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.

Vehicle stalls randomly bringing about a failure of all systems sometimes in the middle of crowded and fast freeways. Doing research on the problem it seems to be common for this type of vehicle and there seems to be a solution with the throttle body assembly design but aparently the manufacturer has not issued a recall for it and many people go to the dealerships spending thousands of dollars in repairs that do not solve the actual problem. The failure ocurrs randomly while driving under normal conditions.

I have a 1998 jaguar xj8. The vehicle stalls at high speeds, generally after I accelerate over 50 MPH. The vehicle is extremely difficult to control and can only be restarted if you bring it to a stop. I had this happen while driving the car in ca. I was almost killed when the vehicle stalled. Jaguar dealer, santa monica,repaired as cyl burn out. Mechanic told me stalling happened frequently with this model. A few years later,san antonio tx on the 183 highway rush hour. Car stalled causing me to swerve next to center median ripping off the engine cover on debris. Jaguar fixed throttle body not engine cover.service bulletin, defective throttle body. Car ran poorly thereafter. Stalled again year later. Dealer would not repair. $3,000 to fix.. Recently discovered consumers world wide have same problem. Service bulletin repair only short term fix. Jaguar blog in the uk -consumer discovered from a jaguar mechanic , most throttle bodies needed to be cleaned periodically as the lining bad and build up or deposits would form on the walls of the throttle body and cause it to malfunction. My mechanic had heard of similar problems. I called several jaguar dealerships. I was told, off the record, that I could clean the throttle and get by, but certain cleaners would cause the lining to deteriorate. I was told the replacement was a rip off, off the record. Using the appropriate cleaner, the assembly was cleaned without removal. When we turned on the vehicle smoke billowed out of the exhaust for several minutes and then subsided. The vehicle now runs perfectly. Jaguar is profiting from replacement of parts that could be cleaned and need top be cleaned regularly. Replacements effective short term only. Your form allows only "s" type equip". This is a xj8.
