2010 CHEVROLET AVALANCHE Power Train Problems

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...

MY TRANSMISSION WHEN TAKING OFF FAST SOUND LIKE IT'S IN NEUTRAL AND THEN WHEN I LET OFF THE FAST IT GOES IN GEAR. ALSO MY DASH BOARD IS CRACKING AND FOUND BE A SERIOUS AIRBAG ISSUE. I'VE SEEN HUNDREDS OF COMPLAINTS ABOUT THIS AND A RECALL HASN'T BEEN ISSUED. THE RECALL NEEDS TO BE ISSUED SO I COULD BE FIXED ASAP. THIS IS A SERIOUS HAZARD.!!!

WHEN TURNING THE REAR DIFFERENTIAL MOMENTARILY LOCKS UP SOUNDING LIKE LITTLE SKIDS. DURING NORMAL SLOW ACCELERATIONS THE ISSUE CAUSES THE TRUCK TO LUNGE OR BUMP FEELING LIKE IT IS COMING FROM THE DIFFERENTIAL. SINCE I FISRT PURCHASED THE THRUCK NEW FROM THE DEALER THERE HAS ALWAYS BEEN AN ISSUE WITH CLUNKING FROM THE DRIVETRAIN. DEAL SAID THEY COULD FIND IDENTIFY ANYTHING.
