Toyota is voluntarily recalling about 245,000 Lexus cars sold in the U.S. because of a possible problem with the fuel pressure sensor installation. The models affected by the recall are 2006-07 GS 300 and GS 350, 2006-09 IS 250, and 2006-08 IS 350.
Insufficient tightening of the fuel pressure sensor, which is connected to some engine fuel delivery pipes that have nickel-phosphorus plating, may cause the pressure sensor to loosen. If this happens, fuel could leak past a gasket that’s used in the connection between the sensor and the fuel delivery pipe. It could also leak through the threaded part of the sensor.
Toyota says there are no warnings that this may occur. However, if fuel is leaking from the fuel pressure sensor, owners may notice a fuel odor coming from the engine compartment. If they do so, Toyota recommends they take it to their dealer for servicing immediately.
There have been four complaints, Toyota says, but there have been no reports of accidents due to the defect. Many of the vehicles in question were previously recalled in January 2009 for fuel lines that experienced corroding over time. Three of the four reports of the current defect were of vehicles not involved in that recall, but one was, leading to the wider range of vehicles involved in the recall.
Toyota is determining how long it will take to produce enough replacement parts before determining a launch date for the recall, which will involve mailings to customers. Recall notices usually include such a date, but Toyota has sped up the reporting process because of its recent history of recall issues.
Once the recall begins, Lexus dealers will inspect cars for fuel leakage. If no leakage is found, they will tighten the fuel pressure sensor. However, if a leak is found, the gasket between the sensor and fuel delivery pipe will be replaced, and the sensor will be tightened. There will be no charge for the inspection and, if necessary, gasket replacement.
The automaker will notify owners of the recall once the necessary parts have been obtained. For more info, owners can call Lexus at 800-255-3987 or go to www.lexus.com/recall/.
Toyota also issued a separate recall for 1.3 million cars worldwide today over a separate problem with a fuel delivery pipe. This larger recall doesn’t affect any U.S. cars.
