Help with 2007 Jeep Grand Cherokee Car Intermittently Not Starting/Alarm

Hi,

I have been looking at this forum because I am having trouble with my Jeep not starting, and I'm far from home so I'm in a bit of a jam. If anyone can help, I'd greatly appreciate it. A few days ago, my Jeep Grand Cherokee Laredo (2007) would not start when I turned the key (all I would hear was a click and the engine wouldn't turn). 30-40 minutes later, it would start. This happened twice, and then we took it to a mechanic, who said that nothing was wrong with it and that he was able to start it 15 times in a row. We continued to drive for 2 days without incident. Today, it once again would not start for awhile, and also, the factory alarm on the car, which had never been on previously, was suddenly on and started going off when I tried to turn the engine on. Also, whenever I unlock or lock the car, there is now a beeping noise that wasn't there before and the car beeps several times when I lock the car using the key fob and the doors are closed.

1) Does anyone know if the alarm/car not starting are related, and what I should do (replaced key battery already based on advice on this forum)?

2) Additionally, is there a way I can permanently disable the factory alarm?

Thank you in advance for any help.

First question, how old is your battery? If the original I would start there as the WK is very sensitive to voltage levels. Don't bother testing if it's original, just replace it. It's either due or will soon let you down.

Assuming your battery is good, next culprit of the no-start issue is corrosion on the yellow wire at the starter solenoid. This cause a weak signal to the solenoid, which cause the soleniod not to activate the starter. Corrosion is very hard to see since the corrosion issue for many has been where the wire is crimped to the female blade terminal, which is covered and hard to see. Best to replace the terminal. I will send you a pm with directions for this. In the meantime when you get this no start issue you could crawl under the Jeep and tug on the yellow wire, which will often help make a connetion and start the Jeep.

I agree, if you have original battery, its your battery!
Change it you will need one soon anyway, (if its original).

I own a 2008 Jeep Grand Cherokee Laredo - purchased in November of 2007.... it had the exact issues. The battery is factory-original and I followed JKM's advice regarding the yellow wire at the starter solenoid. I have not had a single problem (knock-knock) since fixing it on July 17th
