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.

I attempted to start my car and when I did it every light on the dash was lit up and the gear shift was stuck in park. It happened about two weeks prior and I was able to turn the car off and on a few times and it worked but this time it didn't so I had to have it towed to the dealership. When the tow truck driver came he used some sort of toll he had to unlock the gear shift which allowed it to be driveable. Of course when the dealership looked at it they were unable to duplicate the issue but they found that the ignition coil needed to be replaced and did so.

In November 2018, I turned on my car, and the entire vehicle shook violently. I turned it back off, then on. It shook again, and the check engine line was on. I called the dealership, and they said since the light wasn't flashing, I could drive it over. Turned it on, no issues, drove over. They read the code and replaced the ignition coil. Mileage was 12,884. This morning (May 2), the car tried to turn on, but couldn't (like a dying battery). Oil, engine, and battery lights all came on. Waited a few minutes, tried again, same issue. The third time, it finally started, but shook violently for a couple seconds. No lights illuminated. Called the dealer, they said to drive it over. They are unable to replicate the problem, and said it can't possibly be the ignition coil, and can't do anything for me. The car currently has just over 15,000 miles. All maintenance has been done by the dealership per the schedule. I used the car the evening of May 1 with no issues, as well as for a 45 minute drive on April 29, so, I don't believe it's the battery, either. This is a known issue with this make/model of car. I am afraid it will break down somewhere other than my driveway and leave me stranded or in danger, such as at an intersection.
