“My 2021 Mercedes Benz GLE 350 got AC Conditioning Leak problem (blow hot air) , which could lead to a short circuit and even risk a fire. I checked with NHTSA recall history with this model, and found out 2020 and 2021 models had recall last year with AC issue, but my Vehicle was not included in 2023 recall (NHTSA campaign number: 23V-177). I believe manufacturer was aware of this model AC issue from manufacturing defect, but inappropriately set the range of recall. Please investigate this issue.”
