Engine

3.1L V6

• Head gasket failure: Premature failure can lead to coolant leaks or overheating. Symptoms include white smoke from the exhaust, coolant loss, and overheating. The solution is to replace the head gasket. Estimated cost to fix: $1,000-$2,000. Recalls: None found.
• Intake manifold gasket failure: Can cause vacuum leaks, resulting in rough idle, stalling, and reduced power. Symptoms include a hissing sound from the engine, decreased fuel efficiency, and engine check light. The solution is to replace the intake manifold gasket. Estimated cost to fix: $300-$600. Recalls: None found.
• Water pump failure: Premature failure can lead to overheating and engine damage. Symptoms include coolant leaks, overheating, and a squealing noise from the engine. The solution is to replace the water pump and timing belt (if equipped). Estimated cost to fix: $500-$1,000. Recalls: None found.

3.8L V6

• Intake manifold gasket failure: Can cause vacuum leaks, resulting in rough idle, stalling, and reduced power. Symptoms include a hissing sound from the engine, decreased fuel efficiency, and engine check light. The solution is to replace the intake manifold gasket. Estimated cost to fix: $300-$600. Recalls: None found.
• Ignition coil failure: Can cause misfiring and engine performance issues. Symptoms include a rough idle, reduced power, and engine check light. The solution is to replace the ignition coil. Estimated cost to fix: $100-$300. Recalls: None found.

Transmission

3-speed automatic transmission

• Shifting issues: May experience hard shifting, slipping, or no shifting. Symptoms include delayed or erratic gear changes, slipping gears, or inability to engage gears. The solution can vary depending on the specific issue, but may include replacing the transmission filter and fluid, adjusting the shift linkage, or rebuilding the transmission.

Suspension

• Strut/shock failure: Premature failure can lead to decreased ride quality and handling. Symptoms include excessive bouncing, poor cornering, and uneven tire wear. The solution is to replace the struts or shocks. Estimated cost to fix: $400-$800. Recalls: None found.
• Sway bar link failure: Can cause clunking or rattling noises when turning or going over bumps. Symptoms include a rattling or clunking noise from the front or rear suspension, particularly when turning or on uneven roads. The solution is to replace the sway bar links. Estimated cost to fix: $100-$300. Recalls: None found.

Electrical

• Alternator failure: Premature failure can lead to electrical system malfunctions. Symptoms include dimming headlights, flickering dashboard lights, and electrical component failure. The solution is to replace the alternator. Estimated cost to fix: $500-$800. Recalls: None found.
• Battery failure: Premature failure can lead to difficulty starting or electrical system malfunctions. Symptoms include difficulty starting the engine, slow cranking, or electrical component failure. The solution is to replace the battery. Estimated cost to fix: $100-$200. Recalls: None found.

Exterior

• Rust: Premature rust can affect the body panels, frame, and undercarriage. Symptoms include visible rust spots, bubbling or peeling paint, and weakened metal. The solution is to prevent or repair rust spots as needed. Estimated cost to fix: Varies depending on the extent of rust damage. Recalls: None found.

Interior
