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

After having a level 1 drivability test/inspection test done, code P0300, P1111, P301, P302 & P303 came up. Cylinder compression was tested and found cylinder 3 was at 30 PSI. The technician told me that this is a common issue with this make/model and I should take it to the dealer.

When the car is started the airbag light on the dashboard lights up. It will eventually turn off anywhere from 5-30 minutes. I scheduled an appointment with the dealer and was informed , after 10 hours, that they do not have the equipment required to conduct a diagnostic test and they don't know how long it would take to obtain equipment once they requested it. I was told it would cost me a minimum of $850.00 to have test conducted once the equipment arrived since my car was over the 50,000 mile warranty. This cost is just for the diagnostic test. Since this is an ongoing airbag issue on numerous vehicles; I assumed this is a safety issue and would trump the warranty time frame. Please provide any type of assistance on this matter.

It should be stated first that I do regular oil changes in my Hyundai Tucson and was 700 miles from my next oil change. I purchased this vehicle around 2/8/22 (last year). This past weekend, I was driving and when I came to a stop, my oil light came on and the engine shut off. I managed to get my car to an auto store and the dipstick had no oil on it. We added a quart and managed to get the car home. On the way home, my engine was making a knocking sound. My husband took it for an oil change, and the tech noted that there was only about 2 quarts of oil (and that was after I had just added a quart). They completed a full oil change. We immediately made an appointment with Hyundai to have my car looked at and did not drive it until we were driving it to the appointment. On my way to the appointment, my engine began making a very loud knocking sound and would not accelerate properly. Finally, as I was pulling into the Hyundai dealership, my engine completely seized up, the oil and check engine light came on, and the car turned off while I was in the main road. I managed to coast it into the Hyundai parking lot. My Tucson is now at the Hyundai dealership after they had to tow it from the front of their parking lot and I am waiting on hearing back from them what is wrong. I am being told it could take one month before they can tell me anything, so I am without transportation for that long.

I am the sole owner of a 2017 Hyundai Tucson Limited, (AWD) with the 1.6L engine, 7 dual clutch transmission, with 46,000 miles as of today Thursday, February 23, 2023. Currently, I am experiencing problems with the engine/transmission stuttering and vibrating, the gears slipping, and with the inability to accelerate when merging into oncoming traffic. In addition, what frightens me the most is when I am applying the gas when driving and the gears stick causing a brief halt in forward motion then, suddenly progressing forward with a quick burst of speed. On many occasions, I have shared my concerns with the dealership from whom I purchased my vehicle from Hyundai of Chantilly, located at 14848 Stonecroft Centre Court, Chantilly, VA 20151. I have been told that the dual clutch transmissions are trash in so many words and I have been quoted a price of $2000.00 to have the transmission replaced. I am at my wit's end and unsure of my rights and to whom should be held accountable. Therefore, I am writing NHTSA for assistance.

My vehicle is currently experiencing the Oil Consumption Defect that many others have complained about. My car stalled and eventually would only go 30 mph on hills. No low oil lights or indicators were observed before this happened. As well as in December of 2022, Hyundai had to replace my catalytic converter for $3000 which I believe now was the problem of the oil being consumed faster than it should be by the engine. I have been told repeatedly that my oil was almost gone even before an oil change was due. No leaks or oil was ever found outside of the vehicle. The dealership confirmed this issue of a defective rod bearing issue and submitted to Hyundai USA for a free engine under the warranty but are dragging their feet about it and keep requesting additional pictures etc. My safety was put at risk when due to no warning lights or anything, my car just stalled and stopped in the middle of the road. I also was told by an employee at the dealership that my vehicle barely passed Hyundai's bearing test and to "drive my vehicle until it blows up" and then they should be able to cover the engine. I was not willing to put my safety at risk on a highway 300 miles away from my home. So it has sat at the dealership for at least a month now. It was available upon request

Powertrain: Vehicle losses power especially going up inclines or hills. This happened before and I spent over 4500 dollars on repair of a catalytic convertor that failed. This was Late may of 2022. Now the car is back at a Hyundai dealership because the Catalytic Convertor has failed again it is Feb 2023. The car has extreme oil consumption which is one of the causes of catalytic convertor failures. The car in November of 2022 had a loss of power again but this time coils failed. Had all three coils and spark plugs replaced. The certified mechanic shop gave me the spark plugs and it was if they had a black felt on the tip of them. The mechanic said this was a sign of high oil consumption. High oil consumption is also a cause of coils and spark plugs failing prematurely. I have records to show how much oil I have bought and it is about 3 quarts every 1-2 months depending on how much I drive. This is extremely high and a sign of a faulty engine. It puts me in danger of being rear ended in traffic or on an open highway because it losses power. I use my car for work and sometimes that work takes me to small country towns. My work sometimes mean I get back when it is dark or get up when to get to work when it is dark. A car failure on a dark country road is unsafe. Yes a Hyundai dealearship in Decatur and Lubbock TX as well as a certified mechanic in Keller Texas can attest to no warning lights or codes and the car has high oil consumption. Inspected by two different hyundai dealarship service repair locations NO warning lights, no check engine lights, nothing to give notice of a problem about to occur. I have tried to deal with Hyundai but they refuse to accept that the issues are due to a bad manufactured engine. However all the signs point to that is the problem. Lastly the check brake light comes on but mechanics can never find a problem. So they replace the bulb but it just keeps happening. It will come on , stay on for a day , then go off. Just periodic

two things....my back passenger side door just stopped opening...you cannot open from inside nor can you open from outside... won't open at all and now I notice the window 'sticks' I have to put it down and then it will go up slowly. 2nd this car burns through oil and I have seen other complaints regarding this from others online as well. I have to have an extra container of oil to use once every other week and now the muffler is smelling bad no oil can light ever when on but when I bought it used, about 3 weeks later the engine light came on and it started to knock. I went to a Jiffy Lube and they said "you have no oil" there are no spots at work or my driveway! This engine is a joke

I have had my 2017 1.8L eco Hyundai Tucscon for 3 years now and recently it's been giving me signs of problems that are great concerns for safety, as well-known for this models; it only 62091 miles as of the day of this complaint. On Jan 15. 2023, I noticed that each time I start the car, it takes a little bit longer, then you hear a rattle sound and shaking of the engine block, then it start. Or the engine would suddenly slip, followed by a brief rattle sound while driving. I took it in for service to Manly Hyundai in Santa Rosa on Jan 27, 2023, but the mechanics there told me that they could not find where the problems are coming from, and that I would need to wait for an engine light to come on, as any diagnostic at this point maybe unnecessary and costly. Had I known that the 2017 Tucson had so many issues and recalls, or engine defects, specially the slipping or shaking on acceleration from idle, I would never put my money on a commuter like that. I AM STILL WORRIED FOR THE EUGINE NOT TO BLOW UP AS PER PREVIOUS INCIDENTS WITH THIS MODEL. Common issues: The18.0-liter eco 4-cylinder engines, which may have defective rod bearings. The bearings may wear prematurely. This can cause the engine to stall during operation. In extreme cases, a damaged connecting rod can puncture the engine block and cause the engine to leak oil onto hot components, leading to a fire. Please do something.

The car is consuming oil at an excessive rate. Oil needs to be added every 2000 miles. The car will start to run loud and struggle but no leaks can be found and the low oil light is not turning on to warn of low oil. This started about 8 months ago and now I have to frequently add oil every 2000 miles which should not be necessary. There is currently a class action lawsuit pending regarding this issue.

the car was unresponsiveness when pushing the gas pedal, delay when accelerating, shaking, and the gears do not seem to change. this causes problems when trying to merge into traffic, make turns and anytime when acceleration is needed. We took it to the dealership said we needed a Dual Clutch kit however the vin does not have a recall therefore want to charge $2264.00. to fix the problem. it is obviously a manufacture defect. the car has not been inspected by the manufacturer, police, insurance representatives or others.

Engine defective after 70,000 miles driven. Hyundai agreed the engine was defective and agreed to replace engine after it was brought in and diagnosed on December 12th 2022. Vehicle still at dealership awaiting new engine. Dealer stated that engine is on back order as of this date January 23rd 2023, and has no idea when it will be coming in!

My car shudders upon accelerating at low speeds and hesitated to respond to the gas pedal at low speeds. This shows itself when taking left hand turns where the car will stall for a second or two while turning before the car finally pops and the acceleration kicks in. The transmission feels unresponsive. This has been happening since my car had 5k miles on it but is worse now that it has 35k miles on it. The dealer says this is a characteristic of the dual clutch transmission, and that it’s normal, but it feels extremely unsafe and not normal for an automatic transmission.

I have had my 2017 Tuscan a month shy of 2 years. Kept up with oil changes. No oil spots on the cement where I park. Had just had an oil change a few weeks prior in fact. I had loss of power. My car wouldnt accelerate so I took it to Bradford Towing in Haverhill Ma and they looked at it and even put in a camera to see the damage. A bearing in the engine blew a whole through a piston causing an oil leak and misfire. My engine is junk now. Key Hyundai of Salem Nh was contacted by Bradford Towing who confirmed it was a known issue and they had repaired over 80 vehicles in the year prior. My particular VIN hasnt been recalled but it should be. I could have been in an accident or worse. Hyundai wont help me because Im not the original owner and I didnt buy it certified.
