Most Common Problems: 2018 Chevrolet Silverado 2500/3500 Heavy Duty
When it comes to heavy-duty trucks, the 2018 Chevrolet Silverado 2500 and 3500 models have earned their reputation as reliable workhorses. However, like many vehicles, they aren’t immune to certain issues that pop up over time. Based on customer feedback and data from RepairPal, here are three of the most commonly reported problems with these models.
One of the more frustrating issues is an erratic speedometer. This typically happens due to an electrical glitch or a problem with the speed sensor. These sensors can sometimes get damaged during regular maintenance or from debris hitting the vehicle. While you might not always see the damage, you’ll certainly notice when your speedometer starts behaving unpredictably.
Fixing this issue can vary depending on what’s causing it. Sometimes, a straightforward electrical adjustment can solve the problem, while other times, you might need to replace the entire speedometer system. If the issue lies with the speed sensor, replacing the wheel speed sensor is often the best course of action.
Another common complaint involves the fuel level sensor failing. When this happens, you won’t be able to tell whether your tank is full or nearly empty. Mechanical failure is usually the culprit here. To resolve this, you’ll likely need to replace the fuel level sensor. For older or higher-mileage vehicles, it might even be necessary to replace the entire fuel pump module.
The third issue many owners encounter is a persistent "4WD Service" message on the dashboard. This warning light can appear for several reasons, so it’s important to have it checked out promptly. Often, the problem stems from a faulty switch, though it could also indicate an issue with your four-wheel-drive system or an incomplete gear shift. Either way, ignoring this message could lead to bigger problems down the line.
