Rusty brake lines lost brakes, think that a vehical should go 10 years without brake lines rusting away I was lucky when they broke I was home but just got back from another state and was at highway speeds.
- Fuel/propulsion system
The primer pump housing develops a small leak around a electrical connection. this could lead to a fire as fuel drops on the engine. gm IS aware of problem it has been on going for several years. it only occurs when vehicle IS running. note-no fire has happen to my vehicle, nor do I know of a fire occurring. I just believe this IS unsafe. the only way to correct the problem IS to replace primer pump housing.

Why IS gm recall 14121 limited to new vehicles? It has been a recurrent, common problem since long before 2000. Long before I bought my 2007 GMC sierra classic 2500hd which IS on the third repair. I just replaced a transmission cooler line in my driveway. Today. which IS steadily eroding by way of continuous transmission cooler leaks. It continuously coats the underside of vehicle, reducing life of belts and hoses. Gm dealers feel its not covered by 5/100k powertrain warranty, or 36K bumper-bumper warranty because it's a long time gm problem as well as warranties in general. *tr

As I was traveling about 35mph approaching a red stoplight I proceeded to press the brake pedal all the way to the floor, with no braking of the vehicle. luckily I was able to quickly shift the vehicle into neutral and engage the emergency brake and avoid collision. after further inspection I found the hard brake line running to the front left wheel had ruptured causing the loss of brake fluid. the line ruptured in an area where it was severely corroded and upon inspection, the other hard brake lines of the system looked severely corroded also. all will have to be replaced! this failure could have had a very bad consequences at a higher speed, closer proximity to other vehicles, or with a less experienced driver! *tr

2007 GMC sierra classic with approximately 54,000 miles was being driven into a garage to have wheels balanced. As the technician applied the brakes entering the garage, the brake lines on the front drivers side of the vehicle ruptured and the brake peddle went to the floor. Brake fluid poured out onto the floor and the brakes became completely unusable. If this had happened a few hours earlier in the day as I was traveling on steep mountain highways in west virginia I have no doubt an accident and probable fatality would have occurred. All recommended maintenance had been performed at the gm dealer where the truck was purchased and no warnings from gm were given that the brake lines were showing any signs of wear or that a complete brake failure like this could happen. *tr

I was driving my 2007 GMC siearra classic 2500hd wt and my brake line failed. I went threw the stop sign out onto a main road and just missed getting t-boned by a tractor trailer. I had no brakes at all. My brakes are all up to date. Brand new brake pads and rotors. I read tons of complaints online of people with the same problem with gm vehicles brake lines rusting out prematurely. My truck only has 32,164 miles on it and IS well taken care of. I get compliments on my truck everywhere I go. I got nowhere with gm corporate or marty's GMC in kingston,ma where I bought this truck brand new. They all pretended they do not know anything about these brake lines failing. They now use a different coated brake line to replace the cheaply made brake lines at the customers expense. Please make gm do a safety recall on these failing rusting brake lines before someone gets killed. I was almost not here to tell my story.

While driving the truck on a residential street, the brakes completely failed when I depressed the brake pedal (it went to the floor) and attempted to stop. I lost all normal braking ability and had to stop by down shifting and applying the emergency brakes. when I got the truck stopped and got out, I found that the brake fluid was pouring out onto the ground. A qualified mechanic inspected the truck and found that the brake lines were rusted through and had ruptured. he went on to tell me that this problem IS a frequently occurring know problem with GMC pickup trucks and that GMC refuses to acknowledge the issue. *tr

Hvac system became operational with the ignition turned off for an unknown period of time while the truck was parked in the garage. Relay resistor module overheated causing melting of the resistor and circuit board. Truck cabin and vicinity around the truck had a strong smell of burning plastic. Truck cabin filled with smoke. was only able to turn off the hvac system and stop the burning by disconnecting the wiring harness. Dealer had to replace the blower motor, resistor, module connector and relay. burning could have caused the entire vehicle to catch fire causing significant damage to other vehicles parked nearby and the house in which the garage was attached. issue was identical to scenario described in transport canada recall #2011074. *tr

In a letter dated august 27, 2008, general motors corp. (Gm) notified nhtsa that it will conduct a safety recall (nhtsa recall number 08v-441) to address a safety relateddefect that can result in engine compartment fire in approximately 850,000 vehicles equipped with a heated windshield washer fluid option.the subject vehicles of this investigation comprise over three-quarters of the recall population. According to gm, a short circuit on the printed circuit board for the windshield washer fluid heater module may overheat the control-circuit ground wire. This may cause other electrical features to malfunction, create an odor or cause smoke and in rare cases it may cause a fire.as a remedy, gm dealers will install a wire harness with an in-line fuse. In addition to the subject vehicles, several other gm models with the heated windshield washer fluid option are included in recall 08v-441: my 2006-2008 buick lucerne (manufactured august 2005 through november 2007); my 2008 buick enclave (manufactured february 2007 through april 2007); my 2006-2008 cadillac DTS (manufactured may 2007 through november 2007); my 2007-2008 saturn outlook (manufactured august 2006 through april 2007); and my 2007-2008 GMC acadia (manufactured august 2006 through april 2007) vehicles.gm IS instructing owners to take their vehicle to a dealer for service if they experience symptoms of windshield washer heater module short circuits. Gm's recall resolves the safety defect concerns pursued by this investigation.this engineering analysis IS closed.

While in the United States they are unable to receive Turn-by-Turn directions. Due to the existing cellular provider not having roaming agreements in areas outside of Canada to support transmitting of the packet data required for Turn-By-Turn feature to operate. The customer has 3 options while traveling through the United Sates. First if the vehicle is equipped with a navigation radio they can request a "Destination Download" to the vehicle. Second if the customer uses the OnStar RemoteLink app they can send the directions to the vehicle. The third option would be to have the vehicle loaded with a "500 phone number" The customer will no longer be able to use their Hands Free Calling minutes when the new 500 phone number is loaded.

- 10114354This Preliminary Information communication provides information to the technician that some vehicles may have a Service Engine Soon lamp, engine misfire on cylinder 1, 4, 6, or 7 and/or tick noise. Technician will follow service information diagnosis first. If service information diagnosis does not isolate the cause of this concern perform a cylinder deactivation active fuel management system compression test in service information. If the running compression of the misfiring cylinder stays below 25 Pounds per Square Inch regardless of the active fuel management solenoid being commanded on or off, an active fuel management lifter is mechanically collapsed/stuck or unlocking as soon as the engine is started. Replace all active fuel management lifters, and all plastic lifter guides. Also perform the cylinder deactivation active fuel management Valve Lifter Oil Manifold Diagnosis and Testing in Service Information. If it isolates a concern with the Valve Lifter Oil Manifold, replace it and reevaluate the concern. The active fuel management lifters can also be monitored for proper operation by carefully inspecting the cylinder 1, 4, 6, and 7 rockers and valves while cranking or briefly and safely running the engine with the valve covers removed. If the valve or valves of an active fuel management cylinder stop moving while doing this test, the active fuel management lifter is causing the concern. For 2008-2009 Full Size Truck/SUV or a 2007-2009 Chevrolet Tahoe with the Police Package reprogram the Engine Control Module. On the 2008-2009 Pontiac G8, 2010-2011 Camaro, and 2007-2010 Full Size Trucks with active fuel management, also determine if the active fuel management pressure relief valve shield that is listed in the latest version of 10-06-01-008 has ever been installed.
