P205 65 R16 Blizzak tires were purchased in December 2023, online and I had them installed same week. I spoke to the employee who stated as long as I rotated the tires at 5,000 miles, I can drive them all year. I went to Discount tires on Saturday to have my tires checked since I was sliding in the rain. The employee told me my front tires were at a 1 and 2, while the back tires are at 9 and 10. She told me to talk to the front desk about the tires. I went in and asked about the warranty I had purchased. The employee told me it does not apply and that I would need to replace the tires. I explained to him that the car doesn't even have 5,000 miles on it since the purchase of the tires and how did the front wear so quickly? I only started using the car more in March. He also told me it could be the alignment. I had that fixed 2 years ago and the car doesnt pull left or right. He stated that the tires will bald if being driven in over 40 degree temps. I have in the past used winter tires all year and never experienced this. These tires never made it to 5,000 miles. They should not be worn so badly in the front, that this had now cause my back breaks to grind. Not only do I have to buy 4 new tires, since I can't keep the back on there, but I have to eventually get new back brakes, that aren't even 2 years old. These tires should not be on anyone's cars if they wear this quickly.

Hyundai Theta II engine has known defects with excessive engine oil consumption. Numerous consumers have complained of this issue as it appears widespread to the entire line of Theta II engines. A recent class action has limited the scope of the recall but an easy search can see it impacts (or has the potential to impact) nearly all Theta II (six gen) engines from Hyundai. The issue is that the scope of the recall needs to be widened to cover others who are impacted who currently have no recourse. Many are facing the same situation, which can easily be found with a brief search online. [XXX] At this time the issue is the car stalling at unknown times, fire from oil being displaced in other areas and various other issues due to improper and unusual oil consumption. The best situation would be to force Hyundai to review and expand the scope of their recall immediately. I found that I had excessive oil consumption which was causing my car to grind and shift heavily sometimes jerking on the highway. While I didn't crash, that possibility did exist when my car continually grinded heavy between shifting. I took my car to the dealer where they confirmed this issue. However, Hyundai declined to remediate. There are no warning lights and this could easily result in a crash, or fire. Hyundai has records of my maintenance, as my car is only serviced by the dealership where the car was purchased and I am the original owner.

When Driving the Alarms go off indicating a brake issue, my brake peddle goes to the the floor, car looses power and slows down to 5 MPH. Car will not accelerate past 5 MPH when i am trying to pull over or get off the freeway. Brakes are grinding as i try to use them, very dangerous while on the freeway. When I am able to pull over. I will turn off the car and turn it back on and the issue goes away. Now this may happen several more times before i am able to get some where safe. Dealership has no clue why its doing this after showing the video of the Alarms and describing it. No codes are found either. They just want to start replacing parts stating at 3k a round hoping it will fix the issue. This issue doesn't happen every day but it does happen while driving on the freeway. I have read online others having the same safety issue while driving and having thes same brake failures. Not sure where Hyundai is at with this issue and the fix for it? Yet does someone have to be in a serious accident before someone takes action with this issue?

I was driving on a side street, heard loud noise coming from left front wheel area when I heard a grinding sound and car was riding rough. Called for help.instructed not to drive vehicle till it was looked at by a mechanic. Mechanic who evaluated and repaired vehicle said he has never seen "pitted wheel bearings" in 30 years of operation. He gave me back the faulty bearings and told me I should contact you and the corporate area of hyundai, because this is a serious safety issue and warrants an alert or recall. The driver side lower ball joint and bearings had to be replaced. Please review asap, as this is a serious safety concern for the rest of the population. Thank you!
