Started having intermittent misfires on various cylinders, specifically cylinder 3. (Code P0303) This would mainly cause the engine to stall, or idle. No accidents or injuries to report, but having a car stall out at 80 MPH on the freeway is certainly scary as hell. Just frustration and possible damage to other parts of the engine (spark plugs and some wiring). Took vehicle into local auto shop where they reproduced the problem, but informed me of TSB 20-FL-001H, which can only be fixed by a Hyundai dealership due to the ECM reprogramming and the proprietary nature of the tool to perform that. As such I have taken the vehicle to a Hyundai Dealership where, again, they were able to find and diagnose the problem, as well as determine the spark plugs were likely fouled by the known-faulty ignition coil packs. This is the third time in 75,000 miles I've replaced them.

The engine stalled out while driving on the highway. No indicator warning lights came on. The vehicle would not restart. Had to be pushed off the road. Prior to the engine, the tire pressure gauge warning indicator light did not work when tire went flat. I was driving on the interstate 23 back end slid. I pulled off the road and the driver side back tire was completely flat. Put on spare tire.all the lights on dash came on. Went straight to tire garage had 2 tires on back put on. The vehicle is at Tim Short Hyundai dealership in Pikeville Ky. Has been there since 03/11/2022. The engine problem occurred 02/26/22. I had vehicle taken to Carbon Auto Repair shop in Paintsville Ky. The mechanic stated the engine would have to be replaced. I called Hyundai dealership and informed what happened. They scheduled an appointment for inspection. Case # 19459076. Case Manager is Shemroy # is 1-833-462-8722 ext65413. Tim Short Hyundai dealership in Pikeville Ky # is 1-606-437-1300. I have called the dealership several occasions no results or they leave me on the line until it automatically hangs up. They do the Case manager same way.I have only had the vehicle for a 1 year and it is only 4years old total. This is a safety hazard. Multiple vehicles were around me both incidents. I have seen recalls on same make and model as my vehicle. I just don't want this to continue to happen.i would appreciate any help. I uploaded emails to show as well as I have several voicemails saved. I just want the right thing done. Also the paint has peeled off hood roof and now the side panels. The vehicle is at dealership in Pikeville Ky if you would inspected it. Has been there since this occurred.

The car would die while going down the interstate. It would just shut off and you would have to try to safely get off of the road and shut it off and restart it. 60K? miles on the car. We took it to several places to have diagnostic test run and was told it was this sensor then another sensor. Nothing was fixing the problem. Then was told it was the timing. Ended up 2 cam sprockets had to be replaced. Check engine light did come on. This could be a serious hazard if you were not able to get out of the way of other traffic.

Vehicle loses all acceleration when making turns or coasting slowly. Only way to restore acceleration is to put vehicle in park and turn the key into the off position and then restart the car.

For almost 2 years now I have had issues with my vehicle. In the middle of me driving, all the light would come on and sometimes just the engine light and the car would proceed to stop working. This had happened on the highway while I was pregnant and I almost got into a major accident. I have major anxiety because of the situation. Each time I would get the car towed to the dealership where I purchased it. They will have my car for months at a time, notify me when the issue is supposedly resolved and then return car back to me. A week or 2 later, the problem would happen again. I have had to take my car to the shop 5 major times. My safety, my child-€™s safety, and husband-€™s safety have been placed in jeopardy. I am very afraid to even step foot in the car. The problem has never been fixed. My car is currently at the dealership receiving service for the same issue. I am still paying on the car and it hasn-€™t worked for almost 2 years. I-€™ve tried to sell the car back to the dealership but they said there is a negative equity on the car and they aren-€™t willing to pay the difference. When I mention to them all that I have been through with the car, I am told the situation sucks but there is nothing they can do. This car should have been recalled from the beginning and no one ever reported it. I was told by an attorney that after the fourth time, there should have been alternative solutions such as: replacement of the vehicle or compensation. It still makes me feel scared to trust that they will fix the issue because as I have mentioned before, the problem keeps occurring. I have reported to the National BBB and I have 2 cases open with Hyundai Customer Care Center. Hyundai Customer Care Center has yet to respond to me. This issue has effected my ability to go to work because I don-€™t have transportation, my credit, my safety and family-€™s safety and overall wellbeing. I-€™ve tried several times to get this matter resolved. I have all of my receipts.

Often times the rear video backup camera built into the car blanks out when reversing, randomly. Dealership said it-€™s possibly bad wiring but would be expensive to investigate, with me on the hook for paying if they can-€™t locate the issue. After going two years with this issues intermittently occurring, I was able to get a new camera installed under warranty, as a way to ensure the camera itself is the issue. In the end, blanking out condition is still present. I do check my mirrors often but it-€™s not safe for this camera to blank out as often as it does. I-€™m hoping this is an isolated issue but in the case more owners have this concern I-€™d like NHTSA to investigate the matter and if needed, recall affected vehicles. A family member drove my car and was involved in a minor fender bender, with the family member stating that the back up camera camera blanked out a few times in a couple seconds as another vehicle entering their mirrors blinds spots (directly in back of car) came through. If the camera would-€™ve been working properly it-€™s possible my driver wouldn-€™t have stuck the other vehicle.

Driving with no signs or dash lights came on to warning me of any issues. Car started acting like it was stalling out one morning parking it at work. Went to leave work had a very slight almost not noticeable knock sound went I started up. Car was acting like it was running harder then usually. Continued home and my car started seizing up and caused my car to stall completely out while driving on the interstate. I was a mile from home, started my car back up and continued to get somewhere safely and out of danger of the interstate. It stalled out multiple times before reaching my driveway. By then my car seized up and was making a loud knocking sound. I push the car into the garage and check the oil and there was no indication of any oil on my dip stick. Went ahead gave my car an oil change earlier then scheduled. 1.5 quarts of oil only came out and was low almost 4 quarts. No signs of leaking or using oil. No indication dash lights came on to warning me of this issue. With in 3000 mileage of my last oil change, I lost almost 4 quart of oil, no signs or lights and now I have a blown motor in my 5 year old car. This is a huge saftey concern of my, with no indication I had an issue and was stalling out on the interstate/while driving to reach a safe place to look at my car.

37K miles. It started with the engine running roughly, so we replaced a coil ourselves. Seemed to fix the issue but a week later there was an intermittent noise from the engine which sounded like a very small exhaust leak (like pffffft). Occasionally, also intermittent, the engine would make a very loud clanky noise. Car shut off without warning while driving <5 mph. Our mechanic said the code was for the 2nd coil, so we replaced all 4 & spark plugs - just to be safe. Two days later, the same noise issues returned and the car shut off twice while driving in a well-trafficked downtown area (5-10 mph). It did not make noise or stall while idling. We had the car towed to the same mechanic, no codes this time. He replicated the issues by letting the car idle for an hour, then driving it 5-10 miles, it made noises and stalled while going up a very slight incline at <5 mph. He said it sounds like something to do with a loss of oil pressure sending the engine out of time, and the loud noise is the crankshaft. I don't know anything about cars and am just repeating what was told to me. At this time he drained some oil and found metal shavings. He said he could look into the problem but he would have to pull the engine and probably take it apart. He didn't want us to waste money trying to diagnose what seems to be a known issue and a blown engine. Also noted that there are few, if any replacement engines out there. In the past few months, I've had a tire sensor malfunction, the radio/media screen go blank multiple times, and the passenger seatbelt notification goes off even when it's just my cell phone and wallet on the seat. All of the electrical issues self-resolved so I didn't even have time to get too annoyed before this major engine failure. Three weeks from the first noise until this point.

You can not open the rear doors. By the handles inside or out. Sometime they will open if you wiggle the outside handle alot of time. The inside acts like the child safety lock is on. The child safety not on. If an emergency happens the people sitting in the rear can not get out. This started in 2020 on driver passenger first as of today 3/30/2021. The rear passenger will not open at all.

Hyundai avoids taking care of their cars by sending out general statements for techs to "fix" these issues but they never do they say I didnt hear it when brought in mulitple suspension electrical issues my husbands 2019 Hyundai eletrical going out. The engine issue all they did was say didnt do it for me. They need to replace all these known issues it is braking down the whole vehichle for both of us. I believe Hyundai is negligent in worrying about the cost of afull recall so they deny anything.I have videos documents, my car went from red gas to green random clicks deterioration. My hubsands car is the only owner engine shudders randomly they do a fake iinvestigation. Hyundai does not care if you die.

Sluggish, shaky and not acceleration engine light comes on intermediately. Code came up P0301. Changed spark plugs, sensor, inclined the catalytic converter two times. Still the problem persists. Took to Hyundai dealership they said one of four coil packs was going out. The problem was intermittent and the light for the engine was not on. The dealership told me the engine light had to be on to diagnose the problem. Then I found out the agent coil packs had an older style and they wanted me to buy their newer style the part number is 27300 - 2E601. They wanted $700 to put in the newer style coil packs. This issue should be a recall since my car was only 3 years old when the problem started.

We are having the same issue with our 2017 Elantra. Door lock operates just fine but the door won't open from the inside or outside. This is definitely a safety hazard as we have our kids out in the back and need to be able to get them out quickly
