Engine would randomly idle mild to very rough when started and would sometimes correct and sometimes not correct while driving. This would turn on the check engine light for a misfire on cylinder 4. All ignition coils were replaced, and same code would happen. Hyundai was aware of this being a widespread issue and did a software update (Tech Bulletin 90C042R1). The problem continued, but seemed the check engine light would not come on as soon as before the software upgrade. Took back to dealership and they said the ignition coils would need to be Hyundai brand, change cylinder 4 to OEM and still having the issue. Engine also burns about 1 quart of oil every 7000 miles and often has a rough idle, with very rough idle periodically. I feel this would put myself and others on the road in danger if the engine were to fail while driving due to the ongoing damage rough idling appears to be causing to the engine.

While driving the vehicle this past January, I experienced a brief -??clunking-?? noise in the engine, and the car stalled. The check engine came on briefly and then disappeared. The code identified was a -??faulty crankshaft-?? code. I made an appointment with the dealership to take it in to be inspected, but later that day my son was driving to pick me up from work and the vehicle literally died in the middle of an intersection. No warning, all lights came on in the vehicle, the electrical system terminated, and the vehicle died. I had to have it towed to the nearest garage, which was a Pep Boys, and they diagnosed the problem as an alternator and battery, serpentine also. So. 1300 dollars worth of work later-??. Turns out the car has an engine issue.

While driving my car it just stops. I have been complaining to the local dealership for 1 year and they keep turning me away. My battery was replaced and that is it. I was told I was exaggerating that this was not happening. Yesterday was different from the other times it stopped. My car stopped on a busy highway and I almost ran off the side of the rode a cliff because the wheel and brakes locked up. No one is taking this serious. As I am driving the car will just shut off. The local dealership advised me to drive even further to get it fixed. How is this safe? I was told by rich its my car I own it its not their problem.

My 2018 elentra value edition started knocking in August of 2018. I called the dealership in chillicothe oh and they told me it was fine to drive and to bring it in the following Monday. They said I should plan to wait while they looked at it and that I would be driving it home that day.. I drove about 20 miles and the engine made a loud noise and died. They never told me what caused the failure but there was oil and chunks of aluminum all over the road. They replaced the engine under the warranty. The car had 33,000 miles at that time. Then on December 23 of 2020 my engine started making the same exact noise. The car is now out of warranty with 144,000 miles on it. I removed the oil pan to find the problem. It was the number 3 cylinder. The connecting rod bearing was bad. I cleaned the journal on the crankshaft and measured it with plastigauge. It was 0.001" over the tolerance. I installed new bearing on all four rods in hopes that 0.001" out of tolerance wouldn't be to much. Every bearing on the rod side was worn out and the coating gone. The bearings on the bottom "cap" side were in decent shape except for the number 3 cylinder which was destroyed. After the engine had started and I had drove for around 5 miles it started knocking again. The journal on the crankshaft is to worn for the bearing to work. I have an engine ordered and I am replacing it myself. I have several years of schooling in auto mechanics and have grown up in a garage, I understand the importance of maintenance and never missed any on my car. It had every oil change with synthetic oil, oil filter changed every time, fluid levels were checked on a regular basis as was the air filter. The car isn't driven hard, there is no reason for the issues I've had other then defective parts or design of the engine in this car.
