The 2018 Buick Enclave is one of the best-selling SUVs in the United States. It was designed to be spacious, comfortable, and high-tech. It is a good option for drivers with big families due to its seating capabilities.

Despite its high popularity, Buick Enclave has been plagued with numerous issues over the years. Among its biggest problems is the car battery. This article will show you the common battery problems that you might find in a 2018 Buick Enclave.

Battery corrosion

Firstly, the battery is prone to corrosion due to the high temperatures and humidity. Rust can be seen on the battery terminals, battery cover, and other parts of the car. Corrosion can also cause severe damage to the battery and might cause it to leak or even burst. This can result in significant damage to your vehicle. Check for any loose connectors that can attract sparks, which can lead to corrosion if this is left unchecked for long.

Swelling car battery

If the battery is swollen, it can be a sign of battery issues. The swollen battery can lead to the battery being unable to provide enough power. If this happens, the car might not start at all or only after long periods of time. This can be a serious problem and will require professional help to fix. This is usually due to overheating, so check what’s causing unnecessary heat and friction in your car.


A short-circuited battery can result in dangerous explosions or fire. It is important to keep an eye out for any spark that occurs on the battery terminals or around the engine compartment. This can happen when there is loose wiring in the car, loose cables, and even loose fuses that could lead to electrical short-circuiting.

Extreme temperatures

The battery might overheat due to the excessive temperatures. This can lead to serious problems and might cause your battery to burst. Aside from overheating, having your car and its battery exposed to freezing temperatures can be harmful in the long run, as well. The engine may take longer to start, and the battery will not be able to be fully charged as quickly as usual. As a solution, have a car battery charger at the ready for any incidents in the middle of the road.

Low on battery fluids

If the battery is low on fluids, it might not be able to provide enough power to start the car. In addition, the battery will not be able to fully charge as quickly as usual. This can lead to a malfunctioning or faulty car battery. In order to prevent this from happening, keep an eye out for any fluids that are low. Old fluids will also lead to rust, so it needs to be replaced periodically.
