general problems of the 2016 Hyundai Tucson - part 1

All dash warning lights are on and dash lights have a intermittent bright light surge. Hard to shut off engine and have to disconnect battery for electric power to shut off. Very noticeable hesitation in acceleration starting to drive.

Hyundai Tucson sport 2016 gdi engine. I am the original owner of this truck I have taken care of this truck so much it being my first brand new purchase. No oil leaks nothing! when I first purchased the vehicle I noticed that it would stall when I would accelerate but did not think too much of it since it was brand new. A few years passed started to notice frequent oil changes were supposed to be made. Another few years turbocharger went out had to get it replaced. The engine consumes so much oil at first I thought it was because the turbocharger was out so when I got it fixed I thought that would fix that issue and it didn’t. I got an oil change March 2, 2026 and on March 21, 2026 I was on the highway and the truck started to shake really bad I exited the highway went straight to the oil place they said I had no oil on the dipstick I got another oil change (expensive) and when I turned on the car to leave the car shook again and the engine light was flickering on and off and finally stayed on the dash board. Barely made it home. Got a tow truck to tow it to Hyundai dealership they told me they will not see it unless I pay the diagnostic fee of $200 and even then they think it’s the engine with everything I described to them. They said since there are no recalls on the Tucson that Hyundai will not do anything for me I would have to pay out of pocket for everything. Had to pay the tow truck again to tow it to my house ($250). My car has all the symptoms all the other cars have that they have recalled. This is a huge safety issue because I drive on the highway a lot and everyone knows a car with no oil is extremely dangerous.

"on [xxx], my 2016 Hyundai Tucson (VIN [xxx] ) experienced severe engine power loss and mechanical noise under load while driving uphill, creating a dangerous safety situation. This occurred 2 days after a dealer visit (February 19, 2026) where an open ksds service campaign (TSB hce22-14-e600-tl, issue 10d021) — directly related to engine monitoring — was left incomplete. The dealer subsequently denied an engine evaluation citing mileage over 150,000, despite the open campaign having no mileage restriction and despite a prior verbal commitment to cover repairs. Multiple follow-up attempts by phone, email, and whatsapp have been ignored. " information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

My car had a ksds knock sensor detection system campaign 966 installed in 2022 specifically to active if having rod bearing wear. Towed my car to Hyundai under the txxm warranty and they said my bearing clearance was ok and I need new lifters and timing chain cost for repair $2900. I have asked for the full rod bearing wear test report and they will not provide it. They have had my vehicle for 20 days now and I am out of work on disability. Hyundai service center is generally expected to provide you with a report following a rod bearing wear test (often referred to as a bearing clearance test or by a related service campaign, such as t6g or TSB 21-em-004h). Here is what you can expect regarding reports and documentation: documentation of results: the dealership should provide a copy of the results, specifically noting if the bearing clearance passes or fails. Proof of inspection: if the test is performed under a recall or service campaign (e. G. , campaign 966, 982, or t6g), they are required to document the inspection, which you can request for your records. Evidence of damage: if the test results in a failed diagnosis, technicians often take photos of the engine internals, such as metal flakes in the oil pan or excessive wear, which are used to support the warranty claim. If the test passes: if your vehicle passes, ask the technician to print a copy of the results. If the test fails: a formal diagnosis of rod bearing failure, confirmed by this test, is required for engine replacement under the extended 15-year/150,000-mile warranty. Hyundai - recalls +3 this is a safety issue without the full rod bearing report to consumer.

Car died/lost power while driving in traffic 11/28/25. Good samaritan was kind enough to push me off the road out of traffic. Car was towed to Hyundai dealer that day, then 12/1 told engine failure, required engine replacement. Class action lawsuit settlement for engine replacement, but denied by Hyundai because of "neglect", since I am not able to locate all of the service records that they request. Known faulty rotating assembly, and Hyundai has implemented concerted practice of denying warranty coverage for failed engine. Now having to pay almost $8k to replace with new engine, but concern that new engine will have same issue. (multiple posts about this). There was high potential for significant traffic collision, injury due to sudden, catastrophic engine failure. Traumatic experience.

While driving on the highway at normal speed, the vehicle suddenly lost power and shut off without warning. There were no warning lights or messages prior to the loss of power. I was able to safely pull over, but the engine would not restart at that time and the vehicle required towing. The sudden engine shutdown occurred in active traffic and created a safety risk due to loss of propulsion. The vehicle later restarted, but I brought it to an authorized Hyundai dealership for inspection. The dealership diagnosed internal engine damage, including piston ring failure and cylinder wall scoring, and advised that the engine would need to be replaced. Since the incident, the vehicle has shown intermittent oil pressure warning lights and reduced performance. The issue has been confirmed by a dealer inspection. The vehicle is currently not considered reliable or safe for regular driving.

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).

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.

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

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.

1. "transmission or ecu" 2. There is a lag and sometimes almost stall when accelerating from a stop. I was turning into a lane from a stop sign and the car decided to not move for 3-4 seconds after pressing accelerator. If people had come around the blind corner when that happened I would have been t boned. 3. All four people living in my house. . . . . . And our mechanic. Yes 4. No, because were not paying for something that has had a recall. 5. We inherited this car from my grandmother and she knows nothing about cars so she never thought anything was wrong. Since the day we got it, it has been doing the same thing "dct control logic update & p0128 dtc logic update (recall 149)" #17-01-023.

1. December 2024: Hyundai dealership diagnosed my transmission as defective (unable to shift properly) and recommended a full replacement. Despite this, they assured me the vehicle was "safe to drive" without disclosing risks. - unedited dealer text: "the tech said he doesn’t think it will break down or leave you stranded, he just can’t get it to shift correctly. " - no warnings were given about prolonged use, highway driving, or potential failure. 2. Post-repair damage: after relying on Hyundai’s advice, the transmission worsened, causing additional damage (e. G. , radiator failure). 3. Recall negligence: my VIN was wrongly excluded from recall 16v-628 (transmission control issues), despite exhibiting identical symptoms. They didn't cover repairs, despite their technician confirming the defect. The safety impacts are as follows: - sudden loss of power while driving (e. G. , inability to accelerate or shift). - increased crash risk due to erratic transmission behavior. - Hyundai’s failure to warn put me and other drivers in danger. I am requesting: - investigate why my VIN was excluded from recall 16v-628. - force Hyundai to reimburse repairs and extend recall coverage. - require Hyundai to issue clear safety warnings after faulty repairs. Attached is the following: - the radiator repair invoice. - proof of text from Hyundai. - proof of my VIN being excluded from recall. - quote for my transmission repair.

The contact owns a 2016 Hyundai Tucson. The contact stated that while driving at undisclosed speeds, the transmission started slipping while accelerating. There were no warning lights illuminated. The contact stated that the failure was related to NHTSA campaign number: 16v628000 (power train, electrical system). The contact called an independent mechanic who provided a printout of a recall. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 108,000.

When accelerating, like taking off from a red light or through a turn, my car begins to shake like it’s unable to change gears correctly, and sometimes leads to the car stalling in the middle of the street and intersection putting my in danger of being hit from other drivers. It’s also happened that when I press the gas after being stopped at a light, my car rpm goes up but I don’t move and then the car jolts forward quickly. This has been happening for years and when I take it to Hyundai they tell me “that’s just how the car runs” which seems incredibly unsafe.

My backup, my reverse is not working after 30 minutes the car is running.

Loss of power, transmission slipping. Unable to get car to move creating hazard. Happened 5 times. Diagnosed by dealer as systemic transmission component failure and known issue. Many of the same complaints on internet, code p1921.

Vehicle started to shake and lost acceleration. Gave engine code p073f unable to engage gear 1. Hyundai shows recall campaign for this issue but dealer refuses to acknowledge it, and says it needs new transmission. They state transmission damaged clutch rather than clutch damaged transmission.

Oil consumption is excessive it has caused the engine to have a knocking noise even though routine oil changes have been up to date. Yes available for inspection. This may cause the engine to seize at any given point while in motion. No, I have not been able to take the vehicle to a dealership yet. No, vehicle has not been inspected. No, no check engine/warning light has turned on. Knocking noise began June 28th 2024.

My Tucson has been using an absurd amount of oil for the past 30,000 plus miles I had it in the shop for repairs for the exhaust/ turbo leaking due to broken stud bolt that finally was covered under warranty. But did nothing for the burning of oil. No oil leaks. It used a quart for every 500 miles. Now no warranty left I have a cylinder #1 misfire and have replaced sparkplug and will not come out of limp mode. Within a mile of driving the plug is oil fouled and goes back into limp mode. Probably will get no help from Hyundai to rebuild/ replacement of the motor.

The contact owns a 2016 Hyundai Tucson. The contact stated while driving approximately 40 mph, the vehicle lost motive power. The contact depressed the accelerator pedal and the vehicle lunged forward. The contact stated no warning light was illuminated. Additionally, the contact stated that when the vehicle was stopped, after depressing the accelerator pedal, the vehicle hesitated and then lunged forward. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was informed of the failure. The contact researched online and related the failure to NHTSA campaign number: 16v628000 (power train, electrical system); however, the VIN was not included. The failure mileage was approximately 140,000.

The contact owns a 2016 Hyundai tuscon. The contact stated that while driving at various speeds the vehicle would begin sputtering and the transmission would begin slipping. The transmission would also slip when attempting to accelerate after being parked or idle. There were no warning lights. While driving approximately 45 mph the vehicle suddenly began going in reverse. The contact immediately placed the vehicle in park to turn off the vehicle. After restarting the vehicle the contact attempted to drive it but failed to accelerate. The vehicle was only able to be driven in reverse. The contact reversed into the nearest parking lot. The vehicle was towed to a certified mechanic where it was diagnosed that the transmission failed. The transmission needed to be replaced. The vehicle had not been repaired. The manufacturer was not made aware of the failure. The failure mileage was 90,000.

The contact owns a 2016 Hyundai Tucson. The contact stated that after the vehicle came to a complete stop, the accelerator pedal was depressed, and the vehicle lurched forward but hesitated to accelerate immediately. An unknown warning light illuminated, and the check engine warning light was later illuminated. The vehicle was taken to an independent mechanic, who retrieved dtc code: p073f (unable to engage gear 1), but no repair was recommended. The vehicle was not repaired. The manufacturer was not made aware of the failure. The contact related the failure to NHTSA campaign number: 16v628000 (power train, electrical system) however, the VIN was not included in the recall. The failure mileage was approximately 93,000.

Vehicle transmission prolongs shifting from 1st to 2nd gear, and from 2nd to 3rd gear. Vehicle only has 55000 miles on it and we are second owners of the vehicle. This has been on ongoing issue with the vehicle that we attributed to design but a month ago, the check engine light came on. We took is the ray skillman Hyundai who diagnosed that the transmission was the cause of the check engine light and that the entire transmission will need to be replaced at a cost of a little over $7000 to us. The original warranty on the car offered a 10-year, 100,000 mile warranty but ray skillman Hyundai nor Hyundai corporate will replace the transmission without charge. We also know of many other issues related to transmission components of other Hyundai vehicles. The vehicle puts at risk because the unexpected pause puts the drivers behind us at risk of running into us.

The engine sign keep blinking on the dashboard, I went to auto zone, they scan it and say that the power train system with code p1326 glow relay short circuit is the problem. This would be the second time it comes on. The first time it came on but then stopped in a few days but it’s on back again.

The contact owns a 2016 Hyundai Tucson. The contact stated that, attempting to accelerate from a stop upon depressing the accelerator pedal, the vehicle failed to immediately accelerate as intended before suddenly lurching forward. No warning lights were illuminated. The vehicle was taken to the dealer, who was unable to diagnose a failure. The dealer informed the contact that the vehicle was functioning as expected. The vehicle was taken to an independent mechanic, who was unable to diagnose a failure. The vehicle was not repaired. The manufacturer was notified of the failure, and a case was opened. The failure mileage was 53,000.

A/c failure & heat failure which resulted in an accident. Was not the thermostat.

The engine began to make a knocking noise. Upon our inspection, the vehicle had lost all oil. Vehicle was towed to our local dealership. Dealership informed us a bearing had become worn causing rapid oil loss and a rod to break, sending metal shards into the engine compartment. Engine could have seized up or caught on fire, had the vehicle continued to run. Dealership informed us of other Hyundai recalls for the same issue, however we were told our year/make/model was not included. Vehicle had been at same dealership 2 months prior for a heat/ac issue and a complete inspection was completed. No indication of bearing, oil, or engine issue was noted. No warning lights came on at any point.

Vehicle has 101k miles on it, just over the 100k Hyundai warranty. Vehicle began shaking and sputtering while driving, and check engine light illuminated, I was able to get it to a local mechanic. Mechanic said it had multiple codes (p300, p302, and p304). They did a compression test and said the engine has internal failure and should be replaced; quoted 13k to replace. I had it towed to the Hyundai dealership where I bought it, and they are investigating it. The service manager told me even with perfect maintenance records, Hyundai will likely deny a goodwill claim to replace the engine. Looking at all these engine failure complaints for this year model, it is clear this is an ongoing problem and Hyundai needs to issue a recall.

51k miles and engine went out on the highway. No lights or warnings until afterwards. We were able to safely pull over onto the shoulder and had the vehicle towed to the dealer for servicing.

Engine heating problems, electrical problems and now engine failure, the vehicle is no longer safe to drive. The vehicle is available for inspection. Other vehicles of same make, model, and year have been recalled for these issues however mine has not. I feel it has the same types of issues and safety concerns which should be recalled. The issues began with electrical problems inside the vehicle, random check engine lights coming on then off and other lights popping up in the dash board, the car was not accelerating properly, took the car in and they could not find a problem or fix it. The engine began heating and the speed of vehicle was also being affected. The car would randomly slow down quickly while on the highway at 70 mph which happened a couple of times and was not safe at all, it could have caused a horrible accident. I could not accelerate enough to stay on the highway. That issue was fixed when we took the vehicle into the dealership to fix and should have been a recall as other cars where having the same issue. Hyundai should be held responsible for issues such as this that are affecting many other Hyundai Tucson drivers. Oil keeps depleting and the engine is burning through fast, also another concern and safety issue as that causes the engine to over heat and potentially cause a fire. A loud noise is coming from the vehicle, sounds like a helicopter it happened suddenly with no check engine light or warning. I'm concerned this car could catch fire, many Tucson's have had warning of catching fire. I don't park in our garage or even in the driveway for fear of that happening although they state ours is not supposed to be affected all these vehicle issues are telling me otherwise. Engine is now dead. This is unacceptable. Windows cannot be rolled down after multiple fixes that I paid for. Hyundai's poor production, manufacturing and quality control is unacceptable, please hold them responsible. Too much money has been spent on issues with no real results.

Failing transmission including inability to engage reverse and slipping gears while shifting.

I bought a used 2016 Hyundai Tucson locally. Had the car 3 days, & both rear window actuators had to be replaced. Had the car a week, oil pump/pan seal failed. Then the rear seal fail. Then the boot on the right cv joint failed. The aac started blowing hot on the passenger side, while cold on the driver side, but I don’t have dual controls for the temperature & it’s full. Bluetooth randomly connects/disconnects. Gas gauge is inaccurate says 40 miles left & then suddenly your light is on & it says you’ve 20. Repeatedly replaced my brake light bulbs/front turn signal bulbs, several times within a few months of each other, often on the same side. Having my phone plugged into the charging ports, the phone often overheats to the point of being too hot to touch. Even placed out of the sun’s rays, & shaded. Must pull front passenger door 2x externally before it will open. Rr passenger door you can pull all day/push from inside /outside, doesn’t matter, won’t open. The car is equipped with a cvt, which allows you to shift manually if needed. Then the transmission refused to shift automatically. No codes would show. Today car died on me in the middle of the road, while I was turning, check engine is on, & car refuses to start. I was almost hit by cross traffic from both directions. A few people drove around me, before two very nice young men pushed my car out of the middle of the road onto the shoulder of a county road, on a holiday weekend. If not for a good samaritan, I’d have been walking 6 miles home in the dark. I’m almost 50, & a woman, & diabetic. The car has plenty of oil & coolant. Tried putting the car in neutral, still won’t start. Air filter is clean. Battery is good. Says it has gas; 40 miles til empty. Car tries to turn over but won’t catch. Tachometer will barely register to the line above zero, & even giving it gas makes no difference. Have been told it is the timing & transmission. Dealer won’t honor extended warranty. Car has “just” passed Hyundai warranty.

I already had a recall scheduled 4 days before this accident but 2 days before the engine failure I heard a ticking in the engine , didn’t think much of it because the engine was still running ( 93k miles on the car) so I was going to tell the dealer the problem when I took it for the recall fix appointment but on the way home my car instantly went from 70-30 in the middle of the highway I had the car towed to the Hyundai dealer and they said rod had broke and said also something about the oil being dirty when I literally had the oil changed days before , but end result my 2nd owners warranty didn’t cover the vehicle even with rod failures being a recurring problem with my trim. They told me a new engine would be 13,500k while still owing 10k on the vechile has but me in a difficult situation.

Excessive oil consumption nm, replaced catalytic converter twice. Losing power again. 122450 miles. Trans mission slipping, not shifting into higher gear. Gas mpg down to 19mpg. Unsafe on highway, loses speed and revs too high.

The vehicle intermittently fails to accelerate without warning or notification. The throttle pedal goes to the floor without the engine stalling or rev'ing but also fails to propel the vehicle. This has occurred when crossing lanes of on-coming traffic placing the operator in an extremely dangerous situation. In addition, the vehicle also intermittently fails to go in reverse. These issues are most prevailant in warmer summer temperatures. Neither of these issues directly triggered a mil light. Mil lights did occur independent from the cited issues but would typically self clear. On one occasion I was able to get a scan of the vehicle with an active mil that yielded a p1921 gear 2 system motor thermal damage. Shortly after the scan, the code cleared and mil went off. The conditions were not able to be reproduced by the dealership. They were also not able to clearly diagnose what would cause the p1921 fault. Their recommendation was to replace the entire transmission. All of the issues experience closely align with a issues cited in a class action law suit despite the vehicle not having any open recalls or tsbs.
