I was driving on the freeway and all the sudden the check engine light started flashing. At the same time the engine slowed down and would not accelerate past 60 mph. I took the first freeway exit and drove to the nearest auto parts store. The store clerk hooked up a code reader and it came back with a P1326 code, Power Train System. Is it a real problem or just another bad sensor?

On January 6, 2023, I was driving on the interstate when suddenly the engine started vibrating, the check engine light came on, and I lost engine power. As I was in the left lane of a multilane interstate, I had to negotiate getting over to the right emergency lane. Because of the loss of power, I felt like this put me in a dangerous situation. Anyway, once I got pulled over, I had the vehicle towed to a Hyundai dealership. After diagnosing the vehicle, they say the vehicle needs a new engine. The vehicle had been consuming excessive oil since I purchased the vehicle in 2018 and has been getting progressively worse. At the time of the engine failure, it was burning about 1 quart of oil every 1000 miles. The dealership tried getting HMA to cover the engine replacement cost even though the vehicle was out of warranty but was denied. I've uploaded a picture of the technician's diagnosis and HMA's response to request for engine replacement coverage.

My car has 113,000 miles and the engine went out going down the highway with my young daughter in the car. This could have been a disaster if someone would have been behind us. After researching about my issues I found almost all their motors are going out or catching fire. Someone needs to hold them accountable. My car has been in the shop for weeks now with no approval from Hyundai. My daughter almost died last year in a car wreck. What if someone-??s engine goes out with someone behind them. Someone could lose a life. This is serious.

told the Hyundai dealer 2 years(March 2021) ago that I was concerned about my oil light flashing periodically between scheduled oil changes. No action other than oil changes and one time they added a couple of quarts "no charge" as it again was low. Continued to change oil more often than necessary and the frequency increased. Multiple other car repairs have been happening and the oil now has to be added weekly to maintain proper amounts. Had to change spark plugs 2 times with in 5 months and now another engine light came on today 11/15, and when I check the code at a parts store I was told is was a P03001 and P03002 which was something to do again with the cylinders misfiring. Everyone I have spoke to says this is an engine issue and it is under recall. I did place a claim with Hyundai Care USA after being told by the dealer that it would be better if I did this instead of them. The assistant manager also confirmed that the engine is covered 100%. I did this in September after the second repairs. The Regional Manager finally called me back and indicated he agreed about the problem needing to be resolved and would call me after he spoke to the dealer in a day or two. It has been over a week and no one has called. I keep leaving messages. I now have the same error codes, it is November 15 and the spark plugs were all changed less than 2 months ago for the exact same reason. I have been stranded and at times when I accelerate onto traffic the car will not respond. I do not use the interstate anymore as I cannot predict when the car will slow down and not get enough speed and cause an accident. I only drive to work and back right now. I was given this website by the employee at the parts store along with some information concerning P1326 codes and they are engine related. I will upload the most recent repair receipt.

Please attach recall to my vin as this is exact issue I am having.

My engine failed and was repaired under a campaign recall. Tim Short in Pikeville ky kept my vehicle 3 months to install new engine. Check engine light came on on the way home the day I picked it up. Made appointments to go back and have it checked and they said catalytic converter was clogging up but it would be my responsibility to fox it at my cost. Asked If it would be safe to drive oh yes you may lose a little Power over time but should be fine. Left the dealership and didn't make it home the car started vibrating and sh*t down got it started back and barely made it to a place to pull off. Car had no power, smoke boiling out of engine and exhaust. Dealership and hyundai refused to cover having it towed back. This last engine was the 3rd engine put in this vehicle due to recalls and this one didn't even make it 3 weeks. There is definitely an engine problem with hyuandi.. inhav been left without a vehicle for 3 months and have to have it towed back again at my cost. I wasn't even given a rental while it was being repaired. The car has 121,000 miles but has had 3 failed engines. Something needs to be done.

The engine is consuming excessive oil. My vehicle is available for inspection The problem has been confirmed by an oil service company Valvoline in Munster, Indiana The "oil" lamp appeared on my dashboard for a brief moment. I filed claim with BBB Arbitration for the Hyundai Theta Engine Recall but since my engine hasn't blown up, they will probably deny it.

While I was driving, my check engine light came on. It wasn-??t flashing so I was going to continue driving to a parts house (because the dealerships around me were closed) and have them check the codes that were present. Immediately after I had that thought, I noticed the car was smoking and the battery light and the traction control light had come on, so I proceeded to pull over and shut the vehicle off. I got out and noticed the hood had soot on the edges. I called 911 and watched the car go up I-??m flames. This all happened in less than a mile. I noticed a fluid of some sort had sprayed out of my vehicle onto the road and the underneath the vehicle was coated in the fluid. This is still being investigated but I know of a lot of Hyundai/Kia vehicles have caught on fire while driving. I-??m not 100% sure of the cause yet, but I want to document that this did happen to my vehicle. I would love to update as soon as we figure out what has caused the car to catch fire while I was driving.

The vehicle is used as a commuter car, and driven primarily on NJ Turnpike at high speed. Over a two month period, on four occasions, the engine has shut off. All dash lights came on, and all power assist controls failed. Managed to get to shoulder of road, and after a few minutes, car would restart and run properly. The fourth time it happened, as I coasted onto shoulder, the car restarted by itself. Took car to dealer for diagnosis and repair and was told there were no codes and it "could be" any number of parts not working properly, but no actual diagnosis. Was charged $160 dollars, and I took vehicle home. But when I looked over the invoice, I found the description of problem was not what I had told service rep, so went back to talk to service manager. He told me to bring it back in and he would have it rechecked. Was told they drove car 35 miles a day but it never stalled. However, invoice shows same mileage went brought in and sent out. Again, they said they could find no codes, so they could not diagnose any problem. I went and picked vehicle up, but I drove through the dealer's parking lot to leave, I saw the engine service light was now illuminated, and returned the car to the service department. Was told they would check it out, and I went home. After three weeks, I called to find out status of car. Was informed they had yet to look at it, but would do so shortly. A week later I was told problem was a bad VCM Motor Assembly, and I was charged $788.70 dollars, to replace a part that apparently fine, when I dropped the vehicle off. Read numerous posts online by owners reporting this same engine shutting-off problem, since 2016. But no one has stated a definitive cause, or repair, by dealers. As to whether that was the cause of the engine shutting off, I will have to see.
