Power Train Problems of Hyundai Tucson - part 2

29 days after I bought a 2018 Hyundai Tucson. The vehicle started making a ticking noise and stopped accelerating. I called the dealership and they said we didn't get a warranty. I said no that isn't correct, no warranty was offered and after seeing all the known engine problems I understand why ken ganley in medina wouldn't offer one. Now not even a month into having this vehicle, I have a brand new 5 year loan and a vehicle that won't move until I put a new engine in it and the dealership won't do anything for me. This is the worst experience I have ever had purchasing a vehicle.

Car has had shaking during acceleration and a noise (rattle/knock/tapping) from the engine for last 18 months. Dealer “could not find any issues” until July 31st 2025 when the engine broke down with a p1326 code (connecting rod bearing failure) and the engine seized. Vehicle is under class action class with extended 150k 15 year warranty on engine for this concern. Had recall performed for the knock sensor detection system as required by class action. Dealership first asked for most recent oil change record (provided) and than informed that Hyundai declined repairs due to full maintenance records not being submitted. Have now submitted full maintenance records to dealer and Hyundai directly since I purchased in 2023 as certified pre owned. All maintenance performed as per factory recommendations in manual. Hyundai still declining repairs without any explanation.

The vehicle is currently in the shop due to safety concerns involving malfunctioning exterior lighting and a serious incident of the vehicle entering limp mode. 1) with automatic headlights activated, all exterior lights shut off while driving at night, posing a significant safety risk. 2) during daylight hours, the automatic headlight system inconsistently toggles between different lamp settings, switching off and on erratically. 3) while attempting to turn left during morning rush hour traffic (on a 40 mph road where vehicles often travel 50+ mph), the vehicle entered limp mode upon acceleration. It bogged down in the middle of both lanes, unable to exceed 13 mph, placing me in a highly dangerous position. After pulling over and leaving the vehicle off for 5 minutes, the issue temporarily resolved upon restart. 4) the vehicle is stored in a garage, and following the limp mode incident, I received repeated “door unlocked” notifications every 30 minutes from 2:30 am to 5:30 am, though the vehicle had not been accessed. These issues are of serious concern and appear comparable to conditions outlined in recall #149 and recall #236, both of which address similar malfunctions related to exterior lighting and powertrain performance. VIN# currently is not within the recalls.

The fuel injectors failed on this vehicle, the vehicle’s engine light came on as I was driving and I took the car to the dealer where I purchased it from. The dealer told me. What the issue was and that they needed to keep the car because it was dangerous to drive.

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 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.

The contact owns a 2017 Hyundai Tucson. The contact stated that while attempting to accelerate, the transmission failed. There were no warning lights illuminated. The vehicle was taken to the local dealer, where it was diagnosed and determined that the transmission needed to be replaced. The vehicle was repaired, but the failure reoccurred. The contact stated that while driving approximately 25-30 mph, the vehicle was making an abnormal rattling and knocking sound that was coming from the engine while accelerating. The transmission was shaking continuously while driving at 10 mph. The vehicle was taken to the local dealer, where it was diagnosed with camshaft and engine failure and needed a cam finish over an advanced timing system overhaul. The contact was informed that the camshaft, cvt, timing chain and tensioner, front valve cover and valve cover gasket, turbocharger, turbocharger gasket, and turbocharger lines needed to be replaced. The vehicle was not repaired. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 92,000.

The car keeps loosing power when it is over 90 degrees outside. On my way to work in the morning it has plenty of power but on my way home around 5 or 6 pm it struggles to gain speed. I’ve already had all the fuel injectors replaced so I don’t think it is related to that. It mainly happens when I slow down but not to a full stop around 20 mph. Then it struggles to accelerate after that.

My 2018 Hyundai Tucson 2. 0l gdi engine with only 79,000 miles was "knocking" and wouldn't accelerate. We pulled over and towed the vehicle to the local Hyundai dealer who declared "oil level good but failed bearing clearance test". Diagnosed with a rod and bearing failure. They submitted to Hyundai motor warranty the vehicle needed new engine. They declined. I know this is covered under the Hyundai engine 2 class action lawsuit with the extended 15 year/150,000 mile warranty as a result of the catastrophic engine failures. I have all oil change service records for every 5,000-6,000 miles while I was the second owner, as well as, have obtained another from the dealer who bought it from a rental/lease company starting at 14,000 miles. Hyundai corporate is claiming "exceptional maintenance neglect" because of one missing oil change record from the rental company that I may not be able to obtain as the paper trail for the rental car company only states first owner was rental/fleet.

The vehicle has a transmission (powertrain) malfunction that first appeared in July 2025, a few weeks after I purchased the vehicle and after the warranty had expired. At the time the issue began, the vehicle had well under 80,000 miles. The transmission slips, fails to properly engage, and cannot provide sufficient power, particularly when accelerating or driving uphill. The vehicle struggles to move forward and behaves unpredictably during normal driving conditions. This defect has put my safety and the safety of others at risk. On one occasion, the transmission failed while I was driving and I became stuck in the middle of an intersection, unable to accelerate, creating a serious traffic hazard. The issue has been reproduced consistently and has persisted despite repeated transmission fluid services. Multiple mechanics have inspected the vehicle and have indicated that the problem is not due to lack of maintenance, but instead is likely caused by the transmission not being properly filled with transmission fluid at the time of manufacture. Despite servicing, the problem continues, indicating an internal or manufacturing-related defect. I have also been in contact with multiple owners of the same make and model vehicle who report the same transmission failure, suggesting this is a widespread issue rather than an isolated incident.

I bought the car used, I took it in for diagnostics on my transmission. They claimed I needed a new one, not claiming I need a new clutch. My car’s model and year match the dct recall problems. But not the VIN. When my car was in the heat or accelerating it had the same issues listed. I believe this is a manufacturing issue.

Won’t shift so that I can gain speed.

Engine making knocking sounds, losing power, no indication of low oil levels until very low.

On a busy highway, my car broke down. It was due to the rod bearings, specifically, the Hyundai theta "extended warranty"/recall issue, or "recall" issue. There is currently a class action lawsuit against Hyundai. I had the car towed to hallmark Hyundai in nashville, TN. I, however, live in louisville, ky and I was making a road trip to nashville, TN. I was told by the service rep in nashville that they couldn't provide me with a loaner vehicle because I would be driving it, back home, out of state to louisville, ky. I paid for a rental car out-of-pocket. Hyundai corporate told me it would take 60 days to get reimbursed. I picked up the car at the beginning of July, 2025, after the engine was replaced by hallmark Hyundai. I was told by hallmark Hyundai that a service employee performed a test drive but it was immediately noticeable to me that there were still issues. I noticed the gears shifting abnormally and problems with acceleration once I first started driving it, post repairs, but assumed I would be told to give it time. Today, [xxx], the car began to have difficulty accelerating once again, and the engine light illuminated. I couldn't accelerate beyond 45 mph. I phoned Hyundai corporate customer care, relayed the issues, and said I needed a rental car the following morning for a job pre-hire meeting and couldn't pay for one since my credit card was already maxed out due to the first out-of-pocket rental. They refused. They told me to work it out with my local Hyundai dealership. The problem with all of this is that the consumer still incurs many hardships even though the car manufacturer is at fault and the dealerships don't always follow the settlement requirements of providing alternate transportation, a loaner or rental. The manufacturer and dealers are not held accountable and settlements that purport consumer recourse are more geared towards the manufacturer staying in business than the consumer being compensated fairly.

The engine experienced catastrophic failure. A piston punctured the engine block, likely due to failure of the connecting rods, an issue known to be associated with the recalled theta ii engine. The engine is still in the vehicle and available for inspection upon request. We were scared and felt seriously endangered during the incident. The engine failed suddenly while we were driving on a busy highway. After a loud clunk, the vehicle immediately lost acceleration and would not respond to throttle input. We had to quickly pull over onto the shoulder while traffic sped past us at high speeds. The sudden loss of power in fast-moving traffic put us at serious risk of being rear-ended or causing an accident. It was a frightening experience that could have resulted in injury or worse. An independent mechanic inspected the vehicle and confirmed there is a hole in the engine block caused by a piston. We brought the vehicle to a Hyundai dealership for further inspection. Still, their communication has been poor, and they have not yet confirmed whether they acknowledge the issue or its relation to the theta ii engine recall. Our independent mechanic has inspected the vehicle and is currently with a Hyundai dealership for inspection. It has not been checked by police or insurance representatives. No third-party inspector has been involved beyond the dealer and mechanic. There were no warning lights, error messages, noises, or performance symptoms before the failure. The engine failure was sudden and occurred without any prior indication of a problem.

Misfire, excessive oil consumption, engine knocking, loss of power/acceleration, gas smell, excessive gas consumption.

On June 3, 2025, I experienced a terrifying and dangerous incident while driving my 2023 Hyundai Tucson hybrid on a three-lane road at approximately 50 mph. Without any warning, the gas pedal became completely unresponsive, and the car abruptly decelerated from 50 to 20 mph. This sudden loss of acceleration was incredibly frightening, especially with vehicles close behind me that nearly collided with mine. There were no warning lights or check engine alerts. Fortunately, I was able to safely cross all lanes and pull over before having the vehicle towed to a local Hyundai dealership. I shudder to think what might have happened if this had occurred on a highway at higher speeds. This is not the first time I’ve experienced serious issues with this vehicle. In February 2024, at about 17,000 miles, I received an urgent alert recommending a system check. At that time, the car was revving while idle and would occasionally lurch at low speeds. The dealership had difficulty diagnosing and resolving the issue, and my vehicle remained in the shop for over a month before they ultimately replaced the oxygen sensor. Since then, the car has continued to lurch intermittently — for example, when backing out of a parking space or in stop-and-go traffic. In fact, approximately 10 minutes before the June 3 incident, the vehicle lurched several times while moving slowly in traffic. When the car began to lose speed during the most recent incident, I pressed the gas pedal all the way down, but it failed to respond at all. I believe the current issue may be related to the unresolved problems from last year and represents a significant and recurring safety concern. I’ve also read in Tucson owner forums that other drivers have experienced similar issues, suggesting this may be part of a broader, systemic defect. At this point, I do not feel safe driving this vehicle. I truly believe this car is a lemon. This vehicle is still at the dealership, but they have not given me any updates yet.

While driving, the vehicle started knocking and jerking, lost power and began to run roughly. The check engine light initially flashed and then turned solid before the vehicle shut off. The next day, I took the vehicle to the dealership for a diagnostic after experiencing problems with knocking when the check engine light illuminated. The codes were p302 and 304 indicating misfiring. The diagnostic tech wrote the problem up as having oil in the cylinder and suggesting engine/turbo replacement for approximately $15,000. 00. The engine has less than 100,000 miles. I asked about the 10/100. After inquiring about the recalls for gdi engines in the 2017 Tucson for rods causing engine fires due to oil leaking into the cylinders, the service agent stated that it was only the 2. 0 and not the 1. 6 with recalls. I said sir it is the same issue: high oil consumption, sputtering and knocking, check engine light indicating misfire. Now the oil is accumulating in the cylinders. He stated that because I am the secondary owner neither the dealership nor Hyundai will correct the problem. However, if I was the original owner the powertrain warranty would cover the repair. The problem with the 2017 gdi, dct in the Tucson is a safety issue for all owners. Escalated the issue to Hyundai motor America, agent kyrillos, who said that he would contact the dealership to check for prior authorization with the dealership to see if they would cover it under the recall. After numerous calls (on my behalf) and finally speaking with kyrillos, I was advised that the dealership denied the repair. I requested supervisor contact and have not had any further communication from the company. I did send a follow up email asking when I could expect to hear from them.

Fuel injectors. It is available for inspection. (please!)this is the second failing of an engine, fuel or powertrain issue. The car was in motion and suddenly just lost power. The first time it occurred about a month after purchased brand new in 2022, the car was coming from a stop light into the middle of an intersection. Driver was thankfully able to glide to side of road since it was early morning and had it towed to dealership. Second time it happened approximately 2 1/2 years later may 29, 2025, the car once again lost engine power at an intersection. Driver, again ,was in a fortunate position to glide off road from a right turn lane. If driver had been in left lanes going speed (55) this would not have ended as well. The car would not restart. Car was towed to dealership. The dealership confirmed that this was a known issue and there was a TSB out. However, there are no kits available to fix it at the moment. And we have no time frame for getting our car back and they have not provided a loaner. The vehicle has only been inspected by the Hyundai dealership. There were absolutely no warnings before either incidents. However, once the car was in possession at the dealership, we received a phone call from Hyundai bluelink saying we had a powertrain issue, which did not make sense since our car had been sitting for two weeks unserviced. If this was related to the same issue they were at least two weeks late. Dealership did not confirm powertrain issue or how anything would be resolved.

The following problems began 5 months ago, 8 months after purchase with about 4770 mileage and current mileage of about 7623: multiple occurrences of check engine light coming on, sometimes setting dtc code, but often not setting code. Multiple occurrences of crash warning light coming on; it may have set a code or codes, but usually not. I think neither dealer was able to reproduce these 2 intermittent problems. Engine light, so far, has not occurred since it was traced to faulty connectors. As far as I know, the crash warning light has not come on since the dealer reduced front camera sensitivity. Also, for the past 5 months there has been intermittent, engine miss, skipping or cut-out. As of this writing it still occurs while driving and will lurch or buck if it happens under acceleration this is not frequent, but it happens erratically and it may happen only once or a few times in one day or several days between. This has not set a dtc code as far as I know; I think the following may be related to the skipping. Once, while coming to a stop, the engine stopped or almost stopped; it bucked when it happened, but continued to run. All warning lights came on for a second or two, then went off, except 3 warning lights and the warning triangle. Although the engine was running, the tachometer and speedometer read zero. The engine bucked as I slowly drove into a parking lot, then I restarted the engine; it seemed ok, then. About 3 weeks later, while driving at slow speed, just as I took my foot off the brake and was about to accelerate, the engine quit. When the engine quit, the audible crash alarm went off with a message saying the engine was not running, press the start button. I started the engine, it did not have normal power. I stopped, restarted the engine and it seemed ok. I have been to the dealer several times because of these problems; dealer is still troubleshooting the last incident. This could cause an accident, especially if it occurs at a higher speed.

The contact owns a 2025 Hyundai Tucson. The contact stated while driving 24 mph, the vehicle shuddered abnormally. After releasing the accelerator pedal and slowing down, the shuddering ceased. There were no warning lights illuminated. Additionally, the auto stop/start feature failed to activate as designed. The vehicle was taken to a dealer where it was diagnosed and determined that the electric oil pump needed to be replaced. The vehicle was repaired but the failure persisted. The dealer then diagnosed the vehicle and determined that the transmission needed to be replaced. The vehicle was repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 15,000.

The contact owns a 2023 Hyundai Tucson. The contact stated while driving approximately 45 mph, the accelerator pedal was depressed while merging onto a highway, but the vehicle lost forward momentum. The contact stated that the message "limited to 20 mph" was displayed on the instrument cluster. The contact depressed the accelerator pedal, and the vehicle failed to respond as needed. The contact stated that the engine was not revving. The contact pulled off the highway and into a parking lot. The contact turned the vehicle off and on, and normal driving was resumed. The contact stated that the failure was intermittent and was occurring while accelerating. Additionally, the contact stated that upon starting the vehicle in the morning, the vehicle would jump forward while still in park (p). Additionally, the contact stated that the horn had stopped functioning after the last loss of forward momentum but had returned to normal function a few days later. The vehicle was taken to a local dealer, however, the dealer was unable to duplicate the failure. The vehicle was not diagnosed or repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 26,500.

While starting and accelerating my 2018 Hyundai Tucson, I began hearing abnormal engine knocking and noticed rough performance. I took the vehicle to an authorized Hyundai dealership, where they diagnosed an internal engine defect. They confirmed the engine issue but refused to cover the repair, citing that I’m not the original owner—despite public information stating that Hyundai’s extended engine defect warranty (related to known bearing failures) applies to all owners for up to 15 years/150,000 miles. This creates a major safety concern, as I drive long distances on highways daily and fear the engine may seize or fail at high speeds. The vehicle remains at the dealership and is currently undrivable. I’ve submitted proper maintenance records, and the issue has been escalated through Hyundai consumer affairs and the better business bureau. This appears to be a widely reported engine defect that Hyundai is not consistently addressing. The lack of coverage and delay in resolution places drivers at unnecessary risk.

When sitting at a stop and then accelerating to leave the stop position, the car will go and then all of a sudden it will stall out and I'm pressing the gas pedal, pressing the gas pedal quite a few times before the car even decides to move. This happens when I'm changing lanes on the highway. . . Merging onto the highway. . . When I'm leaving from a stop sign or a stoplight it happens continuously. It is very dangerous and it can cause a very bad accident. . . . This has been an issue since I had bought the car 3 years ago. . . It seems to be happening more frequent.

On [xxx], my husband and I were driving on [xxx] (highway) in the slow lane, when the engine shutoff without any service engine light warning. It was frightening because an tractor trailer was directly behind the car as we lost power. There was no sounds of engine parts knocking or pinging when the problem occurred. The only thing was observed was (two) 2 puffs of smoke seen from the tailpipe, witnessed by my son who was following behind in his vehicle. The vehicle was not able to start after shutdown and had to be towed to my home. We purchased a new battery after assuming battery failure--with no resolve. The vehicle was towed to(two) 2 repair shops with the same conclusion: seized engine after checking open recalls on my vehicle, I contacted Hyundai to check for assistance. The vehicle is now at the Hyundai dealership in mcdonough, georgia for inspection. I am thankful that my husband and I were not injured or laying in a morgue after this frighten ordeal on the highway when the engine suddenly shutoff/seized.

This vehicle has had numerous problems since I leased it. To summarize, at times the vehicle randomly shifts out of the eco mode, usually into the snow mode. The engine has also raced, hesitated, bucked, rattled and vibrated when trying to change gears. Sometimes, these actions are subtle and sometimes they are borderline violent. This happens more frequently when the engine is cold. Additionally, the aeb system has activated a number of times while in stop and go traffic, even though the vehicle in front was moving forward. On at least 3 of these occasions, I barely avoided being rear-ended by the vehicle following me. The final issue that I have noticed is a problem with the odometer. It has appeared to work normally most of the time, but I have noticed times where I didn't think the odometer accurately reflected the distance I had traveled. I was able to synch the odometer with the trip odometer on a local road that I was quite familiar with. The trip odometer registered 1. 8 miles while the odometer only registered 1 mile traveled. All of these issues happened multiple times and are intermittent. I have had the vehicle to Hyundai dealers on 5 occasions, and they claim to have not been able to duplicate any of the problems that I have been consistently logging in to a "diary" that represents a list of when I have noticed these issues. I have been in constant contact with Hyundai, but they promised to send out a factory rep, then reneged, instead relying on the local service techs. Said techs had the vehicle for nearly 2 weeks, but only drove it for 16 miles (until I called after a determination was made and they hurriedly drove it an additional 22 miles to give the appearance of a more complete exam), using less than a quarter tank of gas. To me, this wasn't a thorough exam and appeared to be a cover-up to avoid having to buy back the vehicle. Note: these problems have occurred on multiple occasions, therefore the date below is the lease date.

While merging onto [xxx] in southington, CT, the vehicle would not accelerate past 25 mph which is very dangerous for merging onto an interstate highway. Luckily, my wife was able to safely pull over onto the shoulder. We shut the vehicle off for a minute, restarted it, and have had no problems since. There were no warnings, and no check engine indicator was displayed. I'll contact the dealer this month at a regular maintenance visit.

On April 12, 2025, my 2018 Hyundai tuson which only has 99,000 miles started stalling out at random speeds. The vehicle stalled going up a hill and would not accelerate it would also not go past 55-60 miles per hour on the highway. There were no check engine lights or codes on the dashboard. The vehicle is also burning oil on 2 occasions when having the oil changed. I feel like my life and others is in danger because the vehicle is stalling at random speeds which could cause a major accident due to this issue. I could be hit by another vehicle while trying to accelerate or merge on the highway. I reported the oil consumption last November and I contacted Hyundai customer care who issued a case number in may 2025 for the stalling issue, they instructed me to take it to the Hyundai dealership to be diagnosed. There is a recall out, but they said my vehicle is not included in it. I took the vehicle to the dealership, and they confirmed the vehicle was stalling and would not accelerate and were able to reproduce the issue. They informed me the vehicle needed a new transmission, and the vehicle only has 99,000 miles. Hyundai and the dealership declined to add the vehicle to the recall campaign for stalling vehicles. I had to cover the cost of $3,000 for a new transmission. I picked the vehicle up on June 6,2025 with the new transmission installed and it is still stalling and won't accelerate past 45 miles per hour.

I’ve been having ongoing issues with my 2016 Hyundai Tucson where the car struggles to accelerate, especially after stopping at red lights or pulling out into traffic. Sometimes, when I press the gas pedal, the car either hesitates badly or doesn’t move at all. A few times it’s completely stalled while trying to make turns or cross intersections, which has been really scary and dangerous. I did some research and found there was a known recall for this exact problem related to the transmission control module software and the dual-clutch transmission. The symptoms described in the recall match mine perfectly, but when I checked my VIN, my vehicle isn’t included. I haven’t taken it to the dealer yet because I’m worried I’ll have to pay out of pocket for something that I believe is part of a known manufacturer issue.

Car is burning oil. Oil change done at 3k and no oil in vehicle at all. Transmission shakes violently on start up and first movement and slips shifting gears. No response sometimes when pressing gas pedal to go.

The engine uses about 3 to 4 quarts of oil before a oil change the it will go in limp mode. I have to get it rest and then add oil for the engine to run right. Also transmission don't want to shift 3 to 4 gear it will be 35 mph to 65 before it shifts. When the car goes in limp mode I lose power going up a hill and almost got rear ended. They won't do anything do to its a used car. No lights came on the dash till it acts up.

There is a significant issue for engine oil consumption that may cause the engines to seize up and require repairs and or replacement. To that end the vehicle purchased has a 15 year 150,000 mile extended warranty included. The vehicle is now in for additional repairs related to the same issues and verification if a new engine will be required.

The transmission failed, and it's only at 70k. This was only diagnosed after being told that my dual clutch was faulty. I had that replaced, only to be told that my actuator was faulty and not the clutch, after haviing paid for the replacement. Now, the vehicle will barely move with rpms through the roof. So not only was ithe vehicle misdiagnosed twice, the cost of repairs was sky high! this could have been avoided. I contacted the dealerships, at they advised that they did everything as Hyundai instructed them. Well, Hyundai was wrong, and now my vehicle doesn't even work.

See attached document for complaint.

Over the past nine months, I’ve been experiencing ongoing issues with my 2018 Hyundai Tucson engine and transmission. After four consumption tests and a flush confirming that the engine is burning between 0. 8 and 0. 3 liters of oil for every 1,000, I was informed Hyundai refuses to either repair the issue or conduct testing to determine the cause. The timeline is summarized below: •February 2025 – I was told by [xxx] my vehicle simply did not have enough oil after the last oil change; •March 2025 – I was informed an initial consumption test needed to be completed; •may 2025 – a second consumption test revealed the engine was burning more than 1 liter per 1000 and a flush was completed; •July 2025 – a third consumption test was completed, revealing that while the engine was excessively burning oil, it was not currently at 1 liter per 1000 based on that test; August 2025 – the oil light came on & I was instructed to put a liter of oil into my vehicle to make it to the certified dealer for next steps. The next steps were another consumption test. Unfortunately, because I was told to add oil to make it to the dealership, I was then informed that this added oil would alter the testing, and we had to start over. •September 2025 – I am now awaiting the results of the fourth consumption test. I have receipts for every 6 months or 7,500 of service since purchasing the vehicle. , despite the engine and transmission being under warranty, the dealership has refused to conduct testing to determine the cause of the issue or remedy the excessive consumption.
