My car stalled in the middle of an intersection. It had to be towed to the Lexus dealer, where it was determined to be a fuel pump malfunction. My car was not subject to the fuel pump recall but it should have been.

When I press on my brakes they make a loud roaring sound right away. Usually when brakes are about to go out its usually a squeaky noise then it will go to loud roaring noise. There has not been an indicator on the dash about any issues with the vehicle. I found it rather odd that the brakes made the roaring noise immediately. It didn't squeak at all. I would like for this matter to be looked into. There is no way there should be a brake system failure right away. The schrader valve has a crack and freon is leaking out of and the air is not blowing cold air.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2014 Lexus RX 350 verdict →
