In October of 2020, my avalanche only would start in winter after disconnecting and reconnecting the battery. It was also on numerous occasions go into limp mode while driving at normal city speeds meaning it wouldn’t go above 25 miles an hour. The entire dash would light up. It threw numerous codes. Had to be towed to get it looked at but then would mysteriously start without issue. I took it to young Buick gmc in Layton Utah with no resolution. Finally in December 2020 it was determined by now Heritage Chevrolet in Evanston Wyoming to be the Onstar module. This part was no longer available and couldn’t be replaced. The dealership’s solution was to wire around the faulty part which has allowed the truck to start and no longer go into limp mode from 70mph on highway to 20mph without notice. I immediately got a hold of Chevrolet to get a satisfactory answer about why I couldn’t get the part that was making the vehicle unsafe to drive. They said the part was no longer being manufactured and it wasn’t their problem sorry about the inconvenience Case number [XXX]. I did have the dealership wire around it so I have the truck working, but Chevrolet did not care about the truck going into limp mode suddenly on the highway and it could have caused an accident. They not not offer any compensation for the part not being manufactured and according to to your website if a part is causing a safety issue they are they are required to have that part fixed. I am still upset about their lack of support and service and want Chevrolet held accountable. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I AM VERY DISASIFIED WITH THE WAY THE ISSUE HAS BEEN HANDLED. I DRIVE A 2010 CHEVROLET AVALANCHE LTZ WITH 111,000 MILES ON IT. I PURCHASED THIS VEHICLE IN 2005 WITH 38,000 MILES. A YEAR LATER DURING THE SUMMER TIME I BEGAN TO HAVE ELECTRICAL ISSUES (WHILE IN MOTION VEHICLE GUAGES START SPAZZING OUT GOING UP AND DOWN, RADIO CUTS IN AND OUT, DOOR LOCKS CYCLE UP AND DOWN AND VEHICLE STALLS, DOESNT SEEM TO ACCELERATE AND SHIFT INTO SECOND GEAR. I HAVE BEEN STRANDED IN THE MIDDLE LANE OF THE FREEWAY TRAVELING 60 MILES PER HOUR WHEN SUDDENLY IT BEGINS TO ACT UP. THIS IS A MAJOR SAFETY ISSUE WITH THREE CHILDREN IN THE VEHICLE AND MULTIPLE CARS DRIVING AT THE SAME SPEED AS I TRY TO GET OVER TO THE SHOULDER TO SHUT OFF MY VEHICLE BUT SEEMS STUCK IN NEUTRAL PREVENTING ME FROM QUICKLY GETTING OFF THE FREE WAY. AT TIMES I WILL CYCLE THE IGNITION KEY OFF AND ALL POWER CUTS OUT. I HEAR A CLICKING NOISE AND LIGHTS FLICKER BACK ON, WHICH IS MY CUE TO CYCLE THE IGNITION KEY BACK ON. SOMETIMES IT WORKS AND OTHERS IT DOESN'T. AT TIME POWER DOESN'T COME BACK FOR AT LEAST 5 MINUTES. THIS OCCURS SPORADICALLY DURING THE SPRING AND SUMMER TIMES. I HAVE TAKEN IT TO THE DEALERSHIP WHERE THEY WERE UNABLE TO DIAGNOSE THE PROBLEM, STATING THEY COULDNT DUPLICATE THE PROBLEM. THEY ASSUMED THE IGNITION SWITCH SO THAT WAS CHANGED BUT PROBLEM CONTINUED. I CONTACTED CHEVROLET WHERE THEY OPENED A CASE BUT IT TROUBLES ME THAT THEY WORK ON A CASE BY CASE AND STATED THEY ARENT AWARE OF MULTIPLE SIMILAR COMPLAINTS. VEHICLE WAS DROPPED OFF AGAIN WHERE THEY STILL COULDN'T DIAGNOSE THE PROBLEM BUT DID RESEARCH AND FOUND THE CABLE MAY POSSIBLY BE THE REASON SO THAT IS STILL PENDING. IF THIS IS SO COMMON AND A MAJOR SAFETY CONCERNS ON THE HIGHWAY WHY HASN'T THERE BEEN A RECALL FOR CHEVROLET. I HAVE ATTACHED A DOCUMENT SENT FROM THE DEALERSHIP ABOUT THE CABLES. CHEVY NEEDS TO DO SOMETHING ABOUT THE ELECTRICAL.

THUS FAR, NOTHING HAS "HAPPENED" WITH MY VEHICLE, BUT THERE HAS BEEN A RECALL IN EFFECT FOR THE AIRBAGS IN MY VEHICLE FOR WELL OVER A YEAR AND NOTHING HAS BEEN DONE TO REPLACE THE AIRBAGS. I AM ALSO HAVING SOME ELECTRICAL PROBLEMS WITH MY TRUCK NOT SHUTTING OFF WHEN I REMOVE THE KEY, AND THE INTERIOR DOME LIGHTS WILL NOT TURN ON WHEN THE BUTTON IS PRESSED (THIS HAS ALL BEGAN SINCE THE RECALL WAS INITIATED BUT NOT TAKEN CARE OF). I JUST WANT MY AIRBAGS REPLACED, AS THEY ARE SUPPOSED TO BE, GIVEN THE RECALL, AND IF THE RECALLED PARTS ARE RESPONSIBLE FOR THE ADDITIONAL PROBLEMS I AM NOW HAVING WITH MY TRUCK, I WANT THOSE ADDRESSED AND REPAIRED AS WELL. THE LENGTH OF TIME THIS HAS TAKEN TO ADDRESS IS BEYOND UNREASONABLE AND I HAVE BEEN AS PATIENT AS I CAN BE WAITING FOR THIS RECALLED PART TO BE REPLACED. *TR

I WAS ON VACATION AND HAD MY AVALANCHE RUNNING WHILE I PACKED IT UP TO RETURN HOME. AFTER ABOUT 5 MINUTES OF RUNNING IDLE, THE CHECK ENGINE LIGHT CAME ON AND THE DISPLAY SHOWED REDUCED ENGINE POWER, SERVICE TRACTION CONTROL, AND SERVICE STABILITRAK. THIS HAD HAPPENED TO THE TRUCK THREE TIMES BEFORE AND EACH TIME THEY REPLACED THE ACCELERATOR PEDAL POSITIONAL SENSOR. (I ALSO HAD A 2007 CHEVROLET TAHOE, AND AFTER HAVING IT REPAIRED SEVEN TIMES FOR FAILING SENSORS AND GOING INTO REDUCED ENGINE POWER WHILE ON THE HIGHWAY THREE TIMES WE WERE FORCED TO SELL IT). WE ARE VERY FAMILIAR WITH THIS ISSUE! HOWEVER, I WAS ABLE TO LOCATE A DEALERSHIP IN THE AREA AND THEY TESTED IT TO FIND THAT THE THROTTLE BODY WAS OUT, AND THEY REPLACED THE THROTTLE BODY AND THE ASSOCIATED SENSOR. I WAS RELIEVED TO HEAR THAT THIS WAS A DIFFERENT ISSUE THAN BEFORE AND THAT MY PROBLEMS WERE FIXED. THIS WAS NOT THE CASE. LAST WEEK, THE ENGINE POWER REDUCED AGAIN AND THE TRUCK IS NOW IN THE SHOP FOR THE FIFTH TIME. *TR

I WAS ABLE TO GET IT TO THE DEALERSHIP AND ARE WORKING ON IT NOW. THIS IF THE FIFTH TIME THIS HAS HAPPENED TO MY TRUCK. MY WIFE AND I JUST SOLD OUR 2007 CHEVROLET TAHOE AND THE ONLY REASON WAS THE ENGINE POWER REDUCED ERROR OCCURRED ON IT SEVEN TIMES, THREE IN MONTH PRIOR TO SELLING IT. THIS IS A MAJOR PROBLEM AND COULD HAVE EASILY RESULTED IN A SEVERE ACCIDENT. BOTH CARS WERE ONLY EVER SERVICED AT CHEVROLET DEALERSHIPS AND EACH TIME, THEY INSISTED IT WAS FIXED AND THE PROBLEM WAS GONE. WE HAVE NO FAITH IN CHEVROLET AT THIS TIME! *TR
