12v battery maintenance, issues, etc.

[Terry10]

So I had a starting problem back in May out of the blue. Would not go into ready mode then it started to flash up a message saying turn the steering wheel each way whilst pressing the start button!! None of that made any difference whatsoever. Neighbour of mine had a jump start pack and it started. Not been a problem since.over the last 3 weeks I have done about 1200 miles and then last Friday I tried to start the car and exactly the same problem as back in May. I now have my own Nocco GB40 and that had no effect at all. Tried the neighbors jump pack and nothing. Called the AA out and the guy checked the Battery and said there was nothing wrong with it reading wise. He was totally baffled and ended up towing me to the dealers. They informed me that they couldn't look at it until 11 November but would try and fit it in if they had any cancellations. Lo and behold I had a call last Wednesday to say it was fixed and I could collect the car. The Toyota dealer has said that it was the 12 volt Battery and it had a fault in it that was playing hell with the electrics. New one fitted under warranty even though the car is 4 years old in a few weeks time. Can't knock the dealer at all for that service. Had a quick look at the new Battery and it is a sealed unit unlike the original which you could top up if required. No manufacturer name or technical details on the battery whatsoever apart from a scan bar.All that gives is safety details ect. Just wandering if it may be an upgraded battery possibly. Shall still carry my Nocco GB40 in the glove box just in case.

UPDATE. IT PACKED UP AGAIN.

Same issue again after 120 miles.Had it towed out to the dealers again and now officially they can't look at it till 5 November. Now starting to loose faith in the car unless they can come up with something positive this time.
