What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
My airbag did not deploy in a traffic accident. The car was total june 1, 2003.
I own a 1999 hyundai sonata and was informed by my mechanic that the front sub frame on the passenger side is rusting through, presenting a severe safety risk to the driver and passengers. There is currently a manufacturer's recall showing for the 2001-2004 model from your investigation.
1999 hyundai sonat gls airbag warning light continues to come on after being worked on by hyundai dealer 10-15 times. Was worked on without issue while under warranty with no success. Once extended warrenty expired, the dealer then knew that the car needed a new wire harness for about $1000.
Investigation revealed severe subframe corrosion resulting in the control arm mount separating from the subframe, causing the cv joint to fail and the vehicle to become inoperable. Nhtsa and hyundai issued a recall in 2009, campaign id number: 09v124000.
It has completely rusted out on the passenger front side causing steering control arms and drive axle to break loose from vehicle and making vehicle inoperable. This should be covered under hyundai recall campaign 089. Nhtsa campaign id no. 09v124000.
My mechanic noticed rusty area around suspension control arm, etc. Labeled it as a priority repair for safety reasons. I previously had the complete rear wheel hub replaced because of corrosion a few years ago, too. I have not gone to a hyundai dealer yet so I'm not sure how to proceed from here.
Just everyday driving to and from work, the usual speed bumps ( taken at normal speeds for said speed bumps) the steering pulls to the right, significantly, and the front right tire is at an angle instead of perpendicular to the road.
Upon inspection by the repair facility it was determined that rust to the sub frame and related bolts caused the failure. I was lucky that I was not driving faster.
