While driving the vehicle suddenly went into a limp mode and had a flashing check engine light. The vehicle was in limp mode for approximately a half mile prior to having complete engine failure and shutting off completely. Vehicle has always been properly maintained. Dealer confirmed engine is seized. A manufacturing defect with the Theta II engine caused the premature engine failure. If this occurred on a major highway myself and other motorists would be put at a significant risk as there was limited time to act and find a safe place to roll to a stop.
My husband had taken my vehicle to work one day. He called me and told me that the car had shut off and wouldn’t restart. He had just turned onto a major highway and was able to pull off to the side of the road. We thought it might have been the key fob, so I brought the other fob with me. Still nothing. The brakes were stiff and the dash would light up, but the engine wouldn’t turn over. We had the car towed back to our home. We replaced the battery and starter, and after doing research, have come to the conclusion there is something in the engine that is causing the engine to not turn over. We believe we’ve narrowed it to the timing chain. Our next step is to take it to the dealership and have it evaluated, but possibly looking to upgrade.
Even with have oil changes regularly and just about 2,000 miles ago *synthetic oil* the car started making very weird noises when accelerating and randomly having the oil light pop up. As I drove down the highway, with the pedal to the floor it would not speed up, the car then completely died and would not turn on. After having it towed and inspected they declared the engine was done and could not be fixed. They then informed me that because this issue is SO common it makes it extremely hard and expensive to find a replacement engine.
I was driving on the highway about 5 minutes away from home when I was avoid a reckless driver. (I called and reported it to the State police) Once I was trying to switch lanes my engine seized up in the middle of the highway. I keep up with the maintenance so I have no idea why it would do that. After getting towed and bringing it to the nearest dealership I was told my engine seized up and now I need to bring it to a Hyundai dealership to get it inspected before receiving service. I wont rice service until August 31st. This all new to me because my car fall in the recall of the many Hyundai's. How can I get rid of my vehicle as a second owner who bought t from a dealership? I don't feel comfortable or safe driving a vehicle like that.
Engine seized and needs to be replaced.
The contact owns a 2015 Hyundai Tucson. The contact stated while driving approximately 75 MPH, the vehicle decelerated to 35 MPH and began to jerk and shake. The contact pulled off of the highway as the engine seized. The contact stated that the check engine warning light was illuminated. The contact had the vehicle towed to a dealer where the vehicle was diagnosed with rod bearing failure. The dealer determined that the engine needed to be replaced. The vehicle had not been repaired. The contact researched online and related the failure to NHTSA Campaign Number: 21V727000 (Engine). The manufacturer had been informed of the failure. The failure mileage was approximately 108,000.
Driving down the street and the vehicle suddenly shut off in the middle of the roadway. Vehicle would not restart. Engine oil leaking out of tail pipe was noticed when vehicle was being placed on tow truck. Towed to Hyundai. They say seized engine and not covered under warranty due to low oil. No lights came on dash to include low oil or check engine. Only 66,000 miles. Oil last changed less than 4,000 miles. If there was no oil then how is it possible oil leaking from tail pipe. Looked at similar complaints. Appears rods and bearings are braking in these motors. 55 mph road when car suddenly shut off. Could have seriously injured driver. Could have caused serious accident. Hyundai does not stand by their product and warranty.
My engine just started making a really loud noise and I lost all power to it
The contact owns a 2015 Hyundai Tucson. The contact stated while driving approximately 50-55 MPH, he heard abnormal sounds coming from the engine. There was no warning light illuminated. The vehicle was taken to the dealer who informed the contact that the vehicle could not be repaired under an unknown recall as the VIN was not included. The contact stated that the failure reoccurred while driving. The vehicle was taken to an independent mechanic several times where it was diagnosed that the engine was consuming an excessive amount of engine oil. The independent mechanic advised the contact to bring the vehicle back after 1,000 miles. The vehicle was taken back to the independent mechanic where the failure was diagnosed as an engine combustion failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 126,000.
1. The engine lost oil without giving any warning. 2. Vehicle stopped in traffic and could not restart. 3. Yes (an independent service center). 4. Yes (others) the oil pump in the engine stopped working). 5. No warning light.
As part of Hyundai's class action lawsuit settlement, Hyundai promised to fix defective engines reporting the P136 error code and provide alternative transportation until the vehicle's defective engine is fixed. Instead I am without a car because Hyundai corporate claims they are "too busy" to fix it. For three weeks, Hyundai corporate has known that the engine of my 2015 Hyundai Tucson has reported the P1326 error code, and has been sitting at Key Hyundai at 4660 Southside BLVD; Jacksonville, Florida. Hyundai has refused to provide us with a loaner car, or authorize us to get a rental car, as required under the class action settlement, under the basis that the inspection has not yet been performed on the vehicle. When we asked for them to help find another dealership to inspect the vehicle, or any other assistance they could provide with alternative transportation, they refused. Hyundai assigned us a case manager, Ricardo (case number 19759747), who has repeatedly lied to us, and refuses to return our calls. For example, he claimed that he called the dealership to try to help us, even though the dealership reported no such call in their records and Hyundai confirmed that they did not have this call in their records. Hyundai refuses to assign anyone else to help with this matter. We have been calling Hyundai almost every day for three weeks and they have provided no assistance whatsoever. The constant theme has been to "sit and wait". I am requesting your office to help so that other Americans are not victimized by Hyundai. Hyundai promised to make the victims of their defective engines whole, and yet instead have vehicles subject to the class action lawsuit sitting around for weeks, and refuse to provide any assistance whatsoever with alternative transportation. Americans could lose their jobs and be forced into financial insolvency because of Hyundai not honoring their settlement agreement.
Driving on a 2 lane highway, engine shut off and left us stranded 2 hours from home. After the car being at the Hyundai dealer for a week, we get a text saying the engine had catastrophic failure. Internal bearing failure. Waiting to see if Hyundai with cover under 10yr/100,000 mile warranty. No light or anything came on prior to failure.
After inspection by the mechanic it was determined that the engine seized. The vehicle is currently at the garage and is available. At the time the engine seized we were on the highway with a speed limit of 70 mph. The vehicle shut off but luckily I was able to pull over safely onto the shoulder. I had my entire family in the vehicle so I definitely feel our safety was at risk. The vehicle has only been inspected by my mechanic. The oil was changed less than two months ago and was changed at regular intervals. There was no warning lights or messages prior to the vehicle losing power. Once it lost power the oil light and engine light came on.
The contact owns a 2015 Hyundai Tucson. The contact stated while driving 40 MPH, she noticed that the check engine warning light was illuminated. A few days later the contact was driving to take the vehicle to an independent mechanic when the vehicle loss motive power and stalled. The contact was able to get the vehicle to restart and get the vehicle slowly into a neighborhood where the vehicle stalled again. The contact had the vehicle towed to an independent mechanic to be diagnosed. The contact was informed that the engine seized and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 76,000.
My car Tucson is 2015 model. Since early 2018, RPM has risen while driving, cars have been shaken, and engine check lights have continued to come in. When I went to the car repair shop and checked, my car said it was an engine piston defect. And engine oil also disappears 500 to 1,000 miles after replenishment. So I have to make up for it regularly. I'm very nervous about the car, so I have to turn on the engine before departure and leave after 5 minutes, and I have a lot of inconvenience due to this and that problems. I want to know more about what my car is like and I desperately need your help.
On April 16, 2021 my husband was driving our 2015 Hyundai Tucson home from work at 10:30pm. Upon entering Interstate 77 S the Tucson suddenly came to a complete stop. He was able to get it off the side of the interstate. There were no dash lights that came on or noises to give warning this was about to happen. We had not had any issues with the vehicle till then. We had the Tucson towed to the car lot where we had purchased it on 12.26.2020. This could have caused accidents that could have harmed not only my husband but others traveling that interstate that night. Other than the mechanics that replaced the engine and an individual from Warranty Solutions no one else inspected the blown engine. We spent $6948.55 for a rebuilt engine and labor. We were without our vehicle from 04.16.2021 until 08.28.2021. Hyundai had a recall on engine components but for some reason ours was NOT included. I strongly feel it should have been. Not only did this failure put my husband in danger but also anyone traveling that interstate that night.
I purchased this vehicle after it had been leased. I purchased it with 48K miles in December 2018. I have maintained the vehicle, per the manufacturer's guidelines. In July 2021,at 69K miles, a high-pitched whirring sound came from engine when gas was applied. The noise did not occur when vehicle is in idle. The noise came suddenly when I was accelerating getting on a highway (on ramp). I took to my trusted mechanic immediately and they haven't been able to diagnose the issue at this time. However, they found busted metal pieces in the pan and have ruled out more common issues, like serpentine belt, timing belts, and exhaust. My mechanic was so far into the engine trying to find the clearly broken part (or parts), that it will be more cost effective to just replace the engine. I contacted my local Hyundai dealership, and they ignored my emails (until this point). A safety concern is that the car could still be driven, even though there was clearly something wrong with the engine. There were no warning lights of any kind in the dash, before or after the engine sound came on. Also, a qualified mechanic could not find/replace the broken part, and Hyundai is ignoring my engine issue requests. I also contacted Hyundai USA and am waiting for a response. The vehicle's engine, if defective, is out of warranty because I am second owner. The second owner warranty only lasts to 60K miles.
Engine failure. I changed car oil and filter every 3,000 miles. A strong noise came from the engine and Pep Boys mechanic say I needs oil. I changed oil ,drove one mile and the car stop.
Engine seized, yes available for inspection, no prior warning lamps, messages or symptoms, car just stopped. Fortunately this happened on a backroad and not on interstate 95 between home and school. Manufacture said they would not help, seized engine determined by mechanic, no oil. Car maintained as recommended by manufacturer. I'm now finding out this is a common problem with this make and model, it burns oil and engines seize. Who allows cars to be on the road that seize up!!!
ENGINE SUDDENLY FAILED. STARTING ALL WITH A RATTLING SOUND ONE NIGHT WHILE DRIVING. THR NEXT DAY, DROPPED MY CHILD OFF AND CAR JUST CUT OFF WHILE DRIVING IN MY APARTMENT LOT. THE CAR WAS IN DRIVE AND MY FOOT WAS ON THE GAS WHEN IT JUST SHUT OFF.
The vehicle suddenly reduced power on 05/27/2021 while my 82-year old mother was driving home. When I checked the car, the check engine light was blinking. I Immediately took to a service center and noticed the same low power 'limping' performance and a knocking sound (previously unheard). On Friday, 05/28/2021, the service manager provided an update: that they found Diagnostic trouble code p1326 related to engine inspection. Performed oil change. Cleared the diagnostic code. Ran the engine. Could hear an internal knock at higher RPMs. Will need engine replaced or rebuilt. No parts are available to replace or rebuild at this time. They contacted Hyundai with the VIN who said the vehicle was out of warranty (110,000 miles). Drove the vehicle home (two blocks) at low RPMs with no issue. There was no previous indication there was any potential issue with the engine. Maintenance and oil changes have been completed on a regular basis. There were 600+ miles before the next 5,000-mile oil change was due. Drove the car the next morning, Saturday, 05/29/2021, to see about trading the car in at the local Hyundai dealer (5.1 miles away) before the situation got worse and purchase a new vehicle. I was expecting the car would be drivable - at least at lower RPMs. The car immediately began to lose power, the check engine light began blinking and stalled three times in traffic before crawling onto the dealer's lot. They had a mechanic look at the vehicle, said the engine was shot and offered $250 as all they could do was junk it since engine parts were scarce and it would not be cost-effective to replace the engine even though the body was in good shape. I felt I had no choice but to accept as it was now clear the vehicle was unsafe to drive. For the engine to die within about 15 miles of the initial onset without warning and the sudden loss of power, is a dangerous situation is this is waiting to happen to other vehicles.
I was driving down the road when suddenly the car started rattling. The oil light blinked on then off. The engine then made a squealing noise, the battery light came on, and then the engine froze. The accelerator pedal and the steering wheel were stuck. I turned the car off, but it wouldn’t restart. Thankfully, I was on a quiet neighborhood street and not in the middle of a busy highway when this happened. I had it towed to the dealer, who inspected it and stated that I needed to have the entire engine replaced. I then had it towed to another dealer for a second opinion, but they also said the engine needs to be replaced. Unfortunately, since I am not the original owner, Hyundai claims the 100,000 mile powertrain warranty does not apply, even though the car only has 85k miles.
At 40,000 miles with no warning engine stalled while driving Upon inspection by dealership Bore Scope Scarring on all cyl walls predominate on 1 and 2 rf suspects lower engine issue Oil change records were provided
DRIVING ON THE FREEWAY AT 70 MPH DURING 5:15 RUSH HOUR TRAFFIC, THE ENGINE STOPPED RUNNING. THERE WAS NO COMBUSTION, BUT THE BATTERY WAS STILL WORKING. WHEN I HAD IT TOWED TO THE DEALER, THEY SAID THE ENGINE HAD LOST COMPRESSION AND COMBUSTION AND NEEDED TO BE COMPLETELY REPLACED. THE CAR STOPPING IN THE MIDDLE OF THE FREEWAY DURING RUSH HOUR COULD HAVE CAUSED A SERIOUS ACCIDENT.
ACCORDING TO AN ATTORNEY MU ENGINE IS A NU ENGINE. AS FAR AS I KNOW NO RECALLS OR LAWSUITS ARE PENDING. CAR WAS DRIVING FINE, LOST ALL POWER TO A VERY SLOW CREEP, MAKING A VERY STRANGE SOUND IN ENGINE, FRIED STARTER AND NOW WON'T WORK AT ALL. EVERYTHING PEOPLE SAY THE THETA II ENGINE COMPLAINTS HAVE BEEN WE ARE EXPERIENCING WITH THIS CAR...BUT IT HAS NOT BEEN RECALLED. WE HAVE NOTICED EXTRA OIL CONSUMPTION BUT FIGURED DUE TO HIGH MILEAGE. WE HAD A MECHANIC COME OUT AND HE SAID THE THINKS THE ENGINE IS FRIED OR THERE IS SERIOUS PROBLEMS. THIS VEHICLE IS ONLY 6 YEARS OLD. THIS ALL DURING COVID, MY HUSBAND IS HIGH RISK WE HAD TO GO BUY ANOTHER CAR AS WE DO NOT HAVE MONEY TO FIX. I NOW HAVE 2 HEFTY CAR PAYMENTS WITH 1 VEHICLE WORKING. I NEED HELP TO KNOW IF THIS ENGINE DISPLAYING ALL THE SAME PROBLEMS WILL TOO BE RECALLED .
