general problems of the 2016 Hyundai Tucson - part 1

Driver side door lock actuator failure yesterday. 4/10/26 purchased this car 8/15/25 was not told there was a problem and recall.

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.

No check engine lights came on! the entire car caught fire and was engulfed in flames!!! driver could have been killed!.

The transmission began slipping and hesitating within days of purchase. The vehicle intermittently fails to accelerate when pressing the gas pedal, especially when pulling into traffic or crossing intersections. This creates a serious safety risk because the vehicle does not respond when needed, leaving me exposed to oncoming traffic. The issue is intermittent and does not always trigger warning lamps or fault codes. The problem has been reproduced multiple times by me while driving under normal conditions. The selling dealer performed only a brief test drive and stated they could not duplicate the issue, but the hesitation and failure?to?accelerate continue to occur. The vehicle has not yet been inspected by Hyundai, but the symptoms match known issues with the 2016 Tucson’s dual?clutch transmission and tcm logic. There were no warning lights prior to the failure, and the symptoms first appeared within the first week of ownership. The vehicle is available for inspection upon request.

Three window regulators have failed, leaving the windows completely useless. The first occurring in heavy rain and making it impossible to close. This is an issue reported countless times online.

Drove into a parking space, with the foot pressing on the brake pedal, the car suddenly and without warning rapidly accelerated uncontrolled causing the vehicle to accelerate past the end of the parking space causing property damage.

Oil consumption is uneven, unpredictable, and has been a problem for at least 30,000 miles and since 2020. The car has ~74k miles on it and I carry a case of oil in the trunk. A couple years ago our catalytic converter clogged (I suspect from burning oil) and we were stuck on the roadside. Dealer replaced the catalytic converter under the power train warranty, but has not addressed the oil beyond a few consumption tests. They say it's "within normal parameters" but last night at a rest stop I had to add oil again. I feel like they're trying to wait until the warranty is up and then tell me it's not their problem.

Part(s) affected: engine / engine control / stall / loss of power summary: my 2016 Hyundai Tucson (VIN: [xxx] ) has an active p1326 – knock sensor detection system (ksds) code, which indicates rod bearing wear and imminent engine failure. The vehicle experiences: •loss of power •inability to accelerate •engine hesitation •risk of stalling while driving these are serious safety risks. This issue is part of the Hyundai/kia engine defect settlement xxx), yet Hyundai refuses to provide towing or address the safety risk despite the p1326 code being a known precursor to engine seizure. The vehicle is currently unsafe to drive, and Hyundai customer care has refused to escalate my case according to settlement requirements. This is a safety hazard that can cause engine seizure and sudden loss of power while driving. Details: •Hyundai case #: xxx •engine settlement code p1326 confirmed •Hyundai refusing proper support •vehicle should not be driven NHTSA intervention is needed due to Hyundai’s failure to address a known safety defect. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I have had 3 window motors go out in the last 7 months.

The rear doors stopped opening. Could be a failed lock actuator or the lock is sticking. This is a safety hazard, especially when traveling with a child in the car.

The reason of this complain is due to excessive oil consumption which now damaged my catalytic converter against Hyundai motors America. The complained started 2021 where we noticed that the low oil engine light up after only 1500 miles from last oil change. We submitted the complained with dealer (carlsbad and escondido CA) and my car failed 3 consecutive oil consumption test and Hyundai performed an engine cleaning, claiming it was going to fix the problem. This happened when the vehicle was still under warranty. At the time they said that if this did not fix the problem, they were still going to fix the car since the issue happened under warranty. The engine cleaning did not fixed the problem, my car no longer has warranty and my catalytic converter fails and makes the vehicle inoperable in highway (engine ceases to accelerate) . We submitted a complain with Hyundai corporate and they denied fixing our car since the vehicle was no longer under warranty. I would like to ask for them to fix the engine and catalytic converter make the car operable again.

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.

Door latch - after a few attempts of trying to open my rear passenger door. The handle does not seem to function properly and I’ve seen that a lot of 2016s tuscon have this issue with their doors.

-power window failures of all 4 windows. -windows will not open and close which creates a safety issue in case of an accident that renders the doors inoperable and escape is needed via windows. Also, if the driver is pulled over, the car windows do not work which makes the driver have to open the door which puts both the driver and police officer at risk. -both a dealer service center and an independent service center has confirmed the problem. -component was inspected by both a dealer maintenance shop and an independent repair shop. -there were no warnings.

Acceleration issues especially after coming stop. When proceeding to accelerate you can push pedal multiple times before the car jerks into movement.

The rear doors cannot be opened from the inside or outside after the door is locked then unlocked. This is very dangerous for rear seat passengers. There are a lot of complaints online of this problem.

The window regulator for 3 of the 4 windows have failed, the first at approx. 80,000 miles, the second two at 113,000 miles. The windows were not being operated when the component failed and just randomly opened while driving and could not be closed via the switch. This caused distraction and difficulty driving as it was raining for the second incident. When observed, the plastic window regulators were degraded to the point that the plastic was a powder.

One of the back doors will not open. Lock is stuck on. This is very dangerous if need to get a child strapped in/ out!!!! I googled this and see it's been a problem for many years on this make/model. High fees from dealers per door for their manufacturing defect! easy fit for a husband who will pull the door apart to fix the issue! which mine is not!.

Excessive oil consumption which has then in turned caused my catalytic converter to go out.

Both rear doors actuators will not allow to open from inside or outside, the passenger will open from inside and the driver door intermittently is the same and I have to juggle the handle or smack above the handle to get it to open on driver side. The passenger is only opening from inside and have to smack above the handle or put pressure to door to have the actuator release. . . . Both rear doors do not open at all. This is a safety egress issue. I have minor children and they cannot get out of the vehicle and if an emergency, the first responders cannot get into it.

What component or system failed or malfunctioned, and is it available for inspection upon request? the airbag system, brake system, and hvac system (air conditioning and heating) appear to have malfunctioned. A dealer confirmed that the hvac system is defective, identifying a broken evaporator assembly and a faulty temperature door actuator. The vehicle is available for inspection upon request. How was your safety or the safety of others put at risk? the airbag safety light raises concerns about whether the airbags will deploy during an accident. The brake light error creates uncertainty about the reliability of the brake system. Additionally, the defective hvac system is a significant safety hazard. The heater’s failure prevents the windshield from defogging, impairing visibility, particularly in cold or wet weather. This poses a serious risk while driving, especially in freezing temperatures. Has the problem been reproduced or confirmed by a dealer or independent service center? yes, the hvac system defect has been confirmed by a dealer, who provided images and recommended replacing the evaporator assembly and temperature door actuator. Independent mechanics have also observed the airbag and brake light errors but were unable to identify the underlying causes. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? the vehicle has been inspected by independent mechanics and one dealership but has not been evaluated by the manufacturer, police, or insurance representatives. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? the airbag safety light and brake light errors have been present since I acquired the vehicle. The hvac system began failing intermittently shortly thereafter, with the issue worsening over time. These unresolved issues continue to jeopardize the safety and reliability of the vehicle.

The driver's side rear door cannot be opened from either inside or outside. In researching the problem, I found evidence that the issue is commonly reported with the model 2016 Hyundai Tucson, which I own. Many other owners have reported that their vehicles have experienced the same issue. Mechanics have also expressed curiosity about why there hasn't been a factory recall. The problem is a design issue in some model years, including the 2016 model year. Inability to access the back seats from the driver's side is an obvious safety concern.

3 of my window motors do not work and my windows now will not roll up or down.

This is the 2nd window regulator that I’m aware of this car is failing. 3 months ago before buying the car from the dealer they replace the rear passenger side regulator because the window won’t roll down or up. Now 2 weeks ago the front passenger side window stop working and I’m afraid that is the same situation as so many people compliant about this issue on forums and videos online. Also I used to have a 2010 Hyundai Tucson and have a problem with the rear passenger door not opening because the latch mechanism and the actuator. Now this 2016 Hyundai Tucson under this VIN number is experiencing the same problem due to a faulty design and cheap plastic products. This car has only over 61000 and can’t believe it have this many issues in the short amount of time. Definitely Hyundai needs to make a recall campaign for this components considering they’re key elements to an egress means of the car on emergency situation. Please help us so many owners to get a response for these issues. Thank you very much.

Right front window motor runs but window does not go up or down.

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

The teeth within a spool in the window regulator easily strip out leaving the window unable to be opened or closed. This has happened on three out of four windows on my vehicle.

Left rear door lock will not release when exterior or interior latch handle is pulled to open door.

Left driver side window conked out, does not go up or down.

The window regular failed is to weak don't last long have replaced all 4 and replacing the back one again.

Driver side door window stopped working. Not able to close or operate window. Hyundai dealer diagnostic found window regulator inoperable/needs replacement. Two (2) local Hyundai dealers have ordered the regulator and are still waiting for part. Dealer one not able to get regulator after 18 days; dealer two hoping part will be in after 10 days of ordering.

I went to roll up my window and I could hear it trying to go up but the window stayed in place. With my window stuck down, there is the risk of things flying in/out of my car while driving, and in the event of rain, my car would then become damaged if water got inside. Also, with a window stuck down, anyone can get into my car. This first occurred to my front passenger window on September 8, and just happened to my drivers window today, November 1. Both times occurred when my car was not moving. The passenger window was fixed in October and was diagnosed with the regulator and motor needing to be replaced.

I had my top engine block (not sure why not a full engine replacement) replaced under warranty June 2023. Shortly after the fix my ac unit stopped working. Once I got my ac unit fixed, about 1. 5 months after my engine was not performing. My car would not turn over and when it did, it was in limp mode and would not run properly. I had it towed to dealership who could not find the issue until after they took out of the bay and went to move it, it wouldn't start. They replaced the crankshaft positioning sensor and it wasn't covered under the extended warranty. The top engine block only has 10k warranty which is fast approaching. Took car home and when accelerated past 60 car shakes and when I brake car shakes. Now car cabin smells of gas. All cars with km are having multiple issues. Dealership not calling back regarding gas issue and has not responded to if they touched my tires. Local mechanic said all my wheels were unbalanced.

The car door handles are failing to work properly. Initially (June 2024), the passenger side front door required the handle to be pumped twice before it would open. The door would open correctly from the inside only. That problem was corrected. Now (Aug 2024), the driver side rear door handle has failed and the door cannot be opened from the outside or inside. The precise nature of that issue will be determined tomorrow. In June, I was told by the service advisor at jenkins Hyundai of ocala [florida] that Hyundai is aware of an issue with the functioning of door handles (I. E. , the actuator) and has extended the warranty from five to ten years for this issue. I my judgment, this is a major safety issue if a door cannot be opened.

At certain times my car doesn’t want to start. Like when there were carburetors in cars way back in the day, I literally have to pump the gas to make it start. And then once it does, it’s very hesitant to go on the road like it has no power. And then another time my car totally just shut down in the middle of traffic and would barely go, like it had no speed ability. This happens often my car is not under warranty. And it is not included in the recall with some kind of fuel pump situation. I had a mechanic look at it. He seems to think it’s something to do with the fuel pump. But unfortunately, I cannot afford the cost of repairing that, and he didn’t seem quite certain as well.
