The engine oil level may rise. This situation may lead to the engine speed being maintained or possibly increased after the throttle pedal is released. In an extreme situation the engine may continue to run after it has been switched off.
The auxiliary drive belt tensioner may fail. This can lead to loss of steering power assistance and a slight possibility of loss of drive, should the drive belt or tensioner invade the cambelt area.
A joint on the high pressure line of the power assisted steering may not have been assembled correctly. This may lead to a leakage of steering fluid into the engine bay. This could result in sudden loss of power assistance, but in extreme cases, it could result in a localised fire within the engine bay.
A section of the gear shift mechanism may over time become loose and cause the mechanism to become jammed. If this was to occur, it might not be possible to change gear or select neutral.
It has been identified that a number of fuel pressure pipes may have a defect, which could result in a fuel leakage. Although it can be identified by the smell of fuel, it is possible, although unlikely, that an external heat source could ignite the fuel, so resulting in a fire.
On effected petrol and diesel engines a spring clamp on the radiator hose connecting it to the water inlet pipe may be insecure. If not rectified the engine may lose coolant, overheat, seize and suddenly slow the vehicle rapidly to a halt.
On a small number of S60 cars it is possible that secondary bonnet catch will not lock in the closed position correctly. If the bonnet is not closed correctly, it is possible that the secondary bonnet catch will not secure the bonnet, which could result in it opening unintentionally.
It is possible that the hose connection between the coolant expansion tank and the bleed hose can work loose. If this should occur, then coolant will leak and air will enter the system. Under these conditions the “low coolant level” warning light will not function. If the vehicle is driven in this condition it will cause engine damage and in the extreme, possible failure.
It is possible that an electrical short circuit within a connector could result in the illumination of the “Airbag System Service Required” message and Supplemental Restraint System warning lamp on the dashboard. Should this occur, the driver airbag would not deploy as intended if the vehicle is involved in a collision.
It has been identified that the standard wheel securing bolts may not have undergone the correct hardening process. This will result in corrosion, a noise and/or vibration. If this condition is not rectified, there is a possibility that the wheel may become loose and detach.
Under certain side impact scenarios, the side panel on the driver seat may contact the quick fix seatbelt release button and the belt may detach.
A power steering hose may come into contact with the engine cooling fan. As a consequence, the hose may become damaged and subsequently leak, resulting in loss of power steering assistance.
It has been identified that, the fuel rail beneath the vehicle that protects the fuel line may not be properly attached, thereby exposing the fuel lines to possible damage.
It has been identified that due to internal leakage the gearbox hydraulic control module may not be able to engage or shift gears as intended.
It has been identified that a joint between the power steering high pressure lines and the steering gear may not have been assembled correctly. This may result in a power steering hydraulic fluid leak, and a sudden loss of steering assistance. Due to the pressure within the hydraulic system, hydraulic fluid may be sprayed onto the engine with the attendant risk of fire.
The Auxiliary Belt Tensioner may fail resulting in loss of Power Assisted Steeering and loss of Drive
Fuel may leak from a defective fuel pressure line. Although unlikely, there is a potential that an external ignition source could ignite the fuel and result in a fire in the driver side wheel arch area.
On certain five cylinder engines, it is possible that the high pressure fuel pipes may not have been correctly installed and may leak. This should be identified by a smell of fuel from the engine bay. However, it is possible that in extreme cases an engine bay fire could occur.
When driving at low speeds a fault within the software calibration of the engine and transmission control modules may lead to a drop in the engine idle speed when braking or releasing the accelerator. In extreme cases, this may result in the engine cutting out without warning.
The inflatable curtain may have been fitted incorrectly which could prevent it from deploying as intended.
Garmin have identified that certain model Nuvi portable navigation products fitted with a specific battery and printed circuit board design can, under rare circumstances overheat. This could result in a unit fire.
It is possible that the engine oil level may rise above its maximum level due to overfilling and/or dilution by fuel. This may result in the engine speed being maintained or possibly increased after the throttle pedal has been released. In extreme cases, it is possible that the engine may continue to run after it has been switched off.
Volvo quality follow-up procedures have identified an issue on a number of model year 2007 C30, S40 and V50s relating to the engine cooling fan control module. Under certain operating conditions water intrusion could occur into the control module causing a short circuit which, in very rare instances, could result in a fire in the engine compartment.
It is possible, in certain circumstances, for the engine oil level to rise above the maximum level. This situation could lead to engine speed being maintained or possibly increased after the throttle pedal is released. In extreme cases the engine could continue to run after it has been switched off.
It is possible that the driver and passenger front powered seats may not be fitted with the front stop lug. The lug restricts the movement of the seats and if not fitted, it is possible to position the seats too far forward or backwards. This could increase the chances of injury should the vehicle be involved in an accident.
It has been identified that the wiring harness for the Side Impact Protection System airbag (SIPS) on the drivers and passengers front seats may have been routed incorrectly. This could result in the wiring harness becoming damaged which will illuminate the Supplemental Restraint System (SRS) light on the instrument panel. If the SRS light is illuminated then additional care should be taken when driving the vehicle as SRS functions may be affected.
Vehicles with manual gearboxes and start/stop functionality have Parking Brake Module (PBM) software that may allow the parking brake to unintentionally release. The unintended release of the parking brake can only occur when the engine is running and the gearstick moved, so it will happen when the vehicle is attended.
The crankshaft may not have been sufficiently hardened and may fail, this in turn can lead to sudden and catastrophic engine failure. The failure may be preceded by loss of power and a knocking noise.
Affected vehicles have interior panels that may prevent the inflatable curtain airbags from deploying as intended. This could reduce the level of protection offered to third row passengers in the event of an accident.
A hose for the power steering assistance hydraulics could come into contact with the cooling fan. This would cause a noise, which an observant driver may be able to hear. If the hose and fan conflict for long enough then it is possible for the hose to leak power steering fluid to the degree that servo assistance could be lost.
