I've had my 2016 Summit for 3 1/2 years and covered roughly 77k miles in it (currently on 96k). Only had a couple of issues during this time...

1) Centre bearing on the prop-shaft failed. Not a replaceable part (!) so entire prop-shaft replaced under warranty at 37k miles.

2) Adaptive cruise control failed at 89k miles due to water ingress in the radar sensor. Annoyingly without the sensor operational the regular cruise control stops working too so it had to be replaced ... out of warranty! This was the biggest bill to date at £2,766.

Despite the single huge bill - and the twice yearly servicing costs (every 12,500 miles) - I wouldn't part with it, supremely comfortable over stupidly long journeys (previously had a 9-5 Aero with those amazing seats!), looks reasonably smart in granite crystal metallic (has flecks of purple, silver and gold in the sun), starts on the button every time, heated wheel is a godsend in winter, and ventilated seats a godsend in summer, and it copes with any terrain I can point it at.

£2,766 for a sensor ? Ouch eek

Must be cutting edge tech and 10 hours labour to fit it ! laugh

£2,145 for the sensor, the rest was diagnosis and labour! Forgot to mention it also required 3 weeks at the dealer as they were "Waiting for a sensor calibration tool from Jeep UK". Still great car, but totally lousy dealer experience.

Nice to come across this thread, and hear overall good reports. I'm looking at a Grand Cherokee to replace my old Audi a6 Avant sometime when this lockdown eases. I've got a lot of camping gear and a dog to be lugging about this summer.

I've always thought this car is pretty handsome, and really seems like it is a good value to buy used. There seems a wide (-ish, this is not that common a car) selection to choose from nearly a 10 year run, with a lot of extras for the money (compared to German/JLR equivalents). I see that in Overland or Summit form as you get air suspension, sunroof, lots of electronics and the what the kids really get excited about - rear heated reclining seats!

Does anyone know if it's worth remapping the engine? According to the websites, the 247bhp and 550NM standard engine can squeeze out an extra 40bhp and 90 NM torque with a remap, plus "improved MPG"? Of course the diesel it's never going to be Audi 3.0 BiTdi quick and have nimble handling, but would be good to get an extra bit of poke.

I’ve had fast cars and the power is more than adequate in standard form in my view. Good engine and gearbox.

I echo this. You don't need more power, it's not the sort of car that needs it and the torque is way more than adequate.
You mention the air suspension, its a must IMHO, the models on normal springs are bloody awful.

If you want more power then get an SRT jester

It had crossed my mind! Though I accept the people above's points that this is a 2.5 tonne SUV, there's enough low down power to get off the line but speed is not its primary purpose.

So let's see what's around in a couple of months when I start looking in earnest.

To update the thread after my last post, I'm now a proud owner of a 17 plate Summit. Collected at the weekend!

[url]|https://thumbsnap.com/iZHdfhAm[/url)]

I was particularly attracted to this one because of the all black exterior, and the all terrain General AT3 tyres that make it look quite purposeful. After 50k miles it is in very good condition, the indie dealers, Crystal MoTors in Northampton did a good job in prepping it, repairing any dings and fixing any issues. There's nothing really of note to tell is is a 4yr, 50k car.

I bought the Jeep to replace an ageing Audi A6 avant, as I wanted something to take more camping gear and more room for a new dog, and something that can handle long journeys to France, Alps etc. The kids went for the reclining, heated rear seats, which I've seen in few other cars.

It comes with a lot of equipment as standard. Safety aids covering emergency braking, blind spot warning, adaptive cruise, rear camera, sat nav, stop start, lots of electric gadgets, big 19 speaker stereo, panoramic sun roof. The 17 version also has the new/traditional style gear shifter and acoustic laminated glass, and active noise cancellation. Leather seats (with cool ventilation in front) and a suede-like black headliner make it a very comfortable and roomy place to be.

With the standard extras It also does seem like you get a lot for your money.

Driving: well its certainly not a German saloon. It is not very happy going round bends and over bumps in the road, the air suspension gives a bit of bounce to everything and the engine gets quite raucous pulling away in 1st & second if you want to get a move on. But its very well behaved at cruise on motorways so looking forward to some long journeys. Surprisingly too, it has a decent turning circle, I was able to uturn around a mini roundabout in one go in the style of a London Taxi which I wasn't expecting.

Its actual footprint is slightly smaller than the A6 avant so apart from height, it doesn't feel too big to drive about in. Parking is pretty easy especially with sensors at both ends as there are some big blind spots to see around.

Off road, well I had a bit of a drive about some local unpaved roads and found a few gentle slopes and obstacles to try out low range which were easy meat. I can't see it ever being challenged by what it may be thrown at it during light off road use, muddy fields, flooded roads and snow are going to be what it encounters rather than trekking across deserts. I did note that at maximum height setting, the suspension tops out and clunks very easily over bumps. "They all do that sir" is the consensus online, so not too worried about that. The tyres don't seem to make any excessive noise.

The fuel tank takes 93 litres of diesel so my first fill up was well over £100, gulp... I'll be interested to see how much MPG I can get from this 3 tonne brick. Range currently says 350 miles after about 90 miles driving, which is i gather pretty typical for a single tank, so not disastrous, hopefully improves on a long straight run.

One thing that is a bit of disappointment is the boot space. Its listed at 780litres, compared to the A6 avant (565l) but it "seems" less, maybe an optical illusion. The spare wheel intrudes so the boot platform is about 10-12cm higher than you would think, so even if packing gear up to the ceiling, I really wonder if I get the same in as the A6. We shall see. The retractable load cover is also a complete joke, that's gone straight in the shed as it is positioned far too low, and has a big gap to allow reclining seats to make it of any use. Tinted rear windows protect from prying eyes anyway. When the seats fold down there is a massive space for cargo carrying though.

On the flipside, rear passenger space is broad and deep with lots of legroom so the kids and dog will enjoy it, and we may well be able to stash gear under seats and ifootwells on full trips without being too intrusive, unlike the Audi which was full to the brim.

I'm considering getting a towbar for bikes/storage and/or small trailer, A new one needs fitting, there may be some limitations due to the Adblue tank being in the way so need to investigate that.

However, all in all very pleased, got a nice smart big new car with lots of modern additions. The kids love it, Mrs P looks suspiciously at it, and I'm looking forward to our trips to the West Country and Wales this summer, and further afield later on.

I don't know where you've heard the stories - if it is the same as the 2015+ GC, it is great - I have done about 120,000 miles so far in two cars and it has never skipped a beat.

I am changing from the GC shortly, to a new Defender, however that is just because we need a change and we may well come to regret that!

I know of one that was very poorly & needed replacing. But my Jeep tech when he was working for a main dealers said that was the only one he did know of.

A lot of internet reading (mainly USA forums where its in lots of Dodge pickups also) lead me to this conclusion also.

Thing is, Its actually a good engine I've read, for what it was designed for, working hard and running for long journey's. it was designed for commercial use.
Short journeys have caused engine failures from what "appears" to be contaminated oil blocking up the oil passageways. The EGR valve being the blame ( diesel experts can offer more detailed advice)
There seems to be a thing in the states of getting the DPF's and the EGR's removed. There not so hot on checking up on these things it seems …..
My usage would be mainly short and medium trips, with a few long trips occasionally. So it wouldn't have suited me unfortunately, because apart from that it seems a bloody decent vehicle.

Having had a quick look, it appears the old VM engines were problematic, but the 3.0CRD in the latest GC is post Fiat joining the group and is regarded as a good and strong engine.

YMMV

Mine was the 3.0 CRD and it didn't put a foot wrong in 2.5 years and 20k miles. Good mix of short and long journeys.

Lovely car!
Thanks! I believe it was an all black STR that caught my eye a few years ago and made me take a look at the Grand Cherokee. So I was on the look out for one (I think you can get a special edition "Night Eagle" in similar blacked out spec, but doesn't have the same level of features and functions, like the air suspension as a Summit or Overland). I must have just got lucky and found a used diesel Summit with the chrome deleted as an option. I like the yellow brake calipers too, nice touch, though it really is not a performance enhancement!

Regarding the 3.0 diesel engine issues, I also worried a bit when I saw it was VM Motori who made the engine as it reminded me that they put a VM diesel engine in an old version of the Range Rover that got some pretty bad press back in the day.

So that feeling made me do a bit of research online, top of the list in Google is the somewhat scary report: https://www.motorreviewer.com/engine.php?engine_id... but further searching around, there don't seem to be many (any?!) reports of major issues with the engine or gearbox, general view is if you carry out an engine oil service at least every 10,000 miles, it will provide many miles of trouble free driving.

This is one of the reasons for buying a Jeep. I'd love a big Range Rover of some variant, but reading and hearing about the issues they face, I just couldn't live with a used one even with a manufacturers warranty. There don't seem to be many gremlins reported with a Jeep. I guess in the UK they are rarer, so few cars to go wrong, but like the posts above, most people generally have good experiences. Even the dealership I bought this Jeep from, who says they also sell a fair few Range Rover Sports & Discoveries, said almost a matter of course they replace the plastic inlet manifold as soon as they get one in, and they much prefer selling the Jeeps as they have very few warranty problems (yes, noted, that was the sales person talking....!).

I remember when I used to catch the train into London and me and my fellow commuter mates would talk about their cars and one friend who had a Range Rover would regularly complain about things like the gearbox selector breaking, then a few other randoms in the carriage would pipe up they had the same issue with theirs too, and how they fixed it - it felt like a kind of Land Rover self help group some times!

Yes there's a number of things from that to silly stuff like the magnetic crank sensor ring falling apart and the gearbox needing removal to change it. Have they sorted all these daft things out now?

Just joined the WK2 club, 2015 Overland with just 36k on the clock, was looking for slightly newer but this one appeared with the right mileage / colour / price. Think we are into our 18th year of Grand ownership with various WG's and the previous WK.
