I have an '01 Montana long wheel base. Bought the van 1 year ago no problem. Now when exceeding 75 (common on I75) I will receive an intermittent overspeed warning from the message center. No codes. Dealer shrugged. The only documentation that I can find is from a caddy posting referencing speeds over 75 sending a warning to the message center. Noticeably there are no performance problems. RPM's are steady. Any ideas?

I'm just going to take a guess here, but I think it's GMs way of telling you to slow down when you hit 75+.
Well hopefully they disable that in States, like Arizona, where 75 is perfectly legal on (e.g.) sections of I-17.
Q to th OP. EXACTLY what is the message, btw? GW
Kind of like an updated version of the Speed Alert Buzzer on my 68 Buick.
Set a needle pointer to any speed and once the speedometer needle hits the other needle______bbBBZZZZZZZZZZ.

It's a GM inspired safety thing. It goes along with the GM headlights always on and the inability to hang an arm out the window of a GM car.
