to the next exit and turned off the car as instructed on the manual. The car returned to normal operation afterwards although special care was taken to minimize strong acceleration.”
NHTSA complaint #11240989, filed 2019-08, 1,100 miles“I reported an issue with my 2019 Acura RDX, where if: engine auto stop is enabled, and brake hold is enabled. On two occasions, the vehicle lurched forward while the brake hold is enabled this propelled me to the side of the intersection today, with a 2020 loaner, it happened again”
NHTSA complaint #11286447, filed 2019-12, 3,000 miles“We have had the RDX for 18 months and have put 5,000 miles on her. During this time the engine has stalled on us perhaps 6 to as 8 times; the stalls have been and worrisome, couple seconds. The stalls have occurred merging on the freeway, at intersections while making a left or just pushing down the pedal when your cruising. We have had several close calls. You don't want to be around heavy traffic when the stall happens. It is dangerous.”
