Check Engine Light On problems of the 2001 Volvo V70

7/26/07 traveling on I-77 and the car ran great. Suddenly, in same manner as car did approx 2 yrs ago on same interstate rpms dropped, car lost speed, no response at throttle, and within a few seconds we lost power, brakes, steering. Since this seemed just like 2 yrs ago (we reported this incident in 2005) we thought maybe the car will start in 10-15m. After 15-20 m of attempts where car started & immediately stalled car did start and ran fine. Since 2 years ago dealers were unable to diagnose & correct we continued to drive that evening and again the following day. The following day the car stalled again on I-? near atlanta, but this time in more traffic with difficulty getting car to side safely. Again car started like the evening before. Again-similar fuel level. We traveled 2 1/2 more hours on interstate. At destination and local dealer found no faults so no correction was made. After this 2nd occurrence we filled up more often 1/2 full or more. 2 days later and 7 more hrs on road without any problem. . As we arrive. Check engine light came on. Although car ran fine we took car to local dealer 1 hour away. They said they had a catalytic converter error but they didn't have one in stock. I told them I wasn't sure this was the problem that was causing the stalling because it stalled 2x (+1x 2 years ago) before the check engine light came on. I called my local dealer to discuss and he said he didn't think the catalytic converter was causing the stalling. Again, no definitive answers. After we left the dealer, the check engine light was off and it has stayed off. A couple of days later we drove the car 9-10 hours on the interstate to get home. Again, I kept the fuel levels approximately 1/2 tank and above. The car performed fine. We are very concerned about the stalling. When I check other complaints listed it appeared that someone else may have had a similar issue with low fuel stalling. Please don't hesitate to call to discuss.

Car's check engine light came on while on interstate at 65 mph. Drove car additional 15 minutes to get home. Followed on-dash & owner's manual instructions to get checked at earliest convenience. Car broke down next day on way to mechanic. Car bucked and surged, decelerating and acculturating without any warning. Cel came on. Display read "performance reduced". Could go no faster than 20-25 mph. In no position to stop vehicle. On busy road with no usable shoulder. Car required towing. Onboard diagnostics (obd) said thermostat was bad, but mechanic suspected failed etm. He said this is a known issue with car. The thermostat was replaced. Car was drivable. Used approximately 5 miles more. Car broke down on way home, stranding me in intersection. Same issue. Car went into "limp home" mode. Shut it off. After five minutes, car returned to normal operation. Was able to drive back to mechanic. This time obd reported tell-tale codes for failed etm. Electronic throttle module was replaced at total cost of $1200. I phoned stillman Volvo where I purchased the car. They denied knowledge of any widespread, well-known issue regarding etm on 2001 Volvos. I called Volvo America customer care and they acknowledged a NHTSA investigation underway and that they hoped to have a resolution in a couple of weeks. The representative, however, told me that it would be unlikely that I would get any cost assistance from Volvo or my Volvo dealership since I had the work done by an independent mechanic. I am filing this complaint because I did a little research on-line with other Volvo owners. I now understand that Volvo America has known about this issue for years and has not issued a recall. I am upset regarding their statement regarding independent mechanics. But I am furious that this car manufacturer would risk the lives of their customers and their passengers by failing to take action on this issue.
