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 NHTSA 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 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.

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.

The contact owns a 2017 Hyundai Tucson. The contact stated while driving at an undisclosed speed, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended. The contact became aware of an abnormal knocking sound. No warning lights were illuminated. The contact stated while driving uphill, the vehicle stalled and lost motive power. The vehicle was taken to the dealer; however, the failure was not duplicated. The dealer requested an oil consumption test. The oil consumption test was performed and indicated that the engine was consuming an excessive amount of engine oil. The contact stated there was no warning light to indicate that the oil pressure was low. The contact stated that the oil was six quarts low. The failure was persistent. The contact stated that there were several failures reported to the dealer. The contact stated that while driving uphill, the vehicle stalled and lost motive power. The vehicle was towed to an independent mechanic. In addition, the contact stated that the abnormal knocking and ticking sound was persistent. In addition, the contact stated that the engine was six quarts of engine oil low every two weeks. The vehicle was taken back to the dealer.

The engine in my 2017 Hyundai Tucson Limited failed at approximately 111,000 miles. The vehicle began to run roughly, misfiring and losing power with no warning lights or prior indication of an issue. Within days, the vehicle became undriveable and had to be towed to a dealership. The dealership diagnosed the issue as a cylinder misfire due to internal engine damage caused by excessive oil consumption. They confirmed the only solution was a full engine replacement. I was told this issue is not currently covered by recall, despite its similarity to known engine defects Hyundai has recalled in other vehicles. This failure posed a serious safety risk. The vehicle stalled and lost power while driving, making it dangerous to accelerate or keep pace with traffic. Fortunately, the failure did not cause an accident in my case, but it easily could have in different circumstances. There were no dashboard warning lights, oil pressure warnings, or check engine indicators before the symptoms began. The oil level had not been excessively low, and the car had been well maintained. I have opened a case with the manufacturer, but assistance was denied due to mileage and ownership history. This appears to be part of a broader pattern of engine failure in similar Hyundai models. I am reporting this in hopes it contributes to further investigation and potential recall expansion.

My 2017 Hyundai Tucson 1.6 liter is experiencing severe engine issues that closely mirror those subject to recent class action lawsuits. The engine exhibits excessive oil consumption. I have experienced a sudden loss of power on roadways in traffic as well as on the highway. This issue happened just today. Unfortunately due to a loss of smell, I have been unable to smell if there has been burning oil, however in between my last two oil changes (I only bought the car in October) I had to go it to get it refilled or refill it myself. I use full synthetic oil as well. I brought it into a reputable mechanic and I have been told if I continue to drive the vehicle the excessive oil consumption will lead to premature engine failure, potentially causing a dangerous stall or accident, putting myself and other motorists or pedestrians at risk. The mechanic received codes P0420, P0300, P0302, P0303, and P0304. They were able to conclude oil consumption based on the low amount of oil in the vehicle, the spark plugs being oil fouled, the misfiring on three cylinders, and the P0420 code. I called customer service, the Hyundai dealership in Clive, IA, and the contact for the class action lawsuit and litigation II. I was informed my VIN number was not part of the current recalls or class action, however the symptoms are identical to those widely reported. In the litigation my make and model are mentioned, Hyundai Tucson 2017, however it is listed as the 2.0 liter engine. My engine is mentioned, the 1.6 liter, in at least one other vehicle. I believe this vehicle was only excluded by a lack of representation at the time of the litigations. From my call with the dealership, and in research I am not the only one experiencing this problem. While I was lucky enough not to have been harmed, this has the potential to cause great harm. As someone who works for a DOT, safety first is in everything I do. I believed this necessary to report for the safety of all those involved.

My engine was recalled and they inspected it and said it was fine in 2023. Fast forward to June 2025, My engine failed. I took it back to the dealership and they tested it and said "it was not bad enough to be fixed under the recall." Before I took it the dealership the check engine light was on, reduced power when accelerating, knocking noise from the engine that increases when the rpms increase, and the oil pressure light is flashing. Upon taking it to the dealership the check engine light has been turned off, but all the other issues still remain. All of these issues were components to the recall. I have called Customer Care and they assured me that it would be fixed at no cost under the recall, and then I requested a different dealership due to terrible customer service at the prior dealership. Customer Care then contacted prior dealership, and went based on the incorrect findings of the dealership, they are refusing to fix my engine that is under recall. Because they inspected it in 2023 they marked the recall campaign as closed.

We purchased this car brand new in 2017 for my late mother.... It had 12000 Miles on it and started shaking intensely last year. We took it into Tuttle click Hyundai multiple times and they said it was fine.... Charged us several thousand and it continued to shake so we took it back multiple times. They have taken tons of our money and the car shakes as it drives.... Yesterday we found out that there was a major recall on this engine and we were never notified.

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 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.

On [July 4, 2025], while driving, my vehicle experienced a sudden loss of power followed by smoke and flames coming from the engine compartment. The fire required emergency response and caused significant damage to the vehicle. Thankfully, no one was injured, but the incident posed a serious risk to my safety and others on the road. I had not received any prior warning signs such as engine knocking or warning lights. The fire appears to be directly related to the known defect outlined in Recall 209. I am requesting that NHTSA investigate this incident and ensure Hyundai is held accountable for the full scope of this defect, including fire risk. I am also seeking assistance in ensuring Hyundai provides appropriate compensation or resolution for the damages caused.

Vehicle Make/Model/Year: Hyundai Tucson 2017 NHTSA: Recall Number 21V727000 Description of Problem: My vehicle is affected by a known safety recall related to the engine (likely recall campaign P1326 or similar, affecting Hyundai engines). I contacted the authorized Hyundai dealership to schedule the recall service. However, the dealership is requiring me to pay out-of-pocket for parts and/or tests -?" specifically, they mentioned charging for testing engine gaskets/joints -?" before confirming whether they will replace the engine under the recall. The recall notice clearly states that diagnosis, testing, and any necessary engine replacement should be done at no cost to the consumer. The dealership-??s request for payment appears to be in violation of federal recall laws. I am being forced to delay this safety repair because I cannot afford these unexpected charges, which I believe are not allowed under NHTSA recall policies. This compromises my safety and could affect many other consumers in the same situation. Please investigate this dealership-??s handling of the recall. I am requesting that Hyundai be held accountable for ensuring proper and legal recall service.
