2019 Hyundai Tucson problems

Filed Nov 9, 2026 · Brakes, Electrical · GA

My husband was driving the car to work and all of a sudden a bunch of dash warning lights came on. It was lit up like a Christmas tree. Then the car went into limp mode. The vehicle has been at the dealership 4 weeks. And they refuse to do a 20 min test on the ABS module. It is a part of the HECU Settlement. You can find the settlement at [XXX] My husband is an electronic engineer. He knows why all the lights are on simultaneously. The ABS needs to be replaced. It's causing all the communication to go down that's on that can bus system. That's why all the parts dont make sense to each other. It all boils down to the ABS improperly working causing communication issues. The recall fix did fix the fires. It won't catch fire now but the ABS is still malfunctioning. There's a lawsuit. All vehicles involved in the recall are required a free ABS inspection and a replacement if they are malfunctioning but the dealership refuses to diagnose the ABS. That is the loophole Hyundai has found to not uphold the law. They are not standing by the settlement. They are skirting around from checking the ABS module so they won't find the malfunction. They want us to replace parts that are brand new that my husband just replaced. They want to charge us $700 for some other part and refuse to check the ABS system per the lawsuit. My husband needs that vehicle to work. So he's been out of work for 4 weeks. It's ridiculous! I can't hire a lawyer at this time and it's ridiculous that I may have to. This corporation should uphold their part of a lawsuit! There was already a settlement. My vehicle is included without even submitting a claim. It's ABS warranty is also extended per the lawsuit. I've read it backwards and forwards. I'm so at a loss! I need help. They also refuse to help us with a loaner and that will force us to drive an unsafe car in limp mode off the property when they are responsible for fixing this faulty part per the settlement INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

the federal safety agency Safety Complaint – 2019 Hyundai Tucson Engine Failure I am reporting a serious engine safety concern involving my 2019 Hyundai Tucson AWD 2.0L (VIN: [XXX]). On XXX, the red engine oil-pressure warning light suddenly illuminated while I was preparing to drive home. Concerned about possible engine failure, I stopped using the vehicle and had it towed to Pohanka Hyundai in [XXX]. On XXX, the dealership provided a diagnostic video indicating that the engine was defective and needed replacement. A written estimate dated XXX quoted $7,823.58 for an engine replacement. Despite this diagnosis, the dealership later declared the vehicle drivable and returned it after adding oil, without providing a satisfactory explanation for reversing its original findings. The engine problems continued, and the vehicle had to be returned to the dealership. This presents a serious potential safety hazard. An unresolved engine or oil-pressure problem could cause sudden engine failure, loss of propulsion, or a breakdown while driving on a highway or in heavy traffic, increasing the risk of a collision and injuries to occupants and other motorists. I am particularly concerned that a vehicle initially diagnosed as needing engine replacement was subsequently declared safe to drive without documented evidence that the underlying problem had been corrected. I request that the federal safety agency investigate whether this engine failure represents a broader safety defect affecting 2019 Hyundai Tucson vehicles and whether additional safety measures, including a recall investigation, are warranted. Vehicle: 2019 Hyundai Tucson AWD 2.0L VIN: [XXX] Mileage at diagnosis: Approximately 87,656 miles Incident Date: XXX INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving on the highway 65 mph in our 2019 Hyundai Tucson AWD, the vehicle suddenly experienced a severe power loss, loud engine knocking, engine light flashing, and the car in limp mode. This caused a terrifying hazard. We exited to safety, the car was towed and is at a Hyundai dealership. It pulled a diagnostic engine trouble code P1326 (Knock Sensor Detection System). The dealership confirmed the code, but is refusing to replace the engine under the Hyundai Engine II Class Action Settlement without an out-of-pocket 'combustion cleaning' fee, which, as seniors, we cannot afford on a fixed income. The dealership service manager told us that he requested Goodwill from Hyundai Corporate for the combustion engine cleaning. And because of a past denial, corporate denied it a 2nd time. So, we contacted our Hyundai Corporate case manager, who said our request for “the engine replacement” was still pending and in review by their team. She saw no denials, except for a loaner, which would be approved, upon repair approval. We added the dealership service manager on this call to discuss confusion about goodwill be denied by Corporate for the “combustion cleaning”. He said this case manager would not see the combustion cleaning requirement, because it was instructed by another department. His then pivoted the topic & said we received an estimate for combustion cleaning. My response “we never received an estimate & have no estimate in my email”. His response “I hate to use this word, but you’re a liar”. My husband then took the call saying “we did not receive an estimate in writing, although we had asked the tech for an estimate but nothing was final.” The service manager cut him off and said “we are done come pick up your car” & hung up. This dealership phone interaction needed to be included in this incident because now we are being put in grave danger as he is expecting us to pick up our un-drivable, unsafe & hazardous car with no concern for safety.

While driving at highway speeds, my 2019 Hyundai Tucson SE suddenly loses acceleration and drops into a 30 mph 'limp mode' while the engine overheats. This creates an immediate highway safety hazard with an imminent risk of a rear-end collision. The vehicle also suffers from excessive oil consumption, requiring manual top-offs twice a week. The servicing dealership diagnosed a fuel system failure, quoting $5,847 to replace the fuel pump, fuel injectors, and oil gasket. Hyundai Corporate (Case #43358088) officially denied warranty coverage on October 12, 2026, falsely claiming wear and tear despite active TXXM 150,000-mile extended warranty framework protections. Furthermore, there is a data discrepancy: the dealership pulled diagnostic trouble code P0172, but corporate claims the vehicle threw code P0173 and is withholding the physical diagnostic printout behind a fee paywall.

The new 2019 Hyundai Tucson equipped with the Nu2.0L GDI engine, I purchased in 1/2020 as the original owner to this day has been diagnosed with a burnt exhaust valve due to heavy oil consumption that has been an uncorrected documented manufacturer’s defect within Hyundai motor corporation. The excessive engine oil consumption has poisoned and destroyed the first catalytic converter, has fouled the combustion chamber which has consequently choked and burnt the exhaust valve with the excess oil ash and carbon buildup. The car was approved for a second catalytic converter install last week which my car currently sits at 125,000 miles and the dealership through the authority of approval with Hyundai motor America has replaced under warranty however subsequently running the excess consumption test, the car now has a burnt exhaust valve which Hyundai motor America is extending a “good faith” proposal which they are willing to replace 60% of the burnt valve and I’m responsible for the 40% even though I have complied fully with the dealership’s recommended preventive maintenance schedule which has been solely performed at the same dealership since the day I bought the car and drove off the lot up until the 100K mile warranty. And now discovering my particular motor has been extended to the 15/150,000 warranty due to the lawsuit settlement. I have continued with my diligence with keeping up with the oil, instead of ignoring the issue that the car burns excessive oil to potentially has the engine fail while driving to be fully covered on the rod bearing failure settlement. Help in my concerns would be greatly appreciated through the federal safety agency.

I have had 2 catalytic converters the original and a 2nd one. Now I need a 3rd due to excessive oil consumption. Corporate did a good will for a combustion cleaning and that did nothing. The dealership checked my oil and said there was excessive oil consumption and submitted for an engine replacement and it was rejected. Absolutely ridiculous.

I had bought my car in May of 2025 and within 12 hours of owning it. The check engine light came on. They replaced the sensor well. A couple days later, the check engine light came on again, and they had to rebuild my whole engine had the car for a month at this time. When they rebuilt the engine, they had the car for over a month. And ever since I got it back, it's always something the same thing has to get repaired. Well, I took it to the shop. Yesterday because it was misfiring, and I needed to have some spark plugs replaced, and they said that the Ignition coil needed to be replaced, but there was a recall on that not too long ago. And they fixed that on the recall. There's no reason that should have already went a few months later. Well, the problem is when I bought my car, I bought it from tar. Hyundai, it's now rusty, while it's Hyundai. They charged me $200 just to get my car out of their lot. Because I refused service because they were trying to charge me. $2500 to fix my car. Now mind you, I've already put over $4000 extra into this car. After purchasing it for over 21000 now they're not wanting to honor any work that Tara. Hyundai done because they don't be responsible. They don't want to honor the tar. Hyundai warranty or anything I've had it with this Hyundai company. I've been driving this lemon. It is yet again in the shop. Being fixed, although the engine was rebuilt a year ago, there is no reason. This car should keep having engine failure. They don't want to honor it. They don't want to give me a new car, they don't want to, they're acting like they don't care like, 00 well, it's your fault, but I did not buy the car, as is it came with a warranty. When they reserved my engine and had to rebuild it. They extended my warranty 2 hundred and fifty thousand miles

My 2019 Hyundai Tucson repeatedly shuts off while driving , without any warning. It rolls backwards while in park. The car could easily hit me taking things out of the trunk or hit my neighbors walking past my drive. The car has no power. It can’t get up to speed. It shakes and I have to get someone to add oil to it frequently. The first time this happened was in April of 2023. The engine seized up and it was towed to Driver’s Village in Cicero, NY. They replaced the engine block. But not the converter. Now, it is happening again. I have had 2 diagnostic tests done. One by my mechanic and the other by Advanced Auto Parts. Both tests say that the problem is the catalytic converter, but Hyundai refuses to fix the problem and will not honor my extended warranty. I have written and called them numerous times for almost 2 years now, about this and they say they will call me back, but they do not. None of the dealerships will even look at my car. I need someone to look at my vehicle. This vehicle is not safe. Other Tucson owners have the same problems with their cars, that I am complaining about. There is a federal emissions warranty that Hyundai claim they have never heard of, that would fix my car and make it safe to drive. I just want Hyundai to stand behind their warranty and fix my car before it kills someone.
