What are a few common electrical issues that owners may encounter with the 2012 Nissan Altima?

If there's a problem with the alternator in your 2012 Nissan Altima, there are some clear signs to watch out for. The first indication is a dead battery. Although a dead battery doesn't necessarily mean the alternator is faulty, a malfunctioning alternator is often the culprit for a dead battery. If the battery hasn't completely died, you may observe dim or erratic behavior in the instrument panel, possibly accompanied by flickering and noise due to fluctuating power supply. The cost of replacing the alternator, including parts and labor, typically ranges from $300 to $500, which may seem a bit expensive, but it's a necessary fix. Delaying the replacement can lead to further damage and a likely replacement of the battery, which could cost an additional $100. If you opt for a DIY replacement, you'll need to unbolt the clamps and remove it, but fortunately, it's conveniently located at the front and easily accessible.
