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.

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. Not sure why my 2018 RDX is different from other 2018 RDX models that were recalled.

Vehicle began hesitating when starting, but not all of the time. One day after refueling it would not start. Lights on the dashboard flashed and flickered and the keyless start button made a clicking sound, but the vehicle would not start. Vehicle was towed to the nearest mechanic. The next morning the mechanic started the vehicle and found nothing wrong. Mechanic kept the vehicle for a couple days and the problem reoccurred. Vehicle will not start. Computer diagnostics shows the 2018 Acura RDX Control Unit part number 38320-TX4-A31 is faulty. This part is backordered and likely will not be available in the near future. The intermittent starting failure poses a safety risk and could leave a driver stranded.

Hard, jerking shifting at approximately 20 mph. Potential problem moving in close traffic such as from traffic light or entering traffic. 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. I-??ve found the problem mentioned a on the internet a number of times., but the mechanics were not aware of any transmission problems. I find it hard to believe Acura isn-??t aware of the problem and how to fix it. The problem is intermittent and has been happening for over a year. The problem still hasn-??t been diagnosed. I-??m concerned my transmission will be damaged if the problem isn-??t fixed. Most recent shifting problem was 4 times in about 30 min starting at ~9:30pm on July 21, 2022

Have had this car a year. Withing 6 months shifter would not shift back to park and couldnt turn car off. Dealer found acorns jammed in transmission somewhere felt to be due to squirrels or other rodents. This month emissons light came on. Found fuel line leaking due to animals chewing on it. Not covered under warranty. $1100 to fix. I feel the engine housing is not well sealed allowing this to happen have never had this issue with any other cars which have been parked in same place for long periods of time. Feel it should be fixed under warranty to prevent it from happening again. Vehicle sits outside driven twice a week.
