NHTSA Complaint #11658841 — 2007 CHEVROLET SUBURBAN

As the current investigation is going for the General Motors engines 2014-2025 5.3L and 6.2L for AFM/DFM. The same is happening with 2007 - 2014 5.3L engines with DOD. I had a 2014 Chevy Suburban with the 5.3L I had to rebuild the passenger side due to a DOD lifter failing. My current, 2007 Suburban is starting to make a DOD lifter tap, again on the passenger side. I will be getting a full rebuilt engine with the DOD system deleted to prevent this in the future. Hundreds have had this happen in the car forums and I can not imagine how many have encountered the same issue but do not say anything due to chalking it up to mileage, age of the vehicle, or just accepting the failure by design. Most are simply taking it on the chin; paying out of pocket or doing the work themselves to repair, delete, or modify the engines. I understand there is time and the age of the vehicles against these claims, but acknowledgement and shedding light on this known issue from General Motors will help just as much.
