Four problems related to brake antilock control unit/module have been reported for the 1999 Volvo V70. The most recently reported issues are listed below.
I just received word from a dealer that the abs control unit has failed. I was quoted approx 900 for this repair. This is not a normal wear and tear part and therefore I think NHTSA should force the question to Volvo as to whether or not this part was poorly designed and/or why do so many owners have this same problem. .
Mileage approx 115,000 when purchased now 120,000 within 8 months. Hardly hard use. Failure of ecm and O2 sensors, on two occasions the second within 1000 miles and 1 month of first repair. Caused the car to surge, if restarted might stall and generally become dangerous to drive. No warning of failure. Volvo dealerships well aware of problem and offered immediate and correct diagnosis prior to checking the computer codes, without needing much investigation. 2 dealers worked on the car one don bayer in washington and independence Volvo in charlotte. Instructed independence Volvo dealer to make car safe and roadworthy. Uploaded faults and downloaded onto vehicle, new software. Within 1 month new symptoms appear. At various times these lights show and reset abs warning, engine warning, traction control warning, speedo failure, check engine, service warning (even though service is just carried out). Symptoms include lack of throttle response when pulling away, when speedo fails. No warning of change in status means this happens during turning maneuvers with potentially dangerous or lethal consequences. Checking various sources note that abs module failure is common making the car potentially unsafe in emergency, not only for braking but during acceleration as the cars ability to pull at its normal rate is vastly reduced, adding throttle does nothing, but if the system turns back on again no warning, the speedometer just comes back to life ) this can cause unneeded fierce acceleration. I noted one death on the highway of a young woman who appeared to accelerate off the road during a benign maneuver and am concerned that this on/off speedometer/abs transmission problem might have been the cause rather than the ecm currently the focus of the investigation.
Abs control unit sporadically fails, abs and traction control lights go on notifying driver that these systems are not working. If the system fails at a critical time, could result in loss of control of vehicle.
When the brake pedal was depressed, the brakes didn't engage and the vehicle failed to stop, as a result the driver had to continuously pump the pedal to stop vehicle. Consumer stated there was complete and total brake failure. The consumer had the abs unit that was replaced. The check engine light illuminated. The dealer reset the light.
