WHILE DRIVING ON A CITY STREET THE CAR STARTED LUGGING AND NOT DRIVING SMOOTHLY. WHEN I NEEDED TO BRAKE SHORTLY AFTER THIS HAPPENED THE BRAKE PEDAL WENT TO THE FLOOR AND I HAD NO BRAKES. I PUMPED THE BRAKES AND WAS ABLE TO STOP WITHOUT HITTING ANY ONE. I CONTINUED ABOUT 5 MILES CONTINUALLY PUMPING THE BRAKES NOT KNOWING IF THEY WOULD WORK .DURING THIS TIME THE PEDAL WOULD SOMETIMES GO TO THE FLOOR AND OTHER TIMES ALMOST GO TO THE FLOOR. THEN AS SUDDENLY AS IT STARTED IT STOPPED. BRAKES WERE BACK TO NORMAL. THIS HAPPENED PREVIOUSLY AND THE GMC MECHANIC FOUND NOTHING WRONG. SO I'M PUT BACK ON THE STREET RISKING MY LIFE AND SOMEONE ELSE'S BECAUSE THE MECHANIC SAID "IT SOMETIMES HAPPENS". THAT'S NOT ACCEPTABLE!

HELLO, FIRST OFF, THIS IS NOT A VEHICLE ISSUE OR COMPLAINT. THIS IS AN AFTER MARKET COMPONENT ISSUE REGARDING BOSCH EVOLUTION WIPER BLADES. I PURCHASED BOSCH EVOLUTION ALL SEASON WIPERS FOR MY 2004 ENVOY FROM WOOT.COM AND INSTALLED THEM LAST SUMMER. THEY WORKED FINE UNTIL LAST MONTH WHEN WINTER WEATHER HIT HERE IN NEW YORK STATE. IN COLD WINTER CONDITIONS THREE THINGS HAVE OCCURRED: 1.THE WIPER LATCHES ARE LIFTING UP (RELEASING) ALLOWING THE WIPERS TO NO LONGER BE SECURED TO THE WIPER ARM. MY PASSENGER SIDE WIPER HAS ACTUALLY SEPARATED FROM THE WIPER ARM TWICE SO FAR, AND I HAVE HAD TO PULL OVER TO RETRIEVE THE WIPER FROM THE STREET WHILE AVOIDING TRAFFIC. 2.AND, IN COLD WINTER CONDITIONS THE WIPERS BLADES ARE TAKING A 'SET' THUS SCRAPING THE WINDOW LOUDLY IN ONE DIRECTION INSTEAD OF WIPING THE GLASS IN BOTH DIRECTIONS. 3.ALSO, THE COLD WEATHER IS MAKING THE WIPER BLADES FORM INTO A CURVED SHAPE AWAY FROM THE GLASS, INSTEAD OF BEING FLAT ON THE GLASS. THIS PREVENTS THE WIPER BLADE FROM CONTACTING MOST OF THE WINDSHIELD. I COULD NOT SEE WHERE I WAS GOING BECAUSE THE WIPERS ONLY CLEARED THE WINDOW AT THE TOP AND BOTTOM EDGES BECAUSE ONLY THE ENDS OF THE WIPER BLADE WERE MAKING CONTACT WITH THE WINDSHIELD. I BELIEVE THIS IS A MANUFACTURING DEFECT AND MORE IMPORTANTLY A SERIOUS SAFETY ISSUE. I CONTACTED BOSCH AUTOMOTIVE AND THEY REPLIED THEY ONLY HAVE A 30 DAY WARRANTY ON WIPERS AND I SHOULD CONTACT THE SELLER. BECAUSE OF BOSCH'S I DON'T CARE ATTITUDE I AM CONTACTING THE NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION (NHTSA) REGARDING THIS SERIOUS SAFETY ISSUE. SORRY TO BOTHER YOU WITH THIS ISSUE AND I LOOK FORWARD TO YOUR RESPONSE. THANK YOU FOR YOUR TIME, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

ON CERTAIN TRUCKS AND SPORT UTILITY VEHICLES, THE DRIVER WISHING TO SIGNAL A TURN BY MOVING THE DIRECTIONAL SIGNAL LEVER, (UP OR DOWN) MAY CAUSE THE FRONT MARKER/TURN LIGHTS AND REAR TURN LIGHTS TO FLASH IN A MANNER SIMILAR TO HAZARD WARNING, RATHER THAN FLASHING ON THE DESIRED SIDE ONLY.
Consequence & remedy
Consequence: THE DRIVER MAY NOT BE ABLE TO CLEARLY SIGNAL THEIR INTENTIONS TO TURN, CHANGE TRAVEL LANES, OR POTENTIALLY WARN OTHERS OF AN IMPAIRED VEHICLE OPERATING CONDITION INCREASING THE RISK OF A CRASH.
Remedy: DEALERS WILL REPLACE THE SUSPECT FLASHER MODULES WITH A NEW FLASHER MODULE DESIGNED WITH SEALED RELAYS AND MORE DURABLE CONTACT MATERIAL INSIDE OF THE RELAYS FREE OF CHARGE. THE RECALL BEGAN ON AUGUST 4, 2005. ISUZU BEGAN MAILING OWNER LETTERS ON AUGUST 4, 2005. OWNERS MAY CONTACT CHEVROLET AT 1-800-630-2438, GMC AT 1-866-996-9463, ISUZU AT 1-800-255-6727, BUICK AT 1-866-608-8080, AND OLDSMOBILE AT 1-800-630-6537.

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.
DURING THE COURSE OF THIS EA INVESTIGATION, ODI OBSERVED THAT THE MAJORITY OF THE COMPLAINTS (88%) AND WARRANTY CLAIMS (94%) WERE REPORTED FOR VEHICLES THAT ARE REGISTERED FOR USE IN THE SALT BELT REGION OF THE US.THIS AREA INCLUDES 20 STATES IN THE NORTHEAST, MID ATLANTIC AND THE MIDWEST REGIONS AND THE DISTRICT OF COLUMBIA.CONSUMERS IN THE SALT BELT REGION REPORTED TO ODI THAT THEY COULD SMELL FUEL VAPORS IN THEIR VEHICLES WHILE DRIVING.UPON FURTHER EXAMINATION OF THEIR VEHICLES, THEY DISCOVERED THAT FUEL VAPORS WERE COMING OUT OF THE TOP OF THE FUEL TANK. THIS CONDITION IS CAUSED BY CORROSION OF THE RETURN AND SENDER LINES OF THE FUEL PUMP MODULE.WATER AND ROAD SALT COLLECT ON TOP OF THE FUEL PUMP LEADING TO SMALL PINHOLES APPEARING ON THE FUEL LINES.FUEL MAY LEAK AND COLLECT ON TOP OF THE MODULE AND/OR SPILL ONTO THE GROUND.THE DATA EVALUATED UNDER THIS INVESTIGATION REFLECT A RELATIVELY LOW FREQUENCY OF OCCURRENCE THAT LARGELY ARISES IN SALT BELT STATES.GM HAS EXTENDED THE WARRANTY ON THE SUBJECT COMPONENT TO TEN YEARS OR 120,000 MILES.FURTHER USE OF AGENCY RESOURCES DOES NOT APPEAR TO BE WARRANTED AT THIS TIME; ACCORDINGLY, THIS INVESTIGATION IS CLOSED.THE CLOSING OF THIS INVESTIGATION DOES NOT CONSTITUTE A FINDING BY NHTSA THAT NO SAFETY-RELATED DEFECT EXISTS.THE AGENCY RESERVES THE RIGHT TO TAKE FURTHER ACTION IF WARRANTED BY THE CIRCUMSTANCES.FOR ADDITIONAL INFORMATION SELECT DOCUMENT SEARCH.
BY LETTER DATED APRIL 29, 2005, GM NOTIFIED THE AGENCY THAT IT IS CONDUCTING ASAFETY RECALL ( NHTSA RECALL NO. 05V198 ) INVOLVING CERTAIN MODEL YEARS (MY) 2003-2004 ISUZU ASCENDER, CHEVROLET TRAILBLAZER, GMC ENVOY, OLDSMOBILE BRAVADA AND MY 2004 BUICK RAINER VEHICLES.THE RECALL APPLIES TO VEHICLES BUILT FROM APRIL 2003 THROUGH NOVEMBER 2003 FOR A TOTAL VEHICLE POPULATION OF 286,478.GM REPORTS THE DIRECTIONAL/HAZARD SIGNALS FAILURE IS DUE TO STICKING CONTACTS ON ROUTING RELAYS IN THE FLASHER MODULE.GM WILL REPLACE THE FLASHER MODULE ON ALL INVOLVED VEHICLES.BASED ON GM'S SAFETY RECALL ACTION, THIS INVESTIGATION IS CLOSED.
