Cars with the most climate control problems

Ranking of the cars we have analysed by the severity and frequency of their documented climate control faults. Each fault links to its page: symptoms, cost, how to check it and sources.

Of the 522 cars we have analysed, 73 have documented climate control faults. The one with the most accumulated risk is the Porsche Panamera I, because of “short circuit in the air conditioning fan control unit”; it is followed by the Kia Sportage IV and the Citroën Berlingo III. For 449 we have found no documented climate control faults.
