1999 Chevrolet Silverado 1500 — Known Issues & Recalls

Your brake lines have rusted through and burst while you were driving. The rear brake line failed first, and a few months later the front brake line failed. Both times the vehicle was in motion, which could have caused loss of braking ability. The brake lines will need to be replaced with new ones that resist corrosion.

Your brake lines have rusted and broken, which caused you to lose braking ability and nearly have an accident. The brake line materials appear to be prone to corrosion and rust, creating a serious safety problem. You'll likely need to have the brake lines replaced, possibly with higher-quality stainless steel alternatives.

Your anti-lock braking system is engaging when it shouldn't, particularly at low speeds while driving. This unexpected braking can be dangerous and unpredictable. The issue likely involves diagnosing the ABS module, wheel speed sensors, or brake system hydraulics to determine why the system is activating improperly.

Your truck's brake system completely failed when a rusted steel brake line burst while you were slowing down on a downhill street. You narrowly avoided hitting the vehicle in front of you and were only able to stop by shifting into reverse before reaching the highway. The rusted brake lines will need to be replaced with new steel or stainless steel lines to restore proper braking function.

While you were pulling into a parking spot, your anti-lock brakes suddenly locked up, and your truck nearly hit a tree. This issue matches symptoms from a known recall (NHTSA campaign 05V379000), but you don't remember being notified about it. Your dealership scheduled an appointment to perform the recall repair, though the truck wasn't fully diagnosed before the appointment was made.

When a mechanic tried to lift your truck for an oil change, the frame buckled because rust had severely weakened it in multiple areas. Despite the truck looking and running well with only 104,000 miles, the frame has become soft and structurally compromised from corrosion. This is a serious structural safety issue that will require extensive frame repair or replacement, and the vehicle may not be safe to drive until addressed.

Your truck's frame broke directly above the rear axle, causing the bed to become misaligned with the cab. This is a structural failure that compromises the integrity of your vehicle. Frame repair or replacement will likely be necessary to restore proper alignment and safety.

Your truck's spare tire, which hangs underneath the rear of the vehicle, fell off into traffic while you were making a slow turn at 4 mph on a city street. The small cable that secures the spare tire rusted completely through and failed. This is a serious safety hazard that could cause injury to other vehicles or pedestrians.

You've noticed a gap forming between your truck's cab and bed, and the subframe underneath is showing corrosion and rust spots. Your check engine light is on, and a mechanic recommended replacing the catalytic converter, though you're unsure if that's the real issue.

You were involved in a rear-end collision while driving at 65 mph, but your airbags failed to deploy during the crash. This is a serious safety concern since airbags are designed to protect you in exactly this type of accident.

While parked, you tried to accelerate and suddenly lost the ability to steer your truck. The bolts connecting the steering gearbox to the frame had sheared off, likely due to being over-tightened. The dealer noted the bolts appeared to have been torqued too tightly during assembly or a previous service. Fixing this will require replacing the sheared bolts and reattaching the gearbox with proper torque specifications.

While driving at 70 mph, your driver's seat unexpectedly slid forward on its track, causing you to bump hard into the steering wheel and dashboard. A dealer found that plastic seat holders under the seat had cracked, allowing the seat to move. The seat rail will need to be replaced to fix this problem.

Your truck's security system (Passlock) is randomly shutting down the engine during startup about 1 in 4 times, forcing you to go through a 30+ minute reset process to get it running again. This repeated draining of your battery has left you stranded multiple times, including a recent 3.5-hour roadside situation. The fix likely involves diagnosing the Passlock security module, checking the ignition switch, or replacing the engine control module that manages this system.

While your truck was parked, you noticed a strange smell coming from inside the cabin. When you tried to open the hood to investigate, the hood latch wouldn't release. You then saw flames under the hood, which appeared to have started in the fuse box and burned the engine wiring harness. The fire department extinguished the fire, and a police report was filed. No one was injured, but the truck was towed away and has not been inspected or repaired by a mechanic. Addressing this issue will likely require a complete electrical system inspection and replacement of the fuse box, wiring harness, and any damaged engine components.

Your engine is stalling while driving at highway speeds (50-60 MPH) without warning, though a warning light appeared during at least one incident. The engine restarts after stalling, and the dealer's diagnostic test couldn't identify a specific fault code. This could leave you stranded on the road without power steering or brakes while coasting to safety. The problem may be related to fuel delivery, ignition timing, or sensor issues that need further diagnosis.

Your truck's frame and suspension components have severe rust and corrosion. When you close the driver's door, pieces of corroded metal are actually falling off the frame. A mechanic has confirmed this level of deterioration is unusually severe even for a vehicle in a harsh climate.

Fuel is leaking from where the fuel crossover tube connects to the passenger side fuel rail on your truck. This is a fuel system leak that needs prompt attention to prevent fuel odor and potential safety issues. The repair will likely involve inspecting and resealing or replacing the connection point between these fuel system components.

While driving at 15 mph, your transmission failed and wouldn't accelerate properly. A mechanic found that internal transmission parts in first gear were damaged and the entire transmission needed replacement. Additionally, you noticed brake fluid leaking from your vehicle—inspection revealed the brake lines had rusted and corroded, which was fixed by replacing them. The fixes may involve a full transmission rebuild or replacement and new brake lines.

Your front driver-side tire developed a sidewall compound issue at 60,000 miles. You added air to the tire, but the compound remained on the sidewall. The tire was not replaced. This may require tire replacement or sidewall repair to ensure safe driving.

Your truck makes an abnormal knocking noise when you start it. The plastic rollers on both the driver and passenger seat tracks are cracked, which allows the seats to slide around unexpectedly. The fix will likely involve replacing the damaged seat track rollers and investigating the engine knock, which may require an engine inspection or valve timing diagnosis.
