2018 Chevrolet Silverado 1500: misfire or rough idle

Filed Dec 14, 2025 · Engine · VA

Since purchase in 2018, my pickup truck has had a ticking and banging sound which includes rough idling and a check engine light. During routine maintenance, oil changes, etc. I have continued to ask about the noise but GM technicians have said nothing is wrong. In November 2025, i took the truck to a local shop for an oil change and that’s when I learned it has lifter issues. Upon investigating whether other Chevy Silverado truck owners are experiencing the same thing, I’ve learned about various recall and extended warranty programs offered by General Motors. I’m wondering when or if my 2018 Chevy Silverado might be included in a recall or could i be offered an extended warranty?

I purchased my truck in December 2018 which is a 2018 Chevrolet Silverado 1500 4x4 crew cab automatic from Servco Chevrolet Dealership in Waipahu, Hawaii and making monthly payments for my truck February of 2019 truck runs good and purchased the warranty also had my oil and service changed when time is due which I always kept up. [XXX] and mileage was 40k while leaving work to go home at a stop light was red once turned green I pushed pedal to go and truck just changed noise tone started to run like rough idle, loud tapping noise coming from the engine, shaking and check engine light came on almost causing me to get into an accident. I pulled on the side and checked what was going on and heard the tapping noise from the motor. So I made an appointment with service department with Servco Chevrolet Dealership where i bought my truck from and spoke with the service tech for my truck to go in for repairs due to issue. It took 2 to 3 weeks for repairs to be complete and service tech informed me that I'm not the only person to have that issue which had to do with the lifters and camshaft with these motors but GM never came out with any recalls due to how much people has the same motors with the same issue. So luckily it was still covered under warranty but said the problem might come back and would just replace the faulty lifters and camshaft. So in August of 2023 my truck has the same issue but wasn't covered under warranty anymore and mileage is 61k and missed the warranty repairs that was for the lifters which I got it scanned cause check engine light and same issue and code was P0016. So I called Servco Chevrolet dealership in waipahu again and spoke with the service technician which he told me I just missed the coverage of the warranty repair and only way to get it fixed I would have to bring it back for them to scan and roughly would range from 4k to 8k to get it fixed. So my truck is parked in my garage and hasn't been moved but paying for truck. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT

On 4/18/25 I was driving to work and was about 2 miles from work when I started to get all kinds of faults displaying on my screen. The engine started to run rough; it sounded like it was not running on all cylinders. After work I drove it straight to the maintenance shop I have been using. They informed me that a lifter failed and went into the cam shaft and created all kinds of metal. I was informed that this was the second Chevrolet Silverado they have had this problem and replaced the engine.

I was driving on the interstate and then all of a sudden my vehicle started shaking while driving and by the time I got home in less than 15 miles, the truck was producing huge clouds of smoke out of the exhaust. I took it to a dealership and it was determined the lifters were bad, less than 6 months after I paid off my vehicle and the extended warranty expired. In repairing the lifters it was determined there was a misfire in cylinder 6 which in conjunction with the lifter failure, it damaged rods and pistons to such an extent full engine replace was deemed necessary. I had every maintenance and inspection done on time since the purchase of the vehicle by a local Chevrolet dealership and there apparently was no warning or concern that my lifters were going to imminently fail and/or cause extensive engine damage. My truck was in the repair shop for nearly a 1 year while I waited for a new engine Chevrolet agreed to pay for half of an engine even though I was out of warranty by a few months, but I was under the mileage on the warranty by 30k miles. The truck was not heavily used. Most miles were highway interstate miles from long road trips, but the vehicle largely sat undriven most days of the week for a couple years leading up to the engine failure.

2 separate lifter failure incidents at 61,000 miles. One failure, happened on a busy interstate, while flowing with the speed of traffic. Truck started to misfire, jerk and blow smoke. I had trouble getting to shoulder of highway to get out of the speed of traffic. The issue was a collapsed AFM lifter # 6. All the lifters were replaced on the passenger side on my dime. 450 miles later, I had to limp again to the repair shop that performed the previous repair to find AFM lifter # 4 failed this time. GM has been knowing about these lifter issues for many of years and this is a safety concern while on busy highways.

While driving my 2018 Silverado, the 5.4L, 327c.i. engine began idling very rough, shaking and periodically stalling. The check engine light began blinking and it threw codes PO308 & PO301. After compression test & new plugs/wires, it was found that the injectors had open circuits on injector #'s 1 & 8. The only way to replace the injector is through the bank. In this case both banks 1 & 2 were affected. Cylinder #1 is through bank #1 & cylinder #8 is through bank # 2. After removing the intake manifolds and injectors, it was found that the injectors were not providing fuel to the engine causing a misfire on 2 random cylinders #1 & #8. Called the dealer to order parts and discovered they have already been superseded. Original part# is 12698484 and it has been superseded by part# 12710481. Then injectors were replaced & new intake manifold gasket installed w/ proper torque. After repair completed and engine tested, the problem was resolved. Repair shop's invoice will be attached for reference.

Our 2018 Chevrolet Silverado 1500 was purchased new and only serviced at Chevrolet dealerships. While on vacation we were driving on a 3-lane paved road and then engine started knocking for a few seconds and then a chime could be heard and the check engine light came on. The vehicle lost power and the vehicle was difficult to control. We were fortunate that other vehicles were able to avoid us since our truck slowed quickly (without the brakes being applied). The vehicle had to be towed to a local Chevrolet dealer for diagnostics. The dealer found that the hydraulic lifters on the right bank of the engine collapsed (resulting in a misfire) and there was extensive engine damage. The vehicle was equipped with a 5.3l engine with AFM/DFM (cylinder deactivation). Mileage was 64,562. Vehicle was repaired with "upgraded" valve train parts from General Motors as this failure mode seems to be somewhat common in AFM/DFM engines (can find class action information during web search).
