2019 Hyundai Tucson engine complaints
Page 4 of 8: complaints 71 to 100 of 204, newest first, as owners wrote them.
While driving, my vehicle stopped moving forward and the engine light came on. I pulled over and called for a tow. The service department at the dealership the vehicle was towed to said that the vehicle had less than a quart of oil in it. I just had the vehicle serviced 2 months prior. The service department changed the oil, oil filter and air filter. They drove the car and heard knocking. They found the rod bearing to be bad. They said it needed a new engine. The vehicle has approximately 51,000 miles. I never had any issues prior to that day. The car manufacture is refusing to replace the engine because I am not the original owner, not because the engine isn't defective. This is a 2019 Hyundai Tuscon with engine 2.0L L4 DOHC 16V. I believe there is a known problem with this engine, but the manufacturer doesn't want to admit to anything, nor do they want to resolve the issue. My vehicle could have caught fire. I could have been in an accident. I just want the car company to replace the engine without any cost to me. I would even pay for the labor, but they need to pay for the engine and any parts or tests that come with replacing an engine.
My catalytic converter failed at roughly 70k miles (confirmed by mechanic and replaced). I have now been having transmission issues ever since, starting with the rpms jumping up on their own when trying to downshift (reproduced by mechanic) and ending with the car fully going into limp mode while in the middle of driving on the highway at speed. The former never triggered a light or produced codes, and with the latter the CEL flashed three times at the very start of the breakdown, and then went off and never came back on, despite the obvious problems the car was having.
The contact owns a 2019 Hyundai Tucson. The contact stated while driving 45 MPH, the accelerator pedal was depressed; however, the vehicle failed to respond. The check engine light warning illuminated, and another unknown warning light flashed. The contact was approaching a traffic light and then while attempting to accelerate, the vehicle failed to respond. The contact pulled over to the side of the road, parked the vehicle, and turned off the vehicle however, the vehicle failed to restart. Several independent mechanics were contacted, and the contact was made aware of a possible recall related to the failure. The contact called the manufacturer and was referred to the dealer for assistance. The vehicle was towed to the dealer to be diagnosed, and the contact was informed that the engine was knocking. The vehicle was not repaired because the manufacturer was waiting on the maintenance records for the vehicle. The manufacturer was made aware of the failure. The failure mileage was approximately 92,000.
The engine sensor knock sensor went out on me on I-95. I called the dealer who sold me the car no action as of yet. Took it to a dealership service and had them diagnose it and they confirmed it. They informed me of a recall for Hyundai that year (2019) but not this model. They were baffled why this model was not recalled when they have several models with engine issues. They informed me they were not going to fix it because it will not work but I could risk it somewhere else. I took it to Precision Auto Tune and the dealership was correct. It only work for 48 hours if that. Confirm by more mechanics and the engine is no good

Unknown
While driving the car felt like it was going to shutoff multiple times. It had been experiencing an unusually high consumption of oil since it's last oil change. It would also tend to surge and excelarate unexpectedly while driving. The check engine light came on only once and then shut off. The car is currently at the Hyundai dealer. The service person says we need a new engine. These incidents happend while I and my wife were driving in separate incidents at different days and times. I was with my family and had to apply the brakes lest we run into cars in front of me when it surged unexpectedly.
Engine failure will be caused by shrapnel in the engine (Dealer told me Hyundai is aware it was not vacuumed out properly in this particular batch of engines) leading to ruts being warn in the cylinder causing oil to leak past piston rings. Loses so much oil quickly. Extended warranty may deny due to 3 missed air filter changes
I took my vehicle to my mechanic for inspection check up. My mechanic told me and supplied paperwork from their scans that the P0420 sensor in the cat converter was shot again (3x in 5 years) and needed to be replaced. The engine light had come on 3 weeks beforehand and I had it read and knew what it was. They sent me to Hyundai dealer as it was under warranty with documentation. I get to Hyundai dealer tell them it needs the sensor for inspection and an investigation for oil leaking from back of the engine. I also told them I was adding 2-3 quarts of oil between oil changes. They told me my mechanic over filled oil by .5 quarts and that's why the engine leaked. They investigated after I disputed by saying an oil change had been performed the day I brought it to them and found a bad head gasket, fuel pump seal, and oil pan seal. They charged my extended warranty for those repairs, shut off engine light for cat converter sensor without replacing it, and made me do an oil consumption test of 1000 miles. Car was still not inspected at this point. After 35 miles check engine light comes back on. Cat converter sensor P0420. I take it back in. They tell me they won't replace it until the oil consumption test is done because they need to know if oil is coming through the exhaust pipes (it was). I complete the test and go in. They tell me engine is burning .5 quarts of oil/1000 miles which is acceptable and as long as I complete oil changes every 5000 miles I will be fine. They then tell me if I want sensor replaced I'm 800 miles over warranty so I have to pay $2400 to replace. Called corporate they're only willing to cover half the repair as "good will" for the cat converter and was quoted $1300 by the dealer in question. Almost a month and still not fixed and still can't get car inspected because the check engine light is tripped by the P0420 sensor in the cat converter. It's the only vehicle my family has. I'm forced to pay to have transportation.
The contact owns a 2019 Hyundai Tucson. The contact stated that while driving on the highway at 70 MPH when the vehicle acceleration speed was reduced to 40 MPH independently. The check engine warning light had illuminated. The vehicle was taken to a local dealer where it was diagnosed that the gasket fuel pump, camshaft, timing chain, timing chain sensor, and intake cam were faulty and would need to be replaced. The vehicle was repaired, however, the failure persisted. The manufacturer was not notified of the failure. The approximate failure mileage was 105,000
While driving on the highway, the check engine line came on and my Tucson started loosing power. I quickly moved into the right lane and was able to exit the highway and pulled over. I had previous issues with the vehicle and was told it was the 1 & 2 ignition coils that were replaced. I assumed it was the same issue for the 3 & 4 ignition coils. They were also replaced but the issue was not resolved and the vehicle was towed to a mechanic shop who stated there was a piece missing off one of the pistons and he couldn't determine how that could have occurred. At this point, he said my engine would need to be replaced and apparently they are back-ordered for 6 months. My daughters vehicle - 2019 Kona, was purchased at the same time and she also lost power in her engine while driving on the freeway. Fortunately she pulled off onto the should in a very dangerous situation. Her engine had a hole and later found out the 2019 Kona had an engine recall. I have heard there are issues with the 2019 Tucson, but no recall has been issued.
2019 Tuscon with 70k miles.Engine failure, had to have vehicle towed to dealership. I have been without a vehicle for over a month and other than the dealership leaving me a message saying that my engine is seized, I have been completely ignored.
Knock sensor keeps throwing codes, the car will not accelerate over 20mph and under 2000 rpms
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
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.
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!
- 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.

formance exhaust. I bought catalytic conVerter that they told me to buy for 600+ dollars and took it to child's shop they told me that the catalytic converter isnt clogged nor is it affecting my car and provided me with these codes about the camshaft and crankshaft (P0017,P000B, P000A) which they stated hyundai should have fixed under the engine warranty because it was a recall on these engines on this year car. They stated that even if fixed the converter my car would still perform the same and 3 other mechanics have said the same and stated hyundai would have to fix it. After oil changes the oil consumption in my car is constantly getting oil before its even due for another oil change. I have already paid so much just by having people look at it, buying oil, parts, and etc. i am furious to know that i was sold a car that was recalled with engine problems and been having problems since i got it. I have 2 kids i have to get to and from school and this my only transportation. My car has been misfiring and not going over 40 miles. This is my only vehicle and hyundai has put me in a messed up situation. The recalled was may 2022 and hyundai sold me this car june 9 2022. I contacted the june 15, 2022 about the engine light they kept turning off. Car is stalling, making noise, not holding oil. Have to top oil weeks after getting oil changed
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.

’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.

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 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.
