We've had similar problems. A few months back, after a motorway drive, EPC and traction control lights then came on. On stopping and then starting, the auto gear change was awful, with a huge thump as it changed up through each gear. Called the RAC, who after an hour (he couldn't get into the error log, tho said he should have been able to...which perplexed him), he tried a last-gasp hunch- disconnect the battery, wait 10 mins to let all electrics discharge, then reconnect (in effect a total reboot). Car was then fine...and indeed remained so for several months. Then last weekend, it happened again - this time the vehicle stuck in 1st gear, but was driveable (at 8mpg!!!). When home, I did the reboot-thing, and once again, all was cleared. It almost sounds like a software error...or some sensor that is occasionally throwing up an error that then disables the electronics controlling the gearbox. This time, I'm taking the car into the garage in the hope they can make sense of the error logs... Will report further, but someone may get a clue from our symptoms???
