While driving my vehicle, I had reached about 40 miles per hour and the car just died. I hadn't done anything, the car simply died. When I first attempted to turn the car back on, it wouldn't crank. The lights, air everything electrical came on, but the car didn't crank. After waiting a few minutes, I tried again and luckily the car started. But this scared me and should not have happened.

Vehicle in my garage, found vehicle battery box and passenger seat flooded due to the air conditioning condensation tube joint located in the battery box disconnected. Vehicle would not start, vehicle will not start, even after emptying the water from the battery box and recharging the battery. Have a read multiple complaints concerning this issue on the smart blog. Possible electric shock issue as well as all electrical and lights out.

Where do I begin? After about a year of owning my smart car, I was driving on the highway doing about 70 MPH when suddenly I feel my car pull to the right and start shaking. I pull safely to the shoulder to find the valve stem for my tire had detached and my tire was now flat. Not having a spare, I had to call a tow truck. The same issue happened to the remaining 3 tires in the following months to a year. While driving the valve stem would detach and all air depleting from the tires. I called the smart dealer to be told this was impossible because the valve stems were bolted to the rim, well clearly not since it had happened to every tire.I have had multiple cylinder misfires with this car. I have had to replace the fuel pump. I have had to replace the alkaloid timing sensor. I have had to replace the blower motor for my heat and A/C. My headlights go out every other month. Car has stopped because a wire came loose in the battery. When I turn right or go on an onramp, I hear this awful clunking sound as if something is hitting a tin. When I go over bumps my car makes a squeaking sound. When going from park into reverse...car will not go into gear. My car will read p and n. I have to turn my car off/on multiple times as well as mess with my shifter for about 5 minutes before I can go anywhere. The cherry on top happened today on my way home to akron from columbus. As I am driving on the highway with a semi truck behind me my car started losing speed, even when pushing the gas. I almost was struck by the semi due to the sudden decrease of speed but thankfully was able to pull off the highway. Once stopped, all lights came on and car shut off. Put my car in park to try to start my car again, nothing. My engine will rev but the engine will not turn over. Will find out what that is tomorrow hopefully. Car was brand new when purchased and bought the car 5yrs and 1 month ago.

The 2008 smart car, has been consistently, shifting into neutral, while driving, usually, when entering, or exiting a highway, or at an intersection (speed changes). The car shifts into neutral, and then usually shuts down, causing the vehicle to be rear ended, from unsuspecting drivers behind this vehicle..the problem started when the car, would not shift into reverse, while parked..smart offered a software fix, to address that issue. Had that done, then problem progressed, to shifting to neutral while driving, and stalling out...at times car, would restart, but it would not shift into gear, indicating only a flashing neutral position. At times, car would not start at all, because would not know what gear it was in...if waited 10-20 minutes, or several hours, it might restart, and shift, for a short period, before it did the same thing again...apparently it's a common problem, with the smart car forums, full of complaints, about the 2008 year, with smart co., at times, authorizing repairs, and replacement with 2009 mechanisms, that do not have the same problems as the 2008 model year. There should definitely be a recall for the 2008 smart car, model year, before someone is killed, entering, exiting a highway, at a railroad crossing, or at an intersection, where the car, shifts into neutral, won't shift out, and shuts off... Thank you

I am having a problem with my 2009 smart fortwo passion's transmission. We picked up our car on saturday for the following problem: I was driving along & all of a sudden, the car seems to think it's in n. Even changing the gears prompts an "n" in the gear position. Once I turned the car off, it wouldn't start again & the dreaded three bars appeared. We tried the "teach-in" fix & it worked temporarily before acting up again. We had our car towed to the dealer for service and picked it up on saturday after the service department supposedly fixed it. The service department did a diagnostic check and a code appeared. They then reset whatever need to be reset for $112.98. We were also offered a software upgrade for $75 on the basis the service manager did not know what the upgrade does, but he did know it wouldn't fix the problem. Obviously, we turned down the upgrade. I have contacted mercedes to absorb the cost of fixing this defect. Our warranty expired only 6 weeks ago. Since there is a method to "limp" to a safe place in the user manual, it seems they anticipated this problem to begin with. From reading blogs about this, I was not surprised when the same problem started again on sunday. Now we are having it towed in for service again. I urge mercedes-benz to activate a recall on this model! Sooner or later this defect is going to kick in on the freeway and someone will be rear-ended or even killed. This is not simply a nuisance malfunction!
