I purchased my 1999 Sonata from a used car dealer & have had numerous problems with the car, its been a nightmare, one problem after another!!!! the crankshaft sensor had to be completely replaced because the component had severely melted, issues with the transmission, ABS/airbag warning light on, & have had to change out the half shaft on both drivers/passenger side, numerous tires, brakes but the most severe of all the problems which puts my safety, my 12 yr old son & fiance's safety, along with family/friend's safety at risk is the complete corrosion of the subframe I too to a mechanic today & he told me to not drive this car for anything because it will result in an accident where I can potentially end up hurting myself or other innocent bystanders because Hyundai made a defective subframe especially for us that live & drive in hazardous conditions of the wintry/icy elements for 5+months out of the year in upstate New York!!! I will be calling Hyundai's customer assistance ctr & fuccillo Hyundai(local dealer)& the attorney general for New York. I cannot imagine what could've happened if I drove over a pot hole resulting in my tire(s) falling off especially if I was on the expressway doing 55mph my loved ones or other's loved ones, & myself could've been severely injured or worse dead due to Hyundai using a subframe that would severely corrode the subframe especially in the "snow belt" states!!!!! I just hope that I do not have a difficult time having Hyundai fix the problem in a speedy fashion without trying to strong arm me into paying for repairs that I am not responsible for because it is an inconvenience being without a vehicle now until it gets repaired.

While driving on I75 from naples, fl to ft. Lauderdale, fl, the driver side left front tire blew at 70 mph. The tread that meets the pavement separated from the sidewall. This tire is a kuhmo 195/70 R14 90H model 722 original factory tire on my 1999 Hyundai Sonata with only 25,000 miles on the tires. Before any road trip, I check tire pressure for safety purposes. My car body hit the pavement a few times before coming to a stop resulting in left front fender damage. This fender will cost around $700 to replace. I feel very unsafe with these tires and the cost to replace all 4 tires is around $300. This was a very dangerous and frightening situation, not only for me but also for the other vehicles passing me on the highway as the car was vibrating violently as the tire blew. It was all I could do to hold on to the steering wheel and keep the car in my lane as the car came to a stop. I sent an email to kuhmo via their website and have not received a reply.
