Operating my vehicle, the engine starting running poor. Jaguar dealership explained poorly designed timing chain tensioners and arms have failed because jaguar made the components out of a cheap plastic, that is known to crack and cause the valves to contact the pistons. Jaguar updated the tensioners to metal , but refuses to accept responsibility for this design flaw and want to charge several thousand dollars to upgrade to the better designed parts. They refereed me to service bulletin technical service bulletin no. X303-68 , but it states if you haera a rattling noise, however it also states you may not hear a rattling noise, my car did not, and out of no where , thengine stopped running due to this design flaw, that has been updated. In fact, this effect every single 4.0 engine, that's millions! It's time this becomes a recall to replace these parts free and repair any engine component damaged from their failure.a customer should not have to pay thousands for an defective plastic tensioner, some one put inside a hot running engine, that was a very dumb idea, and the failure may even occur as young as 32,000 miles.
