Just purchased 2006 saturn vue V6 AWD. ONLY after turning key on and backing up, when I put car in drive and turn wheel, I hear a "burp" noise in what seems to be the steering column. Was told probably ABS brakes "initialing". Noise only happens when car is turned off and then back on, and only happens once. If you are pulling into parking spot and then backing up without turning car off, the noise is not there. Is this normal? Waiting to drive another 2006 V6 to see if it has the same noise. Any ideas. Thank you very much.
