4X4RDSTR New battery, new cables, Great connections, and 12.6 volts at starter. Swapped out the starter and no more zip tie sound. The bendix was sticking upon release of ignition key. A starter may be starting to fail, but begin to have issues retracting the gear from the flywheel.

59 jeep Just another thought: Battery voltage, positive and negative ground connections etc. can also affect how the starter engages. Found this out the hard way... cost me 2 starters and a flywheel in my 76 vette. All because the positive battery connection was faulty. Worth a look ! Good luck

4X4RDSTR Finally bit the bullet and decided to fix this problem. I replaced my starter and all is well. No grind or zip tie sound. The issue was the starter can start to fail and still crank fine, but the bendix gear is slow on retracting after the engine starts and you release the ignition key. Leaving a problem like this for very long will cause your flywheel to become burred, chewed up, and worn. It was recommended by an ASE mechanic to try to file any burrs and imperfections off the flywheel teeth, by slowly manually turning the engine by hand when removing the starter to also help prevent binding of the gear retraction. The problem only happened in the morning due to the starter bendix being cold and sticking. After using the starter, the starter id warm and also subject to engine compartment heat. Just make sure you remove the negative cable from the battery and wear eye protection before beginning.

Just curious. I know this is an older thread, but are you still getting the "zip tie" grind when starting? Have you brought it to the dealer. I get it in the morning, no matter how fast I release the ignition key and my AC and fan is always off. It has been happening all summer but only in the morning one. Thanks

Mango-Jeepin Before calling the dealer I figured I would do a search for this issue on the forum.... and I'm glad I did! I've been getting the grinding sound on and off and I just went out and tested it and it does only happen when I leave the A/C on and turn the Jeep off. So... I take it its just a jeep thing and I don't need to call the dealer?

chucky cheese All right the latest. turned off w/ a/c on yesterday, this afternoon started jeep and grind happened with a bonus! When the fan blower came on (there is a couple of seconds delay before it starts) there was a second split second grind. So it has something to do with the fan belt and the load on it when starting. I do not have the grind when the compressor is not engaged at starting so I have narrowed it down to either the a/c compressor is engaging at start, the belt or tensioner is at fault so it could be in the electronics that is not eliminating the compressor at start or faulty belt tensioner. Now I have never had a problem starting a vehicle with the a/c on. I tried my dodge van and it starts then a few seconds later the compressor kicks in. My thinking is the electronics are not eliminating the compressor load at start. From other posts Or the lack of posts about this makes me think it is a problem on certain jeeps. I do not want to make a special trip to the dealer for this so I will wait until I have a real problem before I go. I have not yet had a visual on this. It seems my wife has to put on makeup before she goes outside so I really don't have the time to wait for her to get prettied up to come out to start it. But when the planets line up and the moon is in Uranus (thats why it smells like cheese) and the makeup and outfit is perfect I will get her to sashay out and start it as I have the hood open and observe and being careful to observe from the side so as she cannot cash in on my life insurance! So for now TATA ,God speed and cio!

You should pop the hood before start up and have someone fire it up. Might be able to get the area it's happening in.

I wish I could play too. It's just not cold enough for mine to do it. Next few days I'm getting lows in the 20's...we'll see
That's my plan. It is hard to coordinate someone to help when it only does it once when sitting 24 hours. Also gotta remember to shut it off the day before w/ a/c on.

I will experiment further and post. Oh yeah I am sure somebody will post that the compressor should not kick n when starting but I believe there is a fault with the system not Eliminating the compressor load at start causing the belt to vibrate.

Just my $.02

Oh, and I have yet to use the A/C in my Jeep, if that adds anything.

ghendrix6 Mine did the same thing for a couple months in cold and hot temps. Now it seems to have stopped.
03-21-2011 02:24 PM
Peepers The a/c comes on with any combination with defroster, so if it is an a/c problem it would happen in the cold or warm.

Mine does it on combo also

redz1 Keep us updated. I feel like if I address the issue to the dealer they'll just blame it on my offroad adventures, since first impression of my engine bay is quite filthy. But the issue has been going on since before I took the jeep offroad

Mr-Ford-drives-a-Jeep Mine does it too. I haven't localized to the ac yet but one thing to keep in mind for all of you is that the ac pump does get engaged when you have it to the defrost or floor positions. It does this to pull moisture out of and not cool the air to aid the defrost process. So even though your ac button says off the pump is still engaged. I'm gonna put it on dash only vents to make sure the pump is off.

Mine stared the noise when it was approx. 55f out. My son was using it and he had the a/c on because it got up to 80f or so the day before. So it sat out all night at 55f with the a/c in the on position. Got in it at 4pm temp approx 80f started it and the grind/buzz happened. My son was about 8 feet in front and I asked did you hear that? and he said yes. So the next day same thing happened. I haven't had the a/c on the past few days, had the sunrider open so I have not shut it off and left overnight w/a/c in on position. Gonna start it today and see but I forgot to turn a/c on before stopping last night.

Maybe the drain back valve is allowing the oil to escape, so it takes a second or two for oil to get up there?

chucky cheese OK, started it today without a/c on and no grind. Tomorrow I will start it with the a/c on.

chucky cheese It could be the a/c. Will experiment and post results.

mlebwill I got that this morning for the first time. This morning was the first night outside of the garage and it was in the low 40's when I started the car. I'm going to leave it outside again tonight to see what it is. It sure doesn't sound like a starter motor grinding, in fact I'm not sure it was metal on metal grinding, more like plastic on metal. But I wasn't expecting to hear anything like that so I wasn't paying attention.

It sure got the "What the Hell!!!" juices flowing this morning.

chucky cheese Not the cold. I'm in louisiana and mine does the same. Only on the first start of the day. Did not do it today though. I posted about it hoping someone else had the same issue and what it is.

Basically, if I leave my jeep in the driveway for over 2days without running it, the morning I do start the engine, the second the engine starts there's a quick grinding that goes away in a split second. Only happens once and then its fine until the next morning...the rest of the day it sounds fine.

Is this normal? The noise kinda sounds like a zip tie being tightened (that's the only thing I can think to describe it as).

My jeep is only 3 months old with 3k miles, and its a 2010.

It happens so quickly... Just a split second when the engine starts... But its a sound I haven't heard in any other car I drove, so I got worried...
mine does exact same thing when its really cold out!! i know you said its not cold were you are.
