1999 Volvo S70: sudden loss of power

Filed Jun 14, 2011 · 65,300 miles · TX

The emt light came on and there was no power to the accelerator. This was quite frightening and then the power returned and the car sped up and then there was again a loss of power in the accelerator. I pulled over and had the car towed in to the shop but I believe there has been a problem with this happening to 1999-2000 volvos. My car was always serviced by the dealer and nothing was ever said about the possibility of this problem occuring.

My 1999 volvo s-70 received software upgrade code #155 in 2006 subject to recall and in august 2009 started to experience random throttle surging and loss of power ,especially on highway driving conditions(I-95), making vehicle unsafe to operate,along with intermittent ets light coming on. I am now told by dealer that cause is due to failure of electronic throttle module & not covered by 10 year or 200,000 mile warranty as "in-service" date on my vehicle was feb. 2009 and therefore past 10 year warranty period. Having researched your data base involving safety issues & accidents caused directly from this type of part failure, I am at a loss as to why a full recall has not been issued by volvo to replace all etm's on these model vehicles. I am now out-of-pocket $1200.00 for something that volvo has neglected to fix. Statistically, it appears that more of these etm's will fail outside of the volvo warranty period.

I was driving normally on a parkway in wash dc. Suddenly the engine lost power and would not go more than 10 MPH. I "limped" to a gas station and turned off the engine, inspected for loose wires, or other observable defects. When I started the car again the ets light was on and stayed on. Now the car runs erratically lurching forward or sputtering or just plain losing power at random.

1. I noticed the problem when I was driving on the highway. The car felt like it was losing power or missing like it was gong to stop running. Fortunately, unlike others, I was not stranded. 2. My 75,000 mile service was due so I took the car in for that and also let the volvo dealer know about the problem. 3. They ran diagnostics and determined it to be the electronic throttle module. They replaced the part with a new redesigned part. I do not know if the old part is available. P.s. The dealership called volvo and volvo agreed to pay for the part not the labor, which saved me about $500. That was a good gesture. 8jb

1) I was driving alone along state highway 283 in pa, which is a 4 lane (2 each direction) highway in a rural area with a posted speed limit of 65, between lancaster and harrisburg. Most traffic was trucks (tracter trailers). 2) the car (volvo s70 awd), travelling smoothly on cruise control at about the speed limit, suddenly lost power. Engine was still running, but at a much lower RPM, and running badly. Fortunately I was in the far right lane. I pulled off the road almost immediately to avoid being hit by the truck behind me. I noticed the ets yellow warning light was on. The vehicle seemed able to operate, albeit roughly, at about 30-35mph. Being in a rural area, I drove in this off the highway lane up to the next exit. I took the ramp off the highway, got to the top of the ramp, and the car seemed to be reasonable. Being in a rural area with nowhere seen for reparirs, I accelerated down the ramp to the highway, with the car seeming a bit sluggish, but otherwise ok. Then it lost power again at the bottom of the exit ramp. I pulled over, to the sound of the horn of another truck which was behind me. I shut off the car; waited a few seconds; and restarted the car. It ran much better, but the ets light was still on. After pulling back onto the highway, everything was ok for awhile, but I ran into problems when I hit some slowing traffic. When I tried to accelerate from the slowdown the car did not respond. It was as if I hadn't just pressed the pedal. I nursed it to a volvo dealership as soon as possible that day. 3) the throttle body was replaced after dealership first performed a diagnostic on the engine. The diagnostic showed 5 line items for the "throttle unit, internal fault..." I have a copy of the print out of this report. I have driven the car about 150 highway miles since the repar. The problem has not been observed during this time.
