What owners say
Vehicle stalled and would not start due to issue with the electric motor.
Tysinger replaced the fuel tank on 08/30/2018. The car has had problems with the fuel tank since I purchased the car. The car has been making a loud bang and then there is a strong smell of smoke afterwards. This has happened at least 45 times since I purchased the car, I thought the problem would go away, but it has not. The car stalls at red lights and during stop and go traffic, there is a strong smell of smoke after it stalls.
I was driving eastbound in the number 1 lane of california highway 24 about 1/4 mile before the tunnel road exit. I heard a noise coming from the engine are of the car, looked at the instrument cluster and noticed that the engine light had illuminated, and experience a sudden loss of power. I pulled off of the highway at the tunnel road exit and stalled on the off ramp. I attempted to restart the engine twice by turning the key. I saw smoke in my rearview mirror, exited the vehicle, and saw flames coming from underneath the vehicle. I called 911 and gave the dispatch operator my location. By the time the highway patrol and local fire department arrived, my car was totaled. The attached photos tell the story of the damage.
I was driving down the city highway - route 283 to get something to eat as I turned my car stalled out completely. Trying to turn over it would try to start but never start. Car has just over 17k miles on it. Thankfully I wasn't in heavy traffic as this could have caused an accident by someone rear-ending me because of the reduced speed and stall. I had to have someone push me up to a parking lot while I waited for a tow truck. A month later I am still waiting on a replacement fuel pump. The original bosch keeps blowing fuses and stalling out. My mechanic test drove it and he had to be towed back to his shop as well because of a stall/blown fuse because of the fuel pump issue. These fuel pumps seem to be on back order because lots of smart cars are having the same issue at the moment with their bosch fuel pumps.

While driving at night at about 45 miles per hour, I was shifting into fifth gear and the car just went blank. The lights went out and all noise ceased to exist. At first it was a bit of a shock, so I immediately pulled off of the road onto the dirt. Luckily there were no cars around as the sudden lose of power could have caused someone to run into me, as I had no lights. After looking around the insde of the car I noticed that the key was in the off position. The key on this car is in the middle console, right next to the gear shift selector. I determined that upon shifting my jacket sleeve had brushed against the key, and becuase the key is so easy to turn off from the on position, the key just turned off while driving. This was the first occurrance of this, as it happend one more time. I have had to remember not to leave my hand down by the shift lever, in fear of turning off the key without knowing it.
