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.
Certain trucks and sport utility vehicles were built with fuel module reservoir assemblies that contain fuel pump wires connectors may overheat under certain operating conditions.
Risk and remedy
Risk
If the ignition circuit wire IS exposed, the fuel pump fuse will blow, disabling the fuel pump and causing an engine stall or no-start condition. if sufficient heat IS conducted to the pass-through connector, a hole in the connector may result, which may cause a 'service engine soon' light to be illuminated during the emission system diagnostic routine. fuel vapor and in some cases liquid fuel may leak out of the fuel tank through the hole in the connector body. fuel leakage, in the presence of an ignition source, could result in a fire. also if the ignition circuit or ground wire IS exposed and shorts to the fuel level sender card wires, inaccurate fuel level readings may result.
Remedy
Dealers will remove the fuel tank, and remove the module reservoir assemblies from the tank, and install a new service kit free of charge. an interim letter to owners was mailed on may 25, 2005. the owners were re-notified on october 19, 2005, since parts are now availabe. owners may contact chevrolet at 1-800-630-2438 and GMC at 1-866-996-9463.
Vehicle description: pickup and utility trucks. some of these vehicles have an internal component in the outboard seat belt retractors for the 2ND and 3RD row of seats that could be cracked. with repeated actuation of the locking mechanism, the crack could spread to the point such that the seat belt would no longer lock.
Risk and remedy
Risk
In a crash, increased occupant injury could result from the no-lock condition.
Remedy
Dealers will inspect the outboard seat belts for specific lot numbers and replace the belts if necessary. gm IS enclosing an inspection procedure for the owners to use or they can have their dealers do the inspections. owner notification began july 2, 2001. owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact chevrolet at 1-800-222-1020 or GMC at 1-800-462-8782.
Vehicle description: light duty pickup trucks and sport utility vehicles. some of these vehicles have loose or missing rear wheelhouse plugs. under certain vehicle operating conditions, exhaust gases can flow forward and accumulate in the rear wheelhouse.
Risk and remedy
Risk
These gases could flow into the passenger compartment if the plug IS missing or loose and could cause possible illness, unconsciousness, or death.
Remedy
Dealers will inspect the vehicle for loose or missing wheelhouse plugs and install new plugs if necessary.

The ABS system in this vehicle and many other similar GM vehicles of this year have abs pumps that malfunction and/or randomly stop working just to begin working later. My vehicle currently has the abs fuse removed because whenever it’s in the abs pump runs continuously even when the vehicle is off. The vehicle I own is in good shape with only 80,000 miles. similar gm vehicles of this age with more miles have even more issues specially with the abs system it’s worse in vehicles that also come equipped with traction control.

While driving to work in spring 2018, I approached traffic light, depressed brake, which went to floor and had to use parking break to stop. Had vehicle towed to replace front brake lines. Then, 6-8 months later, while driving, came to another stop light, depressed brakes and could not stop until I used parking/emergency brake. had yukon XL towed to repair shop and had rear brake lines replaced in fall, 2018. Since then, brake lights and ABS lights come on and stay on, whereas other times when starting and driving, brake & ABS lights come on and then go off while driving. Braking has always seemed to be insufficient.

I was traveling approximately 40 mph on a 4 lane street. as I approached a stop light, the light changed from green to red. I applied the brakes and they did not work. I drove right through the intersection and avoided a collision with 2 other vehicles. I was going downhill and picking up speed as I approached the next intersection. the light changed to red and by this time I was going approximately 50 mph. as 2 cars went across in front of me from opposite directions, I was somehow able to drive between them. I was eventually able to shift into neutral and drove approximately 1/2 mile until I was able to turn off of the main road and into a parking lot. I ended up having to drive around the parking lot until I was able to stop. my 15 year old son and I were extremely shaken and very fortunate to have avoided an accident and serious injury or death. we had the vehicle towed and we were told that all of the brakes lines were completely corroded and there was nothing left of them. after a $160 towing bill and a $1,180 repair bill, we have discovered that this IS a recurring problem with the 2001 GMC yukon. the dealership had 2 similar vehicles in their shop that day that had the same problem general motors needs to step up and admit that they made a huge mistake with these brake lines. This could have had a different outcome. my son and I could have been killed and/or another innocent person could have also been killed. my son says he will never ride in this vehicle again. please do something about this situation before somebody dies, as a result of these cheap steel brake lines that corrode, especially in states that use salt on their roads during the winter months. *tr

Our dashboard ABS indicator light came on. when we shut the vehicle off, a buzzing motor sound still kept running. we unplugged the battery so it would not run down. we looked on the internet and found a ton of other people have had the same incidents. we noticed that many of the people who experienced the exact problems we were having, also had brake issues while driving. we reconnected our battery, disconnected the ABS module and the motor sound stopped, but now we don't have the ABS system activated. IS there a recall for this? it seems as though it IS a recurring problem for many people and because it involves the brake system it seems very dangerous. According to other people it IS very expensive to repair as well (approx. $1500.00). has GMC addressed this? We have a suburban yukon XL, 2001. *tr

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.

In a letter dated april 14, 2005, general motors (gm) notified odi that it had identified a defect related to motor vehicle safety in approximately 316,508 model year (my) 2000-01 1500 series chevrolet suburban and GMC yukon XL vehicles (recall 05v-155).gm determined that some of these vehicles were equipped with fuel module reservoir assemblies (mras) that contain fuel pump wires and/or connectors that may overheat under certain operating conditions.according to gm, fuel pump wires that overheat may result in one or more conditions that present risks to motor vehicle safety:(1) fuel leakage from the mra pass-through connector if the overheating produces a hole in the plastic connector; (2) engine stall if wiring exposed by the overheating shorts to ground and causes the fuel pump fuse to blow; or (3) inaccurate fuel level readings if overheated wiring IS shorted to the fuel level sender card.gm's analysis identified the cause of the overheated wiring as a high-resistance condition in the mra connector contacts due to fretting corrosion that may develop over time.gm determined that the corrosion IS caused by movement between the contact surfaces and that such movement IS primarily influenced by chassis and fuel tank virbration characteristics.gm's testing found that the fuel tank vibration characteristics of the recalled my 2000-01 1500-series vehicles were significantly greater than in other gm vehicles equipped with the same mra connectors.these vehicles had the highest rate of related fuel leak and stall complaints; and a recent survey conducted by gm found evidence of mra wiring over-heating in almost one-third of the 1500-series vehicles inspected. Other vehicles equipped with the subject mra connector and evaluated during this investigation include approximately 33,000 my 2000-01 2500-series sububran and yukon XL vehicles, which fall within the scope of ea04-026, and peer populations of short wheelbase yukon and tahoe utility vehicles and full-size silverado and sierra pickup trucks. These vehicles are not included in recall 05v-155 for the following reasons:(1) these vehicles are equipped with fuel tanks with significantly less vibration at the mra interface than the recalled vehicles; (2) the potential for fuel leakage IS substantially lower in the pickup trucks and short-wheelbase utility vehicles due to differences in fuel tank configuration and no incidents of fuel leakage due to overheated wiring were verified in these vehicles; (3) there there have been only three potentially related complaints of fuel leakage associated with the overheated wiring condition in the 2500-series long-wheelbase utility vehicles; and (4) no evidence of overheated wiring was found in the 2500-series suburban and yukon XL vehicles and pickup trucks inspected by gm in its vehicle survey efforts and the rate found in the short-wheelbase utilities was lower than the recalled vehicles by an order of magnitude. Odi will continue to monitor the experience in the 2500 series my 2000-01 long-wheelbase utility vehicles.the closing of this investigation does not constitute a finding by nhtsa that no safety-related defect exists for the 2500 series vehicles.the agency reserves the right to take further action if warranted by a change in circumstances.
- Overheated fuel pump wiring

The fuel pump wiring and connector may overheat and melt a hole in the top of the fuel pump module.possible consequences include fuel tank leakage and engine stall with no restart.fourteen of the 20 complaints to odi allege fuel tank leakage, including one that reported that a fire department was called to the scene after a pool of gasoline was discovered beneath the vehicle.most of the odi complaints report incidents that occurred within the past year. According to gm, fuel leakage can occur in the subject vehicles if the heat IS sufficient to melt a hole in the plastic connector large enough for liquid fuel to flow through.on-board emissions diagnostics may detect holes that are approximately 0.040 inches or more and set a service engine soon warning light.the connector position in the subject vehicles IS below the fuel level when the tank IS full.while gm does not know how much fuel could leak from a tank with a melted fuel pump connector, several consumers have reported significant leak events.engine stall can occur IF:(1) a short occurs in the pump wiring (bare wire exposed by melted insulation shorts against a ground or ground wire) and the fuel pump relay fuse IS blown; or (2) the vehicle runs out of fuel due to an inaccurate fuel gauge reading resulting from an electrical short between the fuel pump wiring and the level sensor wiring. Gm's analysis of five assemblies returned from incident vehicles determined that the condition IS caused by elevated resistance/ arcing at the mra undercover b cavity terminal of the four-way 150 metri-pak connector.gm attributes the high resistance and arcing to a depressed contact arm at the 150 metri-pak b cavity female terminal.gm IS continuing its investigation to complete its root cause analysis. Modular reservoir assemblies using the 150 metri-pak connectors were used by gm in several million c/k-series sport utility vehicles and pickup trucks from my 1997 through 2002, when gm released a metal mra cover and a 280 metri-pak connector in the subject vehicles.during pe04-042, odi collected information from gm concerning my 2000-2002 c/k suv's and pickup trucks.the subject vehicles comprise approximately 9 percent of production for those vehicles and about 39 percent of complaints to gm. This investigation has been upgraded to an engineering analysis to further assess the scope, frequency, and safety consequences of the alleged defect in gm c/k-series vehicles.

The automatic locking retractor (alr) IS a feature incorporated in the subject vehicle for locking the webbing to properly secure a child safety seat into a vehicle.this pe was opened based on a gm technical service bulletin stating that with certain child safety seats the webbing may not remain locked.there are no complaints in the odi database and only two complaints to gm.gm's instructions state for the final step in using the webbing lock feature to push and pull the child restraint to be sure it IS secure. If the alr IS not locked, the user would be fully aware of this condition prior to completing proper installation of the child safety seat in this vehicle.this investigation did not uncover any complaints of the alr inadvertently unlocking while the vehicle IS in motion.the emergency locking retractor (elr) feature remains available to lock the retractor in a crash.a safety-related defect has not been identified at this time and further use of agency resources does not appear to be warranted.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.see attached summary for additional information.

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.
