NHTSA recall 10V240000 applies to 2007-2009 Chevrolet Tahoes equipped with the heated washer fluid system. This is a repeat campaign: a 2008 recall added a fuse to the heated washer module's control circuit harness to address the consequences of a printed circuit board electrical… Severity: high.

What is the 2007-2008 Chevrolet Tahoe Washer Fluid Heater Short Circuit Fire Risk — NHTSA Recall 08V441?

Recall 08V441000 applies to 2007 and 2008 Tahoes built with the heated wiper washer fluid system. The washer fluid heater contains a printed circuit board that can short circuit; when it does, the control-circuit ground wire may overheat. According to the recall record, the resul… Severity: high.

What is the 2007-2014 Chevrolet Tahoe 5.3L Vortec Excessive Oil Consumption (Low-Tension Rings / PCV)?

Gen IV 5.3L V8s burn oil at an abnormal rate, frequently far worse than GM's own 1 qt / 2,000 mi 'acceptable' threshold. Three compounding root causes: (1) low-tension piston rings that fail to scrape oil from the cylinder walls; (2) the Active Fuel Management (AFM) oil-pressure… Repairs typically run $300-$4,000. Severity: high.

What is the 2007-2014 Chevrolet Tahoe Brake Line Corrosion and Failure (Rust Belt)?

The 2007-2014 Tahoe (and all GMT900 platform vehicles) suffer from brake line corrosion in salt-belt states. Factory steel lines corrode internally and can rupture without warning, causing complete brake failure. This is the same safety-critical issue affecting Escalade, Silverad… Repairs typically run $500-$1,500. 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 2007-2020 Chevrolet Tahoe Broken Exhaust Manifold Bolts (Startup Ticking)?

The exhaust manifold-to-head bolts on GM small-block V8s fatigue and snap after years of heat cycling, most often the front and rear bolts on each manifold. The result is a distinctive tick/puff that is loudest on a cold start and quiets as the engine warms and the manifold expan… Repairs typically run $300-$1,200. Severity: medium.

What is the 2007-2020 Chevrolet Tahoe Water Pump Failure / Coolant Leak?

The engine-driven water pump bearing and shaft seal wear out, leaking coolant from the weep hole and eventually letting the impeller wobble or the bearing seize. Coolant loss leads to overheating if ignored. It's a routine wear item on the small-block V8s, commonly needed around/… Repairs typically run $900-$1,500. Severity: medium.

What is the 2007-2014 Chevrolet Tahoe GMT900 Cracked Dashboard (Instrument Panel Splitting)?

The molded plastic dashboard on GMT900-platform Tahoes develops long stress cracks in remarkably consistent locations: to the left of the instrument cluster on the driver side and around the passenger airbag seam near the center of the dash. Owners across all climates report the… Repairs typically run $200-$2,200. Severity: medium.

What is the 2007-2020 Chevrolet Tahoe Autoride Air Suspension Compressor and Air Spring Failure?

Tahoe models with Autoride (RPO Z55) or Magnetic Ride Control (RPO Z95) use air springs and an electronic compressor that fail between 80,000-120,000 miles. Air springs crack from age causing the vehicle to sag. The compressor burns out from overwork. Same system as Escalade and… Repairs typically run $600-$3,000. 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 2007-2014 Chevrolet Tahoe Fuel Level Sensor / Sending Unit Failure (Erratic Fuel Gauge)?

The in-tank fuel-level sender's resistive card wears, causing the fuel gauge to read inaccurately — stuck on Empty or Full, bouncing/fluctuating, or dropping to E with a false low-fuel warning. The sender is integral to the fuel pump module, so a worn card typically means droppin… Repairs typically run $400-$1,400. Severity: low.

What is the 2007-2014 Chevrolet Tahoe HVAC Blend / Mode Door Actuator Failure (Clicking Behind Dash)?

The small electric HVAC door actuators use plastic internal gears that strip, crack, or lose calibration. When they fail you get a repetitive clicking or tapping noise from behind the dash (often behind the glove box or center console) that frequently repeats when you change temp… Repairs typically run $100-$450. Severity: low.

What is the 2007-2010 Chevrolet Tahoe Exterior Door Handle Cracking / Breaking Off (GMT900)?

The 2007+ GMT900 Tahoe's outside door handles are a notorious weak point. The plastic mounting bosses/studs behind the handle crack and break, so the handle goes loose, rattles, or pulls partway off and won't open the door. A GM bulletin attributes chrome-handle cracking to assem… Repairs typically run $100-$250. 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.
