Bought a Jeep Cherokee Chief from them, old thing for carting stuff around - part of the pre-pick up agreement was that the AC would be working (it was not working when I tried it in the shop) - they told me that it was fully working when I picked it up and it wasn't until I was some way down the road that it became apparent that this wasn't the case. Next day went to my local AC recharging service who told me that the drier had a hole in it and they could not charge it - Jeep RHD Driers are super rare and eventually I managed to find one in Australia. Once fitted, including new seals, the recharge was successful (happy days) until the heater wouldn't work - it turns out that there are blending doors in the system to mix hot and cold air to the correct temperature and humidity, which commonly fail. Again I resourced a repair kit, fitted it and everything worked fine - just as it should have done at pick up. Being an engineer, and to minimise cost, I did all the work myself - I asked NWA to reimburse me only for the parts used, as I considered that they could have got their mechanics to do the work should I have completed the 100m round trip once they had sourced the parts (which I am pretty sure they wouldn't have managed - it is only that I am retired I was able to spend the time to do so). They have done everything in their power not to pay up - they keep asking for an invoice - which I provided, along with proof of purchase - I think this is simply a tactic to frustrate so that you will eventually give up!!. Given that I spent around six hours doing the work and around twenty searching for parts and investigating the faults I am a little miffed by their approach to say the least. Their PDI and "Service" is a joke - they didn't pick up the AC fault, nor did they notice that the serpentine belt needed urgent replacement, along with a couple of hoses. They don't even take the wheels off to look at the brakes/suspension (their service Manager told me it would be looked at during MOT!!) just oil and filters and that's it. The Alarm/security system has a fault (indicated by the light on the dash being constantly on) but, surprise surprise, this is not covered under the warranty!! Whether or not all the above is common place is for others to judge - all I can say is that my experience with this company has been extremely poor, frustrating, costly and I council anyone entering their premises to tread carefully and possibly have a trusted mechanic with them - once you are out of the showroom/warehouse it seems to me that you are very much on your own.
