Could General Motors be on the verge of another lawsuit?

A recent survey from Consumer Reports magazine outlines major reliability concerns in all of GM's pickup truck engines.

It comes as a shock to some and no surprise to others that General Motors is in the hot seat again with yet more mechanical issues that generate concern on vehicle reliability. General Motors has been on the front of numerous lawsuits this year, with a few springing to mind. GM's latest lawsuit involved LG Electronics and consumer fraud on the 2021 Chevrolet Bolt. Another on the lifter valves on two V8 engines.

This week, a survey from Consumer Reports has highlighted major reliability concerns for both the Silverado and Sierra's engines. According to GM Authority, 4 percent of Chevy Silverado and GMC Sierra owners reported some kind of major engine issue, including full engine replacements, as well as cylinder head-related issues. Major engine issues include an engine rebuild or replacement, cylinder head problems, head gasket problems, turbocharger or supercharger problems, and timing chain or timing belt problems. The truck received a 1 out of 5 stars on reliability for the 2021 model year. The 2022 survey data has not yet been collected.

Four percent may not appear as an astronomical number or even enough to create a lawsuit, but issues surrounding GM's V8s are not new. Specifically, lifter valve issues with the 5.3-liter V8 date back to when it was introduced in 1999. While improvements have been made, consumers are still fronting major issues that pose long-term reliability concerns.

As GM pursues a transition to producing only electric vehicles the concerns of reliability and safety are among the greatest faced by consumers. While the outstanding issues present in GM's gas-powered engines will soon be nullified by EVs, the emergence of new issues involving electric vehicles could create future issues with the brand and possibly lead to additional legal consequences for the company if not resolved accordingly.

  • I worked at a Chevrolet dealership and did probably 10 lifter jobs on brand new trucks in about 3 months, the Duramax's have fuel injector issues every 30,000 miles or so. I don't think EVs will solve this problem it will just make people's daily life and work harder or impossible.

  • GM Days are gone and 2008 proved it so I wouldn't be surprised if this shuts them down.

  • the issue with collapsed lifters is only on the engines with cylinder deactivation the other lifter issue they have had on and off since the LS was introduced is with the rollers coming apart and destroying the cam, both these issues have seemed sporadic though. we'd have a couple of model years where it was an issue and then it would go away and then a few years later they would start having the issue again with no apparent design changes, I think it's issues with certain parts suppliers making low quality parts more than a design fault, GM needs to stop getting parts from the lowest bidder.

    • Yeah, I figured it was only present on the engines with cylinder deactivation. Consumer Reports only had limited data as this was a consumer response survey.

      And, I do agree with the fact that it's cheap parts causing the issue. I've owned...

  • Given GM's track record with EVs, I don't think those will be any more reliable lol
