NHTSA Complaint #10614739 — 2011 CHEVROLET TRAVERSE

VEHICLE WAS 2011 CHEVY TRAVERSE W/ AWD WITH HISTORY (FOUR INSTANCES) OF ENGINE OIL LEAKS/REQUIRING ENGINE REMOVAL AND REINSTALL. VEHICLE WAS ON INTERSTATE WHEN AWD/VEHICLE STABILITY CONTROL LIGHTS WENT ON. DIC INDICATED 'SERVICE STABILTRACK', 'SERVICE AWD' AND 'AWD DISABLED'. AT THAT TIME, VEHICLE WAS 'CHUGGING' BUT SHORTLY AFTER CHUGGING GOT MUCH WORSE TO THE EXTENT THAT THE VEHICLE COULD NOT ACCELERATE OR MAINTAIN SPEED AT CRUISE, OR WITHOUT CRUISE UP NORMAL HILLS ON AN INTERSTATE. WHEN GAS PEDAL WAS PRESSED FURTHER, RPM/SPEED WOULD INCREASE BUT THEN DROP SHARPLY (500-1000RPM) MULTIPLE TIMES AND NO FURTHER POWER COULD BE APPLIED. VEHICLE SLOWED DOWN TO ABOUT 50MPH AT THE TOP OF A HILL. HAPPENED FOR THE NEXT 15-20 MILES UNTIL IT COULD BE PULLED OVER. VEHICLE WAS TAKEN IN ONCE RIGHT AFTER ORIGINAL OCCURRENCE, ALL THREE LIGHTS HAD GONE OFF AT POINT AND VEHICLE DROVE NORMALLY AFTER THAT. SERVICE CENTER INDICATED A WHEEL CENSOR (FRONT RIGHT) WAS READING DEFECTIVE INFORMATION. THEY CLEANED 'DUST' FROM THE SENSOR. HAPPENED AGAIN ABOUT TWO WEEKS LATER, SIMILAR CIRCUMSTANCES/RESULTS. SERVICE CENTER INDICATED WHEEL SENSOR WAS BAD, THEY REPLACED (AT MY COST) AND HAD NO FURTHER INSTANCES FOR ABOUT FOUR MONTHS. SIMILAR SITUATION HAPPENED AGAIN TODAY (7/19/2014, CONDITIONS AND RESULTS). HOWEVER, THE ENGINE CHUGGING WAS MUCH WORSE AND VEHICLE COULD NOT BE DRIVEN SAFELY ON THE INTERSTATE, WOULD NOT ACCELERATE OR MAINTAIN SAFE INTERSTATE SPEED. *TR
