I BOUGHT MY 2012 CHEVY OCTOF 2013. NOW AFTER 11000 MILES MY FRAME LOOKS LIKE A TRUCK OUT OF THE 80'S. I TOOK IT BACK TO THE LOCAL DEALER. THERE FIX IS TO SCRAPE OFF THE RUST AND PUT THE SAME CRAP BACK ON THE FRAME. SO I KNOW THAT THIS ISSUE WILL ONLY LAST A VERY SHORT TIME. *TR

TL* THE CONTACT OWNS A 2012 CHEVROLET SILVERADO. THE CONTACT STATED THAT WHILE THE VEHICLE WAS PARKED WITH THE EMERGENCY BRAKE ENGAGED, THE CONTACT REACHED IN FROM THE PASSENGER'S SIDE TO SHUT THE ENGINE DOWN AND THE VEHICLE ROLLED AWAY IN REVERSE. THE CONTACT WAS DRAGGED SEVERAL FEET BEFORE THE VEHICLE CRASHED INTO A BRIDGE. THE CONTACT SUSTAINED MAJOR BRUISING AND SCRATCHES TO SEVERAL PARTS OF THE BODY. A POLICE REPORT WAS NOT FILED.

EFM ISSUE: LIFE-TIME CHEVY SILVERADO OWNER, CURRENTLY OWN 2003 & 2012 1500 SILVERADO 1/2 TONS. EVER SINCE GM STARTED USING EFM CHIPS, FOR SOME UNKNOWN REASON THE ENGINE WILL LOSE SEVERAL QUARTS OF OIL FOR NO REASON. WITHOUT WARNING THE CHECK ENGINE LIGHT COMES ON. PULL-OVER & CHECK THE OIL LEVEL. ON EVERY OCCASION, (SEVERAL INCIDENTS NOW), MUCH TO MY SURPRISE THE OIL LEVEL BARELY REGISTERS ON THE DIP STICK. WHERE DID 3-4 QUARTS OF OIL GO? YESTERDAY THE OIL LEVEL WAS FULL, TODAY THE OIL LEVEL IS ALMOST NON-EXISTENT - WITHOUT A DROP OF OIL LEAKING ANYWHERE? I NOW HAVE TO CARRY 3-4 QUARTS OF OIL WITH ME EVERYWHERE I GO JUST IN CASE THE CHECK ENGINE LIGHT COMES ON. GM SHOULD DO THE RIGHT THING AND ISSUE A RECALL. WARNING: IF YOU DRIVE A CHEVY YOU BETTER KEEP 4 QUARTS OF OIL WITH YOU AT ALL TIMES IN THE EVENT THIS HAPPENS TO YOU. NOT IMMEDIATELY PULLING-OVER & FILLING THE OIL LEVEL BACK TO PROPER LEVEL MAY DESTROY YOUR ENGINE. FIX THIS EFM ISSUE > LOSS OF OIL, AS IT HAS BEEN GOING ON FOR YEARS AND STILL PERSISTS AFTER 2 COMPLETE MODEL CHANGEOVERS. THIS MAJOR MALFUNCTION IS THE RESULT OF THE EFM SYSTEM DUMPING THE OIL INTO THE EXHAUST & THE CATALYTIC CONVERTER BURNING IT AWAY. THAT IS THE ONLY PLAUSIBLE EXPLANATION FOR LOSING SO MUCH OIL WITHOUT WARNING AND WITHOUT A DROP OF OIL BEING FOUND ANYWHERE OUTSIDE THE ENGINE OR UNDERNEATH THE ENGINE COMPARTMENT OR CHASSIS. *TR

THE DASH HAVE THREE CRACKS IN IT EVEN THOUGH I KEEP IT COVERED. I SEE THAT THERE ARE SEVERAL COMPLAINTS ABOUT THE SAME SITUATION AND YET CHEVROLET AND OR THE DEALERS REFUSE TO REPLACE IT. I WAS TOLD IT WOULD COST BETWEEN $200.00 TO $250.00 TO REPLACE IT. CHEVROLET KNOW OF THIS AND YET DO NOT WANT TO TAKE RESPONSIBILITY. EVEN THE DEALER STATED THE THIS IS A DEFECT.

I HAVE BEEN HAVING PROBLEMS WITH MY CHEVY SILVERADO TRUCK, TEXAS EDITION, IT HAS 23,800 MILES ON IT I PURCHASED IT WITH O MILES, I ADHERE TO OIL CHANGES AND ANY REPAIRS IN TIMELY MANNER. MY TRUCK HAS BEEN IN SERVICE DEPARTMENT TWICE FOR THE SAME ISSUE, WHEN THE TRANSMISSION IS SWITCHING GEARS, IT MAKES A CLUNKING NOISE WHILE DRIVING IT, IT FEELS LIKE SOMEONE IS BUMPING THE REAR OF TRUCK. THE REPAIRS INCLUDE TRANSMISSION HARD SHIFTING 2 - 3 TIMES, RR UPPER CONTROL VALVE BODY AND SPACER PLATE REPLACED, RESET TRANSMISSION, 1 2 3 4 CLUTCH REGULATOR VALVE BINDING IN BORE. ALSO REPLACED SPRINGS, SECOND SERVICE THE U JOINTS ANITSD YOKE REPLACED, MY TRUCK CONTINUES WITH SAME PROBLEM, PLEASE LOOK IN TO THIS ITS HORRIBLE & VERY DISAPPOINTING WHY CAN`T THEY FIX IT, MY TRUCK SOUNDS LIKE AN OLD VEHICLE I THINK SOMETHING IS WRONG WITH SUSPENSION. I`M DESPERATE TO FIND AN ANSWER. ITS AN EXPENSIVE TRUCK TO BE DEALING WITH THESE ISSUES. *TR

BRAKES ARE SPONGY DOES NOT STOP TRUCK UNTIL PUMPED,POWER TRAIN CLUNKING NOISE WHEN TURNING AND SHIFTING,ELECTRICAL AT TIMES DASH LIGHTS DIM AT ANY GIVEN TIME, MANY OTHER COMPLAINTS VERY ROUGH RIDE, TRANS SHIFTS VERY HARD, WHEN COMING TO A TRAFFIC LIGHT RUNS ROUGH. HAS BEEN TO DEALER ONCE AND LAST THURSDAY GOT A CALL FROM GM THE DEALERSHIP HAS NOT RESPONDED TO MY PROBLEMS. *TR

ATTEMPTED TO PUT OUT FIRE THRU DRIVERS SIDE FRONT WHEEL WELL BUT WAS UNSUCCESSFUL. CALLED 911. ENTIRE CAB AND ENGINE COMPARTMENT WAS CONSUMED BY THE TIME 911 ARRIVED. *TR

MY 2012 SILVERADO LS HAS 22,000 MILES. IT IS A SHAME BECAUSE IT IS A BEAUTIFUL TRUCK, BUT THE FRAME LOOKS TERRIBLE. IT IS NOT A LITTLE RUST HERE AND THERE. THE RUST IS LITERALLY ALL OVER THE FRAME. THERE IS MORE OF THE FRAME WITH RUST THAN WITHOUT. THE FRAME IS VERY EASY TO SEE. UNFORTUNATELY FOR GM, MY TRUCK IS A ROLLING BILLBOARD AND THE RUST IS GETTING WORST EVERY YEAR.

EXTERIOR DOOR HANDLES ARE CHEAP PLASTIC, SAFETY CONCERN BECAUSE WILL BE UNABLE TO OPEN DOOR IN EMERGENCY.

THIS TRUCK HAS CHATTERED, HOPPED, AND HAD BAD BRAKES AS SOON AS WE DROVE THE TRUCK OFF OF THE LOT. WHEN WE WENT WITH THE DEALER WHO SOLD US THE TRUCK, MY HUSBAND SAID WHY IS IT VIBRATING & HE TOLD US THAT IT WAS IN THE TIRES FROM "SITTING". IT HAS HAD 2 NEW WHEELS & NUMEROUS BRAKES, PADS, ROTORS, CALIPERS, DRUMS. & IT STILL VIBRATES. THE DEALERSHIP HAS EVEN PUT ANOTHER TRUCKS TIRES & RIMS ON THE TRUCK & IT STILL VIBRATES. THIS IS UNACCEPTABLE FOR A NEW VEHICLE. WHEN I CALLED THE GM DISTRICT SPECIALIST ON 5/29/13 SHE TOLD ME THAT THE VIBRATION & HIT & MISS ACCELERATION WAS A CHARACTERISTIC OF THE TRUCK. $40,000 TRUCK & IT IS NOT A VERY GOOD RIDE. *TR

TL* THE CONTACT OWNS A 2012 CHEVROLET SILVERADO. THE CONTACT STATED THAT THE ACCELERATOR PEDAL WAS DEPRESSED, THE VEHICLE FAILED TO MOVE. THE VEHICLE WAS TAKEN TO THE DEALER WHO WAS UNABLE TO DUPLICATE THE FAILURE. THE VEHICLE HAD NOT BEEN REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED. THE APPROXIMATE FAILURE MILEAGE WAS 1,000.

WHEN YOU TRY TO ACCELERATE, THE TRUCK DOES NOT RESPOND. THE TRUCK ACCELERATION FEELS LIKE THEIR IS A FLAT SPOT IN THE ACCELERATION. THIS IS VERY DANGEROUS. SEVERAL OF MY FAMILY MEMBERS HAVE ALMOST GOTTEN IN TERRIBLE T-BONE ACCIDENTS DUE TO THIS MALFUNCTION. BROUGHT THE TRUCK TO THE LOCAL DEALERSHIP & THE SAID THEY REPLACED THE THROTTLE POSITION SENSOR & IT IS WORSE NOW. *TR

ENGINE LIGHT WOULD COME ON AND ENGINE WOULD NOT BE OPERATING PROPERLY.APEARED TO BE MISFIRING. IT WAS TAKEN IN TO THE DEALERSHIP FOUR DIFFERENT TIMES AND DIAGNOSED WITH CYLINDER MISFIRE OIL FOULED SPARK PLUG EACH TIME. PROBLEM PERSISTED UNTIL WE WERE INFORMED BY THE DEALERSHIP AFTER THE WARRANTY EXPIRED IT WOULD NEED A NEW ENGINE. MANUFACTURE AND DEALERSHIP WERE UNHELPFUL AND DID NOT ACCEPT RESPONSIBILITY FOR A DEFECTIVE ENGINE. THERE IS A CLASS ACTION LAWSUIT PENDING FOR THIS MODEL AND TYPE ENGINE WITH OTHERS EXPERIENCING THE SAME PROBLEMS.

THIS FAULT HAS BEEN PRESENT SINCE THE FIRST WEEK OF OWNING MY 2012 SILVERADO CREW CAB LT EQUIPPED WITH THE 5.3 LITER AND 6 SPEED TRANSMISSION. UPON SLOWING TO A STOP, THE TRUCK SURGES AND LUNGES FORWARD AS THE TRANSMISSION DOWNSHIFTS BETWEEN GEARS, AND IS MOST NOTICEABLE WHEN TRAVELING UP OR DOWN HILLS. THE FAILURE MODE CAN BE TECHNICALLY DESCRIBED AS THE FOLLOWING SEQUENCE OF EVENTS: 1. SLOWING TO A STOP (COASTING), ENGINE BEGINS RIDING OUT 4TH GEAR (FOR EXAMPLE). 2. APPLY BRAKES; TRANSMISSION DOWNSHIFTS TO 3RD, AND ENGINE RPMS INCREASE TO COMPENSATE FOR DYNAMICS OF SHIFTING. TORQUE CONVERTER IMMEDIATELY ENGAGES THE ENGINE TO THE WHEELS. AS THE ENGINE IS AT A HIGH RPM LEVEL, AN ACCELERATING LOAD IS APPLIED TO THE WHEELS, WHILE BRAKING. 3. THIS CREATES AN UNINTENDED SURGE OF ACCELERATION, WHICH IS THEN ALSO NOTICEABLE THROUGH THE REMAINING GEARS (TRUCK SLOWS, THEN SURGES, SLOWS, THEN SURGES UNTIL COMING TO A COMPLETE STOP). I HAVE ALSO VERIFIED THAT THIS IS A COMMON COMPLAINT IN THE ONLINE FORUMS, AND MANY PEOPLE ARE EXPERIENCING THIS FAULT. IN FACT, ONE OF THE DEALERSHIPS ACTUALLY INFORMED ME THAT MANY OF HIS CUSTOMERS GO TO AN AFTERMARKET SHIFT PROGRAM TO AVOID THE ISSUE. I HAVE TRIED THIS, AND IT DID NOT RESOLVE THE ISSUE. EACH TIME THE TRANSMISSION IS EVALUATED AT THE DEALERSHIP, THE DAPS (DIGITAL PARAMETERS) ARE "RESET" (ACCORDING TO THE SERVICE SHOPS), AND THE TRUCK DRIVES FANTASTICALLY. HOWEVER, ROUGHLY 10 MILES LATER, IT IS BACK TO EXHIBITING THE EXACT SAME FAILURE MODE. DEALERSHIP HAS TROUBLESHOOT THIS FAULT EXTENSIVELY, AND HAS STATED THAT THIS MODE OF OPERATION IS "NORMAL" - I ASKED THEM TO EXPLAIN HOW FORWARD ACCELERATION DURING BRAKING WAS "NORMAL", AND OF COURSE THEY COULD NOT. *TR

REAR HEAD RESTS DO NOT HAVE A LOCKING MECHANISM TO KEEP THEM LOCKED IN PLACE WHEN RAISED. THIS ALLOWS THE REAR HEAD RESTS TO FALL TO THE LOWEST POSITION WITH VERY LITTLE FORCE. GENERAL MOTORS HAS STATED THAT THIS IS NORMAL AND WITHIN SPECIFICATIONS. OWNERS ARE ADVISED TO INSPECT THE REAR HEAD RESTS TO DETERMINE FOR THEMSELVES WHETHER THIS POSES AN ACCEPTABLE RISK TO THEIR PASSENGERS. ADULTS RIDING IN THE REAR SEAT SHOULD BE ADVISED OF THIS CONDITION. *TR

DASH CRACKING AROUND PASSENGER AIRBAG AND DRIVER SIDE INSTRUMENT PANEL.

TL* THE CONTACT OWNS A 2012 CHEVROLET SILVERADO. WHILE DRIVING APPROXIMATELY 10 MPH, THE VEHICLE SUDDENLY ACCELERATED INDEPENDENTLY. THE CONTACT DEPRESSED THE BRAKE PEDAL AND WAS ABLE TO STOP THE VEHICLE. THE FAILURE RECURRED TWICE. THE VEHICLE WAS TAKEN TO THE DEALER FOR DIAGNOSTIC TESTING. THE TECHNICIAN WAS UNABLE TO DIAGNOSE THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 2,500.

WAS DRIVING UP TO THE STOP SIGN. IT FELT LIKE THE TRANSMISSION WAS SHIFTING HARD. SORTA LIKE JERKING. *TR

I BOUGHT MY 2012 TEXAS EDITION SILVERADO AUGUST 4, 2012 THE TRANSMISSION STARTED RESPONDING ABNORMAL IMMEDIATELY AFTER LEAVING THE DEALERSHIP IT HAD 135 MILES ON IT BEFORE I BOUGHT IT I HAVE 32K MILES NOW AND NOTHING HAS CHANGE ALL THE SAME ISSUES BUT THEY SEEM TO BE GETTING WORST. MY TRANSMISSION HAS A HARD TIME SHIFTING NO MATTER WHAT, UP, DOWN, TURN, FORWARD ALL NORMAL DRIVING MANEUVERS. WHEN IT DOES TRY AND SHIFT THE ENGINE CLATTERS WHICH IS EXTREMELY RIDICULOUS I'VE HAD SEVERAL SILVERADO'S AND THE LAST ONE THAT CLATTER THIS WAY WAS A 1978 WITH PROBABLY OVER 300,000(EXPECTED). MY TRANSMISSION DOES AS STATED BY OTHERS THE COMING TO A STOP SIGN AND APPLYING THE BRAKES THE TRUCK WILL LAUNCH FORWARD UNEXPECTEDLY AND SHIFT EXTREMELY HARD THIS IS THE FIRST NEW VEHICLE I'VE EVER BOUGHT THE LAST 4 WERE ALL SILVERADO FROM 78-94 AND THEY DIDN'T DO THIS. THIS TRUCK ALSO WEARS THE OUTER EDGE OF MY TRES NO MATTER HOW MANY ALIGNMENTS AND BALANCE AND ROTATING I GET DONE. YOU MAY SAY YOUR TIRE YOUR FAULT BUT I'VE LOOKED AT OVER 40 2012 SILVERADO'S IN PARKING LOTS AND SAW THE EXACT SAME WEAR PATTERN THE OWNERS ARE PROBABLY NOT THE TYPE TO CHECK OR CARE. THE BIGGEST CONCERN IS THE $30,000 I PAID FOR THIS THING AND EXPECTED IT TO RUN FOR THE NEXT 20 YEARS BUT I'M AT LESS THAN 2 YEARS AND IT FEELS LIKE THE TRANSMISSION AND ENGINE ARE GOING TO JUMP OUT AND FLY THROUGH AN INTERSECTION LEAVING ME AT A GREEN LIGHT. IF I WERE TO LET ANY CHEVY "BIG SHOT" DRIVE THIS FOR 1 WEEK AS THEIR DAILY DRIVER (IT'S MY DAILY) THEY WOULD PROBABLY STOP DRIVING IT ON DAY 1 AND ASK ME HOW I'VE DONE IT FOR ALMOST 2 YEARS. MY REPLY WOULD BE I DON'T HAVE THE MONEY TO GET ANOTHER ONE AND YOU "BIG SHOT" NEED TO GET THIS FIXED. ACTIVE DUTY MILITARY (NO MONEY) OVER WORKED UNDER PAID. TOOK MY SAVINGS BOUGHT A TRUCK THAT I WAITED 23 YEARS TO BUY AND THEN THE THING IS IN WORST SHAPE THAN THE 1994 EXTENDEDCAB I HAD. *TR

TL* THE CONTACT OWNS A 2012 CHEVROLET SILVERADO 1500. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 45 MPH, THE VEHICLE SUDDENLY ACCELERATED INDEPENDENTLY. THE CONTACT DEPRESSED THE BRAKE PEDAL BUT THE VEHICLE WOULD NOT RESPOND. THE VEHICLE WAS TAKEN TO THE DEALER FOR DIAGNOSTIC TESTING THREE DIFFERENT TIMES. THE TECHNICIANS WERE UNABLE TO DIAGNOSE THE FAILURE. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND HAD AN ENGINEER FURTHER INSPECT THE VEHICLE. THE VEHICLE WAS NOT REPAIRED. THE VIN WAS NOT AVAILABLE. THE APPROXIMATE FAILURE MILEAGE WAS 6,900. KMJ

THERE IS A VERY HIGH PITCH NOISE THE IS EMITTED FROM BEHIND THE DASH. THIS NOISE IS DISTRACTING TO THE POINT THAT MY WIFE CAN NOT RIDE IN THE TRUCK LET ALONE DRIVE IT. I HAVE TAKEN THE TRUCK TO THE DEALER AND WAS TOLD BY THE SERVICE DEPARTMENT THAT GENERAL MOTORS IS AWARE OF THIS NOISE AND IT IS ACCEPTABLE. *TR

I HAVE HAD A RECURRING PROBLEM WITH MY NEW 2012 CHEVROLET SILVERADO 1500 LT (5.3 LITER ENGINE) GOING INTO "REDUCED ENGINE POWER MODE" WHICH ALSO RESULTS IN THE DISABLING OF STABILITY CONTROL AND TRACTION CONTROL. THIS IS A DANGEROUS CONDITION IN THAT IT RESULTS IN A LOSS OF POWER WHILE OPERATING THE VEHICLE UPON THE ROADWAY. AN AUTHORIZED REPAIR FACILITY HAS REPLACED THE NUMBER ONE AND TWO THROTTLE SENSORS, THE ACCELERATOR PEDAL ASSEMBLY, THE THROTTLE BODY, THE ALTERNATOR, THE COMPUTER, AND A LARGE GROUND WIRE BEHIND THE DASH. A GM ENGINEER WAS FLOWN IN AND NOW THE REPAIR CENTER IS REPLACING THE ENGINE WIRING HARNESS. THE VEHICLE (WHICH WAS PURCHASED LESS THAN THREE MONTHS AGO) HAS BEEN OUT OF SERVICE FOR APPROXIMATELY 30 DAYS. IN RESEARCHING THIS MATTER I HAVE FOUND THAT CHEVY HAS HAD AN ONGOING PROBLEM WITH THIS IN VARIOUS VEHICLES IN ITS PRODUCT LINE SINCE 2003. ALTHOUGH SEVERAL SERVICE BULLETINS HAVE BEEN PRODUCED THERE DOES NOT SEEM TO BE A CONSENSUS REGARDING THE CAUSE OF THIS PROBLEM. ALL OF THE PARTS ASSOCIATED WITH TROUBLE CODES C0242, P2127, AND P2138 HAVE BEEN REPLACED WITHOUT RESULT. THIS CONDITION COULD RESULT IN THE AFFECTED VEHICLES BEING REARENDED, OR, BECAUSE OF THE LOSS OF STABILITY AND TRACTION CONTROL, RESULT IN A ROLL OVER. THIS NEEDS TO BE ADDRESSED IMMEDIATELY. *JS

HAPPENED DRIVING HOME AFTER BUYING VEHICLE. TRANSMISSION SHIFTS HARD FROM A COMPLETE STOP AS 1ST GEAR WAS BEING ENGAGED. DROVE IT UNTIL BREAK IN PERIOD WAS OVER AND TOOK IT BACK TO THE DEALER WERE THE TRANSMISSION BODY AND VALVES WERE REPLACED. NOW GETTING MORE PROBLEMS WITH THE TRANSMISSION SHIFTING BETWEEN GEARS AT A SPEED OF 35-45 MPH. TRANSMISSION DISENGAGES AND I HAVE NO POWER GOING TO THE WHEELS, LIKE IT SHIFTS TO NEUTRAL FOR A 5-10 SECONDS. THIS WILL CAUSE AN ACCIDENT IF TRANSMISSION DOES NOT REENGAGE WHILE DRIVING IN TRAFFIC. YOU WILL GET REAR ENDED. *TT

SAFETY CONCERN- POTENTIAL TRAILERING ACCIDENT!!! IT APPEARS THAT CHEVROLET/GM HAS CHANGED THE WIRING IN THEIR VEHICLES SO THAT ELECTRIC TRAILER BRAKE CONTROLLERS NO LONGER ILLUMINATE THE TRAILER BRAKE LIGHTS WHEN THE ELECTRIC BRAKE CONTROLLER IS OPERATED INDEPENDENTLY FROM THE VEHICLE BRAKES. ALL BRAKE LIGHTS WORK FINE WHEN THE FOOT BRAKE IS APPLIED BUT NO BRAKE LIGHTS ILLUMINATE WHEN THE CONTROLLER OVERIDE IS APPLIED TO OPERATE THE TRAILER BRAKES INDEPENDENTLY. THERE ARE TIMES WHEN TRAILERING THAT ONE ONLY WISHES TO USE THE TRAILER BRAKES TO SETTLE DOWN SWAYING OR ON LONG DOWN HILL GRADES. 2012 VEHICLES ARE NOT WIRED SO THAT BRAKE LIGHTS ALSO WORK OFF THE CONTROLLER OVERRIDE SWITCH. I HAVE BEEN TOWING FOR OVER 26 YEARS AND BRAKE LIGHTS HAVE ALWAYS WORKED BOTH ON THE FOOT BRAKE AND CONTROLLER OVERRIDE BRAKE SWITCH. THIS IS A POTENTIAL ACCIDENT WAITING TO HAPPEN. IF ONE APPLIES THE TRAILER BRAKES ALONE WITH NO BRAKE LIGHTS ILLUMINATING, THIS COULD CAUSE ANOTHER VEHICLE TO SLAM INTO THE BACK OF THE TRAILER AND TOW VEHICLE CAUSING A CRASH. CHEVROLET STATES THEY CANNOT CONNECT THE TRAILER CONTROLLERS TO OPERATE THE BRAKE LIGHTS AS IT WOULD BACK FEED POWER INTO THE ELECTRONICS OF THE VEHICLE VOIDING ANY WARRANTY ON THE VEHICLE. TRAILER BRAKES LIGHTS ONLY WORK AS CONNECTED TO THE VEHICLE WIRING WHEN STEPPING ON THE FOOT BRAKE. *KB

TL* THE CONTACT OWNS A 2012 CHEVROLET SILVERADO 1500. WHILE DRIVING APPROXIMATELY 35 MPH, THE ENGINE SHOOK UNCONTROLLABLY WITHOUT WARNING. THE CONTACT STATED THAT THE FAILURE RECURRED AFTER EVERY 10,000 MILES. THE VEHICLE WAS TAKEN TO A DEALER WHERE IT WAS DIAGNOSED THAT THERE WAS A MISFIRE ON A CYLINDER AND THE SPARK PLUGS NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 20,000.

THIS IS ABOUT THE SAFETY ISSUES WITH A SET OF GOODYEAR EAGLES LS-2 TIRES. WITH ONLY 1300 MILES ON THE VEHICLE, I HAVE ALREADY SLID THREE OR FOUR DIFFERENT TIMES, INCLUDING SLIDING INTO THE MEDIAN TWICE. I HAVE NO CONFIDENCE IN THESE TIRES TO STAY ON THE ROAD OR WHEN PULLING OUT OR GOING AROUND A CURVE. THESE TIRES SHOULD NOT BE ON THE ROAD. *TR
