THIS IS AN UPDATE TO COMPLAINT 10280929 FOR A 2008 BUICK ENCLAVE AWD AFTER FUEL EFFICIENCY REACHING AN ALL-TIME HIGH OF 17MPG COMBINE HWY&CITY, WITHIN WEEKS IT BEGAN DROPPING AND SETTLED BETWEEN 14-15 MPG. WATER LEAKS THAT BEGAN DUMPING CUP FULL OF WATER ON OCCUPANTS LAST YEAR FIXED. MORE DEFINITE HESITATION BETWEEN GEARS CONTINUES, AS WELL AS MOMENTARY LAPSES IN POWER RELATIONSHIP BETWEEN PEDAL AND ENGINE. LAST MONTH A WHIRRING SOUND STARTED THAT WAS ASSOCIATED WITH TURNING THE CAR. THE SOUND WOULD RISE DURING ACCELERATION AND FALL DURING DE-ACCELERATION. BREAK JOB TOOK CARE OF IT (ALTHOUGH I DOUBTED THE DEALER'S ASSESSMENT) UNTIL YESTERDAY. THE WHIRRING HAS RETURNED, ALBEIT INTERMITTENTLY. AFTER 3 YRS I KNOW THAT IF A PROBLEM CAN'T BE REPLICATED ON TEST DRIVE OR SHOW UP AS CODES ON A COMPUTER--THE DEALERSHIPS (AND I HAVE BEEN TO 3 OVER THE YEARS) WILL DO NOTHING. MY SOLUTION IS TO TURN...

WITHIN THE LAST FOUR MONTHS, I HAVE NOTICED A VIBRATING NOISE AS PART OF MY STEERING. MY MAJOR COMPLAINT IS A VERY LOUD SHARP WHISTLING NOISE COMING FROM MY ENGINE AFTER DRIVING IT FOR A SHORT TIME. THE SCREECHING, WHISTLING CONTINUES WHILE IT IS IDLING FOR LONG PERIODS OF TIME. I AM CONCERNED OF WHAT IT IS AND ALSO FIND IT NOT ACCEPTABLE TO HAVE TO PUT UP WITH THE NOISE CONSTANTLY, ESPECIALLY BEING ONLY 2 YRS. 4 MO. OLD AND LESS THAT 25,000 MILES. OBVIOUSLY IT IS A DEFECT BY GM AND THEY ARE RESPONSIBLE FOR FIXING IT ASAP AS I'M NOT SURE IF THE NOISE IS ALL THERE IS TO IT AS FAR AS SAFETY. THE TECHNICIANS AT THE DEALERSHIP WORKED ON IT, PUT IN A NEW DEFIBULATOR, TOOK IT BACK OUT AND SAID THEY CALLED GMC. ACCORDING TO THE TECHNICIAN, GM SAID ALL ENCLAVES MAKE THE SAME...

08 BUICK ENCLAVE NORMALLY DOWNSHIFTS AND UPSHIFTS ALL THE WAY UP A HILL. TOOK IN THREE TIMES AND THEY SAID EVERYTHING CHECKS OUT NORMAL, JUST DRIVE IT. THEN DRIVING OUT TO ARIZONA, IT STARTED OUT DOWNSHIFTING AT THE START OF A HILL AND UPSHIFTING AT THE TOP OF THE HILL LIKE A NORMAL CAR. THEN ONCE EVERY FIVE TO TEN HILLS IT WOULD NOT UPSHIFT AT THE TOP OF THE HILL UNTIL I SHUT OFF THE CRUISE CONTROL. ONCE I WENT FIVE MILES DOWNHILL BEFORE I SHUT OFF THE CRUISE AND IT UPSHIFTED. I TOOK IT IN TO THE DEALER, BUT THE FEW MILES THEY DROVE IT, THEY COULD NOT MAKE IT HAPPEN. THEY SAID THERE WERE NO CODES SO THERE WAS NOTHING THEY COULD DO, SO JUST DRIVE IT LIKE IT IS, AS ITS STILL UNDER WARRANTY. IT HAD ALSO HAPPENED ONLY ONCE BEFORE WHEN IT WAS NEW,BUT THEY...

BASICALLY COMPUTER CHECKS AND ADJUSTMENTS WERE DONE. FINALLY, LAST MONTH A VALVE JOB WAS DONE, AS WELL AS SOME TRANSMISSION WORK AND NOW MY FUEL EFFICIENCY IS IMPROVING.

2008 BUICK ENCLAVE THAT HAS HAD TRANSMISSION PROBLEMS FOR 8 MONTHS (NEW CAR WAS PICKED UP IN AUGUST OF 2007). AFTER SEVERAL SERVICE ATTEMPTS TO FIX THIS PROBLEM, IT STILL DOESN'T PERFORM LIKE IT SHOULD. TODAY WHEN DRIVING THE CAR THE ENGINE WAS RACING TO OVER 4,000 RPM WHILE DRIVING DOWN A 35 MPH ROAD -- THOUGHT THE THING WAS GOING TO BLOW UP BECAUSE IT WOULDN'T SHIFT INTO THE NEXT GEAR. ALSO HAD WATER (FROM RAIN) ON THE INSIDE OF THE CAR AFTER IT RAINED DUE TO FAULTY RAIL CONNECTORS (NOT SEALED) ON TOP OF CAR. *TR
