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. Update: 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.

I can see that there are two broken bolts that needs to be replaced the exhaust leak is pretty bad. it's a shame that all these people have to pay for their mistakes. I'm looking into a class action lawsuit against Jeep corporate.
Same issue. I do it myself. This video helps a lot. https://www.youtube.com/watch?v=dYn_iPiRexM

Self diagnosed, heading to the dealership tomorrow. If this problem is so common, I feel the manufacturer is at fault.

45000, 80000, now 135000 miles. Always at the back of the engine. Replaced drivers side twice, now the passenger side has broken. Obviously they're too small for application. I had never seen 5/16 diameter until this engine! Typically 3/8 diameter. Well you can't tap the block out bigger, you just have to keep replacing. Honestly this has been a great vehicle for us, my wife loves her commander. That's why we're still driving it at 135000. If they made it again we would buy one. Tows my boat and snowmobiles and has allot of room inside. No idea how they thought the 4 door jeep wrangler could take it's place without a v8 option. Sorry a Durango is not a replacement either. Just my opinion!!

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.

Same thing here. I am not paying the dealer to do it though. I'll do it myself.

Two broken manifold bolts. Warped manifold. Also broken front bushing mount. At dealer now $1169.

Yuppers I've got an exhaust leak too
2006 Jeep Commander - 4.7L V8 77,000 mi,
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.

Manifold bolts replaced

Driver side exhaust manifold bolt is broken, still attached to heat shield. This problem should be recalled.
Theres a ticking sound, an obvious exhaust leak coming from the passanger side of the engine. I took my commander to a mechanic, he told me that the bolts to my exhaust manifold broke. I have not fixed it yet, the issue started not too long ago.

Broken bolts on both exhaust manifolds. This issue was fixed once before by the dealership {$800}... This time I will do it myself. I'm halfway through the repair and it is a pain. The process is long with poor access to the hardware, but is possible to do without removing the engine.

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.

my jeep has the same ticking. I got under neath to see the problem and sure enough broken exhaust manifold bolts.

Bolts broke, not fixed, noisy ticking until hot

I heard a ticking so I brought it into local muffler shop...fixed for $400...he said the exhaust manifolds warped over time so he used a thicker gasket and replaced a couple broken bolts...now 80k miles later, my Jeep is ticking again...I'm assuming more bolts are broken given their smaller size than traditional bolts. Jeep should recall these...and stop using cheap designed parts.

Ticking noise in engine. Would tick when you started the car and then stop after it warmed up. I started researching and found it was 1 of 2 issues. This one or pin valves. This one stinks too because one of your valves get stuck. $6-700 before valve sticks or $$ after. Well, the noise keeps getting worse and I broke down and took it in. Turns out (as my life goes) the bolts broke in exhaust and the seals have to be replaced. $1200!! It can cause you more wear on engine, losing oil- we all know what they will do so it has to be fixed. Bolts break and it does this much. Wow! Already replacing door handles, rear cup holder and hatch hydraulics. They really use some cheap parts for such a nice car. Cheap parts for cost of car too. Not my first jeep so I know they can be good cars but these little things are annoying and cause big repair bills. Id rather pay $1000 more for the car to have quality bolts and plastic. Just saying. I love the car but hope after this I'm done with repairing things due to cheap parts used. Other than this. Great car. Rides great, luxurious. Sleek looking and proud to own it.
