10. Exhaust System Corrosion: Exhaust leaks can lead to poor engine performance and emissions issues. Repair costs: $200 – $1,200. Common occurrence after 70,000 miles.

Engine Issues

Engine-related problems are among the most critical issues that can arise in a vehicle. Symptoms often include unusual noises, vibrations, loss of power, or difficulty starting. Common engine issues include:

1. Oil Leaks: Often caused by worn gaskets or seals, oil leaks can lead to engine damage if not repaired. Look for puddles under the car. Average repair costs: $150 – $1,000.

2. Timing Belt Failure: A broken timing belt can cause significant engine damage, leading to a complete engine rebuild. Symptoms include unusual noises and a non-functioning engine. Repair costs: $500 – $2,000.

3. Spark Plug Problems: Faulty spark plugs can result in misfires, reduced fuel efficiency, and performance issues. Symptoms include rough idling and sluggish acceleration. Repair costs: $100 – $300.

4. Fuel Injector Failure: Clogged or malfunctioning injectors affect performance and fuel economy. Symptoms include rough running and poor acceleration. Repair costs: $150 – $800.

5. Head Gasket Failure: This serious issue can lead to overheating or coolant mixing with oil, requiring expensive repairs. Symptoms include white smoke and engine overheating. Repair costs: $1,000 – $2,500.

Identifying these symptoms early and addressing engine-related problems promptly is crucial to preventing more significant issues down the line.

Transmission Issues

Transmission problems can significantly affect vehicle performance and drivability. Symptoms may include strange noises, slipping gears, or delayed engagement. Some common transmission issues include:

1. Fluid Leaks: Low transmission fluid can lead to shifting problems or overheating. Keep an eye out for red spots under the vehicle. Repair costs: $100 – $500.

2. Failed Torque Converter: This component can malfunction, causing engine performance issues and overheating. Symptoms include slipping and shuddering during acceleration. Repair costs: $400 – $1,500.

3. Shifting Problems: Difficulty shifting gears, particularly in automatic transmissions, can be a sign of low fluid levels or worn components. Repair costs: $200 – $1,500.

4. Transmission Control Module (TCM) Failure: This electronic component can fail and cause erratic shifting. Symptoms include delayed or harsh shifts. Repair costs: $300 – $1,200.

5. Clutch Wear in Manuals: Over time, clutches can wear out, leading to slipping and failure to engage properly. Repair costs: $500 – $2,000.

Regular maintenance and timely repairs of transmission issues can prevent more extensive (and expensive) repairs.
