“Preparing to stop while entering access gate slowing to around 10 - 15 MPH, after applying brake car accelerated forcing me to reapply brake again and shifting to park.

NHTSA complaint #10692948, filed 2015-03, 201,000 miles“I am an owner of a 1999 Lexus GS300. I just recently had 2 fuel injectors fail and leak gasoline in and over the engine. I was notified that this could have been a fatal fire or explosion. I was not covered underneat warranty for this issue as I took the car in at 70,000 miles. What I have such a problem with is that this car in particular, being that it is a Lexus, should not have too many problems nor repeating problems. This takes me to the history of the vehicle. At 23,000 miles the fuel injectors were replaced. …”
