Power Train Problems of Hyundai Tucson - part 1

I recently purchased vehicle and when checking recalls from my local Hyundai dealership I was advised that there was two previous attempts to have engine replaced due to knocking and it was denied this recalls is the 209 I escalated to Hyundai corporate and after taking to a Hyundai dealership and paying for a diagnostic test they advised car doesn't have oil pressure and the oil pump needed replaced and Hyundai corporate denied repairs saying this didn't pertain to recall 209 because my engine is a 1. 6 liter and it was ok only to the 2. 0 engines, I would like to report this and ask for help please.

My car on the expressway wouldn't go over 40 and this was happening intermittently so my car was unsafe. No check engine light but it was just at the dealership for an oil change. Has. Been an ongoing problem since I bought the car! smells, gets hot!.

I've taken the vehicle to several mechanics for engine-idling when turning, going up-hill. I've purchased new plugs, lines, engine cleaners, no-one can figure it out. The oil now has engine shavings even though the oil was recently changed. The car broke down today.

High oil consumption, taken to dealer for oil consumption test, have to drive vehicle 1000 miles , then take vehicle back to dealership to see how many quotes of all I’ve burnt or lost recheck oil levels.

I purchased a brand new vehicle with only 12 miles on it. Less than 72 hours later I had to have it towed. I turned the vehicle on and tried to put it in drive and 2 error messages came up. One was the check hyrid system and the other was a check engine. The diagostic tool on the car says it is related to transmission. The dealership doesnt have time to look into it yet and the manager from the dealership I bought it from offered no solutions since I travelled home to another state.

The vehicle is experiencing excessive oil consumption and increasingly severe engine performance symptoms. The oil level drops rapidly between changes, but the loss is not due to external leaks. The engine burns oil internally, causing residue buildup and damage to other components — specifically the intake manifold and catalytic converter, which the dealer has now recommended replacing. These issues align with the symptoms addressed in Hyundai campaign 966 (engine monitoring / knock sensor detection system), which is intended to detect early bearing wear and related oil consumption defects. However, the dealership refused to perform the required campaign diagnostics (bearing inspection, ksds verification, and oil-consumption test) without charging a diagnostic fee. Even though the engine has not yet fully failed or entered limp mode, the excessive oil consumption is already causing secondary damage to emissions and intake components. If left unresolved, this can escalate to engine seizure, catalytic converter overheating, or exhaust-related fires due to unburned oil entering the converter. These are clear safety hazards that can result in loss of power, smoke, or fire while driving. Multiple Hyundai owners have reported identical problems — excessive oil loss, residue damage to emission systems, and dealer refusals to perform campaign 966 inspections. These patterns indicate a systemic engine defect that leads to downstream component failures, not isolated wear. Replacing the manifold or converter does not correct the root cause, as oil consumption continues after replacement and will likely damage new parts. The dealer’s refusal to perform the manufacturer’s required diagnostics and their attempt to charge for unrelated repairs prevent proper defect identification. This is a serious and ongoing safety issue affecting Hyundai Tucson and other models with the same engine family.

My Hyundai’s replacement engine, installed under a recall a little over a year ago, is now failing again. Hyundai’s service department was the only shop to ever work on the engine. There is visible silicone drooping from the area where the head and block were torqued down — a defect hidden beneath the engine cover that isn’t removed during normal maintenance. Hyundai corporate acknowledged silicone use would be “shoddy work,” yet refuses further review, stating they’ve “never had a customer dispute something within 18 months later. ” if Hyundai engines arrive sealed and shops don’t handle insulation, silicone should not be present. This may indicate poor workmanship or improper installation on recalled engines. I request NHTSA review this as a recurring safety and workmanship issue on Hyundai recall replacements.

My 2017 Hyundai Tucson limited 1. 6l turbo (with 7-speed ecoshift dct) has ongoing transmission problems. The vehicle hesitates, jolts, and sometimes fails to accelerate from a stop, which creates a serious safety risk when entering traffic or crossing intersections. The problem has been reproduced and confirmed by the Hyundai dealership in fairfield, CT. They diagnosed the transmission and recommended a complete replacement at a cost of over $7,000. This issue matches the defect described in NHTSA recall 16v628000 and Hyundai service campaign t1b, which involved the same 7-speed ecoshift dct in 2016–2017 Tucson models. However, my VIN was not included even though I am experiencing the exact same safety defect. No warning lamps appeared before the hesitation/judder began. The safety risk is significant because the vehicle can fail to accelerate as expected in traffic, increasing the chance of a crash.

Excessive oil consumption, full synthetic oil last less than 2000 miles. Transmission takes some time to respond when start driving from a stop. Car shake a bit.

Car would not go over 25 mph. Had to pull to side of the road. I had to turn the car off and on then it ran normal.

While almost at a complete stop in the process of putting my 2019 Hyundai Tucson in park at my friends home to drop her off, the car involuntarily surged/accelerated forward over a cement curbing and landscaping timber and slide down a small incline into a tree and landscaping boulder! after looking on line concerning the malfunction it seems there are abundant claims from other 2017-2019 Hyundai Tucson owners that have experienced this exact mechanical defect under this frightening description of a surge or acceleration out of the drivers control! it's the craziest, scariest thing ever. We have taken the car in for a recall concerning the check engine light regarding the catalytic converter prior to this incident. The car is well cared for and maintained and has never been in any accident.

Fuel injector failure. Car was losing power completely when pressing the gas pedal then would suddenly catch and go again. Then go very slowly with little power, almost got into an accident because of the loss of acceleration. They replaced the fuel injectors and it is now happening a second time with the check engine light coming on again. A recall needs to be made! several of the same complaints on here!!!!!!!.

I was driving on the highway, about to change lanes, when I looked in my rear view mirror and saw black smoke coming from my appeared to be my exhaust. I immediately started to pull over, and that is when the oil light first appeared on my dashboard. By the time I had put the car in park, the check engine light had also appeared. After calling my boyfriend and a tow truck, I exited the vehicle and noticed a large pool of oil by my front tire. With the car on the tow truck, I could see oil continue to drip out. The car was towed to the local Hyundai dealership. Since this occurred on a Saturday afternoon, the service dept. Was closed, and Hyundai called me on Monday, Aug 11, 2025 to explain that I should contact the auto mechanic that last changed my oil, as the oil plug had fallen out, and my engine had seized. (had I not noticed the smoke right away, I could have been in an accident on the highway when the engine seized. ) I explained to Hyundai that I had my oil changed 3,000 miles ago, and hadn't seen any indication of oil leakage, nor had the oil light come on prior to the incident on Aug 9, 2025. Hyundai insited I contact the oil change mechanics as it was clearly a craftsmanship defect, not the fault of Hyundai parts or material. Hyundai provided photos showing the oil plug was still laying on the block. I visited superior auto (mechanics that did the previous oil change) and they also deny responsibility due to the fact that the car drove fine for 3,000 miles without any indication of oil leakage, so there is no proof of fault craftsmanship.

I recently purchased this car and just took it on our first highway trip of about 1100 miles. I experienced three problems that are a safety concern. 1. "need to take a coffee break notification. " this comes on frequently and is distracting. No need to have that come on. When driving in heavy traffic at speed, this is too distracting. There is no way to turn it off. 2. Camera focused on the driver. If I take a drink from my water bottle, looking around the water bottle to see the road, the camera can not see my face/eyes. It then shuts off my cruise control, makes a noise, scares my wife, and distracts me from driving. This has happened to me in heavy urban traffic going through cities on my last trip. 3. The cruise control is linked to communication from outside the car. When driving in the mountains, there are times when the signal is lost, the cruise control stops working, the car emits a noise signally a problem, my wife screams, I lose concentration on what is going on as the car decelerates quickly and the semi truck behind me comes very close to the rear of the car. Potential accident caused by this silly system. There is no way to disable "adaptive cruise control" and resort to a system that does not rely on outside communication. The car has about 3000 miles on the odometer and I am ready to trade it in/get rid of it. I am greatly disappointed.

My car is a 2023 Hyundai Tucson plug-in hybrid with approximately 75,455 miles on it. The car is stuck in neutral and will not switch to any other gears. The car also will not turn off fully. I basically got stuck/stranded and could not move. Had to be towed.

The car will fail to accelerate when turning at a stop and starting at times. It’s very dangerous b/c you can be at a complete stop on the highway and try to start going and the car will sputter out. There is no doubt that something is wrong with the transmission and has been for a year but didn’t register until 12,000 miles later. The car only has 70,000 miles in it. I kept taking it to Hyundai to be looked at and they kept telling me it was just how the dual clutch transmission works. Now a year later they say it’s registering as a problem but don’t want to cover it under the warranty b/c I’m a second owner. If I was the original owner, it would be covered. If you look at the history of this year and make, you can see there have been issues with this car. I am extremely upset they aren’t willing to cover the cost. This is my [xxx] daughter’s car and this has been extremely dangerous to drive. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Excessive oil consumption no leaks its buring oil.

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.

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.

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 2013 Hyundai Tucson. The contact stated while driving and exceeding 30 mph, the transmission was slipping out of gear. There was no warning light illuminated. The vehicle was towed to a dealer located in canada, where it was diagnosed that the transmission sensor had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 60,000.
