NHTSA Complaint #11441603 — 2021 CHRYSLER PACIFICA

Component: The Low gear does not function properly. When the car is in Low on a steep grade it allows the engine to rev up to 6,000 RPM before shifting into second gear. On a hill, the RPMs rev up quickly and the car’s momentum is not properly arrested. In practice, this car does not have a true Low gear. L1 acts more like an L4. Safety risk: We use this car in the mountains of Virginia. We have an AWD model, which performs great in the snow. However, with no hill descent feature and a malfunctioning Low gear it is dangerous to drive the car in the mountains. Driving down a snowy mountain with no low gear is a major risk. Service center: Yes, the problem has been confirmed by my local dealer, both in my car and in a brand new 2021 Pacifica. Inspected by others: No. It was confirmed by the service manager of my local dealer only. I emailed Chrysler but have not received a response. Warning lights: No. The vehicle is performing as it was designed, there are no malfunction lights. According to the dealer service manager it is a transmission problem. He thinks it is a problem with the computer system as well as the ratios for the transmission system. After confirming the problem in my car we tested a brand new 2021 Pacifica (9 miles driven). Our first time down a hill it worked perfectly, the RPMs held below 3,000 and the low gear slowed our descent. By our third attempt, the RPMs were revving to 6,000, and the low gear “grip” was gone. The service manager conjectured that there is something in the computer system telling the Low gear to act like that. Which doesn’t make any sense because revving the RPMs up to 6,000 is not healthy for the engine. I have a video of the problem but it doesn’t allow me to upload it below. Thank you!
