Powertrain issue. Multiple times the after stopping the engine revs for a few seconds and then the vehicle will lurch forward. It acts like the CVT transmission has a delayed response to the accelerator. The condition comes and goes and sometimes it happens multiple times in the same trip.

Driving down the road, accelerated to speed limit, but the car slowed down and the RPM's stayed at 2000. The car just stopped running and I was able to pull over into the middle lane. Towed to dealership, 6 weeks min. to diagnose until we know what happened. DANGEROUS!!!

my 2018 Hyundai Tucson starting having lurching issues on when first started. i have to back into my driveway so i dont have to go in reverse then go forward. it jerks back and forth so hard. It finally took its toll on the transfer case and it exploded internally. the Dealership said they had never seen this before. i was hoping that was the cause of the issue but it wasnt. Still doing it and am afraid it will do it again. i was under warranty when it happened, so teh $2000 replair was covered. i'm concerned it will happen again. teh problem goes away after it's been completely warmed up. but like many others, its a scary issue when first started. it also will also shift hard when it firsts get's going (after the initial hard lurching back and forth). i dont know what to do. Love the car otherwise, but concerned with ever buying a Hyundai again.

The contact owned a 2018 Hyundai Tucson. The contact stated that while driving up a hill at 30 MPH, she heard an abnormal popping noise emitting from underneath the vehicle without warning. Upon inspection of the vehicle, the contact saw that a fire had started from underneath the front passenger side of the vehicle. The vehicle in front of hers witnessed the fire and assisted with calling the authorities to the scene. Both the fire and the police department arrived as the fire department extinguished the fire. Both a police and fire report were filed; no injuries were reported. The contact had the vehicle towed to an independent tow yard where it was deemed a total loss. Upon investigation, the contact linked her failure to NHTSA Campaign Number: 20V543000(SERVICE BRAKES, HYDRAULIC); however, the cause of the fire had yet to be determined. Both the dealer and the manufacturer were notified of the failure. The vehicle had been destroyed. The failure mileage was unknown.

Catastrophic engine failure due to loss of oil pressure without warning at highway speeds. Traveling approximately 70mph on the freeway. Engine develops a rapid knock in sync with engine RPM's and immediate loss of power. At the same moment, I exited the freeway. As I left off the accelerator to apply the brake, the engine stalls completely. Once stopped, I checked the engine oil, which was within specifications. Had vehicle towed to a mechanic and diagnosed as engine failure due to loss of oil pressure. Before this, the engine regularly consumed 2-3 quarts of oil per oil change starting at approximately 45,000 miles. Catalytic convertor has been replaced once due to being plugged by consumed oil. Hyundai fails to remedy.

My engine has locked up on me and stalled because of water in the oil. I was never informed about this -??knock sensor-?? update for Hyundai that would have prevented all this in the first place. I-??ve had to come out of pocket for 2 tow trips and loaner car all while my vehicle is under 5 year/ or 60,000 mile warranty!! Now this apparent -??America-??s best warranty-?? local dealership is trying to tell me that my repairs are not covered under the warranty and I would have to pay $10,000 out of pocket for the repairs! This is going on 3 months now and still no one has contacted me and no one is helping me. That vehicle is my ONLY source of transportation to and from work an hour away! I am unsatisfied with my Hyundai Tucson and the false advertisement for claiming to be -??America-??s best warranty-?? and for not providing a safe reliable vehicle like Hyundai promises!

A connecting rod bearing was thrown through the engine block causing it to stall out on the freeway. This is exactly what is occurring with vehicles in the Theta Class Action Settlement but the company states my VIN number is not included.

Rod bearing failure. Sounded like a tractor all of a sudden and stalled every time I-??d come to a stop. Had it towed to the dealership. Awaiting word from Hyundai as to whether the warranty will cover this. Checked oil and wasn-??t low. No check engine lights or oil lights or anything ever came on. No noises prior to this happening. Kept up on routine maintenance.

I bought my 2018 tuscon one year ago in June 2020. 70,000 miles on it now, regular maintenance. No warning lights, everything was running OK. I started experiencing hesitation taking off then lunging when stopped in the last few months. Now I'm sitting in the driveway because it won't start. Realized oil was low which is odd because I've noticed it's been burning more than previous but no more than a quart so it's not like it was dry. I'm supposed to be able to get 5k on an oil change now adays but starts running poorly if it's not changed by 3k. Needless to say iadded qt of oil I was going to get oil changed yesterday but wouldn't start. I changed the battery, still won't start, starter was tested good, fuses all in tack, changed camshaft sensors at 90 dollars a piece still nothing. Check alternator that's fine. It clicks one time but have all lights power everywhere it should. In 2 days I've spent 215 on a battery, 200 with tax on sensors, 50 code reader no code by the way. Did have p0014 which indicated need for either oil change or camshaft sensor. Nothing. I'm a sitting duck and all the things I've experience are what they experienced in the theta engines like hesitated, burning oil, ticking sounds, lunging etc. GDI isn't any better. I hate this car. After this one is paid off and I guess put a new engine in I'll be getting rid of it. Going back to a solid Buick. I'll never buy another hyundai. This is the second vehicle with engine problems we bought. Not to mention the risk of for but hyundai near me hasn't been able to get the parts for over a year. I'm currently in a wait list.

Buy brand new off lot. Never miss Regular maintenance on engine oil and filters. Car had only 55200 miles. After 500 miles regular oil interval maintenance. Car underbody show no oil leaks anywhere on 12/05/2021 park on driveway. This morning Car not start without oil indicator or engine light warning comes up. Open hood up, check oil dip stick show no oil residue. Yike, where is low oil warning light sensor when no oil in engine. Apparently it not working or never have it on in my opinion. Gotta be recall issue for this. So I ran to Walmart get a quart of sythenic oil recommended and fill it up. Car start up find and drive ok for now. Not sure in future. This is a must recall on No Oil Indicator Sensor Malfunction!!!!!!!!!

Purchased new on 5/30/2018. 3/2021 I noticed shaking, noises, pinging, whining sounds and vibration coming from engine as I turn engine on / off and in drive. 3/24/2021 I brought vehicle for inspection. Service Advisor felt the shaking, vibrations and heard the pinging / noises and whining sounds as I turned the vehicle off. Vehicle went for oil change and inspection, stayed overnight and no fault found, service bay stated they could not reproduce the occurrence. The sensations worsened and I brought vehicle back on 3/30/2021 for inspection as I did not feel safe driving vehicle. 4/02/2021 dealer said the sensations could not be detectable and it was suggested that maybe the Turbo dual clutch engine. 10/15/2021 the air conditioner failed. Brought vehicle in for inspection. Service performed diagnostic testing on vehicle and found internal failure on a/c compressor. New compressor was ordered and replaced. Replacement air conditioner is not as powerful or cold as original part. Vehicle is still making pinging, whining, vibrations. 11/29/2021, engine light came on. I reversed out of a parking spot and it felt different. Put gear in drive and immediately the gas pedal went to half way to floor and the vehicle jerked and then seemed to catch the gear. Then the pedal went to the floor and there was no go, then it kicked in. Repeated multiple times. Tried reverse and there was none. No rpm movement and quickly came a strong burning smell. Had vehicle towed dealer. All vehicle services are current and up to date.

My engine blew on the freeway. And we believe it to be a rod bearing issue. Regular oil changes and maintenance done since I owned it. It is currently at the dealership awaiting to hopefully be repaired through extended warranty. The service lot was filled with Tucson's and the service repair man said it was the same issue in all of them. This is a major safety concern as engine failure anywhere on the road can lead to accidents and stalling vehicles. Upon the engine failure, there were no engine lights or any signs that this was going to happen. My car stopped accelerating so I began to pull over and before I could get fully over, all of the engine lights started flashing and the engine began smoking. I just don't want this to continue to happen as this is clearly an ongoing issue, there was a recall with the rod bearing in the 2017 2.0 model, which is my model but being a 2018. I appreciate your time in reviewing this and hope it catches some attention.

With 2018, Hyundai Tucson, I was accelerating on the highway coming off of an exit ramp. I was on my way to the dealership to investigate a knocking sound I just started hearing with the engine. Suddenly, the engine failed completely and I started to smell burning. I was able to roll into the shoulder and have my car towed to the dealership. An engine light came on a few miles before the engine failed, but I had no warnings at the start of the trip. Car was at 60,000 miles.
