The incident occurred to me while I was 7 hours from home. I was stopped at a stop sign on a curve in the road. When clear, I accelerated and as I turned and merged into the road, the car started making a loud knocking noise and lost power as I was going up hill. Right before I lost all power, the oil light flashed briefly and the engine light came on. I restarted the car and again heard a loud knocking noise but was able to pull over to the side of the road. As soon as I slowed and stopped it died again. I ended up getting towed to the Hyundai dealer. The next day I called and they let me know I had "thrown a rod and had bearing damage". they said I need a new engine and quoted me $12,800. I have provided all service records to them which prove that I have maintained the vehicle with oil changes and major services done at Hyundai as well as valvoline. Their initial offer to me was they would cover 50% of the repair. My service advisor countered them with 90% and their final offer was to cover 60% and no rental - even being 7 hours from home. Before this incident occurred, I have not been able to open my rear passenger door in months due to needing a new actuator. I also let them know that I believed there was electrical issues because my tail light was always going out even after being replaced. I was dismissed and told that I had a faulty bulb. Same day after getting replaced, I was again getting that "check brake light" message. I believe there is a recall that I do not qualify for for this issue. After much research, I have found engine failure is a major problem with Hyundai with many people on their 2nd and 3rd engines, including 2 people in my own family. I am extremely disappointed in the way Hyundai is handling this situation and I will no longer be a Hyundai customer. Please let me know if I can provide any further information. Thank you!

The rear back doors will not open from the outside, creating a safety issue for the children/people sitting in the back seat. Hyundai refuses to take responsibility for this iissue and wants to charge over $1,000 with labor to fix it. I purchased the car certified preowned in 2018.

I bought a brand new 2016 Tucson from the dealership. After two years the front driver and passenger door handles didn't work properly. I have to pull the handles 4-5 times before the door will open. I took it to the dealer and was given an astronomical price to fix it. I am the only person who drives my car. There should be no reason why these handles are malfunctioning like this. Then last month the back door on the drivers side will not open at all. This is ridiculous! this is dangerous. If I had someone in the back seat and an emergency happens they would not be able to get out. I can't be the only customer having this issue. Is there something you can do about this" this car was paid in full. I've already paid enough for this car. I should not have to pay for malfunctioning dangerous door handles. What can I do"

In my 2016 Hyundai tuscon the rear passenger door will not open from the inside or outside. It locks and unlocks via keyless entry, indoor lock/unlock button and key fob unlock/lock button, however the door does not physically open. It spontaneous occurred when trying to get into my car. This is a huge safely concern if someone needed to leave my car in an emergency situation. Upon research this appears to be a chronic problem with a massive amount of 2016 models, some having issues with multiple doors. It appears to be an issue with the lock actuator that was installed is most of the 2016-2017 tuscons. Hyundai is not willing to acknowledgement that it is a safety concern that needs to be a recall on all of these models.

Once locked and then unlocked, the rear passenger door is unable to be opened from the inside or the outside of the car. This is due to failing door lock actuator. This prevents passengers from exiting the car and is a major safety concern. The same door lock actuator is on all doors and is a known issues with Hyundai.

- Houston, TX, USA

The pasanger side door and rear left door will not open from the inside. The car is stationary. We have had the car for only 6 months bought used 42,305 miles on it.

While a passenger was attempting to exit from the driver side rear of the vehicle, the latch was non-operational and they were unable to exit using the internal latch. Child safety mechanism was not engaged. The exterior latch also didn't function. The locking mechanism is in the unlocked position. This made exiting from or retrieving a child almost impossible during any emergency situation. The door latch needed to be replaced. After checking owners' forums, it seems that this is a common dangerous failure for this type of vehicle.

The driver side rear door will not open at all, from the inside or outside. This happened outside of the 60,000 mile warranty period, so Hyundai refused to voluntarily fix the issue. The latching mechanism should not be worn down so quickly, within 4 years of manufacture. This is a serious safety concern, as potentially all car doors could fail, leaving passengers stuck inside in the event of an emergency. I have emailed and called Hyundai usa and notified them of the issue, but have yet to receive a reply.

Door lock actuator on 3 of 4 doors has failed. This means that the door cannot open from inside our outside of the vehicle. The vehicle was stationary, I parked and when I returned, I could not open the doors (in all 3 instances). Front passenger and both rear doors. Rear doors failed within a week of each other and all three instances of failure have occurred within a year (front in January, rear in October). I contacted Hyundai about the problem when it occurred with the rear doors, concerned that this could be dangerous (I.e. people trapped in cars in the event of an emergency). The Hyundai representative I talked with agreed that it was a huge safety risk/issue, but unfortunately they could do nothing about it without the direction of the NHTSA (such as a recall of the door lock actuator).

Rear passage side door will bot open from inside or the out. Called Hyundai nothing was done.

- Cato, NY, USA

The rear passenger door will not unlock regardless of how or when it is tried. The dealer says the door actuator is faulty. No one can enter or exit the vehicle from that side, even in an emergency. This problem appears in hundreds of posts about this model of Hyundai tuscon. Only a dealer can repair and replace the problem at a cost of $1600. No recall has been issued for this.

Mileage is at 63K and my front passenger and rear driver side door will not open. The rear passenger will not open from inside or outside. The front passenger will take 5 tries to open and will open.

The rear driver side door will not open from the inside or outside of the car. The lock does click back and forth but the door remains stuck. This is a major safety issue for anyone traveling in the backseat of the car as they would be trapped in the car and unable to exit from that side of the vehicle.

A rear door lock is 'frozen" in a locked position. It rejects physical and electronic attempts to open. It remains when engine is off or on. It is not locked by child protection. It clearly is a danger to occupants in case of an accident fire. A web search for Hyundai Tucson 2016 (and some similar) door locks shows this is not uncommon. Neither the door nor lock nor handle have been damaged. There is no company recall or offer for dealers to repair.

The rear driver's side door latch failed suddenly and without warning on my daughter's 2016 Hyundai Tucson. The door could not be opened from the inside or outside of the vehicle. Not being able to open the car door could have led to so many health and safety issues depending on the situation. Please imagine if the driver's door failed during a vehicle fire, a submerged situation, a car crash, etc. Think of the possibilities of your child driver being trapped in the car during a situation like I just mentioned. As you can expect, I'm very disappointed in the defect and I'm shocked there is no recall or free repair available for this serious safety issue. I've purchased this vehicle based on the excellent ratings of quality and safety. From what I understand, each of the door latches could subsequently fail as well as the new latch recently installed. This is unacceptable. I'm nearly 60 years old and have owned over a dozen cars in my life. This is the very first failed door latch I've had and have ever heard of.

Rear driver door will not unlock either from the inside or the outside. You can hear the remaining doors lock and unlock but not the rear driver. I Transport my grand children and this is a safety issue. The cars has 16K miles on it and is still under warranty. Dealer said it will take about 1 to 2 weeks to get the part in. I was told that this has happened to alot of the Hyundai Tucsons.

Rear passenger doors won't open from inside or outside door handles. This started intermittently then ultimately trapped passengers in the rear seats of the vehicle. Nothing worked to release the doors, causing passengers to have crawl through front seats to exit the vehicle. Investigating of any recalls we found that this is wide spread over several years, and charges range from $400 to $2K. When clearly this is defective components or design, used in and for locking system, fair expectation that occupants can exit the vehicle in the case of an emergency. Hyundai service considers this a malfunctioning part and not covered by warranty or by age of the vehicle. The doors locking actuators are malfunctioning there is no option to manually open the doors, again causing a person to be trapped in the vehicle. People are reporting from 1 door to all 4 doors failing to open. Our car the rear doors do not open. Hyundai should take responsibility to fix this defective part/design and not at the car owners expense.

After parking the car, I went around to the rear passenger side to get one of my children out of the carseat when the door wouldn't open. Child locks were not engaged but the door wouldn't open from the inside or outside of the car. After using the keyless entry and inside driver side switches to unlock the car numerous times, the door wouldn't open. The other 3 doors were unlocking and locking just fine. This is a huge safety concern as my 8 month old was located in the rear passenger seat.

My doors have been not being able to open from the inside or out. This is the 2nd time this has happened and they say it's because the door latch is bad. This is a total safety issue, because if I were to get into an accident and my only way out was the door I would be locked in and potentially die. The fact this has been an issue for people for over a year and still not a recall and for it to happen to me twice is ridiculous. My dad is a first responder and says that this isn't a recall is unacceptable. And the fact that the only way it will be a recall is for someone to die in the accident and for them to sue Hyundai to be a recall is ridiculous. Please consider the door latch issue to be a recall you can see all the other complaints online by typing in google. My door will randomly just stop opening one day once you close and you cannot open it from the inside or the outside. This has now happened on both rear doors.

- Solon, IA, USA

The door lock actuator is failing and doesn't always function resulting in the door being un-openable. When actuated, the door unlock button on the key fob sounds as if the lock is opened, but when I pull on the handle, the door will not open. After multiple attempts at pulling on the handle, the door will open. This is impacting my left passenger door. After looking on the internet, this appears to be a widespread issue with this vehicle.
