I know this is an old thread but had this happen over the last few days. Picked up a Uhaul trailer and a few minutes later the fun began. Since I've been driving a couple of days without the trailer it seems to be happening less and less. I saw somewhere it could be a battery voltage issue? The worst part of it is no power steering or radio and brake lights stuck on. Any ideas?
Thanks,
Scott
