    Hello all, and thanks for your help in advance! I’m new to the Smart family as I just purchased a 2009 Smart Brabus. The maintenance has been super easy so far (changing oil & changing transmission fluid) but there’s a weird squealing noise at low speeds while turning mainly. There’s no kind...
  2. Engine noise

    smart Operation and Maintenance
    I've recently put an engine from a salvage Fortwo with around 40k miles on it and 2 days after the install it started making this sound. I'm not sure if it's a belt or pulley because those came off of the old engine that had been sitting for 2 years but it makes this sound on cold starts and...
  3. Strange Scary Loud Noise (subwoofer)

    smart General Discussion
    I have a Fortwo Cabrio Passion, 2008. It has been in storage for three years but I got it back about a year ago. I had it checked out twice by dealerships and it was given a clean bill of health. However, lately there has been a really strange noise. When turning it over there was what I can...

I live in CA and we really have not had any rain since April til last night, so I don't know if the humidity has something to do with it. This morning after going to the grocery store I...

    Transmission noise (whine)? [updated] After 48k of blissful ownership, my smart has suddenly begun to exhibit that not all is good with the drivetrain. I bought the car to commute, and it sees 110 miles each day, M-F. I routinely maintain the car, with OCI every 5k miles. As of last week...
  6. Weird harmonic noise (wind)?

    smart fortwo (451 - US vehicle)
    On my '09 ForTwo pure, I have this recurring weird noise. I have noticed it sometime after 30k (36k presently on the odometer), and here is the only way that I can classify this sound: - Occurs at 60+ MPH - Occasional noise. Occurs weather it's windy or not. I can hear the noise especially when...
  7. Engine noise

    smart Operation and Maintenance
    While warming up the engine for an oil change, I noticed a periodic noise, kind of a ratcheting sound. I looked and it seemed to happen in sync with a rotating part on the right side of the engine. This part is a small wheel with an arm attached to it that rotates back and forth. It possibly...

    Hello! I have been a lurker for a while, but now that my 2009 Carbio came in last week, I spent the better part of this weekend installing a new stereo system and I am having an annoying little problem that I hope somebody might have a recommendation for. First, a little about my system. I'm...
