Owners have filed 1,456 complaints
about the 2017 Hyundai Tucson with NHTSA between 2016 and 2026.
The largest single group is the engine & cooling.
Across this model's run it ranks 1 of 22 worst.
The letter says how bad. This says what kind — whether this year drew
an unusual number of complaints, unusually dangerous
ones, or failures that arrived unusually early.
The dashed ring is 50 — the national norm. Further out is worse.
Complaint volume — 100
Against the median year of the Hyundai Tucson. 50 means typical for this
model; 100 means roughly double.
Severity — 29
5.7% of these complaints
involved a crash, fire, injury or death, against a national rate of
9.7%.
Early failure — 100
62% of failures with a mileage on record happened under
36,000 miles, against a national rate of
29%.
NHTSA files every complaint against a named sub-assembly, not just a
system. This is the difference between knowing it was "the engine" and
knowing which part of it — the list to hand a mechanic.

NHTSA investigations into the 2017 Hyundai Tucson
An investigation is the step before a recall: the agency has seen enough
complaints to look into a pattern itself. An open one means it thinks
something may be wrong and nothing has been fixed yet.

Engine Fires
On March 29, 2019, the Office of Defects Investigation (ODI) opened two Preliminary Evaluations (PE19-003 on Hyundai and PE19-004 on Kia) to broadly investigate incidents of non-crash fires (regardless of origin or operational status of the vehicle) on various model year Hyundai and Kia vehicles. During the PE investigations, Hyundai and Kia issued several recalls to address vehicle fires, including those due to engine failures involving various engine types. The remedies for the engine failure recalls typically involve engine inspection (to detect existing damage), and if necessary, engine...
Recalls on the 2017 Hyundai Tucson
A complaint is one owner's allegation. A recall is the point at which
the manufacturer or a regulator agreed the defect is real and dangerous
enough to fix for free — however old the car is.

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.

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.

STEERING
Subject: Formal Safety Complaint Regarding Steering Failure – 2017 Hyundai Tucson To Whom It May Concern, I am submitting this complaint to request that the National Highway Traffic Safety Administration (NHTSA) investigate a potentially serious safety defect involving the Motor-Driven Power Steering (MDPS) system in my 2017 Hyundai Tucson. I am the second owner of this vehicle. The vehicle currently has approximately 61,000 miles and remains within Hyundai's 10-Year/100,000-Mile Powertrain Warranty period applicable to subsequent owners. Approximately two years ago, the vehicle's engine was replaced under a Hyundai safety recall. Recently, I began experiencing intermittent steering problems in which the steering wheel becomes extremely difficult to turn and appears to momentarily jam or lock while driving. This condition significantly affects vehicle control and creates a serious safety hazard, particularly during turns, lane changes, or emergency maneuvers. I brought the vehicle to Advantage Hyundai in [XXX] for diagnosis. The dealership determined that the vehicle had a Motor Position Sensor Error (Diagnostic Trouble Code C2401) within the Motor-Driven Power Steering (MDPS) system. The dealership informed me that the repair is not covered under the vehicle's warranty and declined to repair it. The dealer also submitted a request to Hyundai for goodwill assistance (Prior Authorization No. XXX), but Hyundai denied that request. I subsequently contacted Hyundai National Consumer Affairs (Case No. XXX) seeking assistance. Unfortunately, Hyundai also denied my request despite the relatively low mileage and the serious safety implications of the steering malfunction. My concern extends beyond the cost of repair. A malfunction in the electronic power steering system that causes steering to bind, jam, or become difficult to control presents a significant risk of a crash, injury, or loss of life.

Murrieta, CA
ENGINE
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.

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.

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.

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)

STRUCTURE:BODY
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.
