I first heard knocking noise upon cold start-up. This has now become a chronic noise. When getting truck serviced for another matter the mechanic informed me that the vvt-I bolts were defective and needed to be replaced for a charge of $3500-$5600. He also noted this was expensive because it is a Lexus engine. Upon researching this more I discovered this is the same engine 2gr-fe v6 installed in the Lexus rx350s with same problem. However, this has been a major recall by Toyota for Lexus vehicles but not Toyotas. I contacted Toyota but they refuse to address this issue even though this is exact same defect which is a recall for Lexus models. See article //parts. Olatheoyota. Com/gr-series-engine. Html. The recall is listed on NHTSA. Once bolts loosen the vvt-I gear housing and sprocket to separate and result in the engine stopping while the vehicle is being driven, increasing the risk of a crash. See article: Toyota recalls various Lexus vehicles with engine bolt problems the bolts could become loose due to abnormal impacts 09/10/2013 | consumeraffairs by james limbach I cannot understand how these defective bolts under a Toyota body style, but on the same engine are excluded from this major recall. The serious consequences remain the same regardless of body style should bolts loosen during high speeds. I have escalated this complaint to the highest level at Toyota with no results so I am compelled to file an official complaint with your department. We have a toddler on board each day driving this vehicle without funds to repair this problem and are now unable to sell the car. Your attention to this matter is appreciated.
