general problems of the 2019 Hyundai Tucson - part 2

I have had to replace the exhaust manifold and catalytic converter twice since owning my car. I have owned my car since 2020 and bought it at 23,000 miles. The car now has 100,000 miles - all highway. The code p0240 has displayed again and the dealership said I need to replace the catalytic converter and manifold for a third time. The car burns synthetic oil very quickly as well. Dealership has found no leaks of oil. I have to change oil every month because of how quickly the oil burns. I have conducted my own research and have found several other owners of 2019 Hyundai Tucson are having similar issues. I encourage Hyundai and its partners to initiate an investigation. This could cause detrimental damage to the engine. Something is wrong!.

The contact owns a 2019 Hyundai Tucson. The contact stated while driving at an undisclosed speed, the check engine warning light illuminated, and the vehicle lost motive power. The vehicle was towed to the dealer where the vehicle was diagnosed with catalytic converter failure and sludge in the engine oil. The contact was informed that the engine needed to be replaced. The catalytic converter was replaced. The vehicle was not repaired. The vehicle was towed to the residence. The contact stated that the vehicle was at the dealer for 55 days. The manufacturer was made aware of the failure and a case was filed. The contact was informed that the engine was not covered under warranty. The contact was informed that because the history of the oil changes was consistent with Hyundai, the engine was not covered under warranty. The failure mileage was approximately 70,000.

My car lost power and was shaking while driving, the dealership service department told me that that my car was producing a code for a misfire in my exhaust valve chamber #3 and I could replace this for $4400 but in a few months I would need a new engine so they recommended I replace the engine for $8000. I am 1000 miles over my warranty so Hyundai is refusing to pay for this. I currently finance my car and owe $22000 on it still and can not afford to fix my car out of pocket. My car has been at the service department since 9/6/2024, I’ve researched this problem with this make and model and thousands of Hyundai owners are being denied for new engines because the engine failure was not caused by the rod bearings, ultimately both of these concerns and problems are cause from oil consumption and these vehicles burning oil. After multiple exhausting attempts to clear this up with Hyundai USA corporate and my local dealership. I’m am now working on other options. Driving down a 70mph highway losing acceleration is dangerously unacceptable.

The check engine light came on and then started flashing. It was 3 quarts low on oil and there were still 1,000 miles left before the next oil change. The oil has been changed regularly since we purchased the Tucson in December 2023. A mechanic looked at the vehicle today and said metal shavings were in the oil and the engine needed replacing. The 2019 Hyundai Tucson got good reviews and was considered a safe vehicle for teen drivers, but now I'm wishing we purchased something else for our kids to drive.

The drain plug was loose, even thought the mechanics ensured it was tightened. This is another case out of many of 2019 Hyundai Tucson owners who have found the drain plug to be faulty causing loosening and then falling out causing all oil to drain quickly and without warning. My engine unfortunately died mid drive while at the base of a large bridge, causing safety risks to myself and my passenger, as well as other drivers on the road. The engine lost so much oil at once giving no chance to even be warned about malfunction, as we were driving and it just fell out. My engine seized completely. This is not the first time Hyundai parts have done this, according to other owners, mechanics and other forums. Hyundai still has no recall for this faulty parts and offers no assistance to remedy a potentially life threatening situation.

The contact owns a 2019 Hyundai Tucson. The contact stated while driving 50 mph, the vehicle lost motive power. The check engine warning light was illuminated. The contact was able to pull to the side of the road. The contact stated that upon turning off and restarting the vehicle, the check engine warning light remained illuminated. The contact activated the hazard lights and drove to the residence. The vehicle was taken to the dealer, where it was diagnosed with a possible knock sensor failure. The vehicle was not repaired. The manufacturer was notified of the failure and a case was opened. The manufacturer later informed the contact that the VIN was not covered under an unknown recall. The failure mileage was approximately 76,000.

The car barely has 50,000 miles on it and I had to replace all the tires rotors and brakes. Then a week later we were driving and it started making a funny noise and it would not drive more then 30 mph. I am going to have it towed to the dealership and see what the problem is. I have been reading about a lot of people with this same problem for faulty engine. I will sue them if this is the case this happened another time to me and I sued them under the lemon law.

My car is burning oil like crazy, having to top off engine with 1. 5 quarts between 5,000 mile oil change with synthetic oil. Took to Hyundai for oil consumption test. Let them know I'm having issues with burning oil, and my check engine light comes on often. They looked at my car saw enough of a problem according to advisor to skip first step of oil consumption test and jump straight to step 2 an engine combustion cleaning, which cause multiple more codes to come on. Drove the 1,000 mile 1378 to be exact because I explained to them that I couldn't bring back at exact mileage and was told that was fine. I was toldy car was only a quart low and that that meant everything was fine and that they would now honor the warranty. I am using in ungodly amount of gas and my engine oil smells like straight gasoline. I explained this to the manager and he said he resubmitted to try to retest again and was denied. I do not know what to do at this point. The advisor even said he didn't agree with their decision but it was up to them. His hands were tied. I am a single mother still paying on the car and only bought new because of the warranty. I provided immaculate proof of oil changes and maintenance. Please help ??.

The engine start having a knocking sound, it got worse until stop, it burned the oil faster.

I was driving approx 55mph on highway 74 in my 2019 Hyundai Tucson when the check engine light came on and the engine started to stall. I felt the acceleration dying down in the middle of busy highway traffic. Gray smoke started coming from the hood cracks. I luckily was in the right lane already, so when I could I veared off to the shoulder and the car quit. The smoke was increasing badly. Ppl from the highway were yelling its going to blow up get away from it! I was so scared. I grabbed my phone and keys and ran as far as I could while dialing 911. Within a couple minutes flames were swallowing the entire engine and front of the car. I am furious. I researched online and Hyundai has had many similar incidents with this car and other with this engine ! these need to be banned and taken off the road before they kill anyone else. Ppl have been injured and killed from similar situations just like mine. I thank god I made it out of this horrific situation alive. But now I have no car and am at risk of losing my job and then housing . I thought I would have this car for years. Now I'm traumatized and without transportation.

- replaced catalytic convertor twice - check engine light on , needs another catalytic convertor - exhaust fumes are coming back into my car through the ac vents , I’ve had to pull over due to being nauseas and extremely dizzy. - the dealership will not answer my phone calls , but will answer another phone because I have called from another phone and they picked up immediately - was told from a service advisor that they would not help me “ unless the car blew up “ - my car did recently ,8/8/24, shake aggressively, the check engine light flicked rapidly and a strong puff of fumes came through my car - they will not help me because they stated that my rod bearings are not rotted therefore I do not qualify for assistance and everything would come out of pocket , the engine replacement , the catalytic convertor due to me being a few thousand miles outside of my 100,000 warranty. - I have the invoice stating oil is leaking profusely out of my engine - I was told within the last 2 weeks that if my car was to actually seize , Hyundai is not responsible bc when they kept telling me to bring my car in , they kept diagnosing it so they quoted me at about $5k to fix everything.

’ve replaced the catalytic converter two times , the check engine light is on so it says I need another catalytic converter, that was in June 2024. The car was at the shop yesterday, needs catalytic converter and oil is pooling all throughout the car , fumes from the exhaust are coming back into the car which makes me physically ill. The engine revs and slows down by itself, it goes through oil on such a regular basis that I have to carry a full size jug of oil with me at all times because I need to put it in before I leave work and when I am on my way back home , the dipstick will be dry.

Engine failure. Car suddenly stop and engine light lit on.

The contact owns a 2019 Hyundai Tucson. The contact stated while driving approximately 40–45 mph, the vehicle failed to accelerate as needed. The vehicle failed to accelerate about 35 mph. The vehicle went into limp/safe mode. The check engine warning light was blinking. The vehicle was towed to an independent mechanic and the contact was informed that the failure was due to metal shavings being in the oil. The contact called the local dealer and was informed that there was no recall coverage on the vehicle. The dealer informed the contact about diagnostic testing the vehicle. The vehicle was not diagnosed or repaired. The manufacturer was contacted and opened a case. The contact was informed that the vehicle was not covered under recall. The contact related the failure to NHTSA campaign number: 20v543000 (service brakes, hydraulic). The failure mileage was approximately 92,000.

On 05/11/2024, I accelerated onto the freeway at which point my vehicle would no longer go past 50 mph with the pedal to the floor. I had my two small children in the car at the time. It was dangerous as cars around us were going 65+ mph. The check engine light started blinking when this was occurring. Prior to that the check engine light had been on because the dealership claimed they didn’t know why it was triggering and that they have to take my engine out and replace it just to explore the issue. I don’t have the money for that. It has a knocking sound, a pungent fuel smell and it still won’t accelerate. I only have 85k miles on the car.

I have to add oil to my every 2 days. . There is no leaks and I get frequent oil changes. Also acceleration to meet state limits my rpm go super high not wanting to shift. Again no leaks and have checked so there is good transmission fluid in it.

I was driving on the highway when my vehicle started decelerating and shutting down completely. I ended up safely pulling over because it could’ve been a serious accident and called fhp they tested my car code p1326 came up I had it towed to the dealership where they assured me I had the extended warranty and that the car should be covered and I don’t have to pay out of pocket. What the dealership told me would take 2 days has now been almost a month and still counting. I’ve had 3 denials for engine replacement due to being outside of warranty with Hyundai even though I have the extended warranty. The dealership has sent pictures and spoke with my case manager at Hyundai to confirm that the engine failure was due to the bent connecting rod bearing that is again covered under warranty. They came back and said other codes populated showing the cause was not the rod bearing but that has to be false. One of the other codes was regarding coolant and I’ve never had any issues with my car overheating or anything prior to my engine shutting down on the highway. I never had any flashing lights or warning signals on my dashboard. This was very unexpected and I refuse to pay for a repair that I didn’t cause especially when this is consistent with Hyundai and their engines. This is a 2019 I should not have any issues. I need a solution quick.

I was having oil consumptions issues which meant I had to put a quart of oil in my car every 500 miles I drove. Then I was driving when my check engine light started flashing and now my car can't drive without shaking a lot. I can't drive it anymore.

Check engine light comes on it has come more then 5 times. I take it to the dealership. They tell me they are doing an oil consumption test this makes the 5th one. Lane assist when trying to move away from a vehicle it pulls back almost getting you into an accident.

See attached document for complaint.

Engine stalled while on the road with no warning lights. Seized and doesn’t start. Hyundai said that that it was engine neglect because of sludge yet we consistently got the oil change.

On March 13, 2023 while I was driving at about 70 mph on PA route 66, the engine suddenly stalled and fortunately, I was able to move to the emergence lane. I turned off the power and restarted the engine, and it worked. This is the third time that I have experienced the same issue, with other two on I-376. I also couldn't start the engine after refilling gas, so I had to wait for about 15 minutes. I took the car to a dealership but the diagnosis did not show any problem. There was not error code at all. On the internet, several possibilities were mentioned, but I do not have any idea about the root cause.

Was driving home from shopping on highway- lights flashed on dash and check engine light came on. Driving on highway and car goes into “limp mode” and will not go over 30 mph. Almost got rear ended by car coming up from behind traveling at normal highway speed. Dangerous!!! this is 5th time this has happened! the manufacturer needs to address these issues. Its happening to way too many people! [xxx] theres a facebook group too but I can’t seem to get the url. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I have a Hyundai tuscon 2019, which was pre-certified by Hyundai. This particular car was part of a lawsuit because of a knock sensor issue. The lawsuit information is here: https://hma-e2. Autosolutionteam. Com/production/hyundai_e2_portal. Nsf/home. Xsp the knock sensor failing is not really what causes the safety issue. The engine symptoms when the sensor fails is the issue. The engine goes into "safety mode" which limits the car to a significant slower speed. The problem is that Hyundai has now tried to fix this issue twice on my vehicle, and the knock sensor continues to fail. To be clear, they've replaced the sensor twice. Based on the lawsuit, the court mandated them to fix the knock sensor. They have done that free of charge, but the sensor continues to fail. To me this sounds like a manufacture issue. It is incredibly dangerous when you're on a highway and the sensor fails. It happened to me, and it was almost catastrophic. The car slowed down and there is nothing you can do about it. I noticed there was something wrong very quickly and put my hazards on. If I didn't, I may not be writing you here. You could easily get into a significant accident, and from that could lead to injury or loss of life. I am asking for a review of this. I have my service records as well as recorded conversations with Hyundai corporate regarding this issue. Service records are attached. I live very close to NHTSA hq and willing to come in if necessary. To me, this is concerning enough for that. .

Bought the car in August with 82000 miles and within 2 weeks engine light came on and has had a knocking issue, carmax could not get me in for 4 weeks from the date I called for a "diagnostic testing". After replacing knock sensor -- engine stopped on 3/3/24 and now needs to be fully replaced.

Engine failure needed to be replaced just over 52,000 miles.

The 2019 Hyundai Tucson was being driven home when all of a sudden acceleration was reduced to 25-30 mph. The engine light went on while this happened. Got the car home, thankfully was off the highway and had it towed to the dealership. Dealership informed me that it was an engine problem- a cylinder was blown and new engine would be needed on a car that had just reached the 40,000 mile mark. 40 other cars were brought into the dealership the same week and all needed new engines. If this car stopped working on the highway the consequences would have been dire! it is almost 2 weeks without a car- dealership had no loaners left and we still don't have an answer from Hyundai if they plan to cover the engine still under warranty. We were told Hyundai had been denying allot of engines under warranty. And we were told it takes a long time to get an engine even if approved by Hyundai. If I must rent a car for a month or more, it will be very expensive. If 40 owners showed up at the same dealership in one community in the same week what is happening nationally and why hasn't Hyundai issued a recall? do we have to wait until people's cars stop operating at full speed on a busy highway causing multi care pile ups before Hyundai speeds up response to repair but more importantly notifies owners of their vehicles this is a problem- a big problem!.

Engine failure I was driving down 422 east to king of prussia. My car jumped then began creating a sharp chirping sound from under the dash. I was in the middle of traffic. My safety was put at risk as there was no warning. I was able to get off the exit but immediately after, the cars engine light began to flash, oil censor, and I turned my car off. I was stranded on the 422 overpass with cars zooming past me. I created a danger to myself and others as it was difficult to see around me coming off the exit. The vehicle is currently at faulkner Hyundai awaiting a submission to the warranty company with me on my hands and knees praying to god it gets approved.

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.

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.

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.

On 12/17/23, my wife and I were traveling westbound on i80 in the left hand lane approximately 30 miles from Lincoln, ne. I noticed blue smoke coming from my exaust. I had to manuever 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 12/18/23, 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 #10247189 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 #10247189 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 #10247189 was not yet issued. It seems odd that there was no oil leakage or oil residue on the car prior to 12/17/2023 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.

The components that failed are the engine and transmission and parts associated with the functionality of these parts. It is currently in the shop but will be available for inspection upon request once repairs are complete. My safety and others were put at risk when these malfunctions occurred (driving incredibly slow on the highway could cause an accident, accelerator malfunctioning that might break, broken down late at night hours from home, parts catching fire from leaking oil, etc. ). The problems have been acknowledged by my warranty company and the two repair shops that have serviced it. My car was inspected by geico insurance company after I got rear-ended and needed to file a claim, however, the inspection was not specifically on my engine/transmission. The warning dash lights didn’t seem to come on until it was too late, especially during the transmission issue. I was driving around for days leading up to this issue thinking it was acting weird because it was due for an oil change but when I got one and nothing improved, I knew something was wrong. The check engine light did not come on until the car started to actively shut down and not move when I pressed the gas. The full detailed complaint is attached and receipts for repairs are available upon request. Attached is an overview of parts and pricing from the warranty company for the two claims.

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.
