The vehicle was repaired under the major engine failure recall. Took the dealer months to replace the engine and now they are reporting the transmission is bad too. The car had absolutely no issues pre engine failure leaving me stranded. From reading up on forums I think transmission failures are just as common as engine leaving you stranded on a busy highway.

The contact owns a 2019 Hyundai Tucson. The contact stated that while driving approximately 55 MPH, the check warning engine light started flashing and the vehicle started to lose motive power and stalled. Upon inspection, it was discovered that the engine oil level was very low. The vehicle was towed to the local dealer, but the cause of the failure was not yet determined. The contact stated that an oil consumption test was being performed by the dealer. The manufacturer was notified of the failure. The failure mileage was 38,000.

On November 8, 2023 my check engine began flashing and my car lost Speed/Full power. I knew there was a knock sensor issue because I had this replaced in May of 2023 in order to comply with extended warranty services. I immediately pulled over to see if there was an identifiable issue. I was able to make it to a local orileys and they did a diagnostic check. It gave the p1326 code which I researched and found this to be the dreaded "needs a new engine code". I wasn't able to get an appointment until November 21st with a dealership. The one in my area wasn't taking anymore due to have over 100 vehicles with the same issue. My car has been at a dealership now since my November 21 st. It's extremely difficult to get a call from these people with any information. I called Hyundai and got a case manager, but that wasn't much help either. He said the dealership was very difficult for him to get in contact with as well. After numerous attempts and no returned calls or texts, I was finally asked for my maintenance records which I sent. I have all oil change records which showed the maintenance was done and in the correct manner and time frame. On January 10th I was told that my issue was not the rod bearing issue that is covered under warranty, but instead it was a piston slap in my engine and that Hyundai had agreed to pay for half of my engine replacement. My cost would be $3,200 plus they had already charged me $250 for a battery replacement. I feel this is Hyundais way of skirting around the warranty wording. The piston slap needs to be covered under their extended warranty. This is all related to their bad engines. There was a specific campaign focused on the p1326 code. I have been without my vehicle for 3 months now and I'm still making payments on an auto loan and paying insurance on a vehicle I can't use. The service manager told me that my car was still drivable, but it's NOT SAFE His exact words. Was notprovided a rental and told it's notcovered

On [XXX], my wife and I were traveling westbound on [XXX] in the left hand lane approximately 30 miles from Lincoln, NE. I noticed blue smoke coming from my exhaust. I had to maneuver to avoid traffic in the right hand lane to exit. The engine and oil light came on about 30 yards from where we were able to stop safely. There was a large amount of oil on the ground under the vehicle. The vehicle was towed to the nearest dealership in Lincoln, NE. On [XXX], the service manager called and asked who last changed my oil. He explained that the oil plug "was left loose, upon diagnosis for the oil light being on, removing the underbody shield to drain the oil out to inspect it, the plug fell out as it was laying on the shield." Prior to the vehicle becoming disabled there was not any indication of the oil plug being lose such as oil residue on the car or leakage appearing in any driveway. The oil was last changed in early September with over 5000 miles driven. The oil change was completed by Walmart prior to the issuance of the TSB #[XXX] to replace the one time use crush type gasket and to confirm no old washer is stuck in the opening. The dealership has not submitted this for a warranty repair and claims Walmart is the responsible party. The TSB #[XXX] indicates that if engine damage occurs from not following the guidelines is subject to warranty chargeback. However, at the time of the oil change, TSB #[XXX] was not yet issued. It seems odd that there was no oil leakage or oil residue on the car prior to [XXX] that the oil plug would suddenly back out unless the oil plug/pan has some sort of defect. It may be reasonable to believe that Hyundai does not want to upload the warranty on engines that are known to have issues. We have submitted a claim to our insurance company to investigate if this was caused by hitting something on the road and have submitted a claim with Walmart.

I was just entering the expressway about 70 miles from my home, and the engine light came on in the vehicle. I could not accelerate to more than 52 mph even with the pedal to the floor. I had to drive home in the right-hand lane with my hazards on. This was the second time this happened within a month. The first time the dealer replaced the knock sensor after one week. It ran fine for 3 weeks and then the exact same thing happened in exactly the same place 70 miles from my home. My car has been in the shop for a week now, and they still don't know what the issue is, even though they are communicating with Hyundai. I see a pattern here after reading so many similar complaints from other people owning a Hyundai Tucson.

I was driving on the highway. The engine began making a ticking noise that momentarily went away and then quickly got louder. I saw white smoke out of the back, pulled over, and then saw black smoke from the front. The check engine light only momentarily came out AFTER the white smoke was visible and I was actively pulling over. I ran out of the car, and turned to look only to see a fire under the engine bay. I did not have a collision nor hit anything on the road. Engine had full synthetic oil in it, and the oil was changed less than 10,000 miles precious. (Also checked oil level/condition the week before). The car went from driving fine, to entirely engulfed in flames within 2-4 minutes. Maine state police: case# 245000657 The vehicle has not been inspected by the insurance company yet. The report will be sent to me, and it is currently available for inspection upon request. I literally could have burned alive. My family could have been trapped. I was on the highway, LUCKILY I decided to pull over when I did. If I did not, within 40 seconds I would-??ve been engulfed in flames. I have most certainly not been sleeping well in the least bit. The only warning sign happened 5-10 seconds before I was out of the vehicle.

Dear sir, my 2019 Hyundai Tucson has been in and out of Milford Hyundai five times now they say it is in oil consumption problem they say they requested a new motor. This last time my grandson was in the car we were on the highway out of nowhere the car would not go over 30 miles an hour light was flashing. I got off the highway and called AAA that was eight days ago previous to that it has been checked and towed in three times and driven in while the light was flashing And not going over 30 miles an hour I have not heard from anyone in service. They have not gotten back to me to let me know what-??s going on. Their customer service is awful. Please advise I am in my 60s they are taking advantage of my age and me being a woman who has duties and works and grandchildren and a mom I need a car.

My 2019 HyandI Tucson-??s engine light came on, so I checked my engine oil and found it to be 2 quarts low on oil, so I added the missing oil and come to find out that 2 weeks ago I had added one quart of oil. That mean in 3 weeks I added 3 quarts of motor oil. I brought the car to our HuandI dealership where we have our vehicles serviced and explained to them to check for engine oil leaks and when I came back to pick up the car, they told me there was no sign of any oil leaks. So if there are no leaks, where is all this oil going? The engine runs just fine but it-??s burning much to much oil. I mean you shouldn-??t have to put one quart of oil every week, that-??s just crazy.. I will have to bring the car back to the dealership in Centereach NY., and tell them to check again, this car is driven locally by my wife and she never drives over 55 MPH, even on the expressway. This car was never abused. I have a 2004 Chevy Venture with 195 thousand and I never put oil in it, I just have it replaced every 3 thousand miles, that-??s it, I did notice that we aren-??t the only ones that have this problem with this model car, that-??s insane. I may just have to write a letter to the CEO, if they can-??t find the problem. Sincerely, Vincent

On November 13, 2023 I was driving the vehicle and the check engine light came on and it went into "limp mode". I was well aware of what was happening because this is at least the 4th time this has occurred since owning the vehicle. It happened in Dec of 2022, Feb 2023, and again on July 6, 2023, The last time it happened the dealer had it for over a month and could not "reproduce" the problem, so I got the car back without anything really haven been done to fix it. Same as in Dec 2022 and Feb 2023. I had to fight to get the dealership to get me a "loaner" rental and had to pay for it out of my own pocket to start with. Eventually after many, many phone calls, voicemails, emails later - I did get reimbursed. But this did not happen until I email the President of Hyundai and all the executives of Hyundai. I didn't get the car back until a month later and still nothing was done. So here were are 3 months later and it's throwing the same issue/problem and I am back at square one. At this point in time, I am not interested in having it "diagnosed", all I want is for Hyundai to do a "buyback" so that I can get into a vehicle that I can trust to be reliable and not breaking down for no apparent reason every 2-3 months. This is totally ridiculous and the government needs to do more to hold Hyundai accountable for these pieces of crap cars they've put on the market. Irritated is not even the word. Will be calling the Western District Manager today as that is the last person I talked to back in August when I got it back - he said to call him directly and he would "take care of it".

Oil consumption issues. Presented at oil change with very little oil, no warning light, followed by a loss of a quart every month following. Contacted Hyundai for oil consumption test. Dealer said I would have to replace the oil pan gasket ($600)before they would start the test from Hyundai. Loss of power or engine seizing could be dangerous. I feel Hyundai shoud replace the engine and reimburse me for the oilpan gasket.

My engine has been losing oil with no leak. 1st shut down was 02sensors crank shaft, check engine light still on took it fixed it not sure how. Brought it in for upgrade in security took it out and a week later didn't start.

I do nit know what to do but I have already put 1000s in fir service rental tow I literally cannot pay 2600 to get car back to prove the problem and eat it it isn't fair well jotting is but this has got to be illegal so ehow...
