2019 Hyundai Tucson

My engine has been losing oil with no leak. 1st shut down was 02sensors crank shaft , check engine light still on took it fixed it not sure how. Brought it in for upgrade in security took it out and a week later didn't start. Now entire exhaust is gone it's still burning oil I called ciorperate because he would not acknowledge the burning oil. So we will start this every 1000 kile test x3 so it may be diagnosed but they still want ne to pay 2600 fix exhaust that is directly linked to sludge and burning oil!? I do nit know what to do but I have already put 1000s in fir service rental tow I literally cannot pay 2600 to get car back to prove the problem and eat it it isn't fair well jotting is but this has got to be illegal so ehow... I hope

The contact owns a 2019 Hyundai Tucson. The contact stated while driving approximately 30 MPH, the vehicle stalled. The contact stated that the vehicle lost power steering and brake functionality. The contact stated that the instrument panel went blank. The contact was able to restart the vehicle. The contact stated that the failure recurred. Additionally, the vehicle was hesitating and jerking while driving at various speeds. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the engine knock sensor software needed to be updated. The vehicle had been repaired. The contact stated that the failure had reoccurred. The manufacturer had not been informed of the failure. The failure mileage was approximately 62,000.

My engine light began blinking and the engine went into emergency mode on 3 separate occasions, and would not go over 40 mph; there was no prior warning. The first incident was in February of this year; the second was in April of this year, and the third occurrence was on 7/28. I purchased my car on 10/8/19 from Fred Beans Hyundai of Doylestown used, with about 12,000 miles on it. It now has 34,426 miles on it. I don't know what's causing the problem, and there haven't been any engine recalls. All the open recalls on it were serviced. When all the traffic around me is doing 60mph or better, this is hazardous stuff! My car has been towed to Fred Beans Hyundai of Langhorne for repair.

On Thursday, July6th 2023 for the 3rd time, the check engine light came on and the vehicle loses acceleration. My safety and others is at risk because it suddenly decelerates and is very likely to cause an accident.the car has been dropped off at dealer who told me they would “try” to look at it early next week. Its not been inspected by Police, Manufacturer or ins reps. The same problem occurred on Dec28 2022 and again in April of 2022. In Dec they replaced the “knock sensor”. In April the code had been cleared so the dealer said there was nothing they could do. Im in a rental vehicle now because the dealer did not have a loaner for me.

Knock Senser failed? On Dec 11, 2022 I was merging onto the highway at 530pm rush hour. I merged over one lane and the car made a loud noise and died. Cars flying past me on both sides dodging me in limp mode. I merged back to the right, there was no shoulder area available, so I coasted and finally came to a clearing on the side. I don't know how we didn't get hit. I ended up on a connecting road to another highway, and the Tow company couldn't find us because I didn't know where we were. It took about 3 hours of waiting for service. I had the Hazard lights on until the battery died. There was no warning except for the loud rattling noise and then boom. The car was towed to CHapman Hyundai in Phoenix, it has taken 5 months to get it repaired. I have 5 months of car rental bills and they still have not reimbursed me.

Oil consumption issues. No warnings of low oil until vehicle goes into limp mode and the check engine light flashes. Issue started in 8/22. I purchased the car used in 6/21. I have done 2 separate oil consumption tests. The last one concluded on June 21st, 2023. The dealership submitted information to Hyundai. Less than a week later, after the dealership filled the vehicle with oil, it is empty. No warnings. It was discovered because we have been checking the oil often. Vehicle has been towed to dealership 3 times since March. Vehicle currently at the dealership due to no oil.

On May 12 2023 I was driving my vehicle and heard a knocking sound that was unfamiliar. I pulled over and opened my hood and could hear the engine making a continuous knocking noise. I got back into my vehicle to take it to the closest mechanic and the vehicle failed after I had went barely a quarter of a mile. It took Hyundai almost 2.5 weeks to get an appointment with them and another week to have the car diagnosed. The service department called me and said the engine was bad and needed to be replaced. The car engine was still under warranty so my main concern was how long I had been without my vehicle and the rental car costs I was incurring. My vehicle was finally ready and fixed according to the service department. I went picked up my vehicle and started to drive home. As soon as I started to accelerate I noticed the car seemed to be delayed or was having difficulty accelerating. The ac also started hissing and blowing out hot air. I took the car back to the service department and had to wait another week. Finally get a call from Hyundai saying no issues were found and it passed all the tests. I go pick up the car and less then 24 hours later the car acceleration seems to be struggling and the car is having difficulty going past 50 mph. So now I’m back at square one taking my car that Hyundai says is fine back to Hyundai.

In June of 2023, my check engine light came on and my vehicle lost the ability to accelerate. I took it into the local Hyundai dealership who said it would take 3 months to look at and that this wasn’t a major issue. The car would not accelerate past 45 mph and could barely go up an incline. The dealership never even ran a diagnostic. I checked my oil dip stick and there was barely any oil on it. My vehicle isn’t due for an oil change until September. A local oil change business said I barely had one quart in the engine. They ran the codes and they came up as a P000B and a P1326. Dealership still hasn’t returned my call.

At approximately 69000 miles my engine stalled as I was pulling onto a highway and would not accelerate beyond a low mph. I turned back into gas station I had left and checked the oil. It did not register any oil and had a burning smell. There were never any dash lights indicating low oil. I put almost 2 quarts in vehicle. I then proceeded to drive as it seemed okay. I have had oil changes where the technicians have told me I was low on oil even though it was a normal time frame for oil change. I recently checked my oil just right as my oil change is due and the oil level did not register, nor were there any low oil indicators on dash. I had to add a quart of oil. This poses a hazard/safety problem. If not checked more often than normal, oil could go low and stall again. If pulling into a busy traffic area and a stall occurs, there could be an accident etc not to mention damage to the motor/engine itself. I have to frequently check the oil levels which should not have to happen for a vehicle with 70k+ miles.
