Won't start

My battery is new, key has new battery as well and I had no warning lights on the dash.

does it crank at all and just not start or does the starter not even turn

It just clicks, happened with no warning

my interior lights come on, dash lights up and still have beeping sounds from leaving key in ignition

Turned out to need a software update that caused "inconsistent starting".

This is to all jeep commander owners and also jeep grand Cherokees made n the same year. My no start issue started a year ago after a flood which I promptly associated the starter issue with. I had everything mechanical replaced the start issue arose. I went in repeatedly which ended up with re-replacement of mechanical parts. Still no fix. So this is what I have done to fix the problem- fuses 39 and 40 of the integrated power module, drivers side forward fuse box, behind the battery has 4 total electrically actuated switches "1/2 A 190" that can be purchased at any auto parts store- REPLACE THEM. I pulled all of mine to be safe a my Commander has run ever since and started immediately each time that I have tried. My original switches were so hot that they burned my fingers. Being inquisitive I broke them apart to reveal a mechanical contact that had burnt points to the point of actual metal blow out and arc marks. In the mean time repeatedly(fast) try to start the vehicle and it should start.. This issue is like a ghost haunting your cars as the vehicle started sometimes with no repeatability or codes. also tap on those switches to reset if the switch is stuck also feel if they are hot after driving, could be a key indicator of a future problem, they should be warm but not hot. Good luck and I hope this helps.

This is an issue that many people are dealing with and one that Jeep is not admitting to. A class action lawsuit is also in process to replace the integrated power module with something more robust. I hope this helps.

Wow! This is occurring to my vehicle right now and jeep is giving us a hard time. How can I get in on the class action suit? This is the second time dealing with this and now our jeep does not start at all. Thanks for this post!

I just got my 06 commander ignition replaced due to a recall. It started from the dealership, but I stopped at the store and the jeep never started back up. Sitting at the dealership with the mechanics scratching their heads...

We have been snowed in for 2 days been cranking up just fine yesterday... but today the temperatures dropped to 5 degrees and the thing just clicks when I try to start up!!! help

Have the same no start problem. Takes three to four time to get it going. Very random. Can never get it to have for my mechanic or dealer.

i have 2010 jeep commander, this is very first time my jeep will not start. I stopped to get a coffee, came out and vehicle was dead. And like everyone here all my lights work, interior and head lights. All dash lights and warning chimes work, but still had no start at all. My jeep is 7 years old, this shouldn't be happening.

Mine was the connections to the starter. It's known on the commander, all lights on dash come on but won't crank. I take a pipe climb under the jeep move the wires going to the starter and it fires right up

WCM problem if your red dot light is blinking when key is on position. The ECM won't see the key "164 transponder" until you replace WCM. It is located near ignition switch ring. Skim reader.

This isn't an answer, but more of a question. I have an 06 jeep commander 5.7L. All the lights come on in dash as well but won't start. It's on its second started. Had it replaced 4 or 5 years ago. What I'm wondering is that this happened a couple months ago after a hard rain, and then "fixed" itself and has been fine until 2 days ago. There was another hard rain again. I just don't want to spend tons of money on fixing things that aren't broken or in needing of repair. Could it be a distributor cap issue or something else? Could it be that I need a 3rd starter? Please help!

Im going through this nightmare still right now. Im Trying to have it fixed next weekend. I spoke to a jeep tech and he said the factory starter is a poor design drwing too much current through the harness, As a result it chews through the harness making a intermittent start issue, It engages the solenoid (Click) but not enough current to turn over the starter until you get lucky. He said the repair is a new starter and Harness. Dealer quoted me 315 just starter installed. Awaiting call back for the additional harness quote.

I cut the yellow wire that plugs into the starter and spliced in a new wire and connector.. it is fixed no more issuse with it not starting any more. It was a pain because i took driver side tire and wheel well trim(or whatever you call it) off and there is limited space. But im also a big guy

I have a 2007 Jeep Commander doing the same thing and they can't find nothing wrong with it a month at the dealership and nothing went to pick it up wouldn't start only on Friday so if you can figure out the problem let me know too

Just went through this a few hours ago. The steering wheel and brakes also felt locked on me. Had to use the other keys to get started. But I had to turn it all the way to start then after the click turn just a little left then back full right to start and started right up. I thought it was a hoax so I tried again with same key just started everything started up just fine. Tried the first set of keys and everything locked up on me again. Went back to my main set of keys turned and turn just clicked. Then I did the full turn wait a sec turn back left a little then back full right and starts right up. Had the ignition changed last year at the dealership.

I figured out the "random start" issue with my 2006 Jeep Commander Limited. Replaced the engine grounding cable that attaches to the firewall, then replaced the exhaust to frame grounding cable. I used a HEAVY grounding cable from the exhaust to the body, and a heat resistant & oil resistant copper cable at the firewall to engine connection. Fixed.

Same issue, had the recall ignition switch done at dealer. ran fine for months, then had to park it for a few months. while parked i had a trickle charger on the battery. started up fine every time. then one day i cam e back and the trickle charger was blown! battery dead, jumped the battery, all the lights and bells come on but no start. I'm going to start with fiddling with the key like Guru3SZcc did, then move onto the fuses like ncorliss said. if that doesn't work, i'm disconnecting the battery then putting key in ignition and holding in start position for 10 seconds then reconnecting battery and hoping for the best. I was told not to mess with the yellow wire to the starter on my own because if it comes off it's a live wire and may spark. Wish me luck... How about that class action suit???

My 2006 commander wont start lights flashed but notjing what do i do Please help

Just had a cold night and went to start my jeep for my daughter's field trip and no go, have replaced the starter a few years ago and usually it's just the yellow wire with a bad connection. Just doesn't about 2 hours cleaning it and trying to get a good connection and still nothing. I have also done the key fob a few years back, going to try the fuses and a new connection for the yellow wire, then almost starter if I need tp tomorrow. Fml, I love this jeep but this is getting soooooo old!

Literally experiencing this over the past week+ pretty regularly. Last Thursday the car wouldn't start at work. I had it towed to my local mechanic. He tried starting it every 30 minutes on Friday and it started right up (car sat over the weekend) and again started it regularly on Monday. I picked it up on Monday and started the vehicle 15 times in the lot before leaving. All week it's been fine but this evening when I was leaving work, it didn't want to start. I was searching around online for this issue, as I just wanted to get home. I opened the hood and moved the harnessed wires around for a few seconds, went back into the car and it started right up. Obviously a short term fix and I may not be so lucky the next time but it's definitely electrical. I had the starter replaced in August 2017 from the dealer. I'm planning on calling my mechanic on Monday and explaining this, and maybe things will make sense. My issue is, I'm not sure which wire, or wires, are bad. 2007 Jeep Commander Base w/ 152,700 miles

And may I add. My Jeep days are done after this Commander. Already have my eyes set on a Nissan Pathfinder but would like to get a few more years. Sadly, another unreliable Jeep has me hoping that my car starts next time I go out. Shame on Jeep for charging the prices they charge to give consumers an inferior product time and time again.

For anyone experiencing your Jeep not starting getting the click when you go to turn it over but nothing other than that. Go to the truck turn off the head lights from Auto or the on position to the off position and turn the stereo off turn the key to the on position and try starting it. Let me know what happens.

GuruL122F I have an 07 commander that doesnt have auto lights so wut is your answer now? For everyonr reading I have had this problem for 2 n a half years n if I take a hammer n wiggle the starter wire (which is towards the passenger side of the brake booster) usually starts.

Yellow wire connector at starter terminal

2008 Jeep Commander 3.7L. Like so many others here, I had all my lights on the dash but nothing when I turned the key. The starter would not even click. Removed the skid plate with a 13mmm to access the starter on the driver side. Pressed and moved the wire harness going into the starter terminal and then started right up. Thank you all for the good advice.

My wife's commander 08 doing same thing, starts the nothing next time !! I'll check the wires going to starter, I wonderd if it was battery in key fob !!

what are the part numbers of the black relays that are being replaced trying to buy new ones. please let me know as my jeep is doing the samething and i have done everything other then replace these relays and its still doing it so this is my final guess of what it could be,

My 06 Commamder would not turn over. Did all of the stuff above and still wouldnt starr. Took to jeep dealer they said it was a something in the ignition between the key and ignition switch. Well it is a custom part specifically made for each vehicle. This was Feb 2019 said it was on backorder. August 2019 part came in placed in my Commander ans it blew righr away. So placed another custom order well guess what still waiting. It's been over a year and Chysler has no answer for my dealer on when part will be in. They also cancelled my order twice and told my dealer sorry we just dont know when. So my Jeep is sitting at the dealer w brand new tires, struts, and shocks for last 16 months with no idea when it will start again. If anyone knows away around the key/ignition issue please help

Have 2007 commander wouldn't start all lights on dash came on and one never seen before #9 security light had dropped the key it separated didn't put back together when I tried to start had no Idea the key would be the problem put the guts back in key guess what it started. The key is very important what's crazy l have always had to insert the key to open the door the buttons on the key have never worked to open door .but must be intact to start the vehicle.

Just bought used 07 commander doing same thing. Started doing this 2 weeks after I got it. Randomly starts , sometimes it starts on its own , a jump always starts it . Took it to be tested mechanics can find nothing wrong . It could go days without doing this then..2 x in a day. What is problem ?? I need this fixed asap
