Michael Brown Posted March 30, 2023 Share Posted March 30, 2023 Hello All I have had my 07 hybrid since August last year and it has broken down twice. Each time it could not be fixed on the side of the road and had to be transported home on a recovery vehicle via RAC. first time it broke down was back in November. My local mechanic Colin Campbell recommended a specialist and Alfie was taken to Brightspark Autos in Southbourne nr Emsworth. Peter Holland gave it a check over, replacing 2 hybrid battery cells, checked the electronics gave it a road test and it was good to go. This cost £530. I broke down on side of A34 this last monday. I'd stopped for some lunch and engine would not start. The green READY light started to illuminate, then nothing, engine did crank a bit. Peter who fixed before is busy for a month. Any suggestions please. Quote Link to comment Share on other sites More sharing options...

PaulE Posted March 30, 2023 Share Posted March 30, 2023 Problems can often stem from the 12v battery being bad, have you had this checked and is it the correct battery, which on do you have fitted? Also do you have any error lights on the binnacle such as ABS, VLC and the possibly little red car? 1 Quote Link to comment Share on other sites More sharing options...
Michael Brown Posted March 30, 2023 Author Share Posted March 30, 2023 Thank you Rojie and PaulE. The battery fitted presently is a YUASA YBX 3000 60Ah 500 A(EN) I have been told this is a stop start/battery. I had this fitted after the first breakdown. The battery that was on it when I bought Alfie was a YUASA YBX 3000 60Ah 540 A(EN). Means diddly squat too me. A host of lights came on inc VSC Quote Link to comment Share on other sites More sharing options...
PaulE Posted March 31, 2023 Share Posted March 31, 2023 (edited) I looked up the specs of the battery online and it looks like a standard battery. The one I have is the Yuasa HJ S55 23R which is an AGM battery and according to Mark at Hybrid Repairs is the correct spec not just for start stop but for regenerative systems in the hybrid. The OEM battery is the Panasonic S55 23R. I believe the 12v battery starts the hybrid system then the HV battery starts the engine. It could still be a fault with the HV battery. I found when my HV battery had a fault and wouldn't start if I disconnected the neg terminal on the 12v battery for about 10-20 mins (to allow the HV system to go to sleep) and then re connect the vehicle would start and drive enough to get home but don't use the air con or heater as this drains the HV battery. Try if you can and get an ODB to USB lead (see Amazon) and a copy of Toyota Techstream to load on to a laptop you can check the fault codes. There are plenty of Youtubes on this and some posts on the forum.

Michael Brown Posted March 31, 2023 Author Share Posted March 31, 2023 I'm sure I do not have the right battery, many thanks for your suggestions. The 12 volt battery is mounted to the rear of the front seats, at floor level, so size is important to fit Quote Link to comment Share on other sites More sharing options...
