What Happens If You Don't Start Your GMC Car For A Long Time?

Cars, especially those like your GMC, are designed for regular use. However, sometimes life gets in the way, and your vehicle may sit idle for weeks or even months. Whether you're traveling, have another vehicle for daily use, or are simply not driving as much, letting your GMC sit unused can lead to various issues. If you don't start your vehicle for an extended period, there are several things that can go wrong with the engine and its components. To keep your GMC in peak condition, it's important to understand the risks involved and how to mitigate them. GMC Danvers can provide helpful tips on how to care for your vehicle during long periods of inactivity.

Battery Drainage

One of the most immediate and common issues with not starting your car regularly is battery drainage. Car batteries are designed to maintain a charge over time, but if a vehicle isn't started, the battery can lose its charge. Typically, a car battery will start to degrade after about two weeks of non-use. If left long enough, you may come back to a dead battery that will require a jump start or even a replacement. To avoid this, consider disconnecting the battery when storing your vehicle for a long time, or using a battery tender to maintain its charge.

Fuel Problems

Another issue you may encounter if your GMC sits for a long period is fuel degradation. Gasoline contains compounds that can break down over time, especially when exposed to air. After a month or more of inactivity, the fuel in your vehicle can begin to separate, which may lead to the formation of gum and varnish that clogs fuel injectors and lines. This could result in starting issues or poor engine performance when you eventually drive the vehicle. To prevent this, it's a good idea to use a fuel stabilizer if you plan on leaving your vehicle idle for more than 30 days.

Tire Damage

When your car remains stationary for extended periods, the tires can develop flat spots. This happens because the weight of the vehicle is concentrated on the same parts of the tires for too long, causing the rubber to weaken and flatten out. In extreme cases, this can lead to permanent damage, requiring tire replacement. To avoid flat spots, it's a good idea to elevate your GMC on jack stands or move the car periodically, if possible.

Fluid Breakdown

Your vehicle's fluids, including oil and coolant, are designed to lubricate and protect engine components. However, if your GMC isn't started for a while, these fluids can begin to break down and lose their effectiveness. For instance, engine oil can lose its viscosity, which can increase friction and cause engine wear. Similarly, coolant can degrade, reducing its ability to prevent overheating. It's crucial to check and replace any fluids that may have become contaminated due to inactivity.

Brake Issues

The brakes are another area where inactivity can cause problems. When your car isn't in motion for a long period, the brake pads and rotors can begin to rust, particularly if the car is stored in a humid environment. This can lead to squealing, reduced braking performance, or even brake failure in extreme cases. To avoid this, consider driving your car around the block periodically to keep the brake system active.

To keep your GMC in optimal condition, it's important to take steps to prevent these issues if you anticipate not using your vehicle for a while. For personalized advice and maintenance solutions, visit GMC Danvers to schedule a consultation with one of our experts.
