Engine had a critical engine failure, per dashboard?,while driving on highway, no engine warning ⚠️ lights before failure! car engine switched to low gear and immediately only drove about 10mph. I was able to move to slow lane then off to the shoulder...my car was not hit by any other car...but it did come close. Drove perfectly fine up to engine failure/seizure. This is an extremely unsafe condition for a car engine to be in suddenly. Again no oil or engine lights on before engine failure. Hyundai case has been created # 18049339 and dealer notified. Both appears to me not to understand the seriousness of this safety hazard... engine has been replaced by a certified mechanic after Hyundai refused to help with this matter. I will include response and invoice for engine.

Disappearing oil. For years now my car has been progressively using oil. Now I can't even go a week without putting in more oil and it has fouled spark plugs and left me stranded twice now, and continues to excessively consume oil. I finally got tired of this at 130K miles and took it to reliable Hyundai in springfield, mo. This dealership has been completely useless in offering any help, answers, or solutions. They've already charged me $400 for a 'combustion chamber cleaning' - told me I would be reimbursed if it didn't work, then when it was obvious it didn't work they did not refund me. They have made me jump through hoops in hopes I will eventually get a new engine, but repeatedly remind me ultimately that may not happen. In 2 months I have had to go to reliable Hyundai, missing work, 11 times for their oil consumption test when it's obvious nothing is going to change because 'that's Hyundai's protocol. I am going to lose my job for attendance and even after that, Hyundai still might not fix the issue. Horrible company, with horrible practices and customer service. Now I'm stuck with a car that has lost a tremendous amount of value, continues to devour oil, and Hyundai doesn't want to do anything about it until after I go there nearly 15 times. Unacceptable. When I bought my car I didn't get a 'it'll prolly only make it to 140K miles' discount. Force Hyundai to recall all of their faulty engines for oil consumption as well! if I wasn't so diligent my engine would have seized by now. I shouldn't be punished for making sure my vehicle is properly maintained.

My check engine light turned on and my car has power hesitation during acceleration. This happend 1-2 days out of the week until the forth time it happened the check engine light stayed on and continues to have power hesitation as well as high idling at all times, burning oil, smoke coming from the exhaust, and the brakes are extremely hard when needing to brake. I took it to a local mechanic and they did a diagnostic that returned a code of P0010 and they referred me to a Hyundai dealership for repair. I was also given a technical service bulletin with a campaign number of 15-01-022-1. I took it to the dealership and they also came back with the same code. I have paid for the parts and diagnostic and they couldn't give an estimate of when the parts would be available because they are on back order. Here I am two weeks later calling the dealership to follow up and was told by the parts department that they contacted Hyundai directly and there are 1800 of those parts on back order with an estimated time of being at least two months for the parts to come in. Hyundai also stated that they have submitted a high priority for them. I will be without a vehicle for who knows how long.

While driving on the highway, my engine abruptly died with all subsequent warning lights coming on. I had no power, beyond battery power, and was stuck on the side of the highway for 2.5 hours during rush hour. Engine would not restart or turnover representing a likely catastrophic engine failure. My local Hyundai dealer did not seem surprised by this revelation and they still wont tell me what's wrong even though the car has been un their possession for 72 hours.

The connecting-rod bearings in the engine wore out prematurely. My car only has 75,000 miles on it and does not come up on a VIN search at Hyundai as a recall vehicle even though it has the 1.6 gamma motor in it. The description from Hyundai of the issue is the following, "abnormal knocking noises from the engine, reduced power or hesitation, illumination of the "check engine" light or the engine oil-pressure warning light; or a burning smell, oil leaks, or smoke." This is exactly what happened to us when the car died. We took it immediately to our local mechanic who was shocked at how worn the bearing wear and the large amount of metal shavings in the oil.

I was driving on the highway and all of a sudden the engine lost power and my speed dropped to 20 mph. I could not go any faster. Other cars were honking at me and almost hit me as I try to get to the shoulder of the road. The check engine light came on and I had the car towed to Hyundai of duluth ga. They scanned it and said it was code P1326 knock sensor detection. There is a NHTSA service campaign for this- https://static.NHTSA.gov/ODI/tsbs/2019/mc-10154682-9999.pdf (tsb #19-01-006H. The problem is Hyundai dealer does not have a fix because they said corporate diagnostic equipment is not working. They have had my car for 5 days now. They do not have any loaner vehicle while my car is inoperable. My complaint is they should have loan cars or pay for rental cars for customers with this problem. I demand they fix my car soon or give me a rental car to drive to work.

I drove straight to the dealership the noise would occur at when the car was idling or I my vehicle was accelerating. I arrived at the dealership at 8am. At 9 am I was informed that a bearing in motor dropped in my motor and caused metal to fun through my motor and that I would need a new motor.
