Engine

3.0L V6 Diesel

• Diesel Exhaust Fluid (DEF) System Issues
  • Description/Symptoms: Malfunction of the DEF system, leading to warning lights, reduced engine power (“limp mode”), and potential inability to start the vehicle. Faulty sensors (NOx sensors, DEF level sensor), DEF pump failure, and clogged DEF injectors are common causes.
  • Solution: Diagnosis with a Mercedes-Benz specific scan tool is essential. Replacing faulty sensors, repairing or replacing the DEF pump, or cleaning/replacing DEF injectors are common solutions. Software updates to the engine control unit (ECU) may also be necessary.
  • Estimated Cost to Fix: $200 - $2,000+ depending on the specific component needing repair or replacement.
  • Recalls: None Found
• EGR Valve Issues
  • Description/Symptoms: Clogging or failure of the Exhaust Gas Recirculation (EGR) valve. This can cause rough idling, poor acceleration, black smoke from the exhaust, and potentially trigger the check engine light.
  • Solution: Cleaning or replacing the EGR valve. Diagnosing and addressing the root cause of excessive soot buildup may also be required.
  • Estimated Cost to Fix: $300 - $1,000+
  • Recalls: None Found
• Turbocharger Issues
  • Description/Symptoms: Turbocharger failure, resulting in a loss of power, excessive engine noise, and potential engine damage.
  • Solution: Replacement of the turbocharger. Oil leaks and blockages in the oil lines that lubricate the turbocharger need to be addressed, as well.
  • Estimated Cost to Fix: $2,000 - $4,000+
  • Recalls: None Found

Transmission

7G-Tronic Automatic Transmission

• Slipping or Harsh Shifting
  • Description/Symptoms: Transmission slipping between gears, harsh or delayed shifts, and/or failure to shift properly. This can be caused by low transmission fluid, worn valve body components, or internal damage to the transmission.
  • Solution: Check and top off or replace transmission fluid, repair or replace the valve body, or in severe cases, rebuild or replace the transmission.
  • Estimated Cost to Fix: $200 (fluid change) - $5,000+ (transmission replacement).
  • Recalls: None Found
• Torque Converter Issues
  • Description/Symptoms: Torque converter shudder or vibration, particularly at lower speeds or during light acceleration.
  • Solution: Replacement of the torque converter or a full transmission rebuild in severe cases.
  • Estimated Cost to Fix: $1,000 - $3,000+
  • Recalls: None Found

Suspension

• Rear Leaf Spring Sagging or Failure
  • Description/Symptoms: Rear of the vehicle sagging, particularly when loaded. Excessive noise from the rear suspension, and potential damage to other suspension components.
  • Solution: Replacement of the rear leaf springs, potentially with upgraded or heavy-duty springs to better handle load.
  • Estimated Cost to Fix: $500 - $1,500+ per spring depending on brand and if installed by a shop or yourself.
  • Recalls: None Found

Electrical

• Sensor Failures (ABS, ESP, etc.)
  • Description/Symptoms: Warning lights illuminating on the dashboard related to the anti-lock braking system (ABS), electronic stability program (ESP), or other safety systems. These can be caused by faulty wheel speed sensors, yaw sensors, or other related components.
  • Solution: Diagnosis with a Mercedes-Benz specific scan tool to identify the faulty sensor(s). Replacement of the defective sensor(s).
  • Estimated Cost to Fix: $150 - $500+ per sensor depending on shop/self install.
  • Recalls: None Found
• Battery Drain Issues
  • Description/Symptoms: Rapid battery drain, particularly when the vehicle is parked for extended periods. This can be caused by parasitic draws from aftermarket accessories, faulty electrical components, or a failing battery.
  • Solution: Diagnose and eliminate any parasitic draws. Test and replace the battery if necessary. Ensure the charging system is functioning properly.
  • Estimated Cost to Fix: $100 - $300+ depending on severity of electrical issue.
  • Recalls: None Found

Exterior

• Sliding Door Issues
  • Description/Symptoms: The sliding door can become difficult to open or close, can become misaligned, or the motorized function can fail.
  • Solution: Adjustment of the door, lubrication of the moving parts, repair or replacement of the motor or the door latch.
  • Estimated Cost to Fix: $100 - $1000+
  • Recalls: None Found

Interior

• HVAC Blower Motor Failure
  • Description/Symptoms: HVAC blower motor malfunctions, resulting in weak or no airflow from the vents. The blower motor resistor or the blower motor itself may be at fault.
  • Solution: Replacement of the blower motor resistor or the blower motor.
  • Estimated Cost to Fix: $200 - $600+
  • Recalls: None Found

Summary

The 2019 Mercedes-Benz Sprinter 4500, while generally a reliable vehicle, can experience some common issues. The diesel engine’s DEF system and EGR valve are prone to problems, and the transmission can suffer from slipping or harsh shifting. Suspension and electrical issues can also arise, and the sliding door and HVAC can also have issues. Repair costs can range from a few hundred dollars for sensor replacements to several thousand dollars for major engine or transmission work. Prospective buyers should be aware of these potential issues and factor them into their purchasing decision.
