An overnight attempt to charge failed, and then nothing worked. No electiicity evident anywhere - no dashboard display, couild not start the car, cold not even unlock the boot. Called Renault Assist and the RAC attended flr them. The RAC technician reported a huge number of fault codes on his computer readout and a totally flat auxiliary battery. He had no ide how to fix tthe problem, and had to call for a flat-bed loader to take the car to a Renault dealership. It was difficult to get the car on the flatbed loader, because the rear wheels were locked without electric power to unlock them. He had to jack up thte rear and use a winch to load the car. The Renault dealership have since notified me that this is "a known problem, and they have a software fix for it", and are now succdessfully charging the auxiliary battery, prior to re-testing the car.
Does anyone have experiece of this problem?
Twice within a year I have had complete electrical failure, but so far Renault have not traced the fault! Last week I sat in the freezing cold car for two days waiting on the RAC to respond. As I was 20 miles from home. The car is still with a dealership after 7 days. I am seriously considering getting rid of the vehicle as my wife is afraid to tfavel anywhere incase we are stuck on a motorway.
@Alan Colvin How did you get on in the end? My guess was that 12V battery had completely discharged and the car needed a software update.
Before I had my Renault I had a Nissan Leaf that I had a similar experience with. The boot lid was not shut properly, not noticed, the boot light drained the auxiliary battery consequently the car was 'dead' next morning. Fortunately the ev forum new of this problem so charging the 12v battery restored the car. Think all ev vehicle owners should be made aware of this? Maybe the software fix will prevent this happening.
