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.

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.

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

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.

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!!

Mine is the 2005 Grand Cherokee, essentially the same as a commaner drivetrain. The check engine light came on. An engine scan showed "insufficient catalytic converter". There is no sensors for the converter except the o2 sensors up and down stream. The dealer acted like they never heard of this and changed an o2 sensor. The light returned 5 days later. Just got ripped for $200. Seems when a bolt breaks in the exhaust manifold, mine is drver's side, this allows exhaust to vent and air to be sucked info the manifold changing the sensor readings thus the code. Yes it has gotten worst and the tappet noise is louder until it warms up and obviously much worst in the cold. Be real Chrysler bought junk bolts as they have in the past and the consumer is screwed. I have bought three jeeps since 1996 and will never buy another as they have become another GM unethical company, take your money and run.
