Your GMC’s battery is the heart of its electrical system, playing a crucial role in starting the engine and powering the on-board electronics. Recognizing the signs of a failing battery is key to avoiding unexpected breakdowns by getting quick battery service at your GMC dealer.
8 Signs You Need Battery Service From Your GMC Dealer
1. Slow Engine Crank
When you turn the key or push the start button, if the engine takes longer than usual to roll over or cranks sluggishly, it might be a sign of a weakening battery. This slow crank is often the first symptom that your battery is losing charge.
2. The Check Engine Light
Sometimes, a weak battery can trigger the check engine light on your GMC’s dashboard. While this light can indicate various issues, it’s wise to get the battery checked if it illuminates unexpectedly.
3. Swollen or Bloated Battery Case
Extreme temperatures can cause the battery case to swell or bloat. If you notice any deformation in the battery case, this is a clear sign that the battery life is compromised and replacement is necessary.
4. Battery Age
A car battery typically lasts about 3–5 years. If your GMC’s battery is approaching or has surpassed this age range, have it tested regularly and be prepared for a replacement.
5. Electrical Component Issues
If you start experiencing issues with electrical components in your vehicle, such as dimming headlights, flickering dashboard lights, or slow power window operation, these could be signs of a failing battery.
6. Corroded Connectors
Check the battery terminals for any signs of corrosion (white, ashy substance). Corroded terminals can lead to voltage issues and trouble starting your vehicle.
7. The Smell of Sulfur or Rotten Eggs
A damaged or leaking battery can sometimes emit a sulfuric or rotten egg smell. While bad smells are never something you want to detect in your engine, this is usually a serious sign that the battery needs immediate inspection and likely replacement.
8. Frequent Jump Starts
If you find yourself frequently needing to jump-start your GMC, it’s a clear indicator that the battery is losing its ability to hold a charge and needs replacement. However, if you find your car dying in the middle of a drive and a jumpstart won’t get it going again, the alternator rather than the battery is likely the issue.
Recognizing these signs can save you from the inconvenience of a dead battery at the wrong time. If you notice any of these symptoms with your GMC’s battery, visit Granite Automotive right away for a comprehensive battery check and replacement if needed. It’s always better to be proactive about your vehicle’s health.
