I own a 1997 Volvo 850 glt. It has a problem with the abs computer, according to the dealer. When I purchased the car I got the extended warranty and took it in with this problem with 10,000 miles remaining on the warranty and was told that it was not covered. After further investigation and several calls to customer service reps I was told that when I bought my extended warranty that it was not covered but is covered now, for the same exact problem.
Abs/tracs module defective.
1996 850 Volvo wagon abs brake failure. The abs brake computer periodically turns itself off (the abs dash light comes on). This wouldn't be too bad because the brakes will work fine even if the abs system malfunctions. Except when the system first malfunctions. There is a one to two second interval when you try to apply the brakes and the pedal fights you, vibrates, then allows normal braking (not to be confused with the abs chatter that happens when it is working properly and a wheel is slipping). My abs system turns off every time I drive the car, you're just never sure when. If it does when I'm braking, my braking is impaired for a couple seconds - that could be catastrophic! my Volvo dealer says they've had a lot of problems with these "computers", but it doesn't affect safety. Furthermore, it costs $700 to fix! I believe this is a safety factor and I'm appalled that Volvo (of all companies) doesn't issue a recall.
