Engine And Engine Cooling Problems of Hyundai Tucson - part 2

I purchased this car from drive time, and when told about a possible recall on the engine I asked about it. We were told that the issue had been resolved. Not even 10 minutes after driving it off the lot the engine started misfiring, we had done a test drive prior to purchasing this vehicle and nothing had popped up on the dash about any problems. We have been unable to get it looked at. I was not sure if a report should have been filed until now. I am unable to produce photos at this time.

Purchased used via carvana in sept 2025, check engine light came on while driving it home indicating a pre-existing mechanical defect. We submitted the claim through silver rock (carvana's warranty company) and brought to their approved mechanic. The recommended the following repairs, several that were denied by carvana/silverrock: spark plugs, alternator, serpentine belt, fuel injection service, electrical ignition coil. A month later check engine light illuminated again and through further diagnostics the mechanic found that 2 of the faulty spark plugs were an incorrect model/fit for our vehicle and reported that information which resulted in replacement being approved (a month after initial request). Fast forward to January 2026 we experienced the widely reported knocking noise while driving coming from the engine and had it towed. The damage is a thrown rod and damaged bearing, which is consistent with the current oil consumption litigation, requiring engine replacement. Our 2017 Tucson 1. 6 l turbocharge is not included in the recall. Furthermore, carfax report shows last oil change reported was 2023. Carvana confirms an oil change is part of their 150 point inspection before a sale, however unable to provide me with documentation and failed to report a record of the work to carfax. There are many instances of negligence on carvana's part from failure to provide record of maintenance, which is also failure to adhere to their standard policy, and declining recommended service directly from their approved mechanic, knowing that this vehicle could be impacted by the well known defects through Hyundai. We are requesting assistance with engine replacement meeting safety standards and ensuring consumer protection.

The contact owns a 2016 Hyundai Tucson. The contact stated that the check engine warning light was illuminated, and there was a ticking sound coming from the front of the vehicle. The vehicle was taken to auto zone, where a mechanic diagnosed the vehicle with a knock sensor failure. The knock sensor was replaced. The mechanic informed the contact that the vehicle was included in manufacturer campaign: cs966 for the transmission control module (tcm). The vehicle was taken to the dealer, who confirmed that the vehicle was included and the software update was performed. After the vehicle was repaired, the check engine warning light was no longer illuminated; however, approximately 30 minutes later, the vehicle failed to exceed 35 mph, and the check engine warning light started flashing. The vehicle was returned to the dealer, and the contact was informed that the software update caused the vehicle to enter limp mode to protect the engine. The dealer informed the contact to drive the vehicle for 30 days or a total of 500 -1000 miles, and if the vehicle continued to enter limp mode or failed to operate as needed, to return the vehicle for the engine to be replaced. There were no additional repairs performed. The manufacturer was not informed of the failure. The failure mileage was approximately 125,000.

I have been adding oil to this engine excessively for more than 3 years. . I have had appointments with the dealer where they flat out told me bring it back when the engine fails. I finally got n appointment and was told the engine needed to be replaced. That was 2 weeks ago. . They are now denying the claim. . . Have had my car for 2 weeks. . No loaner. . And decided to deny what they told me.

Following the knock sensor detection system update, this car has a p1326 code that forces it into limp mode. Occurs during moderate-hard acceleration, e. G. Getting on a highway. The car is limited to ?2000 rpm and ? 45 mph, and rapidly decelerates to that speed if necessary. Acceleration is very limited. This occurs roughly every two weeks, despite having a brand new sensor installed by Hyundai. Hyundai has also allegedly performed cleaning on the sensor and related parts. This has been going on since November, when the recall that installed this update was performed.

Limp mode, knocking , engine light. Only has 62,768 miles on it. I can't fill out campaign 966 or 982 on the official web site for extended coverage.

My 2018 Hyundai Tucson experienced sudden catastrophic engine failure when a connecting rod threw while driving. The engine burned through its oil and the vehicle became inoperable. Hyundai denied warranty coverage for this engine failure because I had not completed the 2021 ksds (knock sensor detection system) recall. I was never notified of this recall. The ksds recall is a software update intended to detect engine knock. It does not prevent mechanical engine failure. Denying warranty coverage due to a software update that I was unaware of raises safety concerns, as engine failure can occur suddenly while driving and creates risk of crash or injury. This appears related to known engine issues in Hyundai vehicles. I am concerned this is a broader safety defect affecting other consumers.

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.

While driving on a public road, the vehicle experienced multiple simultaneous, dangerous malfunctions: dashboard warnings: all lights illuminated, including engine (flashing), abs, traction control, airbag, tpms, and parking brake, which stayed on though disengaged. Engine & transmission: tachometer fluctuated wildly in park; engine revved without accelerator input. Shifting to drive/reverse caused unexpected “kicks. ” vehicle sometimes failed to move when pressing gas, requiring engine restart. Driving issues: speedometer read 0 or jumped inconsistently. Rpm continued erratically while maintaining speed without accelerator. Steering became extremely difficult. I immediately determined the vehicle was unsafe to drive and returned home with it, which was only a couple miles away. Follow-Hyundai advised dealership diagnosis; they suggested a backup camera module will resolve the issues I experienced in entirety, but also in the same email stated that they could not guarantee it would resolve all of the issues I experienced. This is the second major engine/powertrain failure: first approximately ~70,000 miles (full engine replacement), current approximately ~95,000 miles (approximately ~25,000 miles post-replacement). Recurrence indicates a serious, unresolved safety defect. I am deeply concerned for passenger safety, including children. Other owners report similar issues; the attorney general’s office advised reporting to NHTSA. Summary of safety risks: sudden loss of control/power, erratic acceleration, dashboard failures, steering resistance, unpredictable handling, recurrence of major defect. I am submitting this report to NHTSA to request investigation of these recurring defects. I do have video documentation of all of this, as well as all written communication with Hyundai national consumer affairs and the dealership. I am having a hard time uploading them because of the file limits. Please let me know if any of this will be helpful to you.

Component: engine/powertrain/electrical system incident description: I am reporting a recurring, life-threatening "loss of motive power" (dead pedal) in a 2024 Hyundai Tucson (alabama-built). On multiple occasions, the vehicle has failed to respond to throttle input during high-risk maneuvers, specifically while merging into 45+ mph traffic. The vehicle "chugs" and stalls, refusing to exceed 15 mph despite full accelerator depression. This defect leaves the vehicle and its occupants stranded and defenseless in the path of oncoming high-speed traffic. Technical context: this vehicle is currently subject to NHTSA recall 23v-526 (Hyundai campaign 246) for electronic controller damage that can cause "can communication disruptions. " I believe the "dead pedal" failure is a direct result of these communication disruptions between the engine and transmission control modules. Furthermore, Hyundai has issued TSB #24-at-001h-1 for "hesitation when accelerating," yet the authorized dealer (ed voyles Hyundai) has been unable to remedy the defect after 84 cumulative days out of service. Safety risk: this is not a convenience issue; it is a critical safety failure. The unpredictable nature of the power loss makes it impossible to safely judge gaps in traffic. The vehicle effectively becomes a stationary object on active roadways without warning. Manufacturer response: the manufacturer has been formally notified via certified legal counsel. Despite 79 consecutive days in the current repair attempt (since Jan 16, 2026), the manufacturer has failed to provide a fix or acknowledge the severity of the safety risk. An informal third-party evaluator attempted to dismiss the claim despite the vehicle's documented inability to maintain motive power. We are requesting that NHTSA investigate the adequacy of recall 23v-526 and TSB #24-at-001h-1, as these measures have failed to resolve this life-threatening "dead pedal" condition in my vehicle.

At the time of engine failure, my husband was on the offramp between 140n and 24n at approximately 8:30pm. This ramp is under construction and narrow, but state troopers stopped and were able to push the car to the side of the road. As it was nighttime, my husband and /or other motor vehicle drivers/passengers could've been seriously injured. The car did not display any warning lights or signals. The car was then towed home and then to empire Hyundai in fall river, where it was assessed. It was determined that there were 5 outstanding recalls on the vehicle. Hyundai fixed all, with the exception of recall #966, which was issued and not repaired prior to my purchasing the vehicle. Hyundai corporate was contacted by aaron at empire Hyundai. They (corporate) refuses to replace the engine. According to corporate, this should've been fixed by the independent dealer or owner prior to being sold to me.

The car has been diagnosed with internal engine failure by both an independent service center and a dealership service center. The issue was described as a rod timing issue causing knocking, leading to failure of the engine. A light was not on for a majority of the issue but did start flashing before car became completely undrivable. The car was sold to me with this issue and has been driven for nearly 3 years with a power loss issue that was dismissed as turbo lag or other issues. Driving a car with this issue that does not alert with a check engine light is a major threat to driver and passenger safety as it can result in engine seizure and vehicle fires. The engine issues began at the least before 58,000 miles, with total failure occuring at roughly 96,000 miles. Hyundai is known for this issue, particularly in turbo model engines. Only once during ownership of the car did the check engine light come on prior to engine failure. When checked, it was described as a catalytic converter issue. The service center also did an oil change on the car, and the light went off. The check engine light did not come on again for more than a year. The check engine light did not come on until after the issue was diagnosed by the independent service center it was taken to in January 2026.

Burning oil at a rate of 2 qts per 1000 miles driven. Known issue in these models of Tucsons. Not covered by the class action lawsuit as this VIN was not identified. It is burning oil at a catastrophic rate. The problem has burned through multiple catalytic converters that were covered under the warranty but did not solve the underlying problem. Has been burning oil since owning the car a year ago.

On January 7, 2026, shortly after delivery of a used 2015 Hyundai Tucson (VIN [xxx] ), the vehicle experienced immediate mechanical failure while being driven, resulting in sudden loss of power and drivability. Multiple warning lights illuminated on the dashboard at the time of failure. The vehicle became disabled and left the occupants stranded roadside in fairhope, alabama. The exact component that failed is unknown at this time. The failure appears related to the engine, powertrain, fuel/propulsion, and/or electrical systems. The vehicle was not operable after the incident. On January 8, 2026, the selling dealership (sandy sansing Nissan, pensacola, florida) towed the vehicle back to their dealership. The vehicle has remained in the dealership’s possession since that date and is available for inspection upon request. This sudden failure created a significant safety risk due to loss of propulsion while in traffic and exposure to roadside hazards. The problem has not been independently repaired or evaluated by the consumer. No manufacturer inspection has occurred to the consumer’s knowledge. The dealer has not provided a diagnostic report or repair findings. No warning lights or symptoms were disclosed prior to delivery. The failure occurred almost immediately after delivery. The vehicle was sold and delivered by a licensed dealership. The sale is currently in dispute because the vehicle became disabled almost immediately after delivery due to this safety-related failure. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The car keeps randomly dying. Completely loses power even when driving.

The engine, specifically cylinder # 3, has had a catastrophic failure at 114,000 miles. Engine repair shops and engine experts have determined the only fix is a complete engine replacement. Cost estimates are $8500 for a new engine + labor estimated at $2000. Scrap value is estimated at $1000 - $1500 the dealer from whom we bought the car in late 2015 said it is out of warranty. This is unacceptable. Please, please issue a recall on the engine of this vehicle. The vehicle is available for inspection if requested. Failure was catastrophic problem has been confirmed by engine experts the car is not drivable to a manufacturing facility the engine has not been inspected by police nor our insurance company there we no warning lamps or messages symptoms include shuddering at initial acceleration beginning at 75,000 miles dealer said there was no problem and recommended and performed a transmission fluid change.

On my husband's way home from work he explained to me that the car had a "hiccup" and then an engine light blinked on, then it died at an intersection. He was pretty close to home so he got it started again and drove it home. He replaced spark plugs and coil packs and it still had a misfire. We took it to an auto repair shop where they did a scan and told us it had a dead hole in cylinder 2 and that it needs a full engine replacement. The car also had an oil change just before thanksgiving. My husband checks oil regularly and added a quart a month before the oil change and it seems to consume more oil then it should.

The contact owns a 2017 Hyundai Tucson. The contact stated that while driving approximately 70 mph, the vehicle lost power, decelerated, and the check engine warning light started flashing on and off. The vehicle was parked on the left shoulder of the highway and later driven to the right shoulder with the assistance of a state trooper. The vehicle was later towed to the local dealer, who diagnosed that the engine had failed and needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure, but no assistance was offered. The contact was informed that the vehicle was previously serviced under NHTSA campaign number: 21v727000 (engine). The contact stated that the vehicle had experienced the failure listed in the recall. The failure mileage was 66,000.

The engine is burning excessive oil. Down 3 quarts over approx. 3,000 miles. Mechanic verified there are no leaks - it is burning the oil.

All four cylinders misfired in my car while driving causing the catalytic converter and all four fuel injectors to need to be replaced. My car suddenly stopped driving in a rural area with only a few minutes of warning when the engine light came on. I was not even able to drive to a nearby shoulder. I was stranded on the side of the road in 5 degree weather until a tow truck could come.

Purchased this car used 3 years ago. Followed owner's manual for oil and filter changes. On 1/2/26 the engine seized, had it towed to Hyundai dealership and they will not approve a replacement for the engine because they said I hadn't followed maintenance guidelines. I submitted all receipts and they still are denying. I had the ksds and all Hyundai campaigns addressed which was to extend the warranty and they still deny. No warning lights whatsoever came on until the engine seized on the parkway. Hyundai knows there is an issue with these engines but still won't step up.

My 2024 sel hybrid has a very annoying acceleration delay after a full or partial stop. The delay has occurred many times. It is present no matter which mode the car is on. It is not a matter of slow acceleration, but a 1-2 second delay of anything happening after I press the pedal. This could be a safety issue when you're at a stop sign and you need to proceed and you can't go.

I am having issues with the main window switch for the second time. 1 out of 3 windows goes down but not back up. Also I took it for a check up and found nothing but the engine is making a loud noise and shakes the car when in drive. I don’t feel safe driving this car sometimes.

Numerous issues with this vehicle. Now, when having oil change, told by the Hyundai service center that it is using excessive oil and may need a new engine. In researching this problem, have discovered Hyundai has had several problems with excessive oil consumption in their many of their Hyundai vehicles, including the 2016 tuscan.

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.

Engine lost power suddenly on the highway. Vehicle entered limp mode and became limited to 45mph and reduced acceleration.

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.

On December 27, 2025, while driving, the engine suddenly lost power and the vehicle entered limp mode and became undriveable. A warning light appeared and diagnostic code p1326 was later confirmed, indicating engine bearing failure. The vehicle could not be driven safely and required towing to a Hyundai dealership the following day. The engine failure caused a loss of propulsion safety risk. The vehicle remains out of service pending a full engine replacement. The vehicle is available for inspection at a Hyundai dealership.

I am the original owner of this car and in June 2025 I brought my car to Hyundai from noises and they told me it had no oil despite me being up to date with oil changes on the vehicle. They told me they were going to do an oil consumption test and once they did that the engine was denied. 6 months later 3 days after an oil change and no check engine light on, the engine fails while I’m on the side of the highway. This car is not safe. Check engine light was not on and I am always up to date with my cars maintenance.

Hello, my 2019 Hyundai tuscan I have owned for 3 years-4 years. Unfortunately it is a gdi motor, it uses oil so bad, even though I do change the oil every 3,000 miles, and do every maintenance on the vehicle that is told to me done, ever time I change the oil it is low, even though I top it off through out the 3,000 miles. I have no leaks at all and it is just evaporating, I do not think this is right for a 2019… there is several issues and concerns from other buyers with this issue. There should be a fix to this, ASAP.

Oil light comes on between changes at about 1500 miles before needing one, oil does not show on dipstick and have to repeatedly put on in engine. Chance of engine seizing or jumping time.

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.

Car engine seized and lost all power going 60mph down the highway at night with my child in the back seat. I have poured quarts and quarts of oil in this vehicle because it burns oil at an alarming rate until it eventually runs dry and the engine seizes. This is extremely dangerous and luckily my child and I were able to drift to the side of the road without harm and injury. Very discouraging that there are thousands of these cars and engines on the road that can literally seize up at any minute. Maintenance was performed and kept up with. The oil pressure light had been flashing when the vehicle turned but was flashing even when oil had just been changed. These engines are dangerous and have people in a financial hard spot. I still owe $16k on a car I can no longer drive and that Hyundai is saying due to owner maintenance will not get an engine replacement. The facebook group Hyundai oil consumption test has thousands of people dealing with the same exact issue on these cars and engines.

Oil component failure causing extreme heating within the engine and catalytic converter which poses risk for engine fire. This oil consumption issue was addressed by the dealership who ran a test to see how much oil was consumed. The test results showed that the vehicle was burning oil at a high rate and would ultimately result in engine failure. The low-oil light has never come on indicating a need for an oil change. Despite this, I have constantly pulled my own dip stick and got changes every 2,000 miles. For this make and model, they required a change every 5,000 miles. When I notified Hyundai corporate over this concern. They claimed due to it being outside of warranty, that it does not matter what my engine light has been doing since I got the car, nor the issue with the oil consumption, they refuse to address any of these problems as being a manufacturing problem. The maintenence has been kept up since I got the car, so the manufacturer is not acknowledging the constant issue with Hyundai tuscon engine dangers. If a fire were to occurr, I was told this is not Hyundai's responsibility due to me not being the first owner and it not falling within warranty. After the combustion test, Hyundai claimed that they refilled my oil. When I checked my dip stick after only driving 100 miles, the image attached will show the resulting levels. My oil light is still not coming on despite this. Even when it has been much lower than the pictured level. This, paired with the super heated catalytic converter due to the oil consumption, is going to cause an engine fire and is not fair to the consumer.

While operating the vehicle, the engine shut down. Complete loss of power. Engine would restart, stall and then not restart. Vehicle immobile. Vehicle towed to dealership since could not be driven. Strong smell of gasoline.
