Grand Cherokee Limited Overlander 5.7L V8

  • Automatic transmission
  • 120,000 miles


I bought my Jeep Grand Cherokee hemi 5.7 on my birthday for $6,000. It's my first vehicle and it's turned into my worst nightmare. I bought it used and know nothing about purchasing a vehicle, so I just assumed I was getting a reliable car. It was kept in great condition. No accidents, no overdue oil changes, the truck was beautiful.

Two weeks in the engine light appears and a noise like something stuck in the tire starts. I think- oh great. So the day I was going to take it in to have it looked at, the biggest problem happens. My exhaust is vomiting smoke out like it's a damn fog machine. I can't drive it. I tow it to a shop. They said after a compression check that cylinder number 3 has failed and that they could clearly see a hole in the piston. Solution... Replace the engine. WTF I MEAN REALLY WTF.

I just spent all my money on this vehicle to have it need a 3,000 dollar defect and now I'm screwed. It's been sitting at my friend's ever since. I don't know what to do. I'm so upset. My first vehicle ever that was supposed to be a life changer for me and it takes a sh*t 2 weeks after I buy it. I'm devastated. They say it's a defect in the engines build and I think Chrysler should do something about this for those of us who have had to encounter this issue. It's a beautiful truck but this defect is terrible and not a one person complaint. There's multiples.

Grand Cherokee Limited 5.7L

  • Automatic transmission
  • 62,000 miles

The vehicle was purchase in March of 2007 from Branhaven Jeep Chrysler Dodge Ram (348 W Main St, Branford, CT 06405 (203) 488-6351), 38,500 plus tax and finance charges comes to 42k and was meticulously kept.

But, from the start this vehicle has been plagued with problems that eventually has lead to recalls. The one thing I thought I could always rely on would be engine. It's a Hemi. It has 16 spark plugs and it usually runs smoothly, until the day I hear it misfiring. I pulled a spark plug and found oil in the well. WTF?! Had it compression tested. -A whole in piston #3? This vehicle never overheated. Never had a check engine light come on. The year prior was the 60k maintenance. How is this possible when the engine still starts and idles and I have yet to see a check engine light? The cause of the misfire was a lean fuel/air mixture, on a vehicle that has been meticulously maintained and rarely driven.

Grand Cherokee Limited 5.7L V8 Hemi

  • Automatic transmission
  • 96,313 miles

So I purchased a 2006 Jeep Grand Cherokee 5.7L V8 Hemi four years ago. I have been keeping up with maintenance and constantly checking fluids and taking it to mechanics every time something sounds a little odd. Some might say that I over think everything and too cautious but this brings me to today. I drove my Jeep back from work, home which is approx 26 km drive, went to store to buy some groceries and returned home. Grocery store is about 1 km away from my house. As I got back home and took groceries into the house, I realized I had forgot something so I got back in the Jeep and drove back. As I got back into the Jeep to now go home, Engine revved high and than shut off. I called a Tow and they tried to give me a boost but nothing, battery was still working as radio would still turn on with key in ignition.

I have brought it to three mechanics and all have advised that the engine has ceased, which is ridiculous as I have taken care of this vehicle like a child. Two mechanics I brought it to have advised that Hemi should not cease as they are a piece of art with the design. Well, great piece of art this engine is and with only a 155,000 Km's on the engine, it's infuriating.

Engine was having a problem with cylinder number 3 as it got filled with fluid (believe it was gas or oil). About a year ago, my computer was acting strange and advising that my car was overheating. So I took it to three mechanics as well, including the Chrysler dealership and all said nothing was wrong, just a bad signal from the computer. Now I'm stuck with a vehicle that engine does not work and I've tried calling the head office of Chrysler and all they can tell me is that I would have to take it to a Chrysler dealership before they can comment on it more. I've now read multiple reports online from owners of the vehicle that have complained about their 5.7L Hemi ceasing on them too. I've always promoted the quality in Chrysler and have owed multiple Chrysler in the past. With what is happening to me now, not sure I can trust Chrysler again. Sad thing is, I was planning on buying the wife a new car this year and had planned to go Chrysler but this has changed my mind.

For anyone else having issues with their 5.7L V8 Hemi engine, we need to hear your voice so others do not get into the same disaster as the rest of us are facing. Chrysler should really be doing something and stand behind what they build and charge a hefty price for their technology.

Extremely disappointed and once again, infuriated with Chrysler.

Grand Cherokee 65th Laredo 3.7L

  • Automatic transmission
  • 91,000 miles


I bought my Jeep 21 months ago. I have had so many thing go wrong with this Jeep. It was a leased before I got it and I think it was in a wreck. I was not told but not sure. Anyway I told the dealer about it stalling out 2 times when turning and they said it was OK. This last week it stalled out backing down a ramp and had a rear end wreck. I had loss of steering and brakes. I called Jeep and they sent an inspector to look at it. Friday it started this thing at 2500 rpm. It bogs down like loss of power but it will run it you let it shift slow. The engine light came on and won't go off. So it didn't get to the dealer. Jeep told me not to contact my insurance till they inspect it to see what's going on with it. Jeep better get it right before someone gets killed with this problem. It could have been me if it was on the way to work on the highway. Come on Jeep what are you waiting for?

Grand Cherokee Limited 5.7L Hemi

  • Automatic transmission
  • 44,000 miles

One morning I jumped into my 2006 Grand Cherokee and made a couple stops within a 5 mile radius. When I got back into my jeep to go home, my vehicle started up with a heavy miss like a spark plug was totally fouled and not making a spark. I towed jeep to dealer-they checked it out and told me #7 cylinder had no compression and that the head was cracked!

I was very shocked because my jeep has never overheated nor have I ever had to add coolant to the system!

Dealer checked it out further and told me that the block will need to be replaced also! The mechanics carried me into the garage and showed me 4 other jeep Cherokees with similar issues. They (the mechanics) themselves feel that something is wrong with the 5.7 engines because they were seeing too much of the same issue.

Needless to say I am going to get my jeep fixed and sell it and never by anything from Chrysler again. I don't think there have been enough complaints of this issue for it to be looked at by the dealer but something needs to be done so more people don't run into similar problems. Dealer needs to cover that.

Grand Cherokee 4x4 V8

  • Automatic transmission
  • 63,000 miles

I am a 55yr. old woman who gets regular oil changes and only drives approx 10,000miles a year My 2006 Grand Cherokee V8 only has 63,000 miles on it.. I am the first and only owner. On Thurs. May 31st, I heard a slight ticking that went away when the engine warmed up. By Friday it was a loud knocking. I called the dealership and had it towed. When they called they said they had "bad news" that the engine was BAD!! I am out of warranty and the price to replace with a remanufactured engine is approx. $7,000. I stillowe $2,000. I have a complaint into Chrysler they are willing to cover $3,500. So I am expected to pay $3,500 for THEIR defective engine that seized. Do not own a Jeep Grand Cherokee WITHOUT an EXTENDED WARRANTY. Chrysler is NOT standing behind their Product. I dont care if its under warranty or not..it only has 63K miles and cost $32,000!!!

Grand Cherokee Limited 4.7L V8

  • Automatic transmission
  • 57,000 miles

2006 Grandcherokee limited but purchased from the dealer mid 2007 with 50 miles. They renewed the B2B warranty at that time but I did not realize that did not include power train. I do not drive the vehicle hard at all, check gauges and engine light came on, engine over heated and I towed it to the dealer. The diagnosis is the engine should be replaced at $8,600. I spend $400 just disgnosing the problem.

Chrystler Jeep said they could possibly give $1000 toward the fix only if I paid $1000 for a engine breakdown AND if they did not like the results I would be stuck with the entire bill. After three Jeeps, including 2 Grand Cherokees and more in my family I will no longer be a Jeep owner or ever recomend a company that will not stand behind their customers. Buyer Beware.
