Hi guys,
First post here. I have a 2008 IS250. Long story short about June of 2014 my car was burning oil. The dealership put a new short block in it because it had a scored cylinder(it was under extended warranty). After the new short block in June 2014 the car progressively got worse with sputtering while cruising . When I would come to a stop after the sputtering I would have no acceleration. My tranny would shift through the gears, the RPMs would rise in accordance with tranny, but the car would only go about 20 mph. This would happen regardless if I stabbed the gas to to floor, babied it, or accelerated normally. After a few seconds it would clear out and go normally until I would cruise again. Took it back to the dealership, where my throttle body was replaced, and that didn't fix the problem. They then replaced my timing chain tensioner, that didn't fix it. They checked for carbon build up, checked the injectors, checked the gas, checked the gas tank, checked the fuel pump, checked the fuel psi, all of which was normal. They even tried a new computer which didn't fix the problem. There has never been a check engine light and there has never been any codes when put on the computer. Finally in July of 2015 (after in and out of numerous dealerships) they found out that there was a handful (8) of defective short blocks in the entire USA that caused an inaudible knock causing the engine to !Removed!. Another new short block was put in and I picked up my car in August 2015. Now I'm here looking for answers or similar experiences because I have the exact same problem again with the sputtering, no acceleration, no check engine light and no codes. All the dealerships within 150 miles of me are stumped, and my local dealerships are giving me the run around. Headquarters has already had 2 open cases with me for this issue and cannot do anything to help until the car is inspected for a 3rd time.
Does anyone have any ideas of what this could possibly be?!?! Could I have that good of luck to get 2 out of 8 defective short blocks in the entire United States??
Any input is greatly appreciated.
