According to Kelley Blue Book, a 2010 Hyundai Elantra costs around $16,500. This is a highly rated vehicle, and is a great car for commuting. Hyundai is definitely an up and coming brand.
first of all do you have any dash lights coming on.(is there power from the battery)
If you have white smoke coming out the tail pipe and the smoke has a sweet smell to it, the car has bad problems.
My Hyundai Elantra 2008 GLS with 13,800 miles on it had a vibrating rattle especially when idling but also while driving although not always. I bought the car used. After four months of going crazy with the sound we found that it was coming from where the back seat joins the frame. It is not tightly joined there nor is it cushioned. We stuffed some thin cardboard around it to tighten it. That keeps it from vibrating and rattling.
Smoke coming out of steering box usually means the fluid is burned. It can also mean that the steering gear is failing.
2010
Crankshaft thrust bearings worn / dislodged allowing crankshaft to walk back and forth. Seal is pushed out the front of engine and creates Huge oil leak. By this point, the bearings,crank , and possibly block , have be damaged.
I also have a 1993 Cadillac DeVille and smoke is coming out of the steering wheel. wish I had an answer.
2010
Bad mounted tire, bad alignment, worn or damaged steering components (e.g, tie rods, spring pins and bushings, ball joints, etc), bad wheel bearings.
Through sound waves travelling as vibrations through the air.
There is no connection from the power steering system and the engine systems. The only conceivable way that power steering fluid would be coming out of an exhaust system is to have power steering fluid poured into the fuel line. Transmission fluid could be coming through a vacuum line. This may appear to be similar to power steering fluid.
