Consumer Guide's® Auto Editors have scoured repair bulletins and questioned mechanics to search for commonly occurring problems for a particular vehicle. In some cases we also give possible manufacturer-suggested solutions. In many instances these trouble spots are Technical Service Bulletins posted by the manufacturer, however, we have our own expert looking at additional vehicle problems.

Air conditioner: Cabin air filter dust cover screws can puncture the HVAC case causing water to leak onto floor when using air conditioner. (2000)

Climate control: Low output of the rear heater in very cold weather is due to a restrictor in the T-coupling. A revised coupling is offered. (2000-01)

Oil leak: An oil leak may be created by the front driveshaft hitting the oil filter on 4x4 models with the 7.4L engine. An adapter will relocate the filter. (2000)

Rough idle: Debris buildup in throttle body leads to high accelerator pedal effort and/or uneven idle. Requires installation of an air bypass plug. (2000-02)

This table lists costs of likely repairs for comparison with other vehicles. The dollar amount includes the cost of the part(s) and labor (based on $50 per hour) for the typical repair without extras or add-ons. Like the pricing information, replacement costs can vary widely depending on region. Expect charges at a new-car dealership to be slightly higher.

2000 Suburban: Hydraulic pump driveshaft could fracture, resulting in immediate loss of power-steering assist; on vehicles with hydro-boost power brakes, the same condition could result in loss of braking assist after the reserve pressure is depleted.

2000: Clearance between front right-hand brake pipe and body cross sill could decrease to the point of allowing contact, which could result in damage and loss of brake fluid and pressure.

2000-01 Suburban: Fuel pump wires in reservoir assembly may overheat under certain operating conditions; if ignition wire is exposed, fuel pump fuse will blow, causing engine stall or non-start condition or possible fuel leakage.

2000-01: Rear wheelhouse plugs may be loose or missing, allowing exhaust gases to flow forward under certain conditions and accumulate in rear wheelhouse.

2000-02 Suburban: In environmentally corrosive areas of specified "salt belt" states, unwanted antilock braking activation may occur, causing increased stopping distance during low-speed brake application.

2001: Outboard-seatbelt retractors for the 2nd and 3rd row of seats could be cracked. With repeated actuation of the locking mechanism, the crack could spread to the point such that the seatbelt would no longer lock.

2001-02 Tahoe: Rearward folding head restraints may pinch and trap fingers if protective covers are not installed.

2003: In certain extreme impacts frame cross member could tear fuel tank resulting in fuel leakage. Dealers will install a fuel-tank shield on affected vehicles.

2003-04 Tahoe/Suburban: Certain vehicles may have been produced with an out-of-specification brake relief valve, making steering difficult when braking. Dealers will inspect and replace affected parts.

2003-05 Suburban: Seatbelt routing for second-row center occupant may make it difficult to position the lap portion of the belt low around the occupant's hips.

2004-05 Suburban w/Bosch Hydro-Boost brake assembly: Hydraulic brake booster pressure accumulator may crack and separate during normal operating conditions, possibly issuing fragments and allowing fluid leakage.

2005 Suburban: Brake-pedal pushrod retainer may be missing, which could result in loss of braking.

2005 Suburban: Under certain vehicle-starting conditions, shift-lever position indicator in instrument panel may not illuminate.

2005 Suburban w/5.3-liter V8: Engine fuel rail crossover tube retainer screw could break, allowing fuel leakage and possible engine stalling; engine-compartment fire could occur if ignition source were present.

2005 Tahoe w/aftermarket leather seats: Testing has indicated that the aftermarket leather seat covers can cause the passenger sensing system to malfunction. If the passenger sensing system malfunctions, the front air bag on the passenger side may be disabled when it should be enabled, or enabled when it should be disabled. GM will purchase these vehicles for the full price paid for it (not exceeding the fair market value at the time it was bought), including taxes and fees, if the vehicle is returned to GM's possession by January 31, 2007. Through January 31, 2007, GM will also pay for the removal of any aftermarket accessories that may have been installed and return them to the customer.
