2010 Range Rover Sport drive train and electrical problems

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.
