For most folks, Mercedes-Benz represents the premier of automotive luxury. While their cars excel in many regards, reliability might not be one of them. According to a recent RepairPal survey, Mercedes attained an overall reliability score of 3.0 out of 5.0. This is just about average. Although, it gets worse for them once we take other car brands into account. Out of 32 other automakers that took part in this survey, Mercedes-Benz ranked 27th. This was assessed as an average across 345 unique Mercedes-Benz models. Based on Consumer Reports' studies, the GLE and GLS SUVs have both scored the lowest among other Mercedes models concerning reliability. Meanwhile, the C-Class and E-Class sedans are the most dependable Mercedes models that you can buy today.
