Most Common Problems: 2018 Chevrolet Silverado 2500/3500 Heavy Duty

The Chevrolet Silverado is one of the most popular trucks on the market. It's also prone to some common maintenance complaints. Here are the three biggest problems found in the 2018 Chevrolet Silverado 2500/3500 Heavy Duty based on the number of customer complaints RepairPal has recorded.

Problem 1: Silverado erratic speedometer

Most likely cause: The most common cause of an erratic speedometer is an electrical issue. There could also be a problem with the vehicle's speed sensor, which can become damaged during routine repair work or as the result of damage from road debris. You may not notice the road debris, but you'll definitely notice when your speedometer starts acting weird.

Solution: Depending on the cause, the solution to fixing an erratic speedometer could range from a simple electrical fix to taking out and replacing the whole system. If the cause is the speed sensor, then you'll probably need to have the wheel speed sensor replaced.

Problem 2: Silverado fuel level sensor failure

Most likely cause: If your fuel level sensor isn't working, it's impossible to know if you have gas in the tank or you're running on E. The most likely cause of this malfunction is a mechanical failure.

Solution: You'll need to have your fuel sensor replaced in order to correct the failure. In some cases, especially with older or high-mileage vehicles, you may need to replace the entire fuel pump module.

Problem 3: Silverado 4WD service message won't turn off

Most likely cause: Anytime you see a message show up on your dashboard, you should bring it in for maintenance just to make sure it isn't anything serious. A lot of customers report that the 4WD service message is constantly displayed on their dashboard, which is likely the result of a faulty switch. You might also have an issue with your 4WD, which you should get checked out pronto. Finally, the cause could be an incomplete shift in gears, which could lead to major problems down the road.

Solution: The solution will depend on your exact cause. A service technician can run a scan to determine the problem. The switch may need to be replaced, which is generally a quick and easy fix.
