Exactly 7 days ago I bought a 2009 infiniti G37 from a dealer. I love the car. Last night I started it up and something on the exhaust broke. I talked to the dealer and they are fixing it no charge. I looked under it today and found what was loose on the exhaust. I also found really bad rust and am wondering what part this is so I can tell them to replace it. Also wondering if it is safe to drive

 

Front cross member? It's kind of hard to tell.

 

Poke it with a screwdriver if it pokes through then no

 

And if that is the front cross-member, yikes!

 

After doing some extensive research and looking at it better, it is the front crossmemeber k frame and I did poke it and hammer it and it wasn't as bad as I originally thought. Still pretty solid but I am still going to demand the dealership replace it. They are already fixing the exhaust that broke and my steering wheel switch that doesn't go back up. I bought it from carmax and they guarantee that they don't sell vehicles with bad frames or frame damage. I'm pretty sure this would qualify.

 

Make sure they realign car as well after

 

That doesn't look like the K frame(Subframe), it looks like the cross brace on the AWD sedans...you can drive the car without it fine, you may just notice it doesn't handle as well...maaaybe... anyways it commonly rusts, I think most ppl just pop it off (comes off with 4 bolts and nothing is in the way) clean it up and spray it with some paint...used replacements are cheap too if you're making the dealership do it
