Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“Hello, I am writing to you today to inform you of a common and known issue with all GM ls engines that come with active fuel management (afm) or displacement on demand (dod). The lifters in the engine begin to fail somewhere after 40,000 miles - with this particular issue occurring in my own vehicle at just over 61,000 miles. If you were to google ls dead lifter , ls lifter failure or GM piston slap , the issues arises. I have contacted the Pontiac division at GM to complain about this, but they said that there is nothing they can do since the engine is no longer covered under their warranty . …”
