While driving on the interstate, my Tuscon started flashing a yellow check engine light and lost power. I had previously had it in to question why it would jerk when just starting. Dealer found nothing. We were able to safely get to the safely to the side of the road. It was towed to a dealership. The dealership said I was going to need a new engine. We did put in a good will warranty claim which the company is currently working on needing pictures from all parts of the engine and the dealer is working with them.. The car is a 2017 and only 107,000 miles.

Engine started to misfire on PA turnpike, causing loss of power. Engine light came on. This was on a stretch of road with downhill s-curves at night. Car has been using a quart of oil every 500 or so miles. Turbo disintegrated at 100,000 miles, this current incident happened at 120.000 miles. I believe they are related. So far, Hyundai say that there is no compression in at least one cylinder and they have to disassemble engine to determine extent of problem. Engine codes stated multiple misfires in cylinders 2 and 4.

EXCESSIVE OIL CONSUMPTION causing engine failures. Excessive engine oil consumption, will also shorten the service life of, oxygen sensors and catalytic converters, spark plugs and much more. ALL which I have had to replace since buying vehicle used in May 2021. This vehicle is not on the vehicle engine replacement recall campaign and I am not sure why. THERE IS OBVIOUSLY A MAJOR ENGINE MANUFACTURING PROBLEM. Hyundai should be responsible for manufacturing problems and they also should do what it takes to fix the problem. MY REQUEST: for Hyundai to reimburse me the money I have spent fixing, repairing and money spent on oil to operate this vehicle. AS all the information shows, this is a manufacturing issue with the engine and NO VEHICLE should consume/burn this much oil. It has been proven that EXCESSIVE OIL CONSUMPTION causes engine and parts failures. THERE are no leaks detected either by the dealership or repair shops. Frequently having an oil change doesn’t change anything. I had an oil change (yes I have all receipts of repairs) less than a month ago and I have already had to put in 2 quarts of oil.

I was driving to work after dropping my son off and I took a right turn onto a street and my car slowed down and the check engine light came on, flashing. I continued to drive to work as I was one minute away and needed to get off the street asap. (where I turned had no room for pulling over). I parked my car. I had a prenatal appointment to go to, so I started my car. No check engine light when started until I got on the on ramp to the mass pike, my car went from 50 to 35 in a matter of minutes. I went into the breakdown lane until the next exit which was only a mile or so. I pulled into a gas station and called my husband to come get me as I still had an appointment to go to. After my appointment we retuned to my car and had it towed to the dealership as it is not safe to drive while pregnant. They told me it may be an engine issue and they will try to expedite my car. What annoys me is that this happened before and they claimed it was because I was over my oil change mileage and deemed it my fault and made me pay almost 300 for them to fix it. Yet I feel as if that just bought my engine time before it actually failed. This also happened with my 2015 Sonata Sport back in like 2018/2019 before someone rear ended me and totaled me. But what is my luck that this happens with 2 of my Hyundai. It is very frustrating.

I have a Hyundai Tuscon 2017 ECO and I am experiencing the same engine symptoms as others involved in recalls. The car is only 5 years old but I have noticed that it has stuttery starts from stops and when just trying to accelerate. The engine would often jerk while driving. The vehicle is at 111,000 miles and now the engine is knocking and has very weak take off to the point it’s not drivable. This poor take off has almost caused me to get hit multiple times. There is no telling when it would happen. After the knocking started I spoke with a mechanic who said that the engines burn oil quickly which I have never been told in the past five years. If this was the cause I would expect the manufacturer to inform the owners that is an issue. No one in the past 5 years worth of oil changes (including many at the dealership) mentioned this until the engine needs replaced. I would expect a engine to last longer then 5 years and 111,000 miles before giving out.

October 7, 2022 my wife with my 7yrs old granddaughter was driving on the highway. She stayed in the middle of 3 lines. At some point the engine lost power shaking badly and quickly slowed down to 30 miles/hr in 70 miles/hr speed limit zone with semi trucks moving in quickly and honking. Thankfully she managed to stop safety on the side of the highway. Later diagnostic showed multiple misfire on all cylinders and opening the engine showed cracked cylinder. I, backed by 2 independent mechanics opinion, think the crack existed long time before the incident. I reported to the car dealer service excessive oil consumption (1qt every 600 miles) only to be told it’s normal. Then the Hyundai Corporation denied 100 k warranty repair blaming without any proof, poor maintenance

My car Was taken care of always getting oil changes whatever it needed done.. one day my car started making a rattling noise. it turned out it was my engine. I do see a ton of my model car 2017 Hyundai Tuscon been having same problems on recall I believe mine is under that category but saying its not. Im literally having the same exact problem as these people that have the recall for their cars. I was literally on the highway and thought I was going to die because my engine was making so much noise and this came out of nowhere the car is in good condition and less than 100,00 miles on it it shouldn't have a engine fail.

The dual clutch intermittently shakes and hesitates while accelerating from a stop. Also, sometimes it's sluggish while driving and feels like it might stall. This is dangerous because if I needed to speed up to avoid a crash, I'm afraid the car may hesitate and be involved in an accident. There are recalls for other Hyundais with the dual clutch transmission for this same problem. Available for inspection upon request. Didn't show this to my dealer. No warning lamps. The engine has always intermittently shook and hesitated when accelerating from a stop. The feeling that the vehicle is sluggish and that it may stall AFTER accelerating while stepping on the gas pedal started recently around 19,300 miles on the odometer. I also reported this issue to Hyundai.

My daughter was driving on expressway the vehicle suddenly lost power. Vehicle began to shudder and became difficult to steer and control. On board diagnostic codes P0300 & P0301. Towed vehicle to my independent mechanic. His diagnosis was mis-fire in cylinder 3 and total compression loss in cylinder three. Major engine failure. Vehicle has 1.6l Gamma GDI engine. Vehicle was then towed to Hyundai dealer. Awaiting diagnostic from dealer ( four week backlog), but there where 85 failed engines ahead of me. Called three other dealers, all had diagnostic waits for engine failures exceeding 5 weeks. If failure is even covered the wait for replacement engines is stated as one year. Sudden loss of power impacted safety controlling the vehicle. I think the issues with this engine class will be well known to NHSTA and report so the size & impact of the issues is best understood at NHSTA.

There are two problems with the car. The first is excessive engine knocking. I brought it into Island Hyundai on Staten Island. They originally denied there was an issue with some of the cars. They said for a $169 they would do a diagnostic test. They serviced the car and said it was fixed after initially denying there was a problem. The car seemed ok but over time the knocking returned. I return the had to do major engine work ie: cam shaft. Timing chain… On the second visit I complained of excessive oil loss. They checked and said it was a leaking valve cover gasket. They replaced the gasket. I took the car back and drove it. There is still excessive oil loss and still minor knocking occasionally when the car starts to move in first gear. I brought the car back in to the dealer, they claimed there was no knocking but that is what they said after the first time I brought in the car for service. They did not state that in writing on my invoice. They told me they sealed the oil access points and I should not check the oil. They did an oil consumption test. They told me to drive it and return in one thousand miles. I am returning tomorrow, Monday October 2nd to the Island Hyundai service department to have the oil levels checked. I asked if they will replace the engine if the engine fails during the consumption test. I only received a verbal yes from the service department manager at Island Hyundai. I contacted hyundai corporate to complain and have them assist me. I requested written confirmation of the engine replacement if it failed during the consumption test, They have done virtually nothing. I asked them to confirm in writing if my engine would be replaced if it failed during the consumption test. I was told they are not responsible and would have the service manager contact me. To date no one has contacted me. I have checked and I do not see any recalls for my car regarding these issues. I do however see other cars being recalled for the same issues.

My vehicle has a high oil consumption problem. The problem was bad enough that it separated my catalytic converter. I had to pay 20% of the cost to fix. My share was over $500. It was said that this was caused by the high oil consumption issue. So the next step was started. I had an oil change with the intent that I would bring it in at 1000 miles to have the oil level checked. At the time of the oil check, I had driven 992 miles, the oil was checked and I was down almost two quarts. It does not leak oil on the ground when parked. The dealership contacted the manufacturer and they stated that was not an issue. The issue is a thrown rod, blown engine-from high oil consumption. I contacted the manufacturer. They sounded very sympathetic. However, they decided there was nothing they could do. Gave me $200 for my inconvenience and sent me on my way. My concern is what if I am on the highway going 70mph and my engine blows. What if I am in the left hand lane. What if my grand children are in the car with me. What if I can't get to work because something happens. I feel like I am driving a time bomb. I don't feel safe driving it any distance. Part of their not doing anything for me was because I didn't do anything before 60,000 miles. Well, I am the second owner. and I bought it at 61,000 miles. I am putting in two quarts of oil every ten to fourteen days. I am hoping you can help me get my vehicle fixed. Thank you for your time.
