2017 Hyundai Tucson

The contact owns a 2017 Hyundai Tucson. The contact stated that while driving at an undisclosed speed, an abnormal knocking sound was heard coming from under the hood, and the RPMs independently increased. The "Check Engine Oil" warning light illuminated. The contact managed to pull over to the shoulder of the road, and the vehicle was towed to a local Midas shop, where it was diagnosed with total engine failure.The vehicle was towed to a local dealer, who discovered metal shavings in the engine oil pan during diagnosis. The vehicle was not repaired due to the high cost. Upon further investigation, the contact associated the failure with an unknown NHTSA Campaign number. The manufacturer was made aware of the failure. The failure mileage was approximately 62,000.

#1. This vehicle uses a lot of oil !!! It burns through it like crazy I have to check the oil every other day. #2. When I come to a stop while driving and give it gas to take off IT WONT GO !!!!! It hesitates and when it does go it LUNGES FORWARD!! This is a huge manufacturer problem not a buyer problem. The engine is junk.! 3. I’ve called numerous places to get help. This car needs to be recalled. This is a huge safety violation. It doesn’t wanna go when you give it gas and when it does, it lunges forward that can cause a huge accident on the highways. This car was made in China. It is junk. I’ve called to get help with this issue and no one wants to help. Nobody returns my calls and I’ll Hyundai wants to do is it even more money out of me when this isn’t my fault the car is junk. For safety concerns I would like someone to call me at [XXX]. This car needs to be recalled and my daughter has one. It’s doing the same thing except hers is a lot worse. Hers is further advance where it’s actually stalling in the middle of the road while driving huge safety violation.

I am filing a safety complaint regarding my Hyundai vehicle after experiencing a sudden engine failure that appears consistent with known rod bearing and engine defects affecting certain Hyundai engines. While driving, my vehicle began making a knocking noise and shortly thereafter suffered catastrophic engine failure. The engine lost power and became inoperable, requiring the vehicle to be towed. This failure occurred without any prior indication that the engine was about to fail. My concern is that this type of engine failure creates a significant safety hazard because it can occur unexpectedly while driving, potentially causing a loss of power in traffic and increasing the risk of a crash. The dealership inspected the vehicle and engine but did not report excessive sludge buildup. I have provided available maintenance records showing that oil changes were performed during my ownership. Despite this, there appears to be disagreement regarding the cause of the failure. I am aware of reports involving rod bearing and engine failures in similar Hyundai vehicles and believe NHTSA should investigate whether this failure is related to a broader manufacturing or design defect. The cost of replacing the engine is substantial, and consumers may be placed at risk if these failures occur while vehicles are being operated on public roads. I am requesting that NHTSA review this issue and determine whether additional investigation, recalls, or other corrective actions are warranted.

While traveling on the highway the car began to lose speed rapidly until coming to a complete stop, no warning lights were present prior.

The contact owns a 2017 Hyundai Tucson. The contact stated that while driving at undisclosed speeds, the vehicle was consuming an excessive amount of engine oil. The contact stated that oil was frequently added to the engine. The vehicle became inoperable. The vehicle was towed to a dealer, where it was diagnosed and determined that the catalytic converter needed to be replaced. The catalytic converter was replaced; however, the failure persisted. The vehicle was returned to the dealer for inspection, and the catalytic converter was replaced a second time. The vehicle was repaired; however, the failure persisted. No additional repairs were performed. The manufacturer was notified of the failure. The approximate failure mileage was 86,000.

Catastrophic engine failures AT 57k miles while driving, resulted in engine replacment under recall warranty. Timing chain replacement done at 93K miles. Second Engine failure while driving at 107K. Hyundai refuses to fix the engine.

2017 Hyundai Tucson | VIN: [XXX] | Mileage: 75,000 I have owned this vehicle for approximately five years and have experienced severe excessive oil consumption for the past two to three years. The issue was first discovered when the vehicle entered protective mode due to critically low oil levels despite a routine oil change having been performed only a few months prior. I am currently required to add approximately one quart of oil every month to maintain safe operating levels. I visited an authorized Hyundai dealership to have an oil consumption test performed. The dealership informed me that if the test confirmed excessive consumption, I would be required to pay out of pocket for an engine replacement. I declined, as Hyundai Motor America has publicly acknowledged this exact defect in the 2017 Tucson through NHTSA Recall 21V727000, multiple Technical Service Bulletins, and a class action settlement covering 2014-2021 Tucson vehicles with the Nu 2.0-liter GDI engine. My VIN was found ineligible on the class action settlement website despite the acknowledged defect. Hyundai has admitted this engine suffers from premature bearing wear, excessive oil consumption, and risk of engine failure and fire. I am requesting NHTSA investigate why my VIN falls outside current recall coverage despite presenting identical symptoms to affected vehicles.

Catalytic converter has now failed twice with only 105,000 miles

The engine (connecting rod bearings in the 2.0L Nu GDI engine) failed. The vehicle entered limp mode with DTC P1326, then died on the road and the engine seized completely (will not turn by hand when attempted; only clicks on starter). It is currently at First Hyundai dealer in [XXX], under Repair Order #XXXand available for inspection. The vehicle suddenly lost power and died while driving on the road. This created a significant risk of an accident or being stranded in traffic. I was on a busy highway and almost got hit twice. There is also a known fire risk associated with this exact defect (oil leaking onto hot engine components), as stated in Recall 209 (NHTSA 21V727). The vehicle was towed to First Hyundai. They have documented the no-start/seized condition on Repair Order #XXX. A prior independent scanner reading showed P1326 before the code was cleared. The dealer has not performed the full diagnostic inspection (scheduled around June 11). Hyundai Corporate (Claim #XXX) has been notified but has not responded after multiple escalation emails. The vehicle first went into limp mode ("Engine Protection Mode") with DTC P1326 on the scanner. Shortly after, the engine died completely and would not restart. This occurred after Recall 209 (bearing/KSDS campaign) was completed on XXX. Additional Details: This is a known issue with premature connecting rod bearing wear. The dealer is refusing to provide a loaner/rental upon drop-off, which contradicts TSB 22-01-023H (Dealer Best Practices for P1326 vehicles). The vehicle has been inoperable since 6/4 ..with no resolution. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Left rear passenger door latch failure to open either from inside or outside. This is a mechanical failure of the cables operating the latch. A passenger could not easily exit the vehicle in an emergency situation, also there is no way short of breaking the glass to easily access or if necessary extricate the passenger in an emergency situation. As evidenced from online searches and forums this failure is all too common and has been addressed with a narrow set of vehicles with an extended warranty applied to this failure. This is an issue of safety. There needs to be a recall to upgrade affected vehicles and their door mechanisms.

I am submitting a complaint regarding a 2017 Hyundai Tucson Ultimate AWD equipped with the 1.6L Turbo Gamma GDI engine. My vehicle currently has approximately 127,000 miles and has experienced sudden engine knocking consistent with rod bearing failure and/or catastrophic internal engine damage. The vehicle has been properly maintained, including regular oil changes. However, the engine began consuming excessive oil without warning. Upon inspection by an independent repair facility, the engine was found to have extremely low oil levels despite being within the normal oil change interval. After refilling the oil, the engine continued making severe knocking noises, and the repair facility advised that the engine is likely non-repairable and requires replacement. This failure appears materially similar to the rod bearing and engine failure issues already widely documented in Hyundai/Kia engine defect investigations and class action settlements involving related Gamma and GDI engine platforms. I have learned that Hyundai extended warranties for certain vehicles with similar engine defects up to 15 years/150,000 miles; however, my specific Tucson trim/engine configuration does not appear included despite experiencing the same type of failure. This vehicle has also previously required major drivetrain repairs under warranty, including two transmission replacements and turbocharger replacement. My concern is both financial and safety-related. A sudden engine failure or seizure while driving could create a serious roadway hazard and risk of loss of power in traffic. Additionally, Hyundai dealerships have advised that replacement engines for this vehicle are no longer readily available. I believe Hyundai should further investigate whether the 2017 Tucson 1.6T Gamma GDI engine should be included in existing engine defect warranty extensions and/or recalls.

The vehicle has experienced life-threatening safety defects during operation; shaking, hesitation, and stalling in high-speed traffic. The vehicle unexpectedly stalled/lost power while driving, putting myself and others in direct risk of collision. The Hyundai dealership claimed it needed an Actuator Gasket replacement, Throttle Body replacement, and ECM/TCM update. The vehicle had NO warning lights until after it stalled, then warning lights illuminated briefly. The Hyundai dealership claimed repairs were "completed" 5/8/26; within 72 hours of "completion" the vehicle's symptoms reappeared. The Hyundai Executive Case Manager has made NO efforts to resolve this LIFE-THREATENING SAFETY issue. This has put myself and children in danger and is legally unsafe to drive.

My 2017 Hyundai Tucson is experiencing dangerous, sudden engine stalling, which are symptoms directly matching Service Campaign T1B. These critical safety issues surfaced following a total engine replacement in June 2025. Despite the vehicle being within the 12-month/12,000 mile workmanship warranty, the dealership is refusing to honor this coverage or offer goodwill assistance. My claim is based on a documented pattern of physical and technical negligence: - Failure to Update Software: The dealership failed to perform the mandatory ECM/TCM software integration (Campaign T1B) during engine swap, which is required to prevent the exact stalling I am now experiencing. - Dismissal of Warning Lights (Code P0456): One day after the engine replacement was “completed,” I returned to the dealership because the Check Engine Light illuminated with Code P0456. This was dismissed by the service provider without a proper diagnostic resolution, despite being a direct indicator of improper vacuum line reconnection during the engine installation. - Mechanical Negligence (Coolant Leak): Post-engine swap, the vehicle developed a coolant leak, which was a direct result of improper reassembly. Additional proof of the lack of due diligence during the repair. The lack of follow-through, combined with the dismissal of a life-safety defect and poor physical workmanship, suggests a total failure in the case management process. I am urgently requesting assistance to resolve this hazardous situation.

The panoramic sunroof glass suddenly shattered while the vehicle was being driven on the interstate, with no visible impact, object strike, or prior damage observed. The component involved is the sunroof glass panel, and it has already been removed and replaced through insurance repairs, so it is not available for inspection (however, pictures are available upon request). The incident created a loud, explosion-like sound and resulted in glass fragments falling into the interior of the vehicle, including onto the driver and the front-seat passenger, causing minor injuries. This also created a significant safety risk due to driver distraction, panic, and the potential for more serious injury while the vehicle was in motion at highway speeds. The issue has not been reproduced or independently duplicated by a dealer or service center; however, it was inspected and documented by the insurance company and repair facility during the claims and repair process, which confirmed that full glass replacement was necessary. The vehicle or component has been inspected by insurance representatives and a repair shop, but it has not been inspected by the manufacturer or law enforcement. There were no warning lamps, dashboard messages, or any prior symptoms indicating a problem before the failure occurred, and the sunroof appeared to fail suddenly and without any advance indication while the vehicle was in motion.

The vehicle has a difficult time turning over when cranking, the RPMs are sticking and the car periodically shuts off at red lights. Several warning lights pop up when it won't crank and then other warnings when the car just completely shuts off at red lights. I drive the interstate in [XXX] daily for work, so with the engine stalling my safety is at risk every time I drive it. Likewise when it won't crank, my safety is at risk. I had two Hyundai recalls updated in my car in 2022, Hyundai Recall 209 which was a connecting rod bearing test and my car passed so they installed the other Hyundai Recall 966 which was software update for the knock sensor detection system to alert the driver of future issues. Those issues are now current. The software is detecting a critical failure which is why the car is shutting off - entering limp mode, or the engine is failing. On April 9th through the 11th, 2026 my vehicle was inspected by a Hyundai dealership, where a technician identified a developing engine concern and advised me to continue driving the vehicle.

My Hundai Tuscon 2017 was making a whurring sound on the highway, at which time my RPM's were not going over 3. As I was looking for places to pull over on the highway, I heard a loud 'pop' and then my engine started smoking and an intense rattling ensued to where I could hear a series of parts drop out of the bottom of my car. My car began smoking and the engine completely stalled just in time for me to make it to the side of the road. I took it to a local shop for repairs and they showed me three holes in my engine.
