Engine was replaced per extended warranty regarding recall. Vehicle was taken into massey Hyundai on 09/07/2019 and returned with reman motor on 09/12/19. Since then the vehicle has showed over heating and the backup camera displays a white screen on 10/09/19. Called after temp light came on and Hyundai has the nerve to say they will not pay for the tow. On top of that they person who answered the phone explained the wiring harness wasn't replaced. Temp light hasn't came back on due to my son not using the A/C. NHTSA has not held Hyundai or Kia accountable for issues they no doubt knew about. The recall should have been a buy back for these motors. We are not asking for a new vehicle. We just wanted the vehicle working properly. Now my son is stuck with a vehicle with all kinds of electrical problems due to Hyundai flaw. The electrical system was working fine prior to the engine replacement and Hyundai should be held accountable. NHTSA is starting to frustrate

I bought this car 3 years ago. Ever since the day I bought the vehicle, it makes loud clicking noises when you turn the steering wheel left or right while in drive and reverse. In the 3 years that I have owned this car, I have had to replace the tires 4 times, the brakes and rotors multiple times per year, tie rods, and cv joints and yet the car still clicks when you turn. I had the engine recall done in may of this year. They gave me the car back a month later. I had to take it back the very next day because it was leaking copious amounts of oil and making a clanking noise that was not present when I left my vehicle with them for a month. They "fixed" the oil leak and told me the noise was from my front brakes yet again. I had to return the car again a few days later because it was still leaking oil! so they "fixed" the leak a 2nd time and again said the noise was from my brakes. Less than a week after that the check engine light came back on. I immediately took it back and was told that it was just a "loose gas cap" which I never experienced prior to the engine being replaced. They cleared the light and sent me on my way. I had brand new brakes and rotors put on, again, and yet the clanking noise is still there. 5 days ago, the car began driving the way it was before the engine recall, same engine failure symptoms and my check engine light came back on a second time 3 days ago. I have not had to fill it up with gas in 8 days so there is no way that it is from a "loose gas cap." My seat belt locks up and stays locked up if I lean forward. I should also mention that when I bought the vehicle I had to inform the manager that the front bumper was only attached to the car because someone drilled screws into it to keep it on. He had no idea!! I made them replace it before I would buy the vehicle. The paint is constantly chipping off of the "new bumper" they put on it.

I got no light signal warning me about oil or engine, it just started the noise so I stopped driving it so no further damage was done. My car lights never came on ever about my oil or engine.

I have only had the car for about 6-7 months I bought it from a private owner I changed the oil and bought a new battery. The car did high milage at 194,000 miles I still bought the car. Last week while on my lunch break I was in my way to go pay my car insurance when I seen I had 32 miles to empty which I never let it get that low but I did obviously that day. As I begin to go up hill it felt like it stuttered so I figured I was running out of gas. But as I came over the hill I press on the gas and noticed that it revved up and to my knowledge the car was locked up the steering wheel was not able to turn the breaks were locked up and all my dash lights were on. I was scared and just let the car coast down the hill approaching a red light with traffic stopped all I could do was hope I didnt get it or hit no one else for not having much control over the car I braked as much as I could and coasted it into a gas station to where. I made it to the pump and turned the off off and went and got gas for the car. Tried to turn it over and not a thing happen sounded dead battery like it wanted to start but once I turned the key and it did not start if I tried right after just made a click click noise. I took my battery out and home to charge thinking maybe a bad cell or maybe alternator. Bought new battery and it not start so no not the alternator. I am at lost for words tried to turn the crankshaft and wont budge. Am I able to still get this looked at by Hyundai even if I just bought the car. Its registered to me if it is caused by these recalls does the car have to still be running for me to be able to recieve the benefits I have never had a car just straight die. Never made any noise or smoke or got hot. Also I noticed when I have the key and drop it down into all the gears it goes but when I slap it over to the manual side I can go from 1st to 2sd and that's it.

I bought this car in 2013 for the Hyundai dealership in gurnee il. Since then I have had nothing but recalls, and issues. All of the recalls for this year and affected my car as in the warning they way may happen actually happen to me. My engine seized up while I was driving with 2 kids in the car on a busy street and I was almost re ended as a result only to have the dealership tell me it wasn't the recall! then later they had to fix it after I work to corporate because it was the 132 campaign recall. The 3 dealership I have dealt with are all rude none want to actually fix your car or help you because its recall work not actually work that they make money off of. Now as of today my airbag light has come on after the "fixed" the newest safety recall, when I called the dealership they informed me they fixed the issue so I will be charged $139.99 for them to even look at it. When will Hyundai be actually held responsible for all of these car issues they are all safety. So far the recalls have been for the engine, seat belts, brakes, air bags, body corrosion, and so on! I thought there was lemon law in place to remedy this, Hyundai product faulty vehicles with the model year 2011 and the consumer if the one lose and spending out of pocket. I had even called corporate before this to try and remedy the issue myself and was told they are sorry some will call in 3-5 days. At this point I am a mother driving around with children in a vehicle that may or may not pop the air bags whenever it feels like or they will not deploy if I do get in an accident. Something needs to be done with these cars they are not safe to be driving at any given time another recall can cause a major safety related crash or death at this point. I have had way to many close call with myself or my kids lives at risk due to Hyundai lack of care for their consumers.
