2007 Chevrolet Suburban Power Train

TL* THE CONTACT OWNS A 2007 CHEVROLET SUBURBAN 1500. WHILE DRIVING APPROXIMATELY 30 MPH, THE VEHICLE FAILED TO ACCELERATE WHEN THE ACCELERATOR PEDAL WAS DEPRESSED AND THE VEHICLE BEGAN TO REVERSE. THE CONTACT HAD TO IMMEDIATELY PLACE THE SHIFT LEVER INTO THE PARK POSITION. THE FAILURE OCCURRED FOUR TIMES. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHO STATED THAT THE TRANSMISSION NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED, BUT THE FAILURE PERSISTED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 50,000.

THE FORWARD SPRAG UNIT BROKE WHICH ENDED UP NOT ONLY CAUSING THE VEHICLE TO COME OUT OF DRIVE WHILE WE WERE DRIVING BUT ALSO CAUSED SIGNIFICANT ENOUGH DAMAGE TO THE TRANSMISSION TO REQUITE AN ENTIRE REBUILD. FAULTY TRANSMISSIONS ARE A VERY COMMON ISSUE WITH THIS VEHICLE, AND THE TAHOE, YUKON AND BECAUSE THE COMPANY REFUSES TO BACK THEIR PRODUCTS AND RECALL THE ISSUE, IT ENDS UP BECOMING A HUGE FINANCIAL BURDEN ON A FAMILY. THANKFULLY THERE WAS NO ONE FOLLOWING DIRECTLY BEHIND US WHEN THIS HAPPENED OR IT COULD HAVE BEEN MUCH WORSE. CHEVROLET NEEDS TO TAKE NOTE AND STAND BEHIND THEIR PRODUCTS. CONSUMERS HAVE A RIGHT TO EXPECT A QUALITY VEHICLE THAT SHOULD LAST WELL BEYOND 100K MILES WITHOUT REQUIRING THIS KIND OF MAJOR REPAIR. NOTE THAT GM IS SO AWARE OF THIS SAFETY PROBLEM, THEY ACTUALLY UPDATED THEIR INPUT SPRAG ON LATER CARS TO MAKE THEM STRONGER. THATS RIGHT, THEY HAVE UPDATED THE COMPONENT BUT REFUSE TO RECALL THE ONES ALREADY IN VEHICLES THAT WERE WEAK. THE TRANSMISSION SHOP THAT REBUILT MY TRANSMISSION HAD THE EXACT SAME ISSUE ON THE VEHICLE THAT FOLLOWED MINE. THIS SEEMS TO BE A PATTERN WITH GM THAT THE NHTSA SHOULD LOOK INTO. *TR

TRANSMISSION STOPPED WORKING WHILE DRIVING HAD BEEN SLIGHT VIBRATION SEVERAL MONTH PRIOR WHICH WAS REPORTED TO DEALER-HE SAID WHEEL BALANCE-DID NOT HELP ONLY 1ST AND 2ND GEAR WORKED. LOCAL DEALER QUOTED $2,800 TO REPLACE. DEALER HAD THE CAR FOR OVER A MONTH.GM OFFERED TO PAY 45%. I WOULD PAY $1540. WHEN PICKED UP CAR I HAD TO PAY $2300! TOLD THE WARRANTY FROM GM CAUSED THE PRICE TO GO UP. THE CAR STILL HAS A VIBRATION. A CAR WITH 80,000 MILES SHOULD NOT NEED A NEW TRANSMISSION. *TR

TL* THE CONTACT OWNS A 2007 CHEVROLET SUBURBAN 1500. THE CONTACT STATED THAT WHILE DRIVING 45 MPH, THE TRANSMISSION FAILED. THE VEHICLE WAS TOWED TO A TRANSMISSION SPECIALIST FOR INSPECTION WHERE THEY STATED THAT THE TRANSMISSION NEEDED TO BE REPAIRED. THE VEHICLE WAS REPAIRED BUT THE FAILURE RECURRED. THE MANUFACTURER WAS NOTIFIED AND STATED THAT THE FAILURE WAS NOT A COMMON PROBLEM AND THAT THEY COULD PROVIDE NO ASSISTANCE. THE FAILURE MILEAGE WAS 138,000.

MY SUBURBAN WONT SHIFT OR MOVE IN DRIVE OR IN 3RD. IT WILL GO IN TO 2ND AND 1ST AND REVERSE. IT JUST REVS UP WHEN IN DRIVE. I WAS READING ONLINE AND FOUND SEVERAL OTHER PEOPLE TO HAVE THE SAME PROBLEM WITH THIS VEHICLE. THIS SHOULD BE A RECALL ON THE TRANSMISSION OR DEFECTIVE PARTS CAUSING THIS IN THE TRANSMISSION. *TR

I WAS PROCEEDING FROM AN INTERSECTION AND TURNING LEFT, I REACHED A SPEED OF 15-20 MPH AND THERE WAS A "BANG" AND A "CLUNK" AND THE POWER TO THE WHEELS WAS GONE, I COASTED TO THE ROADSIDE AND WAS UNABLE TO PUT THE CAR IN "D" DRIVE OR "3" IT WAS AS IF IT WAS IN NEUTRAL. I WAS ABLE TO LIMP HOME USING 1ST AND 2ND GEARS. VEHICLE WAS TOWED TO DEALERSHIP FOR A TRANSMISSION REPLACEMENT DUE TO THE FAILURE OF THE FORWARD SPRAG COMPONENT. *TR

ON TWO OCCASIONS AN ERROR MESSAGE THAT READ "SERVICE 4 WHEEL DRIVE" APPEARED ON THE DISPLAY. I MENTIONED THIS TO THE SERVICE DEPARTMENT WHILE THERE FOR AN OIL CHANGE, AND WAS TOLD THAT EVERYTHING CHECKED OUT OKAY, AND THAT I SHOULD DRIVE THE VEHICLE IN 2WD, NOT AUTO. ALSO, I HAVE BEEN HAVING A TRANSMISSION SLIPPAGE ISSUE THAT STARTED BETWEEN 50,000 MILES AND 58,000 MILES AND WAS VERY SPORADIC. WHEN STARTING FROM A DEAD STOP (STOP LIGHT FOR EXAMPLE), THE TRANSMISSION WOULDN'T ENGAGE AS I PRESSED THE ACCELERATOR. AFTER 10 TO 15 SECONDS OF PRESSING MY FOOT ON THE ACCELERATOR, THE TRANSMISSION WOULD FINALLY ENGAGE AND THE VEHICLE WOULD MOVE SLOWLY WITH THE ENGINE REVVING. I MENTION THIS TO THE DEALER WHEN THE VEHICLE HAS APPROXIMATELY 58,000 MILES AND I'M TOLD THAT THEY WILL NEED TO KEEP THE VEHICLE FOR A FEW HOURS AND THERE IS A COST OF $120 PLUS TAX TO PERFORM DIAGNOSTIC TESTING. AS MY SCHEDULE DID NOT ALLOW FOR THIS THAT DAY, I LEFT. THE PROBLEM WAS VERY SPORADIC AT THIS POINT. AT 63,000 MILES I AM DRIVING OVER A MOUNTAIN PASS AND THE DISPLAY READS SOMETHING ALONG THE LINES OF "TRANSMISSION OVERHEATING". I PULL OFF THE ROAD AND WAIT FOR IT TO COOL, THEN MAKE MY WAY HOME. I ENTIRE TRIP HOME THE TRANSMISSION IS SLIPPING BETWEEN ALL GEARS AND SHIFTING HARD IN THE HIGHER GEARS. I TAKE IT INTO THE DEALER FOR DIAGNOSTICS THE NEXT BUSINESS DAY AND I'M TOLD THAT I NEED A NEW TRANSMISSION. I AM ADVISED BY THE DEALER THAT THERE IS "NO EXTERNAL CAUSE FOR THIS FAILURE" AND " THE INNER MECHANISM OF THE TRANSMISSION HAS FALLEN APART AND CANNOT BE REPAIRED". MY POWERTRAIN WARRANTY ENDED 6 MONTHS AGO, SO I FACE A $3,350 BILL FOR THIS REPAIR. AFTER I COMPLAIN TO GM CUSTOMER ASSISTANCE, THEY AGREE TO PAY 30% OF THE REPAIR AND 5 DAYS OF THE RENTAL CAR, BUT I FEEL THEY SHOULD PAY THE ENTIRE AMOUNT. *TR

I HAVE A 2007 CHEVROLET 4WD SUBURBAN LS THAT HAS ITS TRANSMISSION REBUILT BECAUSE THE TRUCK JUST WON'T GO. IT HAS 34K PLUS MILES AND 42 MONTH OLD. I WANTED TO KNOW IF THIS IS COMMON ON THIS KIND OF VEHICLE AND WHY DID IT HAPPEN. *TR

THIRD INCIDENT FOR THIS PROBLEM. WHILE DRIVING IN (D) THE TRANSMISSION WILL DISENGAGE AND THE VEHICLE ENGINE WILL REV UP (3RD & 2ND GEAR) SEEM TO WORK STILL. THIS HAS HAPPENED AT VARIOUS SPEEDS FROM 25 TO 55 MILE PER HOUR. ONLY ONE TIME HAS IT BEEN CLOSE TO AN ACCIDENT WHILE MAKING A LEFT HAND TURN WITH ON COMING TRAFFIC. THE DEALER HAS MADE INSPECTIONS OF THE TRANSMISSION ONCE, THE SECOND TIME THE DEALERSHIP WAS UNABLE TO DUPLICATE THE PROBLEM AFTER KEEPING THE VEHICLE MORE THAN 5 DAYS. THE SUGGESTION FROM THE DEALERSHIP MANAGER WAS TO WAIT FOR IT TO HAPPEN AGAIN, PLACE THE VEHICLE IN EITHER 3RD OR 2ND GEAR DRIVE IT TO THE DEALERSHIP LEAVING IT IN 3RD OR 2ND GEAR APPLYING THE PARKING BRAKE SO THAT THE MANAGER AND A MECHANIC CAN GET INTO THE VEHICLE AND TEST WHAT'S WRONG. THE 3RD TIME THIS HAS HAPPENED IT WAS AROUND 8:30 P.M. AND WE WERE UNABLE TO TAKE IT IN TO BE EXAMINED. THIS PROBLEM IF IT HAPPENS AGAIN WHILE MAKING A TURN OR AT ANYTIME WITH ONCOMING TRAFFIC COULD CAUSE A SERIOUS ACCIDENT. *CN

TL*THE CONTACT OWNS A 2007 CHEVROLET SUBURBAN. SHORTLY AFTER THE VEHICLE RECEIVED A TRANSMISSION FLUSH, IT WOULD NOT MOVE FORWARD IN THE DRIVE POSITION AFTER BEING PLACED INTO REVERSE. THE FOLLOWING DAY, THE CONTACT TOOK THE VEHICLE TO THE DEALER AND THEY REPLACED THREE PLATES, A VALVE, FILTER KIT, AND A GASKET KIT. THE VEHICLE WAS REPAIRED, BUT THE FAILURE RECURRED LESS THAN A YEAR LATER AFTER ANOTHER TRANSMISSION FLUSH WAS PERFORMED. WHILE DRIVING 65 MPH, THE VEHICLE BEGAN TO HESITATE AND THE ENGINE REVVED, BUT THE VEHICLE WAS LOSING SPEED. SHE DROVE TO A REPAIR SHOP AND THE MECHANIC STATED THAT THE TRANSMISSION WAS NOT SHIFTING PAST FIRST GEAR. THE CONTACT TOOK THE VEHICLE BACK TO THE DEALER THAT PERFORMED THE ORIGINAL REPAIR, BUT THEY STATED THAT IT WAS NO LONGER UNDER WARRANTY AND WAS NOT THEIR RESPONSIBILITY. THROUGH ONLINE RESEARCH, THE CONTACT FOUND NUMEROUS COMPLAINTS ABOUT THIS SAME DEFECT. SHE BELIEVES THAT A RECALL SHOULD BE ISSUED. THE FAILURE MILEAGE WAS 65,414 AND CURRENT MILEAGE WAS 123,000.

THE CONTACT HAS BEEN TO TWO DIFFERENT DEALERS. CHEVROLET STATED THAT NOTHING COULD BE DONE. THE FAILURE MILEAGE WAS 4,000 AND CURRENT MILEAGE WAS 12,500.

TL* THE CONTACT OWNS A 2007 CHEVROLET SUBURBAN. THE CONTACT STATED THAT THE 4-WHEEL DRIVE SHIFT INDICATOR REACHED TEMPERATURES IN EXCESS OF 100 DEGREES AND COULD CAUSE A BURN TO THE TOUCH. THE MANUFACTURER AND A CHEVROLET DEALER WERE AWARE, AND STATED THAT THIS WAS NORMAL AND THERE WAS NOTHING TO REPAIR. THE 4-WHEEL DRIVE INDICATOR WAS ALWAYS HEATED, AND THE CAR HAD A BURNING SMELL BECAUSE OF IT AND GOT WORSE WHILE DRIVING. *AK
