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.

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.

  1. Recall2006 GMC YUKON ・ 2005-05-10

    Power Steering Hose Fracture

    1. 1Fault

      • Under extreme steering maneuvers, such as turning the steering wheel fully left or right while braking, the hose may fracture and leak fluid; power steering assist would be lost and steering effort would increase.
      • On vehicles with hydro-boost power brakes it could also result in loss of power brake assist and increased braking effort; if the fluid sprays onto hot engine parts, an engine compartment fire could occur.
      • With the Hydroboost braking system, braking assist will be limited to the reserve power assist system; the braking systems on vehicles without Hydroboost are unaffected.

    2. 2Finding the cause

      Possible causes

      • The high pressure power-steering hose was manufactured with an incorrect compound, making it susceptible to high pressure failure at the elevated fluid temperatures and pressures that can occur during simultaneous braking and steering inputs.

      Steps to confirm (in the document’s order)

      1. Inspect and record the date code on the power steering pressure line; it is printed on the hose and repeated approximately every 6 inches (150 mm).
      2. Vehicles with the hydro-boost system have two hoses to inspect, others only one; the conduit may have to be removed to read the date code.
      3. The suspect date codes are 07135F-2 and 07145F-2; if the hose carries one of them, it must be replaced.

    3. 3Correction

      Repair

      1. If the date code is not one of the listed codes, replace the conduit if applicable; no further action is required.
      2. For Silverado/Tahoe/Sierra/Yukon/Escalade, hose replacement follows SI documents 756552 (Non Hydro-Boost Pressure line), 651043 (Power Steering Pump to Hydro-Boost Pressure line) and 651019 (Hydro-Boost to Steering Gear Pressure Line).

      Parts

      • Less than 10% of the involved vehicles will require hose replacement; if parts are required, the appropriate hose(s) are ordered from GMSPO.

      Caution

      • This bulletin is a revision to address hoses used to service 1991-2006 vehicles; dealers who ordered these hoses for service are identified in the attachment to the administrative message.
      • Vehicle eligibility should be confirmed through GMVIS before beginning recall repairs; not all vehicles within the breakpoints may be involved.

    Cause
    CERTAIN PASSENGER VEHICLES MAY HAVE BEEN BUILT WITH A POWER STEERING HOSE THAT IS NOT TO SPECIFICATION. UNDER EXTREME STEERING MANEUVERS, SUCH AS TURNING THE STEERING WHEEL FULLY TO THE LEFT OR RIGHT WHILE BRAKING, THE HOSE MAY FRACTURE AND LEAK FLUID.
    Remedy
    DEALERS WILL INSPECT THE POWER STEERING HOSE(S) FOR TWO SUSPECT DATE CODES AND REPLACE THEM IF REQUIRED. THE RECALL WILL BEGIN ON OCTOBER 14, 2005. OWNERS MAY CONTACT CHEVROLET AT 1-800-630-2438, GMC AT 1-866-996-9463, BUICK AT 1-866-608-8080, CADILLAC AT 1-866-982-2339, ISUZU AT 1-800-255-6727, OR HUMMER AT 1-800-732-5493.
    Consequence
    IF THIS WERE TO OCCUR, POWER STEERING ASSIST WOULD BE LOST AND INCREASED STEERING EFFORT WOULD BE REQUIRED. ON VEHICLES EQUIPPED WITH HYDRO-BOOST POWER BRAKES, IT COULD ALSO RESULT IN LOSS OF POWER BRAKE ASSIST AND INCREASED BRAKING EFFORT WOULD BE REQUIRED. IF THE POWER STEERING FLUID SPRAY WERE TO SPRAY ONTO HOT ENGINE PARTS, AN ENGINE COMPARTMENT FIRE COULD OCCUR.

  2. 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.

    Read the sentences of the record
    Cause
    Certain vehicles may have been built with a power steering hose that is not to specification. Under extreme steering manoeuvres, such as turning the steering wheel fully to the left or right while braking, the hose may fracture and leak fluid. If this were to occur, power steering assist would be lost and increased steering effort would be required. On vehicles equipped with hydro-boost power brakes, it could also result in loss of power brake assist and increase braking effort would be required. If power steering fluid were to spray onto hot engine parts, an engine compartment fire could occur. Correction: Dealers will inspect the power steering hose(s) for two suspect date codes and replace them if required.

    Power steering pump and line replacement procedure

    1. 1Fault

      • In rare cases there is a lack of steering assist when stopped or during parking lot type maneuvers.
      • The condition goes away or greatly improves once the vehicle begins to move or is above parking lot speeds.

    2. 2Finding the cause

      Possible causes

      • The concern can be aggravated by worn tires, low tire air pressure, low power steering pump pressures, and tires larger than stock size.

      Steps to confirm (in the document’s order)

      1. Perform the "Power Steering System Test" found in SI and make any necessary repairs based on system diagnosis.
      2. To tell whether a 670 gear box is fitted, inspect the mounting bolts that attach the stub shaft housing; a 670 gear box has only 3 mounting bolts.

    3. 3Correction

      Repair

      1. If a C/K 1500 Series vehicle is equipped with a 670 gear box, replacing it with a 680 gear box may increase the customer satisfaction.
