If you are purchasing a factory extended warranty. You will not be able to purchase an unlimited miles warranty. They limit the diesel to a 5 years.

The jeep still has regular power train and emission warranty. Same as any other new jeep


I decided not to purchase an extended warranty myself. I don't believe in them. To date my eco diesel has only need software updates and oil changes.

LOL, this is a public forum and Airforums. Mostly just uninformed opinions here. If you want facts you will have to seek them out yourself.

It comes from people wanting to cast doubt about the EcoDiesel. Why anyone that doesn't actually own an EcoDiesel would do that, makes me wonder. Maybe they feel the need to share what they thought was helpful information, but I don't think it helps anyone to spread internet forum rumors.
The only warranty reduction I know of is Ford's Powertrain warranty to 60,000 miles. I looked on Ford's website, but had a difficult time locating the warranty information. I did find basic warranty information here.

I test pulled my 2012 25' FB with a 2014 Grand Cherokee over the Eisenhower tunnel both directions in the winter with the outside ambient around 35 degrees. It pushed the temp gauge right to the red line. I rolled down the windows turned the heat on full blast and finally had to come to a near crawl for fear of burning up the demo before I got it back to Denver. The dealers response after nearly a week was bad fuel end of discussion. I would never attempt the pull if it were summer temps.

I bought a 2014 ML350 Bluetec and now pull a 2015 30' Bunk.The Benz will get warm (max 90C under 200F) on 6% plus grades in the summer. I still turn the interior heat on to assist which will bring it back down to 80C. We have over 30k on the ML with half of that actual towing in and out of CO.

Best mileage around 16 towing cruise at 65 no wind. It goes down to 12 worst case depending on speed and head winds.

I do have the hitch reinforced (CanAm) and pull with a PP.

We absolutely love the ML for towing and daily driving. I am very disappointed that the ML is no longer being offered with the 3.0 diesel so I guess we will need to move up to the GL in a year or two. Maybe low mileage used at that point.

Did any warning lights or chimes alert you to an overheating condition, or did you just feel it was too hot? Does the Jeep GC have a digital temperature readout or just the hapless gauge? If it does have the digital temperature in the EVIC, what was the indicated temperature?
In heavy load conditions, the PCM will limit fuel flow to avoid overheating. If you didn't have any warning chimes or messages, you were within normal operating temperatures.

This was windows down, AC off, heat full on and starting to slow down.

I do not consider this normal with 32 degree ambient and would not ever wait for warning chimes or messages before I started taking actions to keep it from getting there. That is why I watch the gauges.

Others have shared the same concerns. I am a big fan of the Cherokee and have owned several over the years. It was my first choice until the test pull.

[Lance M]

2012FB,
So, you really don't know what the actual temperature was then?

Your test tow is a good read and I thank you for sharing. Your thread caused me to have concern about overheating in the EcoDiesel, but I have not had the same experience that you have, nor do I know of anyone else that has with the JGC or the RAM 1500. There may have been a problem with that particular unit.

I would expect the eco diesel ram truck to do fine. I traded my 2500 HD Denali for the ML to get out of a truck TV.

2012FB: Did you upgrade the cooling radiator fan on your ML-350BT? This is a fairly expensive option ($1,200) but since I made the change, the 'Beast' has never wavered higher then the middle and I've also noticed slightly better MPG (18-20 @ 63 miles per hour). Obviously our AS are different in size/weight, but you should review with your dealer to ensure that you actually do have the HD cooling fan installed (it goes from 65 to 95 watts and uses up all the available space).

I towed my 25 though New Mexico, Arizona in June with 100+ degree days and the AC on. These are not the 14,000 footers but, there was still some long grades. My GC got hot like the prior photo shows. I got concerned, I let off the speed a little, it came down a little, after the peek on the decent it went back to normal. I checked the other temps, oil and trans. They were warmer that normal but within limits.

LongShot, what year is your ML? I have the factory Tow package but will check to make sure I have the HD fan. I feel the cooling is currently good except on the 6% plus high altitude grades and even then with the AC off and heater on it stays at normal. With that said if there is an upgraded fan I will get it put on.

I have just returned from my Easter trip to Fort Lauderdale via Nashville and Saint George Island towing a 30' Signature with a 2014 Jeep GC Diesel. Zero issues. 5500 k. The Jeep is clearly a generational improvement in comfort, handling, and performance (440 lbs ft vs 377) over my previous 2008 Jeep diesel, which I found to be an excellent all around vehicle. I now cruise at 70 instead of the previous 62 mph and obtain the same average towing fuel economy of 14-15 mpg. 44lbs rear and 42 front, 78 in the Airstream. I did use the paddle shifters in the hills, never needed to go below 6th. Oil temps never increased more than 5% but it was cool in them thar hills. Jim

Always good to get such information. One question; isn't the 30' trailer heavier than the Jeep GC and shouldn't that be an issue regarding the safety of towing? I reflect here the laws we faced in Europe where the TV had to outweigh the TT by 15%. Different rules here but many folk say you don't want the TV pushed around by the TT especially down steep hills.

[LongShot]

2012FB: I have a 2012 ML 350 BlueTec; the only upgrades the dealer recommended when I had the brake controller installed (the towing package didn't have that or a 7-pin) was the beefy fan. He did say I probably would never need it as these things are ridiculously overbuilt, but also mentioned that the car would like the extra cooling through mountains so I swallowed the kool-aid and spent the $1,200. My shooting season takes me from Florida to Texas to the Carolinas, Kentucky, Indiana and even into Michigan - With all these miles, I just didn't want to chance anything.

The European rules are as arbitrary as the north american ones (banning safety equipment that is standard here for legacy reasons) and such. The trailers are completely different(narrower standard?) with the axle moved for light tongue weights even on giant tow weights. I don't recall the 15% being one of the rules there, and if it is somewhere it's arbitrary based on using such a lightweight towing setup that it's probably meaningless.

maybe if their "caravans" get into trouble they just detach and lets them fall into a nearby mountain pass. There's a "Hitch Hints" article on this same subject with actual information.

I have 52,500+ miles on our 2014 JGC Summit Ecodiesel, with over 14,000 miles towing our 23FB (CAT confirmed loaded weight of 5,600 lbs, and 560 lbs TW using an Equalizer hitch). Love the paddle shifters and Diesel engine braking across many mountain passes. I watch both engine and transmission temps closely. Though they both occasionally rise, I have never overheated. Though my typical T ranges well below these levels here are my highest observed T's: engine oil - 242 F / Transmission - 195 F. These were digital readings from the EVIC. The idiot lights have never illuminated for either trams or engine, though the coolant Temp gauge has risen to near top of the analogue scale when driving over the CA I5 Grapevine at 70 mph in ambient temperatures of 75 F.
Highway mileage is typically 29-32 mpg at 65-70 mph w/o trailer and 16.4 mpg with trailer at 60-65 mph.
I hardly know the AS is behind me and easily pass slower vehicles over mountain passes.
I did have MOPAR skid plates installed and also the aftermarket plate offered by Dom in CA. The latter is a must-have no matter where you drive as the DEF injector is otherwise vulnerable.
Overall, the JGC is the most comfortable and versatile vehicle I have owned. And I have had many, including European and American makes.

A 30 ' Airstream could also be heavier than a Ram 3500 so I am not sure what weight has to do with the ability of a vehicle to safely tow an Airstream. Jim

If I read WestieHouse post above correctly, the axles of his 23FB are carrying 5,600 pounds of their 6,000 pound rating and the tongue weight computed of 560 pounds put the trailer in an exceed the GVW status by 160 pounds. Exceeding the GVW gets some folks a wedgie in the mind.

We crossed the CAT scales with 5,620 pounds on the trailer axles of our 23D with the tongue yet to be determined on a stand alone basis on level ground.

I might suggest storing the unit with only a few gallons of fresh water in the tank to reduce the load on the axles a little while the unit is in storage.

A friend that restores Airstreams suggested the axles service life may not be as long with a nearly capacity load on them all the time.

Our Classic axles are supporting about 8,200 pounds or 82% of their 10,000 pound capacity.

The bigger issue is tongue weight. The JGC Ecodiesel is rated at 720 lbs max tongue weight. All newer AS above 23 feet (and including the 23D) exceed this amount. That was a determining factor for our selection of the 23 FB.

The Euro rules relating to the relative weights of tow vehicle and trailer relate to the use of surge brakes, whereby the braking action of the tow vehicle activates the trailer brakes. That doesn't come into play with electrically activated brakes.

Some like a heavier tow vehicle as they believe it is safer. Thousands of semi trailer drivers with trailers greatly outweighing their tractors would disagree.

Interesting comment on being pushed down hills. All those promoting diesel pick up trucks with exhaust brakes are planning on being pushed down hills, when they reference not needing to use their trailer brakes.
