I was able to get it to the right side in very heavy traffic. I had to be towed. It took a 5 day repair and replacement of the fuel pump power control module. Warranty.
Fuel mileage is way lower then it should be I get 13. 1 mpg and already had to replace one fuel injector.
Vehicle fuel fill back flows everything and vehicle's not full splashing gasoline on the vehicle and the ground which could cause an explosion also. The tank will not be full with fuel range on the dash ranging from 440 to 519. 519 is the full range. The vehicle has been back to dealership service department several times (4) with no resolution. The information screen on the dash has gone blank several times requiring it to go back to the dealership. There had been several message on the screen unrelated to the items listed. The accident avoidance system has locked the front brakes up at both 35 mph and 65 mph several times without a vehicle directly in front and without warning. The unexpected braking causes an abrupt stop and unexpected by the driver behind my vehicle potentially causing a rear end collision.
