Is this normal with these cars or is something wrong??

With Traction control on the cars doesnt move AT ALL on SNOW.... If you turn the traction control off the car moves decently (since the stock tires suck @$$) but theres a loud thumping noise as your driving.

Any idea?

Ehh could be shocks/struts or something similar sounding like that with it being cold...

Check to see if you have snow built up in the wheel wells, that's another idea

I have had that happen before.

Or your car has been sitting a long time? Possibly a flat spot that will even out when your tire heats up.

Nope. Just picked it up from the dealership last week. They picked it up from illinois and drove it to michigan.

Its driving me nuts. I hope it goes away. and I hope its not the LSD messing up.

Took car out for a cruise on my lunch and found some dry pavement. Traction on or off it didnt make any knocking but back at work I turned the Traction control on and made a left turn/circle and it started knocking again. Not sure what it is but havnt gotten any answers so im assuming it hasnt happened to anyone else.

I don't have an LSD on my car so I couldn't even tell you if it makes a noise at all..

Definitely bring it up with your local dealership. They might know what's up :)

If the traction control is on, I bet that's what the noise is. I.E. the TSC working or braking(however you want to look at it). Do the same thing(left turn/circle) with TSC off. I bet you just spin out with no knocking.

EDIT: Also, the stock tires are also summer tires(R-Spec and Track). They are not made for snow.

My R-Spec makes some crazy noises in the snow as well, but you're a bold man driving it around without the traction control. The noises do go away though as soon as the car has warmed up a little.

Are you saying I'm bold or the OP? I'm not starting a fight, just curious. Me personally, I try not to drive the car in the snow :D. If I do, I drive with TSC off just because I like to be able to predict when the car will lose traction. With it on, you never know and, IMO, the Genesis' TSC is awfully programmed.


Just my .02 cents.

I was just saying you were brave for driving with it off, cause I won't even dare do it. Most of the time I won't drive in the snow unless I absolutely have to.

I figured it was just the LSD but wasnt sure if it was normal or what was going on. The car only have 1,000 miles on it.

I dont drive on the street with the traction control off unless I get stuck. If you get stuck in the snow with the traction on you wont be moving anywhere until you turn it off.

I was just driving around in my work parking lot testing it out with it on and off. Doing some donuts here and there to see if the knocking would go away.

I do agree thou. I like driving with it off sometimes when the roads arnt to bad. I love drifting a bit when It can be controlled, otherwise traction stays on.

So did you try the donuts with TSC off? I'm fairly certain that the noise you were hearing/feeling was the brakes trying to control wheel spin. I have heard something similar when there was snow on the ground here. All in all, if the noise persists, take your car to the dealer.

time to get a lsd
R-spec has an LSD, and please research before posting uninformed comments has such.

The LSD in the GC won't give you that much better traction on icy/slippery roads, in fact it can be the exact same as a car without an LSD.

it would do it without even hitting the breaks unless you mean the traction control applys the breaks automatically which ive never heard of. from what ive figured out its the lsd trying to slow down the spinning wheel to prevent spinning out. going in a circle / sliding aka donut it would make the noise or if you just give it gas going straight it would do it. dry pavement with traction on or off it didnt make the noise. i asked the dealer and they said its normal. just the lsd doing its job.

Your ESC is part of the ABS system. So yes, the brakes will be applied slightly without you touching them.

Dude, really? Stock RSPEC (read, summer/performance tires) in the snow? Of course you're not going anywhere, you're a moron.

Sorry, but you are. Park the car until you get winters on it.

As for the sound, could be anything the other guys and girls have mentioned: flatspots especially likely with the SUMMER PERFORMANCE TIRES IN THE COLD, could be bad suspension, could just be the traction control.

But yeah, the first thing you need to deal with? Not being a danger to everyone else on the road, and lose the summer tires in favour of winters. Or park it.
