Why won't my vehicle start?
There are numerous reasons why a vehicle won't start. If it's related to the battery, the starter will generally not crank the engine. This is the telltale "click, click, click" you hear when you turn the key or push the start button that lasts for about 10 seconds. The battery voltage and charging information in the Driver Information Center (DIC) can also make you aware if the alternator is not charging the battery properly, or if a loose battery or starter cable is causing a problem.
Do I need to charge my battery after I jump-start my vehicle?
In most instances, driving will recharge the battery fully in 1-2 hours, unless there is an issue with the vehicle. If your vehicle does not restart after driving it, have it towed to your nearest Certified Service experts to have a diagnosis performed.
What are the main causes of automotive battery failure?
Batteries wear out over time, but issues such as improperly connected accessories, infrequent startup, hot temperatures, and high cranking currents caused by freezing temperatures (32 degrees Fahrenheit or colder) can lead to battery failure.
Can preventive maintenance improve battery life?
The best thing that you can do is have your Certified Service technician perform a test on your battery when you get your oil changed. This helps monitor the status of the battery and helps prevent you from being in a situation where your vehicle won't start.
How often should I change my battery?
Vehicle batteries last 3-5 years on average depending on a number of factors, including driving habits and climate. In general, warmer climates will shorten the life of a battery. Also, long periods of time spent in a discharged state tend to increase damage due to sulfation.
What if I'm not sure the problem is my battery?
Your Certified Service experts can give you a no-charge battery test to determine if your battery needs replacing or if there is an issue with another charging component.
