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.

Common on this vehicle:Corrosion or rustReduced brakingParking brakeWarning lightLeakABS activates (at low speed and the like)NoiseLoss of engine power, no acceleration

Record by record

424 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.

Component named as the cause

Work done

How it is said to have ended

  • says it was fixed8
  • says it held for a while6
  • says it came back11
  • says it did not fix it21
  • result not stated106

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 issuesUnwanted ABS activation at low speed (front wheel speed sensor mounting corrosion)6

  1. Recall2000–2002 GMC YUKON ・ —

    ABS activation recall in pickup trucks and SUVs

    1. 1Fault

      • Corrosion may occur between the front hub/bearing assembly and the wheel speed sensor; if the brakes are applied at a speed greater than 6 km/h (3.7 mph) but less than 16 km/h (10 mph), the corrosion may cause an unwanted ABS activation.
      • If this occurred where stopping distance is limited, a crash could occur.
      • The condition does not set any ABS codes and does not illuminate the ABS warning lamp.

    2. 2Finding the cause

      Steps to confirm (in the document’s order)

      1. Check the mounting surface on the sensor head for flatness against a metal machinist's scale or other straight edge, in multiple positions/directions (minimum 3).
      2. With the bearing rotated at about one revolution per second, the reading should be at least 350 ACmV; if it is less than 350 ACmV the wheel speed sensor must be replaced.

    3. 3Correction

      Repair

      1. If the mounting surface on the sensor is warped or bent, the sensor must be replaced.
      2. Thoroughly clean the wheel speed sensor mounting surface on the bearing hub with a wire brush, sandpaper, emery cloth, scotch brite or equivalent to remove any rust or corrosion.
      3. Spray two thin coats of the specified rust penetrating lubricant (corrosion inhibitor) on the complete sensor mounting surface on the bearing hub, letting it dry between coats.
      4. When the corrosion inhibitor is dry to the touch (about 10 minutes), apply a light coating of the specified grease to the complete sensor mounting surface on the bearing hub and to the sensor and O-ring.
      5. Tighten the wheel speed sensor mounting bolt to 18 N·m (13 lb ft).

  1. Recall2005 GMC YUKON ・ —

    Brake Pedal Pushrod Retainer Recall 05039

    1. 1Fault

      • The brake pedal pushrod retainer may be missing; without it the brake booster pushrod could disengage from the brake pedal, causing a loss of brakes and possibly a crash without prior warning.

    2. 2Finding the cause

      Possible causes

      • On the vehicles examined, the brake pedal clip that retains the brake pedal push rod to the brake pedal was missing.
      • The second shift operator at the assembly plant did not follow the standardized work instruction, so the clip was not always installed; only vehicles built on the second shift were found with clips missing.

      Steps to confirm (in the document’s order)

      • Inspect for the presence and proper installation of the brake pushrod retaining clip.

    3. 3Correction

      Repair

      • Install a new clip if necessary.

      Parts

      • Very few vehicles are expected to need a brake pedal pushrod retainer; if one is needed, it is ordered on a CSO (Customer Special Order). No part number is printed.

    Front Right Brake Pipe Clearance Recall

    1. 1Fault

    2. 2Finding the cause

    3. 3Correction

    Read the sentences of the record
    Cause
    VEHICLE DESCRIPTION: LIGHT DUTY PICKUP TRUCKS AND SPORT UTILITY VEHICLES. SOME OF THESE VEHICLES HAVE A CLEARANCE CONDITION BETWEEN THE FRONT RIGHT-HAND BRAKE PIPE AND THE BODY CROSS SILL THAT COULD DECREASE TO THE POINT OF ALLOWING CONTACT DURING THE LIFE OF THE VEHICLE. IF CONTACT OCCURS AND THE BRAKE PIPE BECOMES DAMAGED, IN HALF OF THE BRAKE SYSTEM THERE CAN BE A LOSS OF BRAKE FLUID AND PRESSURE. THE BRAKE WARNING LAMP WILL BE ACTIVATED WHEN THE BRAKE FLUID LEVEL REACHES THE INDICATOR LIMIT.
    Remedy
    DEALERS WILL INSPECT THE FRONT RIGHT-HAND BRAKE PIPE FOR WEAR. IF THERE ARE SIGNS OF WEAR, THIS SECTION OF THE BRAKE PIPE WILL BE REPLACED WITH A NEW DESIGNED BRAKE PIPE SECTION. IF THERE ARE NOT SIGNS OF WEAR ON THE BRAKE PIPE, THE DEALER WILL INSTALL A SPACER CLIP TO ENSURE SUFFICIENT CLEARANCE BETWEEN THE BRAKE PIPE AND THE BODY CROSS SILL.
    Consequence
    DURING BRAKING, THE PEDAL WILL BE LOWER THAN NORMAL AND STOPPING DISTANCES WILL BE LONGER. IF THIS OCCURS WHEN STOPPING DISTANCE IS LIMITED, A CRASH COULD OCCUR.

Known issuesHydro-boost brake assist and power steering share one hydraulic supply (four campaigns)1

  1. Recall2003–2004 GMC YUKON ・ 2004-04-02

    Brake Hydro-Boost Housing Relief Valve Bore Recall

    1. 1Fault

      • The relief valve bore in the brake hydro-boost module may be out of specification, which could fracture the relief valve o-ring seal inside the module.
      • If the seal fractures, the driver may hear during braking an engine compartment noise like the one made when the steering wheel is turned to a full stop, and may feel slightly higher steering effort while braking and parking.
      • Under certain driving conditions a fractured seal may require slightly more brake pedal effort for the same deceleration, which could result in a crash without prior warning.

    2. 2Finding the cause

      Possible causes

      • Inspection found a machining error in the relief bore cavity of modules produced on one of the automated boring machines used for the base housing.

      Steps to confirm (in the document’s order)

      1. Look at the color of the relief valve: if it is metallic yellow or looks like brass, no further action is required.
      2. If a yellow, pink or white paint mark is visible, no further inspection or repair is required, and any stamped number is to be disregarded.
      3. With no paint marks and a stamped number 2, 3 or 4 visible, no further inspection or repair is required.
      4. If a stamped number 1 is visible on the machined surface, the relief valve must be replaced.

    3. 3Correction

      Repair

      1. With the ignition OFF, pump the brake pedal at least ten times.
      2. Unscrew the original relief valve from the hydraulic brake booster with the tool supplied with the new relief valve.
      3. Insert the new relief valve into the bore and tighten it to 17 N·m (13 lb ft).
      4. With the master cylinder mounted flush to the booster, install the nuts and tighten them to 33 N·m (24 lb ft).

      Parts

      • Part number 10398682, VALVE KIT, P/B BOOS CONT, quantity 1 per vehicle if required.

      Part numbers printed in the document

      The numbers are as the document prints them. The name and the replacing number are what the pages of GMPartsGiant, a reseller of genuine parts and not GM, state. Aftermarket equivalents are not checked here (the links only search by number). Confirm the fit for the vehicle (VIN) before ordering.

      Caution

      • Take care when working around the accumulator, which contains high-pressure compressed gas and hydraulic fluid.
      • Do not blow compressed air into the bore or flush the valve bore with commercially available cleaners; this could damage the booster or master cylinder.

    Cause
    CERTAIN SPORT UTILITY VEHICLES, PICKUP TRUCKS, AND PASSENGER VANS FAIL TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 135, ?PASSENGER CAR BRAKE SYSTEMS.? SOME OF THESE VEHICLES WERE PRODUCED WITH AN OUT-OF-SPECIFICATION BRAKE HYDRO-BOOST HOUSING RELIEF VALVE BORE.
    Remedy
    DEALERS ARE TO REPLACE THE HYDRO-BOOST RELIEF VALVE. THE RECALL BEGAN ON JUNE 18, 2004. OWNERS SHOULD CONTACT CADILLAC AT 1-866-982-2339; CHEVROLET AT 1-800-630-2438; GMC AT 1-866-996-9463; OR HUMMER AT 1-866-486-6376.
    Consequence
    CONSEQUENTLY, THE VALVE O-RING SEAL MAY FRACTURE. STEERING EFFORTS MAY BE SLIGHTLY INCREASED WHILE BRAKING OR PARKING. UNDER CERTAIN DRIVING CONDITIONS, A FRACTURED SEAL MAY REQUIRE A SLIGHT INCREASE IN THE APPLIED BRAKE PEDAL EFFORT TO ACHIEVE THE SAME VEHICLE DECELERATION RATE AS PRIOR TO THE SEAT FRACTURE.

    Brake hydro-boost module relief valve o-ring seal failure

    1. 1Fault

    2. 2Finding the cause

    3. 3Correction

      Not stated

    Read the sentences of the record
    Cause
    On certain vehicles, the relief valve o-ring seal within the brake hydro-boost module could fail. If this happens during braking applications, the driver may be able to hear an engine compartment noise similar to the sound that occurs when the steering wheel is turned to a full stop position. The driver could also experience a slight increase in steering efforts while braking and parking. Under certain driving conditions, a slight increase in the applied brake pedal effort may be required to achieve the same vehicle deceleration rate as prior to the seal failure. Correction: Dealers will inspect the hydro-boost module, and replace it, if necessary.
