Hi Sara032, did you managed to solve the problem? My Wagon has the same intermittent electrical issues. It can occur if I turn on hi-beam, am just sitting at lights and moving forward gently, even just starting the car. So many different actions cause the SRS Warning lights and tone to sound, entire dash blackout with radio shutdown and aerial up/down. You name it it has done it and no Car Sparkie can offer a solution. RAC tested battery, alternator and viewed any fault codes and could not fault anything. So hopefully you did solve you issue? Cheers Michael
