Strong gasoline odor inside the car. Dealer removed the rear seat. Removed left and right fuel tank access covers. Found suction jet pump area wet with gasoline. Found the fuel sending unit left side cracked and leaking. They recommended replacing suction jet pump and auxiliary pump costing $1,571. 00. The smell is constant whether moving or not and regardless of location. I cough when driving the car hence I seldom use it. If I can not avoid using the car I open all windows and tell any passenger to avoid smoking to prevent fire. I started to notice this issue mid August 2020.

Car cannot be driven when gas gage shows a little bit less than tank. The range on the car showed almost 90 miles to empty on highway driving and all of the sudden the engine started to lose power and engine light came on, pulled to the side of road limping along at 20 miles per hour with gas pedal all the way to the floor and then engine shut down by itself after 2 miles. After engine shut down all lights on the dash board lit up and needed to turn off car. Restarted the car and the car would not drive in reverse, manual paddle shifter would not work at all, and driving a few yards was impossible. Car shut down a few times and then low gas light came on (two miles before that the range on the dash board was showing almost 90 miles to drive until empty) after this happened, I got towed and put some premium gas. Started the car (after about one hour of the first incident), the engine light was still on and started driving at slow speed to make it home. After a few hours/overnight started the car normal in the morning (no sign of losing power) and engine light turn off. Need to mention that car had fuel tank and other emission components replaced under warranty three months ago for a similar but not identical issue. Problem appeared to happen when tank is either almost full or almost empty and driving long distance on the highway.
