Suffered total loss of hydraulic pressure three times as different components failed, leaving car with no brakes, suspension or power steering.
Nearside wing mirror broke off.
Offside mirror adjustment control stopped working.
Electric windows died at exactly the same time as the glove-box light. (?)
Anti-lock braking system computer failed making the anti-lock system work every time the brakes were applied.
Sunroof leaked when it rained.
The Xantia was very comfortable, nice to drive, and a good looking car. It felt pleasantly solid and had a nice interior and great ride.
Sadly, good points outweighed by abysmal reliability.
Hmm electric windows failed same time as glovebox light... a real mystery there *rolls eyes*. The anti-lock braking is a permenant feature which means... its permentant and it doesn't switch off??!!
