What 983 owners told NHTSA about the 2017 Hyundai Tucson Fuel Cell

2022-1-09 Left the house to run errands and noticed the car seemed sluggish when I stepped on the gas to accelerate. I'd actually felt like this may have been happening for some time but it is a "Sport" and it always felt a little funky when you accelerrated. It was blistery cold so my initial thought was I left too quickly and the vehicle maybe needed time to warm up. It felt like the engine didn't either seem to be shifting to a higher gear, or getting enough power to accelerate which was very concerning as this happened as I pulled out onto a busier road, yet couldn't accelerate. I made it to my first stop but called my husband to express concern something seems off with the vehicle. I told him I would likely skip my errands and come home for him to take a look. After my stop, I started the Tucson up to head home - and now the check engine light came on (solid)! Apparently flashing check engine is more serious? I was able to make the drive home to unload groceries but the whole ride home I couldn't accelerate properly so it was a scary drive home, I drove slowly on backroads and used my flashers to get home safely. We immediately called the Hyundai dealer near us which closed. Called four times the next am as we needed whatever was going on fixed quickly. Once the vehicle was at the dealer, we learned it had complete transmission failure. Thankfully it appears this is under warranty. It is STILL at the dealer as it needed to get an inspector to come out to confirm it was transmission failure (which has now been confirmed 10 days later).

Engine started to misfire on PA turnpike, causing loss of power. Engine light came on. This was on a stretch of road with downhill s-curves at night. Car has been using a quart of oil every 500 or so miles. Turbo disintegrated at 100,000 miles, this current incident happened at 120.000 miles. I believe they are related. So far, Hyundai say that there is no compression in at least one cylinder and they have to disassemble engine to determine extent of problem. Engine codes stated multiple misfires in cylinders 2 and 4.

EXCESSIVE OIL CONSUMPTION causing engine failures. Excessive engine oil consumption, will also shorten the service life of, oxygen sensors and catalytic converters, spark plugs and much more. ALL which I have had to replace since buying vehicle used in May 2021. This vehicle is not on the vehicle engine replacement recall campaign and I am not sure why. THERE IS OBVIOUSLY A MAJOR ENGINE MANUFACTURING PROBLEM. Hyundai should be responsible for manufacturing problems and they also should do what it takes to fix the problem. MY REQUEST: for Hyundai to reimburse me the money I have spent fixing, repairing and money spent on oil to operate this vehicle. AS all the information shows, this is a manufacturing issue with the engine and NO VEHICLE should consume/burn this much oil. It has been proven that EXCESSIVE OIL CONSUMPTION causes engine and parts failures. THERE are no leaks detected either by the dealership or repair shops. Frequently having an oil change doesn’t change anything. I had an oil change (yes I have all receipts of repairs) less than a month ago and I have already had to put in 2 quarts of oil.

My vehicle was broken into on Nov. 17, 2022 and thieves attempted to take the vehicle after smashing the back passenger window and gaining access. The vehicle alarmed once they either attempted to either open the drivers side door or start the vehicle. Police were called and completed a report on scene. On Nov. 23, a thief returned and gained access to the vehicle by shattering the glass on the back driver side of the vehicle before getting inside and driving off in the vehicle. I reported the vehicle stolen to police and the vehicle was recovered later that evening. On Nov. 25 I went to the tow yard where the car was taken to retrieve my belongings and observe and record the damage. The entire steering column was stripped down and damaged which is how the thief was able to start it. There are highly circulated videos on social media platforms showing criminals or would be criminals how to do this. It is now also known that they are targeting specifically Kias and Hyundais due to Hyundai manufacturing cars between 2016-2020 without immobilizers. My make and model being one of them and therefore making me a target. Not only that but the cars are being taken and used for joy rides, as mine was, or used in crimes. My car sustained additional damage as it was crashed into another vehicle during the thieves joyride before they ultimately jumped out of the car and abandoned it in an intersection. I was targeted, my livelihood put in jeopardy and if the car is fixable I will still be in harm's way once the repairs are completed. Hyundai needs to be held accountable as there is no way I would have purchased this vehicle knowing that the car was missing a major safety and anti-theft component. Further, why were they allowed to manufacture and sell these cars without such an important component??

I was driving to work after dropping my son off and I took a right turn onto a street and my car slowed down and the check engine light came on, flashing. I continued to drive to work as I was one minute away and needed to get off the street asap. (where I turned had no room for pulling over). I parked my car. I had a prenatal appointment to go to, so I started my car. No check engine light when started until I got on the on ramp to the mass pike, my car went from 50 to 35 in a matter of minutes. I went into the breakdown lane until the next exit which was only a mile or so. I pulled into a gas station and called my husband to come get me as I still had an appointment to go to. After my appointment we retuned to my car and had it towed to the dealership as it is not safe to drive while pregnant. They told me it may be an engine issue and they will try to expedite my car. What annoys me is that this happened before and they claimed it was because I was over my oil change mileage and deemed it my fault and made me pay almost 300 for them to fix it. Yet I feel as if that just bought my engine time before it actually failed. This also happened with my 2015 Sonata Sport back in like 2018/2019 before someone rear ended me and totaled me. But what is my luck that this happens with 2 of my Hyundai. It is very frustrating.

I have a Hyundai Tuscon 2017 ECO and I am experiencing the same engine symptoms as others involved in recalls. The car is only 5 years old but I have noticed that it has stuttery starts from stops and when just trying to accelerate. The engine would often jerk while driving. The vehicle is at 111,000 miles and now the engine is knocking and has very weak take off to the point it’s not drivable. This poor take off has almost caused me to get hit multiple times. There is no telling when it would happen. After the knocking started I spoke with a mechanic who said that the engines burn oil quickly which I have never been told in the past five years. If this was the cause I would expect the manufacturer to inform the owners that is an issue. No one in the past 5 years worth of oil changes (including many at the dealership) mentioned this until the engine needs replaced. I would expect a engine to last longer then 5 years and 111,000 miles before giving out.

The components that are malfunctioning are the gas nozzle entrance, and the dual clutch transmission. It’s available for inspection, and is being inspected currently at a dealership. My safety’s been put at risk to combustion when filling gas, resulting in risks of fire and/or explosion. The dual clutch affects my, and others, safety with major hesitation, jerking, and risk of stalling at any given time. The problem with sparking at the gas nozzle entrance has been reproduced and recorded by the dealership server al times. The dual clutch was diagnosed as faulty and replaced twice, both within a two and a half year span (from which I was told it will continually happened and need to be replaced down the road). The issues have been inspected by dealership, KenGraff Hyundai Surprise, Arizona 85388. There were absolutely no warning lamps, messages, and/or symptoms of the problems.

October 7, 2022 my wife with my 7yrs old granddaughter was driving on the highway. She stayed in the middle of 3 lines. At some point the engine lost power shaking badly and quickly slowed down to 30 miles/hr in 70 miles/hr speed limit zone with semi trucks moving in quickly and honking. Thankfully she managed to stop safety on the side of the highway. Later diagnostic showed multiple misfire on all cylinders and opening the engine showed cracked cylinder. I, backed by 2 independent mechanics opinion, think the crack existed long time before the incident. I reported to the car dealer service excessive oil consumption (1qt every 600 miles) only to be told it’s normal. Then the Hyundai Corporation denied 100 k warranty repair blaming without any proof, poor maintenance
