• Intake Manifold Gasket Failure: Leaks occur due to a faulty gasket between the intake manifold and the engine block. Symptoms include rough idling, loss of power, and an increase in fuel consumption. Solution: Replace the intake manifold gasket. Estimated Cost to Fix: $300 - $600+
• Fuel Pump Failure: Intermittent or complete failure of the fuel pump prevents fuel from reaching the engine. Symptoms include stalling, difficulty starting, and reduced performance. Solution: Replace the fuel pump. Estimated Cost to Fix: $400 - $800+

Transmission

5-Speed Manual Transmission

• Grinding Gears: Difficult or impossible gear shifting due to worn synchronizers. Symptoms include a grinding noise when shifting gears. Solution: Rebuild or replace the transmission. Estimated Cost to Fix: $2,000 - $3,500+
• Clutch Problems: Slipping or chattering clutch causes difficulty engaging or disengaging gears. Symptoms include a burning smell, excessive clutch pedal travel, or gear slippage. Solution: Replace the clutch components. Estimated Cost to Fix: $500 - $1,200+

4-Speed Automatic Transmission

• Transmission Slipping: Gears slip out of engagement during driving, causing a loss of power. Symptoms include sudden acceleration or deceleration, delayed gear changes, and a burning smell. Solution: Rebuild or replace the transmission. Estimated Cost to Fix: $2,500 - $4,000+
• Torque Converter Failure: Internal components of the torque converter fail, leading to overheating and transmission issues. Symptoms include shuddering, delayed gear engagement, and slipping. Solution: Replace the torque converter. Estimated Cost to Fix: $1,000 - $2,000+

Suspension

• Leaf Spring Breakage: Overloaded vehicles or rough road conditions can cause leaf springs to break. Symptoms include sagging ride height, uneven suspension, and a rough ride. Solution: Replace the broken leaf spring. Estimated Cost to Fix: $500 - $1,000+
• Shock Absorber Failure: Worn or damaged shock absorbers reduce ride quality and handling. Symptoms include excessive bouncing, poor cornering, and decreased braking performance. Solution: Replace the shock absorbers. Estimated Cost to Fix: $300 - $600+

Electrical

• Battery Drain: A faulty alternator or excessive electrical load can drain the battery. Symptoms include difficulty starting the vehicle, dim lights, and electrical system malfunctions. Solution: Diagnose the source of the drain and repair or replace the affected components. Estimated Cost to Fix: $200 - $1,000+
• Starter Problems: Worn or damaged starter components (e.g., solenoid, brushes) can prevent the vehicle from starting. Symptoms include clicking noises, slow cranking, or no response from the starter. Solution: Replace or repair the starter. Estimated Cost to Fix: $300 - $600+

Exterior

• Rust and Corrosion: Exposure to moisture and road salt can lead to rust and corrosion on the body and frame. Symptoms include peeling paint, bubbling or scaling surfaces, and structural damage. Solution: Protect the vehicle with regular maintenance, such as washing, waxing, and rust-proofing. Estimated Cost to Fix: Varies depending on the severity of damage.
• Headlight Failure: Burnt-out bulbs or faulty wiring can cause headlight failure. Symptoms include reduced visibility at night and failed vehicle inspections. Solution: Replace the bulbs or repair the wiring. Estimated Cost to Fix: $100 - $200+

Interior

• AC Compressor Failure: A faulty AC compressor prevents the air conditioning system from cooling the cabin. Symptoms include warm air blowing from vents and increased fuel consumption. Solution: Replace the AC compressor. Estimated Cost to Fix: $1,000 - $2,000+
• Instrument Panel Malfunction: Faulty sensors or electrical connections can cause the instrument panel gauges to malfunction. Symptoms include inaccurate readings, flickering displays, or complete failure. Solution: Diagnose and repair the affected components. Estimated Cost to Fix: $500 - $1,500+

Summary
