general problems of the 2019 Hyundai Tucson - part 1

Oil consumption.

My engine has an oil consumption problem that I've been dealing with Hyundai on. The vehicle is a 2019 Hyundai Tucson. Last Friday [xxx] my car lost power on the freeway on a bridge and I began to slow down and couldn't pull over due to no shoulder. I had myself and my family in the car with me, (wife, [xxx] , [xxx] ) my car has failed two oil consumption tests and had a combustion chamber cleaning to try to resolve this issue. Now after losing power, the dealer has gone back on their word of engine replacement because Hyundai denied the claim. They are telling me the oil consumption lead to the catalytic converter getting plugged and losing power. The engine light for that has been on throughout all of the oil consumption testing (months) information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

My car has had an oil consumption problem for over a year that Hyundai refuses to acknowledge. I passed the oil consumption test because the oil burns rapidly when I have about 1,000 miles left before my next oil change. They have replaced my exhaust, catalytic converter, spark plugs, and oil release valve over the course of many visits. Every time I have the oil problem, they find something different to “fix” and I have to pay out of pocket. None of these have fixed the actual problem. The Hyundai representative I have been in contact with (after they reassigned my case to someone 3 different times - so it’s never the same person that is familiar with my case), told me there is nothing they can do to help me because the dealerships are independently owned. I am now out of warranty, although I originally brought my car there while it was still covered under warranty.

Car has had shaking during acceleration and a noise (rattle/knock/tapping) from the engine for last 18 months. Dealer “could not find any issues” until July 31st 2025 when the engine broke down with a p1326 code (connecting rod bearing failure) and the engine seized. Vehicle is under class action class with extended 150k 15 year warranty on engine for this concern. Had recall performed for the knock sensor detection system as required by class action. Dealership first asked for most recent oil change record (provided) and than informed that Hyundai declined repairs due to full maintenance records not being submitted. Have now submitted full maintenance records to dealer and Hyundai directly since I purchased in 2023 as certified pre owned. All maintenance performed as per factory recommendations in manual. Hyundai still declining repairs without any explanation.

The contact owns a 2019 Hyundai Tucson. The contact stated that while at a red light, the missing key warning light illuminated. The check engine warning light illuminated. The hazard lights were independently deactivated. The contact became aware of an abnormal odor and smoke on the interior of the vehicle and the exterior of the vehicle. The contact stated that all the door latches were independently locked, and the engine seized. The contact stated that her minor child was also an occupant of the vehicle at the time of the failure. The contact stated that a nearby police officer and other bystanders assisted with removing the contact and the minor child from the vehicle. The contact stated that it was a very traumatic experience, and the contact was very fearful for the lives of her minor child and herself. The contact had a doctor's appointment scheduled; however, because of the failure, the appointment had to be rescheduled. The vehicle was towed to the dealer; however, the vehicle was not diagnosed. The contact was offered a trade-in option. The contact declined the trade-in option. The manufacturer was not made aware of the failure. The failure mileage was approximately 52,000.

The contact stated that while driving on a main road at 20 mph the vehicle experienced a reduction in automotive power until the vehicle came to a complete stop, the contact was able to pull over onto the side of the road, and the check engine light would illuminate intermittently. The vehicle was towed to a local dealer where the vehicle was not diagnosed as the contact was advised that their VIN was not included in any open recalls. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 132,000.

Engine has been burning through oil. Started the engine oil consumption test at one dealership. That dealership has now closed leaving me to go to another dealership. They want me to start the process over again. I have had two oil changes, failed the second test and was scheduled to bring my car back for the next step in the diagnostic process. Not only do they want me to pay out of pocket again for an oil change but my car is driving worse. It didn't start the other day and it drives horribly. The safety concern I have is that the engine will seize while driving, causing an accident.

On a busy highway, my car broke down. It was due to the rod bearings, specifically, the Hyundai theta "extended warranty"/recall issue, or "recall" issue. There is currently a class action lawsuit against Hyundai. I had the car towed to hallmark Hyundai in nashville, TN. I, however, live in louisville, ky and I was making a road trip to nashville, TN. I was told by the service rep in nashville that they couldn't provide me with a loaner vehicle because I would be driving it, back home, out of state to louisville, ky. I paid for a rental car out-of-pocket. Hyundai corporate told me it would take 60 days to get reimbursed. I picked up the car at the beginning of July, 2025, after the engine was replaced by hallmark Hyundai. I was told by hallmark Hyundai that a service employee performed a test drive but it was immediately noticeable to me that there were still issues. I noticed the gears shifting abnormally and problems with acceleration once I first started driving it, post repairs, but assumed I would be told to give it time. Today, [xxx], the car began to have difficulty accelerating once again, and the engine light illuminated. I couldn't accelerate beyond 45 mph. I phoned Hyundai corporate customer care, relayed the issues, and said I needed a rental car the following morning for a job pre-hire meeting and couldn't pay for one since my credit card was already maxed out due to the first out-of-pocket rental. They refused. They told me to work it out with my local Hyundai dealership. The problem with all of this is that the consumer still incurs many hardships even though the car manufacturer is at fault and the dealerships don't always follow the settlement requirements of providing alternate transportation, a loaner or rental. The manufacturer and dealers are not held accountable and settlements that purport consumer recourse are more geared towards the manufacturer staying in business than the consumer being compensated fairly.

This vehicle was purchased by me in November of 2024. It was a one owner used car. At the time of purchase, the vehicle was inspected by the dealer and the oil was changed. It had only been driven 3000 miles when the check engine light began flashing. I took it in to a dealership and learned that it was burning oil at an excessive rate causing engine wear and damage. I have since learned that the engine will need to be replaced. I also learned that this is a very common and known problem with Hyundai engines.

The engine seized will on the highway unexpectedly. While driving on the highway the car suddenly started to slow down and would not pick up speed. I was able to get off on the first exit and make it a close to the right hand land as possible before the car stalled. I was stuck on the feeder road and at risk of being hit from behind. I cranked the car and was unable to move. While calling a tow truck and waiting for it to arrive later I tried to crank the car again and was able to drive it to the nearest safe place.

The contact owns a 2019 Hyundai Tucson. The contact stated while driving the vehicle failed to exceed 25 mph and stalled several times. The contact was able to pull over to the side of the road. The contact turned off and restarted the vehicle several times; however, the failure persisted. The check engine warning light was illuminated. The vehicle was taken to an independent mechanic, where it was diagnosed with exhaust system failure. The vehicle was then taken to the dealer, where it was diagnosed and a dtc for engine failure was retrieved due to the exhaust system failure. The dealer forwarded diagnostic test report to the manufacturer; however, the manufacturer declined to cover the repair under an unknown customer satisfaction program because the oil change records were not available. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 69,000.

My vehicle isn’t in the oil consumption recall yet it uses oil very fast then the warning light doesn’t come on till oil is almost all gone ! I’m having to add oil every month ! how can I get this paid for for free by Hyundai ?.

Back in 2024 brought car in for recall but Hyundai only scanned the vehicle and gave estimate for work done without further explanation. Left the car idle and only start it once in a while. Now when opening oil cap there’s some smoke coming out of it and a rattling sound.

The contact owns a 2019 Hyundai Tucson. The contact stated that while driving at 30-35 mph on the expressway, the engine light illuminated, and the vehicle lost motive power. The driver was able to pull over safely. The vehicle was towed to the local dealer where it was diagnosed and determined that the engine needed to be replaced or rebuilt. The vehicle was repaired. While leaving the dealer, there was an abnormal clicking sound coming from the vehicle. The mechanic determined that there was a zip tie making the sound, but the failure recurred. The vehicle was towed to another local dealer, Hyundai of louisville service department (6633 dixie hwy, louisville, ky 40258); where it was diagnosed. The clamps were not installed properly, which caused the issue. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 141,236.

The contact owns a 2019 Hyundai Tucson. The contact stated that the vehicle had been experiencing excessive oil consumption, and the check engine warning light was intermittently illuminated. The contact stated that while driving 25-30 mph, the vehicle was shuddering. The contact continued driving uphill, and the vehicle experienced reduced power and was driving sluggishly. The contact stated that after coming to a complete stop at the traffic light, the contact depressed the brake pedal firmly out of fear that the vehicle would roll backwards. The vehicle was taken to valvoline, where oil was added to the vehicle. The vehicle was then taken to firestone, where diagnostic trouble codes p0420, p000a, and p050a were retrieved. The contact was referred to the dealer for assistance. The vehicle was taken to the dealer, where the same diagnostic trouble codes were retrieved. The dealer recommended an intake manifold replacement; however, the dealer informed the contact that there was no guarantee that the repair would correct the failure. The vehicle was not repaired. The manufacturer was notified of the failure and offered the cover fifty percent of the repair cost. A case was filed. The failure mileage was approximately 103,000.

There is a significant issue for engine oil consumption that may cause the engines to seize up and require repairs and or replacement. To that end the vehicle purchased has a 15 year 150,000 mile extended warranty included. The vehicle is now in for additional repairs related to the same issues and verification if a new engine will be required.

Due to known oil consumption my car stalled due to no oil left in the engine even though there were 2,000 miles left until my oil change. I have since started to go to my local Hyundai dealership to test for oil consumption and have been tested 3 times and Hyundai is saying that there is oil consumption but it is under the threshold they consider actionable. This is very problematic and can cause many issues for myself and others.

Car uses quart 1/2 for 300miles gives no warning of lo oil level . This will lead to engine failure while driving. Dealer acknowledges consumption issues offers combustion maintenance at customer expense but service technician says save money as service doesn’t work.

The vehicle was brought in just after a month of owning it due to it was accelerating slow and driving bad salesmans sent it to Hyundai dealership for diagnosis and it came back that the motor needed to be replaced due to recall vehicle was in repair shop for over 3 months to get a new motor once returned the very next day the check engine light came back on so I brung it back to the Hyundai dealership per hub city's salesmans instruction to have vehicle diagnosis again. Hyundai advised that the vehicle needed a catalyst converter among other codes detected on vehicle.

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.

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.

Substantial oil consumption. Refilling oil once a month. Is not covered yet under engine recall. Dealership purchased from in virginia beach will not cover repairs.

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.

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.

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.

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.

Unknown.

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 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.

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.

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.

Vehicle is consuming oil at a rate of 2 quarts per 1000 miles which could lead to catastrophic engine failure at highway speed causing serious crash and loss of life. This is apparently a common defect with many hyundia engines that the manufacturer is actively trying to deny warranty claims.

The contact owns a 2019 Hyundai Tucson. The contact stated while driving at approximately 60 mph, the light oil low light illuminated and gray smoke started coming out of the front end of the vehicle, underneath the hood of the vehicle, and from the rear of the vehicle. There was a burning odor coming from the vehicle. The contact pulled over to the side of the road to inspect the vehicle. The contact found no visible failures; however, while attempting to restart the vehicle, the vehicle failed to start. The vehicle was towed to the dealer who diagnosed that the drain plug had backed out and needed to be replaced. The vehicle was not repaired. The dealer informed the contact that the engine needed to be replaced. The manufacturer was made aware of the failure and informed the contact that the failure might have happened during an oil change and the repair was not covered under warranty. The failure mileage was 50,000.
