Have it scanned for codes, souns like the encoder motor either isn't working one way or the t-case module may be bad. But it needs scanning to see what the problem is.

Scannig it 6 mo ago doesnt' mean it will be good forever, it needs to be scanned or check to see if encoder motor is getting power and operating. Iit probably isn't working correctly
