I have a 2010 RRS S/C purchased in January. It's an incredible vehicle, but has been unreliable for me. It's currently at the dealership for the 2nd time in as many months undergong diagnosis and transmission review for what appears to be bizarre electrical problems. The first time this happened, every warning light on the dash came on followed by multiple error messages. I lost power steering and virtually all engine power. The vehicle was towed to the dealership on a flatbed, and a few days later I got it back with a "no fault found" diagnosis. The problem did not rear its head while at the dealership so the fault codes stored in the ECU were reviewed then cleared.

A week ago last Monday a similar problem occurred (all dash lights and multiple error messages), but this time the transmission wouldn't shift out of low gear. The dealer has had it now for over a week and they are "still working on it". The ECU's session files have been forwarded to LRNA but since this is the first time this problem has been seen, there is no knowledge of the cause nor is there a fix. The FSE-Field Service Engineer has recommended the vehicle's wiring be checked and to have the transmission pan pulled, and although they did find a high-resistance ground point and fixed it today, I have very low confidence that this is the root of the problem.

Although the RRS is a fantastic vehicle when it works, my confidence in it has eroded, and I'm really not sure I'd buy another one. Fortunately for the rest of you, this does not seem to be a common problem. I am currently reviewing the Lemon Laws for my state.

I saw a Santorini Black 2010 RRS S/C on the road today and drooled... until I remembered that I actually own one.

"Love" my Pegasus but to be honest if I'd spent oddles of cash on a NEW mega bucks Mk3 with issues I'd have no problem in chucking it back at the dealer

I also get a message every time I start the vehicle (when I use it daily, it starts) that says something like "Check spare tire - low air pressure". ???

... And you did check the pressure of your spare tire, yes? :wink: If it's a full size spare (they were mounting compact spares up to MY2009, no pressure sensors can be installed in compact donuts), that wheel is monitored by the TPMS module just like your running wheels and will display a fault if the pressure is too low, except that the fault message extinguishes shortly after you start the car so as not to annoy you for the entire trip if you really do have a flat tire temporarily stored in the spare wheel well.

Yes - the dealer investigated and said all checks out and I should not get the
message and they have no answer as to why ......I just want my car to work right :!:

Barmats,
Your problem is caused by the high speed can bus going down for some reason. That reason could be a loose or bad ground, poor connection or any module (ECU) on the high speed can bus circuit. With some time they should be able to narrow down which system (module) and then check all circuits pertaining to that module for integrity. I can sympathize with your situation, but give them some time as there are no magic wands to correct this type of fault. Good luck and enjoy your new RR. ibis1 :wink:

Well, after almost two weeks and 325 miles of dealer test-driving I finally got my car back. The problem was indeed in the can bus, and it turned out to be a faulty wire bundle running under the front passenger seat. The wiring insulation had worn off due to chafing and was shorting. This also explained why the problems only occurred with a passenger sitting in the right-front seat. Fortunately, LR was able to correctly diagnose this and repair the problem. Although the Jag XF was a nice loaner, I really missed my Rover and it's great to get it back. The LR's service department has earned my respect in the way they treated me and handled this repair. Hopefully, this is the end of my problems.

Hello there,
I have a RRS 2010, that I also had delivered in January, I have had problems since my second day of ownership. I have the SAME ISSUES, and numerous other electronic issues related to my nav screen, ventilation system, seats, etc. This car is mechanically fine, but an electrical nightmare. I have taken the car in over 10 times for different issues--and I just do not have the time to deal with this anymore. I feel like the car has some sort of virus, or short somewhere as I haven't seen this anywhere on the net. I'm glad that I'm not the only guy out there. I am also exploring my rights within my state as I no longer have faith in the car.
