Buick is an American car company which was founded in Detroit, Michigan in 1903. Buick became one of the largest and most profitable automobile companies by the time it was acquired by General Motors (GM) in 1908. Buick is known for building cars that are reliable and well-designed. However, some of its cars have been known to have some problems over the years.

The 2017 Buick Enclave is one of the most reliable cars that you can buy today. However, there are still some Buick Enclave problems which need to be addressed before you buy one. One of the common problems is with the gas gauge. Here’s some possible signs of issues in your Buick Enclave’s gas gauge:

Check The Wirings

The first thing you should do is to check the wiring connections. The wiring connections are sometimes loosened or corroded. You may be able to tell that this damage has happened if the fuel gauge gets stuck at one place despite the fuel recently being refilled.

For this case, check for corrosion and clean the connections if needed. That should fix the problem.

Look For Blown Fuses

If the problem persists, then you should check for blown fuses. Fuses are one of the easiest parts to replace, so you can check them easily. This is particularly likely to be the source of the problem if multiple gauges are showing the same malfunction. So, check the fuse box under the hood for blown fuses.

Check The Fuel Pump

A common cause of fuel gauge problems is a faulty fuel pump. This is very likely to be the case if the fuel gauge only shows half of the tank’s capacity. You can check this easily by checking for leakage at the bottom of the tank, or by turning on the ignition and watching for leaks at that spot.

If you see no leakage, then you should have a look at your fuel pump to make sure it’s not broken. Even with no leaks, if the problem persists, then it’s likely that your fuel pump is bad and needs to be replaced.

Test The Gauge With a Multimeter

The best way to test the gauge is to use a multimeter. A multimeter can check the electrical resistance of the wires, which will tell you if they are corroded or not. If the resistance is lower than what it should be, then that is a sign that there is corrosion on the wires.

In this case, you should check for corrosion and clean the connections if needed. That should fix the problem.

Avoid Overheating

Overheating is one of the most common causes of gauge problems. A fuel pump can overheat, and this can cause it to work less efficiently. So, if you notice that the gauge is working more slowly than usual, then this is a sign that your fuel pump may be overheating. You should take measures to prevent this from happening by avoiding excess speed and heat.
