“Took car to Infiniti of santa monica, ca for routine 30,000 mile service. They returned car to me with a ticking/ knocking noise coming from engine. They told me it was from the fuel injector cleaner they added to my car. Took car back to them 3 times in one day and finally refused to leave until they repaired it. They say I need a new engine due to a manufacture defect. I never heard the knock in 30,000 miles, I never heard the knock until I drove out of Infiniti of santa monica, ca. Car only has 30,000 miles on it.”

“I was driving my 2006 Infiniti m35x home sunday night and it began to stall on me while driving. The car wouldn't accelerate and the brakes locked on me. I was on the freeway going about 70mph when this happened. The steering wheel wouldn't turn anymore and I began to panic as another speedy vehicle would potentially rear end me and maybe even kill me. I put my emergency lights on and called for help. My fuel gauge read about a half tank full of gasoline. I had a friend bring me gas to see if that was why this car wouldn't start anymore and unfortunately it was the problem. …”
