The wastegate on the turbo malfunctioned, causing the turbo to need a complete replacement. Prior to fixing the issue, the vehicle would not accelerate correctly. The vehicle was not capable of reaching highway speeds quickly. The engine warning light was on (low turbo boost) but it only came on once acceleration was affected. The mechanic shop has a photo of the failed wastegate and the bottom portion where it connects was completely broken off.

Car stalled with no warning/check engine lights. There is still no fix. I don-??t want to keep paying on a car that is going to cause an accident while driving! I-??m lucky I wasn-??t going at high speeds when it stalled. My children and myself could have died! No one ever called to do any testing but they knew about the recall in July when they told me about it. I-??m very concerned that this will happen again even if they do -??fix it-?? this is a problem on multiple vehicles from Kia and Hyundai.

My 2017 Hyundai Tucson 1.6 L Turbo has been stalling, bumping, knocking, and using copious amounts of oil for the past several months. I checked the oil level and discovered that the engine had nearly completely run out of oil. I immediately brought the vehicle to my local dealership and they seemed completely mystified by the problem. They advised that I run the car through an expensive oil consumption diagnostic test. I did not, opting instead to do some research myself. Lo and behold, I quickly discovered that both Hyundai corporate and local franchisees have been well aware of the issue for some time. It involves connecting rod bearing failure. A class action suit was filed over the issue in California federal court and Hyundai corporate agreed to fix the problem through a voluntary settlement. Unfortunately, that settlement only covered Tucson models before and after my model year. If you wish to learn more about this issue, it has its own website (HyundaiThetaEngine Settlement.com). To further complicate matters, Hyundai corporate has in the interim issued a voluntary recall for my model year 2017. Unfortunately, it appears my specific model may be excluded. I can be reached at [XXX] or at [XXX]. Please get back to me ASAP, preferably before my car completely runs out of oil and the engine explodes. Thank you for your time.

My car was towed to the dealership because the oil light came on. There was no oil in the vehicle, even though I adhered to the oil change schedule recommended by Hyundai. I then had two series of oil consumption tests completed and it was determined that my car was burning approximately 1 quart to 1.5 quarts of oil every 1,000 miles. Hyundai advised me on several occasions that this was normal consumption and even advised this on today's date, even though there is an active recall for this issue.

Hi how are you. I recieved a email about the recall for engine that stalls out. I believe you doing this because of the 100 emails i sent complaining about it and the 20 times i took my suv to the shop for it and they could not fix it. I contacted the dealership and they told me there is no recall and they cant help me. When i take off my SUV will stall in middle of intersection which they though it was the Duel Clutch and now you figured it was the engine. How can we get this fixed or add my VIN to the recall list. Recall ID # is 21V727. Thanks

Stopped at a traffic light or corner waiting to turn, when I push the gas peddle to accelerate, the car will begin to accelerate and then hesitate and stop. When this has happened, I've pushed my foot pedal down to the floor. The vehicle jerks forward with a 20 second delay. Additionally, if I am in slow moving traffic and traffic begins to speed up, my car will hesitate to go forward when I try to accelerate. This is safety issue,

Hello. I recently took my car to the authorized mechanic and had them check on an issue I am experiencing. For some reason, my car frequently hesitates when I go from a complete stop/slow roll to accelerate. For example, if I am stopped waiting to turn, often when I push the gas to accelerate, the car will begin to accelerate and then basically stop. When this has happened, I've pushed my foot down to the floor on the pedal before to make it go and it refused to go for about 20 or so seconds. Additionally, if I am in slow moving traffic and traffic begins to speed up, my car will hesitate to go forward when I try to accelerate. This is a huge safety concern. The mechanic was not able to replicate this issue, but it happens every day or every other day. It makes me scared to drive because it's almost caused accidents. I read I'm not the only one with this issue and honestly, it's a miracle no one has died yet as a result of this faulty issue.

My car was purchased brand new in November of 2017. It has 71k mikes on it and has been regularly maintained. I began To notice around 50k miles that the oil was brining at an accelerated amount. My car required oil before the designated 5k miles and it would begin -??clicking-?? which alerted me to this issue. September 17, 2021 I was Driving and my vehicle failed to accelerate and began making noises that resembled the oil issue. My car had a full synthetic oil change less than 3k miles ago and by the time I pulled Into my driveway the car stalled. Checked oil and it was low. Added 3 quarts of oil on 9/17/21 and left it to sit. 9/18/21 car started and was driven to car wash and was sitting idle for approximately 45 minutes and on drive home, stalled and had to have oil added again. No leaks were present at anytime and no smoke. Went to dealership where I purchased vehicle and was told they would need to do oil consumption test but that would require me driving it 1k miles up to three times. I explained that my vehicle was breaking down and I was Fearful to drive it. In fact I bought A new car on 9/18/21 and have to get this car fixed to sell. Dealership said this is a known problem and no other way to assess than for me to drive the car the 1k miles and test it. It is still under warranty. I was also informed of an ABS issue that they can fix at same time. While all of these issues are going on, no check engine light or any other diagnostic symbol appears. This makes it hard to even catch before getting to the point of stalled engine. This can be a danger to myself, family and others when car stalls on major highway.

My vehicle had just over 69,000 miles and the engine seized while I was driving. The engine had to be replaced. This notification is a FYI, since Hyundai (from my understanding) is having motor problems in other models.

Dangerous acceleration issues... my car hesitates for almost 10 seconds when accelerating from a complete stop, at a stop light or turning into oncoming traffic and sometimes changing lanes at low speeds. This has caused near accidents on several occasions. I have even experienced the vehicle completely shutting off while idling and moving at low speeds in heavy traffic or going thru a drive thru restaurant. The Drive Clute Transmission (DCT) description that came with my vehicle when I purchased it mentioned "a direct driving feeling which may fee different"... "more noticeable when starting from a stop or low vehicle speed"... what it failed to mention is that the car would delay or hesitate for near 10 seconds then leap forward or even completely shut off putting my safety and the safety of other drivers at risk for injury or worse fatality. The DCT is a major safety concern and a common reported issue. Why aren'tyou doing anything to help consumers" I'm tired of dealership mechanics stating there's nothing they can do to fix the issue because Hyundai hasn't issued any recalls. The 2016 model had a recall for this same issue. I am a single mother and veteran and I need to have a safe running vehicle. Hyundai boasts the best warranty available and I even purchased an extended at the time of purchase so why can't Hyundai/dealership do anything to fix this" This has been an occasional issue since around 30k miles but had gotten more frequent and worse. I first made an appointment for the issue in 12/5/2020 at about 51k miles.

Engine failure at highway speed. Put family/children and myself at risk on an interstate when engine failed with no warning no CEL..after previously making complaints to Hyundai dealership for multiple engine problems burning excessive oil, excessive back pressure, oil leaks..dealer assured us no issues even after informing them we would be driving the vehicle on an extended trip. Left us stranded 5 hours from home..

We bought our 2017 Tucson with about 40000 miles in 2019. We have had some issues that are to be covered by the warranty. The last was the engine going. I was extremely religious about regular maintenance and always took it to the dealership to have the oil changed and other work every 3000. 2 of the last 4 oil changes cost me over $400 and $600 due to what I thought was work required to maintain the warranty, finding out later that this was false and the service people lied. In the last 4 oil changed I reported excessive oil consumption, 1 qt per 1000 miles at least. They told me this was normal and to be expected. I was 4 hours in to a 8 hour drive when the engine failed. I had checked and filled the oil before I left, in 4 hours it consumed over 3qts. It took me at least a month of dealing with the warranty company to cover as we had a lifetime powertrain warranty. They were not going to cover it due to lack of lubricant. As I told them the engine was failing before this incident. The dealer did not record my requests to find the oil consumption problem. It has now been 4 months, still making car payments and waiting for them to put a used engine in it. We were not offered a choice of whether used or rebuild. This is a known problem and have found class action suits for similar vehicles but for whatever reason earlier and later models are included, same engine and same problem as those part of the class action.
