I bought my 2017 Jeep Compass Trailhawk in October 2018 so I have only had it for about 3 months. I live in Utah and about month after I got the car I had an issue with the remote start after it had sat over the weekend for a few days. The weather at that time was still pretty mild nothing too extreme. So I thought it may have had something to do with the fact that I had not driven it for a couple of days. But I still thought that was weird. My husband has a 2010 Jeep Wrangler and he said the only time he has had issues is if the gas tank is almost empty and another time when one of the doors was not shut all of the way. I had plenty of gas and since then I make sure that all of my doors are shut tight when I get home at night. But since that first time. I have had this happen off and on about dozen times total over the last 2 months and there is no rhyme or reason to it. It is fine for a few days and then some mornings it just doesn't remote start. The horn honks only once instead of the 2 quick chirps when it does work. Then nothing. I will try and lock and unlock the doors I get closer to the back door and it just wont start. I was thinking that it might be because the temperature has dropped a lot in the last few weeks. But yesterday morning it was 17 degrees and it remote started just fine and I had about a 1/4 tank of gas. Then after work yesterday, I stopped to fill up the tank. Then this morning it was about 18 degrees it had been about 14 hours and I took the FOB close to the back door and it only honked once and did not start. So anyway, after reading all of the above messages it appears that this is a really random problem. There doesn't seem to be a pattern of any kind. The closest guess that I think may be a possibility is the battery being low. But it is a guess. I will be contact the dealership soon. I will let you all know what they say.
