NHTSA Complaint #11574874 — 2024 JEEP GRAND CHEROKEE 4XE

This is a followup to complaints 11574396 & 11574483. I was advised by service that the vehicle passed an inspection and it was ready for pickup. I went to the service department to pick up the vehicle. The service manager advised me that the vehicle was properly wired, and that he believed the problems that I have experienced were resolved through software updates. He also advised me that he believed the issue of the vehicle not accelerating past 29 mph was due to the vehicle being placed into manual mode through the vehicle's paddle shifters, because 29 mph is the limitation for 1st gear. I advised him that I never used the paddle shifters, but he insisted that I must have hit them by accident. He also advised me that in the event the vehicle enters manual mode, I can exit that mode by holding down the right paddle. I took back possession of the vehicle and began to drive home. I did not even make it half a mile before the vehicle once again began to experience serious malfunctions. The engine once again shut off while driving. I pulled onto the swale. Once again, the "D" was blinking on both the shifter knob and the driver info panel screen. There were numerous error messages and icons displayed. This included the check engine light, battery warning light, check hybrid electrical system light and warning (wrench with lightning bolt), and service electronic stability control warning. The vehicle also stated that the auto emergency braking system was engaged in active braking, despite the fact I was not near any other vehicle or object. There were other warning messages that displayed but that cycled through too quickly for me to read or photograph them. After restarting the car, once again, the vehicle would not accelerate past 29 mph. The screen showed the vehicle was in manual mode, in 1st gear. I could not return to manual mode. The service manager has indicated that engineering technicians must be brought in.
