Manifold/header/muffler/tail Pipe Problems of Jeep Commander

Fuel tank where filler hose connects has started to leak when I fill tank. Also exhaust manifold bolts are made so small and weak that they brake and dealer keeps telling customers that engine noise of knocking is normal on Commander.

Jeep started making a ticking noise randomly one day. I made an appointment with the local dealership and they explained the the exhaust manifold bolts were broken on both sides. Very strange considering that my Jeep have never been off-road. After doing some research it has become very obvious that this is an issue with all of the Chrysler vehicles with the 4. 7l v8. The company doesn't try to help with the cost and actually charges an astronomical amount to repair something that I consider bad engineering on their part. The broken bolts cause an exhaust leak that can now be detected within the car and I think is potentially dangerous for the passengers. With the bolts broken it also allows the exhaust manifold to warp cause addition damage that now needs to be repaired/replaced.

Mid September after dropping kids off at school the Jeep died twice right in a row. The Jeep also started this weird hard down shifting in certain gears. A few days later the Jeep died again after I got on the highway, while I was driving 70 mph. Since then the shifting is getting worse. A check engine light comes on when it dies, the codes were read by an auto parts store. There were multiple codes, electronic position sensor, intake, and manifold. I tried to file a complaint with Chrysler but they will not complete it until I pay their authorized dealerships to read the codes. After resetting computer it has not come back on. The Jeep still shifts erratically, and I discover that the etc warning light does not work. Why???. I don't know we have had this car for 5 years and I have never seen the light. Something is definitely wrong. Please help. Also neither my husband or myself are tall enough for our knee to even think about bumping the ignition switch.

Upon starting the vehicle heard to be what sounded like a loud exhaust leak under the passenger side of the engine. While driving the noise seemed to lessen / go away. Upon doing research many reports that if you hear an "exhaust leak" upon start up then fade away, it could be a possibility that the exhaust manifold bolts have broken. I took it upon myself to look under the hood on the passenger side while the vehicle was cold, and low and behold the bolt that goes through the heat shield and manifold and into the engine block was cracked in two pieces separating the manifold from the block. I call my mechanic, he said bring it down right away, he looked at it and saw that there was 2 bolts broken on the passenger side. Again many complaints from customers online about the same problem, and the only way to fix this issue is to lift the engine out of the vehicle to drill out the broken bolts that are stuck in the block. Now. My mechanic tries everything all sorts of angle tools, other tools and cant remove the bolts, so the only thing left to do is lift the engine. I have the engine lifted and find that there were more bolts broken on the driver side as well. I go to the dealer and buy all new "upgraded bolts" ( as the dealer specified) for this along with gaskets, rear main seal, fan clutch, oil pan gasket etc. I explain to the dealer the problem and they admit to the problem but there's no recall on the 4. 7l only on the hemi for the broken manifold bolts. I ask what was the problem. The dealer replied " the manufacturer installed the wrong grade bolts from the manifold to the block. " now I'm out almost $3500 for parts and labor for a known problem that hasn't been recalled, this is something Chrysler/Jeep should be on top of considering this is an ongoing issue. This is my second Jeep, and I'm not sure I'd purchase another one.

As I have now read online of hundreds of complaints regarding the same problem. . . I was driving down the hwy at 70 mph, the engine just quit on my and everything shutdown. I was able to move the car to the side (without and power steering) and stop completely, take out the key, reinsert it and it started up. No problems after that until I was driving the hwy again in September and it did it again with the same results. I have now taken it to the dealership (wolfchase Jeep in germantown, TN) and they are replacing the map sensor and a couple of other things - including a manifold gasket - for a total of $1000. Interestingly when I asked the service rep. If Jeep has a problem with this, he denied any knowledge of such a problem!.

The engine warning light was been on and off for the last 2 years. We have changed-out O2 sensors and other fixes but the problem persisted. The issue was discovered by the local Jeep dealership: four of the bolts attaching the manifold onto the hemi 5. 7l engine of our Commander were broken. The bolts and exhaust manifold gasket are being replaced - $642 cost.

The car drove fine pulled it in the garage. Got up Thursday morning to go to work the car turned on and started shaking and I turned it of tried once more it would not turn on at all. So then I changed the crank sensor the cam sensor got a new battery put new spark plugs the truck still would not start. Had a garage look at it they said it was the intake manifold so they therefore told me to take it to Jeep because it was covered under warranty. I took it to Jeep and the told me this would not stop my car from running, they have had my car for a week and no diagnosis. This car is only three years old but Jeep customer service says to me you bought it used so you dont know what was done to the car. So I say to her your qualified mechanics you have working at the dealers cant do the job. What great customer service Jeep has. And the dealer is suppose to be getting in contact with Jeep techs in corporate to try and figure out what the problem is. Still no car 6/01/15.

On all 2006 and 2007 Jeep Commander's with 4. 6 4. 7 and hemi engines have an issue with exhaust manifold bolts breaking, requiring extensive repair, which can cost in the thousands. The internet is full of this issue and it is known with all dealers, but Chrysler themselves ignore it. If the issue isn't fixed because of the price the engine can have more issues due to the bolts. Please look into this issue since the company that makes the vehicle wont. Even on there own forum it states "Jeep Commander problem model years affected: 2006, 2007 engines affected: 3. 7l v6, 4. 7l v8, 5. 7l v8 hemi average mileage: 79,474 mi (40,000 mi - 154,000 mi) verified 3. 7 v6 and 4. 7 v8 engines may develop exhaust leaks due to broken exhaust manifold bolts. Exhaust manifold gaskets and bolts should be replaced as necessary.

The contact owns a 2007 Jeep Commander. The contact stated that while driving at various speeds, the vehicle stalled several times without warning. The vehicle was able to restart after a few minutes. The vehicle was taken to the dealer to have a diagnostic performed. The technician was able to duplicate the failure and stated that the manifold air pressure needed to be reset in order to repair the failure. The contact believes the failure was not corrected. The failure mileage was 50,448 and current mileage was 50,872.

The contact owns a 2006 Jeep Commander. The contact stated that the vehicle emitted a loud clicking sound after starting. The vehicle was taken to the dealer, who diagnosed that the studs that held the intake manifold cracked. The dealer stated that the engine needed to be taken apart in order to determine if the manifold needed to be replaced. The manufacturer was made aware of the failure and filed a complaint. The contact was then referred to NHTSA. The vehicle was not repaired. The failure mileage was 85,900 and the current mileage was 86,151.

The problem began initially in 4/2010 when the vehicle had 53,165 miles on it and the engine would idle roughly, the esp/bas indicator would come on, the check engine light would come on, and the traction assist indicator would all come on at the same time. As soon as all the indicators would light the car would handle poorly, not shift properly, and at times simply stall out on the highway while traveling at high speeds. I brought the car to my local Jeep dealership and upon inspection they found that the intake manifold had melted and come apart thus it needed to be replaced at a cost of $485 which was fine considering the car overall had not given me many major problems so I proceeded to have the work done. A couple of weeks ago the same problems began happening again (the engine would idle roughly, the esp/bas indicator would come on, the check engine light would come on, and the traction assist indicator would all come on at the same time) so I brought the car back to the same dealership and upon inspection they found that once again the intake manifold had melted and come apart thus it needed to be replaced at a cost this time of $685, mind you the car now has 96,057 miles. My main concern is that the intake manifold lasted only 42,901 miles and had to be replaced once again. I voiced my concerns to my service advisor and he stated that the first time the upper manifold had gone bad and that this time the lower manifold had gone bad, that may very well be the case but if you look at the invoices the part numbers are exactly the same (53032774aa). I understand that the dealership can only do so much so I am now appealing to you as it seems that the intake manifold for my 2006 Jeep Commander has a factory defect as it literally melts and begins to come apart especially with the extremely hot weather in south florida every 40,000 miles or so.

My 2006 Commander with 40,000 miles has had the following problems since it came off the lot. The vehicle stalls and I obviously lose power and steering but there are no error messages in the computer, the 4wd does not engage - the warning light for that comes on but there's no error message in the computer. The window's roll up and down incorrectly - the gasket on the exhaust manifold has been replaced and the kicker of all problems is when the vehicle goes through a minor puddle of water or the automatic car wash the steering wheel locks completely until the water is gone - try driving that in the rain - Jeep was finally able to duplicate that problem by putting a garden hose under the car and squirting water on the underside of the vehicle - this problem apparently cannot be fixed and they can't believe that no other Jeep owner's aren't throwing fits. So much for the lemon law - the steering problem wasn't taken seriously by the previous Jeep dealers -I went to a different dealer altogether however, it's too late.
