I'm getting quite livid honestly. While I did purchase my car used I feel I shouldn't encounter all these issues. I've been having this issue where occasionally my car will do this weird jerky motion forward after a stop and it just did it about an hour ago where it did this then it would NOT accelerate. The vehicle gets jerky going from first to second gear. I put the car in park then tried to turn it back on to try and get around this but the car wouldn't start, and by start I mean no turn over. It would just click and nothing. I drive in automatic so not sure what's going on. I had to put my hazards on in the middle of a roadway to wait for someone to come help and I had some people push me to the side of the shoulder safely. After about 10 minutes or so I kept trying to turn the key and it finally ended up starting. Any ideas what could going on? :( This is my only way to and from work, with no other alternative ways of transportation and I don't have funds to throw at the car and hope for the best.


I did have an issue where my car did this before and the CEL came on and told me something about clutch actuator sensor or something along the lines but it seems that the light just went away.
It's a 2009 Smart ForTwo Passion with about 73k miles on it last I checked. Dealership has it's last service date back on 9/19/2018. Claims it had "new tires" but the tire pressure light comes on every other damn day.

Welcome to SCoA.

MY09 tire pressure light - could be a product of cooler temperatures or sensors (dead batteries?) needing to be replaced? Any competent tire shop should have a tool that can test the TPS?

It is semi colder here, mid 30s. As for testing the TPS. I do have a local tire spot, no idea if they have one or not. I could check though.


...how old is your battery???
...check all the grounds ...the battery and in the battery box too...just because it will not turn over

Jetfuel...Next...

I assume it's the stock battery it came with? I've done no maintenance on the vehicle since getting it. Wasn't aware I'd need to if it came from a dealership and the sticker saying it was recent. In the battery box? Is there another battery? Sorry, new to this Smart.


Buy a new car battery. Push the TPM button on the dash to turn off, rest the sensor light.
Should I have the battery tested first? I've hit the TPM button after filling the tires to the required pressure. It typically comes back lol.


Likely clutch actuator issues. Hopefully it's just the actuator needing adjustment and not a clutch needing replacement. Taking your car to a dealer for a diagnostic at a minimum is a good idea.

How easy would adjusting it be to a novice? I know my way around some tools and can follow videos.

the tire pressure system is kind of picky. Make sure your tire gauge is accurate or use a digital gauge........also try a higher pressure like maybe 3-5 psi and see if it helps. Sensors typically will last 5-9 years with their internal batteries Maybe it is time for new ones. New tires does not mean 'new sensors' however when putting on new tires, it is a good practice to replace the sensor 'rebuild kit' it includes new stem seals, nut, core and cap. If the stem is damaged or thread is worn , it too can be replaced without replacing the complete unit

Since everything on the car is run through the computer, a good battery is a 'must have' as are clean tight connections.

Your new tires may have that stupid manufacturer sticker they put on the sealing bead still there . Tire installers are notorious at letting them on , and they cause small slow leaks . Check around your rim interface and see if there is any partial piece of one of those sticking out . Spray soapy water and look for bubbles .

The batteries in your TPM sensors might dying. There good for about 5 years, at the most. On one of my other cars. The sensors pickup receiver went bad. Had brand new TPM sensor, at all four corners. The dealership pulled a code, saying it was bad. A message would appear on the dash. Sensors can’t be located. The smart cars system. is not that sophisticated, like that vehicle. All you get is the icon, on a smart car. When they did replace your tires, they might have replaced the sensors too. With the wrong kind.

Light seems to went away after filling the tires to their proper specs, even went a couple of psi higher due to cold then I hit the The TPM button. So there's that mystery solved lol. Now to work on the rest of them.
