2004 Chevrolet Tahoe — Known Issues & Recalls

Your brakes didn't work when you pressed the pedal, which caused an accident. This is a complete brake system failure that needs immediate professional diagnosis and repair to determine why the brakes failed.

Your brake pedal sank all the way to the floor when you pressed it, and your dashboard displayed a warning saying 'Stability System Disabled - Service Brake System.' You had to press hard on the brake pedal to safely move your vehicle out of a drive-thru. After restarting the engine, the problem persisted, so you parked the vehicle and haven't driven it since. The issue likely involves a loss of hydraulic pressure in your brake system, which may require inspection and repair of brake lines, cylinders, or fluid reservoirs.

While braking hard at low speed, your brake system partially failed and you had to push the pedal to the floor to stop. You discovered a ruptured brake line that was spraying brake fluid onto the catalytic converter, creating smoke and a fire risk. The brake lines had corroded despite recent brake pad and rotor service, and replacement lines are available from GM but dealer installation costs around $2,000 or more.

Your brake pedal went completely to the floor with no stopping power in both your 2004 and 2005 Tahoe trucks. In each case, the main brake line ruptured midway along the truck's undercarriage, spraying brake fluid everywhere. Both failures happened during highway driving, and you had to use the emergency brake to stop safely. The brake line will need to be replaced, inspected for corrosion or defects, and the entire brake system refilled and bled.

Your brake line has rusted through, causing you to lose brake fluid and brake function while driving. This is a serious safety issue that requires immediate attention. The rusted brake line will need to be replaced with a new one to restore proper braking.

Your brake pedal went to the floor when you tried to stop, and you discovered brake fluid leaking under the driver's side of your vehicle. The dealer found a blown brake line and said all the brake lines were in poor condition. You had only the leaking lines replaced instead of all of them.

While driving at 35 mph, your brake pedal went soft and sank all the way to the floor, forcing you to use the parking brake to stop. After parking, you noticed brake fluid spraying onto the ground from underneath the front of the vehicle. This suggests a significant brake system leak that could prevent your brakes from working properly.

Your brakes didn't stop the vehicle right away when you pressed the pedal while driving. The dealer found this is related to a known brake issue (NHTSA Campaign 04V045000), but your specific vehicle's VIN wasn't included in the recall, so no repair was performed. The problem happened around 150,000 miles. This will likely require brake system inspection and potentially replacing brake components like brake fluid, master cylinder, or brake lines.

Your brake master cylinder lines are leaking fluid. You may notice your brake pedal feeling soft or spongy, or brake fluid dripping under your vehicle. A mechanic confirmed the brake lines need to be replaced to restore proper braking function. The repair will involve replacing the faulty brake lines and refilling the brake fluid system.

Your 2004 Chevrolet Tahoe caught fire approximately 10 minutes after being parked. The fire department extinguished the fire, and no one was injured, but the exact origin of the fire was not determined. The vehicle was towed away and has not yet been diagnosed by a dealer or manufacturer. A fire report was filed with authorities.

Your engine's rear main seal has failed, causing oil to leak everywhere underneath your vehicle. This oil leak poses a potential fire hazard and environmental concern. The repair will likely involve replacing the rear main seal, which requires significant engine disassembly.

Your engine's main wiring harness became corroded and filled with moisture, causing your vehicle to shut off unexpectedly while driving. It took several mechanic visits to identify and fix the problem. The repair will likely involve cleaning or replacing the corroded wiring harness and addressing the moisture intrusion.

Your vehicle's electrical system stopped working without warning, causing the battery to die repeatedly. You replaced the battery multiple times, but the underlying electrical problem wasn't fixed at the dealership. The issue may require a full electrical system diagnostic to find what's draining or damaging the battery.

Your seat belt has an issue that wasn't fully described in the complaint. This is a safety component that should be inspected and repaired as soon as possible to ensure you and your passengers are properly protected in the event of a crash.

Your Tahoe's power steering and power brakes have stopped working, leaving you unable to steer easily or brake effectively—you've had to press the brake pedal with both feet at stops and can't maneuver in tight spaces like parking garages. There's a recall (#04004) for a brake hydro-boost relief valve defect affecting over 64,000 vehicles, but your VIN isn't listed on the recall even though your vehicle shows the same symptoms and manufacturing error. The fix will likely involve inspecting and replacing the brake hydro-boost assembly to restore power steering and braking function.

Your Tahoe's transfer case (New Process 246GM) may have a known defect where the internal pump rubs against the magnesium housing, creating small holes that allow fluid to leak out over time. Without adequate fluid, the transfer case can overheat and fail completely. A mechanic confirmed your transfer case has no fluid and is burned up, and a transmission shop confirmed this is a common problem with this model.

Your steering, brakes, and electronic stability/speed control systems may not be working properly. The owner is clarifying that their original complaint included issues with multiple systems including electrical components, but the form only allowed them to select three affected parts.

Your Tahoe's fuel lines above the gas tank have rusted severely and can develop leaks, causing fuel to spray out. This was discovered when fuel began leaking during engine idling. The fuel lines will need to be replaced to stop the leak.

Your rear view mirror detached from the windshield while driving. Additionally, bolts on your exhaust manifold have broken, which is causing poor fuel economy and sluggish acceleration. Reattaching the mirror and replacing the broken exhaust manifold bolts should address both issues.

Your air conditioning randomly switches from cold to warm air while driving or stopped, even though the AC is turned on and appears to be working properly. Turning the car off and back on temporarily fixes the problem, but it keeps happening repeatedly throughout your drive.
