when the car is cold it would not start. I checked what the problem can be online and it turns out that there are a lot of out cars with the same problem. The problem is starter. sever people after changing the starter there vehicle was fixed. Another problem is sometimes the blind spot warning system does not work. These problems are reported by people with the same car but not by dealers.

UNKNOWN— Engine has been making noises, vehicle keeps breaking down (ENGINE ISSUES, alleged starter) and Hyundai dealerships keep ignoring and not documenting my complaints and passed the vehicle for all inspection after others have documented some of my complaints that I brought to them. They simply didn’t want to do any work because it was covered under bumper to bumper warranty until I threatened to call Hyundai USA with a lawyer and my engine problems were NEVER ADDRESSED or examined by the Hyundai Dealer in my area even though I specifically kept complaining about my car seizing and stopping on me in the middle of the highway with my toddler in the vehicle! It’s doing it again and no one at anything Hyundai cares! I’ve been lied to and passed on for over a year now and the problems list keep getting longer and longer! I was told that the Engine was replaced in March 2019 and that was that..I was dismissed! No more questions asked when I made my complaint directly to Hyundai USA this time!

I purchased my 2018 Sonata on 10/23/21 from South Point Austin with 30-35k miles on it. In the year of owning it, I've had 3 manufacture issues occur. Once on 12/31/20, there was an issue where my car detected an issue, and my maximum speed was 30 MPH while I was on the interstate. It was a sensor issue and covered by my manufacturer's warranty. On 11/11/21, I had to purchase a new starter for $789.26 despite this being a manufacture issue and covered by warranty. There was not a dealership in my area that would look into my car until 2022. They would not cover a rental until at least a diagnosis report came back which they would not begin until 2022. They said the lengthy waitlist for a rental would prevent me from securing a vehicle to use in the meantime. Because I need a functioning car, I had to purchase this out of pocket. On 11/23/21, I had to purchase a new battery. Again, this should be covered by factory warranty, but the dealerships would not look at my car until 2022. I paid $241.14 out of pocket for this. Setting the issue of these unexpected expenses aside, my car does not feel safe to drive and has had several manufacture complications. I had a near fatal accident in my previous Sonata do to a software issue causing the brakes to go out. This line of cars should be looked into for the safety of all.

ENGINE
2018 Hyundai Sonata sport. Purchased vehicle 03/20/2021 and it has been in the shop 5 times for the same issue. Car starts to smoke and make a loud knocking noise, when checking the oil, it appears to have no oil in the engine at all. Every single time they have changed the oil and replaced it and within a 1,000 miles the oil has completely dissolved in the engine. They performed a consumption test and stated that they did a top engine cleaning for the combustion and that it should not happen again and if it did that they would reach out to Hyundai to start the process of replacing the engine. Took it back at the 1,000 mile mark and they stated that it was fine, but after only a few weeks to a month the car started smoking and knocking again, took it back and yes the engine was bone dry again no oil at all on the dipstick. This vehicle has been in the shop more than I was able to drive it. The oil light keeps jumping on and off and the dealer is aware of this issue and they stated that the manufacturer is aware of this issue as well. But it seems that they are refusing to rectify the issue with a new engine and just keep patching the problem, that I would have to keep taking back every 1,00 miles for a consumption test. The oil ight was present when they sold me the vehicle but the dealership stated that they had performed an oil change and it needed to be reprogrammed but that did not fix the problem.

THE OIL CONSUMPTION IS OUT OF CONTROL FOR THEIR VEHICLES I'VE HAD MORE OIL CHANGES THAT I'VE EVER DONE ON A VEHICLE I'VE DONE OIL CONSTRUCTION TESTS AND THEY ALWAYS SAY IT'S JUST AT THE 1 QUART THAT THEY ALLOW WHO'S IS BULL I'VE CHECKED MY OIL COLD AND IT'S HARDLY ON THE STICK AND THE OIL LIGHT HAS COME ON NUMEROUS TIMES I'M NO GENUS BUT I DO KNOW IT'S MORE THAN A QUART LOW WHEN YOUR OIL LIGHT COMES ON. AT 1,100 MILES IT WAS 2.5 QUARTS LOW AND I WAS FORCED TO DO ANOTHER OIL CHANGE WHEN I ONLY HAD 1,100 MILES ON THIS ONE. THE FIRST PIC I'VE ATTACHED IS COLD OIL LEVEL AT 1,100 MILES AFTER OIL CHANGE. THE CAR ONLY HAS 53K ON IT AND I WANT TO KNOW HOW MANY TIMES DO WE HAVE TO DO OIL CONSUMPTION TESTS TO GET IT FIXED UNDER THE LIFETIME ENGINE REPLACEMENT AND FORGET ABOUT THE ROADSIDE ASSISTANCE FROM HYUNDAI THEY TOW 20 MILES THAT'S IT AND THE REST IS ON YOU HOW IS THAT FAIR WHEN IT'S NOT YOUR PROBLEM TO BEGIN WITH.

ONE OF MY CONTINENTAL PURE CONTACT TIRES FAILED AT HIGHWAY SPEED AT 4,926 MILES. ALL FOUR TIRES WERE PURCHASED NEW FROM MY DEALER ON 11/25/20. MILEAGE AT THAT TIME WAS 47,314. ON1/21/21 WITH AN ODOMETER READING OF 52,240, ONE TIRE DEVELOPED A LEAK AT THE INTERSECTION OF THE SIDEWALL AND TREAD -- THERE WAS NOTHING STUCK IN THE TIRE INDICATING A PUNCTURE -- YET THERE WAS A HOLE IN THE TIRE. THE TIRE COULD NOT BE FIXED SO I HAD TO BUY A DIFFERENT BRAND TIRE TO REPLACE IT BECAUSE THE TIRE SHOP DID NOT CARRY CONTINENTAL TIRES. WITH THE RECENT RECALL OF MANY TIRES BY CONTINENTAL, I AM CONCERNED THAT MY THREE REMAINING CONTINENTAL TIRES MAY NOT BE DEPENDABLE. I CONTACTED CONTINENTAL DIRECTLY AND WAS TOLD THAT THE PURE CONTACT TIRE IN MY SIZE (215/55SR17) IS NOT INCLUDED IN THE RECALL WHILE OTHER SIZES ARE INCLUDED.
