Description of the problem | Check engine, vsc, traction lights comes on as vehicle comes to a stop with a rough idle, and at times exhibits a temporary loss of power intermittently, while the vehicle is mobile/rolling. Lexus sent out a tsib letter to us owners for similar symptoms with possible diagnostic trouble codes(dtc): p0300-p0306. Further, according to lexus corp. "the check engine light may illuminate for reasons of unrelated condition." lexus corporation suspects the cause of problem is carbon deposit accumulation in the intake valves and a replacement of piston ring set and or pistons may be indicated. If this is what's occurring inside the engine and is inherent to is250 models only ,then it would seem to a reasonable person there is a design and potential safety flaw in these vehicle models. Also, because of this design flaw, my vehicle is now having catalytic failure and a what sounds like a rattle during a cold crank start of the vehicle. However, when a vehicle is taken to a dealer, the lexus dealers are quick to dismiss the problem by the claims that the symptoms are not replicable enough for them to verify the problem. The temporary loss of power may one day cause the driver to have a serious accident should the steering wheel lockup or should the problem happen during hill ascends, which may cause the vehicle to roll back into traffic or off the main road. Why is lexus corporation not making this issue a safety recall, and rather, just treating it as a concern nature. I would beseech the traffic safety board to please look into this matter as to avoid any injury or worse, a loss of innocent life. This is my first lexus vehicle and it has become a very disappointing experience. |
