2008 Chevrolet Impala — Known Issues & Recalls

When you press the gas pedal from a complete stop, your car hesitates and struggles to engage the transmission, then suddenly jerks hard when it catches gear. This creates a safety risk if you need to pull into traffic quickly, since the car barely moves while struggling to engage. The hard jerking motion is jarring enough to be concerning for passengers, especially small children. The issue has been checked multiple times without being resolved.

When you start your car and shift into Drive, your engine doesn't seem to move the car forward — there's no acceleration power. This suggests a problem with how your engine's power is being transferred to the wheels through your automatic transmission. The issue likely involves transmission fluid, internal transmission components, or engine performance, and will require a mechanic to diagnose and repair.

Your car is throwing two fault codes related to the gas pedal sensor and fuel mixture. Even though the accelerator pedal has been replaced twice and the codes cleared, they keep returning within 3-4 days, along with a "reduced engine power" warning message. This issue started 3 months ago and suggests either a wiring problem, connector issue, or a deeper engine control computer malfunction rather than just the pedal itself.

Your car's blend doors (which control how air flows through your heating and air conditioning system) may open unexpectedly while driving, causing your windows to fog up—especially in cold weather—which reduces your visibility and creates a safety hazard. You might also hear clicking sounds coming from the doors due to their design flaw. A mechanic confirmed this is the issue, and while the replacement parts cost under $100, labor to fix it typically runs over $1,200.

Your dashboard cover is deteriorating and pieces are crumbling off, even though you've tried to keep it protected and in good condition. Fragments are falling into the heating and cooling system's fan inside your car. Replacing the dash cover would involve removing the old cover and installing a new one to prevent debris from entering your climate control system.

The complaint submitted does not contain enough information to identify a specific vehicle problem or component that needs attention.

Your airbags failed to deploy when your car crashed into a ditch at 55 MPH, resulting in you hitting the steering wheel and suffering a concussion, facial cuts and bruises, and leg and hip bruising. The vehicle was totaled in the crash. This is a serious safety system failure that should have protected you during impact.

The pull strap on your car seat that tightens the shoulder straps isn't working properly, making it impossible to secure your child tightly enough. A certified car seat technician confirmed this isn't user error and recommended you stop using the seat immediately. The manufacturer has refused to replace it because it's out of warranty.

Your car experienced violent shaking while driving, which you traced to the rear tires. When you removed the driver's side rear tire, you found a large bulge where the tread was separating from the tire. A few months later, the passenger's side rear tire developed the same defect. Both Starfire Solarus AS All-Season tires were purchased in March 2021 and had minimal use, with treads still looking nearly new except for the bulges. A tire replacement or repair may be needed, though the defective tires should be removed immediately due to the safety risk.

Your car's engine, electrical system, and brakes suddenly shut down while driving, causing the steering wheel to lock up. The front and side airbags failed to deploy during the crash, leaving your daughter injured. There were no warning lights before this happened. The repair would likely involve a complete diagnostic of the electrical system, airbag system, and brake system to determine the root cause of the simultaneous failures.

While driving at highway speeds, your engine shuts off and you see a warning message that says "Engine power is reduced, service throttle, starter disabled." This is a serious problem because it can leave you stranded on the road. The issue likely involves the throttle control system or electrical connections that need diagnosis and repair.

Your car is shutting off while you're driving in traffic, and you're seeing a warning message that says "engine power reduced" and "service traction control." This is a serious drivability issue that could leave you stranded. The problem likely involves the engine control system, traction control module, or related sensors that need diagnostic testing and repair.

While driving at 60 mph over a pothole, your car suddenly lost power, stalled, and the steering wheel became hard to turn. You weren't able to restart the vehicle, and no warning lights came on before or during this event. Your mechanic was unable to diagnose the problem. The issue may require engine diagnostics and steering system inspection to identify why power and steering assist were lost simultaneously.

Your key gets stuck in the ignition and won't come out. When the key is stuck, the battery drains completely, leaving your car unable to start. This appears to be related to both the steering column and electrical system.

Your sway bar is broken and needs replacement. The sway bar is a suspension component that helps keep your car stable when turning, and a broken one can affect how your vehicle handles and corners. Fixing this will require removing and replacing the damaged sway bar with a new one.

Your back driver's side door won't open, even though it appears locked. This is a safety concern since you need to be able to exit through all doors in an emergency. The fix will likely involve inspecting and repairing or replacing the door latch mechanism.

Your heating and air conditioning blend door actuators are getting stuck, preventing the system from switching between hot and cold air properly. You may experience hot air suddenly turning cold (or vice versa), and in cold weather your defroster may get stuck on cold air, making it difficult to see out your windows. To temporarily fix the problem, you have to pull out the glove box and manually turn the actuators by hand. A proper repair will likely involve replacing the stuck blend door actuators.

Your car makes a clunking noise whenever you turn, and you can feel it vibrating through the floorboard—especially on rough roads. A Firestone technician has inspected it and found a suspension or steering issue. The owner is concerned that a control arm could break, which might cause you to lose control of the vehicle. Repairing this will likely involve inspecting and replacing worn suspension components like control arms or stabilizer links.

Your car vibrates and jumps while driving at highway speeds (35-40 MPH). When you inspected the front passenger side, you found the engine was moving when you removed the hub, which you believe indicates a fractured front lower control arm. This suspension problem likely needs to be repaired to restore safe handling and eliminate the vibration.

Your car keeps going into limp mode (reduced power) while driving, triggering error codes related to the accelerator pedal sensor. You've replaced the accelerator pedal sensor 6 times, the throttle body, and related connectors, but the same problem and codes keep returning. The owner suspects corrosion in the engine control module (ECM) is causing these repeated failures. A mechanic will need to diagnose whether the ECM itself is faulty or if there's an underlying electrical/corrosion issue causing the sensor failures.
