The vehicle (where a record says)

A record is under an engine, a drive or a series only where it says so: the characters of the vehicle identification number filed with a complaint, its text, or what its document says it applies to. A record that does not say is kept as "not stated". The filed numbers and the documents do not tell 4WD from AWD.

Record by record

723 records state a cause or a remedy. Each record is shown as short labels in the order fault → finding the cause → correction. Press a label to narrow to the records that state it.

How it is said to have ended

  • says it came back6
  • says it did not fix it7
  • result not stated24

A ribbon is as wide as the records that state both of its ends (only the commonest are drawn). A record that names several symptoms or components runs through each. Orange is records that say the fault came back or was not fixed. Results come from owners’ reports only; one that does not say is “result not stated”. None of this is a likelihood of a cause or a rate at which work succeeds.

Known issuesShift lever position indicator in the instrument cluster may not illuminate (FMVSS 102) - recall 05V-0553

  1. Recall2005 GMC YUKON XL ・ —

    Automatic Transmission Shift Lever Position Indicator Illumination Recall

    1. 1Fault

      • Under certain starting conditions the shift lever position indicator in the instrument panel cluster may not illuminate; on later start-ups the condition may or may not recur.
      • If the indicator does not illuminate, the driver may not know which gear is selected and the vehicle may move in an unintended direction, possibly injuring people outside the vehicle.

    2. 2Finding the cause

      Possible causes

      • The PRNDL indicator behavior is induced only by a very specific battery voltage waveform and depends on vehicle level characteristics, while the vehicle otherwise operates normally.
      • The "blank PRNDL" anomaly appeared at the assembly plants after interim 2005 model year instrument panel cluster revisions that began on January 31, 2005.

    3. 3Correction

      Repair

      1. Dealers are to reprogram the instrument panel cluster.
      2. Prepare the vehicle for instrument panel cluster (IPC) reprogramming, then program the IPC using TIS data version 2.25.

      Parts

      • No parts are required for this recall.

      Caution

      • The service calibration is in Techline Information System (TIS) data version 2.25 and on TIS CD-ROM version 3.

Known issuesEngine fuel rail crossover tube retainer screws may break (5.3L RPO L59) - recall 04V-3762

  1. Recall2005 GMC YUKON XL ・ 2004-02-08

    Engine Fuel Rail Crossover Tube Retainer Screws

    1. 1Fault

      • The engine fuel rail crossover tube retainer screws were not made to specification and may break; if one breaks, fuel could leak from the crossover joint, the engine may stall, and with an ignition source an engine compartment fire could occur.

    2. 2Finding the cause

      Possible causes

      • The failed screw was harder than specification; the over-hardening came from a conveyor in an induction hardening operation at the fastener plant stopping or slowing excessively, exposing the screws to the hardening for too long.

      Steps to confirm (in the document’s order)

      • Inspect for blue or green paint dots on the fuel rail crossover tube assembly or on the throttle body; if there are any, go to step 13.

    3. 3Correction

      Repair

      1. Hold the fuel crossover tube retainer to the bracket on the fuel rail with locking pliers, using enough force to keep the retainer from moving without damaging any parts.
      2. Remove the fuel rail crossover tube bracket retainer screw on one side and dispose of it properly.
      3. Take the new screws out of the retainer kit (P/N 89017590) and discard the retainer brackets left in the kit.

Known issuesHydro-boost brake assist and power steering share one hydraulic supply (four campaigns)2

  1. Recall2005 GMC YUKON XL ・ 2005-08-02

    Bosch Hydro-Boost Brake Accumulator Crack Recall

    1. 1Fault

      • The hydraulic brake booster's pressure accumulator may crack and/or separate from the Hydro-Boost assembly in normal operation; if it separates with the hood open, fragments could injure people nearby.
      • The crack or fractured surface could let hydraulic fluid leak from the accumulator circuit of the booster, and the loss of fluid would increase steering and braking effort.

    2. 2Finding the cause

      Possible causes

      • The over-pressurization comes from a two-function valve (TFV) that does not open within its specified limits while the hydraulic fluid in the accumulator circuit expands as the booster is exposed to rising under-hood temperatures.

      Steps to confirm (in the document’s order)

      1. With the engine OFF, make at least five (5) high effort brake applies until the pedal feels hard.
      2. Turn the steering wheel to the steering lock (fully turned) position, hold for 1 to 2 seconds, then release; do this a total of 3 times.
      3. Install the inlet port adapter, CH 47950-2, into the booster supply port and slowly tighten it with a torque wrench to 16 N·m (12 lb ft).
      4. Install the accumulator pressure clamp, CH 47950-1, by sliding it over the accumulator so that it straddles the hydro-boost housing.
      5. If fluid comes out of the inlet port adapter at up to 65 N·m (48 lb ft) maximum torque on the clamp bolt, the hydro-boost booster assembly is OK.

    3. 3Correction

      Repair

      1. If no fluid is seen, complete Steps 19-27 and repeat Steps 1-18; if no fluid is visible in the second evaluation, replace the hydro-boost unit.
      2. After the test, reinstall the supply hose/tube to the booster and tighten to 28 N·m (21 lb ft).
      3. When the booster is replaced, install the 4 booster to bulkhead nuts and tighten them to 36 N·m (26 lb ft).

      Caution

      • The inspection uses the Hydro-Boost Checking Tool, CH 47950, shipped to each dealer.
      • After starting the engine, do not depress the brake pedal until instructed.
      • Incorrect installation of the fixture washer will damage the accumulator end.

    Cause
    CERTAIN TRUCKS, SPORT UTILITY VEHICLES, AND VANS EQUIPPED WITH BOSCH HYDRO-BOOST BRAKE ASSEMBLIES, THE HYDRAULIC BRAKE BOOSTER PRESSURE ACCUMULATOR MAY CRACK AND SEPARATE FROM THE HYDRO-BOOST ASSEMBLY DURING NORMAL OPERATING CONDITIONS.
    Remedy
    DEALERS WILL TEST THE HYDRO-BOOST ASSEMBLY FOR FUNCTIONAL OPERATION OF THE TWO-FUNCTION VALVE. IF THE HYDRO-BOOST ASSEMBLY FAILS THE TEST, DEALERS WILL REPLACE THE ASSEMBLY FREE OF CHARGE. THE RECALL BEGAN ON MARCH 23, 2005. OWNERS MAY CONTACT CHEVROLET AT 1-800-630-2438, GMC TRUCKS AT 1-866-996-9463 AND HUMMER AT 1-800-732-5493.
    Consequence
    IF A SEPARATION OCCURRED AND THE HOOD OF THE VEHICLE WERE OPEN, FRAGMENTS FROM THE ACCUMULATOR COULD CAUSE INJURY TO PEOPLE IN THE IMMEDIATE AREA.

    3. 3Correction

      Not stated

      What the documents say to do

      Hydro-boost brake assist and power steering share one hydraulic supply (four campaigns)

      Confirm

      • Perform the "Power Steering System Test" found in SI and make any necessary repairs based on system diagnosis.

      Repair

      1. Dealers replace the hydro-boost relief valve.
      2. Dealers test the hydro-boost assembly for functional operation and replace it if it fails.

      Caution

      • An inoperative pump raises steering and braking effort but does not completely remove the ability to steer or slow the vehicle.
    Read the sentences of the record
    Cause
    On certain vehicles, the hydraulic brake booster's pressure accumulator may crack and/or separate from the Hydro-Boost assembly during normal vehicle operating conditions. If a separation occurred and the hood of the vehicle was open, fragments from the accumulator could cause injury to people in the immediate area. In addition, the presence of this crack or fractured surface could allow the hydraulic fluid to leak from the accumulator circuit of the booster assembly. The loss of fluid would cause increased steering and braking effort. Correction: Dealers will test and, if necessary, replace the Hydro-Boost assembly.

    HVAC Blower Motor Resistor Module Overheating

    1. 1Fault

    2. 2Finding the cause

    3. 3Correction

      Not stated

      What the documents say to do

      HVAC blower motor resistor module / connector overheating

      Repair

      1. Dealers install a new blower motor resistor and resistor module connector.
      2. Cut the wires back far enough to remove any melted insulation.

      Caution

      • The connector must be replaced even if it was replaced in an earlier repair.
    Read the sentences of the record
    Cause
    On certain vehicles, the interface between the electrical terminals of the Heating, Ventilation, and Air Conditioning (HVAC) blower relay resistor module and the wiring connector (which powers the module) may be incapable of conducting higher current levels for sustained periods of operation. In addition, moisture and other contaminants (such as road de-icing materials) may enter the fresh air intake plenum and contact the internal circuit of the module or corrode the terminals. These conditions may cause the relay resistor module or wiring connector to overheat, causing various symptoms such as: the HVAC blower may not function on certain or all blower speed settings; a burning-plastic smell or smoke may be present in the vehicle, or; the HVAC blower may run continually with the ignition in the OFF position. These warning signs could, in certain instances, be leading indicators of an impending vehicle fire, which could result in property damage and/or personal injury. Correction: Owners will be provided with additional warranty coverage for the blower motor resistor module/wiring connector overheating condition. Under this "special warranty coverage", should this condition occur within 10 years or 240,000 km from first vehicle registration, dealers will install a replacement blower motor resistor and resistor module connector.

    Oil Consumption Measurement and Loss of Oil Service Bulletin

    1. 1Fault

      Not stated

    2. 2Finding the cause

      Possible causes

      • Towing a trailer or hauling additional weight will increase oil consumption.

      Steps to confirm (in the document’s order)

      1. The accepted rate of oil consumption for gasoline engines in vehicles at or above 8600 GVW is stated as 1 liter (1 qt) within 400 liters (100 gallons) of fuel used.
      2. Inspect the oil pans, engine covers and the engine oil cooler for leakage, and inspect for oil leakage into the engine coolant.
      3. Verify that the positive crankcase ventilation (PCV) system is operating properly; blockages, restrictions or damage to the PCV system can result in increased oil use.
      4. Wait at least 15 minutes after the engine is shut off before checking the oil level, so most of the oil has drained back into the crankcase.
      5. Check the oil level and record the vehicle mileage, date and exact oil level on the bulletin's form, then make sure the oil level is at, but not above, the full mark on the dipstick, adding oil if necessary.

    3. 3Correction

      Vehicle Wide Programming (VWP) is a new process to update software on GM Vehicles. It provides the ability via a single selection within Techline Connect to first identify which modules need updating and then proceed to updating affected modules (with some exceptions). The updating of modules is completed in parallel instead of the technician needing to update one module at a time. This allows a more streamlined approach for dealers and customers.

    Engine Oil Consumption Service Information

    1. 1Fault

      Not stated

    2. 2Finding the cause

      Possible causes

      • Towing a trailer increases oil consumption and may put it outside the normal accepted rate given for an unloaded vehicle in personal use.
      • On vehicles usually driven short distances, less than 8 km (5 mi), especially in colder weather, unburned fuel and condensation may not evaporate out of the oil, and the dipstick may show the level as over-full.

      Steps to confirm (in the document’s order)

      1. Inspect the oil pan and engine covers for leakage due to over-tightened, damaged or out of place gaskets.
      2. Verify that the dipstick tube is fully seated in the block.
      3. Let the vehicle sit for at least 15 minutes after the engine has been shut off before reading the oil level.
      4. Verify that the positive crankcase ventilation (PCV) system is operating properly; blockages, restrictions or damage to it can increase oil use.
      5. Do not test oil economy until the vehicle has accumulated at least 6400 km (4000 mi).
      1 more points

    3. 3Correction

      Repair

      • If the final evaluation shows the engine uses more than 0.946 liter (1 qt) in 3200 km (2000 mi), follow the published symptom diagnostics in the appropriate Service Manual.

      Caution

      • The accepted rate of oil consumption for these engines is 0.946 liter (1 qt) in 3200 km (2000 mi).
      • This rate does not apply to vehicles driven aggressively, at high RPM, at high speeds, or (for trucks) loaded; oil consumption under these conditions will be more.
    Read the sentences of the record

    1. 1Fault

    2. 2Finding the cause

    3. 3Correction

      Not stated

    Read the sentences of the record
    Cause
    On certain vehicles, the 2nd row centre occupant seat belt routing may make it difficult to position the lap portion of the safety belt low around the hips of occupants. A lap portion of the seat belt routing that is not low and snug on the hips can allow unfavourable occupant kinetics in the event of a crash. Moreover, the higher routing allows the lap belt to ride up on an occupant's abdomen instead of fitting low around their hipbones, and therefore, can expose them to more risk of abdominal and internal organ injury. Correction: Dealers will modify the guide loop.
