2008 Lexus LS460 Engine Problems

“After a manufacture recall for the valve spring replacement, I had my first oil change. Directly after the oil change, I noticed that around 35 MPH when I needed to pass a vehicle, I would step on the gas (most of the time pushing the accelerator pedal to the floor) the car was very sluggish and unresponsive. It would take about 10 seconds for the vehicle to slowly accelerate and then the car would take off with the rpms climbing near red line until I released my foot off the accelerator. If I set the cruise control at around 35-40 MPH the cars engine surges. …”

“This has happened over 5 times since owning the vehicle. After oil changes and off/on throughout owning the car it will have a hesitation on the acceleration. It will have high RPM's, but it is not going anywhere (loud engine noise). This is very dangerous if it decides to do this when passing someone on the highway and this morning it did it while pulling out into traffic and almost got hit as the vehicle did not move.”

“After the vehicle has an oil change, the car will (intermittently) hesitate to accelerate. This is especially dangerous when you are trying to merge into the freeway or similar occasions. When attempted to depress the gas pedal with expectation that the car will respond and accelerate as normal, the engine just revs up and the vehicle doesn't move any faster than current speed. This will continue for 5-10 seconds then it kicks in. This delays is very dangerous when you want to get out of harms way (accelerate to merge into freeway, passing etc). …”
