Alternator Failure
A faulty alternator can fail to recharge the battery, leading to battery drain. Repair costs range from $300 to $700 for replacements.
Starter Motor Issues
Difficulty starting your vehicle may suggest a failing starter, typically costing $150 to $500 in repairs.
Fusible Links/Relays Failure
Electrical components may fail, causing various systems to malfunction—repairs range from $50 to $300 depending on the affected areas.
Additional Technical Problems
Aside from engine and transmission issues, additional technical problems can arise affecting overall vehicle performance and functionality.
Fuel Injector Failures
If the vehicle runs rough or has poor acceleration, clogged fuel injectors may be the target. Replacement costs range from $300 to $800.
Cooling System Problems
From hoses to the radiator, any failure in the cooling system can lead to overheating. Repairs can vary from $100 to $1,500 based on the component requiring service.
