Three problems related to check engine light on have been reported for the 1999 Volvo V70. The most recently reported issues are listed below.
Driving on freeway 65 miles per hour, vehicle loses complete power, ets and check engine lights comes on. I was able to coast off the freeway onto the right shoulder. Tried several restarts to see if engine will run normally, after 10-15 minutes, started car, eng ran normal, ets and cel light still on. I was able to drive home without further incident.
Malfunctioning of the electronic throttle system (ets) on my 1999 Volvo V70 station wagon caused me to lose power or stall completely while driving. It happened several times prior to having the ets replaced. It occurred for me at low speeds and in light traffic allowing me to get off the road. I was able to restart the engine after a short time interval. It could have been a major safety hazard if I had this failure at highway speeds and in traffic. This occurred several months ago and has been repaired at my expense, but on reading an associated press article today on an investigation of this problem by the NHTSA, I am submitting this as another instance of the problem being investigated. The air conditioning compressor and power windows had to be replaced. Currently, the check engine light is on.
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.
