2007 Chevrolet Silverado engine problems

ENGINE

ON MY 2007 SILVERADO I AM CONSTANTLY HAVING TO TAKE IT IN TO GET SERVICED FOR TRACTION CONTROL AND SERVICE STABILITRAK. MY ACTIVE FUEL MANAGEMENT LIFTERS ARE ALSO NOT FUNCTIONING PROPERLY. THIS HAPPENS WHEN I AM MAKING TURNS. THE VEHICLE WILL LOSE CONTROL AND IT FEELS VERY DANGEROUS.MY BRAKES ARE CONSTANTLY BEING REPLACED AND I FEEL LIKE THERE IS SOME MAJOR ISSUES WHEN THE VEHICLE WAS BUILT.

WHILE MERGING ONTO THE EXPRESS WAY I HAD A MAJOR LOSS OF POWER AND A SLIGHT SHAKE IN MY SILVERADO. MULTIPLE ENGINE LIGHTS CAME ON (STABILITY TRACK, TRACTION CONTROL, AND BLINKING ENGINE LIGHT). ON MY WAY TO THE NEAREST GM DEALER, AT EVERY STOP LIGHT THE TRUCK LACKED POWER TO GET GOING WHEN THE PEDDLE WAS PUSHED, THEN IT WOULD KICK IN AND SCREECH THE TIRES. AFTER LEAVING THE TRUCK AT THE DEALER, I RECEIVE PHONE CALL FROM THE DEALER THE FOLLOWING DAY STATING THAT THE LIFTER (AFM LIFTER) HAD MALFUNCTIONED AND WAS STUCK. I ASKED WHAT CAUSES THIS (BECAUSE MY TRUCK ONLY HAS ABOUT 39,700 MILES ON IT), AND THE DEALER STATED IT WAS "AN ISSUE WITH THE DESIGN OF THE ENGINE." I THEN RESEARCHED THE INTERNET (GM FORUMS, SOCIAL MEDIA, NHTSA) TO FIND OUT THAT THIS IS A HUGE ISSUE. MANY OWNERS HAD THE BAD LIFTER REPLACED UNDER WARRANTY, ONLY TO HAVE A DIFFERENT LIFTER GO BAD. I DECIDED TO HAVE THE DEALER REPLACE ALL MY LIFTERS, BECAUSE THAT IS WHAT THEY RECOMMENDED AND THEY ADMITTED THERE IS A GOOD CHANCE I WOULD BE BACK IN FOR THE SAME ISSUE ON THE OTHER LIFTERS IF I DIDN'T REPLACE THEM. THE DEALER CONTACTED GM TO SEE IF ANY OF MY REPAIR COULD BE COVERED UNDER THE POWERTRAIN WARRANTY BECAUSE I ONLY HAVE 39,700 MILES ON IT, BUT MY TRUCK WAS 8 YEARS OLD SO THEY SAID THEY WOULDN'T. I CONTACT GM TO SEE IF I COULD DIRECTLY GET ANYTHING COVERED SEEING I ONLY HAD 39,700 MILES, PLUS BOUGHT AN EXTENDED WARRANTY THAT JUST EXPIRED LAST YEAR. I WAS TRANSFERRED THROUGH 5 DIFFERENT REPRESENTATIVES THAT ALL ADMITTED THAT THE LIFTER FAILURE IS "AN ISSUE, BUT NOT A RECALL." IF THEY KNOW ITS AN ISSUE, THE DEALERS KNOW ITS AN ISSUE, ITS A EXTREMELY COMMON ISSUE ALL ACROSS THE INTERNET, WHY WONT GM TAKE CARE OF IT? MY SILVERADO COST OVER $45,000 WHEN NEW, YOU THINK IT SHOULD LAST WELL OVER 100,000 MILES WITH NO ENGINE PROBLEMS.

DEFECTIVE EXHAUST MANIFOLD BOLTS. THE BOLT HEADS ARE BREAKING OFF OF MY 2007 CHEVY SILVERADO CREW CAB TRUCK. THIS IS A WELL MAINTAINED LIGHTLY USED TRUCK I USE FOR WORK. AFTER DISCOVERING THE PROBLEM, I WENT TO THE INTERNET TO SEARCH SOLUTIONS ON THIS PROBLEM AND THAT'S HOW I FOUND OUT THAT THIS IS A VERY BIG PROBLEM WITH THIS TRUCK ENGINE. THERE IS NO TSB ON THIS OR A RECALL, BUT THERE SHOULD BE, ENGINES AFFECTED ARE ALL V-8'S FROM 4.8L, 5.3L, AND 6.0L. VERY EXPENSIVE REPAIR THAT SHOULDN'T HAVE HAPPENED IN THE FIRST PLACE.

ENGINE AND ENGINE COOLING

UPON DRIVING THE ENGINE BEGAN MAKING EXTREME NOISE AND MAJOR LOSS OF POWER. MULTIPLE ENGINE LIGHTS CAME ON AND BACKFIRE THROUGH EXHAUST. CONTACTED CHEVY DEALER AND DROPPED OFF FOR DIAGNOSIS. PROBLEM WAS ACTIVE FUEL MANAGEMENT LIFTER FAILURE. (PLEASE TAKE NOTE THAT THIS ISSUE IS ALL OVER THE INTERNET AND SOCIAL MEDIA) THIS PROBLEM IS HAPPENING TO A HIGH VOLUME OF SILVERADO TRUCK MANUFACTURED AFTER 2007 WITH AFM. CHEVROLET HAS BULLETINS ON THE ISSUE BUT WILL NOT RECALL TO REPLACE ALL AFM LIFTERS. THEY ONLY REPLACE THE LIFTERS THAT FAIL. THIS CAUSES ISSUES LATER WHEN ADDITIONAL LIFTERS FAIL. IF ALL AAFM LIFTERS (8) WOULD BE REPLACED AT THE SAME TIME CONSUMERS WOULDN'T BE COMPLAINING VIA SOCIAL MEDIA AND INTERNET. CHEVROLET ACKNOWLEDGES THE PROBLEM BUT REFUSES TO RECALL. REASON FOR REFUSAL IS IT SEEMS TO HAPPEN AROUND 50,000 MILES AND ABOVE AND AFTER THE REPAIR THEY HOPE THAT THE ISSUE HAPPENS AFTER THE 100,000 MILE WARRANTY WHEN REPAIRS ARE PAID FOR BY CONSUMERS COSTING THOUSANDS OF DOLLARS. I PERSONALLY HAVE READ OF THIS HAPPENING AND HAD IT HAPPEN JUST RECENTLY. GM REFUSES TO BACK THEIR PRODUCT ALTHOUGH THEY RECOGNIZE THE PROBLEM. BULLETINS HAVE BEEN ISSUED BUT I WAS TOLD THAT THE NHTSA MAKES THE CALL AFTER ENOUGH COMPLAINTS ARE FILED BY CONSUMERS. PEOPLE JUST DON'T KNOW THIS AND I AM REQUESTING YOU URGENTLY LOOK INTO THIS ISSUE. CATASTROPHIC ENGINE FAILURE CAN RESULT COSTING CONSUMERS A LOT OF MONEY. WE ARE JUST THE LITTLE GUY UP AGAINST A LARGE AUTOMOBILE MANUFACTURER. WE NEED YOUR ASSISTANCE IN FORCING GM TO ISSUE A RECALL ON THESE VEHICLES WITH THE ACTIVE FUEL MANAGEMENT. OUR HANDS ARE TIED BECAUSE OF THIS. WE REQUEST THAT IF THERE IS A AFM LIFTER FAILURE THAT ALL LIFTERS BE REPLACED INSTEAD OF THE ONES THAT FAILED. THIS IS ONLY LOGICAL ESPECIALLY WHEN GM KNOWS THERE IS A PROBLEM. PLEASE HELP US THE CONSUMER.

AFTER BUYING MY TRUCK I NOTICED A "TICK" NOISE FROM THE EXHAUST ON MY TRUCK. AFTER TAKING MY TRUCK TO THE SHOP I WAS TOLD THAT MY EXHAUST BOLTS INTO THE ENGINE WERE BROKEN. THIS IN HAND MADE ME FAIL THE EMISSION TEST AND COSTING ME ALOT OF MONEY. AFTER RESEARCH IT IS STATED IN MANY PLACES THAT THIS IS A COMMON OCCURRENCE WITH THESE CHEVY MODELS, AND CHEVY REFUSES TO DO ANYTHING ABOUT POLLUTING THE ENVIRONMENT AND COSTING IT OWNERS MONEY IN THING THAT SHOULD NOT BREAK EVER.

ENGINE AND ENGINE COOLING

I TOOK MY NEW CHEVY TRUCK INTO THE DEALER FOR SOME NEW FACTORY EQUIPMENT (BUG DEFLECTOR AND BED LINER) TO BE INSTALLED BY THEM. WHILE THE DEALER HAD MY 2007 CHEVY TRUCK THEY LOADED 2008 POWER TRAIN SOFTWARE INTO IT'S COMPUTER WITHOUT MY PERMISSION. THE 2008 SOFTWARE CHANGED THE WAY MY TRUCK RUNS. THE POWER TRAIN NOW HAS A SPEED LIMITER ON IT AND THE STABILITY CONTROL WAS CHANGED. IT WILL NOT GO AS FAST IT AS USE TO GO BEFORE THE CHANGE. I WAS TOLD BY THE DEALER AND GM THEY WOULD NOT PUT MY TRUCK BACK THE WAY IT WAS AS WHEN I BOUGHT IT. THEY TOLD ME THAT THE REASON WAS THE GOODYEAR TIRES AND THE TRUCK DESIGN WERE UNSAFE WITHOUT THE 2008 SOFTWARE INSTALLED AND WOULD NOT CHANGE MY TRUCK BACK TO THE 2007 CONFIGRATION . I HAVE NOT GOTTEN ANY RECALL OR SAFETY NOTICES ABOUT THIS ISSUE. I THINK GM AND THE DEALER MADE A MISTAKE AND DO NOT WANT TO CORRECT IT. IF THERE IS A PROBLEM WITH THE TIRES (GOODYEAR WRANGLER TIRES) AND THE 2007 TRUCK DESIGN (GM SILVERADO 1500 LTS CREW CAB) GM IS TRYING TO COVER IT UP. THERE ARE HUNDREDS OF THOUSANDS OF 2007 GM TRUCKS, CARS, SUV'S EVEN CADILLAC'S THAT HAVE THE SAME POWER TRAIN IN THEM THAT MY TRUCK HAS AND THEY ARE NOT CHANGING THE COMPUTER PROGRAMS IN ALL THOSE VEHICLES. I WAS TOLD THEY WOULD BE CHANGED ONLY IF THE TRUCKS, SUV'S AND CARS WERE BROUGHT IN FOR ANY KIND OF SERVICE WORK, BUT WOULD NOT BE CHANGED IF NOT SERVICED BY GM. SENSE THERE HAVE BEEN NO RECALL NOTICES ABOUT THESE ISSUES I THINK GM IS TRYING TO COVER SOMETHING UP . THE VERY LEAST TRYING TO COVER UP THEIR DEALERS AND THERE MISTAKE BY ALTERING MY TRUCK WITHOUT MY PERMISSION OR THEY DO HAVE A SERIOUS PROBLEM THAT THE PUBLIC SHOULD BE AWARE OF. PLEASE LOOK INTO THIS. THE SAME TIRES ARE ON FORDS AND DODGES AND THEY DON'T SOFTWARE LIMIT THERE PERFORMANCE. I PAID TOP DOLLAR FOR GM'S BEST TRUCK WITH THE BIGGEST ENGINE MADE FOR IT, I COULD HAVE SAVED A LOT OF MONEY BY BUYING A SIX CYLINDER ENGINE INSTEAD OF THE BIG V-8. IF I KNEW GM WAS GOING TO DE-RATE MINE.
