My axle nuts are seriously corroded, to the point they no longer look like nuts. I'm very concerned the axles may separate from the wheels.

The contact owns a 2005 Hyundai Tucson. The contact stated that while making a turn at 20 mph, the vehicle stalled without warning and the steering wheel became difficult to maneuver. The vehicle was able to restart after waiting. The failure recurred intermittently. The vehicle was taken to the dealer where the failure was unable to be determined. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 81,000.

Letter to nstb and MA attorney general, re Hyundai underbody corrosion on 8/6/2015 I received a Hyundai "service campaign notification" on my 2005 Tucson for "under body corrosion." I did have the recall service completed. ('arrests' it, they claim, but not removes it.) by that date I had already experienced two failures caused by the corrosion, both of which I believe had high potential for serious, even fatal accidents. The repairs cost almost $2,000, but they refused to reimburse. I am more concerned with the safety issues. Luckily, the fuel tank falling onto the drive shaft did not rupture and explode. The right front control arm failure caused loss of steering control and an abrupt stop into the right curb. Had it been the left front, , I would have been steered into oncoming traffic. Had it been at turnpike speed I suspect a likely rollover. The left front arm was also near failure. I sent two emails to Hyundai, and made a number of calls, in part requesting repair reimbursement, but more importantly to tell them my concern the car was unsafe to drive. I asked them to buy it back at a fair price. No response. Twice, they promised to contact me in 2 to 5 days, they didn't, ever.. when I later called them and told them I had sold the car (at a loss in value) they just brushed me off. (to paraphrase them: 'it's no longer an issue since you now don't own it'). I can provide documents (repair invoices, with findings, and emails if you wish). I am requesting you take action to investigate, and as needed, take action to issue stronger sanctions against Hyundai, they should be forced to recall all the affected cars.

2005 Hyundai tuscon, rear sub-frame completely rotted out. The garage was shocked to see where the 4 bolts are to hold the crossbar completed broke off! while driving on the highway at 65 mph, and changing lanes the vehicle seemed to have a delayed reaction or like it was "fish-tailing". the incident didn't happen on the highway, however when turning a corner on my street, suddenly a loud rubbing sound and grinding sound happened and the vehicle waved side to side while trying to drive it up the street. The steering was extremely loose and it felt like it was going to crash into the side of the road on the curb. There was rubber from the tire on the inside wheel well on the piece that covered the shocks. Hyundai replacement parts is almost $1000!!!.....updated 10/01/15

While driving in the rain the battery light and brake light come on, the steering wheel freezes and power seems to lessen in the car. After a few seconds the steering resumes. Has occurred during a turn, making the car go straight. There is no power over the steering when this occurs, however, the brakes do work. The steering wheel becomes extremely rigid where it cannot be turned. Has happened on at least 3 different occasions. Almost hit by another car three times. The car has been taken back to the dealer two other times with no relief. They do not seem to know how to fix it. I have seen this on this site under steering: Hydraulic power assist system.
