2014 Grand Cherokee smoke on startup
So, my wife and I bought a brand new Jeep Grand Cherokee in the beginning of 2014, fully loaded, 4x4 with the 5.7l Hemi. Car has been working out pretty good, except for one issue that we've noticed pretty soon after buying it. I noticed that every once in a while, when it starts up, there's a thick white/blue smoke that comes out the tail pipe. My wife comes back from work around 3PM and leaves the car in the driveway, and when I get back, around 5-6PM, I put it in the garage. When I start the car (2-3h after shutdown, car is most likely still warm), it usually gets the white smoke. Bear in mind this is Houston in the middle of the summer, so it is quite unlikely for this to be steam, and on top of everything, it doesn't dissipate quickly like steam would and it also smells.
I have some videos of it but apparently I can't link them here yet.
So I've taken the car in for service a total of 4 times already, and the outcome was:
1. First service call, problem non reproducible, they gave me the car back right away.
2. Second service call: since the problem was pretty easy to reproduce, I just took a video of it and sent it to the service guys when I dropped the car off. They gave me the car back a few days later saying they've looked into it and it is steam coming out of the exhaust, because the newer models don't have a drain hole in the exhaust. I got the car back but I wasn't satisfied with the answer, and I asked to discuss it with the service manager.
3. Third service call, enter the service manager. He looked at the video and agreed that it looks like oil smoke. He also asked a few more question, then decided that they should put break-in oil into the car, which I agreed to. The car was ready a few days later, and they said they no longer could reproduce the issue. I took the car back, and sure enough, a few days later, the smoke is back!
4. Fourth service call: dropped the car off again. A day later, the service manager asked if the car is parked on an incline when it gets the smoke, which it is. Next morning, they say that they've left the car parked on an incline overnight, and in the morning when it started up they were able to reproduce the problem and it's steam, normal operation of the engine. At this point, they started getting pretty dismissive, and they said basically I should get another opinion from somewhere else if I wasn't satisfied with their answer to but they won't spend any more time on this issue.
I've also asked them to show me the same behavior on another car, which they should be able to easily do if that's normal behavior which they've fumbled and refused to do by giving some BS excuses.
While reading on various Jeep forums, I found out that some other people had the issue, and some people suggest it is due to the PCV system, but I also found that there was a TSB for this exact issue:
tsb_wk2_0900213.pdf (apparently I cannot link to it)
Now, the TSB describes EXACTLY to the letter the issue that I am seeing. However, it seems like it only affects vehicles built before October last year, and mine was built in January this year.
At this point, I am pissed. For two reasons. First, I don't care if "they all do it", I don't think smoke on startup is normal operation, and I don't think it's acceptable for a brand new vehicle. Am I wrong here? Second reason, they've misdiagnosed the issue for sure, and they've been dismissive *******s.
I also submitted a lemon law case in Texas against Chrysler, but the first hearing didn't go that well, they said I failed to prove that there's something wrong with the car.
In any case, I am very frustrated. Good job Chrysler, you managed to get a loyal customer - 2009 Ram, 2009 Viper, 2014 Grand Cherokee, that was trying hard to get on a list to buy a TrackHawk when they come out - to never buy a Chrysler again!
