What owners wrote

While driving in town around other vehicles namely those with bright lights and at stop lights. It felt as though there was a ton of pressure inside my vehicle almost like the the windows were going to explode. Im not sure how to explain it maybe a gravataional downward pull? Almost like a chemical burn from the brightness of other headilghts and the vehicle mirrors mixed chemical nomenclature were having a bad reaction. This caused me to become aware of an issue.

Hi! I noticed very strong gas fumes after filling my car with gas. I took the car to the dealer on friday, september 22, 2017 and had the fuel pump replaced, after filling my car with a tank of gas, I noticed strong fumes in the car. I noticed the fuel needle went from 401 miles to 388. I drove home parked my car in the garage moments later my daughter arrived home and began complaining about the strong gas fumes in the garage and gas leaking underneath my car.
