Signs You Might Have an Alternator Problem:

Your vehicle’s charging system—which includes the alternator, battery, ignition, starter, and computer system—should be checked at least once a year to ensure everything is functioning correctly.

What Does an Alternator Do? The alternator generates the electricity your vehicle needs while the engine is running. It charges the battery and powers your lights, radio, ignition system, and other electronics. A bad alternator can drain the battery quickly, leaving you stranded.

Common Alternator Issues:

  • Dim Lights – Alternator may not be generating enough power.
  • Battery Light On – Your system voltage is too low.
  • Dead Battery – Alternator may not be recharging it.
  • Burning Smell – Belt may be slipping or worn.
  • Starting Trouble – Alternator isn’t supporting the ignition system.

Does Your Transmission Need Service or a Rebuild? A complete transmission failure can leave your vehicle undrivable and result in a high repair bill. To avoid that, it’s important to understand the early signs of transmission trouble. Here are two common indicators every driver should watch for:

Check the Transmission Fluid - Regularly inspecting your transmission fluid can help you catch problems early. Healthy fluid should be reddish, clear, and have a slightly sweet smell. If it’s brown, thick, or has a burnt odor, it’s time for a transmission change?

Also check the transmission fluid level using your vehicle’s dipstick. Low levels often indicate a leak — transmission fluid doesn’t burn off like motor oil. Look for spots under your vehicle or signs of fluid around the transmission housing.

Poor Transmission Shifting or Slipping Gears - Your car should shift gears smoothly and without hesitation. If you experience slipping, delays, or jerky transitions, especially when shifting from Park to Drive or while accelerating, your transmission may need attention. Manual and automatic transmissions show symptoms differently, but both require immediate inspection when performance drops.
