Problem overview

Some Mercedes-Benz CLA250 owners report experiencing issues with tire replacement, including constant leakage and potential bursting. These problems can arise from undetected slow leaks, often indicated by a persistent TPMS dashboard light despite proper tire inflation. Additionally, valve stem leaks can significantly compromise vehicle handling and increase the risk of blowouts. Owners also note that older tires are more susceptible to slow leaks due to wear and tear, making regular inspections and timely repairs essential for safety. Furthermore, some owners report a mildew smell emanating from the vents, which may be due to a dirty cabin air filter or mold buildup in the HVAC system. Addressing these issues promptly is crucial for maintaining a safe and comfortable driving experience.
