2017 Hyundai Tucson

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.

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.

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.

Issue was first noticed in October 2025 - there are roughly 70k miles on the vehicle. It is a 2017 vehicle, and has regular service (oil, inspection). There was a class action lawsuit for this issue (wylie v hyundai), which was settled prior to the purchase of the vehicle. Vehicle stutters when shifting into and out of first gear. A local mechanic and hyundai both confirmed that it was a transmission defect. The Hyundai dealership initially thought it was an actuator issue, but has since said that it is a faulty gear assembly. it has a DCT (dual clutch transmission). Vehicle suddenly stops and is erratic when driving. Coming out of a stop risks the vehicle shuddering; going through an intersection or turning cross traffic is extremely dangerous as the vehicle could stop momentarily and cause a collision. Vehicle is unable to maintain flow of traffic. The problem appears to be widespread - there are various forums we found where others have this same issue. There were no warnings on the dashboard prior to the issue. When issue appeared a check engine light was displayed.

I purchased a CPO 2017 Hyundai Tucson in June'22 and brought it in for engine stuttering, the car stalling in intersections and was told they couldn't duplicate the problem. I emailed and brought the car in again and still noting was rectified. I've made the oil changes, changed spark plugs, flushed the engine in July and got new oil and everything looked at and in October the engine seized while my husband was driving to work: no oil lights on no engine lights on. Neither Hyundai or the extended warranty will help. My VIN didn't come up in a recall but there's too many problems with other 2017 I would hope they'd look again and help their customers.

I’m submitting this complaint to report what appears to be a serious safety-related engine issue in my 2017 Hyundai Tucson Sport 2WD with the 1.6L DI Turbo engine [T-GDI GAMMA]. I’m aware of NHTSA Recall 21V-727, which covers 2017 Hyundai Tucson models with the 2.0L engine for premature engine bearing wear. The symptoms covered by that recall are nearly identical to the symptoms my vehicle is now showing. My VIN shows no open recalls or service campaigns on Hyundai’s website, but the problems I’m experiencing match those found in many other consumer reports for this same year, make, and model. My vehicle has only 80,000 miles and has had regular maintenance. Examples include loud knocking from the engine that rises and falls with RPM, and metal shavings in the oil. One complaint that reflects the same pattern can be found in NHTSA ID 11680114, which describes engine knocking and metal debris with no warning lights or alerts. My vehicle has also shown no warning indicators. These issues pose a safety risk because they can lead to sudden engine failure while driving. Based on the volume of similar complaints and the overlap with the existing recall, I’m concerned that the defect may affect more than the engines currently covered under 21V-727. I’m requesting that NHTSA review this matter and determine whether Hyundai should extend or expand the recall to include vehicles equipped with the 2017 Hyundai Tucson Sport 2WD 1.6L DI Turbo DOHC 4cyl. Please investigate this issue and hold Hyundai accountable if these defects extend beyond the vehicles already listed.

The 2017 Hyundai Tucson I owned had the engine FAIL (internal bearing failure) rendering the car basically worthless. Hyundai has multiple recalls on this type of engine. My car had 120,000 miles when the engine failed. Hyundai REFUSED to offer ANY assistance on this, fully knowing that these engines have had thousands of problems in Australia and the US. This is a problem they KNOW exist and they are doing nothing!!!! They need to admit the problems and help consumers when this happens instead of trying to WEASEL out of any responsibility. Thanks.
