Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The gas tank on the 2003 Lexus LS430 can be easily damaged by careless placement of the jack at the rear mounting point. My car was recently damaged this way at dorschel Lexus (rochester, new york, and I am concerned that there are any number of such cars on the road. Partly crushed gas tanks may not be noticeable to the owner unless one looks under the vehicle. This may predispose these vehicles to fuel leaks and early corrosion around the gas tanks.”
