What is the 2015-2018 Chevrolet Suburban Suburban Brake Assist Loss From Decreasing Vacuum Pump Output - Recall 19V645000?

2015-2018 Chevrolet Suburbans are covered by GM safety recall 19V645000. GM determined the vacuum produced by the vacuum pump may decrease over time, and the brake booster depends on that vacuum to do most of the work of applying the brakes. On a vehicle as heavy as the Suburban,… Severity: high.

What is the 2007-2025 Chevrolet Suburban AFM/DFM Lifter Failure (5.3L/6.2L V8)?

The Active Fuel Management (AFM) and Dynamic Fuel Management (DFM) systems on the 5.3L and 6.2L V8 engines deactivate cylinders to save fuel by collapsing hydraulic valve lifters. These lifters have a complex locking pin mechanism that fails, causing the lifter to collapse and th… Repairs typically run $1,500-$4,000. Severity: high.

What is the 2003-2007 Chevrolet Suburban Reduced Engine Power / Throttle Body (TAC) Failure?

The electronic (drive-by-wire) throttle system triggers a 'Reduced Engine Power' / 'Engine Power Is Reduced' limp mode that sharply limits acceleration and speed - dangerous when it strikes in traffic. The cause is usually the throttle actuator control (TAC): worn internal thrott… Repairs typically run $200-$500. Severity: high.

What is the 2007-2014 Chevrolet Suburban Brake Line Corrosion (Rust Belt)?

Same brake line corrosion issue as all GMT900 full-size vehicles. Steel lines corrode in salt states and can rupture without warning. Repairs typically run $500-$1,500. Severity: high.

What is the 2015-2020 Chevrolet Suburban 8L90 Transmission Shudder?

Same 8L90 torque converter shudder as Tahoe/Silverado/Escalade. Light throttle shudder between 25-50 mph. GM Customer Satisfaction Program 18302 extends coverage to 6yr/100k. Repairs typically run $500-$4,500. Severity: high.

What is the 2003-2006 Chevrolet Suburban Instrument Cluster Gauge Failure (Stepper Motor)?

The 2003-2006 (GMT800) analog cluster uses tiny Switec/Juken X27.168 stepper motors to drive each gauge needle. These motors wear and lose steps, so the speedometer, tachometer, fuel, and temperature gauges stick, read wildly wrong, sweep erratically, or drop to zero while drivin… Repairs typically run $150-$400. Severity: high.

What is the 1994-2006 Chevrolet Suburban 4L60E Transmission 3-4 Clutch Failure / Loss of 3rd & 4th?

The 4L60E automatic behind the half-ton Suburban is notorious for burning up the 3-4 clutch pack. The 3-4 apply circuit is long and loses pressure as valve-body bores wear, so the clutches overheat and glaze. Symptoms are slipping in 3rd/4th, a jump from 2nd straight to 4th, or a… Repairs typically run $1,500-$3,500. Severity: high.

What is the 2007-2020 Chevrolet Suburban Rear A/C Line Corrosion and Leak?

The Suburban has a rear A/C system with refrigerant lines that run the full length of the vehicle underneath, exposed to road salt, debris, and moisture.

What is the 1996-2000 Chevrolet Suburban 5.7L Vortec CSFI 'Spider' Poppet Injector Failure?

GMT400-era Vortec V8s use a Central Sequential Fuel Injection (CSFI) 'spider' assembly with poppet-valve nozzles inside the intake. The poppet valves clog with carbon or the nozzle seats fail, so they leak/dribble fuel instead of atomizing. This causes hard starting, misfires, ro… Repairs typically run $350-$800. Severity: medium.

What is the 1999-2006 Chevrolet Suburban Erratic Fuel Gauge / Fuel Level Sensor Failure?

The in-tank fuel level sending unit reads incorrectly on these Suburbans - the gauge sticks, bounces, reads full or empty regardless of actual level, or drops to E with a low-fuel light on a full tank. The failure is the sensor card/wiper: aggressive sulfur and ethanol in modern… Repairs typically run $150-$450. Severity: medium.

What is the 1999-2007 Chevrolet Suburban Exhaust Manifold Bolt Breakage / Cold-Start Tick?

The exhaust manifold retaining bolts fatigue and snap from repeated heat-cycling on the Vortec V8s. As clamp load is lost the manifold-to-head seal leaks, producing a ticking/chuffing 'exhaust leak' noise that is loudest on cold start and quiets as the metal expands and warms. Ow… Repairs typically run $200-$700. Severity: medium.

What is the 1994-2007 Chevrolet Suburban Front Wheel Hub Bearing Failure (ABS Light)?

The sealed front wheel bearing/hub assemblies on 4WD Suburbans wear out and are a top high-mileage complaint. Because the ABS wheel-speed sensor is integrated into the hub, a failing bearing (or a failed sensor) commonly triggers the ABS and traction/StabiliTrak warning lights al… Repairs typically run $150-$450. Severity: medium.

What is the 2015-2025 Chevrolet Suburban Steering Column Lock and Click Noise?

The 2015+ Suburban uses an electronic steering column lock that can malfunction, causing a clicking noise from the steering column, failure to recognize the key fob, or preventing the vehicle from starting. The electronic lock module replaces the traditional key-cylinder lock and… Repairs typically run $150-$800. Severity: medium.

What is the 2000-2025 Chevrolet Suburban Transfer Case Fluid Leak?

The transfer case on the 4WD Suburban develops fluid leaks from the front and rear output shaft seals, the input shaft seal, or the case halves where the case splits. The NP246 (half-ton) and NP261/NP263 (heavy-duty) transfer cases all share this tendency. Low transfer case fluid… Repairs typically run $50-$1,000. Severity: medium.

What is the 2000-2007 Chevrolet Suburban Vortec Intake Manifold Gasket Leak (Vacuum/Oil)?

The Gen III/IV LS-based Vortec V8s use a plastic (nylon) intake manifold with molded silicone/rubber gaskets. With heat cycling and age the gaskets harden and crack, creating an unmetered vacuum leak that leans out the mixture and can weep oil at the manifold-to-head sealing surf… Repairs typically run $250-$650. Severity: medium.

What is the 2007-2014 Chevrolet Suburban Dashboard Cracking?

The dashboard on 2007-2014 Suburbans develops extensive cracking across the top surface due to UV exposure and heat cycling. The dashboard material shrinks and hardens over time, causing deep fissures that spread across the full width of the dash. The cracking is worst in souther… Repairs typically run $50-$3,000. Severity: low.

What is the 1999-2007 Chevrolet Suburban HVAC Blend Door Actuator Failure (Clicking Dash)?

The plastic gears inside the HVAC blend/mode door actuators strip out, so the door can't move. The classic symptom is a repetitive clicking or tapping from behind the dash (near the glovebox/center) when starting the truck or changing temperature, plus one side blowing hot while… Repairs typically run $80-$250. Severity: low.
