On the 2000-2013 Chevrolet Silverado 1500, 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 little warning. This is widely documented in owner communities and service literature because the failure can dump a large amount of oil very quickly and risk engine damage.

This issue also affects: Cadillac Escalade, Chevrolet Express, Chevrolet Suburban

Common Symptoms

engine oil leak at front of truck
oil spots on driveway
low oil pressure warning
burning oil smell
oil sprayed on frame or underbody
sudden drop in engine oil level

How to Fix

Inspect both cooler lines for wetness at the crimps, seepage at the fittings, and damaged retaining clips. The proper repair is replacement of the leaking lines and, if needed, the adapter fittings/seals with updated parts; many technicians replace both lines together due to age. After repair, verify oil level, clean the underside, and recheck for leaks under operating temperature and pressure.

On the 2000-2006 Chevrolet Silverado 1500, on 4.8L, 5.3L, and 6.0L GMT800 V8 trucks, the valley-mounted knock sensors and harness are prone to water intrusion from the cowl/intake area. Moisture corrodes the sensors or harness connectors, leading to false knock readings, a check engine light, and timing retard that can make the truck feel sluggish. This is one of the best-known early Silverado engine electrical issues and is heavily documented by owners and repair shops.

This issue also affects: Cadillac Escalade, Chevrolet Express, Chevrolet Suburban

Common Symptoms

check engine light
reduced power or sluggish acceleration
poor fuel economy
intermittent spark knock timing retard
engine runs normally but stores knock sensor codes

How to Fix

Diagnosis should confirm sensor circuit faults and inspect the harness and sensor wells for corrosion or standing water. Repair typically includes replacing both knock sensors, the sub-harness, intake gaskets, and the rubber seals/grommets, while cleaning the valley and addressing any water entry path. Using dielectric protection and updated sealing practices helps prevent repeat failures.

What Owners Are Using

Parts and tips from 0+ owners who fixed this issue

TipReplace both sensors and the harness at the same time; doing only one sensor often leads to another intake removal later.
TipClean the sensor wells thoroughly and reseal the grommets/intake area to keep water from pooling in the valley.

On the 1999-2007 Chevrolet Silverado 1500, owners in salt-belt states widely report severe corrosion of the steel brake lines on GMT800 Silverado trucks, sometimes resulting in sudden line rupture during braking. Failures often occur near the ABS module, frame rails, or underbody clips where moisture and road salt accumulate. This is a serious safety issue documented in large numbers of NHTSA complaints and owner reports, with many trucks losing most braking force without prior warning beyond a soft pedal or visible rust.

This issue also affects: Ford F-150, GMC Sierra 1500

Common Symptoms

brake pedal suddenly goes to floor
brake fluid leak under truck
visible rust on brake lines
reduced braking power
ABS warning light after line failure

How to Fix

Inspect all hard brake lines from the master cylinder/ABS unit to the rear axle and front calipers, especially if the truck is operated in rust-prone regions. The durable repair is full replacement of corroded lines with pre-bent stainless kits or nickel-copper line rather than patching only the burst section. Bleed the system thoroughly and inspect fuel lines at the same time because they often corrode in similar areas.

On the 2007-2009 Chevrolet Silverado 1500, 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 issued a safety recall for the heated washer module due to the fire risk.

Common Symptoms

burning smell from engine bay
smoke from under hood
washer heater inoperative
battery drain
melted wiring or connector near washer heater module
blown fuse

How to Fix

Confirm whether the truck is equipped with the heated washer system and check recall completion status by VIN. The recall remedy involved disabling or replacing the module depending on campaign stage; any signs of melted wiring, blown fuses, or heat damage should be repaired before returning the vehicle to service. If the system remains active outside recall repair, disconnecting the module until proper repair is completed is prudent.

On the 2003-2007 Chevrolet Silverado 1500, a very common GMT800 Silverado problem is failure of the instrument cluster stepper motors, which causes the speedometer, tachometer, fuel, oil pressure, voltmeter, or coolant temperature gauges to read erratically or stick at incorrect positions. Owners report needles pegging past full scale, dropping to zero, or becoming inaccurate enough to create drivability and fuel-range uncertainty. GM acknowledged the issue with special coverage on many trucks, and it is heavily documented in owner complaints and repair forums.

This issue also affects: GMC Sierra 1500, GMC Yukon XL, GMC Sierra 3500HD

Common Symptoms

speedometer reads too high or too low
fuel gauge stuck on empty or full
tachometer or oil pressure gauge erratic
multiple gauges inoperative
backlighting issues in cluster

How to Fix

Diagnosis is usually straightforward by comparing scan-tool data to gauge readings and checking whether multiple gauges behave abnormally. Repair typically involves rebuilding the cluster with updated stepper motors and replacing failed backlighting bulbs if needed, or installing a professionally remanufactured cluster programmed for the truck's mileage and options. Verify charging voltage and grounds before condemning the cluster.

On the 2000-2007 Chevrolet Silverado 1500, a very common GMT800 Silverado problem is contamination of the EVAP canister vent valve/solenoid by dust, road debris, or water intrusion. When the vent cannot flow properly, the truck sets EVAP leak or vent performance codes and may repeatedly shut off the gas pump during refueling. GM issued service bulletins and updated vent relocation kits for trucks used in dusty environments.

This issue also affects: Chevrolet HHR, Ford Mustang, Ford Ranger

Common Symptoms

check engine light
fuel nozzle clicks off repeatedly while filling
EVAP small or large leak codes
failed emissions inspection
intermittent fuel smell near rear of truck

How to Fix

Diagnosis includes smoke testing the EVAP system, commanding the vent valve with a scan tool, and inspecting the vent hose/filter for blockage. Repair usually involves replacing the vent solenoid and installing the updated relocated vent hose/filter kit to move the inlet away from road splash and dust. Clearing codes without updating the vent routing often leads to repeat failures.

What Owners Are Using

Parts and tips from 0+ owners who fixed this issue

TipInstall the updated relocated vent kit rather than only replacing the valve; the relocation is what usually prevents repeat clogging.
TipIf the truck is hard to fill with fuel, inspect the vent line and canister area for mud and spider/debris buildup before replacing the fuel tank or pump.

On the 2000-2007 Chevrolet Silverado 1500, gMT800 Silverado tailgate support cables are known to corrode internally and snap, sometimes with little visible warning. When one or both cables fail, the tailgate can drop unexpectedly, damaging cargo or injuring the user. This issue was serious enough to result in a GM safety recall covering many pickups in salt-belt and high-corrosion regions.

Common Symptoms

tailgate drops unevenly
frayed or rusted tailgate cables
tailgate falls open suddenly
visible corrosion at cable ends
tailgate support feels weak

How to Fix

Inspect both tailgate cables for fraying, rust swelling near the ends, cracked coatings, and weak attachment hardware. Replace both cables as a pair with updated parts if any corrosion is present, and verify the tailgate pivots and latches are not binding. Trucks that already received recall parts should still be inspected periodically in harsh climates.

On the 2000-2013 Chevrolet Silverado 1500, 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 integrated into the hub assembly, ABS and traction control warnings may appear as the bearing deteriorates. Excessive play can eventually affect braking feel and tire wear.

This issue also affects: Chrysler 300, Ford Transit Connect, GMC Sierra 1500

Common Symptoms

growling or humming from front wheel area
noise gets louder with speed
ABS light on
traction control warning
wheel play or looseness
uneven tire wear

How to Fix

Road-test to identify which side changes noise during lane shifts, then confirm by checking for roughness or play with the wheel off the ground and reviewing wheel speed sensor data. Replace the complete hub assembly rather than attempting to service the bearing separately. After installation, verify sensor connector condition and torque the axle nut and mounting bolts to specification to avoid premature repeat failure.

On the 2000-2013 Chevrolet Silverado 1500, 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. Owners often notice one side blowing hot while the other stays cold, air stuck on defrost, or recirculation not functioning correctly. The small plastic gears inside the actuators wear or strip, and recalibration may not restore operation once gear damage occurs.

This issue also affects: Chevrolet Equinox, GMC Sierra 1500, GMC Yukon XL

Common Symptoms

clicking noise behind dash
air stuck on defrost or floor
driver and passenger temperatures do not match
no change when temperature knob is moved
recirculation door inoperative

How to Fix

Use the HVAC self-recalibration procedure or disconnect the battery/HVAC fuse to see whether the actuator relearns; if the clicking returns, replace the failed actuator. Access varies by actuator location, with some easy under-dash replacements and others requiring more dash disassembly. After replacement, perform recalibration so the control head learns the new actuator limits.
