The contact owns a 2014 Chevrolet Silverado 3500. While driving 65 mph, the speedometer decelerated to 1 mph without warning.

Gas mileage complaint. Stated mileage (hwy ) is 22 mpg, the first six monthes of driving did achieve this stated mileage, occasionally as much as 23 mpg.after 2 recall service visits and an oil change, the mileage abruptly dropped to 18 mpg I complained to chev. Service in cottage grove, or several times over the course of 4 monthes they advised me to change fuel (service stations, ) put a fuel booster additive in the tank, check tire pressure.they also stated that the fuel mnfrs. Changing the fuel blend for the winter season may be the cause. No service codes in the computer. None of the suggested "fixes" have changed the mileage, still at around 18 mpg. Something caused this sudden drop in mpg.I have a couple of ideas, 1. one recall was a computer software upgrade, wrong shift parameters installed ? 2. at prescribed oil changes,06/03/14 &12/18/14, ( truck requires dexos 0-20 oil ) maybe wrong oil was installed " one invoice shows 5W-30 was installed. However dealership denies installing wrong oil. How can I have the oil analyzed to determine which is in the truck "

Silverado 3500 6-cyl

  • 5,010 miles
Shortly after starting truck and departing to local store I noticed a strong fuel odor. After driving approximately 3-4 miles my gas tank went from 3/4 full to nearly empty, around the same time passerby's started flagging me down stating that my truck was leaking fuel and smoking from underneath. I immediately pulled over to closest parking lot to realize the truck was massively leaking fuel from different areas and was indeed smoking as if it was about to catch fire. I turned the truck off and moved away. The fuel leak stopped and the smoke eventually dissipated. It was been towed back to dealer by Chevrolet road side and is currently being checked for the problem.
