2012 CHEVROLET SILVERADO 1500 Electrical System Problems

I got the code p2138 and I’ve had it inspected and throttle body and accelerator pedal assembly replaced. The problem is still not fixed. I lost power driving to work and heavy vibration and shaking. If I pull out in a turn and someone is coming up fast and this happens again it reduces my engine power and could cause a crash. Problem has been confirmed by a licensed mechanic, AutoZone, oreillys, and an independent mechanic. There was absolutely no warning this was gonna happen. It happened and I’ve spent $3,000 on replacement and labor costs trying to figure this out.

Engine power reduced warning keeps coming on. As well as stabilitrak and traction control turns off. Code p2138 pops up. I’ve spent over $1,000 trying to get this fixed because it is unsafe to drive it like that. It will be fixed for 1 or 2 weeks and then it’s time to take it to the shop again. So many people have this issue.

This system was sold as a MAIN SAFETY and SECURITY system, integrated in millions of General Motor products was advertised as next generation Safety. This system allowed active subscribers the peace of mind that in the event of an emergency, they had us covered. motor vehicle collision detection for the event that you crashed, they could send first responders. If the vehicle was stolen, they had safe methods to locate and disable the vehicle. If you locked your keys in the vehicle with your child or pet, they could unlock it for you.

OIL PRESSURE WARNING INDICATOR ALARMED, STATING SHUT ENGINE OFF IMMEDIATELY! WENT REPAIR SHOP CLOSE TO HOME, A DIAGNOSING TEST SHOWED NO CODES AT ALL. A CHECK OF BULLETINS FOR POSSIBLE ISSUE WITH CODES THAT SHOULD BE PRESENT, WERE NOT THERE? SHOP HAS RECOMMENDED I TAKE VEHICLE TO A DEALERSHIP FOR FURTHER ANALYSIS.

HEADLAMP MELTING PIGTAIL HARNESS

CHEVROLET USED EXTREMELY THIN WIRES AND THE WIRING HARNESS THAT GOES THROUGH THE DOOR HING BREAK APART INSIDE THE INSULATOR CAUSING THE AIRBAG SENSOR IN THE DRIVER DOOR NOT TO WORK. OTHER PEOPLE WITH SAME TRUCK HAVE HAD SAME ISSUE. IT IS A VERY DANGUROUS ISSUE AND A VERY EXPENSIVE ISSUE TO HAVE FIXED. THIS SHOULD NOT BE HAPPENING WIRE YOU NOT BREAK INSIDE THE INSULATOR.

TAKA RECALL IGNITION IS HARD TO TURN AND START

TL* THE CONTACT OWNS A 2012 CHEVROLET SILVERADO 1500. THE CONTACT STATED THAT THE VEHICLE EXPERIENCED A LOSS OF ENGINE POWER AND THE SERVICE TRACTION CONTROL, STABILITRAK, AND ENGINE POWER REDUCED WARNING INDICATORS ILLUMINATED. THE VEHICLE WAS TAKEN TO FREELAND CHEVROLET (LOCATED AT 5333 HICKORY HOLLOW PKWY, ANTIOCH, TN) WHERE IT WAS DIAGNOSED THAT THE VEHICLE NEEDED A NEW BATTERY. THE VEHICLE WAS REPAIRED, BUT THE FAILURE RECURRED. THE VEHICLE WAS RETURNED TO THE DEALER WHERE IT WAS DIAGNOSED THAT THE ACCELERATOR PEDAL POSITION SENSOR WAS DEFECTIVE AND NEEDED TO BE REPLACED; HOWEVER, THE FAILURE RECURRED. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHERE IT WAS DIAGNOSED THAT THE POWER TRAIN CONTROL MODULE WAS DEFECTIVE AND NEEDED TO BE REPLACED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURES. THE FAILURE MILEAGE WAS 35,056. *TT CONSUMER STATED POWER TRAIN CONTROL MODULE WAS DEFECTIVE. *JB

RIGHT HEADLIGHT IS IN-OPERABLE. LIGHT BULB HAS BEEN REPLACED WITH OE BULB, LIGHT STILL DOES NOT WORK. DEALER STATED THIS IS AN ONGOING ISSUE WITH THIS MAKE AND MODEL. DEALER ALSO STATED I WOULD NEED MULTIPLE HOURS OF DIAGNOSTIC TO DETERMINE THE ISSUE. NO ACCIDENTS, NO COLLISIONS. VEHICLE AT THIS TIME IS UNSAFE TO DRIVE AT NIGHT. MULTIPLE DEALERS IN MY AREA HAVE NOTED THIS AS AN ISSUE FOR MY MAKE AND MODEL. RIGHT LOW BEAM IS COMPLETELY IN-OPERABLE.

REVIEWED RECALL 18V295 AND MY VEHICLE HAS 1 BAD POWER WINDOW SWITCH WHICH DOES NOT WORK. COULD LIQUID HAVE CAUSED THIS SAME PROBLEM UNDER THIS RECALL? DOES NOT WORK IN ANY VEHICLE MOTION.

IGNITION SWITCH IS BAD. IT LOCKS UP TO WHERE THE KEY WILL NEED TO BE TURNED AROUND AND TRIED AGAIN. WHEN TAKING KEY OUT THE KEY HOLE (AT TIMES) STAYS IN THE ON POSITION AND DINGS AS I LEAVE MAKING THE ASSESSORIES FUNCTION STAY ON. IF KEY IS BUMPED THE KEY CAN TURN OFF TRUCK MAKING ALL POWER TURN OFF.

DRIVER'S SIDE LOW BEAM HEADLIGHT GOES OUT. THE LIGHTBULB IS IN GOOD ORDER. THE PIGTAIL SHOWS SIGNS OF EXCESSIVE HEAT/SMALL FIRE, PLASTIC MELTING, CARBON IN THE METAL CONTACT ON THE LIGHTBULB AND SOCKET. THE PIGTAIL WAS REPLACED AND LASTED APPROXIMATELY ONE MONTH TO SHOW THE SAME ISSUES. I AM AFRAID OF A VEHICLE FIRE. THE VEHICLE'S STABILITRACK IS UNUSABLE, THE WARNING LIGHT IS ON. THE ISSUES HAPPEN WHILE THE VEHICLE IS IN MOTION AND STATIONARY. THE ISSUES HAPPENED SUDDENLY DURING NORMAL CITY/HIGHWAY DRIVING. THE ISSUES ARE ONGOING AND STARTED SIX MONTHS AGO.

LIGHTS GO DIM ON IT ALL THE TIME AND THE ELECTRIC SYSTEM IN IT IS BAD SOMETIMES THE AIR CONDITION WORKS MOST OF THE TIME IT DON'T AND THE CRUISE QUIT WORKING IN IT

MY TRUCK SHOULD HAVE NO ISSUES AS I FOLLOW THE MAINTENANCE SCHEDULE AND TAKE GOOD CARE OF MY VEHICLE BUT IT HAS HAPPENED TWICE WHERE I WAS IN THE MIDDLE OF THE INTERSTATE WHEN MY VEHICLE DISPLAYED THE CHECK ENGINE LIGHT, TRACTION OFF, STABILTRAC OFF, THE AIRVENTS STOPPED BLOWING COOL AIR AND RELEASED HUMIDITY, BRAKES WERE NOT FUNCTIONING PROPERLY (HARD TO ACTUALLY BREAK), STEERING WHEEL/POWER STEERING WAS MALFUNCTIONING MAKING IT ALMOST IMPOSSIBLE TO TURN OR GET OUT OF TRAFFIC AND IT SEEMS THE VEHICLE JUST DECIDED TO SUDDENLY STALL WHILE IN MOTION. I WAS VERY LUCKY DUE TO SUDDEN HIGH RISK OF A VEHICLE CRASH AND WAS ABLE TO PULL OVER WITHOUT GETTING ANYONE HURT. I TURNED THE VEHICLE OFF ONCE I GOT IN PARK AND LOOKED UNDER THE HOOD, EVERYTHING WAS FINE SHOWING NO ISSUES BUT I WENT TO START THE VEHICLE AND IT DID NOT CRANK OR TRY...

I NOTICED YESTERDAY THAT THE SERVICE AIR BAG WARNING CAME ON. DIDN'T THINK ANYTHING OF IT. GOT IN THERE THIS MORNING 7/15 AND WAS DRIVING DOWN THE ROAD AND IT DID IT AGAIN. THIS TIME ALL OF THE ELECTRICAL WENT OUT FOR A MINUTE INCLUDING THE SPEEDOMETER. COULDNT EVEN TURN MY AC ON OR OFF. CALLED THE DEALERSHIP WE GOT IT FROM AND THEY TOLD ME I WAS LOOKING AT A 2 WEEK WAIT BUT I COULD DROP IT OFF ON 7/18 AND THEY WOULD GET TO IT.
