There are four safety concerns I have with the 2016 Hyundai Tuscon: 1.) The Check Oil light failed to illuminate indicating the need for more oil. 2.) The excessive oil consumption may have caused my catalytic converter to misfire and melt. 3.) The Check Engine light failed to illuminate when my catalytic converter misfired and melted. 4.) The Knock Sensor (if it is bad), which is installed on my vehicle, could fail and not warn me about any engine problems. On 7/3/23, my vehicle was having a difficult time accelerating up a mountain. My brother and I also heard a rattling noise, so my brother drove to a safe place. I had my vehicle towed to a local auto service garage, where I was told the catalytic converter melted due to misfiring and that I needed to replace it. On 7/5/23, I had my vehicle towed to the closest Hyundai Dealership, where they confirmed that the vehicle's catalytic converter was melted due to misfiring. After researching the causes catalytic converters misfiring, I read several complaints about the said vehicle's oil consumption and poor acceleration. I suspect there might be a connection to the catalytic converter misfiring and melting. Incidentally, I have had two other incidents where my vehicle lacked acceleration and started shaking. One occurred on 12/28/22, while I was entering an intersection. The other happened on 4/1/23, while I was attempting to pass another vehicle. All three incidents could've ended tragically. The Check Engine light did illuminate during two of the incidents, but not the incident that occurred on 7/3/23. Additionally, the catalytic converter was previously tested on 12/31/22 and it didn't have any bad codes. Sparkplugs were also replaced on 12/31/22, and a 3-Step Fuel System Cleaning was done on 6/12/23. The Check Oil light only illuminated once since I have owned the vehicle, but failed to illuminate when my oil was getting low in between oil changes. My SUV is still in service waiting for a Catalytic Converter.

The engine of my car is consuming several quarts of oil between oil changes. I have read that this is a common problem with some models of Hyundia vehicles. I have also read that this defect has led to engine failures and possibly fires.

Engine is consuming oil and we are waiting for it to totally fail. We have a long list of things. These are notes from the end of the process when we gave up. I responded after the fourth consumption test on 11/28/2022 asking for them to re-open my case and have not heard from them so I called on 12/9/2022 to speak to my case manager. We started this journey with 118,000 miles and now we have close to 164,000. Went from 1qt every 1000 miles to 2qt’s every 1000 miles. Had to get another case manager to leave a message for my case manager to call me back. I don’t even know if they re opened my case. Hyundai has refused to admit the have a large issue with their GDI motors. They should not be consuming oil as much as they are. Only Theta motors are being covered in Non Turbo cars. This is my second vehicle currently owned with a gamma turbo motor. This one is waiting to fail and the other one has failed.

Both of my back doors will not open from the inside or out. Thanks to youtube I watched videos on how to open doors from the inside I had to pull latch and then stick screwdriver in there to lift cable up up door would open. This is very dangerous for doors to not open up, taking time to use a screwdriver to open them up is ridiculous, according to youtube the cable was made too short. I called the manufacturer and they gave me a price of 700-1200.00 to fix. I really think this should be a recall. If someone in back needs to get out in emergency situation then they are stuck.

I purchased a 2016 Hyundai Tuscon new in April 2017. From the beginning I felt there were issues with this vehicle but was also told that everything was fine. In 2019 the car stopped getting power and I was unable to go over 60mph on the highway. Hyundai said it had run out of oil but I had always gotten my oil changes from Hyundai directly. Also- no alert that my oil was low every came on. They replaced the engine or parts of it but I was still required to pay about $3,000 at the time. In Jan. of this year I realized that the car was not running as it should. Hyundai in Milford, CT had me pay for the oil change and also pay for the oil consumption test. On Feb. 20th I was approved for a new engine. I have been given multiple dates of when I my car would be repaired with the last date being May 17, 2023. I have not heard anything from Hyundai. I submitted a complaint with Hyundai corporate (21515374) and they have done nothing except tell me that they are still waiting for an answer as well. I am afraid to drive my vehicle long distances and do not know what kind of service I should get while waiting for a new engine. I am now carrying oil around in my vehicle but think that this is horrible wrong. I am still paying almost $600 a month for a vehicle that I am afraid to drive and I have not received any answers from anyone regarding when my repairs will be done or even getting a rental while I wait. After reading hundreds of other complaints this seems to be an issue with Hyundai and everyone says the same thing about the oil warning light not coming on at all. I purchased my vehicle from Hyundai in Milford, CT.

excessive oil consumption. it has been confirmed by valvoline instant oil change center. after an oil change, round 600 miles the oil is to be checked and topped off completely because the reservoir is bone dry. can not make it a complete 3,000 miles until the next oil change. the oil has to be topped off at least 2-3 times until the next oil change. there are no warning lamps, messages, or other symptoms to notify of the problem. it has been inspected by hyundai dealership, whom at someone point replaced the turbo in the limited 1.6L. also, the windshield wiper reservoir decided to stop working. I have to wait until it rains or go through a car wash to clean my windshield. all hoses have been checked and there are no leaks or disconnection of the hose. the windshield wiper fluid will not come out and remains completely full.

I was driving down the highway and I saw my usb cord smoking, I immediately threw it out the window to avoid a fire and pulled over on the highway. My heart was racing and then I called my mom. She thought it was the AC filter that needed to be changed. A few months later in October, the engine failed. A dealership fixed the engine, but it's still consuming a lot oil. I called Hyundai about the engine issues but I forgot about the smoke I saw. They closed the case on the engine, because they claimed I had no warranty. I have no warranty, because Fairfax Hyundai told me they no longer accept car shield. Hyundai closed my case last month and reopened it on 6/30, because of the smoke. I originally bought the car from Waldorf Honda, in Maryland. Dozens of issues have been reported with this vehicle. On 6/30 I realized that the two back doors also stopped opening from the inside and outside.

Complete Engine failure under 100k miles. Electrical issues with toggle switches

NHTSA ODI 11529422

Door latch suddenly stopped working, making it impossible to open the door from either inside or outside the vehicle. Had this occurred in an emergency situation passengers could have been trapped inside. Hyundai is aware of this defect and has issued a Technical Service Bulletin and purportedly extended the warranty but there is a shortage of parts to make repairs and so they cannot effectively honor that warranty or make needed repairs. NHTSA should require a recall on this problem to inform owners of this potential hazard and force Hyundai to put more resources into correcting the defective latches and possibly avoid unnecessary loss of life.

Similar to other owners my car has been burning oil at a higher-than-normal rate. Because of this, there has been a carbon build-up causing my engine to start misfiring and stop working while driving on the interstate.

Was driving on the highway and my car wouldn't go above 45mph, then check engine light and oil pressure lights came on. Pulled over on the shoulder and checked the oil and it was low oil by about 2 quarts. I checked the oil about 3 weeks prior and had no issues with oil loss and had no lights ever come on the dash prior. Had to get towed home because the car was sputtering and would accelerate. The car is inoperable now and needs engine repair.

NHTSA ODI 11528336

My car was having issues with the engine making a rattling sound and having difficulty accelerating. About a week after the symptoms came up, my car died on the side of the road. I am so lucky I was in a neighborhood and not on the freeway. No lights came on at all until 10-20 seconds before it died. I was able to get my car to the dealership and was told I'd need a new engine. Although I bought it used, I've only had this car for four months. I'm hoping Hyundai places the 2016 Tucson under recall as many others seems to have similar issues.
