Top issues to watch for
The most serious Volvo 800 Series problems ranked by severity. We track 5 known issues — here are the ones you need to know about first.
Dangerous
Flexible brake hose deterioration (850)
The flexible brake hoses on 850 series models deteriorate at an exceptionally high rate compared to the fleet average. MOT data shows this model fails brake hose inspections at 18.4 times the national rate, with failures concentrated in the 80,000-150,000 mile range. The hoses become excessively damaged, chafed, twisted or stretched, creating a direct brake system failure risk. This is the most dangerous documented defect on the 850 series.
What happens if ignoredFailed brake hoses can lead to complete brake system failure and loss of braking ability. If a hose ruptures during driving, brake fluid loss will result in brake pedal going to the floor with minimal stopping power. The car should not be driven if brake hoses show signs of deterioration.

Power steering system failure (850)
The hydraulic power steering system on 850 series models fails at 22 times the fleet average rate according to MOT data. Failures typically involve power steering fluid leaks or complete system malfunction, concentrated in the 80,000-150,000 mile range. The high failure rate suggests a design weakness in either the pump, rack, or hydraulic connections specific to this generation.
What happens if ignoredComplete power steering failure makes the car extremely difficult to steer, especially at low speeds and during parking. While the car remains controllable at highway speeds, maneuvering in tight spaces becomes dangerous due to the physical effort required. Continued driving with a leaking system will damage the pump.

Front suspension bush and joint wear (850)
Front suspension components including bushes, pins, and joints wear at 17.6 times the fleet average on 850 series models. MOT data shows consistent failures across the 80,000-150,000+ mile range. The high failure rate suggests the front suspension design places unusual stress on these components, leading to premature wear of control arm bushes, anti-roll bar links, and ball joints.
What happens if ignoredWorn suspension components affect handling, steering precision, and tire wear patterns. In severe cases, failed ball joints or control arm bushes can cause loss of steering control. The vehicle will fail its MOT test and should have suspension components inspected and replaced as needed.

Emissions system failure - petrol engines (850)
Petrol engines in the 850 series show exceptionally high emissions failure rates on MOT testing. The 2.3-litre engine fails emissions at Failures include excessive emissions levels and inability to complete emissions testing, suggesting catalytic converter deterioration, lambda sensor failure, or fuel system problems specific to the 5-cylinder engine design.
What happens if ignoredFailed emissions mean immediate MOT failure and the car cannot be legally driven on public roads. Repair costs can be significant if the catalytic converter requires replacement. Continued driving with emissions problems may damage other engine components and worsen the underlying issue.
