2016 Hyundai Tucson Front Right Passenger door latch does not allow door to be opened from the outside. No warning. Research shows this as a definite safety issue on several Hyundai models and has been for years but see no recall. Doors can be impacted from both inside and outside with no warning. Crawling over the seats from the inside to open the door or being trapped in vehicle are a real possibility. I have a scheduled appointment but understand it could be a costly repair that should be considered a replaceable manufacturer’s defects AND A SAFETY HAZARD!!!! Car only has 66,000 miles.

Rear liftgate did not latch on three occasions this winter when temperatures were below freezing down to -4 degrees. The liftgate would lower but not latch properly. Dash would indicate that lift gate was not latched. Attempts to latch manually were unable. During the drive home, the lift gate would moved freely. In order to not risk spilling cargo, we moved everything out of the trunk area.

Rear door on the driver's side will not open from the outside or the inside. This is a known problem but there is no recall. I called my local dealership and they won't guarantee that this is under warranty, and they won't give me an appointment for 6 weeks. Hyundai and it's Service Reps are clearly not concerned with their customers.

Has been happening for the last few years, but recently got worse: very difficult to get car to move forward from a dead stop, car would shudder like it was going to stall out. Took car to a Hyundai dealership on October 4, 2022, who were able to replicate the problem. Issue was for transmission to be replaced under drivetrain warranty. Once transmission had been replaced, there were no more problems with moving into first gear from a stop.

Unable to roll passenger window down using the power control on the driver's door. Took it to a Hyundai dealership for diagnosis and repair. It cost $506.67 to fix, driver front main window switch was replaced.

Driver's side passenger door sounds like it is unlocking when I use the key fob or the interior power lock on the driver's door, but the passenger door can only be opened if I reach from the driver's seat across the center console to manually open the door using the handle. No way to open the door from the outside using the outer handle, even if it looks like the lock is fully open from the inside. No dashboard warning symbols. This appears to be the subject of a technical service bulletin, Hyundai TSB 21-BD-006H, so I will be contacting my local Hyundai dealer next week to set up an appointment for diagnostics and repair, hopefully covered under the extended warranty described in the TSB.

The car started to shake while driving on the highway and it lost power causing it to slow down dramatically, the car driving behind almost hit my car. The issue started with the engine losing motor oil, the dealership said there were no oil leaks and maybe the head gasket needed to be replaced. After the incident one the highway, the car was towed to the closes dealership for service, after diagnosing it was determine that cylinders 1 and 2 are miss-firing and the piston were stuck making it loose compression. Dealer said that they have seen this before, but my VIN does not take part of a recall campaign with other cars having the same symptoms.

When driving the vehicle is slow to accelerate hence posing a risk of being rear ended. It makes loud noises when going down hill and it tends to slow down even when you're foot is on the gas pedal. This is a concern for me since I have a small child that rides with me to and from school. The passenger a d driver doors jam on multiple occasions. The non acceleration especially when merging on highways or after traffic light stops is very dangerous since the person behind has no idea what's happening. When you stop the vehicle on a hill at a traffic stop and it's time to go on green the vehicle tends to pull back abit before accelerating, making the person behind wary of being hit. The loud noises made by the vehicle especially driving down a hill are just annoying, if you break to go slower, the noise is even louder. The lack of acceleration and jamming that the vehicle has me very worried for my safety and that of my young child, since we use the vehicle everyday for school drop offs and pickups and work. I am wary of driving it for any other reason that that which isn't fair because I pay for the car each month!!

The automatic windows broke in all 4 windows and I am unable to roll down my windows in the case of an emergency. The dealer confirmed this is an issue. This is a known issue on the 2016 Tucson.

Earlier last year (a few months after purchase), I took my vehicle in for a routine oil change and was informed there was barely any oil in the vehicle. The prior oil change occurred less than 3500 miles before, plus there were no warning lights. After this occurred a second time (only 2600 miles between changes), the dealership recommended a series of oil consumption tests. I was informed the vehicle failed and the information would be provided to corporate. HMA (corporate) declined to address the issue as I was the 2nd owner and purchased the vehicle outside of warranty mileage, 60k. Vehicle was purchased with under 61k miles. With a recent oil change, I was informed that it is a matter of time before my engine fails. I do not know when this will occur and the vehicle gives me NO warning that the oil is low.

I heard a knocking sound on the morning on 1/6/22, immediately took it to a Hyundai (Capital Hyundai) dealership who informed me it was a known issue they are having to rebuild tons of engines. They would not be able to even look at my car for a few weeks, but I needed to leave it because the engine could seize at any moment. While thy offer loaner vehicles, I wasn't eligible because of the time before they even could look at my car. After paying to rentals out of pocket for two weeks, I received a call today to tell me that because I'm not the original owner (I'm the 2nd owner) they are not honoring the rebuild and I could pay them $8300 plus and additional $2500 to repair their known issue that their Service manager acknowledged. Not to mention Hyundai recent class action lawsuit in 2021. If that wasn't enough, I just received a call from Hyundai corporate office to say sorry if you were the original owner, we could help. I asked the representative if it was a company practice to use that as a deterrent from acknowledging their design/mechanical fault to save cost and she said I'll make a note of that. Is there anything I can do? My vehicle has been serviced every 3000 miles and I have my records. Considering contacting my attorney as well

Engine failure while going 70mph on the highway - huge safety issue! Spark plugs totally covered in oil and the engine has major known oil consumption issues. Also 3 of our 4 door actuators broke - huge safety issues as we have kids in our back seats in car seats. This form doesn't have enough room for the letter I have composed about the specifics of the situations. Hyundai has known issues with their engines and some are under recall. We were told ours is not under recall and they will not fix it or help at all to fix it even though many of their engines have/had the same issues as ours and those engines are under recall.

Put the car in Drive and car failed to move with motor revving. Car finally moved about 20 mph max. Attempted to shift the car in and out of gear as well as shut it off and problem still existed. Got it home and made arrangements for tow truck to haul to dealer. In moving it the next day to prepare for tow truck the transmission worked normally and drove it to the dealer. Dealer could not duplicate the problem so they said there hands were essentially tied. Did and internet search on 2016 Tuscon DCT transmission problems and found the problem is very common. Hyundai attempted to address it with a computer update which this car has had. Many people have been placed in very dangerous situations with this problem. No warning lights were displayed despite the car being essentially undriveable . This is a known safety issue which should be addressed by the manufacturer. A car that suddenly becomes undriveable in traffic or leaving you stranded in the middle of nowhere is definitely a safety issue.

The manufacturer then referred him to another dealer for an oil consumption test. Once at the dealer, the vehicle did not pass the oil consumption test.

While driving on the highway, traveling about 70mph, check engine light comes on and car looses power. No previous warning signals, smells, smoke, exhaust, drive behavior. Dealership said the piston ring on cylinder 2 is almost completely broken and the repair is a full engine replacement. Dealership has quoted me $18,000 for the repair, which is what I paid when I bought it used in 2019. At this point, I'm dealing with catastrophic engine failure and Hyundai won't do anything about their faulty product and is seeking to take full advantage. Insurance won't cover it and the car is out of warranty. I have never owned a worse car than this Hyundai. It's the final straw in a list of issues I've had with the car since I purchased it.

Transmission is defective. Car wanted to override my foot braking at lights & stop signs. The potential for the car to force me into traffic or a vehicle or wall in front of me made for a hazardous situation. Coconut Creek Hyundai Service Department (via [XXX]) stated the transmission had an internal failure & must be replaced. I do not know if the manufacturer, police, insurance representatives or others have inspected the transmission -- I am only aware that Coconut Creek Hyundai Service Department has inspected it. There were no warning lamps, messages, or other symptoms of the problem prior to the failure. It first appeared in early November 2022. I tried to make an appointment & could not so I took it to the dealership on November 8, 2022. I bought this car from Coconut Creel Hyundai as Certified Used on September 6, 2019. Coconut Creek Hyundai in Coconut Creek, FL 33073 has had my car since Nov. 8, 2022. They replaced the defective transmission with another defective transmission the 1st week of December. I have had to pay out of my pocket for a rental car. Today is December 14, 2022. The least Hyundai can do is provide a car for me. The dealership has not done so. Hyundai USA (Case #: [XXX]) has not. My warranty only covers 10 days at $35.00 per day. A rental that I can use cost $40/day. I waited until December 1, 2022 to rent hoping my car would be fixed within a reasonable amount of time. My 10 days & my patience with this corporate pass the buck attitude has ended. I have no idea if the dealership got another new transmission or if they have installed it. This dealership has major communication issues. HyundaiUSA has lost a 3-time Hyundai owner. I just hung up with supervisor [XXX] from HyundaiUSA & she cannot authorize payment for a rental car nor speak to my case manager ([XXX]) about rental car payment/reimbursement. I have been without my car since Nov. 8, 2022. I stopped using my car Nov. 3, 2022 because it was too dangerous to do so.
