What is the 2000-2006 Chevrolet Tahoe In-Tank Fuel Pump Module Failure (Long Crank / No-Start)?

The GMT800 Tahoe's in-tank electric fuel pump module is a common high-mileage failure. As the pump wears it struggles to build and hold the ~58-62 PSI these returnless systems need, producing extended cranking (worst after the truck sits overnight), stalling, hesitation under loa… Repairs typically run $400-$800. Severity: high.

What is the 2000-2002 Chevrolet Tahoe Recall 05V379 — Wheel Speed Sensor Corrosion and Unwanted ABS Activation?

The 2000-2002 Chevrolet Tahoe is included in NHTSA recall campaign 05V379000 for unwanted antilock brake system activation. What the owner experiences is the ABS stepping in without cause; what it costs is braking performance, because the recall consequence is stated plainly as i… Severity: high.

What is the 1995-2010 Chevrolet Tahoe 4L60E Automatic Transmission 3-4 Clutch Failure (Loss of 3rd/4th Gear)?

The 4L60E 4-speed automatic behind the Vortec V8s is the single most common major failure on high-mileage Tahoes. The 3-4 clutch pack is the known weak point: its friction plates burn up, and the truck suddenly slips or drops out of 3rd and 4th gear (RPMs flare with no accelerati… Repairs typically run $1,800-$3,500. Severity: high.

What is the 2000-2010 Chevrolet Tahoe 'Reduced Engine Power' Limp Mode - Electronic Throttle (TAC) System?

Tahoes with drive-by-wire throttle (APP pedal sensor + TAC module + electronic throttle body) commonly trigger a 'Reduced Engine Power' message and drop into limp mode with severely limited acceleration - a safety concern in traffic. On GMT800s the frequent culprits are a broken/… Repairs typically run $120-$450. Severity: high.

What is the 1996-2007 Chevrolet Tahoe Lower Intake Manifold Gasket Coolant Leak (Dex-Cool Erosion)?

Vortec V8 Tahoes are well known for lower intake manifold gasket leaks, most often at the driver-side rear corner coolant passages. Dex-Cool (orange) coolant is hard on these gaskets, softening/distorting them and eroding the aluminum sealing surface, allowing coolant to weep ext… Repairs typically run $700-$1,100. Severity: medium.

What is the 2000-2006 Chevrolet Tahoe Upper Intermediate Steering Shaft Clunk (I-Shaft)?

The upper intermediate steering shaft (I-shaft) between the steering column and the gearbox develops dry, corroded splines that bind and then slip, producing a clunk or knock felt in the steering wheel when turning at low speed or driving over bumps. GM issued TSB 00-02-35-003M a… Repairs typically run $120-$450. Severity: medium.

What is the 2000-2006 Chevrolet Tahoe EBCM / ABS Module Failure & Corroded Ground (ABS, Traction, StabiliTrak Lights)?

GMT800 Tahoes commonly light the ABS, Traction Control and (on later trucks) StabiliTrak warnings simultaneously due to the Electronic Brake Control Module (EBCM) or, very often, its corroded frame-mounted ground. The dedicated EBCM ground on the driver-side frame rail is exposed… Repairs typically run $100-$700. Severity: medium.

What is the 2000-2006 Chevrolet Tahoe Worn Steering Gearbox - Sector Shaft Play & Seal Leak (Loose/Wandering Steering)?

The recirculating-ball steering gearbox on GMT800 Tahoes becomes notoriously sloppy with mileage. Internal wear of the worm/sector gear and bearings produces excessive on-center steering play, vague/wandering tracking at highway speed, and a clunk, while the sector-shaft (pitman)… Repairs typically run $300-$650. Severity: medium.

What is the 2000-2010 Chevrolet Tahoe Blower Motor Resistor Failure (Heater/AC Fan Only Works on High)?

On manual-A/C Tahoes the blower motor resistor (that controls fan speeds 1-4) is a very common failure. Classic symptom: the fan works only on the highest setting (High bypasses the resistor) while the lower speeds are dead; sometimes all speeds quit, and a burning-plastic smell… Repairs typically run $50-$200. Severity: low.

What is the 2000-2010 Chevrolet Tahoe Knock Sensor Corrosion / Water Intrusion Under Intake (P0327 & P0332)?

On Gen III/IV small-block V8s the two knock sensors sit down in a recessed valley UNDER the intake manifold. Water (rain, car washes, snow melt) collects in the recess and corrodes the sensors and their two-wire harness, setting P0327 (Bank 1 low) and/or P0332 (Bank 2 low), often… Repairs typically run $250-$650. Severity: low.
