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.

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.

Car caught fire on the expressway.

- Homestead, FL, USA

*Inside of car smelt like urine upon start. Car went into limp mode. First trip to dealership, catalytic converter was replaced. After the 6th time to dealership for same issue, manufacture approved engine replacement. car went into limp mode which posed a safety risk to our family as well as other vehicles on the road. This happened twice while on the freeway and we could have been rear-ended due to unexpected reduced speed. This also happened twice while turning with oncoming traffic approaching. problem was reproduced as this happened 6 times before the manufacture would approve an engine replacement. dealership replaced all the fuel injectors. No change engine went into limp mode P1326 (failure code). dealership installed a new short block engine. engine smelling like urine appears to be the first symptom (catalytic converter failure and replaced). When the car went into limp mode the engine light flashes. P1326 (failure code). Urine smell occurred beginning in July 2022 at (23,926 miles). Car went into limp mode for the first time on September 23 (approximately 25,400). * Another issue we are now addressing not related to the above engine issues: Car fish-tales when you drive over any bump in the road. dealership is replacing both rear shock absorbers. They said both shocks were leaking fluid. is very unstable and throws you around (like hydro-planning the pavement is dry). warning signs, just started happening.

2019 Hyundai Tucson I purchased 13 months ago with a mere 5, 241 miles on it., (Currently 29k mi) from Bert Ogden Subaru/Mazda in Edinburg, TX. On 6/26/22 it Started Shaking violently then "rodknocking" and finally failing in middle of major, high-traffic hwy. Near causing accident. NOwarning lights, check engine lights, oil lights, etc. Car was towed to Tipton Ford Hyundai, in Brownsville, TX. As it urns out (through my own research), my vin# falls under a recall issue that was not fixed prior to purchase nor disclosed to me, re:"engine monitoring and logics warning system failure". More importantly, 2) There are several class-action lawsuits underway, one settled, in which Hyundai was found liable for faulty "class II Theta Engines" and a suit involving "GDI NU 2.OL" (same as my vehicle) leading to rod knocking sensor failure, premature worn bearings and even cars catching fire! This is a no-brainer situation in which hyundai should be replacing my engine as ordered, but instead they are claiming, vehicle "neglect" (all maint. receipts were provided)and rejecting claim(which seems to be their m.o. based on similar complaints / civil filings that are ALL OVER THE WEB) and dealer says Im responsible for paying for new engine. Not sure who is responsible: the dealer I purchased from, for selling me a defective vehicle, the Hyundai dealer it was towed to, or Hyundai itself for denying what is a VERY well known liability on their part and apparently a widespread years-long issues with engine defects, recalls, suits, judgements, etx but have many court transcripts of consumers claiming Hyundai blaming thd customer for "neglect" to avoid replacing engine. I need legal help and advice. I HAVE to have car for work and dealer knows it and seems hyundai does, because they wont cover rental, wont provide "loaner" and seems dealer didnt even debate this with HMA because I purchased vehicle elsewhere. They just accepted Hyundai's denial and is now attempting to take advantage.

My 2019 Tucson has been getting horrible gas mileage and also making some strange noises that I'm unsure of what they are. It's also acting like it has no power installing on a pretty regular basis since the dealership has stated nothing's wrong with it and my vehicle health report continues to state nothing is wrong I decided to get a obd2 adapter to place on it so I could see what was happening. While the vehicle is running at idle doesn't matter if it is cold or warm the throttle body sensor does not go under a 10 so it's obviously sticking I don't know if it is defective or if it's been like that for some time but if the throttle body is stuck then that's going to cause it to stall that's going to make it burn more gas that's going to make it run pretty crappy and be kind of hit and miss. The vehicle's brakes are always grinding and squealing. There is also a wine and a tapping clicking sound coming from under the hood I don't know if it's a bad pulley or bearing or a loose heat shield or whatever but it's not injectors there's something under it. The rpms are continuously getting stuck the gauges are getting stuck, this car malfunctions every day.

When merging into interstate car is hesitating not picking up speed like it should. Cars merging behind me have to come around me and pass because I am not picking up speed fast enough.

When you step on the accelerator, sometimes the vehicle stops and takes a couple of seconds to continue running. I've faced a couple of instances were at a crossroad vehicles are coming towards me, and the car stalls and takes a while to start moving. I've been told by the mechanic car dealer that this is normal in this new accelerating system. It's can of scary and you need to accelerate and get stuck in the middle of the road. Mine is a Hyundai 2019 Tucson.

I purchased new 2019 Hyundai tuscan ultimate this May. In the first week the service engine light lid up. I took it to dealer and 2 days later the vehicle was returned as fixed. Based on dealer's resolutions it was evap leak code and they just had to replace the cap. Week later the sign came back again and I dropped off vehicle for another 4 days, dealer stated it was same code again and it wont happen again. I took it back and two week later the light came back on again and disappeared after three day. The fourth time light came back again and I will be dropping off the vehicle again. The dealer is still unable to find the cause and unable to fix the issue. Based on the discussion with service manager, it is minor problem for them but the issue is keep coming back and I have to keep beinging the vehicle back to the dealer to fix it.

Vehicle was in motion on I20/459 entry ramp in birmingham, al. Vehicle stopped and cut off completely in the middle of the busy interstate. Acceleration slowed until vehicle died and all error lights appeared and flashed on dash with a "service now" alert. Placed the vehicle in park, and turned the switch twice before it would crank again. Upon starting- the same "service now" light appeared and car was able to drive. "service now" light vanished about 10 seconds after vehicle was driving again.
