2004 Volvo XC90
Overview
The 2004 Volvo XC90, a pioneering luxury mid-size SUV, offered a blend of safety, comfort, and practicality. It was known for its distinctive Scandinavian design and robust safety features, including Volvo’s signature City Safety system. Available with potent inline-five and V8 engines, and a capable all-wheel-drive system, the XC90 aimed to compete with established European and American rivals. While generally well-regarded for its build quality and family-friendly interior, like any vehicle of its age, certain components can experience wear and require attention. This analysis focuses on documented common issues beyond routine maintenance.

Transmission
AW55-50SN (5-Speed Automatic)
Solenoid Failure
- Symptoms: Harsh shifting, delayed engagement, transmission fault light, slipping gears.
- Solution: Replace faulty shift solenoids. A transmission fluid flush may also be recommended.
- Cost: $500 - $1,000
Torque Converter Issues
- Symptoms: Shuddering at low speeds, slipping, difficulty engaging gears.
- Solution: Rebuild or replace the torque converter.
- Cost: $800 - $1,500
Suspension
Standard Chassis
Sway Bar Links and Bushings
- Symptoms: Clunking or rattling noises over bumps, especially at lower speeds. Reduced handling stability.
- Solution: Replace worn sway bar links and bushings.
- Cost: $200 - $400
Strut Mount Bearing Failure
- Symptoms: Popping or creaking noises when turning the steering wheel, especially at low speeds.
- Solution: Replace strut mount bearings.
- Cost: $300 - $600
Electrical
General Electrical System
CEM Module Issues
- Symptoms: Intermittent electrical problems, warning lights, non-functional accessories (e.g., power windows, lights).
- Solution: Diagnosis and potential reprogramming or replacement of the Central Electronic Module (CEM).
- Cost: $500 - $1,200
ABS Module Failure
- Symptoms: ABS warning light illuminated, loss of ABS functionality.
- Solution: Repair or replace the ABS control module.
- Cost: $600 - $1,100

- Solution: Seal headlight assemblies or replace if severely damaged.
- Cost: $150 - $400
Interior
Cabin Components
HVAC Blower Motor Resistor Failure
- Symptoms: Fan only works on the highest speed setting, or not at all.
- Solution: Replace the blower motor resistor.
- Cost: $100 - $200
Seat Heater Malfunction
- Symptoms: Driver or passenger seat heaters not working.
- Solution: Replace faulty heating elements or wiring.
- Cost: $300 - $600
Summary Verdict
The 2004 Volvo XC90 is a capable and safe SUV, but owners should be aware of potential issues, particularly with the engine and transmission, especially the automatic gearbox. The 2.5L turbo-5 is generally more reliable than the V8, which can suffer from more costly timing chain issues. Electrical gremlins, often related to the CEM module, are also a common concern. Suspension components like sway bar links and strut mounts are typical wear items for a vehicle of this age. While not immune to problems, addressing these known issues proactively can help maintain the XC90’s comfort and utility.
