The contact owns a 2012 Chevrolet Avalanche.

MY 2012 CHEVROLET AVALANCHE 5.3L ENGINE HAS STARTED A OIL CONSUMPTION LOSS. THERE WAS A SERVICE BULLETIN ISSUED OCT. 30TH 2013 TO CORRECT THIS PROBLEM. IT DOES NOT FIX THE PROBLEM! WHAT I'VE READ IS THAT WHERE THE CYLINDERS DEACTIVATE TO HELP FUEL ECONOMY AFTER TIME THOSE PISTONS GET DAMAGED FROM NOT HAVING FUEL OR FIRE ON THEM AND ITDAMAGES PISTONS AND CAUSES OIL CONSUMPTION. IN THE PAST FEW DAYS I HAVE FOUND OUT THAT THERE ARE 5 PEOPLE I KNOW WITH THE SAME ISSUE. LOOKING ON LINE THERE APPEARS TO BE CLASS ACTION LAW SUITS ALL ACROSS THE COUNTRY ON THIS ISSUE. GM/CHEVROLET KNOW THEY HAVE A PROBLEM BUT REFUSE TO TAKE CARE OF THIS PROBLEM. THERE IS NO RECALL ON THIS AND I'M SURE NEVER WILL BE BECAUSE IT HAPPENS WHEN THE ENGINES REACH HIGHER MILEAGE. I HAVE ALL MY MAINTENANCE RECORDS ON MY TRUCK AND HAD NO INTENTION OF TRADING IT, BUT NOW THE MOTOR WILL HAVE TO BE REBUILT OR REPLACE.

WHEN NEARING A STOP LIGHT AT EST. 15 MPH I STEPPED ON THE BRAKE AND IT WAS LIKE STEPPING ON A ROCK. THE PEDAL DID NOT MOVE. I POUNDED ON THE PEDAL AND FINALLY HAD ENOUGH BRAKE TO STOP. THERE WERE NO WARNING LIGHTS. AFTERWARDS THE BRAKES WERE GOOD. THIS WAS REPEATED TWICE MORE. I TOOK IT TO A BRAKE SHOP WHERE THEY CHECKED ALL MECHANICAL FUNCTION AND FOUND NOTHING WRONG. THEY HOOKED UP THE COMPUTER AND FOUND NO CODES. I TOOK IT TO A CHEVROLET DEALER AND THEY COULD NOT FIND ANY CODES. DURING A TEST DRIVE THE MECHANIC UNHOOKED THE VACUUM LINE AND HAD NO VACUUM. HE FOUND THE MOTOR WAS MAKING VACUUM. BACK AT THE SHOP HE SAID IT WAS PROBABLY THE VACUUM BOOSTER. WHEN IT WAS REPLACED THE BRAKES WORKED AS THEY ALWAYS HAD EXCEPT WHEN THEY DIDN'T WORK. NOW THAT THE BOOSTER HAS BEEN REPLACED I DO NOT KNOW IF THE PROBLEM IS FIXED SINCE IT IS A RANDOM PROBLEM. I WILL NOT BE ABLE TO TRUST THE BRAKES UNTIL AT LEAST A MONTH GOES BY WITH NO PROBLEMS. THE TRUCK HAS LESS THAN 29000 MILES ON IT.

Exterior lighting
Reports naming headlights, tail lights, turn signals and other exterior lighting.
From owner reports, verbatim
I HAVE BEEN TOLD THAT ONE OF MY DAYTIME RUNNING LIGHTS IS BURNED OUT. I HAVE BEEN UNABLE TO INSPECT THE LIGHTS BECAUSE THEY ONLY COME ON IF THE TRANSMISSION IS NOT IN PARK. I CALLED DEALER TO FIND OUT IF THERE IS ANY WAY TO HAVE THEM COME ON WITHOUT THE TRANSMISSION IN GEAR. THE DEALER SAID TO SET THE PARKING BRAKE, PUT THE TRANSMISSION IN GEAR, AND GET OUT TO LOOK AT THE LIGHTS (OR HAVE A SECOND PERSON LOOK AT THEM, WHICH IS NOT PRACTICAL FOR ME). THIS SOUNDS LIKE A DANGEROUS PRACTICE. THERE SHOULD BE A BETTER WAY TO DO THIS. MY OLD 2007 AVALANCHE WOULD HAVE THE DAYTIME RUNNING LAMPS ON WHEN IN PARK.
