2017 Hyundai Tucson Engine

The contact owns a 2017 Hyundai Tucson. The contact stated that while driving at an undisclosed speed, the check engine warning light illuminated. The vehicle was taken to two independent mechanics, and DTC: P1326; was retrieved. The vehicle was not repaired. The contact was advised not to drive the vehicle and to have the vehicle towed to the dealer. The vehicle was towed to the dealer, and the contact was informed that a diagnostic fee would be charged. The contact stated that the TSB: 21-01-023H was performed in February 2025. The dealer was informed that the same failure had occurred. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 92,200.

Engine is burning oil causing the catalytic converter to clog and fail. Hyundai dealership told me after I had the car towed to them for repair on 12/30/2025 that the catalytic converter had already been replaced before in March 2024. I had purchased the car from another dealership March 2025 and the catalytic converter replacement was not on the car fax. I was also I formed by the Hyandai dealership that my car has an extended warranty of 10 year/150,000 miles on the engine due to the known oil consumption issue. My car has 131,000 miles. I was told Hyandai will make it very difficult for engine replacement since I’m a second owner. There needs to be a recall immediately.

The contact owns a 2017 Hyundai Tucson. The contact stated that while driving at an undisclosed speed, an abnormal pop sound could be heard coming from the engine. The oil warning light was illuminated. The contact was about to merge to the side of the road when the contact noticed a glow on the underside of the vehicle. The contact then pulled into a parking lot, smoke was emitting from under the hood, and entered the vehicle through the A/C vents, and noticed the flames under the hood. The contact stated that the heater was turned on, and the contact immediately turned off the heater. The contact opened the hood and used a fire extinguisher to extinguish the flames. The fire department was called to check the vehicle to make sure the fire was extinguished. The fire department used a thermo reader to make sure that there was no more risk of a fire. The vehicle was towed to the residence. The contact towed the vehicle to the dealer, where it was diagnosed that the engine had failed. The contact was informed that the vehicle had an open recall pending: NHTSA Campaign Number: 21V727000 (ENGINE). The dealer informed the contact that since the recall was not performed, the engine had failed. The contact stated that he was the second owner and that the vehicle was purchased in 2022. The contact was unaware of the recall at the time of purchase. The dealer refused to complete the recall repairs. The vehicle was not repaired. Most recently, the contact was informed that the connecting rod failed and punctured the bottom end of the engine. The vehicle remained at the dealer unrepaired. The manufacturer was made aware of the failure and denied the recall repairs. The failure mileage was approximately 107,000.

Purchased used via Carvana in Sept 2025, check engine light came on while driving it home indicating a pre-existing mechanical defect. We submitted the claim through Silver Rock (Carvana's warranty company) and brought to their approved mechanic. The recommended the following repairs, several that were denied by Carvana/SilverRock: spark plugs, alternator, serpentine belt, fuel injection service, electrical ignition coil. A month later check engine light illuminated again and through further diagnostics the mechanic found that 2 of the faulty spark plugs were an incorrect model/fit for our vehicle and reported that information which resulted in replacement being approved (a month after initial request). Fast forward to January 2026 we experienced the widely reported knocking noise while driving coming from the engine and had it towed. The damage is a thrown rod and damaged bearing, which is consistent with the current oil consumption litigation, requiring engine replacement. Our 2017 Tucson 1.6 L turbocharge is not included in the recall. Furthermore, Carfax report shows last oil change reported was 2023. Carvana confirms an oil change is part of their 150 point inspection before a sale, however unable to provide me with documentation and failed to report a record of the work to Carfax. There are many instances of negligence on Carvana's part from failure to provide record of maintenance, which is also failure to adhere to their standard policy, and declining recommended service directly from their approved mechanic, knowing that this vehicle could be impacted by the well known defects through Hyundai. We are requesting assistance with engine replacement meeting safety standards and ensuring consumer protection.

The contact owns a 2017 Hyundai Tucson. The contact stated that while driving at various speeds or accelerating from idle, there was a knocking sound coming from the engine. While accelerating from idle, the vehicle failed to exceed 30 MPH, requiring that the driver slowly accelerate and gradually increase the speed. No warning lights were illuminated. The vehicle was taken to a certified mechanic who diagnosed the vehicle with transmission failure. The mechanic replaced the brakes and tires. The vehicle was then taken to the dealer, who diagnosed failures with the muffler assembly and catalytic converter related to the failure to accelerate. The failure persisted, and the vehicle was returned to the dealer, who confirmed the noises coming from the engine while the accelerator pedal was depressed, with a burning odor, and oil issues. After five visits to the dealer, an oil leak from the drain plug was determined. The drain plug and oil pan were replaced a year and six months later. The vehicle continued to fail to accelerate properly, making it difficult to drive uphill. The vehicle was taken to another dealer, Niagara Hyundai of Grand Island (1910 Alvin Rd, Grand Island, NY 14072), who confirmed that the vehicle was not safe to drive. The catalytic converter was replaced again but the failure persisted, and there was no engine oil in the vehicle. While driving 65 MPH, the vehicle started shaking. The contact pulled over to the side of the road and waited approximately 10–15 minutes before continuing to drive at 50 MPH. The contact inspected the vehicle and noticed that the engine was hot. The vehicle was towed back to the second dealer, who performed an oil consumption test requiring the contact to drive 1,000 miles. The test determined the engine oil level was extremely low. The dealer suggested a chamber cleaning, but the request was still pending. The manufacturer was made aware of the failure and opened a case. The failure mileage was approximately 63,000.

MY engine check engine light and than a warning light came on saying not to drive it and i took it to be repaired at a shop and a hyndai dealer and they told me my engine needed to be replaced even though i always serviced my car. It has 103,000 miles on it. It is the same problem as the other person that reported this problem. The other models were recalled but not this one. Im sure by now you know there is a problem with this engine too. It should be replaced by the company!!

The contact owns a 2017 Hyundai Tucson. The contact stated that while driving approximately 70 MPH, the vehicle lost power, decelerated, and the check engine warning light started flashing on and off. The vehicle was parked on the left shoulder of the highway and later driven to the right shoulder with the assistance of a State Trooper. The vehicle was later towed to the local dealer, who diagnosed that the engine had failed and needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure, but no assistance was offered. The contact was informed that the vehicle was previously serviced under NHTSA Campaign Number: 21V727000 (ENGINE). The contact stated that the vehicle had experienced the failure listed in the recall. The failure mileage was 66,000.

Engine lost power suddenly on the highway. Vehicle entered limp mode and became limited to 45MPH and reduced acceleration.

am submitting a safety complaint regarding my Hyundai vehicle due to repeated engine power loss (limp mode), excessive oil loss, and a denied engine recall replacement. I initially brought my vehicle to the dealership after experiencing engine power loss/limp mode, engine oil loss, and illuminated check engine warning lights. The dealership confirmed that my vehicle was covered under an engine recall and stated that the recall procedure was completed. As part of this process, the dealership performed an engine combustion-related service and charged me approximately $1,600. After this repair, I drove the vehicle for approximately 1,000 miles. When I returned the vehicle to the dealership, the vehicle entered limp mode on the same day it was brought in, and the check engine light was illuminated again. The dealership advised me that the vehicle had lost an excessive amount of engine oil during the 1,000-mile period. Due to the continued engine issues and oil loss, the dealership requested a full engine replacement under the recall. However, Hyundai denied the engine recall replacement request. The vehicle’s repeated loss of power, excessive oil consumption, and limp mode create a serious safety concern, especially while driving at normal road speeds. I am concerned that the recall remedy was ineffective and that the denial of an engine replacement places drivers at risk. I am requesting that NHTSA review this matter for potential safety defects and improper handling of a known engine recall issue.

I purchased this car from drive time, and when told about a possible recall on the engine i asked about it. We were told that the issue had been resolved. Not even 10 minutes after driving it off the lot the engine started misfiring, we had done a test drive prior to purchasing this vehicle and nothing had popped up on the dash about any problems. We have been unable to get it looked at. I was not sure if a report should have been filed until now. i am unable to produce photos at this time

Loud knocking in the engine that increases or decreases with the rpm. Metal shavings found in the oil. Appears to be same issues described as active recall for 2017 Tucson’s, but no recall for this vin. No alerts were or have been triggered within the car. This has not been brought to a dealership out of fear of seizing the engine.

My car has been consuming large amounts of oil and as a result has had two catalytic converters replaced. Twice now we have been disabled on the highway due to aggressively poor engine performance.

Component/system: Engine / powertrain – excessive engine oil consumption. The original engine is still in the vehicle and is available for inspection upon request. On 11/7/2025 my dealer (Ourisman Hyundai in [XXX] ) added 2 quarts of oil at 90,999 miles after the dipstick showed a very low level. After that visit, we drove approximately 713 miles (mostly highway, including a college visit trip), and the oil level again dropped close to the same low point on the dipstick. On 11/22/2025 at 2:10 PM, with mileage at 91,815, the dipstick again showed a significantly low oil level. I am concerned that this abnormal oil consumption could lead to sudden engine failure or loss of power while driving at highway speeds, putting my family and others on the road at risk. This vehicle is used regularly for my daughter’s college visits and everyday transportation. The dealer has acknowledged the concern, previously performed a combustion chamber cleaning on 8/11/2025 (Invoice #XXX), and has submitted a request to Hyundai for assistance. However, a formal oil consumption test or official diagnosis has NOT yet been completed, so the exact cause is UNKNOWN. The vehicle has been inspected by the dealer, and Hyundai Motor America has opened a case, but there has been no final decision or repair yet. There have been no warning lamps or messages on the dashboard; the only symptom has been repeated, excessive oil loss between visits, verified by multiple dipstick and odometer photos.

My 2017 Hyundai Tucson is experiencing severe oil consumption, which appears to be related to a known manufacturing defect affecting Hyundai engines from this period. My vehicle is burning through oil rapidly between normal oil change intervals, and it has begun showing signs of low oil levels despite no external leaks. This creates a serious safety concern because the engine can fail without warning. The dealership has acknowledged that excessive oil consumption is a known issue for this engine but refuses to provide assistance because I do not have “enough oil change documentation” over the years. However, this issue is not caused by lack of maintenance — it is a widespread internal defect that Hyundai has issued multiple technical service bulletins for. My car has been maintained, and oil changes were performed at regular intervals, even if I do not have complete paperwork. The rapid oil burning is ongoing and dangerous. I am concerned about the engine seizing, stalling, or failing while driving, which could lead to a crash. This is a safety hazard that should be investigated and included with other Hyundai engine cases. Requested Action: I am asking NHTSA to investigate this oil consumption defect affecting the 2017 Hyundai Tucson and require Hyundai to provide a remedy, including repair or engine replacement, regardless of perfect maintenance documentation, since this problem stems from a manufacturing flaw.

vehicle is burning through oil.

I have a 2017 Hyundai Tucson with approximately 120,000 miles. The vehicle had issues with oil consumption and jerking when put into drive. I took the vehicle to the dealership to be checked and was told it was fine. I recently was driving at 70 mph when the engine light came on and lost power. I had it towed to a mechanic that checked and cylinder #3 had lost compression. After finding this out I did an internet research and found that this is a common issue with this motor and vehicle. My vin is not included in the recall but Hyundai has replaced other engines in “goodwill” when the vin number was not included. One search shows that it usually happens from 120,000 to 150,000 miles. After the mechanic looked at the vehicle, Hyundai instructed me to take it to a dealership. After another tow to the dealership they said it was only the spark plugs but upon futher investigation they found that the cylinder was damaged with scoring to engine. The cost for a used engine with 54,000 miles is 10,000 and is more than the value of the car and the remaining loan amount of 10,000. So far we are out approximately 300.00 in towing fees. The dealership has not yet billed us for the checking they have done. We have contacted Hyundai with a response of no help to replace the engine even though the company has helped others in our situation. We haven’t replaced the motor due to the amount owed, cost of used motor vs the value of the vehicle. The safety of the vehicle is very questionable due to the high incidence of this happening and there could have been catastrophic consequences if I would not have been able to pull off the road.

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.

1- I purchased a 2017 Hyundai from CarMax in Edison, NJ 2- Within one month the car broke down, choking and not being able to go highway speeds 3- Brought it to Goodyear, (CarMax’s repair provider for their warranty). They replaced the ignition coils, engine modules-coils, performed a GDI/PFI 2-step fuel system cleaning, (known as Top Engine Cleaning. They replaced the spark plugs and the engine air and cabin filters. The engine was clogged with carbon deposits. 4- 7 Months later the same thing happened and the same work was done by Pep Boys. 5- Two to three weeks later it happened again. The work was guaranteed so they “fixed” it again. They also said the engine was low by 2 1/2 quarts and there was a problem with that engine, I should check with Hyundai. 6- I was told by Hyundai’s corporate office to go to one of their dealerships and get an Oil Consumption Test, which consist of an oil change and then have it tested after 1,000 miles. I will get 2 - 4 test before a determination is made. 7- The car failed the first test, having consumed 2 1/2 quarts of oil within a 1,000 miles. 8- I was told I had to get a Top Engine Cleaning, (the 3rd one within 13 months), before I can continue the test. 9- I get the engine cleaned for, $1,434.11 then resumed testing. 10- The car failed again and I was told by Corporate that they are dropping my claim because the car has too many miles and is too old! From the very beginning they knew the year of the car and the mileage. I am being defrauded and I’m now stuck with paying a $485.90 car note along with a $269 a month insurance bill for a car that was no good from the very beginning! Please,I need your help to hold Hyundai responsible for their promise to give me a new engine after following the steps they required of me, and/or holding CarMax responsible for selling me a car with an engine that is no good. This has cost me thousands of dollars on top of what I’m paying for the car!

Excessive oil consumption leading to catastrophic engine failure

The auto has 112,000 miles and is using oil excessively. A quart with every gas fill up.

Engine burning oil. Had 2 oil consumption tests and failed both. Had engine combustion chamber cleaned and still burning oil. Hyundai denied new engine

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

Excessive oil consumption

My 2017 Hyundai Tucson has been chonking out and having acceleration problems. I thought it was because of AC running. When I took it in for inspection my mechanic stated it was misfiring. I am meticulous about routine maintenance (I.e. tire rotation and/or replacement, oil change, inspection, etc), as well as whatever if any repairs are needed. I immediately reached out to my local Hyundai dealer but they never responded. It should be corrected by Hyundai and a recall issued. After researching the issue I see I’m not the only one with a problem. The 1.6 L engine should have been recalled because apparently the same turbo engine in the GDI model was. I have all my maintenance records to support my claim. Come Hyundai!!! I thought you stood behind your vehicles?????

My engine has been burning oil. The engine light has been on for just over the past year because an O2 sensor in the catalytic converter needs replacing, however, this is unrelated to the issue. The oil light started flickering earlier this year (approx 8 months ago) but would never stay on. I called my mechanic and they recommended I check the oil. Sure enough it needed oil. Since then I have had to continuously add oil in between oil changes, however, the oil light rarely comes on or flickers to indicate this need, I just need to check. The engine has been making a ticking sound and that gets louder or worse I have noticed as the engine burns the oil. I have read up on other 2017 Hyundai Tucsons having the same engine failures and that some are covered under recall but mine does not seem to be. My mechanic has informed me that the engine needs to be rebuilt in order to fix the problem. I am worried about the car dying on me or causing an accident because of the failing engine. Yes, this problem has been confirmed by my mechanic.
