I have a 2012 Elantra. About two - three weeks ago I noticed my Elantra would emit a light vibration / shake when stopped, but still in drive. About 5 days ago, when I started my car, it sputtered and shook, then stalled. I restarted it and it sputtered and shook and I turned it off. I restarted it and it had a rough idle for about 2-3 seconds, then it smoothed out with what sounded like an occasional misfire. I revved the engine and it seemed to solve the problem, but the engine lite stayed on.
I drove it to the Hyundai dealership and when I picked it up the next day, they said the computer showed a misfire and they could not replicate the problem, so they reset the computer. *That was what they printed on the work order.
What they told me verbally was that they believed it was a large piece of carbon that broke free and got sucked in to the cylinder to the degree that it effected the spark plug, enough to cause a misfire. I responded by stating that their belief did not make sense to me. That's when the service rep got a smug attitude with me and repeated his statement.
I told them I did not believe that to be the case. The service rep insisted that was the likely culprit. I'm a pretty nice guy, but I have zero patience for BS. This is when my @$$hole switch got flipped to the "ON" position.
I reminded him the car was not even a year old, I purchased it with 6 miles on the odometer, I changed the oil with Mobile 1 synthetic & replaced the oil filter with an OEM filter and installed a crush washer, I treated it with a fuel system cleaner as recommended in the manual, as much as I don't like E10 fuel, the alcohol in E10 fuel that I purchase from a reputable brand cleans enough that with only 8000 miles on it (most of which is hwy miles), there is no way enough carbon could have built up to be the problem in the manner in which he described. Further more, if you firmly believe what you are telling me, then document it by adding it to my work order (as I shoved my work order receipt toward him).
His response: "Ummm... well... (silence/speechless)" He offered to keep the car and take a closer look at it. I told him that I did not believe he would after the line of BS he just gave me and that I would return if the problem repeated it self and that would force the issue.
Any thoughts on the light shaking I'm feeling when my car is stopped, but in drive? I do not race the car and I'm light on the pedal. I did take it for a test drive and for the first time I stomped on the gas. When I pulled in to the garage & stopped, the light shake was still present while it was still in drive.
