I purchased my Vauxhall Zafira B in 2014 (59 plate, registered in 2010). I purchased it from a dealer in Luton. A few weeks in to driving it, I was doing about 15 MPH on my local road and the entire car switched itself off mid-drive! Total loss of power, electrics, everything. Being an automatic, I had to bring the car to a halt, put it in to park and turn the key again in the ignition. Thought nothing of it and carried on. A few months later, the same thing happened again. Once again, travelling at low speed, like 20 MPH and shut off. The third time and fourth time it happened, was when I was coming towards a junction and slowly braking as you do. The car just switched off completely.
I took it back to the dealer who said it was an issue with the accelerator pedal. They resolved it and I was on my way. A few months later, same issue. Took it back and they said it was a CIM issue. So, they replaced the CIM and reprogrammed both my keys. A few months later, the very same issue occurred again. I took it back and they said its the CIM again. I couldnt understand why it had gone faulty again, but alas, changed the CIM again, keys recoded and back I went. Lo and behold, it has happened several times again since. Thankfully, it only seems to occur at low speeds, but I definitely dont want to take the risk of it happening if Im on the motorway!
Not fancying yet another long drive to Luton, I asked a local mechanic to have a look at the fault codes and this is what he found:
P1614-50: Wrong Transponder Key
P1616-00 CIM (Steering Column Module) Wrong Environment Identifier
B3055-00: Transponder Key Problem
U2105-00 CAN-Bus No Communication with ECM (Engine Control Module)
As soon as he saw the codes, he said you have a faulty CIM. It was only when I told him that theyve already changed it twice, that he said something else clearly isnt correct here.
Any ideas what could be the cause of my issues and exactly what I can do to fix the problem once and for all?
