Remedy
Dealers will replace the crankshaft position sensor free of charge. the recall began on december 18, 2007. owners may contact chevrolet at 1-800-630-2438 and GMC at 1-866-996-9463.
Certain cequent 90 degree 7-WAY right angle adaptors sold by distributors in tow packages for aftermarket sales to tow 5TH wheel rv travel trailers. due to incorrect wiring of the harness, the trailer lights may not operate properly.
Risk and remedy
Risk
If the trailer lights are not working properly, a vehicle crash can occur.
Remedy
All of the defective tow packages are still at the distributor level and have not been sold to any consumers.
Certain pickup trucks and sport utility vehicles may experience unwanted antilock brake system (ABS) activation. this condition IS more likely to occur in environmentally corrosive areas. this recall will be launched in the "salt belt" states of connecticut, delaware, illinois, indiana, iowa, maryland, massachusetts, maine, michigan, minnesota, missouri…
Risk and remedy
Risk
This can cause increased stopping distances during low-speed brake applications, which could result in a crash.
Remedy
Dealers are to remove the wheel speed sensor and thoroughly clean the wheel speed sensor mounting surface on the bearing, apply rust inhibitor to the cleaned surface, grease the mounting surface, reinstall the wheel speed sensor, and check the peak-to-peak output voltage to ensure the wheel speed signal IS within specifications. the recall began september 22, 2005. owners may contact chevrolet at 1-800-630-2438 or GMC at 1-866-996-9463.
On certain pickup trucks equipped with manual transmissions and built with either pbr parking brake systems or trw parking brake systems, the parking brake friction linings may wear to an extent where the parking brake can become ineffective in immobilizing a parked vehicle.
Risk and remedy
Risk
If the parking brake does not hold, unintended vehicle movement could occur, which could result in a crash.
Remedy
Dealers will install a low-force spring clip retainer for vehicles equipped with a pbr parking brake system. on vehicles equipped with the trw parking brake system, dealers will install a redesigned parking brake cable assembly. the recall began on july 29, 2005. owners may contact chevrolet at 1-800-630-2438 or GMC at 1-866-996-9463.
Aftermarket pickup truck over-the-rail bedliners manufactured for installation on 1999-2004 chevrolet silverado and GMC sierra pickup trucks. the toggle wing assembly used to attach the bedliner to the truck bed IS not engaging fully in the stake pocket of the pickup truck.
Risk and remedy
Risk
The bedliner can become detached from the pickup while it IS motion, possibly endangering following motorists or pedestrians.
Remedy
Durakon will issue a press release in attempt to notify customers that could have purchased the defective bedliner. if you purchased either a durakon allstar of patriot overrail bedliner since august 1, 2003, for 1999 to 2004 chevrolet silverado or GMC sierra trucks, or purchased one of these pickup trucks with either brand bedliner already installed, you should return to an authorized durakon dealer so that the bedliner can be inspected and, if necessary, repaired with a newly designed toggle wing fastening system, or if required, replaced with a new bedliner free of charge. please call the durakon hotline at 1-800-933-4200 to find the nearest authorized durakon dealer.
On certain pickup trucks and sport utility vehicles, the galvanized steel tailgate support cables that retain the tailgate in the full open (horizontal) position may corrode, weaken, and eventually fracture. if both cables fractured, the tailgate would suddenly drop and strike the top surface of the rear bumper.
Risk and remedy
Risk
Anyone sitting or standing on the horizontal surface of the tailgate when both cables fractured could be injured by falling from the tailgate. on vehicles that have had the bumper removed, the tailgate may drop even lower. additionally, if there IS cargo on the tailgate the cargo may fall off if the support cables fracture.
Remedy
Dealers will replace the cables. interim owner notification began on april 7, 20004. the recall began on september 24, 2004, when replacement parts were available, and will continue through october 29, 2004. owners should contact cadillac at 1-866-982-2339, chevrolet at 1-800-630-2438 or GMC at 1-866-996-9463, or visit www.mygmlink.com, and enter your vehicle identification number.

05068A product safety recall front wheel speed sensor corrosion. my vehicle was serviced for this recall in 2006 which involved removing and cleaning the ABS sensor and reinstalling it. no redesign was created to improve this flawed design. I'm having the same failures described and covered in this recall. while moving at slow speeds in dry conditions ABS kicks in and increases my stopping distance. I hit a parked car in a parking lot due to this defect. my vehicle was in motion at <5MPH on dry pavement when the breaks went into 'ABS mode' and hit a stationary parked car. luckily no one was hurt. when I contacted GMC I was told that this would not be covered under the recall because it was already serviced for this recall in 2006 and that the issue was therefore closed. in my case the original recall was not adequate and my car breaks still failed even though serviced in 2006. I hope this doesn't start to occur with all of the vehicles that were serviced ~10 years ago which IS why I'm filing this complaint. link to recall: http://www-odi.nhtsa.dot.gov/acms/cs/jaxrs/download/doc/acm5671334/rcrit-05v379-9258.pdf

I was traveling on I-95 south in virginia on the hov lanes at about 1:30 pm approaching the route 1 exit. Traffic was dead stopped in front of a moderate flow of traffic and everyone quickly slammed the brakes (including me) to slow and stop to prevent rear ending the stopped cars. traffic was flowing at approximately 75 mph when I slammed my brakes. The brakes grabbed momentarily and then I heard a loud pop and the brake pedal went to the floor; the vehicle brakes were gone. No pressure was at the pedal even as I pumped it. the only way out was to hit the should and berm and take the route 1 exit to coast to a stop; which I did. no fluid loss was evident at the master cylinder reservoir and I couldn't see evidence of a blown line or brake caliper until I got the vehicle home and noticed the metal (steel) brake line between the master cylinder and the anti-lock brake control valve/module was leaking at a pit in the line caused by rust. the point was under the driver side floor pan on the outside of the frame and parallel with the frame. it blew a rusted pitted spot on the line under pressure.. *Js

I was on my way home from an event this past saturday heading to drop off my son. After dropping him off I continued home. I was traveling about 35 mph when the light turned red and I depressed the brake and was terrified when it went down to the floor. Although I have as able to come to a stop without incident I have as still terrified. I am a disabled veteran with a heart condition and could have had a heart attack. I had my truck looked at by my certified mechanic and he told me that my brake line ruptured due to rust and it will cost me around $1000.00 for repairs. I have had many many cars and trucks in my lifetime and never ever experienced any problems of this nature. It seems to me the manufacture would allow for these northern conditions with the parts they use in production. *tr

Experienced complete failure of the braking system. Fortunately the vehicle was only traveling 15mph and in an area that wasn't congested with traffic. I was able to stop by using the roadside berm banking and avoided any further damage. Vehicle was towed to a nearby gm dealership where it was determined that both brake lines had corroded so badly it caused the lines to rupture resulting in an immediate loss of pressure and complete brake failure. Just days earlier I had the brakes serviced at a different gm dealership near my home and there was no mention of this condition nor the previous reports of this problem from other owners as noted on this web site. Even if gm or the nhtsa does not deem this issue frequent enough to issue a tsb, at minimum a service warning/recommendation should be issued to gm dealerships and other registered service providers alerting them to inspect for this condition while servicing the braking systems for these model years. Death or serious injury can and most likely will occur as there are many vehicles from these model years still on the road. *tr

When my issues started, I would fill my gas tank and the gas gauge would plummet to empty. While driving, it would go to full, back to empty or be anywhere in between. At that time, there no no mechanical issues, just the annoying fact that you had no idea how much fuel you actually had. This went on until this spring, when I had the first potentially dangerous incident. I was driving down a county highway at approximately the speed limit and the truck's engine just shut off. No power steering, nothing. It happened just as I was coming to a stop sign thankfully. I was about 50 miles from home and was able to call a friend that manages the collision center of a local car dealership to see about getting a tow or his opinion as to what was wrong. After about ten minutes and after numerous attempts, it restarted. I talked to several mechanics and got the same answer from all of them: the fuel pump and sending unit fail in GMC trucks around the mileage, 95,000 miles, that I currently have on the truck. The gas gauge IS still erratic, I have had two episodes of the vehicle stalling and now the service engine soon light IS coming on and when it IS put on an analyzer it says emissions, but there IS nothing wrong with the emissions system. I have also talked to owners who have had theirs replaced and everyone says to get a factory made pump because the cheap aftermarkets break down even quicker. I googled the information and the problem appears to be widespread. *tr

- Brake line corrosion failure
The Office of Defects Investigation (ODI) received Defect Petition DP10-003 on March 2, 2010, requesting the investigation of model year (MY) 2003 Chevrolet Silverado 2500HD 4WD pickup trucks for corrosion failures of the vehicle brake lines.DP10-003 was granted and on March 30, 2010, Preliminary Evaluation PE10-010…
The Office of Defects Investigation (ODI) received Defect Petition DP10-003 on March 2, 2010, requesting the investigation of model year (MY) 2003 Chevrolet Silverado 2500HD 4WD pickup trucks for corrosion failures of the vehicle brake lines.DP10-003 was granted and on March 30, 2010, Preliminary Evaluation PE10-010 was opened on more than six million model year 1999 through 2003 light trucks and sport utility vehicles manufactured and sold by General Motors Corporation (GM).On July 2, 2010, ODI received GM's response to an information request, which included GM's assessment of the frequency and safety consequences of the alleged defect. GM stated that:(1) the brake system of the subject vehicles is split front/rear and should a brake pipe suddenly fail for any reason, the affected vehicle would be capable of stopping with the pressure supplied by the remaining circuit; (2) the subject vehicles were designed to meet the hydraulic circuit partial failure requirements of Federal Motor Vehicle Safety Standards 105 and 135, Light Vehicle Brake Systems; and (3) should a brake fluid leak occur for any reason, the brake system malfunction indicator lamp (MIL) would illuminate and warn the driver before the brake fluid level was low enough to cause a loss of line pressure.ODI's and GM's analysis indicates that 85 percent of the complaints occurred on vehicles used primarily in States that use salt on the roads during Winter months (Connecticut, Delaware, District of Columbia, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia and Wisconsin).Overall the complaint rates per 100,000 vehicles for Salt Belt States is 43.0 and Non-Salt Belt is 3.0.In approximately 25 percent of the complaints the brake pipe failure occurred suddenly, with no warning (i.e., no MIL, Brake Fluid Loss Warning), and resulted in extended stopping distances.In 30 of these the increase in stopping distance that resulted was a factor in the crash and in 10 others the vehicle was intentionally steered off the road or into another lane of travel in order to avoid a crash.This investigation has been upgraded to an Engineering Analysis (EA11-001) for subject vehicles sold or currently registered in Salt Belt States to further assess the scope, frequency and safety risks associated with sudden failures of corroded brake pipes that can result in decreased brake effectiveness. ODI will continue to gather information on subject vehicles outside the Salt Belt as well.

The office of defects investigation (odi) opened a preliminary evaluation (pe06-016) on may 4, 2006 based on eleven vehicle owner questionnaires (voqs) and early warning (ewr) data alleging sudden engine shutdown while driving as a result of crank position sensor failures in my 2001-2002 general motors c/k platform vehicles equipped with 8.1L engines.in response to an information request letter sent by odi, general motors (gm) provided owner complaint information, field reports and warranty claim data based on a population of 108,338 vehicles. The data was categorized by engine stalls while driving, engine stalls with an unknown driving condition, no start conditions and claims where it was indeterminate if an engine stall occurred while driving.general motor's response included 1,213 owner complaints and field reports of which 289 were categorized as engine stalls while driving allegedly caused by crank position sensor failures. General motors also submitted warranty claims from its regular warranty (5 years/50,000 miles) and from its extended warranty database. From the regular warranty database there were 3,140 claims of crank position sensor replacement of which 147 claims were from consumers alleging engine stall while driving.gm stated that 2,841 of the claims were indeterminate if an engine stall occurred while driving.from its extended warranty database, gm submitted 1,561 claims of crank position sensor failure that it also stated were indeterminate as to whether an engine stall occurred while driving.in total, gm reports 4,701 claims of crank position sensor failure combining regular warranty and extended warranty.similar to gm's statistical analysis, odi's analysis showed that the failure rate for warranty claims of engine stall while driving at three years in service IS low (less than 1%).however, further analysis determined that the my 2001 vehicle build period from may 2000 through october 2000 had significantly higher (more than four times) crank position failure rates in both consumer complaint data and warranty claim data than in the build period from november 2000 through july 2001.adding the claims of known engine stall while driving and claims where engine stall was indeterminate, the failure rate at three years in service for this population IS over 6%.AN engineering analysis (ea06-016) has been opened to further assess the frequency and potential safety consequences associated with the alleged defect in vehicles built from may 2000 through october 2000.
- Parking brake failure
Odi's review of complaint data received since the close of ea04-011 revealed no indication that the investigation should be re-opened.more details can be found in the federal register notice enclosed in the dp05-009 public file.odi reserves the right to reopen the investigation in the future should conditions warrant.

In a letter dated august 29, 2005, gm notified odi that it was recalling certain model year 1999 through 2002 c/k pickup trucks and sport utility vehicles to correct a problem with anti-lock brake system (ABS) wheel speed sensor corrosion that may result in unwanted ABS activation and extended stopping distances during low-speed braking (recall 05v-379).gm's recall covers approximately 804,000 vehicles currently registered in the following 14 salt-belt states:connecticut, illinois, indiana, massachusetts, maine, michigan, new hampshire, new jersey, new york, ohio, pennsylvania, rhode island, vermont, and west virginia.the recall procedure will involve removing the sensor, cleaning the mounting surface, applying a rust inhibitor (zinc-x) to the surface, and reinstalling the sensor.if necessary, the sensor will be replaced. The population and failure report data given in this resume are for the full region that has been considered by odi as the salt-belt.that includes delaware, iowa, maryland, minnesota, missouri, wisconsin and the district of columbia in addition to the 14 states included in 05v-379.the states covered by gm's recall have the highest incident rates for the subject condition, accounting for 91% of the incidents, but only 24% of subject vehicle sales in the united states.odi's analysis determined that 840 of the complaints, 244 of the crashes, and 16 of the injuries identified in this investigation occurred in those states.the resulting incident and crash rates are 96.2 and 28.0 per 100,000 vehicles respectively (note:rates are based on vehicle sales, not registered vehicles). The corresponding numbers in the excluded portions of the salt-belt are 399,000 vehicles, 81 incidents (20.3 per 100,000 vehicles), 3 crashes, and no injuries.the statistics in the remaining 30 states are 2,406,000 vehicles, 168 incidents (7.0 per 100,000 vehicles), 31 crashes, and one injury.gm and odi are continuing to monitor the problem experience in states that are not included in the recall.gm will provide odi with updated complaint, field report, and warranty data in november 2005.odi and gm will review that data and assess the appropriateness of the current scope of the recall at that time.

Odi opened pe03-057 to assess parking brake ineffectiveness in the subject vehicles.these vehicles are equipped with four wheel disc brakes that incorporate a single-shoe drum-in-hat parking brake independent of the service brakes.complaint and warranty data indicate that the parking brake linings tend to wear out early in the life of the vehicle (at an average of 24 months in service), reducing the parking brake system's torque below that needed to immobilize the vehicle.gm has attributed this accelerated wear to foreign material intrusion and a failure of the brake shoe to properly self-center within its brake drum.effective with the start of my 2003 production, a newer reduced force hold-down clip was introduced to facilitate brake shoe disengagement from the drum surface.this part IS also available at the service level for the my 1999-2002 vehicles.gm has indicated that the paking brake IS intended to operate in conjunction with the transmission to immobilze parked vehicles, and that in many cases, accelerated parking brake lining wear IS caused by rough use, vehicle modifications, and driving with the parking engaged. Odi has upgraded the preliminary evaluation to an engineering analysis to gather further information concerning parking brake usage factors and the circumstances surrounding the seventeen reported vehicle crashes.

This investigation involves the general motors corporation (gm)throttle body (tb) utilized in model year (my) 1999-2002 silverado, sierra, tahoe, suburban, avalanche and yukon (subject vehicle(s)) with 4.8L, 5.3L, and 6.0L engines. The tb valve may intermittently stick in a closed position.in such a situation, an operator may apply additional accelerator pedal force to increase engine speed.the application of additional accelerator pedal force, to open a stuck throttle valve, may open the throttle valve more than intended and, in turn, accelerate the engine and vehicle more than intended and reasonably expected by the driver.on august 1, 2002, the office of defects investigation (odi), of the national highway traffic safety administration (nhtsa), opened this engineering analysis.the investigation revealed that two factors may cause the defect: 1) tb manufacturing process problems; and 2) accumulation of deposits (a pcv system by-product) on or around the tb throttle valve and bore.odi concludes that the tb performs in a defective manner after analyzing gm?s data submissions, and test data collected by the vehicle research and test center (vrtc).fifty-nine crashes are alleged to have occurred as a result of gm?s tb defect.the majority of the crashes involve a single vehicle, engaging in a close quarter vehicle maneuver (or low speed), and causing only minor property damage.four out of the fifty-nine crashes involve injury, and those injuries were minor.although gm?s tb IS defective, based on the evidence gathered, odi has found that the accelerator pedal force required to open a stuck throttle valve IS negligible, and the throttle valve does not stick in the open position.therefore this engineering analysis (ea02-015) will be closed at this time.the closing of this investigation does not constitute a finding by nhtsa that a safety-related defect does not exist.for a detailed discussion of the tb component and testing, please see the attached report.
