2020 Volvo VAH 640

The 2020 Volvo VAH 640 is a heavy-duty dump truck, powered exclusively by a Volvo D13 engine, paired with a Volvo I-Shift Dual Clutch transmission, delivering 425 horsepower and 1,650 lb-ft of torque. Drivers value its reliability, robust construction, and superior towing capabilities. However, it has been reported to have some notable issues.

Engine

D13

• Turbocharger Failure: Malfunctioning of the variable geometry turbocharger can lead to reduced performance, poor acceleration, and increased fuel consumption. Requires turbo replacement. $3,000 - $5,000+
• Exhaust Gas Recirculation (EGR) Valve Sticking: Soot buildup can cause the EGR valve to stick, leading to reduced engine power and increased emissions. Valve cleaning or replacement is necessary. $500 - $1,200
• Injector Failure: Defective fuel injectors can cause rough idling, poor fuel efficiency, and engine misfires. Injector replacement is needed. $800 - $1,500+

Transmission

I-Shift Dual Clutch

• Clutch Pack Wear: The clutch packs may experience premature wear, resulting in slipping, shuddering, or difficulty shifting. Clutch pack replacement is required. $2,500 - $4,000+
• Gear Selector Malfunction: Occasional issues with the gear selector may prevent the vehicle from shifting properly. Re-calibration or replacement of the selector may be necessary. $300 - $1,000

Suspension

• Leaf Spring Breakage: Overloading or uneven loading can cause the leaf springs to break, affecting handling and stability. Spring replacement is required. $1,200 - $2,000+
• Shock Absorber Failure: Worn or damaged shock absorbers can compromise ride quality and stability. Replacement of shock absorbers is needed. $600 - $800+

Electrical

• Battery Discharge: Prolonged periods of vehicle inactivity can lead to battery discharge. Jump-starting or battery replacement may be necessary. $100 - $300

Exterior

• Headlight Condensation: Moisture buildup inside the headlights may occur due to inadequate sealing. Headlight replacement or resealing is required. $400 - $1,000+

Interior

• HVAC Malfunction: Malfunctioning HVAC system components can result in inadequate heating or cooling. Component replacement or system recharge is needed. $500 - $1,200+

Summary

Overall, the 2020 Volvo VAH 640 is a reliable and capable dump truck but with potential issues to consider. Engine and transmission problems, particularly turbocharger failure and suspension issues, can be costly to repair. Regular maintenance and attentive driving are crucial to mitigate potential problems.
