I purchased a 2008 Smart car on 21 oct 13. The check engine light came on at the end of December of 13. I took it in to honest 1 to have it serviced, oil changed, all fluids checked, breaks and engine. I was told that all fluids were great and I paid the bill. The engine light was still on and I went back in. The gentleman worked on it for several minutes and then turned it off. On 30 Mar 14 I was driving home from church and the car died in the middle of the road with all the dash board lights coming on, by the grace of god I was able to get over to the right side of the road with out incident. At the Smart car dealership I am now told that the engine had no water in the radiator, the head is cracked and the engine seized up. Here is the problem. . . . . There was no check engine light and no high temp radiator light show up to say there was a problem. If one had come on you can be sure that I would have had it looked into. I now have to buy a used engine and my concern is that this could happen again.
