SmartCar Problems Mercedes Can't Fix
I bought a Smart Passion 2009 last May. First car I've ever bought. Great deal. I LOVE it. I believe it is a model 451?
Last Summer, my dad wanted to check the anti freeze for me, he didn't drain the line. He let the car run for a good hour or so to pump out the air bubbles - he knows it wasn't the best idea, but thought it was okay, didn't know a whole lot than about the technology in a smart...
The car over heated on my way home, and shut off. All of the lights went on. I don't recall the temp light coming on first - he says it had to of, and that I missed it. Never the less, Mercedes told us than that the pistons were warped, due to all the parts being so close together that the anti freeze got into the engine, warping the pistons when it over heated. Car Done.
Mercedes said $10k CDN, for a new long block. The car cost me, $4200.00 CDN. That was in mid August 2018. The car is in really decent physical condition. My dad is a bit of a mechanic and felt really bad, and wanted to fix it for me. He has rebuilt engines all of his own vehicles, boats, motorcycles, before... but a smart is different.
By the time he got back to my car, it'd been 5.5 months - the idea was to find another engine to place in, or rebuild and fix the pistons, but I guess he forgot, and rebuilt the head gasket.
***The car turned back on, and seemingly worked for him. He could start it and drove it around. I picked it up, and it took longer and longer for it to turn on when trying to run the motor (sorry I'm not technical/mechanical at all) but dad didn't see anything wrong with it, and I took it. Back home, it wouldn't start, needed a boost, we thought it was the cold, but you know running it all over town for a good hour, shutting it off, and than restarting - it wouldn't restart even with a warm engine.
Dad took it back to Mercedes, apparently they said something about the head gasket, so - hence he fixed that... but than they're still saying it's the head gasket, it is leaking out the top, I guess due to the pistons being warped.. They also mention, that once the pistons get warped there is really no coming back from it. Mercedes mentions low compression hence the pistons.
Dad tinkered and told me, it's fine, it works, he puts the key in, it turns on, he runs around in it. I took it again, and used it 6 times in a row. With every time it took longer and longer to turn on.
Dad feels that if it were the low compression, the car wouldn't start at all. He feels it is something else. Thoughts?
Over all, I really am thankful for my dad, but at the same time, I wanted a newer version, and I wish I'd waited just a little bit longer, to buy it. I've put nearly $2k CDN into it, as it had another issue, and dad didn't have time to figure it out - thus far all the knowledge dad has about the mechanics of vehicles haven't really helped here with this smart car. He's spoken to other mechanics, and he may be dropping it with a friend that is a studied mechanic - hot rodder - mercedes
Also, I'd love to bring it to the mechanic that fixed another issue on the car, but cost me an arm and leg, seeing as I paid practically nothing for this car. I can't afford to. I haven't been able to get steady work since the car died last August.
My dad is going to check the fuel pressure on the car, he thinks maybe it is the fuel injector??
This last time that I left the car with dad, he couldn't always start it, but than after he'd left it for a day or two, he put the key in, and it started...
Might anyone have any other idea's about what we could check?
Thanks in advance!
