While driving home from work, my engine all of sudden started making a loud knocking noise sounded like you were going up a roller coaster. The oil light started flickering and then the engine light came on. I honestly didn't know if I was going to make it home due to the noise and the car was shaking while driving. I had to have it towed to the dealership. The dealership confirmed the engine needs replaced. I can't even get a new engine anywhere because no one can order one or find one in stock new. I feel it is a safety issue because the engine could have failed on the highway while driving putting myself and others at risk of an accident or maybe even death.

While driving home from a doctors appointment my engine all of sudden started making a loud knocking noise, the oil light flickered on and off and the check engine light came on. I honestly wasn't sure if I would make it home with the loud noise the engine was making and the car was starting to shake while driving. I did have it towed to the dealership (I have 2 2017 Tucsons both currently at the dealership with blown engines under 60000 miles) and they confirmed the engine needed replaced. I feel this is a safety concern because the engine could have failed while driving putting myself and others at risk of an accident or maybe even death.

As I was driving my 2017 Hyundai Tuscan to work, my vehicle would not accelerate when I pressed the accelerator. The engine would not function properly leaving me in the middle of moving traffic. I was able to pull off the main road to a safe place. My insurance company (Geico) sent an assessor out 7/22/24 who noted a blown engine due to a prematurely worn connecting rod bearing for which there is a noted recall on this particular vehicle model.

Constantly have to get oil changes. Initially when I would be due for another oil change, the mechanic mentions there is no oil. I started to come sooner than the due date and mileage and same issue. Oil is burning quickly. Car is stuttering and jerky on acceleration, but my car is not apart of that recall. The car headlights continues to change on it on and filters through the light settings on it’s on at random times.

My car has been having engine problems causing it to stall while driving. It won’t go past 20miles per hour even if I press on the gas FULLY. This has been happening on and off for a couple of months now. It also burns thru my oil change in less than a week. I took my Hyundai into the dealer multiple times because of the way it drove since 2019 and they always sent me away saying that it was normal. But this car has been a constant stress in my life. Driving it has felt dangerous. Something is definitely WRONG with it and I’m not sure why this recall on the engine now powering up hasn’t hit yet. Death trap of a car.

Hello, I have a serious problem with my Hyundai Tucson 2017 which is excessively burning oil. An oil change has been done on December 26 2023 (125.600) and a service was due 3 month later (3.000 miles) to perform an oil change but when I went for the oil change on March 26, 2024 at Jiffy Lube, they noticed that there was no oil in the engine and no leaks and suspected that the vehicle might burn oil and the performed a full synthetic oil change (service due after 7500 miles) and after 2800 miles on May 17, 2024 when I checked the oil level, I couldn't see any mark on the stick. I brought them the car and they checked if there was any leak then they filled up the engine. I was monitoring and on June 15, 2024 after 780 miles the level was below the minimum level. I bought a Mobil 1 full synthetic motor oil 5W-30 and filled up the engine up to the maximum level mark on the stick. 2 weeks later, on June 28 I noticed that the oil level was close to the minimum level again. I booked an appointment at Hyundai dealership at Gaithersburg, MD and they refused to check the vehicle without a payment. I paid for the diagnosis and 2 day after they ended up saying that the vehicle is burning 1 quart every 2660 miles (which is below what we observed) and they asked me to pay $1235 for a combustion chamber cleaning to which they added it might not work. I am submitting this request for you to solve this safety problem on my car. Thank you

There are two issues. Acceleration failure while driving and excessive oil leaks that require continually adding oil to the engine. Yes, it is available for inspection on request. The acceleration failure is a safety risk and does put others in danger when I cannot accelerate when needed. For example, entering a freeway. The car has stalled and cut out going only 15 mph. This never happened while stopped, just as I was accelerating from a stopped position. I cannot get on roads where the speed limit is above 50 mph because the car will not go over 50 mph. The manufacturer has inspected these problems. Charged me to correct them, and a month later the problems returned. NO warning lights, or anything, at any time.

On [XXX] my 2017 Hyundai Tucson check engine light came on on [XXX] in Atlanta. Just moments afterward my car began to reduce its speed. It was not driving nearly like it should. My exit was approximately 4 miles from when the check engine light came on. At my exit car started vibrating, I did not think I was going to make it through the light. Even though my car was not driving right and the check engine light being on I did not want to stop and be stuck on the side of the road. I was headed to my daughters house about 2 and half miles off the interstate. With my emergency flashers on I made to her subdivision. As I proceeded up the hill it would not go, it started going in reverse. Needless to say I was starting to panic. My son in law was the first car to come, he told me to turn the engine off and restart. That didnt help. So he got in my car and put in Neutral. We were a few yards from their house.

Tucson currently has 98,000 miles on the engine and is burning extreme amounts of oil. Oil consumption issues became known as early as 75,000. Per 1,000 miles of driving, the Hyundai dealership notes the car is losing over 2 quarts of oil. I have been having to return to the dealership every 1,000 miles to be monitored. I have already had to pay replace my catalytic converter, which I believe was a result of the excess rate of oil burn from the engine. I have also had to pay to replace the oil gaskets in the oil pan even though there was no noticeable sign that the engine was leaking oil. I am now being told I am going to need to have an engine head cleaning repair that will take several days. Once that is complete, I will have to undergo continued oil consumption testing to determine the results. They are requesting I produce my service records or Hyundai will not cover the repairs. Almost all of the service on this vehicle was done at the dealership and I was never notified of any issue with oil consumption. A separate mechanic, while performing a quote, did an oil change and noted the car was completely out of oil. This engine is well known for its oil consumption issues and Hyundai does not seem to want to take responsibility for their defective engine.

Engine blew up before oil change was required and car is under 100,000 miles Engine presumably failed on the way home from work, was making a sound. Parked the car, got in the next morning to take it to the repair shop. Check engine light came on during transit. They called and said there was a rod bearing failure and advised that I have it towed to Hyundai for possible warranty work. Car will be repaired in 4-6 weeks. Nalley Hyundai in Lithonia Georgia is not able to provide a loaner car as there are 11 people on the waiting list before me. I have 2 kids and a full-time job. I now have no car for 2 months.

Engine has been burning through oil fast, requiring me to add oil every couple of weeks. 2 difference service places have told me this and also told me to contact Hyundai to file a complaint, as many other 2017 Hyundai Tucsons have recalls out for the same reason. This could cause an engine to fail if oil burns all the way out without my knowledge - safety hazard for me and others on the road. Car also sputters and struggles to accelerate at times, which has been an issue since getting the car in 2020. Please consider recalling to fix said issues.

Have been driving the vehicle for nearly a year but while driving my motor blew exhausting blue all black smoke and then when I turn the car off the car was completely dead when I was getting it towed it could not be told because both of the front wheels had locked and no matter if I put the vehicle in neutral the car will not move come to find out that the bearing ride has shot a hole through the motor block. Took the vehicle to two different Hyundai dealership was told the same thing that no one would take the vehicle or trade it in for an the value for another vehicle that I was stuck with the vehicle and had to pay for the damages which was about 12 Grand also vehicle has been down in my driveway for the last year now cuz Hyundai refused to pay it without $190 diagnostic fee again on top of 12 Grand to replace my motor and the vehicle is not even worth all that money when I don't have much left to pay on it even though I only had the vehicle for only 2 years now but only driven it for only one. Lastly I've also read where there was a recall on these vehicles for the the baron rod and the engine malfunction as well as a new system being put into this these vehicles I was not aware of these recalls because it purchase of this vehicle was right when the recall window had closed and I ended up having a problem now they won't do anything about it can someone please do something about this vehicle.

Had had the vehicle approximately four months (purchased at Irwin Dealership in Laconia, NH) when the vehicle would not start. It was rendered non-functional. It was “repaired” in February 2023. When picked up in Feb after Irwin dealership in Laconia, NH had had it for almost 3 wks, they told me it had carbon buildup. It had only been driven about 4,000 miles since it had been purchased on [XXX], 2022. They changed the oil (oil changes are recommended every 5,000 miles). It died again on [XXX], 2023; again it had been driven less than 4,000 miles and was not yet due for an oil change. It has been there since. They (Irwin) wanted service records, I told them all I had from prior to purchase was the carfax, and that they had performed the only service because I hadn't driven it long enough to have even had a second oil change. When Irwin submitted documents to Hyundai, they indicated the issues with the car were due to neglect and poor maintenance. Hyundai refused to replace the engine citing that I had failed to provide service records. The car remains at the dealership, despite payments being made on a vehicle that can not be used.

I religiously come into a auto repair shop for oil changes. Well before my next scheduled change, my engine started to make thumping noises. I filled up the engine with oil before taking it in to the auto body shop. The shop informed me that the engine needs to be replaced. They also informed me that this seems to be a recurring issue with Hyundai's and that a lot of owners are experiencing high oil needs for their engines. Neither my check oil light or check engine light notified me that there was low oil before the damage occured on my engine. I have filed a report with Hyundai as well and am still waiting to hear back from them.

The engine sustained a crack and oil was leaking out of a cylinder. Initially thought to have been an oil problem since the check oil light would come on. Vehicle was taken to a dealer where they determined it was a bad cylinder. They did not have the correct tools to get into the block so they kept the vehicle for over a month. They returned the vehicle back and shortly after the issue started to happen again. The engine was knocking really loud and cannot accelerate over 40 miles an hour. We took it back to the dealer where they determined that it was a faulty engine and had requested all of the oil change and maintenance records. This vehicle had been taken back to the dealership on multiple occasions for routine maintenance. Talking to the maintenance technicians they could not find any record of us taking the vehicle there mentioning that the dealership had changed hands. We had records from oil changes at one other location but the dealership deemed negligence for the engine failure. This is about a three-year-old case and car was ay 109,00 miles

After owning my vehicle for 4 years, it has started burning oil. Burning about 2 quarts every 14 days. Was directed by dealership to perform oil consumption test every 1000 miles, which is all logged through the dealership and was sent on my way. The problem is now affecting my spark plugs and could packs. After all we're replaced/changed, when plugs are removed, they are covered in oil and are fried! Hyundai has not addressed the issue, but many consumers have this same problem.

I purchased my vehicle on Feb 17th and 2 weeks later the engine shut down on me and wouldnt restart. My mechanic said that i need a new engine.

There's a known leak with oil in the engine, this was brought to the dealers attention and they said it was a known issue however no fixes were avaliable. While driving on the highway without warning I lost accelerator access. The car wouldn't go. The engine started knocking and would not propel forward. It was advised after diagnostics were done that two of my cylinders lost compression and therefore the engine was blown. They said this is a highly known issue with Hyundai Tucson 1.6T engines. I've lost money, time and work behind this ordeal.

We purchased a 2017 Hyundai Tuscon in April 2023 with 79 k miles. Realized after a short time that it was consuming too much oil. Started doing some research and found that this has been a problem for many Hyundai/Kia engines. We were checking the oil often and topping it off as needed plus, oil changes at 3000 miles. There were no check engine lights on and no leaks of fluids on the ground, no loss of power. Fast forward to March 2024. Driving down the interstate on a trip the engine just shuts off. Luckily my daughter was able to make it to the shoulder without getting hit by another car. The vehicle would not restart. I started looking for someone to tow the vehicle a State Trooper stopped to assist her and her passengers. Vehicle was towed. Mechanic charged the battery, checked the terminals, tested the alternator, and the belt. All were good. No idea why it just shut off. After charging battery for an hour, she was able to limp the Tuscon to the nearest dealership. The vehicle started losing power going uphill and regained speed on the flat areas on the way to dealership. The Hyundai dealer diagnosed the issue as leaking valve seal, oil soaked ignition coil causing the misfire which then started to plug up catalytic converter and fouling the spark plugs. I told the service person I will be contacting Hyundai and she said that the diagnosis did not qualify for the engine replacement and the estimate to repair was $5600. While we were there we checked into trading in. We paid $16,000 in April 2023 with 79k miles. March of 2024 Kelly Blue Book says it’s worth only $8300 (93k mileage) and they offered $4000 trade. Loan balance is $14,000. This incident could have caused my daughter and her passengers (one was an infant) to get into a horrific accident on the Interstate with traffic driving 70 mph. Now we are dealing with this economic hardship. My research shows many of the engines of various models of Hyundai and Kia’s are failing. No current recalls!
