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
I've taken the vehicle to several mechanics for engine-idling when turning, going up-hill. I've purchased new plugs, lines, engine cleaners, no-one can figure it out. The oil now has engine shavings even though the oil was recently changed. The car broke down today
The contact owns a 2017 Hyundai Tucson. The contact stated that while depressing the accelerator pedal, the vehicle failed to respond while stopped at a red light. A dealer was contacted. The vehicle was taken to the dealer to be diagnosed; however, the diagnostic result was unknown. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 95,000.
Engine burning oil. Had 2 oil consumption tests and failed both. Had engine combustion chamber cleaned and still burning oil. Hyundai denied new engine
The auto has 112,000 miles and is using oil excessively. A quart with every gas fill up.
excessive OIL CONSUMPTION no leaks its buring oil
Had an oil change on September 29th. The mechanic brought to my attention metal shavings in the oil and advised that I should get rid of the car because it won’t last much longer. It drove fine for a day until the next afternoon I was driving on the highway with my children and the engine started knocking loudly. The car stopped accelerating past 45 mph. I was close to my house fortunately but barely made it as it sounded like the engine would blow. It is now sitting in my driveway still knocking when I start it and don’t feel safe driving it anywhere. There were 0 warning lights. I was not aware of the engine issues these cars had until I did some research and looks like it’s very common. Seeing some people had luck getting replacement engines in the past and many others not. This needs to be addressed and Hyundai needs to be held responsible for the awful oil consumption issue resulting in failing engines. We should not have to provide proof of maintenance when clearly this is an issue regardless.
the federal safety agency Complaint – 2017 Hyundai Tucson Oil Consumption, Engine Defect, and Branded Title I am filing this complaint regarding my 2017 Hyundai Tucson, which suffers from abnormal oil consumption and engine problems. In addition, Hyundai Motor Company internally “branded” the title without disclosure, which voided my eligibility for warranty coverage. These issues create both serious safety risks and consumer protection concerns. 1.Oil Consumption and Engine Issues •This Tucson has had oil consumption problems since the first owner, which I only discovered a year after purchasing the vehicle. •The vehicle burns oil excessively between service intervals, often requiring top-offs after just a few hundred miles. •Critically, the low oil pressure warning light provides no early warning. It only activates once oil levels are already dangerously low, leaving no safe margin to protect the engine. •On multiple occasions, I was unaware the engine oil had dropped to unsafe levels until the vehicle was already at risk of engine damage. •The engine makes knocking/tapping noises, hesitates under acceleration, and has rough idling when oil levels drop — all signs of internal engine damage that could lead to sudden failure while driving. 2.Hyundai’s Branded Title Practice •Roughly one year after purchasing from CarMax, I learned that Hyundai had internally branded the title in their own system due to oil consumption reported by the first owner. •This branding was never disclosed to me or to CarMax, and the official state-issued title and Carfax report both showed “clean.” •Hyundai uses this internal branding to void the extended engine warranty that should have applied to my vehicle. •Despite repeated requests, Hyundai has refused to provide documentation of when or why this branding occurred. 3.Warranty and Safety Concerns •Hyundai has issued Technical Service Bulletins (TSBs) and extended warranties for engine failures caused by piston rings and bearings
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.
Every time I get the oil changed I have to add 2-5 quarts of oil in between changes. I had the catalytic converter replaced 3 years ago and now I have to do it again. I’ve had nothing but issues with this car and oil consumption. I shouldn’t need another catalytic converter again after only a few years. I’m doing my 3rd oil consumption test right now.
Excessive oil consumption, Full synthetic Oil last less than 2000 miles. Transmission takes some time to respond when start driving from a stop. Car shake a bit.
Electric,
Excessive oil consumption! Keep being told that they cannot find an issue
While driving to work on I-26 in the far left lane at approximately 55 mph, my vehicle suddenly and completely shut off without warning. The engine power was lost instantly, forcing the car to come to an abrupt stop in live interstate traffic. I had no prior indication of a problem—no warning lights, no messages, no abnormal performance. It took three attempts to restart the vehicle. When it finally restarted, the engine made a loud knocking noise, and the car could only move at a dangerously slow crawl. I had to cross multiple lanes of high-speed traffic to reach the right shoulder, nearly causing several accidents in the process. Other drivers had to brake hard and swerve to avoid colliding with me. This situation could have easily resulted in a multi-vehicle crash, severe injury, or death. After pulling over and shutting the vehicle off, I checked the oil dipstick and found it completely dry. The engine had failed with no warning whatsoever. The vehicle was later inspected at an independent service center and I was told the engine must be replaced, and that the vehicle is not safe to drive. I am now left without reliable transportation due to this sudden failure. This incident represents an extreme safety hazard. Losing all engine power in the far left lane of an interstate at highway speeds placed my life, and the lives of countless other motorists, in immediate danger. The outcome could easily have been catastrophic. To reiterate: the engine failed without any warning or indication, creating a life-threatening emergency situation. This is a critical safety defect that requires urgent investigation.
I am the original owner of my 2017 Hyundai Tucson. I am a [XXX] retired teacher. I became aware that my 2017 Hyundai Tucson was consuming oil in August 2024. I took my Tucson to Buerkle Hyundai, where it was purchased, and they set my vehicle up for oil consumption testing. Every 1,000-1,100 miles my car's oil level needed to be checked by an authorized Hyundai dealership. This required time and planning. I began working with Luther Hyundai in Burnsville, MN for testing as they are close to my house and requested to take over when I brought my vehicle in for the first check. This engine issue is covered by my 10 year/100,000 mile warranty. My vehicle's oil level was checked as required for the testing. Hyundai considers a vehicle burning 1 quart of oil or less per 1,000 miles to be acceptable. My vehicle consistently consumed oil and when checked May 9, 2025, in 817 miles my car had consumed 1.5 quarts of oil. My vehicle had 88,689 miles on it. My car met the requirements for a new engine, which I'd been told was the warranty repair. Luther Hyundai, Burnsville, MN submitted the repair request. Next I was told I'd have to provide oil change invoices. I brought in oil change invoices for the past four years. Then I was told I'd need to provide invoices dating back to the purchase of the car, 8 years of maintenance records. That seemed extreme but I provided those. Somehow Hyundai Warranty Division is stating my vehicle maintenance is negligent despite having my oil change records that proved otherwise. They have denied warranty repair. Luther Hyundai's service manager wrote emails stating that my vehicle had been well taken care of and serviced. Hyundai Warranty division refused the repair again. When I asked for a written statement of reasoning I was told they could not send one. My vehicle is not safe to drive. I cannot understand how Hyundai can deny a valid warranty claim. I need my Tucson repaired and the warranty honored. I'm unable to upload all files. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFOR
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.
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.
This unresolved issue has created serious safety risks. On two separate occasions, my vehicle lost power while crossing the Leo Frigo Bridge in Green Bay—an extremely dangerous scenario for both my family and other drivers. Most recently, within just ~40 miles of picking up the vehicle from service, the issue recurred. The service department reported finding oil on the ignition coils—symptoms consistent with known and documented warranty concerns such as: Valve cover gasket leaks Spark plug tube seal failure High-pressure fuel pump gasket leaks The vehicle has been brought multiple times to a certified Hyundai dealership for recurring problems including power loss, poor engine performance, and excessive oil consumption. Despite these repeated service visits, the underlying issue has not been properly addressed. I have now been informed that I am responsible for diagnostic charges—even though the vehicle is covered under the TXXM Engine Warranty Extension / Powertrain Limited Warranty due to known oil consumption-related defects.
In April of 2023 while driving I heard a pop noise and my engine started smoking. A connecting rod had broke in half and went through my oil tank. My 2017 Hyundai Tucson had only 54k miles. I was denied warranty and my vehicle was branded maintenance neglect due to lack of proof of oil change but when I sent the dealership I purchased my vehicle from the all my oil change receipts in August 2023 I was still denied and my car is still branded today without explanation.
The turbocharger on my 2017 Hyundai Tucson 1.6T has failed three times within one year. Most recently, the dealership diagnosed the turbo’s wastegate actuator as being completely open, resulting in severe power loss and unsafe driving conditions. The replacement turbo from an authorized parts supplier is still under a 5-year warranty, and the dealership confirmed there were no oil feed or installation issues contributing to this repeated failure. Component/System Failed: Turbocharger (wastegate actuator stuck fully open). The failed turbocharger is available for inspection upon request. Safety Risk: The vehicle experienced severe loss of power while and also the dealer made me aware there is a valve stuck in the turbo itself and if i drive it it could blow the motor up, which made merging and accelerating unsafe and could have resulted in a collision. The lack of engine power when entering traffic or climbing steep grades put both myself and other drivers at risk. Dealer Confirmation: The issue has been confirmed and documented by a Hyundai dealership service center. This is the third turbocharger replacement within one year for the same vehicle, indicating a potential defect or underlying issue. Warning Lamps/Symptoms: The check engine light illuminated (P0299 – Underboost) prior to the failure. I also experienced significant loss of acceleration and increased fuel consumption. These symptoms began days before the dealership confirmed the wastegate actuator failure. Resolution Sought: I am requesting Hyundai Consumer Affairs review this case due to repeated turbo failures, potential underlying defects, and financial burden. I would like to know what Hyundai can do to address the repeated turbocharger failures and associated labor costs.
I own a 2017 Hyundai Tucson with the 1.6L turbocharged engine. My vehicle is experiencing serious and potentially dangerous engine issues, including knocking, loss of power while driving, sudden engine stalling, and low oil pressure. These problems have worsened over time and now occur regularly during normal operation. The vehicle has stalled in traffic on multiple occasions, creating a significant safety hazard for myself and other drivers. I am aware of an existing recall (21V‑727) for 2017 Hyundai Tucson models with the 2.0L engine related to premature engine bearing wear, and the symptoms I’m experiencing appear to be identical — yet my 1.6L turbo model is not included. I strongly believe this issue may also affect the 1.6T engine variant and poses a serious safety risk. I am requesting that the federal safety agency investigate whether the 1.6L turbocharged engine used in this model year should also be subject to recall due to the same type of internal engine failure. I am currently pursuing diagnostics and have contacted Hyundai to request assistance, but the cost of repair and potential danger while driving remain urgent concerns. Please take this report into account as part of your investigation.

The contact owns a 2017 Hyundai Tucson. The contact stated that while attempting to accelerate, the transmission failed. There were no warning lights illuminated. The vehicle was taken to the local dealer, where it was diagnosed and determined that the transmission needed to be replaced. The vehicle was repaired, but the failure reoccurred. The contact stated that while driving approximately 25-30 MPH, the vehicle was making an abnormal rattling and knocking sound that was coming from the engine while accelerating. The transmission was shaking continuously while driving at 10 MPH. The vehicle was taken to the local dealer, where it was diagnosed with camshaft and engine failure and needed a cam finish over an advanced timing system overhaul. The contact was informed that the camshaft, CVT, timing chain and tensioner, front valve cover and valve cover gasket, turbocharger, turbocharger gasket, and turbocharger lines needed to be replaced. The vehicle was not repaired. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 92,000.
The vehicle suffered extreme oil consumption while under the 'famed' 100k mile warranty. Tests were performed at the dealership confirming excessive oil consumption. Hyundai USA refused to service the issue claiming my personal service records did not meet their standards of responsible maintenance. At 108k miles the engine failed while on the interstate in CO. Cylinder 2 had blown and the dealership noted the towed vehicle was low in oil. The engine failure is a direct result of excessive oil consumption, something that hyundai has been aware of and has chosen to fight against owners damaged vehicles, rather than remedy the issue. Hyundai has faced class action suits and settled on these, yet still has not admitted fault. This issue poses a safety hazard for owners who may suffer catastrophic engine failure while driving.
Without any warning, the engine stalled out going through an intersection.
The engine blew. It had to be replaced at my costs because hyduadai does not warrant when a car changes hands. It has 81250 in miles. This is happening to lots of people. It’s a 1.6 L engine. The 2.0 has a recall. But the 1.6 needs to be recalled also. Something needs to be done.
