6 Mar 2023 check engine light comes on. Took to my mechanic (they were closest to me) to put on machine to find out what the problem was; they state that it was the knock sensor and said to take it to the dealership and also let them know that it was down one quart of oil since the last oil change Jan 2023). Dealership took possession of vehicle on 8 March 23. Didn't begin repairs until 5 Apr. Then they state there was still noise from engine and found scoring on the cylinder walls and may be why it's consuming oil. Then they wanted oil change records. Finally, after providing records, "Hyundai approved replacement of engine". Legal battle ensued because they were charging for parts (lifters) that were no longer on my vehicle. Ended up having to pay for the full invoice after bullying and terroristic tactics only to have the check engine light come on again (picked up the evening of 15 Aug 23, CEL came on at 06:00 on 18 Aug 23). Eminent engine failure, limp mode and/or fire potential make me afraid to keep my vehicle but financially, I must keep it a while longer.

Rear passenger door will not open without manually adjusting the internal door handle components with a screwdriver (or similar tool). This poses a huge safety risk, trapping a passenger in the vehicle. I am in the process of having the door repaired, but this issue has been recalled on other models and the cost of repair should not be on the consumer, since it is a known defect.

Was driving down the road when it started making a metallic noises then all of a sudden the car sputtered, shot flames and smoke out from underneath the car and metal debris went flying. I had to tow my car to the dealership where they still have it. They said there is a hole in the engine block where a rod was thrown. After this incident we looked more into the problem to find that other Hyundaia have had the same issue. No check engine light came on, the car didn't over heat or anything it was random.

My Hyundai Tuscon has started to burn oil in 5/22 and I brought the car to the dealer (Pugi Hyundai in Downers Grove, IL) and the dealer at the time was directed by Hyundai that the vehicle needed to wait to do an oil consumption test. In 2-23 the vehicle was taken to Wilkens Hyundai and they preformed work on it. The vehicle still continued to burn oil. Hyundai stated I could not pull the dipstick and check oil. in 6-23, the I made a rapid stop in the vehicle and the oil pressure light briefly displayed and the engine started lightly sputtering at highway speeds causing a brief loss of power. At the same time, there was a brief period of blue smoke emitting from the exhaust causing visibility issues for me and other drivers. This event put me and other drivers at risk, The vehicle has been inspected by the dealer multiple times and it has not been determined the cause of failure and I am unable to check my oil during the oil consumption tests, putting me and other drivers at risk due to a potential stalled engine or seized engine due to loss of oil pressure.

Vehicle caught fire damaging wiring harness. engine has hesitation, AC system was damaged by fire. recall shows electrical system/engine and brakes in recall. Hyandai refused to replace citing missed oil changes. oil was changed regularly but not always at the dealer. These particular problems are exactly what the recall was for, problem is design and manufacturing the oil change issue has no effect. I want these fixed as soon as soon as possible

Excess Oil Consumption, Gear slipping, Dual Clutch, Fly Wheel, Oil found in the Turbo inlet, Clutch dust found in the transmission, Encouraged to just keep adding oil and drive the vehicle. Encouraged to drive the car when there was assumed to have contaminated transmission fluid. Encouraged to keep extra oil in my car since it was consuming oil rapidly but was still considered with in specification from Hyundai. Encouraged to add oil and drive the car after it stalled and quit working. This is a known defect with Hyundai's. Some even catch fire and also stall at high speeds while being driven.

I am not a mechanic but when I drive my vehicle, I feel like it doesn't have enough amps to move it along like it's missing something. I have pressed on the accelerator and heard a "winding noise" like the little engine that could but wants to. This is a horrible car!!! I have only had this vehicle for a month and it's a nightmare to drive. It sometimes does not accelerate, and the take-off is unbearable gives me the impression I will be rear ended one day. It even jerks and sputters, even the "rpm" feature shows high acceleration at inopportune times. I had a diagnostic performed and was told the plugs and ignition coils needed to be changed so I did that to the tune of $400 for the parts, and now not even a week later I am being told I need to change them again. How can this situation be rectified? I don't have another $400 every month in addition to the payment and insurance to replace those things every month. I want to know if you all have a fix for this to prevent all this unnecessary money from being spent. I am aware that a tune up is necessary but every month. Please tell me how this can be fixed thank you.

There is a problem with the dual clutch transmission on this 2017 Hyundai Tucson. There was a class action suit filed 2016 for transmission defects including the hesitation and shuddering issue and also grinding noises. I purchased this vehicle in 2020 with only 6600 (yes, hundred) miles not knowing of any problem or issues. 2023 in Tucson AZ when the weather started getting very warm end May, June I started noticing a bit of hesitation, sometimes like a grinding noise. This was not happening all of the time but from the reviews it happens when it gets warm. The shaking or shuddering as they call it and hesitation is very prominent and continuous now. When I had my car in for oil change in Tucson at the Hyundai dealer the service manager even drove it and said it was the dual clutch transmission. I asked about replacing the transmission then and he said that I did not have a warranty. That was another issue as I was told by Hyundai corporate before buying the vehicle that the 100,000 warranty would transfer to me. I found out in July it did not. I opened a case with Hyundai service who contacted Eastside Hyundai and I even got a call from the svc mngr who drove the vehicle. He said that Hyundai would not end up covering it all even if they said they would, they may have to have car for awhile and I would need a rental, and anything else negative about the situation. That manager never called back so caseworker called another dealer numerous times and said that they could check out my car in November. This vehicle is getting worse and possibly a danger. Hyndai take is November, take it or leave it and thats all they can do. This can cause long term damage to the engine and other parts. I need some help with this if possible before resulting in litigation. Are you able to advise on this issue and if you have even heard about. No accident has occured with this vehicle YET. I have approximately 21,000 mile on my vehicle now.

Vehicle caught fire while driving despite recall fixes. Vehicle was serviced by a dealership a week prior to the incident. While driving the ABS and other lights on the dash starting flashing, the steering was started to go out then smoke started coming into the car vents inside the vehicle. While I was not injured my only saving grace was that I was already in the left lane during rush hour traffic. The vehicle was inspected by both insurance as well as a Hyundai USA representative, the Hyundai representative would not state the cause of the incident citing "proprietary information". The vehicle is a total loss. There was not any crash involved to ignite a fire.

Loud knocking coming from engine.

NHTSA ODI 11538543

On July 22nd, the duel clutch malfunctioned & caused the vehicle gear shift to no longer engage. The car does not move in Drive or Reverse. It can only be pushed in Neutral or towed. This occurred while I was driving home on the highway with no warning lights or prior symptoms indicating a potential issue. The vehicle has not yet been seen by Hyundai but they did say that since my VIN was not registered to the existing recall, there is not much they can do & any repairs would be out of pocket. It has been seen by our family mechanic, PepBoys & has currently been sitting at AAMCO with no solution as of today since August 2nd. Geico said since this is a mechanical issue & not an accident, they cannot assist. Carmax Customer Relations (where I purchased the Vehicle on March 12th, 2023) has been informed but so far offered no solutions. I am told they cannot offer much assistance due to the 90-day warranty being surpassed, extended warranty not being purchased & the current milage on the car. A case with Hyundai Customer Relations has also been opened as of today, August 15th & they are escalating the issue to their legal department as we are considering taking legal action at this point.

Excessive Oil Consumption

NHTSA ODI 11538328

Excessive oil consumption, vehicle hesitate and sputters when attempting to enter into traffic. Spark plugs expire early. We've been dealing with this worsening issue for 40k miles. My wife no longer feels safe driving this car. Dealership could not recreate the problem. They likely know what the problem is.

Oil drain plug fell out while driving down the highway and oil drained from engine causing internal engine damage. Low oil light came on and engine stalled within seconds. No warnings or lights were on before this happened. Stuck on the side of road for an hour with my family. Had it towed to Hyundai. Tech said drain plug was laying in the skid plate. No oil left in engine. They replaced filter and filled with oil the idled the car for some time and test drove. Tech said no power and there is internal engine damage. Service rep told me to call oil change facility where serviced last. They said cause was human error so warranty will not cover repairs. My car is still sitting at the dealership. Valvoline express care last serviced 22 days and 1336 miles before the drain plug fell out. Valvoline directed me to NHTSA investigation for this issue.

The engine started burning oil and making clanking noises. I took it to the dealership where they told me that the vehicle will need a full engine replacement. The vehicle has 76k miles and well maintained. Just out of warranty. It's unacceptable for a modern engine to have these sort of problems. And I'm not the only one. I know a lot of people have been having the same issues with this same type of vehicle.

NHTSA ODI 11536116

Starting in early 2023 my engine started consuming oil. My car only has 60,000 miles on it. It's ridiculous to do an engine consumption test because this is a known issue with a class action lawsuit having already been filed. There are numerous complaints out there about this issue and yet an engine recall has not been done. Hyundai needs forced to replace these engine NOW before someone is killed with one seizing in traffic. I just did an oil change in February. I clearly don't drive my vehicle often at all. I noticed an issue at acceleration all the sudden it would bog down and not take off. Thinking I needed to change the air filter I did just that and then the check engine light came on. I made it to an O'Reilly auto parts store with a code P0011. I checked my oil to find NOTHING on the dipstick. Second time this year this has happened.
