2008 Grand Cherokee began experiencing intermittent starting problems. Without warning the vehicle would not turn over. All dash lights were working. As well as radio, AC, power windows and all other electrical systems. No codes showed on the computer.

Well, I thought the problem was resolved but not so. Three weeks later the problem still exists, an intermittent problem that is proving hard to demonstrate and harder to fix. The GC will at unexpected times not crank. Is it the computer, starter motor or wiring?

If anybody has resolved the problem (you're probably not here) HELP!!!

Grand Cherokee 3L

  • Automatic transmission
  • 130,371 miles

I bought my biggest problem to date, my 2008 Jeep Grand Cherokee Diesel, September 17, 2013. This vehicle has caused me nothing but problems, thousands of dollars and has been a major headache since I bought it. On Nov 14, 2016 I had it in for service and that evening I was rear ended on the highway. My airbag did not deploy but my airbag light came on. It was at that time that I started having intermittent start problems.

The first few weeks after the accident were really bad and took at least 10 turns of the key to get it to turn over. When I turned the key all the indicator lights would come on, there would be a click but the engine would not turn over. One day I went out to start it and it was chilly out and my diesel does not like the cold, but it turned over and then for about three weeks it was fine.

I was troubleshooting to see how to get the airbag light to go off and someone said to try and move the power seats back and forth to make sure somethings was not wedged underneath there. After I moved the seats my intermittent start problems started again. I still owe 7gs on this lemon but I swear I will not pay another cent to repair it. My mechanic said it would probably take 3 or 4 hours of labour to track the problem if he can find the problem. My advice is stay clear of the the Jeep Grand Cherokee.

My auto insurance adjuster said they will only pay for the Jeeps repair if I can prove it was a direct result of the accident. In the first 6 months of purchasing the Jeep I had the alternator replaced and when it conked out yet another alternator put in. Which was ok since it was still under warranty. Right now I won't even go into the swirl valve problems cause it's just too depressing. Everyday when I get the Jeep to start I think it might be the last.

This is not the first time that this Grand Cherokee has refused to start. The battery is fine and the solenoid clicks when key is turned but the starter motor doesn't crank. The Auto Club came to the rescue and towed the Jeep to my mechanic who said it needs a new starter motor. It was late Friday and he was ready to go fishing so I let it wait until Monday and I rang and suggested that there was a comment on "Car Complaints" that indicated lots of similar situations with the Jeep and asked him to look at the wiring connection to the starter motor. He said he had ordered a new starter motor.

He called later and said the Jeep was fixed and ready to collect. On arrival he explained that there was a drop of voltage at the starter motor when the ignition was activated he traced the problem to the wiring harness connection to the Battery!! Two new cables and everything is OK. Apparently the cables were corroded and in poor condition.

Thanks to the Gentleman who added the problem he suffered with the wiring to the starter motor being corroded and loose. I DOUBT MY PROBLEM WOULD HAVE BEEN RESOLVED SO CHEAPLY WITHOUT HIS COMMENTS BEING PASSED TO MY MECHANIC.! Bravo.

Since Jeep knew about this issue for quite some time, now there is no excuse for the parts to not be available. I have hear of so many people that have had their starters replaced and brought their Jeeps into a JEEP MECHANIC only to come out with tons of work done and they STILL have the same issue.

I am waiting at least one month for my turn if not longer because YOU people were irresponsible as far as getting your parts manufactured. If I had a car payment with you there would be no excuse for me not to make the payment would there???? Well there is NO excuse that I have no transportation as this has happened 3 times now and I cannot afford to be stranded and be towed again.

I am waiting for the part, and selling my Jeep and will not recommend nor buy another one.

About 2 years ago my 2008 Grand Cherokee began experiencing intermittent starting problems. Everything would be fine. Then without warning the vehicle would not turn over. All dash lights were working. As well as radio, AC, power windows and all other electrical systems. Had vehicle towed to mechanic. They reported vehicle started with no problems. No codes showed on the computer and they could not get it to fail again. Replaced starter, thinking it was possibly going bad.

Drove vehicle for few months with no problem, before it failed to start again. Again had it towed with same results. A few more months passed with no problems. Then I began noticing a "stutter" or delay between the engine turning over and releasing the key. Was checking out of a hotel, so moved vehicle to load luggage. When tried to start vehicle, it again would not turn over. After about 30 minutes of periodic attempts to start, it finally turned over. Again all electrical systems worked fine when attempting to start vehicle. Drove to mechanic and left vehicle. Started a couple of times before failing again.

Next morning started with no problem for mechanic. He moved to front of his building, turned off and could not get it restarted. After pushing vehicle out from in front of door and several more attempts, it started. Nothing showed on computer again. Replaced starter again (for free) just in case had gotten a faulty one. Drove for several more months before it acted up again. This time took it to a dealer. Failed on them after starting 3 times. They found loose wires to the starter. After tightening the wires everything worked fine...until last week.

I put a new battery in the vehicle within the past year. If I let the vehicle sit for a while it after not starting it usually will turn over. I have read about this same problem. Had anyone had any luck finding a solution?

Grand Cherokee Laredo 3.7L V6

My daughter had the car at college when she experienced problems getting the car to start. Sometimes it started with no problem other times she got nothing. We took the car to a trusted garage, he stated we had an ignition problem and it would be cheaper if we took it to Jeep Dealer. He took to a local Jeep dealer near my daughters college and found out their was a recall P57 but Chrysler had not obtained the parts to correct the problem and 4 months later they do not know when they will have the parts. The first notice of recall was 11/17/14. WHAT A CRIME, MY CAR WON'T EVEN START.

Grand Cherokee Laredo 4.7L V8

  • Automatic transmission
  • 91,000 miles

On April 17th, around noon, I tried to fire up the Jeep after walking out of Home Depot. No lights, power, etc... only a message that read "damaged key". Within a few tries, however, I was able to start it. Fast forward to 3:00 pm. I tried to start it and received the same error message. This time, it took about 30 seconds to get it to accept my key. I was able to get it to the dealer, before they closed.

First, they tell me it'll be fixed within an hour, or so. Then they said they'll call back on the following Thursday. On Thursday, I wait for a call. Finally ended up calling them around 2:30. It seemed like they hadn't tried to order the part yet, because they had to hang up and call me back. When they returned my call, they said it was now going to take 3 weeks to get a part, and it would cost $816 (the WIN module and two key fobs).

At that point, I called the general manager of the dealership, and he was kind enough to set me up with a complimentary car.

3 weeks go by, and I get a call from them. Apparently, several cars have been added to a recall list for the same part. ... Another couple weeks go by and I get a call about the official recall taking part "sometime in the third quarter of this year"!!! He then told me I could have them replace the faulty WIN with an OEM part, but it would cost me $1200 (not sure how the cost went UP by $400.)

After another week or so, he called to say that the Chrysler Rep had signed off on getting the OEM part installed for free, with the understanding that I would return to have the recall fulfilled, when it went into effect. In total, they had my Jeep in their service lot for six days shy of two months!

Everything was great, until last week, when I turned the key and it didn't start. All dash lights and indicators were on, but just no turnover. I continued to try for about a minute, and it finally started. No problems for about 4 days.

Yesterday, in the middle of an all-day downpour, it decided not to start... despite several minutes of trying. My In-laws had to come take my family home, while I waited for a tow-truck. I had them tow it to my house, this time, where I can poke around with it, myself. Of course, this morning, it started just fine. I'm reading through several forums, with several people who have all had different attempts at solving this problem, with everything from swapping relays and fuses, replacing corroded wires, replacing starters, etc.. etc..

At this point, I'm not sure what to do, except to wait for this recall. Hopefully it solves the problem(s). So far, I've dodged a bullet, financially. It sounds like others have not been so lucky.

I'll check back in.

Grand Cherokee Laredo 3.7L

  • Automatic transmission
  • 91,000 miles

This problem started 1 year ago. Was unable to get the starter to crank over the engine. All other accessories on the dash panel light up. Radio works, headlights work etc. This occurrence lasted approx. 24 hours... the tow truck was called , i tried the FOB key one more time and the car started.

Was told by Jeep dealership that the car must not be starting so that they can diagnose the problem. As such have not been able to get the Jeep to the Dealer or an auto shop, as it has started just before it could be towed.

This is the 4th time over the last year that this has occurred. Have rented cars twice in order to have a vehicle that will start and get me to work. I feel like this cat is cursed, as this problem occurs intermittently. My wife is stressed out hoping that the car will start whenever she uses it.

I was told by Chrysler Fiat that the FIX ; replacement ignition module and FOB keys will be available at Jeep Dealerships in late June. I do not have much faith in Chrysler taking care of this problem . I hope that i do not have to deal with another occurrence.

Grand Cherokee Overland V6

  • Automatic transmission
  • 69,000 miles


Throughout the years, I was driving to work and also for a pleasure in my favor car – JEEP.

Like the slogan says: I live. I ride. I am Jeep. I bought a Jeep.

In the last 20 years I bought 3 Jeeps, 3 Grand Cherokees.

The first one, in 1995, Grand Cherokee. One day, in 2001, while on the family trip to Seattle, some thousand miles away from my house, we experienced intermittent shut down of complete electrical supply. Towing the car to the repair shop we were hoping for the best. For a week, we extended our vacation in order to fix our car in two different repair shops. They were not able to help me. We left the car there, unrepairable, and flew back home.

The second one, in 2005, Grand Cherokee. One day, in January 2009, while driving to work, my car suddenly stopped. Not able to start. I had Jeep towed do the service. First they replaced starter and solenoid. Then they find I have a problems with transmission. Then car won’t start numerous times then started like nothing is the matter. Then the vehicle stalled, it became impossible to steer the vehicle, the breaks did not respond, the headlights went out and the dashboard was dark. That time I called Chrysler main customer service, I was only told, we are sorry, the age of the Jeep and past warranty. I donated that car to charity.

The third one, in the beginning of 2009, I bought Hemi, Grand Cherokee Overland SUV 4D. I was enjoying driving that car until a week ago. Planning to go to work, my car did not start. Called AAA service, checked the battery, sure it was good, it was 2 months old battery. Towed the car to the nearest Jeep dealer. After I paid for electrical check, they told me that the problem is WIN module and repair is going to be $1,300. Called the other Jeep service department and they said it will cost about$ 1,600. When I called the third Jeep service center, they told me that they have to check it and it should not be a very expensive repair. I towed the car from one Jeep service department to the other service department. Now they told me that will cost about $800 but they have to order the part and the parts are now on back order. To rectify not to mention the towing and rental cost.

My ignition system failed and my Jeep wouldn't start, I had it towed to the dealer. They said they would have it fixed in 7-10 days, that was a lie. I had a rental for 10 days, its cost me $472 out of pocket. Its been there now for 39 days, it falls under a recall and NO ONE will do anything about it. I have a case number with Chrysler and nothing is still getting done,they will not comp me a rental, all I can do is wait. Every time I call I get a run around from these people at Chrysler Customer Service, this is unreal customer service!!!!!!!!!!!!!!!!

Grand Cherokee Limited 5.7L Hemi

  • Automatic transmission
  • 105,000 miles

Since late October, early November I haven't been able to start my 2008 Jeep Cherokee Limited on a constant regular basis. Now currently can't get it to start at all. Sometimes it starts but most the time not at all after numerous times of trying. I have not been able to drive my Jeep that I pay $634 a month between insurance and loan payment,  because I never know if it does start will it start after I shut it off or will I be stranded. If it even starts at all to begin with!! This has been going on for MONTHS. I literally can't drive it at all. I did get a recall for the ignition switch, which has not been fixed because EVERY dealership I have called says they don't have the parts and there is nothing they can do for me. Not even give me a loaner vehicle to drive while my Jeep sits in THEIR lot waiting to be fixed. But I don't believe it's just the igniting switch I believe the problem starts with the TIPM (Totally Integrated Power Module)

Grand Cherokee LX 3.7L V6

  • Automatic transmission

We would go somewhere and the car wouldn't start, couldn't shift gears, no radio, nothing. Then wait and would eventually start. We had this problem for the past year, thought it was the remote/key, then the battery, finally a friend said check the starter. Followed the wires and the one was corroded and partially unplugged. Finally got it cleaned and plugged in, the clip retainer was gone. This last 2 weeks it started again. Got stuck at a parking lot in pouring rain and lightning. I had a long screw driver to reach up into it, tapped back together, started right up. Took it to repairman he replaced the harness because of the second plug for the starter was arcing and melting also. So far works fine.

Grand Cherokee LX 3,2

  • Automatic transmission

My Jeep just wouldn't start and I finally got it going enought to get it to my mechanic. After a day or two of diagnosing the problem and talking with Chrysler, they figured out that it was the Ignition Module. My mechanic tried to get the part from the internet, other dealers, other suppliers and from Jeep itself. Nobody had one and they are back ordered for 6 weeks! Can you go six weeks without a vehicle? You will see hundreds of people complaining online about the lack of parts from Chrysler these days - very scary.

This will be last Chrysler product I ever own. R.I.P.

So Jeep tells me it is a computer module that has gone bad and oh BTW the part is on National Back Order.

Won't have the module until November sometime.....

Understanding that these things happen all I was looking for was a loaner vehicle - Because its a month so far dealership and corporate have done nothing to help.

Either they are switching to a new supplier or this problem is worse than they are saying it is.

I was lucky it happened in my driveway but this could have happened anywhere as there was no warning. They said it isn't a safety issue - I don't know their definition but if this happened on a highway where the car just dies - def a safety issue in my book....

Sad to say I purchased 6 chrysler vehicles over the last 10 years- I won't be purchasing any more....
