Re: Electronic Speed Control
Slee,
I went through this about two months ago, and two or three others were having the same symptoms at the same time. If you search you'll find similar threads over the past two or three years. The striking similarity is that I found NO resolution in any of the threads. They basically just dried up.
Same here. It may be encouraging, or discouraging. Mine was coincidental with installation of new rear tires, slightly larger than OEM. Several run this size, and a few forum regulars told me it would not impact the speed control.
Mine did the same thing you describe - attempt to set, and then release. Over about a month, the speed at which it would hold slowly increased. For the past month or so, my speed control has worked perfectly, with no failure at any speed. I haven't tried anything outside a fairly normal range for highway driving.
I can find that all four wheels have speed sensors, so the car can tell if there is a difference in speed that it interprets as loss of traction. It makes sense that that would disable the speed control. It also certainly makes sense to me that the car could "relearn" and accept the new readings. I can't back this up - it is just the only way I can explain the behavior of my car.
I hope you'll have good success, and that you'll post anything you learn, or if the problem just goes without any explanation.
Good luck.
Michael
