2007 Chevrolet Silverado Problems: 6 Known Issues

On the 2007-2008 Chevrolet Silverado, silverado pickups from 2007 and 2008 that were built with the heated wiper washer fluid system are included in GM's 08V441000 safety recall. Inside the washer fluid heater, a short circuit on the printed circuit board can overheat the control-circuit ground wire. GM told NHTSA this may cause other electrical features to malfunction, create an odor, or cause smoke, increasing the risk of a fire. If your truck was not ordered with the heated washer fluid option, it is not affected. The recall covers 857,735 vehicles in total, not only Silverados.

On the 2003-2007 Chevrolet Silverado, gMT800 (and early-2007 'Classic') Silverados are infamous for instrument-cluster gauge failure caused by defective X27.168 stepper motors and weak solder joints behind the gauges. Over time, heat, vibration and age cause needles to stick, read wildly wrong (e.g., speedometer pegged at 120 MPH while parked, fuel gauge reading empty right after a fill-up), flicker, or quit entirely. Multiple gauges may drop out intermittently together. It is one of the most-searched older-Silverado problems and a thriving cluster-repair aftermarket exists because of it.

On the 2007-2019 Chevrolet Silverado, the 5.3L (and 6.2L) V8 with Active Fuel Management — GM's cylinder-deactivation system that drops the engine to 4 cylinders to save fuel — is notorious for collapsed AFM lifters. The special deactivating lifters (and the lifter oil-manifold/VLOM that feeds them) fail when oil pressure/timing to the lifter is compromised, causing the lifter roller to seize. A collapsed lifter no longer opens its valve, producing a dead-cylinder misfire, a loud ticking/tapping, rough idle and major power loss. If driven on, a collapsed lifter can wipe the camshaft lobe and destroy the cam, turning a lifter job into a top-end rebuild. Disabling AFM (range tuner/AFM delete) is the common owner mitigation.

On the 1999-2007 Chevrolet Silverado, gMT800 Silverados (and the related GM trucks/SUVs) in salt-belt states are widely reported to suffer rusted-through steel brake lines, leading to a sudden brake-fluid leak and loss of pedal/braking. NHTSA investigated about 2 million 1999-2003 GM trucks and SUVs sold in salt-belt states (EA11-001) after an owner petition; the agency closed it with no recall, concluding the coated-steel lines corroded at rates similar to peers. NHTSA logged 240 corroded-brake-line complaints for the 2004 Silverado/Sierra and 112 for 2006 alone. GM offered a pre-formed brake-line replacement kit via TSB (13-05-22-001) rather than a recall. Fuel lines on the same trucks rust similarly.

On the 2007-2013 Chevrolet Silverado, gMT900 Silverados (and the late GMT800) mount the fuel pump control module / fuel-system control module on an exposed frame-rail bracket where it is constantly hit with road salt, water and debris. The module's connector and internals corrode, and the FPCM then fails to drive the in-tank pump — producing extended cranking, intermittent stalling, and ultimately a crank-but-no-start with no fuel pressure. Because the pump itself is often fine, owners frequently mis-diagnose and replace the in-tank pump first. It is a common failure in salt-belt states, where the frame-mounted module is exposed to road salt.

On the 2007-2014 Chevrolet Silverado, gMT900 Silverados (and the matching Tahoe/Suburban/Sierra/Yukon) are known for the one-piece dash pad cracking — typically near the passenger airbag seam, the defroster vents and the corners. Owners attribute it to the plastic grade, UV/sun exposure and factory over-tightening of the few mounting bolts. Cracks can spread into large splits and, at the airbag seam, raise deployment concerns. Class actions were filed, but in 2021 the Sixth Circuit ruled GM was entitled to dismissal (no recall), so repairs are owner-paid. Dealer dash-pad replacement runs around $2,000, which is why dash covers and skins are a large aftermarket.
