2016 CHEVROLET SILVERADO 1500 Complaints

AT SPEED ABOVE 50 MILES AN HOUR THERE IS VIBRATION IN THE VEHICLE AND IT GET WORE THE FASTER YOU GO AND AT 80 MILES AN HOUR THERE IS A ROAR AND THE WHOLE VEHICLE IS VIBRATING BADLY AND I AM AFRAID TO DRIVE THE VEHICLE. THIS IS A BIG PROBLEM AND CHEVROLET HAS HAD MY TRUCK FOR 5 WORK DAYS AND HAS YET TO FIGURE OUT WHAT IT WRONG.

THE TRUCK IS LESS THAN 3 YRS OLD WITH ONLY 23671 MILES. CHECK ENGINE LIGHT CAME ON. P050D CODE AND THE TRANSMISSION BEGAN TO DOWN SHIFT HARD AT TIMES WHEN SLOWING DOWN. DEALER SAID THERE WAS CARBON BUILD UP ON CYLINDER 1 VALVES THAT CAUSED THEM TO STICK AND A MISFIRE. I FOUND IT INTERESTING THAT CYLINDERS 1-4-6-7 ARE THE CYLINDERS THAT SHUT DOWN FOR AFM ACTIVE FUEL MANAGEMENT SYSTEM WHEN IT GOES INTO V4 MODE. DEALER SAID IT WAS NOT RELATED. SAID IT WAS POOR FUEL. SAID I NEED TO RUN TOP TIER DETERGENT FROM SELECT GAS STATIONS. THAT IS THE FIRST TIME ANYONE HAS TOLD ME THIS. THAT'S NOT IN THE OWNERS MANUAL AND NO ONE TOLD ME I WOULD NEED TO USE SPECIAL GAS STATIONS WHEN I BOUGHT THE TRUCK BRAND NEW. I THEN TOLD HIM THE TWO STATIONS I USE ARE MOBIL AND SUNOCO. BOTH OF WHICH ARE ON THE TOP TIER FUEL DISTRIBUTOR LIST. INTERESTING FACT: TOP TIER FUELS IS A REGISTERED TRADEMARK OF GENERAL MOTORS. THEY FAILED TO MENTION THAT WHEN THEY TOLD ME ABOUT MY "POOR FUEL" WHICH IS APPARENTLY A LICENSED GM PRODUCT. I WAS TOLD IF THIS HAPPENS AGAIN I WOULD HAVE TO PAY AS IT WOULD LIKELY BE OUTSIDE THE BUMPER TO BUMPER WARRANTY PERIOD (36 MOS). APPARENTLY THE FUEL SYSTEM IS NOT PART OF THE POWER TRAIN? FOUND NOTHING WITH THE TRANSMISSION. NOT SURPRISED. LAST NEW CHEVROLET I WILL EVER BUY.

AIR CONDITIONING COMPRESSOR HAD CRACKED. THIS IS A KNOWN PROBLEM ON THESE VEHICLES AND GM DOES NOTHING ABOUT IT. IM SURE THERE ARE THOUSANDS OF COMPLAINTS. TRUCK IS 3 YEARS OLD WITH 50K MILES. FAIR TO HAVE TO PAY A $1,000+ FOR GMS NEGLECT? PLEASE STEP IN HERE, A LOT OF PEOPLE ARE GETTING HURT BY THIS. NO RECALL HAS BEEN ISSUED AND CLEARLY IT WARRANTS ONE. THANK YOU FOR YOUR TIME.

BRAKES BARELY WORK AT LOW SPEED AND REQUIRE A LOT OF PRESSURE TO GET THE VEHICLE TO STOP. NEARLY BACKED MY TRUCK INTO A LAKE WHILE BACKING DOWN A BOAT LAUNCH. VERY DANGEROUS! THERE ARE SO MAY COMPLAINTS ON THIS ISSUE AND THE NHTSA HAS BEEN "INVESTIGATING" IT FOR OVER 6 MONTHS NOW. WHEN WILL SOMETHING BE DONE?

UNRESPONSIVE BRAKES AT LOW SPEED. VERY DANGEROUS AND NOT SURE WHY THIS ISNT A RECALL. HOW MANY PEOPLE HAVE TO GET INJURED OR DIE BEFORE ITS FIXED?

THE BRAKES WENT STIFF AND MY WIFE WAS BARELY ABLE TO GET THE TRUCK TO STOP. THIS WAS LUCKILY JUST BACKING OUT OF OUR DRIVE WAY. IT COULD HAVE BEEN REALLY BAD IF SHE WAS GOING FASTER OR NEEDED TO STOP QUICK.

WHEN APPLIED BRAKE PEDAL WAS VERY DIFFICULT TO PUSH DOWN AND BRAKES DID NOT FUNCTION PROPERLY. VEHICLE WAS IN MOTION ON A CITY STREET AT TIME OF INCIDENT. TOOK TO CHEVROLET DEALERSHIP AND THEY TOLD ME IT WAS A BAD BRAKE BOOSTER AND THAT THEY HAVE HAD A LOT OF TROUBLE WITH THEM.

ON THE DATE CITED, I WAS BACKING UP A TRAILER DOWN A HILL SLOWLY. HAD RELEASED THE BRAKES THEN REAPPLIED AND SUDDENLY THE BRAKE PEDAL WAS STIFF AND IT WAS VERY HARD TO STOP. MANUALLY APPLIED FULL STRENGTH TRAILER BRAKES AND THE TRAILER HELPED STOP THE TRUCK. 3 DAYS LATER (5/30/19) I EXPERIENCED A SIMILAR INCIDENT. I WAS PARKED, PUT THE TRUCK IN DRIVE ACCIDENTALLY AND TOOK MY FOOT OFF THE BRAKE. WHEN I APPLIED THE BRAKE AGAIN QUICKLY TO SWITCH TO REVERSE, THE PEDAL WAS EXTREMELY STIFF. NEARLY HIT THE VEHICLE IN FRONT OF ME. PUT INTO REVERSE AND NO ISSUE. AT NO POINT WAS A "SERVICE BRAKE ASSIST" MESSAGE DISPLAYED AS NOTED IN A 'SPECIAL WARRANTY' LETTER RECEIVED FROM GM IN THE MAIL BETWEEN THE INCIDENTS. NO OTHER ERROR CODES OR MESSAGES WERE DISPLAYED. 2 YEARS AGO AFTER HAVING TOWED A TRAILER, THE MESSAGE "SERVICE BRAKE ASSIST" WAS DISPLAYED ON THE SCREEN ONCE, THE LOCAL SERVICE DEALER PULLED CODES AND DID NOT PERFORM ANY REPAIR.

APRIL 2019 LETTER FROM GM SAYING MY BRAKES COULD POSSIBLY LOOSE THEIR VACUUM ASSIST. THEY DO NOT WANT TO FIX THE PROBLEM UNLESS I HAVE PROBLEMS AND EXTENDED THE WARRANTY TO 6 YEARS AND 72,000. WHAT A COP OUT, WHAT IF MY BRAKES DO NOT WORK PROPERLY IN A TIGHT STOPPING SITUATION? I HAVE ATTACHED A COPY OF THE LETTER, PLEASE DO NOT LET GM PLAY WITH OUR SAFETY ON A $52,000 VEHICLE OR ANY VEHICLE.

VACUUM PUMP FAILED SUDDENLY, ALMOST HAD A COLLISION DUE TO VERY HARD BRAKING. THE VEHICLE IS CURRENTLY AT THE DEALER FOR REPAIRS ($2,100 INCLUDING NEW BRAKES). I DON'T HAVE ANY DOCUMENTATION YET.
