NHTSA Complaint #11673122 — 2023 CHEVROLET SUBURBAN

Our Chevrolet suburban has 57,000 miles on it. We have started getting a check engine light and I’m getting code P1098 for the cooling control valve. This is a very common issue on these vehicles I’m noticing now. From what I’m reading in February of this year (2025) gm gave this issue an e code so these valves would no longer be covered pay the powertrain and they would now fall under emissions for a much shorter warranty coverage. This has been and ongoing issue since 2020. These valves are also commonly found to be on national back order causing long lead times and driving of the vehicles without properly functioning. GM knows these are and issue and shortening the warranty is not the fix. These vehicles weren’t bought with a short warranty and shouldn’t be able to be reduced to a short warranty.
