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:NoiseWarning lightCorrosion or rustLeakMisfire or rough idleAir conditioning or heaterReduced brakingLights (headlights, turn signals)

Record by record

61 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 came back1
  • says it did not fix it2
  • result not stated18

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)5

  1. Recall2002 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).

Aftermarket equivalents are not checked here (the links only search by number). Confirm the fit for the vehicle (VIN) before ordering.

      Caution

      • Remove the sensor by pulling it straight out of the bore; do not pry it with a screwdriver or other device, because prying will break the sensor body off in the bore.

    • Condition：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.
    • Condition：If this occurred where stopping distance is limited, a crash could occur.
    • Condition：The condition does not set any ABS codes and does not illuminate the ABS warning lamp.
    • Caution：Remove the sensor by pulling it straight out of the bore; do not pry it with a screwdriver or other device, because prying will break the sensor body off in the bore.
    • Confirm：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).

    Cause
    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, NEW HAMPSHIRE, NEW JERSEY, NEW YORK, OHIO, PENNSYLVANIA, RHODE ISLAND, VERMONT, WEST VIRGINIA, WISCONSIN AND THE DISTRICT OF COLUMBIA ONLY.
    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.
    Consequence
    THIS CAN CAUSE INCREASED STOPPING DISTANCES DURING LOW-SPEED BRAKE APPLICATIONS, WHICH COULD RESULT IN A CRASH.

      PRODUCT SAFETY RECALL REGARDING FRONT WHEEL SPEED SENSOR CORROSION. *TT

      What the documents say to do

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

      Confirm

      • The reading should be at least 350 mV AC; if it is less, the wheel speed sensor must be replaced.

      Repair

      1. Dealers remove the sensor, clean its mounting surface on the bearing, apply rust inhibitor and grease, reinstall it and check peak-to-peak output voltage.
      2. The passage heading states that the repair is cleaning the wheel speed sensor mounting surface.

      Caution

      • Do not pry the sensor out of the bore; prying breaks the sensor body off in the bore.

      Refinishing Aluminum Wheels This bulletin updates General Motor's position on refinishing aluminum wheels. GM does not endorse any repairs that involve welding, bending, straightening o re-machining. Only cosmetic refinishing of the wheel's coatings, using recommended procedures, is allowed. Evaluating Damage In evaluating damage, it is the GM Dealer's responsibility to inspect the wheel for corrosion, scrapes, gouges, etc. The Dealer must insure that such damage is not deeper than what can be sanded or polished off. The wheel must be inspected for cracks. If cracks are found, discard the wheel. Any wheels with bent rim flanges must not be repaired or refinished. Wheels that have been refinished by an outside company must be returned to the same vehicle. The Dealer must record the wheel ID stamp or the cast date on the wheel in order to assure this requirement. Refer to Refinisher's Responsibility — Outside Company later in this bulletin.

    Chromed Aluminum Wheels Chemical Staining and Corrosion

    1. 1Fault

    2. 2Finding the cause

      Possible causes

      • Chemical staining mostly results from acid based cleaners; the stains are frequently milky, black or greenish.
      • A second type of staining comes from road chemicals such as calcium chloride used for dust control on unpaved roads, and looks like small pitting.
      • A third type results from prolonged exposure to brake dust that penetrates the chrome.
      • If the brake material sits on the wheel while exposed to moisture or salt, it corrodes the wheel beneath the chrome and leaves a pit or small blister.

    3. 3Correction

      Repair

      1. Remove heavy brake dust build-up with GM Chrome Cleaner and Polish, P/N 1050173 (in Canada 10953013).
      2. For milky stains from acidic cleaners, after washing and drying apply 3M Chrome and Metal Polish #39527 with a clean terry cloth towel; the staining diminishes as it is applied.

      Caution

      • Do not use cleaning solutions containing hydrofluoric, oxalic and most other acids on chrome wheels or any wheels.
      • Any wheel cleaner must be thoroughly rinsed off the wheel with clean, clear water.
      • Stained wheels are not warrantable; most acid based cleaners permanently stain chrome wheels.
      • This polish reduces the thickness of the chrome plating and, if used incorrectly or excessively, may remove it altogether, exposing a less bright, brassy coloured sub-layer.
      • For spotting from road chemicals the procedure may marginally improve the condition but will not restore the finish or remove the pitting.
