| Defroster/defogger/hvac System Condensor/evaporator problems |
For my 2019 BMW X5 sdrive40i, the a/c evaporator core failed and began leaking refrigerant, resulting in complete loss of cold air from the a/c system. The vehicle had approximately 50,000 miles. The repair required full dashboard removal and cost approximately $4,500 including a rental vehicle. This appears to be a widespread issue on 2019–2025 BMW X5/x6/x7 models, suspected to be caused by r-1234yf refrigerant incompatibility with the aluminum evaporator core. The leaking r-1234yf refrigerant is also an environmental concern. R-1234yf is a hydrofluorocarbon (hfc) greenhouse gas with a global warming potential significantly higher than co2. An uncontrolled leak of this refrigerant directly into the atmosphere — due to a defective factory-installed evaporator core — contributes to environmental harm and violates the spirit of epa regulations governing refrigerant emissions. Consumers should not bear the financial burden of a known manufacturing defect that also results in the uncontrolled release of a regulated substance. BMW has not issued a recall or extended warranty for this component despite widespread owner reports of the same failure. I am requesting NHTSA investigate this issue and compel BMW to issue a formal recall and provide reimbursement to affected owners.
