New user here, not a new Camry owner though. As per the title, I'm experiencing an odd intermittent shudder through the entire car when driving at low speed. It normally occurs between 25-35 MPH when idling along you begin to touch the accelerator. The shudder happens for perhaps a second, then the transmission downshifts and the car accesserates normally. The shudder feels like you've hit a rumble strip on the side of the highway. Started perhaps 1 month ago, but seems to becoming more frequent now. Is there any way for me to verifiy if any firmware updates have been performed on this vehicle? I'm not the first owner.

 

Call or visit a dealer with your VIN number and ask if any updates are available and were performed. They can check their computer.
