NHTSA Complaint #11246629 — 2017 JEEP CHEROKEE

ON NUMEROUS OCCASIONS WHEN I START MY VEHICLE THE ALL OF THE LIGHTS ON THE SHIFTER LIGHT UP. THE DASH WILL THEN SAY THE MESSAGE "SERVICE SHIFTER NOW". THE ONLY WAY TO CLEAR THE MESSAGE IS TO SHUT MY CAR OFF AND RESTART IT. SOMETIMES 3 OR 4 TIMES IN A ROW. LAST TIME IT HAPPENED I HOOKED UP A TESTER TO SEE IF IT GAVE A CODE. IT GAVE CODE U0164 "LOST COMMUNICATION WITH HVAC CONTROL MODULE". I SHUT IT OFF AND RESTARTED AND THE DASH SAID "NO BUS" AND I HAD NO CONTROL OVER MY FRONT WINDOWS, RADIO, TOUCH SCREEN OR HVAC. MY HEATER WAS ON HIGH AND SO WAS THE FAN. I COULDN'T DO ANYTHING TO CHANGE IT. AFTER I SHUT IT OFF FOR APX. 15 MINUTES OR SO IT CORRECTED ITSELF. SPEEDS VARIED FROM 0 MPH UP TO 60 MPH. SOMETIMES HAD TO DRIVE WITH THE MESSAGE BECAUSE IT WOULDN'T GO AWAY AFTER RESTARTING THE VEHICLE SEVERAL TIMES.
