2020 HYUNDAI TUCSON Recalls, Complaints & Safety

ABOUT 18 MONTHS AGO, SOON AFTER AN OIL CHANGE AT THE DEALERSHIP, I CHECKED THE DIPSTICK. IT SHOWED LOW OIL AND I ADDED SOME. IT MADE ME THINK THAT THE DEALER HAD SHORTED THE OIL. NEXT OIL CHANGE, I HAD THEM SHOW ME THE OIL WAS FULL. IT SHOWED LOW FULL. I'VE BEEN CAREFULLY CHECKING THE OIL EVER SINCE AND HAVE CONTINUED ADDING OIL IN BETWEEN OIL CHANGES. 8 OR SO MONTHS AGO, I HAD THE OIL AND FILTER CHANGED. I MENTIONED THE PROBLEM TO THE MECHANIC AND HE SAID HE WAS AWARE HYUNDAI'S LOSE OIL. SINCE THEN, I HAVE CONTINUED TO ADD A HALF QUART AT LEAST ONCE A MONTH. I PARK ON CONCRETE AND THERE IS NO SIGN OF LEAKING OIL. I STARTED RESEARCHING THIS ISSUE AND FIND IT IS AN ONGOING PROBLEM WITH 2020 TUCSONS. I AM VERY CONCERNED WITH ENGINE DETERIORATION, SAFETY AND OIL LOSS.

My car has been burning through about 2 quarts of oil every 1000 miles. Hyundai will NOT replace the engine. If this continues My engine could malfunction while driving. This is a serious safety concern and there's plenty of information on it. They refuse to recall it.

Complete engine failure. Car was burning oil, wasn't aware. Since I am an on the road salesman I travel alot and get oil changes consistently. Then recently the engine oil light keeps coming on when rounding bends or stopping on a hill. I checked the dip stick and see oil is Half gone in between oil changes. The car stalled as I was approaching a dangerous intersection. Thankfully I was able to stop the car.

burning oil at a rate of 2 qts per 1000 miles driven. Known issue in these models of tucsons. Not covered by the class action lawsuit as this VIN was not identified. It is burning oil at a catastrophic rate. The problem has burned through multiple catalytic converters that were covered under the warranty but did not solve the underlying problem. Has been burning oil since owning the car a year ago.

I have a 2020 Tucson Sport with 82k miles. Since new, it consumes 1US qt. of oil every 6 month, although I religiously do the tune-up on its recommended intervals using only Mobil 5w-20 synthetic oil. What can I do?

Component: Engine / Electrical System / Fuel System Incident Date: February 9th, 2026 Vehicle Speed: 45-50 MPH Description: While traveling at highway speeds on a major roadway, the vehicle experienced a catastrophic and sudden engine stall without any prior warning or dashboard indicators. The engine shut off completely while in motion, resulting in an immediate and total loss of power steering and power-assisted braking. I was forced to perform a high-effort emergency maneuver in heavy traffic to reach the shoulder and avoid a collision. This vehicle is used to transport myself, my coworker and my family whose lives was placed in immediate danger by this failure. Since the start of the financing agreement, this vehicle has a documented history of recurring sensor issues and failed repair attempts at the dealership (Route 1 Hyundai). The dealership has previously attempted to address electrical/sensor malfunctions, but the root cause remains unresolved, leading to this life-threatening stall. I believe this is a significant safety defect in the vehicle’s electrical or fuel management system that poses an unreasonable risk of accidents and injury.

This engine has 70,000 miles on it and has burned a quart of oil every 2500 to 3000 miles, two full quarts between oil changes. In talking to others Hyundai owners, they have similar issues. I have owned multiple other brands of vehicles with well over 150K miles and they did not burn any oil. Fords, BMWs, Volvos, and Subarus.

2020 HYUNDAI Tucson Engine blown @ 89,307 miles and 1,265 miles after oil change due to missing oil plug. Daughter drives about 5 miles per day for college and groceries. The day before Thanksgiving 2025, her 2020 HYUNDAI Tucson died about 48 miles down the Highway without warning, no prior warning lights or sounds before shutting down. I had the car towed to the local HYUNDAI dealer in the town where her college is, where they told us the engine was totaled due to a lack of oil and a missing oil plug. I discussed with the HYUNDAI service advisor about having an extended warranty; however, they would not work with me or the company I had the extended warranty with, mentioning they would not cover the engine failure due to the oil plug being missing. I asked the service advisor in a separate conversation whether an oil pan drain plug that was not properly torqued during an oil change could remain in place for some time—particularly during short, low-speed driving—and then gradually work loose over additional miles. The service advisor mentioned that in situations like my daughter’s, where only about 1,265 miles were driven after the oil change (mostly short trips), it would be within reason for an improperly installed drain plug to stay in place until a longer highway drive with higher RPMs, at which point it could back out completely and result in a sudden oil loss and engine shutdown. The service advisor also mentioned that this is something they had seen before and is not unheard of on these vehicles.

The car has been burning oil for about two years . Noticed when my oil was changed by my mechanic , he told me oil level was about a quart low . Since that time I have had to add oil every 1000 miles . Approximately 4 quarts between oil changes , which I have done every 5 to 6 thousand miles . I have read that many other people have had same problem. This is a 2020 Tucson, Unlimited Model . Which at the time of purchase was the top model Tucson on the lot . Hopefully this is enough information to help get the consumer some Help in this situation ! Thanks

On December 27, 2025, while driving, the engine suddenly lost power and the vehicle entered limp mode and became undriveable. A warning light appeared and diagnostic code P1326 was later confirmed, indicating engine bearing failure. The vehicle could not be driven safely and required towing to a Hyundai dealership the following day. The engine failure caused a loss of propulsion safety risk. The vehicle remains out of service pending a full engine replacement. The vehicle is available for inspection at a Hyundai dealership.

I have experienced 4 repeated issues within 4 months with my vehicle. Starting in September 2025 and the 4th and current issue today 1/12/26. Driving when all of a sudden all of my brake components lamps come on dash oard, forward collision alert, and check engine, my vehicle struggles to accelerate accurately. Blue Link diagnostic throws various codes such as ECM, Transmission Control System, even "multiple possible issues". Each time my vehicle has been at Hyundai dealership for repair. Each time they repair something different 1st- replace ABS module and hydraulic brake, 2nd - happened out of state at my mother funeral and replaced my ECM, 3rd couldn't figure it out and guessed it was my Forward collision camera and replaced it, 4th - is today and awaiting dealership diagnosis. This issue has left me stranded several times local and long distance, occured in middle of driving including on highway, and overall uncertain of the safety and reliability of the vehicle as each time it has been the same type of issue. I have been in communication with Hyundai Corporate since October and they stated that even tho I only have 24k miles on the vehicle that it is outside the state of IN lemon laws for a buyback. If I hadn't purchased an extended warranty I would be in even more debt or unable to put it in the shop even tho I don't feel like this should be my burden when I have kept this vehicle in great shape, low mileage, frequent oil changes, etc . however the safety of my vehicles goes unresolved. At this point I am uncertain that Hyundai is properly diagnosing my vehicle and not certain how these issues are impacting other components of my vehicle such as brakes, transmission, engine, sensors. I am the only owner of this vehicle bought brand new. I have checked repeatedly for any recalls that I have not addressed and at this time none are pending. I fear that this vehicle will continue to have more safety issues.

The contact owns a 2020 Hyundai Tucson. The contact stated that the engine was consuming an excessive amount of engine oil. The vehicle was taken to the dealer, and the oil level was topped off. The dealer requested that the contact return every 1,000 miles for inspection. The failure persisted, and the vehicle was returned to the dealer every 1,000 miles. The check engine warning light was illuminated. The vehicle was taken back to the dealer for an inspection, and the dealer discovered that the catalytic converter was defective and needed to be replaced. The vehicle was taken to an independent mechanic for a second opinion, and the contact was informed that the engine had failed due to a defect in one of the engine cylinders. The dealer was informed of the findings by the independent mechanic, and an appointment was scheduled to inspect the vehicle. The vehicle was not repaired. The failure mileage was unknown.

The rear self leveling shocks are worn out. The car bounces terribly and control is an issue. I have confirmation from the dealer that the shocks need to be replaced. There were no warnings that the parts were broken.

Spark plugs have been replaced twice- fuel injectors cleaned and now I have another misfire in cylinder 3 and have to replace all four fuel injectors.

Vehicle excessively burns oil, engine drives rough, exhaust developed smoke, burnt smell in engine, engine and oil gauge light comes on.

the engine failed without warning. While going up a hill the car lost power. Yes, the dealership said it was a known problem. Yes, the dealership fixed the problem by putting in a new engine which I was responsible for 5% of the cost which was 739.66. The only warning that was given was after the car failed, the engine light and the oil light went on.

The contact owns a 2020 Hyundai Tucson. The contact stated that the vehicle unintendedly shut off while driving. The vehicle was restarted. There were no warning lights illuminated. The local dealer was contacted and scheduled an appointment. The vehicle was not yet diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 70,000.

My adult son was driving and under the hood started to smoke. He pulled over and opened the hood to take a look and then a fire started under the hood! The fire department was called and they put out the fire, cut the gasoline and duct taped it up so the fuel line would not further ignite the hot engine. My insurance is looking into what would have caused a random under the hood fire. Luckily no one was injured. However the engine section of the car is melted beyond belief. My insurance has not told me if the car is repairable or not.

The contact owns a 2020 Hyundai Tucson. The contact stated that upon starting the vehicle, the Brake Auto Hold was engaged unintendedly and failed to disengage upon pressing the button, which required the contact to turn off, restart, and drive the vehicle for some time for the Brake Auto Hold to disengage. The contact stated that the failure had been recurring. The contact stated that the infotainment system was inoperable. Additionally, the passenger's side rear seat belt failed to buckle as intended, and the passenger's side rear door handle fractured while the contact was opening the door. The dealer and the manufacturer were not notified of the failure. The vehicle was not diagnosed or repaired. The failure mileage was approximately 102,000.

My engine is burning excessive amounts of oil, which is a "known issue" of Hyundai Tucsons. After an oil change with full synthetic oil, I cannot drive my vehicle more than 4,000 miles without reaching dangerously low oil levels. Most importantly, there is no clear indicator of this low oil level—no light that comes on and STAYS on to tell me as the driver to check the oil and see if there is a problem. Instead, if I brake too hard or take a turn to sharply a red oil light will turn on for 1-2 seconds and then turn off again. It is easy to miss. The first few times this happened in May I thought perhaps there was a loose wire on the sensor. After it appeared 3 or 4 times I took it to a mechanic who told me the oil level was so low that they had to add 2 quarts of oil just to have it register on the dip stick. The excessive oil burning is a known issue that Hyundai fights tooth and nail to avoid correcting. But to not have a warning indicator that the oil is at a dangerously low level is reckless on Hyundai's part. The engine could have seized up, thrown a rod, or any number of consequences. I had my oil replaced by Hyundai in May as part 1 of their oil consumption test. My car passed their 1000-mile test and 4,000 miles later I was in dangerously low oil territory again. Thankfully, I knew what to look for this time. Cars should not consume oil at this rapid of a rate but even if they do drivers should be notified about low oil levels via car sensors to keep them and their passengers safe.

Car was fine and I get regular oil changes. Last week all the sudden the car started making noise and just shut off. When my husband checked there was no oil on the dipstick but I park on concrete and the car is not leaking oil. Apparently the motor is blown and completely locked up.

High oil consumption leading to costly repairs outside of warranty.

Vehicle is burning an extreme amount of oil between regular oil changes. We are having no help from our local dealership in Tuscaloosa, AL where we purchased the car to resolve this issue without first spending a lot of money to diagnose an issue we certainly already have. Long before it was due for routine oil change, we checked it and it was COMPLETELY EMPTY of oil. NOTHING IN IT. We have to put oil in it three times before its next routine service. We have always had the vehicle serviced, on schedule, by our local Hyundai dealership and are the only owners of the car.

The contact owns a 2020 Hyundai Tucson. The contact stated that while driving at an undisclosed speed, the low oil warning light briefly illuminated. Upon inspecting the vehicle, the contact noticed that the engine oil level was low. The vehicle was taken to the dealer, where the contact was informed that the engine was not consuming oil and that an oil change was needed. The dealer advised the contact to return after 1,000 miles to inspect the oil level. The vehicle was taken back to the dealer; however, it was not diagnosed or repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 72,000.

In between my last 3 oil changes I have “lost” all of my oil in my car. Checked my oil randomly and there was NO OIL at all on the stick. After this last change I have checked it every week. I did not check for 2 weeks less than 1,000miles and it was below the low on the mark. Obviously running out of oil while driving is not safe and can cause the engine to blow. This can cause a crash or fire. There have been numerous issues with this and the cars need recalled. This is ridiculous.

Engine oil excessive consumption/burning oil

the car started using a little oil around 80,000 mile, and its just gotten worst , to the point that's it using 1 quart per 150 miles the car runs ok but its ridiculous the amount it is using. and from what I've found researching there is a lot of complaints

Engine run hot smoke from engine car cut off wouldn't restart had totaled to Hyundai company in Lithia Springs Ga was told by service guy that engine locked motor needed replaced. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Heavy oil consumption problem - burns through oil completely every 300 miles. Replaced catalytic converter once already.

Was told by dealership that forward camera assist is not functioning, but could not tell me why it failed all of a sudden. No accidents. $1586 to repair because no longer under warranty. Vehicle is only 5 years old.

MOTOR IS CONSUMING A LOT OF OIL. I need to CHANGE EVERY month, which IS VERY EXPENSIVE

When driving my check engine light started to blink and my car would not accelerate. I made it home and plugged in a diagnostic reader and got the code P1326 glow relay short circuit. My car along with my friends 2021 Hyundai Tucson both have this same issue. There needs to be a recall for these years. There is a recall out for this specific problem in sonatas and Tucsons and need to cover these years as well.

Excessive oil consumption. Confirmed by Strickland service centers on last 2 oil changes. Engine is at risk of failure if oil level drops.

Car is burning through oil at a rate of 5L per week.

Car broke down first time about 2.5 months ago. It was towed to Fred Beans Hyundai of Doylestown PA and they did oil testing on it and I was told that the car was burning oil too fast. They told me under warranty they needed to do a carbon combustion cleaning. So that was down, and less than 24 hours of having the car back, the check engine light came back on, the car wouldn’t drive above 50 miles per hour, and was jumping forward (the same thing that happened the first time) I had the car towed back to the dealership and they told me there was still leftover carbon and it needed to cleaned out again. The car was fine for about 2 months, however just today it broke down again. Same problem, check engine light came on and started flashing, the car will not go above 50 MPH and it jumps forward. I have now been given back a car that is unsafe to drive and put my family and 2 times. Clearly the dealership is not fixing the actual problem at hand and continues to put my family and i’s safety at risk. Each time the car has broken down I have been on the pa turnpike and been put in an extremely dangerous situation.

The contact owns a 2020 Hyundai Tucson. The contact stated that the "Check Brake Light" message was displayed on the instrument panel, and the screen indicated that the rear brake light bulb was defective. The vehicle was initially taken to an independent mechanic where the brake light bulb was replaced; however, the failure recurred. The vehicle was then taken to a dealer where the contact was informed that the brake light bulb had failed because the bulb was an aftermarket part. The contact had the brake light bulb replaced with an authorized Hyundai part; however, that part also failed soon after the bulb was replaced. The manufacturer was notified of the failure and referred the contact back to the dealer for assistance. The vehicle was taken back to the dealer but was not yet repaired. The failure mileage was approximately 40,000.
