2018 Chevrolet Silverado 3500
Owners of the 2018 Chevrolet Silverado 3500 are looking to get a job done. After all, the newest lineup is labeled as giving customers, “towing confidence,” but that’s not entirely accurate. In fact, this heavy-duty Chevy truck has a faulty fuel system, defective engine and poorly-built structure.

NHTSA Complaints for the 2018 Chevrolet Silverado 3500
|Complaint Category||Number of Complaints|
|Engine And Engine Cooling:exhaust System:manifold/header/muffler/tail Pipe|
|Fuel System, Diesel|
Problems with the Fuel System
These massive pickups must carry fuel correctly or it could be a disaster waiting to happen. That’s exactly what tons of customers are complaining about.
Just read this Cars.com review. “First have had issues with diesel spitting back when filling. Second we have 13000 miles on it. The fuel filter needs replaced and now the brakes are soft. It is strong for power. Not happy the Navigation system was not and option for the work series. The display does not have night and day option. You can turn off the light but if you touch it you are back to the beginning.”
Notice there is a long list of complaints, but it starts with the fuel system. It’s not surprising to see that this defective system sparked a massive recall, including more than 18,000 models. It turns out the front fuel tank can overfill and cause a leak. NHTSA Campaign Number 19V088000 states that the force can actually cause a hole in the system. It’s pretty hard to have confidence while towing after noticing fuel dropping out of the truck.
Problems with the Structure
In addition, it’s clear that GM didn’t put a lot of care into the assembly and materials of this truck. The cheaply-made structure is something comparable to a budget-friendly compact car.
Another Cars.com reviewer expresses disgust by saying, “I had a 2013 Chevy loved it should have NEVER traded it in// Chevy and there CHEAP wax paint on frame … I wash my frames the car wash took the coating off the front frame now Chevy is to see it and the rust on frame and other parts.. They had to change ALL shocks already I spent only 2 months up north with the salt… and it started rusting with only 6000 miles and now I have around 13,500.I think we might have to move south for Chevy not to rust.”
They don’t make them like they once did, which is precisely what this owner found after trading the 2013 model for a newer 2018. Unfortunately, there are many more structure-related concerns beyond the rust. Service Bulletin #17NA258 talks about excessive wind noise coming from the side door glass region of the truck. So, when the pickup isn’t leaking fuel or rusting out, occupants are competing against loud wind noise. That might be fine for a convertible, but not a truck expected to provide “towing confidence.”
Problems with the Engine
If the engine under the hood is powerful and reliable, other aspects might be overlooked, especially when a customer needs maximum towing power. However, that’s not the case with the Chevy 3500HD. In fact, the engine is one of the most complained about parts.
One NHTSA complaint states, “The contact owns a 2018 Chevrolet Silverado 3500. The contact received notification of NHTSA Campaign Number: 19V328000 (Engine). The vehicle was taken to [dealer] to be serviced. The contact stated that the dealers did not complete the recall repairs as described in the manufacturer’s remedy. Disconnect instead of being replaced. The manufacturer was made aware of the failure and did not assist. The approximate failure mileage was 12,000 and continues to be ongoing mileage now – 15,000.”
The recall being referenced has to do with a short-circuit among the engine block heater that could increase the risk of fire. Dealers were expected to resolve the situation, but many of them have simply disconnected the engine block heater instead. Sadly, this isn’t an isolated complaint, but something found by owners across the nation. Considering the recall affects more than 300,000 trucks, it’s unclear how many are driving around with a disabled engine block heater at this time. Instead of caring about customer safety, GM is only concerned with the bottom line. Otherwise, the automaker would be getting involved in customer complaints and dealing harshly with these dealerships, but that’s not the case. The only confidence this truck brings is the peace of mind that comes from switching to a truck from the competitor and dumping Chevy entirely.

I have a 2018 Chevrolet Silverado 3500hd, that has had 2 recalls for faulty block heater, I have had it replaced twice, the first time I had it replaced, within a very short period of time a coolant low notification came up, we took it back to the dealer they reset the code and said the coolant was ok, we had the block heater replaced in Wisconsin, took it back to dealer in Wisconsin to have notification check where it was reset,we then proceeded to go back to Iowa where were living at the time, and the notice popped up again, so we took it back to the dealer where we purchased it. They told us the coolant reservoir had a sensor on the bottom of it that was bad, and that sensor could not be replaced we needed to replace the entire reservoir at our/insurances expense, even though the new about it and said it was pretty common, they knew what the problem was and what caused it, apparently when they changed the block heater air was left in the coolant system which caused the sensor in the reservoir to fail, now apparently we are experiencing the same thing with the second block heater recall replacement, i don’t quite know how to handle this, can’t help thinking that in the block heater replacement process that there aren’t instructions as to evacuating all air from the coolant system as this is obviously a common problem, and I would have thought there would have been a service order for this problem. Please email me thoughs or evidence of other owners having had this problem, Thank You
