NHTSA Complaint #11436634 — 2021 JEEP GRAND CHEROKEE

Car does not down shift properly from 5th to 1st gear or shifts hard into upper gears causing the car to jerk or jolt into gear. The Sport mode engaged the steering becomes sloppy loose and car becomes unstable to maintain control, unless returned to auto mode. Dealership techs claim they cannot diagnose because the computer system does not show any error codes the repairs they have done are computer updates which were supposed to fix the transmission issues it did not. FCA Stellantis refuses to acknowledge the problem and has told the dealerships to not pull the car in for any work unless they can show computer code failure or they will not compensate the shop for any warranty work. Jeep knows there are many issues involving this model including engine shutting down while in motion and again refuse to warn Jeep owners this particular model puts them at serious risk for injuries and death if car fails while its being operated on freeways. Another major issue concerns usage of ACC the car can slam on brakes Inadvertently, or puts the car into neutral mode while traveling at speed limits up to 70mph. I have had my car in the shop over 6 times out of service for 18 days for the same problem, the dealers are being forced to cover up for the manufacturer for a faulty unsafe vehicle. The Technicians going so far as to blame the owner for operator error, yet the problem remains. This car is a menace and should be recalled.
