4
Excellent

RepairPal gave the Mercedes-Benz E400 an overall reliability rating of 4 out of 5 stars, which RepairPal describes as Excellent. This rating ranks Mercedes-Benz E400 10th out of 54 among Luxury Fullsize Cars.

Cost

According to RepairPal, cost is the average total annual cost for unscheduled repairs and maintenance across all model years of a vehicle. Higher average cost alone does not necessarily mean a vehicle is less reliable.

The related cost of a specific vehicle may vary depending on its maintenance and driving history, model year, trim, and features. RepairPal ratings are provided by RepairPal and CarMax is not responsible for the accuracy. These ratings are based on RepairPal Reliability data for select 2006-2020 vehicles as of 09/21/2022. Learn more about RepairPal reliability ratings

RepairPal reports that the average total annual cost for repairs and maintenance on a Mercedes-Benz E400 is $752, compared to an average of $764 for Luxury Fullsize Cars and $619 for all the vehicles RepairPal considered in its dataset.

Frequency

According to RepairPal, frequency is the average number of times the vehicle is brought into the shop for unscheduled repairs and maintenance in a single year. RepairPal reports that it calculates this metric by tracking millions of unique vehicles over multiple years to determine an average number of visits per year for each make and model; and that controls are included to omit small routine visits to shops (such as for oil changes).

The frequency of such visits for a specific vehicle may vary depending on its maintenance and driving history, model year, trim, and features. RepairPal ratings are provided by RepairPal and CarMax is not responsible for the accuracy. These ratings are based on RepairPal Reliability data for select 2006-2020 vehicles as of 09/21/2022. Learn more about RepairPal reliability ratings

According to RepairPal, Mercedes-Benz E400 owners bring their vehicles into a repair shop for unscheduled repairs an average of 0.9 times per year, compared to an average of 2.1 times for Luxury Fullsize Cars and 1.4 times for all the vehicles RepairPal considered in its dataset.

Severity

According to RepairPal, severity measures the probability that a repair will be a major issue. RepairPal reports that an issue is considered severe if a repair costs three-times the average annual repair cost for all models. This threshold will be higher for vehicles that have higher labor rates and parts costs (such as a premium brand).

The severity of repairs for a specific vehicle may vary depending on its maintenance and driving history, model year, trim, and features.

These ratings are based on RepairPal Reliability data for select 2006-2020 vehicles as of 09/21/2022. Learn more about RepairPal reliability ratings

RepairPal reported that the probability of a repair being a severe or major issue is 4% for the Mercedes-Benz E400, compared to an average of 15% for Luxury Fullsize Cars and 12% for all the vehicles RepairPal considered in its dataset.
