We are reaching out to the community today to see if anyone else has encountered a similar issue with their Mercedes EQA. One of our readers reported a worrying fault with their 2021 EQA model, specifically concerning the heating and cooling system. They experienced a complete lack of warm air circulating within the vehicle from December of last year onwards. Crucially, no error warnings were displayed on the car’s system, leading to a delayed diagnosis when the vehicle was eventually booked in for a service at the dealership.
While the absence of heating was initially perceived as a minor inconvenience, the situation escalated dramatically and dangerously. In a recent road traffic accident, directly attributed to this heating system malfunction, the driver’s windscreen fogged up due to external weather conditions and the temperature differential inside and outside the car. Reacting to the sudden fogging, the driver instinctively activated the “max demist” function. However, instead of clearing the windscreen, the system blasted cold air, exacerbating the condensation and instantly reducing visibility to zero.
This incident highlights how a seemingly minor fault in the Mercedes EQA’s heating system can quickly transform into a significant safety hazard. The confluence of cold, damp weather conditions and a malfunctioning demist system created a “perfect storm”, turning the vehicle into a potential danger to the driver and other road users.
We are keen to understand if other Mercedes EQA owners have experienced comparable heating and demisting issues. If you have encountered similar problems, we urge you to share your experiences. Were you able to identify the root cause of the fault? And what steps were taken to rectify the problem with your EQA’s heating and cooling system? Your insights could be invaluable in helping others understand and address this potentially dangerous issue in their Mercedes EQA vehicles.
