Head replacement 3.6L Pentastar (both sides)

I have had my 2011 WK2 for about 3 months, and while leaving work it shuddered, then died. When I turned the switch back on, the CEL light was then illuminated (after it died). The CEL had never been on before. The dealer pulled the codes, and it was the common #2 cylinder misfire, so they replaced the head under warranty. After they fixed the left side, they said that #3 and #5 are down on the other side, and it will be $2400 to replace the right head, since that side was not covered by warranty.

They explained to me that there was no way that this was a Chrysler failure, so it would not be covered. I'm no mechanic, but I'm pretty sure the other half of the motor, made by the same people, is probably similar to the other side. Also, they said I was probably running on 5 cylinders (with #2 down) for quite some time, and the truck only died because #3 and #5 failed, thus only running on 3 cylinders. Could running on 5 cylinders for continued use cause others to fail?

This same dealer looked at me like I had 3 heads when I was confused that they did not provide loaner vehicles or comped rental cars... I just feel like I'm getting rail-roaded here. Any information or advice is greatly appreciated.

ETA - The Jeep has 106,000 on the clock, so is just outside the normal 5yr/100k powertrain warranty.

Re: Head replacement 3.6L Pentastar (both sides)

I just noticed you said 106,000 miles, so the dealer is correct about no warranty. Chrysler does not automatically provide planets. Some dealers do and sometimes a call to customer service will get you one ... Grudgingly.

Re: Head replacement 3.6L Pentastar (both sides)

The Left side head is the only one under the extended Warrenty. The right side head is fine and running on 5 cylinders won't cause a head failure. At 106k, you probably need new plugs if they have never been changed. You may have one or more bad ignition coils which could cause the problem.

Unless the dealer did a leak down test on all cylinders and can show you the results, I think they are just trying to get some money out of you. Go find a good independent shop and have it looked at.

Re: Head replacement 3.6L Pentastar (both sides)

Hi,

My question is: If they are replacing the left head, should I get the right head done at the same time?

I've got. 2011 with 83,000 miles and it's being looked at for left head replace. Should I do the right side also? There have been no trouble codes on it.

I's love to know soon, I'm going under the knife on Aug 18.
