Frequently asked questions about car alternator repairs

Driving with a bad alternator isn't a good idea. A failing alternator can make the battery drain fast, leading to a breakdown. Electrical parts may also stop working, which can be unsafe. It’s best to get the alternator checked and fixed or replaced as soon as you can.

When the alternator fails, the battery won't charge and will drain. This can make the car stall and prevent it from starting. Electrical parts like lights, radio, and power windows may stop working. Get help from a mechanic right away to avoid more damage.

Alternator reconditioning means fixing an old alternator by replacing worn-out parts. This can be cheaper than buying a new one, but it may not last as long as a new alternator.

The cost of an alternator varies by the type of car and the quality of the alternator. To know exactly how much, you should talk to your local mechanic.

Yes, alternators can be repaired if the damage isn't too bad. If the alternator is very damaged, it may be better to replace it.

Replacing an alternator is often worth it if the alternator is old or very damaged. A new or rebuilt alternator can work better and prevent future problems. Talk to a mechanic to help make the best choice.

Alternators usually last between 80,000 and 150,000 miles. But it can vary based on where and how you drive, and maintenance. Regular check-ups and fixing problems early can help it last longer.

Some alternator repairs or replacements may be covered under the car’s warranty, especially if the car is still new. Check your warranty details or talk to your mechanic to see if it's is covered.
