What is the 2007-2020 Chevrolet Tahoe AFM/DOD Lifter Failure - V8 Cylinder Deactivation?
The Tahoe 5.3L and 6.2L V8 engines with Active Fuel Management (AFM) use collapsible hydraulic lifters that commonly fail between 80,000-120,000 miles. Failed AFM lifters cause misfires on deactivation cylinders (1, 4, 6, 7), ticking noises, and potential camshaft and cylinder wa… Repairs typically run $3,000-$6,000. 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 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 2007-2020 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 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 2007-2014 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.
