1999 Volvo S80: adaptive cruise control problems

Filed Dec 15, 2006 · Brakes, Engine · AZ

1999 s80 stalled/surged at 20,000 miles at the time. *ts the consumer stated whenever the stalling occurred, the cruise control would go out, and at highway speeds the engine would start to run in an uneven/hesitation mode. The problem was much worse at lower speeds. The dealer installed two software updates at different times which did not fix the problem. Finally, the problem was fixed when the airflow sensor and the ABS control unit was replaced.

Dt*: the contact stated while driving various speeds (15-75 MPH) on normal road conditions with the cruise control engaged and after an extended ride from 45 to 90 minutes, all warning lights illuminated. The cruise control disengaged by it self and the engine hesitated. The vehicle was taken to the dealership twice, who performed a the federal safety agency recall #06v41000 which entailed upgrading the current software. However, the problem was not corrected either time, the lurch/stall problem continued. The dealership and the manufacturer coincided the replacement of the air flow control and the ABS control unit was not covered by the vehicle's extended warranty, eventhough those replacement corrected the problem. The contact was very concerned because the recall did not solve the dangerous problem. Updated 12/28/2006 -

The information panel gives the following warnings: brake failure stop safely asap (t2 goes to ------) stc service required' when this happens the cruise control doesn't work. We have called the dealer to find out what to do. He says to bring the car in when the message is showing. The message comes and goes and isn't consistent enough to be able to take it to the dealer when it is on. We were told that the brakes should work without the ABS feature. The dealer has moved to 45 miles from our house. We believe that this is a false warning.

Purchased a 1999 volvo s80 in june 2000. Since that time on dozens of occasions warning messages have constantly appeared on the dash display, I.e. Fuel filler cap loose, emission system service required, and engine system service urgent. We had the vehicle checked by volvo of annapolis for this problem and were informed that there was nothing wrong. Since then we have had the s80 checked by a reputable aaa certified auto service center who informed us that the throttle body was the cause of the problem and that volvo had to rectify the problem which is very common. When the error message engine system service urgent appears the cruise control disconnects and will not re-engage. The vehicle surges and is a constant worry for my spouse who primarily operates the vehicle.

Engine miss firing and emission light on. Later engine running good but cruise control would not work and text message 'engine system fix next service' with orange warning light on. Took to volvo dealer and they replaced the etm for no charge. They kept the old part because they had replaced the original one.

On september 10, 2005 at approximately 2:30 pm, my engine abruptly stalled while traveling at highway speeds with cruise control engaged. I pulled the car off to the side of the road. It would not restart. Upon each attempt to restart, the engine would actually run roughly for 1-2 seconds and then stall. I had the car towed about 35 miles to my volvo dealer. When it arrived, it started. This is the second time this has happened. The last time, the dealer found no problem. I am aware that volvo suspects the throttle body in these matters. Mine has already been replaced!
