ELECTRICAL SYSTEM, ENGINE
Was driving on freeway on the way back from visiting family in different state when rpms dropped off and suddenly lost power. Car began shuddering and check engine light started blinking. Put hazards on and somehow managed to pull over to shoulder. No problems with car or anything to indicate anything was wrong before this. Called to have car towed to dealership where they said there was a software problem and it was falsely indicating low oil levels. ECM was reset and software updated for $233 which they said fixed the problem. Said that carbon deposits may have caused the software to misread and that may have been why there was no indication of problems before. Hope so because i have a long drive back.

ENGINE
The Engine Failed. It is currently sitting at the local Hyundai Dealership. As it pertains to my safety, the Engine failed while traveling on a Major Expressway in the morning on my way to work. Upon towing the vehicle to the dealership, it was effectively confirmed to me I am not the only person suffering from this problem. The vehicle has been inspected by the dealership and determined to be an engine failure. No warning, no other symptoms prior to this incident.

SERVICE BRAKES, ENGINE
As soon as I start to press on my brakes the vehicle starts violently pulsating and locks up. Took the dealership they said my rotors and brakes were fine and we're unable to give any reason for this. Without brakes I cannot stop my vehicle and it seems like a faulty ABS but no light on dashboard. The engine consumes nearly 5.2 qts of oil in 1000 miles. Being this is not normal I have no idea I was running out of oil as soon as I was changing it which could have led to my entire engine stalling out and causing me to wreck. It's putting my life as well as other people's on the roads and danger

SERVICE BRAKES, HYDRAULIC
The contact owns a 2018 Hyundai Sonata. The contact stated that while driving at various speeds, the brake pedal would depress to the floorboard with the maintenance message displayed on the instrument panel. The vehicle was taken to a dealer; however, the dealer was unable to determine the cause of the failure. One day while driving the vehicle, there was an abnormal tapping sound coming from the brake pedal while being depressed. The failure persisted while the brake pedal was depressed and the vehicle drove through a concrete post and a fence, causing damages to the post and the fence. The contact stated that the air bags deployed upon impact. Medical attention was not sought at the scene. The contact sustained bruising all over her body. A Police report was filed. The vehicle was driven back to her residence by a neighbor. The dealer and the manufacturer were notified of the failure. The vehicle was not repaired. The failure mileage was approximately 30,000.

ENGINE
This car engine has failed on multiple occasions. About 12 months ago, I observed a great loss of coolant. The car would frequently overheat even when I added coolant. Eventually, I was able to have the engine replaced at the dealership where I purchased the car, but this was right at the end of the vehicle's warranty. Even with a new engine installed, I still lose coolant all the time. It does not appear to leak anywhere, but the reservoir is consistently empty.

ENGINE
There is a rod barring warranty on my car for my engine. My engine has completely faulted. Hyundai has informed me that they are going to take at least 3 months to fix it and will not give me a vehicle for the time they have mine. I took my car to the shop to check it out, a week before it went out and Hyundai was fighting it, so I wasn’t able to get it there until it completely went out after trying to figure it out for a week prior

ELECTRICAL SYSTEM, ENGINE, STEERING
I was driving on freeway and all dashboard warning started to flicker on and off simultaneously then my steering wheel locked in place. I was unable to stop or turn wheel and had to maneuver car until it came to a stop. I had to get it towed home. I spoke with dealership and asked me to tow it to them so they can look at it and gave me a report that mention nothing about what I originally told them it did while I was driving but pointed out everything else that was wrong with it that added up to more than $4,500.00 in repairs. Dealership guy got upset that I asked him to email rather than phone calls and didn’t want to answer anything through email only phone calls he was refusing service and kept pushing us to approve all the other expenses without telling me anything about why the car did what it did. He then told me that it was my fault since car was just passed over 100,000 miles and I should’ve known that was going to happen. Luckily nobody got hurt during this. My wife was pregnant at the time and thank goodness nothing bad happened and dealership guy was so unprofessional and rude and just wanted our money rather than help by giving us any answers.

ENGINE
I own a 2018 Hyundai Sonata SE. The car now has 60,000 miles on it. I first reported to the Hyundai Dealership that my valves are "chattering" with acceleration up to 35 mph. I was advised my engine was low on oil. I completed a oil change and valves are still chattering. I was advised that the engine is dirty and I would have to pay for an engine cleaning at $350.00 After the cleaning the valves stopped chattering for about 1000 miles then the noise came back. I was then told to complete an oil consumption test. Part 1 of the test my car burned 2 quarts in 1000 miles. Part 2 with a cleaning my car burned .5 quarts after a cleaning, so it passed the oil consumption test. I was told by the dealership that after a couple of oil changes or around 6000 miles the car will burn oil again at the rate of over 1 quart per 1000 miles. The also told me that I would have to do the oil consumption test again. The dealership stated that the engine is faulty and and engine replacement is what needs to happen to correct the problem versus this band aid fix. I was also advised if I wanted to speed up the process don't check the oil between oil changes because it will burn 5 quarts of oil before the next oil change. This will cause the engine to lock up. THE ENGINE IS FAULTY IT NEEDS TO BE RECALLED BEFORE SOMEONE GETS KILLED.

ENGINE
My vehicle is unable to accelerate past 65mph. I had it towed to a local repair shop whom ran a diagnostic and they are advising there is a hyundai/kia recall on engine. To my knowledge, I was not advise by Hyundai of any recall when my spouse reached out to Hyundai directly. I was on the highway with family traveling back from Christmas vacation when the incident occurred. There was a crash ahead due to the rain so traffic had slowed down. Once I drove passed the accident and attempted to accelerate the engine light appeared I could no longer accelerate. Very scary when your on a 4 lane highway hours away from home. I was able to pull off to the nearest exit for safety as it rained.

2018 Hyundai Sonata Sport+ with 23K miles that has White Pearl exterior paint. The paint (W8 or WW8) is peeling off from several locations (Hood and Roof). This has been a know issue with this type of paint on Hyundai vehicles but manufacturer is not taking any responsibility that paint or paint job is defective. One can google this issue and thousands of user complaints are there of different forums and messaging boards.
