Its DEFINITELY wear and tear, disappointing though some might see it. If the chain has been inspected at service intervals, then thats all anyone could be expected to do.Much of this is down to sheer luck one way or the other, but its ridiculous post warranty to think that anyone might have a claim, unless of course they have been clearly lied to .
Yes. A fault in the timing chain usually leads to a total loss of the engine as the timing chain synchronises the mechanical operation of the engine. If this goes wrong bits of the inside of the engine will be physically destroyed (the engine will have to be rebuilt). It is MOST IMPORTANT to replace the timing chain on an engine WHEN the manufacturer says it need to be done.
The timing chain itself is not hard to change , but the engine has to be removed to do it, that is why it is such a costly job if taken in to a garage . a common fault i believe on these engines .
It Is Believed It Was A Mechanical Fault With The Car, Not Ayrton's Fault
It must have a mechanical fault.
It's hard to prove fault in these cases but the timing belt change requires removing the crankshaft pulley. So the mechanic would have had to have at least seen its condition. More likely, he damaged the pulley in the process of replacing the timing belt. Maybe he used an impact wrench when he reinstalled it and the key wasn't aligned correctly?

not if you re pack the bearings!
A mechanical fault or a drunk driver.
The six point technique of fault finding used in mechanical maintenance is called the hexagonal method. It also sometimes called the six sigma and is a process of quality control.
Normaly you don't change the timing chain on bmw 520d model 2008 it supposed to last for life but the 520d model 2008 it's prone to a timing chain failure ( Design fault from Bmw ) which bmw want recognise that ! But there is a lot of people was affected ! 4% of those cars are affected . If you heard any strange noise like rattle or ticking noise coming from the back of the engine , go and check it at a Bmw Dealer , make sure to have a warranty because if it fail it cost to repaire it almost 4000£ and if it snaped you will need probably a new engine or second hand one ! Most of N47 engine from 2007 to 2011 are affected ! more info google N47 timing chain failure.
The Suzuki Grand Vitaras 1999-2002 have a major design fault, more specially the J20 class engine. The timing belt tensioners will fail eventually.. usually out of your waranty period. The oil lubrication holes on these tensioners are not big enough and will block, even if you change the oil every 3000 miles. The tensioner will develop a rattle, and eventually fail. The Suzuki engine is a interference engine, meaning the valves on the engine 'interfere' or move where the pistons in the engine move. If the timing chain fails, the piston will hit the valves, causing major engine damage. Suzuki say you should never have to replace the timing chain system. This is wrong. Having talked to Suzuki, they have had these tensioners fail anywhere from 60000 km to 130,000 km. You will be up for a $2500 NZD job to replace the chain system and fix a problem that is a Suzuki design fault. Suzuki knows about this problem as there is a service bulletin on this problem. However there is no recall or support outside the warranty period.
Yes. That's what made that island chain.
