Tire Pressure Monitoring System problems of the 2013 Hyundai Elantra

I am the original owner of a 2013 Hyundai Elantra gl with hankook optima model 426 205/55r/16 tires. I did all rotations at 6000 miles and alignments once a year as the car manufacturer specfies. This vehicle is also equiped with a tire pressure monitoring system (tps). Which never indicated any problems with proper inflation. Even with full tread these tires had almost zero traction in any weather conditions were there was any accumulation of rain or snow. These are stated as all season radials and they do not preform as such. My tires were down to the wear bars 3/32' tread left with 29791 miles on the odometer. The manufacturer lists these as 50,000 mile rated tires. When I questioned Hyundai they refered me to hankook telling me the manufacturer knows all about the problems with the tire and is handling all complaints I contacted hankook customer service at 800-426-5665 and spoke with jeanette at ext. 616 I was first told all I needed to do was have a one of their local tire distributors verify tread depth. I had the tires replaced at town fair tires. Then I asked the manager at town fair tires to call them to verify. Which he was happy to do. The story changed two days later the manager called and was told they didn't know what he was talking about, he called me I called them and then they remembered the conversation and said" they would call him back". Then he was told they needed pictures emailed to them of the tires. An hour later I was told by hankook they need the actual tire skins. Since it had been three days since I had the tires replaced the distributor's recyclers had already picked up the tires and they were no longer available. All I was looking for was the industry standard tire allowance for lack of preformance. Which now they are refusing to do for me without the tires. Can you help me? these are dangerous products on our roads and need to be removed.

I bought my 2013 Elantra on 7/17/12 from orlando Hyundai. On 8/4/12 while driving on I-95, the tpms (tire pressure monitoring system) light began to flash. I immediately pulled into the nearest tire shop and had the tire pressure checked on all 4 tires and they were all fine. The mechanic suggested I have my dealership take a look and possibly have them reset the sensors. Upon my arrival home, I took my car to the dealership and they were unable to provide a reason for the sensors going off. The issue persisted for several months causing me to spend countless hours at the dealership. They even went as far as to keep my car for over a week, drive it several miles and replace the entire system including all four tire sensors. Despite this, the tpms light still flashes. They have attempted to convince me that usb and aux cords in my car (used with my phone) are causing a signal interference with the sensors. In my opinion that is a bogus excuse. The car should not have the features if they are unable to coexist. The dealership has also attempted to reassure me that nothing is wrong with the car and it is safe to drive even while the tpms light is flashing. I do not believe this either as I constantly have a safety feature alerting me to believe otherwise. I have told the dealership and Hyundai headquarters that I believe this car is a lemon on several occasions. They informed me that a car is only a lemon after having the same issue fixed 3 times. Thus far I have had my tpms fixed twice. I do not feel safe at all driving this car with dysfunctional features.
