NHTSA Complaint #11297962 — 2011 BUICK LACROSSE

OUR FAMILY'S 2011 BUICK LACROSSE ONLY HAS 57K MILES ON IT, AND THE ENGINE ALREADY HAS PERMANENT IRREVERSIBLE DAMAGE FROM A MANUFACTURER OVERSIGHT IN WHICH THE TIMING CHAIN "SKIPS TIME." WHILE DRIVING ON THE HIGHWAY, THE CAR UNPREDICTABLY LOST ALL POWER, INCLUDING POWER BRAKES AND POWER STEERING. I QUICKLY MUSCLED THE CAR TO THE SHOULDER AND CAME TO A COMPLETE STOP, BUT THIS CREATED A VERY DANGEROUS SITUATION FOR OUR FAMILY AS WE WERE FORCED TO CROSS TRAFFIC, AT SPEED, TO REACH THE ROAD SHOULDER. A DAY PRIOR TO THIS INCIDENT THE VEHICLE WENT INTO "REDUCED POWER" MODE WHILE TRAVELING UPHILL, CUTTING SPEED FROM 55MPH TO 35MPH, BACKING UP TRAFFIC. CARS WERE PASSING AND HONKING IN A DOUBLE YELLOW-LINED STRETCH OF ROAD. WE SUBSEQUENTLY SHOULDERED THE CAR, SHUT OFF ITS POWER AND IT SEEMED TO BE OPERATING PROPERLY UNTIL OUR DESTINATION, BUT WE ONLY HAD 3 MILES LEFT TO TRAVEL. THE TIMING GEAR IS PRESSED-ON INSTEAD OF KEYED-ON. THIS CAN CAUSE THE TIMING CHAIN TO "SKIP TIME," DAMAGING THE ENGINE AND CAUSING ERRATIC ENGINE BEHAVIOR. OUR MECHANIC HAS SEEN OUR EXACT ENGINE ISSUE WITH THE 3.6L 6-CYL ENGINES IN VARIOUS OTHER GM VEHICLES. THE PROBLEM IS WIDESPREAD ENOUGH TO CAUSE ENGINE REBUILD COMPANIES TO KEY-ON THE TIMING GEAR, INSTEAD OF GM'S TYPICAL PRESS-ON PROCESS. OUR MECHANIC ADVISES THAT KEYING-ON THE TIMING GEAR IS KNOWN TO FIX THE ORIGINAL ISSUE OF THE TIMING CHAIN DANGEROUSLY "SKIPPING TIME." ONE SUCH COMPANY, RECOMMENDED BY OUR MECHANIC, IS JASPERENGINES.COM. I HOPE THAT THE NHTSA CAN INVESTIGATE THIS ISSUE AND HOLD GM ACCOUNTABLE FOR THIS DANGEROUS OVERSIGHT FOR WHICH GM FAILS TO ACKNOWLEDGE OR ADDRESS. MY COMPLAINT IS ON RECORD AT GM'S CORP SERVICE CENTER WITH PHONE NUMBER 866-790-5600 - TICKET #[XXX]. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR
