NHTSA complaint #11171119, filed 2019-01, 8,500 miles“I am unable to find a dealership that will perform the repair, please help. They all say they are short or parts and are only fixing vehicles experiencing issues. I lose power when accelerating all the time but this apparently is not enough.”
NHTSA complaint #11628999, filed 2024-12“My 2018 RDX has started to jerk when I stop and then restart. I have noticed some hesitation and a bit of jerky driving but today it was very noticeable. I could barely go above 40 miles an hour after I started driving after a stop light and the car was very jerky. It seems to be either a fuel pump or transmission issue. I am going to check with the RDX dealership where I bought the car in 2018 but I wanted to report the issue. I also looked up the VIN on my car for a recall and the system said my car had not been recalled. …”

No diagnostic warning/error lights. I’ve taken my car to Crown Acura 14080 Brookpark Rd, Cleveland, OH on July 11, 2022 for diagnosing and servicing the problem. It’s an intermittent problem so they couldn’t replicate so they couldn’t diagnose the problem. They flushed and changed the transmission fluid, bc and did a complete servicing. The service report does not show the transmission fluid filter was cleaned or replaced. …”
