NHTSA Complaint #11254100 — 2017 JEEP GRAND CHEROKEE

WHILE DRIVING ON A HIGHWAY AT 60 MPH MY VEHICLE STARTED FLASHING EVERY POSSIBLE WARNING LIGHT. AIRBAGS, ABS, SLIP CONTROL, CRUISE CONTROL ... EVERYTHING. MOST CONCERNING WAS THE 'SERVICE SHIFTER' ALERT; THE PRND LIGHTS ON MY SHIFTER PANEL ALL STARTED FLASHING AND THE CAR (AUTO TRANSMISSION) WAS STUCK IN ONE GEAR AND WOULD NOT SHIFT. PULLING OVER AND RESTARTING THE VEHICLE WOULD 'FIX IT' FOR 10-15 MINUTES UNTIL IT ALL HAPPENED AGAIN. ENGINE WAS MAKING AN AWFUL LOUD NOISE SO I PULLED OVER AGAIN. THIS TIME AFTER TURNING IT OFF THE VEHICLE WOULD NOT START AT ALL. AFTER 30 MINUTES IT STARTED AND I WAS ABLE TO DRIVE TO A TOWN FOR THE NIGHT. THE NEXT MORNING I WAS ABLE TO START IT AND DRIVE IT IN 1ST GEAR (WHERE IT WAS STUCK) TO A JEEP DEALER. THERE IT SITS AS I TYPE. I HAVE SEEN MANY IDENTICAL ISSUES REPORTED BY JEEP OWNERS ON INTERNET FORUMS AND MOST WORRYINGLY, JEEP DEALERS DON'T SEEM TO HAVE A CLEAR ANSWER. THEY'RE COMMONLY REPLACING THE SHIFTER WIRING HARNESS BUT THE PROBLEM RETURNS FOR NEARLY EVERYONE. THIS INCIDENT STRANDED ME IN THE MIDDLE OF THE NIGHT, IN THE MIDDLE OF NOWHERE, AND LEFT ME VERY WORRIED ABOUT MY SAFETY. WHATEVER IS WRONG WITH THE VEHICLE HAS CASCADING ERRORS THAT AFFECT HEADLIGHT OPERATION (MY HIGH BEAMS WOULD NOW WORK), SLIP CONTROL (IT BECAME NON FUNCTIONAL EVEN IF I OVERRODE IT), WIPERS (IN MY CASE THEY CAME ON WITHOUT ANY RAIN AND I COULD NOT TURN THEM OFF...THEY COULD JUST AS EASILY HAVE NOT FUNCTIONED IN A DOWNPOUR CREATING A SAFETY HAZARD), AND BRAKING (THE BRAKE PEDAL WAS ROCK SOLID AND NOT WORKING PROPERLY).
