While driving, the vehicle's RPM's accelerated quickly and then the vehicle stopped in the middle of the road and would not move. I could not even get it to the side of the road to be out of traffic. All regular maintenance has been performed. The mileage is almost 100,000, but not there yet. This could have been a very dangerous situation as I was heading to an interstate highway. No warning lamps ever lit up and no strange sounds or vibrations ever came from the vehicle. This happened suddenly. No warning whatsoever. The vehicle is being rep…

It was taken to the Chevrolet dealership across from the gas station (total luck). It was diagnosed after 1 day in the shop that all 8 fuel injectors and the two fuel rails were corroded and had snapped upon inspection.( photos were sent to me). Vehicle could not be driven. If stall would have occurred while driving on the interstate at speed of 70 -75 mph, the potential for a major car ac…

Check engine light illuminated then went off and came back on after another drive cycle. Vehicle began to idle rough and experienced hard shifting and acceleration hesitation. I checked the oil and noticed a fuel odor smell on the dip stick and the oil appeared thin. Upon mechanic inspection they found a malfunctioning high pressure fuel pump. This part was recalled on other vehicles of the same model year due to bad welds. This could have resulted in fire if left unchecked.
