To add to the list, terminations give the majority of CAN problems for all teams. The terminations when viewed as a load model for the transceiver chips terminates the bus in 60 ohms. This happens to be the approximate impedance of twisted pair #22 wire. When the terminations are not present as required, not only are reflections present, but the bus impedance rises to the point where the shunt capacitance starts playing havoc with rise times and noise.
Here is a TI paper on CAN...
Take a look at page 7 & 8.
