2018 Acura RDX: hesitation when accelerating

Filed Oct 9, 2024 · Engine, Fuel system · VA

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.

The car hesitates to start and while driving jerks at around 20mph. This happened a few times in the last year. When taken to dealer, because they could not reproduce incident, said it can’t be diagnosed. I told them it jerks when accelerating at around 20mph and keeps doing it every time I have to stop at light and go again.

There is acceleration hesitation every time when I'm driving. The car seems to "catch" as it's accelerating and is very "jerky". The issue has gotten worse over time. I take my care to Acura for a second time next week to see if I can get it officially diagnosed; however, I've already been told there are no parts available and I'll just be "put on a list". This recall was announced in Dec 2023 and it's now Sept 2024 so I don't understand how this delay is acceptable. The additional details that I need to provide below only allow me to enter one date. I started noticing the issue last year and as I said it's gotten progressively worse. I last drove yesterday so used that date but it's been going on for about a year.

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.

Stopped at a red light, I was waiting for the opportunity to make a right turn. When the right lane was free of traffic I began to turn into that lane, but an approaching car made a lane change as it neared the intersection, and I let my foot off the accelerator for a split second before I realized I was too far into the lane. I tried to accelerate quickly to avoid getting rear-ended, but my Acura RDX's transmission hesitated and the engine raced in neutral. Fortunately the appoaching car was able to swerve back into the left lane and thus avoid hitting me. Not all drivers are as attentive as that driver had been, and I felt very fortunate to have not been hit. My husband and I have taken the car into the dealership multiple times, but they are unable to duplicate the transmission problem, though it continues to occur. We feel this random hesitation in the six-speed transmission during a crucial accident avoidance manuever could easily result in a collision.
