Hello, my smart car has the following problems, I will fix them soon, just posting here for documentation.
Radiator condenser fan broke off housing at 86k miles
HVAC Blower motor intermittently blowing at 90k miles
Convertible roof sliders got stuck at 44k miles
Undercarriage splash shield just fell right off recently, probably user damage
Cargo light sometimes does not go on when opening doors, switch on right position
Cabin air filter starts smelling bad at 95k miles

Why does Mercedes have bad motor designs and bad convertible designs? Why does the transmission shift like a narcoleptic turtle? Any way to fix the transmission slow shifting other than getting an rpm meter and using the paddle shifters? Why do the shocks feel nonexistent?

Otherwise, this car has been really good, 63 miles to the gallon, yes, sometimes even 75 on long highway trips. Handles very well.

Splash shield doesn't just fall off - been off roading much???

And after almost 10 years your Cabin Filter is smelling bad - an Annual Service item, might want to change it???

Just fix your "problems" not sure why you feel compelled to post to SCoA "for documentation???"

Might want to change out your cabin filter, for a new one. 95K on the original?

63 -75 mpg. Are you sure your driving a smart car?

The Transmission shifting is normal, for a semiautomatic.

Replace your blower motor. Rock auto carries them.

Short wheel base cars, don’t absorb rough roads. Not enough rebound between the front and rear tires. Replace your old worn out shocks.

Welcome to SCoA! :D

You do appear to be from the States. Perhaps you can give us some more information so we can perhaps be of help? No 2009 smart in this country is capable of the fuel economy you are claiming! :eek:

Instead of documenting your service history and requirement here you might want to consider a notebook or smartphone. I use the Notes app on my iPhone to keep track of things like "top tracks needs lube" or "shocks need replacement" or "oil change due in October or at 40,000 miles" etc.

I think I've seen some apps that have service categories and reminders if you don't want to free form it like I do.

The transmission won't shift any faster. This question gets asked a lot by people who don't understand that the transmission is a robotized manual transmission, not an automatic. If you understand the engineering of the transmission you will be much happier with the car.

Welcome to the forum.

Lube. Will turn out to be the most underrated service to preform on Smart Cars.

As fellow Smart drivers engage me and talk about their cars, when I crawl under their cars and and look at all that rust and crud of the chassis pivot points it reconfirms my mind that Lube to exterior parts of the Smart is crucial to a better life for car and driver. As stiff as some of the cars are that I have seen it could easily lead to rattling the car to pieces due to the undue stress and harshness of the frozen suspension. So things will misalign, rattle, crack and come apart prematurely with out lube to soften up the ride. Looking at a blower motor design I can see it may even benefit from a spritz of lube. "paulbob" even reminds that the roof sliders need lube. Yesterday while under my car I could see my Steering knuckle could use some lube (surprisingly thin steering steering system).

(Note. My car was damaged when I got it and the front belly shield was mangled, I removed it and have not replaced it. I feel no ill effects and remember I am doing long distance high speed runs as well as daily city driving. I mention this only because many of the bushings and pivot points that are in need of lube are hidden by that front shield. I have yet to remove the rear belly pan but intend to the next time I have it on a lift to see what I find. Hopefully that wont be until June)

So as part of maintaining our Smarts don't over look Lube.

You should feel lucky if you have access to a lift. Many of us don't have a lift, and some (including me) don't even have access to a garage or even an area to park that is not on a road. After putting up with on street parking and planning to get around to building a garage for 22 plus years, I think I will give it up.

Nothing wrong with periodic maintenance and as you said, a little lube goes a long way.

Hello everyone, I saw your replies, thank you for the tips.

Yes, my smart car runs 63 to 75 mpg, but it sometimes goes as low as 35 mpg on windy days and multiple stops. It's true, for every one of the black bars I get 63-75 most of the time, one time, i drove the car to Missouri, which was 300 miles away, used half of the tank, 600 miles round trip, and it was able to go back without refilling, anyways, this is especially concerning.

I have ordered all the parts already, the reason why I posted here was to inform people and get answers.

I will not be ordering a blower motor, instead, I will be cleaning the contacts.

I have no personal lift . The local shops that I use indulge me when the car is on a lift for one reason or another and 10 dollars would get them to take off the belly pan and let me have a look. I to am a street parker with no garage at the moment.

Is your car somehow a diesel? No petrol 451 I've ever heard of gets 600 miles to a tank. This site's old hypermiling champion got somewhat close to the low end of your numbers, but it took him driving in the wee hours of the night driving a steady speed under the speed limit to do it.

I'm not doubting you, I'm legitimately curious! :D

Yes, gas motor, 91-93 octane, what would you think is wrong with the smart car since it's getting 60+mpg?

In this case, I would say you have the most fuel efficient smart in the USA. :D You're getting more than double the combined fuel economy rating. Most people get something like 35 mpg under normal driving conditions with few people breaking into the 40s. Back when I cared to hypermile the best I was able to do was 50 mpg and 400-420 mile tanks. I can't imagine somehow getting 600 miles out of a tank, so consider my mind absolutely blown!!

Perhaps because on Fuelly.com 322 MY09 smarts driven 5,702,438 miles are averaging only 37.2 mpg???

And if you happen to live in AZ 85719 and run the air conditioning - "63 to 75 mpg" is simply impossible.

Ooooh, an odometer somehow counting in km would account for the discrepancy. It's normal for the first bar to last 80 miles (on one hilariously full tank I got it to last 120 miles) but each bar after should be like 30-35 miles. Converting that to kms matches up the mpg claims. But then IIRC, the dash does tell you what unit of measurement it's set to, so...:shrug:
