Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“When I accelerate from a stop or while moving on a roadway, the engine seems to stall. I'm not talking about the normal turbo spooling stall. It lasts for about 3 to 5 full seconds. When you need power to prevent an accident, you can't afford that time lag, as it could cause your death. The dealer told me that Lexus says it's normal, they all do it. I don't feel any manufacturer would deliberately build and sell a vehicle that would put the occupants in danger of possible death. …”
