GM IGNITION SWITCH PROBLEMS/RECALL. ON 07/18/2014 I TOOK MY 2005 CHEVROLET TRAILBLAZER (32,262 MI.) IN FOR SERVICE TO FIX/REPLACE PARTS: FAULTY IGNITION SWITCH. TODAY, 06/02/2017, MY TRAILBLAZER (35,193 MI.) IS STILL HAVING THE SAME PROBLEM. A FAULTY IGNITION SWITCH WHICH IS CAUSING ABS AND PARKING BRAKES LIGHTS TO COME ON AND STAY ON, THE BLOWER FOR AIR/VENT WILL NOT WORK AND SINCE THESE PARTS ARE ALL CONNECTED ELECTRICALLY, I ONCE AGAIN HAVE TO REPLACE THE FAULTY IGNITION SWITCH. I WAS NEVER REIMBURSED FOR THE FIRST RECALL. PLEASE LOOK INTO THIS MATTER. I WOULD HATE TO GET RID OF A PERFECTLY GOOD VEHICLE, THAT HAS HELD UP ALL OF THIS TIME, I ONLY HAVE 35,200 MILES ON THIS 2005 CHEVROLET TRAILBLAZER. WILL THE IGNITION SWITCH KEEP FAILING ON THIS VEHICLE? THANK YOU.

WHEN DRIVING VEHICLE BOTH LEFT AND RIGHT LOW BEAM HEADLIGHTS GO OUT. THE FIRST TIME IT HAPPENED WAS WHEN I WAS DRIVING LONG DISTANCE IN THE DARK. HAD TO DRIVE WITH MY HIGH BEAMS ON FOR THE REST OF THE TRIP. THERE IS NO SPECIFIC TIME FRAME, BUT GENERALLY IT HAPPENS ANYWHERE FROM 10- 30 MINUTES OF DRIVING. I SUSPECT IT IS HEAT RELATED. I HAVE CHANGED THE HEADLIGHT RELAY #46, BIT IT ONLY FIXED THE PROBLEM FOR A WEEK. AGAIN THE LIGHTS WILL GO OUT AFTER DRIVING SEVERAL MINUTES. I NOTICED THERE IS A RECALL FOR A SIMILAR ISSUE ON THE 2006 CHEVY TRAILBLAZER. COULD THIS BE THE SAME PROBLEM WITH MY VEHICLE. THERE ARE ALSO MULTIPLE FORUMS EXPLAINING THE SAME EXACT ISSUE WITH EARLY 2000 MODEL TRAILBLAZERS. THIS ISSUE HAPPENED APPROX 6 MONTHS AGO. LAST WEEK WE RAN INTO ANOTHER PROBLEM. OUR ABS LIGHT COMES ON PERIODICALLY. LIKE THE HEADLIGHTS GOING OUT, THE ABS LIGHT COMES ON AFTER DRIVING THE VEHICLE FOR A CERTAIN AMOUNT OF TIME ANYWHERE FROM 10 MINUTES TO 30 MINUTES. AGAIN, I FEEL IT ELECTRICAL COMPONENTS/WIRING IS OVERHEATING AND CAUSING THESE ISSUES. I FEEL THERE SHOULD BE A SAFETY RECALL FOR THIS THIS ISSUE AS IT IS AFFECTING HUNDREDS OF CUSTOMERS USA WIDE.

WHEN I ACCELERATE FROM 45 TO 60 MILES PER HOUR MY WHOLE TRUCK VIBRATES AND IT FEELS LIKE THE ENGINE IS SEIZING BUT IF I ACCELERATE MORE OR REDUCE MY SPEED IT GOES AWAY. I WAS RESEARCHING ONLINE AND FOUND OUT I WASNT THE ONLY ONE IN THE COUNTRY THAT HAS THIS PROBLEM. I WAS JUST THINKING OF EVERYONE'S SAFETY INCLUDING MY OWN.

2RQ17002 · 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.
