Exterior lighting

33 reports1 crash2 related recalls
“There is a water seal leak around the driver side headlight. I have photos showing proof of standing water. It has now caused the headlight, left turn signal, and drivers side brake light to fail. My passenger side headlight is doing the same. I have no headlights, no driverside lights period. I drive 2 children around in this car and it's gotten very dangerous. I contacted GM, and the local dealership and they won't fix it. I'm a [XXX] and don't have the $3200-$5000 I was told the repair would be. It is a problem in certain GM models, Cadillac Srx 2010-2015 having the same issue and the recall being fixed for those drivers. So, I have no choice but to drive around with no headlights, no left blinker, and no driver side brake light with two you children. I have to work and have no other options. It's a catastrophe waiting to happen, I live in the metropolitan area of Atlanta, Georgia. Please help me with this, I am terrified to drive this car around. I've had two people flag me down at a red light to let me know my brake light is out which is terribly dangerous and if it starts raining while I am out I have no headlights. This has become an emergency situation…”

“[XXX] my car failed to let me use the brake, i was going about 45mph and when i went to apply brake pressure the pedal was so stiff i couldnt use the brake. Causing from end collision, when i made a trip to springdale to have my car inspected it didnt make it, started backfiring and dying around 65 mph then the motor blew, it had some issues starting but nothing like what happened within that few seconds. Im out of a car now because it drove perfect and i never have to give it thought.”

Service brakes

8 reports1 crash
“BRAKE PEDAL WILL NOT RETURN FULLY AFTER IT IS APPLIED WHEN IT IS WARM AND HUMID. CAUSES BRAKE PEDAL TO STICK AND NOT ALLOW CRUISE CONTROL TO BE SELECTED. THE STUCK PEDAL ALLOWS THE CAR TO BE STARTED AND PLACED INTO GEAR WITHOUT A FOOT ON THE PEDAL. DID FIND THAT GM HAS NOT ONLY ISSUED A TECHNICAL SERVICE BULLETIN FOR THE DESCRIBED ISSUE BUT HAS ISSUED MULTIPLE REVISIONS TO COVER ADDITIONAL VEHICLES EACH TIME. GIVEN THAT THIS IS A WELL KNOWN ISSUE BY THE MANUFACTURE, THIS SHOULD WARRANT A SERIOUS LOOKING INTO A RECALL ISSUE. TSB # PIC5692D DATED 05/11/2018 IS THE FOURTH REVISION AND THE ORIGINAL TSB PIC5692 IS DATED JULY, 2012. TSB PIC5692D EVEN STATES THAT A PRODUCT REVIEW IS REQUIRED. *TR”
