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

346 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 fixed3
  • says it held for a while7
  • says it came back11
  • says it did not fix it15
  • result not stated82

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)8

  1. Recall2000–2002 GMC YUKON XL ・ —

    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).

    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.

  2. Recall2003–2004 GMC YUKON XL ・ 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.

      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.

    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.

    Fault
    INTERMITTENTLY, WHEN MY 2006 GMC YUKON DENALI XL IS AT A STOP LIGHT OR SIGN AND I AM DRIVING LESS THAN 10MPH (= 16.1 km/h) AND I GO TO ACCELERATE (NOT SPINNING THE TIRES AND NOT ON WET OR SLIPPERY SURFACES) THE "TRACTION ACTIVE" MESSAGE DISPLAYS AND I LOSE ALL POWER FOR A COUPLE OF SECONDS.
    Cause
    THESE VEHICLES MAY HAVE A CONDITION PERMITTING CORROSION TO OCCUR BETWEEN THE FRONT HUB/BEARING ASSEMBLY AND THE WHEEL SPEED SENSOR.
    Inspection
    I PRINTED OFF 9 PAGES AND TOOK TO MY DEALER/SERVICE DEPARTMENT (SIMMONS ROCKWELL IN BATH, NY) AND AFTER LOOKING AT THE VEHICLE, THEY SAID THERE WAS NOTHING WRONG WITH IT.
    Consequence
    THIS MANY TIMES HAS LEFT ME IN THE MIDDLE OF AN INTERSECTION WITH ON-COMING TRAFFIC.
