Yes! My husband and I have been wanting to purchase a Commander for a while but weren't sure if it was the car for us. Over spring break we decided to rent one. While cruising down the Florida highway my husband bumped his knee on the ignition key which completely turned off the car. We were very scared and pulled off the road (which was VERY HARD TO DO!)then restarted it. The very next day it happend again. Now we are seriously rethinking if this is the car for us. That is a huge design flaw not to mention a very serious accident waitng to happen.

Different factory, same problem: we have a Commander CRD LTD, manufactured in Graz, Austria, odometer reading at 7k miles (11k km). Engine stalled twice and all power-assists turned off as well. I could swear I did not touch the ignition key.

Sad to see that this seems to be a Commander problem ("National Highway Traffic Safety Administration has opened a preliminary investigation that could lead to the recall or 136,444 Jeep Commanders because the engine stalls unexpectedly", Consumer Affairs, 1 May 2007). But glad that at least the mechanics have to take us seriously now.

As to other issues: loss of tire pressure during driving - we got it. Engine problems apart from stalling - we got it too: Various engine monitor lights go on and off, engine goes on "emergency mode" (as our mechanic put it), i.e. enginge is throttled down until it feels like 20 instead of 218 hp.
Remote control controller stopped working and needed to be replaced, including new keys etc.

Whoever is the first one who gets those problems fixed - pls. post. Will do the same.

We thought the same thing... hitting the ignition key with our knee. Well after many times not hitting it (after the scare I was extra careful not to do so) the engine just turned off... going 80 or 40 mph... it didn't matter. Well the ignition was changed out.. seemed like that has worked so far(it hasn't happened again).
The whistling, we have been unable to figure it out yet. I am going to pick it up today from the shop... I will ask about it.

I had the whistling problem but it was after the windshield was replaced. I found a forum somewhere that stated it was because of a bad seal in the windshield. I had it replaced and have not had a problem since. I have also read that the roof rack cross bars could cause this depending on the position of them. Moving them did not help me.
