2000 Volvo S70: hesitation when accelerating

Filed Jun 25, 2013 · Acceleration · 153,000 miles · TN

Purchased vehicle used several weeks ago. While performing fine during test drive, within hours vehicle developed issue where it attempts to surge forward while braking (at stop light, in driveway, etc.) which has almost caused numerous accidents. Other times, when pressing the gas pedal, the car hesitates and almost stalls before accelerating, causing dangerous conditions at highway speeds. Brakes inspected and are perfect as is fuel pump, fuel injectors, engine, etc.; mechanic suggested that this is related to a recall volvo issued in 2006 regarding the electronic throttle module. Volvo informed me that it is no longer honoring this recall.

Tl*the contact owns a 2000 volvo s70. While driving 65 MPH, the vehicle decelerated to 15 MPH (at the lowest). The contact frequently noticed the failure and also observed that the tachometer would fluctuate up and down. She took the vehicle to a mechanic, who retrieved an error code and referred her to the dealer. The dealer retrieved the failure code for the throttle positioning sensor. The contact was informed of the federal safety agency campaign id number 06v441000 (vehicle speed control). She consulted six different dealers and they all stated that the parts needed for the repair were on backorder for approximately six weeks. The closest dealer informed her that they have yet to receive parts, even after the six week deadline. The manufacturer could not provide any additional information. The current mileage was approximately 90,000 and failure mileage was approximately 40,000.

**approx. Incident date is actually ongoing for past four years.*** I have a 2000 volvo s70 which I purchased new in may 2000 from volvo athens, ga. Dealer. I currently have 190,000+ miles. Over the past eight years I have owned the vehicle I have had consistent problems with the etm situation. At first, being new to volvo cars and repair situations, volvo denied the etm problem and stuck it on me to be repaired in nov. 2004. Not until I described my issues with engine failure to an independent mechanic, was I warned about the ongoing problems in my model vehicle. Since my initial repair I have encountered four other time periods when the same etm situation begins occurring, typically 20-30,000 mile intervals since the lasts service of the specific etm defect. Now, I am on my fourth trip in four years to the local dealer to once again have the etm situation repaired. I am at 190,000 miles and according to the manufacturer "extended warranty" on this problem, my ability to have this ongoing safety issue fixed at manufacturer costs will cease in approximately 10,000 miles. Clearly this safety defect has been an issue with my model car since its manufacture by volvo and to date no effective remedy has been found. I feel this issue is a major safety defect as my car will stall or hesitate then surge at any given moment thus causing a potential traffic accident involving not only myself, but my passengers, and potentially other drivers on the road. I am sick and tired of volvo not taking more responsibility for this issue and finding a solution to the problem, not just a stop gap measure to appease the federal safety agency. I have never been contacted by the federal safety agency regarding this issue despite my ongoing complaints to my local volvo dealer as well as the manufacturer service center. It appears from documentation on this website that the federal safety agency has gathered, or attempted to gather, complaints on volvo etm matter and I want to be included in such complaints.

Vehicle surging forward without accelerator input roads wet, but not frozen (luckily). On making turn in residential neighborhood, volvo s70 surged without accelerator input requiring driver to take corrective action and brake hard. In 2005, this vehicle experienced engine stall, vehicle hesitation upon acceleration. Vehicle hesitation was consistent at approximately 2100 RPM at freeway speeds. On taking it to the dealer they reprogrammed the etm. After this repair, within days, the veehicle experienced and sudden and unexpected transition into reduced performance operation (limp mode) while driving on the pa turnpike. Dealer instructed us to bring car in where they installed a new etm and reprogrammed it with the new software upgrade. After further negotiations with the dealer, the cost of these repairs were reimbursed by the dealer in an agreement with volvo (so-called secret warranty). Note that this occured prior to the settlement in california. Volvo would refer me only to the dealer, and would not discuss the possible problemn with me. I believe that we have previously had the etm cleaned when we had similar problems in the past. The current surging and hesitation at freeway speeds (2000-2200 RPM) and the surging with accelerator inputs are happening with the new etm that is only about four months old in the vehicle.

Vehicle exhibits "hesitation and stuttering" during both acceleration and maintaining steady speed. Ets warning light has appeared and then reset twice. Tune-up and fuel changes were tested with no change in issue. Ets warning light and on-board diagnostics indicated electronic throttle module failure and required replacement. I have the old part and the diagnostic printouts. After researching this issue, it appears that this is a common and premature failure item on volvo cars from 1999 thru 2001 model years. Since this is a critical sfaety component that can fail without notice (at the worst possible time), it should be as reliable as other critical componeents such as the ABS or SRS/airbag systems. This does not appear to be the case.

Speed control. Have had a variety of speed/engine control problems. Engine would die. Engine would cause "bucking". Engine would not accelerate. Throttle body and air mass meter replaced. Throttle body covered by warranty but I had to pay for air mass meter replacement. Current problem traveling @ 55 to 60 MPH press on accelerator and car will not accelerate but will slow down with rpms hesitating at 5000 and 4500 without accelerating. Car slows down,loses power. This occurs usually under a hill climbing situation but has occurred on flat terrain. In hill climbing once more gradual slope reached, car accelerates.*ak updated 01/03/06.
