2015 Chevrolet Silverado 1500: check engine light

Filed Sep 15, 2026 · Engine, Transmission · IN

I am filing this complaint regarding a serious engine lifter/Active Fuel Management (AFM) failure in my 2015 Chevrolet Silverado 1500. The vehicle experienced a lifter failure that caused significant engine problems and created a potential safety concern while driving back from shopping: loss of power, engine misfire, severe shaking, ticking, check-engine light, stalling, inability to maintain speed, etc. The vehicle had approximately 200k miles at the time of the failure. The vehicle was inspected by a local mechanic, which diagnosed the problem as collapsed/failed lifter. The repair required/will cost approx. 3k or more estimated My concern is that this does not appear to be an isolated failure. Other owners of 2015 Chevrolet Silverado 1500 trucks equipped with GM's Active Fuel Management system have reported lifter failures, including failures resulting in engine damage and sudden loss of engine power or propulsion. A sudden lifter or related engine failure can create a significant safety hazard, particularly when it occurs at highway speeds, while merging into traffic, crossing an intersection, or in another situation where the driver depends upon the engine to maintain acceleration and vehicle speed. I am reporting this in hopes that GM can be held accountable as they knew about these defective lifters but did nothing but hide it.

While driving at 55-60 mph on Saturday, [XXX], the vehicle made a distinct engine sound and lost power, but continued to run with a pronounced misfire, and a ‘check engine’ light came on. Our safety was put at risk because we were merging into high speed traffic and I had to abruptly slow and move as far out of the travel lane as possible. I had the vehicle towed to Champion Chevrolet in Reno on Wednesday October 16 for evaluation. The mileage in was 44,252. I was told that the camshaft and some lifters had failed, and I opted to have the engine replaced with a remanufactured unit at the total cost to me of $14,660. I picked the vehicle up on 10/28/2024 with 44,259 odometer miles. I have since learned on the internet that this particular ‘Active Fuel Management (AFM)’ failure is known to Chevrolet corporate office and is the subject of a class action lawsuit against Chevrolet. I have also learned that there is the possibility of repayment to affected owners in early 2025. I am submitting this letter to bring my situation to your attention so that I am included in any list of owners that may be reimbursed as a result of this known engine issue.

The torque converter with the 6L80 transmission went and destroyed the transmission in my 2015 Silverado. Which is going to cost me thousands of dollars to fix. With the 10's of thousands of people affected, Chevy should of done a recall on the torque converter and/or transmission. There were no signs/symptoms, the truck started shaking like I was driving over rumble strips, no check engine light. I was able to get it to a mechanic immediately and it sits there unusable at this time.

I bought this vehicle last November from Shea. When we bought the truck we noticed the check engine light, but was told that we would have to bring it back in for inspection. The last vehicle we bought from Shea it had a 30 day return and it would fix any problems. Not so with this time. So, we purchased a Platinum warranty which was a little above $2K and we believed would cover these issues. That was not the case. We had a friend of ours who is a GM Mechanic look it over and told us that it needed a high pressure fuel pump. So when I brought the vehicle in on January 22nd I told the service person at the desk that we had a platinum warranty and told him that I had a GM technician tell me that it needed a high pressure fuel pump. After sitting for six hours he comes out and tells me that I needed a high pressure fuel pump and tells me it will cost me $1400.00+ to have it fixed and it would not be covered by my warranty. And then tells me that the work they did today would cost me $150.00. I told him when I came in what the problem was. I understand that they need to do their own diagnostics, but why didn't they tell me that the part would not be covered by the platinum warranty. We paid $23K for the truck, plus an additional $2k+ for the warranty and now an additional $1,400.00-$1,500.00 for the fuel pump. So, yes we are not happy and will give a second thought to ever using Shea again. I understand that this memo will not change things, but I want you to understand that prior to today's fiasco I have told friends that I would recommend Shea when looking for a vehicle. Now I would not recommend Shea to any of our friends. Sorely disappointed! To go along with the previous text, when I purchased the 2015 Z71 Silverado the key FOB fell apart so I purchased two (2) new ones at a cost of $225 each so that I could start my vehicle on cold winter days. So far, that was a waste of money a money also because the check engine light and the high pressure fuel pump
