Summary: The 2024 GMC Sierra 1500, while offering many appealing features, has already shown some common issues. Engine problems, particularly AFM lifter failure in the V8 engines and potential turbocharger issues in the 2.7L turbo, are potentially expensive and should be carefully considered. Electrical gremlins, like infotainment glitches and sensor malfunctions, are also relatively common. While some issues can be resolved with software updates or minor repairs, others may require significant investment. Prospective buyers should be aware of these potential problems and factor them into their purchasing decision. Monitor reliability trends as more data becomes available throughout the model year.
