2008 PONTIAC GRAND PRIX ENGINE WILL AUTOMATICALLY STOP RUNNING WHEN DRIVING. THIS SHUTS DOWN THE POWER STEERING, BRAKES, ETC. THIS HAS HAPPENED ABOUT A DOZEN TIMES OVER THE LAST YEAR. ALL BUT TWO TIMES WHEN THIS HAPPENED, WE WERE ABLE TO PUT THE CAR IN NEUTRAL AND RESTART THE CAR. TWO OF THE TIMES, THE CAR DID NOT WANT TO START - CAR WOULD CRANK BUT NOT START. EVENTUALLY WE WERE ABLE TO GET THE CAR STATED. OVER THE PAST YEAR THIS HAPPENED WHEN WE WERE DRIVING IN A CITY AT APPROXIMATE 30 MPH, COASTING DOWN A HILL, OR STOPPED AT A STOP SIGN. HOWEVER, WE DID NOT TAKE THIS CAR ON THE HIGHWAY VERY OFTEN SO WE HAVE NOT HAD THIS ISSUE HAPPEN ON THE HIGHWAY. SO FAR, WE HAVE BEEN LUCKY AND HAD NO ACCIDENTS WITH THE CAR. SYMPTOM'S ARE VERY SIMILAR TO THE GM IGNITION SWITCH RECALL. WE TOOK THE CAR TO TWO REPAIR PLACES AND THE DIAGNOSTICS WOULD NOT SHOW ANYTHING. WE RECENTLY TOOK THE CAR TO A GM DEALER AND THEY RAN A DIAGNOSTICS AND THEY DETERMINED CRANKSHAFT POSITION SENSOR CODE P0335. THEY REPLACED 10456161 SENSOR AND EMISSIONS SYSTEM REPAIR. THEY ARE NOT 100% SURE THAT THIS WILL FIX THE PROBLEM. THIS IS A VERY DANGEROUS SITUATION AND WE DO NOT ALLOW OUR KIDS TO DRIVE THE CAR FOR FEAR OF THEM BEING KILLED IN AN ACCIDENT. *TR

THE ENGINE COOLANT SYSTEM CLOGGED UP MY THERMOSTAT AND COOLANT TURNED TO A BROWN CONSISTENCY AND THICKENED LIKE MUD. MECHANIC STATED THAT THE COOLANT, DREX, CAN HAVE NO FLUIDS ADDED, AND NO WATER UNLESS IT IS DISTILLED. I DID NOT ADD ANY COOLANT OR WATER AND RECEIVED NO COOLANT LOW WARNING. I PREVIOUSLY HAD CAR WORKED ON ONE YEAR AGO FOR THE SAME PROBLEM. I WANT ALL VEHICLES EVERYWHERE WITH DREX FOR COOLANT RECALLED AND REPAIRED. DREX IN THE COOLING SYSTEM IS A DESIGN FLAW. I THINK EVENTUALLY IN A COOLANT SYSTEM SOME MOISTURE FORMS FROM THE HEATING UP AND COOLING DOWN PROCESS OF A RADIATOR AND CONDENSATION FORMS. THIS WOULD THEN GUM UP AND RUIN A CARS COOLING SYSTEM AND COULD CAUSE THE VEHICLE TO OVERHEAT AND POSSIBLE THE ENGINE TO BE RUINED. THIS IS THE SECOND CAR WHERE I HAD TO DO REPAIRS BECAUSE THE DREX CLOGGED UP THE RADIATOR AND MADE MY ENGINE OVERHEAT. *TR

Official recalls

14V400000 · Electrical System:ignition

Jul 3, 2014

This defect can affect the safe operation of the airbag system. Until this recall is performed, customers should remove all items from their key rings, leaving only the ignition key. The key fob (if applicable), should also be removed from the key ring. General Motors LLC (GM) notified the agency on July 3, 2014, that they are recalling 5,877,718 model year 2000-2005 Chevrolet Impala and Monte Carlo, 1997-2003 Chevrolet Malibu, 2004-2005 Malibu Classic, 1999-2004 Oldsmobile Alero, 1998-2002 Oldsmobile Intrigue, 1999-2005 Pontiac Grand Am and 2004-2008 Pontiac Grand Prix vehicles. In these models, the weight on the key ring and/or road conditions or some other jarring event may cause the ignition switch to move out of the run position, turning off the engine.

Consequence & remedy

Consequence: If the key is not in the run position, the air bags may not deploy if the vehicle is involved in a crash, increasing the risk of injury.

Remedy: GM will notify owners, and dealers will install two key rings and an insert in the key slot or a cover over the key head on all ignition keys, free of charge. The recall began on September 9, 2014. GM's number for this recall is 14350.

RQ17002 · Loss Of Headlights

Opened Apr 24, 2017 · Closed Mar 29, 2021

Status: closed (inferred from source dates) · Exterior Lighting:headlights

The subject vehicles are model year (MY) 2002-2009 Chevrolet Trailblazer, GMC Envoy, 2004-2007 Buick Rainier, 2003-2008 Isuzu Ascender, 2005-2009 Saab 9-7X, 2002-2004 Oldsmobile Bravada, 2003-2006 Chevrolet SSR, 2005-2009 Buick Lacrosse, and 2006-2008 Pontiac Grand Prix. This scope includes the Trailblazer/Envoy variants: 2002-2006 Envoy XL/Trailblazer EXT and 2004-2005 Envoy XUV. The original scope of this investigation was expanded to include all vehicles equipped with the subject Headlight Driver Module (HDM). The focus of the investigation was to determine whether actions performed by General Motors adequately addressed any unreasonable risk to motor vehicle safety in the subject vehicles concerning the headlights and the HDM that controls them.Under normal electrical load and environmental conditions, the HDM can overheat inside the Underhood Electrical Center (UEC). This can cause the module to fail and result in a simultaneous loss of both low beam headlights and both daytime running lights (DRLs), often with no warning or prior detectability to the driver. This failure can be intermittent or permanent. No other exterior lights are affected. High beams, turn signals, brake lights, and reverse lights are still operational.General Motors addressed this issue with 2 recalls (14V755 & 15V519) and a special coverage program (N172091910). In view of the recalls and special coverage program implemented by GM and the vehicle high beams continuing to operate, ODI has tentatively concluded that the actions taken by GM mitigate any unreasonable risk to safety posed by HDM failure in the subject vehicles.Accordingly, the investigation is closed. The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist. The agency reserves the right to take additional action if warranted by new circumstances.The ODI reports cited above are available for review online at NHTSA.gov under the identification numbers in the attached document.
