Report: Exhaust Manifold Bolts May Break
Jeep Commander Problem
Engines Affected: 3.7L V6, 4.7L V8, 5.7L V8 HEMI
Average Mileage: 83,587 mi (40,000 mi - 154,000 mi)
Our Commander developed a weird puttering noise when accelerating if the engine was cold. Gas fumes would be prominent in the cabin during this time. After a few minutes the engine would warm up and the noise and smell disappeared. A little bit of researched suggested an exhaust leak and this problem with the bolts.
The local shop confirmed the problem. Four bolts, two on each of the read banks, needed to be replaced. The cheap thin bolts used by Jeep were to blame. The location of the struts make it a rather difficult job. Part of the exhaust and transmission needed to be dropped to facilitate the repair. Had this failed, the engine would have needed to been dropped.
I requested higher grade bolts be used, hopefully reducing my odds of this happening again. The repair came in around $600.
Spoke with Jeep Customer Assistance Center. They will not assist in the repair due to the sage and mileage for my vehicle and are shrugging it off. The rep said that this repair would be covered under their 3 year/36,000 mile warranty. They said all complaints get put into a database at corporate headquarters which could then be used for a recall. If you haven't already, please contact them at 877-426-5337. Jeep needs to hear directly from the consumers.
Note: If anybody is told by Jeep that they've never heard of this problem, my case number is #22294684. May not be a bad idea for people to post their own in the future.
Self diagnosed, heading to the dealership tomorrow. If this problem is so common, I feel the manufacturer is at fault.

Same issue with bolts breaking to cause the manifold to warp and leak. 3,000 miles ago we had the 'left' side replaced entirely ($425+), however there was no mention of the potential that this would happen anywhere else. Not being a car guy (or doing my own due diligence I suppose...), I was not aware that there were two manifolds that may need replacing. Very disappointing that the dealer did not mention this (wishful thinking, I know), or that we could replace the bolts on the right side relatively inexpensively prior to the manifold itself needing to be replaced. Result: another $425 bucks donated to Jeep/Chrysler/Dodge. Continue to be disappointed by Jeep/Chrysler/Dodge, unlikely they will get any more of my business. My tax dollars already went to bail them out, the least they could do is make up for the piles of shit they made in the mid-2000s.

Noticeable exhaust noise, especially when first cranked and on acceleration. Mechanic said that all 4 bolts are broken, and it will require the removal of the entire engine to replace them.

I've had it repaired twice by dealer under warrenty. After warrenty my independent mechanic told me to "live with it" since it is just going to happen again.

YEP.. The dealership stripped the screw and dropped it into the manifold. It's still in there. They told me that it would cost $1200 for them to drill into the manifold and get it out. Yes, this was a dealership and I told them no thanks.

ticking noise from a broken exhaust manifold bolt. This is the second time it has happened.
