The check engine light and several other lights came on in my vehicle. Once this happens the vehicle goes into safe mode and prohibits you from driving at normal speeds. I went off the road as I entered the freeway to avoid a semi because I could not accelarate. I discovered this same issue has been found on Toyota models however Lexus has not sent out notices and will not cover. There is a redesign for this air injection pump due to the information below. Toyota has received reports of customer concerns regarding the illumination of the check engine light (malfunction indicator light) due to moisture/water in the air injection pumps and/or air switching valves in the engines of a number of these vehicles. To assist dealer in the diagnosis and repair of these vehicles a tsb has been released. Some of the vehicles covered by this tsb may be outside of the Toyota new vehicle limited powertrain warranty due to age and/or mileage. To assure customers that we stand behind our product, we are offering a warranty extension on the air injection pumps and air switching valves on 2007 to 2010 Tundra and 2008 to 2010 sequoia vehicles.
