The camshaft timing gear was replaced by jim fault Lexus was driving vehicle home and all the dash lit up and engine had no oil. Car hasn't run the same since then without oil needing to be replace 3.5 liters of oil every 300-500 miles so I'm really afraid to go anywhere in my vehicle. Need help! the consumer stated she started having problems with the engine after retrieving the vehicle from the dealer. There was a noise coming from the engine when it was cold and the check engine light illuminated several times, as well as the low oil light. The dealer informed the consumer, the piston rings were worn, but there were no oil leaks. Updated 12/03/14

My vehicle, and doing research there are numerous other Lexus models and years all experiencing oil loss from the timing chain cover gasket causing oil loss that could pose a potential risk to the engine from oil loss and affect drivability and safety. Lexus has not provided a recall on this known issue. They request $3500 to fix the leak with a new gasket. This has the potential to eventually lock up the engine if enough oil leaks out and could cause an accident.

S10 appropriate handling - copy of letter sent to Lexus corporation from re to problems with her 2006 Lexus IS350. The consumer stated the vehicle was making grinding sounds upon start-up. Three days later, the consumer was informed the grinding sound was due to problems with the camshaft gear assembly. After leaving the dealership, the consumer smelled a faint burnt odor, but assumed the air filter might need to be replaced. After a while, the smell became worse and the consumer noticed smoke emitting from the exhaust and from underneath the hood. The check engine light illuminated stating the engine oil was low. The smoke instantly increased. The consumer immediately exited the freeway. The vehicle began making a grinding sounds as she pulled into a parking structure. The next day, a tow truck was sent to retrieve the vehicle. Five days later, the consumer was informed that when the gasket was replaced during the replacement of the engine valve springs that were recalled, a part was left loose and caused the engine oil to leak. The consumer was assured that several flushes were done to make sure the vehicle was at a 100%. on November 25, 2010 while driving, the consumer heard the grinding sound again, then she noticed the temperature gauge jump from high to low in a matter of seconds, followed by the battery signal, indicating a low battery, but then quickly disappeared. As the consumer continued to drive, a rattling noise was coming from under the hood and the check engine light illuminated and the vehicle released smoke. The vehicle was towed to the dealer. Four days later, the consumer was informed that the cap on the radiator fluid had broken off. The vehicle was taken to another dealership where they determined the engine was operating properly, but they discovered oil residue left on the engine that was causing the foul odor. They were unable to determine why the vehicle overheated.
