Read the whole thread. There is a recall:

 

Hyundai stepped up, it's a recall for almost a year now

 

I am amazed to read that cars are driven until rusty suspension components collapse. Is this in the USA? Don't you have regular safety inspections?
In New Zealand we do an annual Warrant of Fitness (WoF) inspection for the first 5 years then every six months after that. Rust is certainly looked for. Historically it was in fixed bodywork, sills, pillars etc to cause WoF failure.
But we don't salt roads as a rule. In UK the annual MoT test is tough and in Germany the TUeV test even tougher. Both use copious quantities of salt.
I believe that in Germany, welding up rusty bodywork is forbidden, and the INTERIOR of structural members is inspected!
So why the collapses? A good, regular inspection should avert such a crisis I would have thought.

 

I use a product called POR-15 on all my Jeeps, and i'd advise everyone to use it on their undercarriage. Just take off the surface rust with a wirebrush and apply it with a paintbrush to the entire undercarriage body and chassis. I guarantee you'll never get a drop of rust anywhere again.

Unfortunately frame and chassis rot are very common, especially the lower you are to the ground or if you live in a region where rocksalt comes into play. My Jeeps almost live underwater, so as soon as I noticed the surface rust was becoming more prevelant I used POR-15 and the undercarriages still look new.

Don't drive it until it is fixed. My son was driving his 2003 elantra 55 mph down the hwy on Friday, Sep. 17, and the control arm broke. He came to a screeching halt and was able to safely stop the car on the side of the rode. Skid marks 30 ft long. When he got out, the right front tire was sideways! If anyone had been behind him, it would have been a terrible accident. Our mechanic is coming to look at it today to see if it also blew out the transmission, because it wasn't working after he stopped the car. I can't believe that anyone could make such a major part of the car so cheaply!

 

Here is pic of the replacement style arm with the added holes marked with red arrow for water to drain out...

 

After seeing the picture that someone sent me of a control arm, I don't think that is what broke. This was a thinner piece. The guy that stopped and helped my son, said it was the A-Frame that broke. Still waiting for mechanic to come and look at it.

Mechanic said it definitely is the control arm.

UPDATE: Monday, Sept. 20, 2010
I talked to Hyundai today. She said they would replace everything that was damaged due the control arm breaking, at no cost to us. We do have to haul it 80 miles to a dealership, but we have a friend with a truck and trailer. After paying $250 for a uhaul truck and trailer to get it home, this will be a great help. We can't get to the dealer for a few days yet, and the dealer said it was going to be a long process. Thats fine, as long as we don't have to pay to fix everything. I sure hope that's how it works out for us. I'll keep you updated.

 

The picture above is of the lower control arm (AKA "A-Frame").

 

Mechanic said it definitely is the control arm.

 

Is this car at the Hyundai dealer getting your FREE set of revised control arms installed by Hyundai Technician, and subframe drilled for inspection/coating applied or replacement if needed ? (Recall says if hole in 1 arm, replace both, comes as a kit)

Or is it at a mechanic of your choosing ? He will not be able to do the recall as specified, be he can buy the arms and charge you to install them..
