The hybrid system failure. Chrck engine light is flashing. Abs system failure. Battery failure. Car can't go over 45mph, lost a job because of the issues. I'm afraid the car is going to blow up or catch fire. I'm afraid to drive it. The acceleration is barely there. It's like the car doesn't even wanna go. It sucks through gas like no other.

I purchased the vehicle in December and the same weak it began leaking oil the window won’t roll down and the car shuts down by itself. It caused me to have an accident and the dealership has repaired it 14 times with the same issue. They are forcing me to drive an unsafe vehicle I need to report this vehicle as unsafe

I took my car to a shop due to my car having a loud knocking noise coming from the engine bay and lack of acceleration as well as the oil light flickering on and off and once the mechanic inspected my vehicle he said metal particles were being deposited into my oil due to internal engine parts. After picking my car up all the lights on the dash cut on and the car completely had no steering, no brakes, no power but the radio still worked. I barely could turn the steering wheel nor could stop the vehicle due to this and thankfully could coast into an upgrade leveled hill and stop the car. Car would barely recrank or hold power nor would go above 40 mph. Only drove 5 miles to get the car back home safely. Drove back around 3:00 a.m. so there wouldn't be much traffic out in case of something like this happening. Could've been catastrophic!

The Abs brakes and traction control go in and out and affects the brakes while driving, I know there been reports of fire but for some reason my car is not in the recall, same thing with the air bags lights come on showing faulty air bags and on scanner tools but not recalled even though Hyundai knows about these issues. Now for engine I went to have my engine looked at 2 times for oil consumption and all they did was a combustion chamber cleaning twice which both failed in less the 8100 miles so when I took it back for another oil consumption test for the 3rd time today, the engine light came on, it started knocking, lost power and riding rough. Well, they did an engine scanner test and suspect faulty rings allowing oil into the combustion chamber and fouling my new sparks plugs that was installed less then 10000 miles ago, now they tell me I need a new engine and refuse to replace it for free even though they said they fixed the problem before with the engine cleaning now the same part is the problem and now, I am without a car to drive! They tell me I can lose power while driving which could lead to a car accident.

On or about August 13 2022, I notice the oil engine light come for a second, then it went off. After parking vehicle at my home and letting the engine cool off a bit and oil to settle, I checked dipstick only to find out that is was showing DRY no oils whatsoever, I then bought 1 qt of oil and added it to engine still dip stick showed dry and not a drop of oil on it. With still 3,000 miles to go before my next oil change, I decided to take it to PepBoys for a new oil change. After one week dip stick was showing oil on the low side and this time the metal on the stick showed whiteish, like it had been over heated. after this decided to take it to dealership GOSH HYUNDAI In Hemet 92545. I was told it would take 2 days to do some checks and get it ready for an oil consumption test. That is drive vehicle 1000 miles then take it in for another inspection (hopefully 1 day) then getting it back, drive another 1000 miles, then take back for another inspection. Being this my only Vehicle at this time, I am not sure why it takes so long to figure this out. OH did I mention Hyundai headquarters (I'm guessing) has to approve the oil consumption test, otherwise I am out a vehicle and have to pay for repairs. Not too mention the brake fluid reservoir is doing the exact same thing, fluid is being completely replaced every month to month and a half, by replace I mean adding a full reservoir worth of fluid because it seems to be evaporating. I am on the the third time adding fluid to this vehicle after GOSH Hyundai worked on my brakes (10000 miles a go). But this one I will have to pay 165 dollars for them to check it out. Nothing was said about me paying for engine oil issue check, plus they had me sign a affidavit to make sure I was the only owner on vehicle witch I am...So now the waiting game begins and to wait until someone makes a decision about fixing this issues?!!
