It is my belief that the engine is failing or has something wrong, due to an engine recall. I started having issues with acceleration and took it to a local mechanic who advised it was an engine issue and needed to be taken to the Hyundai dealer asap. As of today, May 27, 2025, it was taken to Autonation Hyundai in Columbia, SC who is alleging that all engine recalls related to my vehicle are not covering any engine issues. I have had this car for quite a while and have never had any issues until now. Multiple diagnostics have been performed.

There is an excessive engine oil consumption on the 1.6L turbo charged motor. Motor oil is completely depleted between recommended oil changes. It is a necessary to add roughly 1qt of oil per 1,000 miles driven, between oil changes, in order to maintain safe oil levels. No signs of leakage, therefore oil is burning at an unsafe rate.

In February of 2025, my oil lamp warning light came on. My husband checked the oil dipstick and noticed that it didn't have any oil on it. There was a visible burn mark as well. I called my local Hyundai dealer to schedule an appointment to see why my car was burning oil like that as it was not due for an oil change. The appointment was made for February 20, 2025. My car at that time had 79,803 miles on it. The Hyundai dealer suggested performing an engine combustion cleaning service, per Hyundai, to see if it would "fix" the problem. They also went ahead and did an oil change. After these services were done, I was told to bring the car back in after 1,000 miles. Hyundai's guidelines are that they allow 1 quart of oil loss per every 1,000 miles. I brought the car back to the Hyundai dealer after 1,000 miles and that was in April of 2025. I was told that my vehicle passed the inspection. The oil level on the dipstick was in the "normal range." After a few weeks, my husband checked the oil level again just to make sure the engine wasn't burning any additional oil since we were not convinced that the engine combustion cleaning service solved the problem. He checked it on May 11, 2025. The dipstick showed that it was below the L. I called the Hyundai dealer once again, and they were able to get me in on Tuesday, May 13th. My mileage was 81,792 on the day I brought it back in. They confirmed that it had burned over 2 quarts of oil in less than 2,000 miles. That is more oil consumption than Hyundai "allows" per their 1 quart of oil for every 1,000 miles rule. The dealer put in a request to Hyundai for a new engine replacement and I was denied due to my vehicle having no warranty.

1)Component that failed: Engine 2)Driving 75 miles on the interstate in traffic and suddenly losing speed was very dangerous. 3)Yes, the issue is still occurring, even worse now as my vehicle shakes just starting the engine. 4) The mechanic has inspected, diagnosed and attempted to repair. However due to the condition of the engine, and the cost of replacing it; fixing may not be an option. 5)The engine light began flashing and then went off; then back to steady on. I purchased this 2017 Hyundai Tucson used just 4 years ago. Everything seemed to be working just fine, I've had regular oil changes. On Saturday, May 10, 2025, as I was driving on the Interstate with my cruise control set, I began to lose power and my speed slowed. I took my car off of cruise control and pushed on the gas pedal to gain speed and my car started to shake and it struggled to pick up speed. My mechanic has changed the spark plugs and performed a BG upper engine induction cleaning; did compression testing and leak down testing. He found that cylinder 4 has no compression. In addition to that, he noticed there was oil on the spark plug. I had my oil changed 3 months ago, and less than 3,000 miles - my engine is burning up the oil to the point where the oil level is extremely low. I have now found out that this is a known issue with this type of vehicle. I'm told it's $10,000 to replace the engine. I have no warranty coverage since I'm not the original owner. I was not aware of the class action lawsuit that was settled last year. I'm extremely upset that Hyundai has not recalled ALL the engines for this make and model of vehicle as it seems EVERYONE has had engine problems.

Purchased this in June of 2024. Ran fine until August 19th 2024 when I was returning to work from my lunch break. I went home for lunch and everything was fine. On the way back, I was pulling out into highway speed traffic and while merging, the engine just stopped. No warning lights or anything. It just stopped running. The vehicles behind me luckily were able to see what happened and get around me without incident. Once I was able to coast back to a safe area, I proceeded to try to restart it with nothing but a click as a response. Tried a few more times with same result. Called roadside assistance and proceeded to check under hood. Found oil stick barely showing any oil when just under 2 months ago it was full, and I had not seen any warning light indicating low oil. Took oil cap off and felt what was inside and found metal shavings in oil. Roadside showed and pretty much confirmed the metal shavings and my worst fear. Still had it taken to a Hyundai dealership where they told me the motor was seized at it would be $13,200 to fix. Asked about the existing class action suit and pretty got told my engine wasn't part of it. After looking at all the complaints here, not seeing how they CANT classify this as a major issue. Still fighting with dealership I purchased from to get something done.

No compression in one of the cylinders, oil blow by, oil consumption approx 1 quart per 1000 miles. Now has developed a serious miss in cylinders 2 and 4 and is undrivable.

Oil consumption issues upon oil change no oil registered at all. It was confirmed no leaking and was advised to contact due to recall on this motor using oil. Also advised to request request a motor replacement due to this vehicle already showing signs of this issue to assure it doesn’t lock up.

I was driving home from the store a short distance from my home. The check engine light came on, the car ran rough, lost power and would not accelerate. I was able to get home. My husband checked the oil; it was 2 quarts low. He previously changed the oil 3000 miles prior. He connected a code reader and it read "DCT 1326". I drove slowly on the berm of the road & able to get home. Had I been on an interstate, my life could have been endangered. Top speed a rough 30-40 mph. After my internet search it appears that oil consumption and engine loss is a common problem. My car has less than 60K miles. No prior history and oil changed every 5K miles.I am very upset about the lack of responsibility on Hyundai's part. This is our 3rd Hyundai and we were loyal customers.

My car became disabled due to engine failure on the highway. My vehicle is no longer drivable. My warning lights did not come on prior to the incident.

Sole owner of 2017 Hyundai Tucson with approx 55,700k miles. Check engine light on and car not accelerating properly. Had same acceleration problem a year ago without engine light, Hyundai dealership stated I needed software update on anti judder gds, update was completed by Hyundai and the issue has reoccurred.

The engine is failing. Our vehicle continues to experience tremendous oil consumption and it's all of a sudden gone into "limp mode" where we lose engine power even after the knock sensor recall update was performed. No check engine lights, no indication of what's happening and it just loses power on the highway as well as city streets. It's a danger to everyone around us and it's a danger for us as we try to drive the vehicle. The dealer / Hyundai had us do 2 oil consumption tests but would not do anything to fix the issue. They informed us they needed to replace the engine after the first oil consumption but then they backed off of that and didn't fix the issue. It’s just gotten worse. We also had a transmission service done and they said the transmission looked fine. We took it in for a diagnostic just after this as the power issue began in "limp mode" where we lose engine power. They are trying to say it needs a new transmission but with the known issues with the Hyundai oil consumption and engine issues where the vehicles go into power loss / limp mode, we’re reporting this issue for our safety and the safety of the community as it’s unsafe to drive this care. We hope you will push Hyundai to do a recall for the engine not just for us but for all Hyundai Owners who are dealing with the same issue.

Engine experienced a catastrophic failure. Driving (normal commute) and clicking noise start coming from the engine. Got louder over a short time, but no dash waring lights came on. Further along the check engine light came, and when it started flashing I pulled over and called for roadside assistance (tow). No other warning lights came on. Engine temp read normal throughout. After the dealer service team reviewed, said the engine block was cracked and metal noted in the oil and filter. I contacted Hyundai USA to see if they would cover engine replacement. After a few days of review and back and forth with the dealer, they declined any claim. Dealer service rep quoted us approx $20k for engine replacement. We opted to sell to salvage company and now need to buy another car. Just over 66,000 miles and complete loss.

Car went into limp mode on the highway because of high oil consumption. Car came to a complete stop.

While driving down the interstate the vehicle would not accelerate and the RPMs were fluctuating. We were luckily near an exit and were able to pull into a gas station. The check engine light came on. Once we parked the engine stalled and we were not able to restart. We had the vehicle towed to a AAA certified mechanic, they stated there was no oil and that the engine needed to be replaced. We did not receive any low oil indicators for the vehicle. We had the vehicle flat bed towed back to our home town where a 2nd mechanic indicated that there was still some oil in the vehicle but that the engine would need to be replaced. The VIN for this car shows no engine recall but this appears to be the same issue that has resulted in Hyundai engine recall with the 2.0 vehicles.

I had my oil changed at a Hyundai dealership at 102,000 miles however even before the next oil change was due my engine had a bearing failure. The dealership could not fix my car for months and that I should find another Hyundai dealership to fix the issue. The next dealership told me that the cost was $14000k to fix and that the engine had oil sludge buildup. My Carfax report is shows consistent and provable oil maintenance every 3K - 4K miles. The engine had been consuming oil which I report to the dealership but sine there was not any check engine light they did not do anything about the consumption problem. I have not yet had the vehicle inspected by independent mechanic or anyone else. no warning lights ever came on that alerted me to low oil.

NHTSA ODI 11651335

A knocking noise from the engine. The dealership is refusing to give us a warranty for the rebuilt of the engine that we will be covering 40% of the cost. Is this possible? For us to spend approximately $7K and not get a warranty on the work done?

NHTSA ODI 11650968

There is metal shards in the oil from the engine. The oil burns up within a week or so. The guy at the oil change place said it was common in these make and model cars and I need a new engine. It can stall or catch fire which can pose a risk to me and/or other cars on the road. I drive around with a [XXX] son it's my daily car and the engine is not good. We are constantly having to put oil in it. Other vehicles from this company have been recalled for the same issue. Please have it inspected and fixed.

Engine failed at 137,000 miles. The vehicle is available for inspection. The engine failed while driving with no warning lights, or indications that anything was wrong. It started with a knock that gradually got worse and worse over the course of 5 miles. Once it shut down it failed to ever restart again. Te vehicle was inspected by a Manufacturer Dealership, they did not give me specific insights as to what caused the engine to fail other than that there was no oil present in the engine at the time of inspection. However I have every oil change receipt, documenting regular, on time oil changes.

NHTSA ODI 11650106

Since reaching approximately 79,000 miles on my vehicle (which I am the original owner of), I have noticed excessive oil consumption. Over the course of 3,000 miles between oil changes, the vehicle consumed about 4 quarts of oil, and the oil lamp came on. Additionally, I consistently experience the smell of burning oil inside the cabin whenever I back in or out of parking spaces/my garage, which poses a health risk. Beyond the health concerns, there are potential consequences, including engine damage, fire risks, reduced performance, and with that, an increased likelihood of accidents. While Hyundai acknowledges that this is a known issue, they have done little to offer a proper solution, merely attempting to keep the consumption within barely acceptable limits. Thank you for taking note of this problem.

My 2017 Hyundai tucson is consumeing oil at a steady rate. Took it to dealership roughly year to do oil consumption test. They said my headgasket, turbo, and pil pan was all leaking. They replaced those parts before starting oil consumption test would be performed. $3,300 later still consuming roughly 1 quart per 500 miles. It faild the oil consumption test and i was advised to do a combustion chamber cleaning next. $700 later and im burning 1 quart roughly every 1k miles. Took it back to them and said thats normal and it is fixed. I'm very concerned considering no car should burn that much oil in between 3k oil changes and only holds 5 quarts of oil. I also have 2 young children and wife that regularly drive the car and it's sluggish when getting on the gas like entering the highway and I'm worried the engine may just go out of nowhere. My local dealership doesn't really care nor does corporate. This is my last ditch effort to get something done. I know I and many, many, many, others are also dealing with this and something needs done soon. Thank you for your time.
