2021 Mercedes-Benz Sprinter 1500

The 2021 Mercedes-Benz Sprinter 1500 is a versatile van popular for commercial use and camper conversions. It offers a range of configurations and is appreciated for its spacious cargo area, comfortable ride (for a van), and available technology. However, some owners have reported issues with reliability and the cost of maintenance. Available engines include a 2.0L turbocharged 4-cylinder gasoline engine producing 188 horsepower and 258 lb-ft of torque, and a 3.0L turbodiesel V6 producing 188 horsepower and 325 lb-ft of torque. Both engines are paired with a 9-speed automatic transmission (9G-TRONIC). Some common complaints include electrical glitches, emissions system problems (especially with the diesel), and relatively high maintenance costs.

Summary

The 2021 Mercedes-Benz Sprinter 1500, while appreciated for its utility and features, can present owners with a range of issues. The most significant problems tend to revolve around the diesel engine’s emissions systems and electrical glitches. Transmission issues are less frequent but can be costly to address if a valve body replacement is required. The severity of the issues ranges from minor inconveniences (infotainment glitches) to potentially disabling problems (DEF system failures). Repair costs can vary significantly, with diesel engine repairs and transmission work potentially exceeding $1000. Potential buyers should be aware of these common issues and factor in the possibility of higher maintenance costs when considering this vehicle.
