• Oil leaks: The transmission may develop oil leaks, causing fluid loss and potential damage. Symptoms include oil spots under the vehicle and low fluid levels. The solution is to replace the transmission seals or gaskets. Estimated cost to fix: $500 - $1,500+
• Gear noise: The transmission may make excessive gear noise while driving. The solution is to replace the gears or bearings. Estimated cost to fix: $2,000 - $4,000+

Suspension issues

• Leaf spring failure: The leaf springs can fail, causing the vehicle to sag and ride rough. Symptoms include decreased stability and handling. The solution is to replace the leaf springs. Estimated cost to fix: $500 - $1,000+
• Air bag leaks: The air bags in the suspension system can develop leaks, causing the vehicle to lose height and ride rough. Symptoms include decreased ride height and a hissing noise. The solution is to replace the air bags. Estimated cost to fix: $500 - $1,000+

Electrical issues

• Battery drain: The battery can drain prematurely, leaving the vehicle unable to start. Symptoms include difficulty starting and dimmed headlights. The solution is to replace the battery or diagnose and fix any electrical leaks. Estimated cost to fix: $100 - $500+
• Alternator failure: The alternator can fail, preventing the battery from charging. Symptoms include flickering headlights and difficulty starting the vehicle. The solution is to replace the alternator. Estimated cost to fix: $500 - $1,000+

Exterior issues

• Headlight failure: The headlights can fail, reducing visibility at night. Symptoms include dim or flickering headlights. The solution is to replace the bulbs or the headlight assembly. Estimated cost to fix: $100 - $500+
• Mirror failure: The mirrors can fail to adjust or vibrate excessively. Symptoms include poor visibility and reduced safety. The solution is to replace the mirrors or adjust the mounting brackets. Estimated cost to fix: $200 - $500+

Interior issues

• Heater/AC failure: The heater or air conditioning system may fail to provide heat or cooling. Symptoms include extreme cabin temperatures and discomfort. The solution is to diagnose and repair or replace the faulty components. Estimated cost to fix: $500 - $2,000+
• Seat control failure: The seat controls may fail to adjust the seat position. Symptoms include discomfort and difficulty finding a comfortable driving position. The solution is to replace the seat controls or adjust the seat manually. Estimated cost to fix: $200 - $500+

Summary

The 2011 Volvo VNL is a reliable and fuel-efficient heavy-duty truck, but it has been subject to several reported issues. Engine and transmission problems are the most frequent, with cylinder head gasket failure and shifting problems being the most common. Suspension and electrical issues are also relatively common, while exterior and interior issues are less frequent. The severity of these issues varies, but many can be costly to repair.
