Misfire, excessive oil consumption, engine knocking, loss of power/acceleration, gas smell, excessive gas consumption

- Dover, DE, USA

Was driving down busy city road when engine suddenly knocked violently and shut off rendering car inoperable as traffic had to go around my disabled vehicle. Inspection revealed low oil, despite filling 4 weeks prior after change and no visible/identifiable leaks. Investigation by mechanic resulted in being told that numerous Hyundai engines like this are having the same problems and need total engine replacements. They said that they "see this at least once a week in these Hyundai's and Kia's". There were no warning lights or anything prior to the event.

I-??ve been having ongoing issues with my 2016 Hyundai Tucson where the car struggles to accelerate, especially after stopping at red lights or pulling out into traffic. Sometimes, when I press the gas pedal, the car either hesitates badly or doesn-??t move at all. A few times it-??s completely stalled while trying to make turns or cross intersections, which has been really scary and dangerous. I did some research and found there was a known recall for this exact problem related to the Transmission Control Module software and the dual-clutch transmission. The symptoms described in the recall match mine perfectly, but when I checked my VIN, my vehicle isn-??t included. I haven-??t taken it to the dealer yet because I-??m worried I-??ll have to pay out of pocket for something that I believe is part of a known manufacturer issue.

Excessive oil consumption

- Leitchfield, KY, USA

My 2016 tuscon has been giving be problems. I went to the dealership awhile back and told them that the oil has been burning having and that there's a perk when I start my car. They did an oil change and told me that I needed to lube the gears up first before running it. I assumed it was because my warranty was ending and because I was a girl, that was a quick go away problem. Well eastward today. I put oil in the engine at least once a week or more. The car is in the shop, and the machanics at pep boys are saying this is a reoccurring problem for this type of car. Also that all 2016 are made with the same engine pretty much so they should all be recalled. They quoted me 10 grand for a used engine. I'm taking it to hyundai, the pep boys told me that it's the same issues as the other recalls

I called the dealership back told them I was bringing my car to them due to the issues it was having. After several weeks the dealership told me my car needed a brand new engine and transmission due to engine rods breaking transmission went out and metal in the oil filter. Not even 6 months later my car is have the exact same issues and my dealership is not want to do anything to fix my car even with having a warranty to cover everything they fixed.

The engine sometimes stalls and does not accelerate in relation to the pressure applied to the gas pedal. This has caused me scenarios where I am waiting to make a left turn and putter into the lane of opposing traffic, instead of accelerating through the turn. Another symptom of the engine is burning engine oil excessively. I am not aware if the issues are related or not.

The exhaust manifold and turbocharger assembly have cracked, causing exhaust gases-?"including carbon monoxide-?"to leak into the cabin. This issue was confirmed by diagnostic testing at Burns Hyundai. The defective component is still installed on the vehicle and has been inspected upon request, costing me over $200 without any suggested reimbursement after I already told them the problem before testing. The cracked exhaust manifold allows carbon monoxide to enter the vehicle-??s interior, posing a serious risk of carbon monoxide poisoning to both the driver and passengers. Additionally, the vehicle-??s engine performance has been negatively affected, which could lead to unexpected failures while driving. Yes. Burns Hyundai conducted diagnostic testing and confirmed the issue, identifying cracks in both the exhaust manifold and turbocharger assembly. Despite this confirmation, Hyundai corporate has refused to cover the repair under warranty. The vehicle has been inspected and diagnosed by a Hyundai dealership service center (Burns Hyundai), and the issue has been reported to Hyundai corporate for review. No inspections have been conducted by law enforcement or insurance representatives at this time. Yes. Prior to the diagnosis, I experienced engine performance issues, including reduced power and inefficiencies, which I reported to Burlington Hyundai in 2021, when the vehicle was still under warranty. At that time, the exact cause was not properly addressed. The problem has since worsened, leading to the recent discovery of the cracked manifold. No specific dashboard warning lights were illuminated for this issue.

Vehicle has shown signs of engine failure for the past two years, all indicating impending need for engine replacement in alignment with engine recall that was issued for vehicle (customer case # [XXX]). Vehicle has been seen for diagnostics related to this problem where both Hyundai in Fredericksburg as well as Springfield Virginia confirmed that the engine was failing. Both dealerships refused to service car (which was under full warranty) because they were prioritizing cars who had already experienced full engine failure. Dealership advised that they could do nothing per the manufacturer until the vehicle experienced full engine failure. They acknowledged that it was a safety risk to myself, passengers & other drivers. The engine has now completely failed, leaving me stranded on [XXX] in the cold winter months & having to pay to have the vehicle towed. It is apparent from my service history report that I took all due diligence in attempting to have Hyundai attend to the engine of this vehicle while under warranty and they flat out refused, citing multiple different reasons. I am requesting a safety inspector come to investigate both the dealerships, the service report history, and the vehicle itself. My legal team is at this point just waiting for me to be offered engine replacement (out of pocket per Hyundai) and once that transaction is complete we are fully prepared to file suit for negligence.

All my doors stick and sometimes I have to fight with my car to even get a door open. Also, when trying to accelerate sometimes my throttle response is slow and i will not move for a few seconds.

On [XXX], I purchased a 2016 Hyundai Tucson Sport, at the Landover-Jaguar South Hills dealer in Canonsburg, PA. On [XXX] the -??check engine-?? light came on. Since I was 2 hours from home, I purchased a code reader to assess the issue. It read -??A P0420 code-??. I researched potential reasons for this code but returned the car to the dealer who performed additional checks and gave the car a -??clean bill of health-??. On [XXX], I was driving home from about 16 miles away and lost power. A slew of dash lights came on, and I was forced to pull over. I smelled something burning. As I stopped, the smoke from the engine became apparent. The car right behind me pulled up and asked if I knew my car was on fire. Another bystander pulled over and extinguished the fire in my engine. This happened on one of the busier roads in the area and if the vehicle exploded it could have been much worse for all of us. This vehicle is currently sitting at Bowser Hyundai in Pittsburgh and is available for inspection. This engine fire and fail is not a maintenance issue but is clearly a result of a manufacture issue.

9/11/24 the 2016 Hyundai Tucson had a knock in the engine, the car was towed to beaverton Hyundai for inspection and I was told that it was Rod Bearing failure that caused engine failure and that this was a known issue for Hyundais Theta II engines and it would be $18k repair. Hyundai just settled a billion dollar class action lawsuit for rod bearing failure where check engine and oil lights failed to illuminate. I asked for a PA to be submitted to Hyundai motors America, as suggested by my usual shop Dick-??s Hillsboro Hyundai(whom didn-??t have availability soon enough). The PA was denied stating -??this is normal wear for a vehicle at 70k miles and it-??s out of warranty.-?? This repair is not a cause my the consumer, but by a manufacturer defect. And I should not be expected to replace the engine at $15k after paying $20k 3 years ago when I bought the car. Hyundai is being negligent.
