Engine and starting problems

• Engine stalling and not starting: This can be caused by a failed alternator, faulty starter, a dead battery, or issues with the engine control module (ECM). 
• Engine overheating: A faulty thermostat, radiator fan, or coolant leak can cause the engine to overheat. 
• Engine failure: In some cases, the engine may fail due to a faulty PCM (Powertrain Control Module).
• Misfires: Worn spark plug tube seals can cause misfires, poor fuel economy, and rough running. 

Transmission issues

• Erratic shifting: The automatic transmission may have problems with rough or erratic shifting. 
• Stuck in gear: The transmission can get stuck in a lower gear. 
• Delayed engagement: Delayed shifting, especially between park, drive, and reverse, can occur due to internal component wear or control system issues. 

Electrical and other systems

• Faulty TIPM: A defective TIPM is a known cause of various electrical problems, such as the engine not starting or stalling, dimming lights, and the battery light coming on.
• Alternator failure: The alternator can fail, leading to dimming lights, slow cranking, and a dead battery.
• Electrical issues: Other electrical problems may include the radio and remote keyless entry not working correctly.
• Knocking AC compressor: Owners sometimes report a knocking noise coming from the AC compressor.
• Wet carpet: A clogged evaporator drain can lead to wet carpets inside the car. 

Suspension and brakes 

• Faulty rear suspension: The independent rear suspension, with its multiple links and bushings, is prone to failure. It is recommended to inspect and replace these components if necessary. 
• Squeaking brakes: Squealing brakes are a common complaint reported by owners. 

Interior and body

• Heater failure: The heater core is a weak point and can plug up, resulting in heat only on one side of the car.
• Interior wear: The plastic trim inside the cabin may break, and the edges of seats can show wear.
• Chrome peeling: The chrome on interior door handles can peel, becoming a potential hazard if the edges are sharp.

Is the 2008 Dodge Avenger a good car?

A 2008 Dodge Avenger can be considered a good car for its affordable price and sporty styling, especially if it has the V6 engine, but it has known issues that can make it a poor choice if not well-maintained. Common problems include potential transmission failures, especially in the V6 models, and heater problems that can be expensive to fix. However, some owners praise its comfortable ride and features, and it has an above-average reliability rating from some sources when properly maintained.
 
Pros

• Affordable: It was a relatively inexpensive vehicle when new and has a low used car price today, making it a budget-friendly option. 
• Sporty design: Many owners like its aggressive exterior styling. 
• Available all-wheel drive: A rare offering in its segment that can be helpful in some climates. 
• Good performance (with V6): The 3.5L V6 engine provides quick acceleration, although the base four-cylinder is considered weak. 
• Comfortable: Many owners find the ride comfortable with good legroom. 
• User-friendly features: Some models include features like a heated/cooled cup holder and an infotainment system with a hard drive. 

Cons

• Transmission issues: Transmissions in both 4-cylinder and V6 models are prone to premature failure, with the V6 being more susceptible. 
• Heater problems: A common issue is the heater only working on the driver's side, which is costly to repair. 
• Other common problems: Other potential issues include a failing blender actuator, warping brakes, and problems with the paint. 
• Lower-quality interior: Some reviews note that the interior materials are not as refined as competitors, and the ride can be stiff with a noisy suspension. 
• Recalls: The 2008 model has had multiple recalls. 

Recommendation

• Consider if: You are on a tight budget and can find a well-maintained example, ideally with the more powerful V6 engine, and are willing to take on the potential for more significant repairs down the line.
• Avoid if: You want a car with minimal repair headaches or are looking for a vehicle with a high-quality interior and a refined driving experience.
