2024 GMC Sierra 1500: problems, recalls and reliability

“While driving at highway speed in normal traffic, the upper front grill deflector detached from the vehicle and struck the windshield, cracking the windshield. This appears consistent with the defect that is the subject of Safety Recall N24290120.”Owner report · Structure · Jul 2026

“This vehicles top portion of grill trim is starting to come loose, as this is a safety concern while on the highway, I had another vehicle that the trim flew off completely, (same year and model) while i was on the highway. This could hit another vehicle if this happens, or god forbid a person who happens to be on a sidewalk. I looked into this and found that there is a recall for the same issue on 2022 models that has not been extended to the 2024 model (Recall N242490120). This recall should be extended to the 2024 models as this is a huge safety concern.”Owner report · Unknown Or Other · Jun 2026

“2024 GMC Sierra 1500 6.2 v8 had a full engine seizure while driving on the freeway. All prior recall actions had already been met (scoped and upgraded oil), within 60 days of dealership review the engine stopped working. Recall 25V-274 L87 Engine Loss of Propulsion. After a 5 hour event on the side of the road AAA towed the vehicle to the dealership where I was told it would be many months before this is returned. It took many weeks for GM to just review and approve any next service (engine needs). At this point I'm told there are 181 people also in line for an engine and they can't see where I might be in that line. So we wait.”Owner report · Engine · Jun 2026
