LATCHES/LOCKS/LINKAGES:TRUNK LID:LATCH
I was headed to pick up the kids to take them to practice, but when they went to open the trunk to put their sports gear in it, it was "stuck". It had worked the previous night so I was very confused. After several tries, we finally got it to open and shut. We then went to the park to kill time and I went to open the trunk again, it wouldn't open. We tried everything, and after 30 minutes, it decided to open. However, it then would not shut. We couldn't leave the park with it open so had to have help come and strap it closed. The kids missed their practices and I was alone in a parking lot with two kids until help could arrive.

ENGINE, POWER TRAIN, UNKNOWN OR OTHER
In September 2022, we noticed a noise coming from under the car hood. Sounded like a thump as we accelerated. We took it to the Hyundai’s service department and was told that they couldn’t hear anything or find a problem. They changed my oil. We continued to hear a noise but thought it wasn’t a concern. In February, a fairly new tire went flat and we returned to the Hyundai service department. I received a call later and was told that they could hear a noise and they checked, and my oil was extremely low. They topped it off and told me to return in a thousand miles to see if it was still burning oil. If it was burning significant oil at that point, they would seal it and begin the Hyundai oil consumption test. At about 600 miles, I could smell a strong plastic burning odor and we checked the dip stick and the oil was barely detectable. We called Hyundai and was told there was nothing they could do and we have to go the full thousand miles to determine if we qualify for the test. We are concerned are engine is going to stall, burn up or catch fire in our garage. They told us, we couldn’t get are car in to be looked at until the end of March. After doing some research, I am aware that there is a current class action lawsuit against Hyundai for this issue.

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

ENGINE
Check engine light came on, difficulty accelerating from a dead stop or going up an incline. I had it at to 2 different locations to be placed on a computer, code P0010 for intake (A) camshaft position actuator circuit. I had that replaced only to drive the car for a week and a half for the check engine light to come back on when accelerating up an incline and have the car almost come to a stop. New code, P0302 misfire #2 cylinder. All four spark plugs were replaced, a compression test was performed to confirm low compression on cylinder #2. Car is drivable, however check engine light will continue to come on because of the low compression but was told to baby the car as the engine should probably be replaced sooner than later and I don't have thousands of dollars for this fix. And last be not least, excessive oil usage.

ENGINE
Engine suddenly shutdown while driving in the middle of the road. Luckily, I was not on the highway. Had it towed to my mechanic and he told me that there was a class action lawsuit on these engines and that they were known to fail after 100,000 miles. I never got any notification about this problem. I am checking with the Hyundai dealership about replacing the engine.

ENGINE, UNKNOWN OR OTHER
I just drove up a small hill and then I had to accelerate to get onto the on-ramp to match the speeds of highway traffic. The engine shut off. no lights from the cluster gauge illuminated. had to really use my leg muscles to step on the brakes really hard to avoid a front collision. had to really use the muscles in my arms and hands to steer the steering wheel hard too. it felt like the loss of brakes and steering capabilities turned off and were really hard to use when the engine turned off for no apparent reason.
