Alternator typically lasts about seven years, or about 100,000 to 150,000 miles, adds Waits. Some mechanics, though, say they typically see alternators last about 80,000 miles. Several factors can affect how long an alternator lasts, including the quality of the part, conditions in which the car is driven and how many electronics are being used inside the car.

 

Signs your alternator is failing (2012-2021 Jeep Wrangler Alternator Replacement)

In some cases, when an alternator is about to die, there are a few warning signs.

Identifying what those signs are can signal you to have it checked by a mechanic, which can save you from being stranded on the road.

One of the most common signs of a faltering alternator is when the headlights start pulsating at night, from dim to bright.

Some alternators may stop working if they are charging several electronics at once.

Other signs may include an electrical burning smell coming from the alternator, or the battery, the alternator warning light or other dashboard warning lights turning on.

A struggling alternator may also cause your car radio or other electrical components to work intermittently, or cause a squealing noise in your car’s engine.

 

Maintaining your alternator (2012-2021 Jeep Wrangler Alternator Replacement)

When the alternator goes bad, the electronics try to draw all of their power off the battery, which can cause the battery to die as well. That’s why, oftentimes, the alternator, not the battery, is the problem in the first place.

Most reconditioned alternators come with at least a one-year warranty, while some come with a warranty for up to three years. Some new alternators may carry a limited lifetime warranty. Check with your mechanic to learn how long the warranty is and what it covers.
