The 4L60E 4-speed automatic behind the half-ton Silverado is notorious for wearing out its 3-4 clutch pack and cracking the input 'sun shell' (reaction sun gear shell) as mileage climbs. Owners report the truck suddenly loses 3rd and 4th gear (revs up but won't pull) while revers… Repairs typically run $1,500-$2,800. Severity: high.
The original galvanized-steel brake (and fuel) lines on these trucks lack the modern nylon/PVF anti-corrosion coating, so in cold-weather/road-salt states the lines rust from the outside in and rupture. A brake-line burst causes sudden, often warning-light-free loss of brake pres… Repairs typically run $300-$1,200. Severity: high.
P0700 is not a specific fault by itself — it is an umbrella/MIL-request code the ECM stores whenever the transmission control module (TCM) detects an internal transmission problem and asks the ECM to turn on the check-engine light. On the Silverado 1500 it almost always appears a… Repairs typically run $300-$1,600. Severity: high.
Silverado V8 trucks commonly develop leaks at the crimped sections of the engine oil cooler lines or at the quick-connect fittings near the radiator/oil cooler adapter. Owners often report sudden puddles of oil, oil sprayed under the truck, or a rapid drop in oil pressure with li… Repairs typically run $250-$900. Severity: high.
Some GMT900 Silverado 1500 trucks equipped with the heated windshield washer fluid system experienced internal shorts in the washer heater module. Owners reported smoke, melting components, dead batteries, and in some cases underhood fires even when the truck was parked. GM issue… Repairs typically run $0-$400. Severity: high.
Silverado 1500 trucks equipped with electronic shift transfer cases commonly develop failures in the transfer case encoder motor, mode position sensor, or related switch/module circuitry. Owners report the truck getting stuck in 2HI, 4HI, or 4LO, flashing selector lights, or disp… Repairs typically run $250-$1,200. Severity: medium.
GM's small-block V8s (Gen III/IV LS and Gen V LT) in the Silverado 1500 are notorious for snapping exhaust manifold bolts. The steel bolts and the aluminum cylinder heads expand and contract at different rates through countless heat cycles, fatiguing the bolts until the heads sna… Repairs typically run $250-$900. Severity: medium.
The full-size Silverado 1500 is one of the most frequently targeted vehicles in the U.S. for catalytic converter theft. Its high ground clearance and underbody-mounted, easily reached converters let thieves cut them out in seconds, often in broad daylight, and lifted trucks are e… Repairs typically run $300-$3,000. Severity: medium.
GMT800/GMT900 Silverados are notorious for rusting out the rocker panels (below the doors) and cab corners (lower rear corners of the cab).

The mechanical (belt-driven) water pump on the LS/LT V8 Silverado 1500 is a common wear-out item. The internal shaft seal fails and coolant seeps from the pump's weep hole, often appearing as orange/Dex-Cool residue or a puddle at the front-center of the truck; the weep-hole drip… Repairs typically run $200-$1,450. Severity: medium.
Silverado 1500 trucks commonly develop front hub bearing wear, especially on higher-mileage 4x4s and trucks used on rough roads or with oversized tires. Owners report a humming or growling noise that changes with speed and steering input, and because the wheel speed sensor is int… Repairs typically run $250-$800. Severity: medium.
The engine oil pressure sensor/sending unit on LS truck V8s commonly fails or gets its screen clogged with sludge, sending the dash gauge bouncing, pegging high, dropping to zero, or reading falsely low—often with an 'oil pressure' warning even though actual pressure is fine. GM… Repairs typically run $20-$120. Severity: low.
GMT900-generation Silverado 1500 trucks (and platform-mates Tahoe/Suburban/Avalanche/Sierra/Yukon/Escalade) are widely reported to develop long cracks and splits across the top of the dashboard pad, typically radiating from the passenger airbag seam, defroster vents, and the corn… Repairs typically run $150-$1,200. Severity: low.
Silverado owners across both GMT800 and early GMT900 generations frequently report a clunk or knock felt in the steering column/floor area, especially over small bumps or while turning into driveways. The issue is commonly traced to play or binding in the intermediate steering sh… Repairs typically run $80-$450. Severity: low.
A frequent Silverado complaint is failure of the HVAC mode or blend door actuators, which causes repetitive clicking from behind the dash and leaves the system stuck on one vent mode or one temperature setting.
