2019 Hyundai Tucson

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.

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

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!
