2015 Chevrolet Suburban Engine Problems

Replaced lifters 1,3,5,7 and added automatic fuel mgmt system bypass chip after the vehicle went into limp mode ON THE HIGHWAY. Ran for less than 2000 miles and those same lifters failed a second time and had to be replaced AGAIN. The last incident occurred after about 200 miles and had engine failure, limp mode with multiple sensor failures in the middle of the road in the dark. Limited ability to move it safely off the road.

I have a 2015 Chevy Suburban with a 5.3L v8 motor. At 123,067 miles I lost the lifters in the number 7 cylinder due to the Active Fuel Management (AFM) system. This is an ongoing issue with Chevy motors from2014 to 2021. There is currently a Class Action Law Suite. I am hoping the NHTSA will issue a recall. This repaid cost me $4,000.00 to repair.

The contact owns a 2015 Chevrolet Suburban. The contact stated that while driving approximately 40 MPH, the vehicle lost motive power, with an abnormal clicking sound coming from the engine compartment. The vehicle was taken to an independent mechanic where it was diagnosed that the hydraulic lifters needed to be replaced. The vehicle was not repaired. The vehicle was then towed to the residence. The vehicle was towed to a dealer where it was diagnosed that the hydraulic lifters needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was approximately 91,800.

The # 7 cylinder valve lifter in the 2015 Suburban engine fails when accelerating in certain situations. This has happened to this vehicle twice at and expense of rebuilding the engine. The in both cases the vehicle was accelerating into fast moving traffic. When the lifter fails the engine loses power and no longer accelerates which requires swerving out of traffic, back to the shoulder to not get rear-ended by on-coming traffic. The problem was confirmed and the service provided indicated that this was a significant issue with this particular engine. Basically, it happens to many of these vehicles. The engine has been rebuilt twice while I have owned it. When the lifter fails the check engine light comes on. These failures occurred on September 24, 2021 and again on September 9, 2023.
