The vehicle sporadically surge/hesitate and stalls at low revs. This started maybe about half a year ago and has gotten worse with the problems even at high revs. The problem culminated on may 17th 2009 or there about when I nearly got into an accident. I was traveling on the middle at about 60 MPH and there was a slower vehicle in front of me. I accelerated to try to pass the vehicle on the fast lane. The vehicle did pick up and all of a sudden went on a limp mode even I stepped on the accelerator. My vehicle was almost just side by side to the slower vehicle when this happened. The next thing I heard was a loud continuous horning and screeching of brakes of a car behind me on the fast lane.. The vehicle is well maintained and perform service well above as what manufacturer recommended. Based on various info. Sources, the problem is almost identical to car that has an electronic throttle module problem.

Tl*the contact owns a 2000 volvo s80. The contact experienced two failures listed as recalls for the suspension and vehicle speed control. The manufacturer stated that his VIN was not included in the recalls. He is very upset with being excluded from the recalls because the failures are identical. While proceeding to make a left turn at approximately 5 MPH, the tire detached from the front driver side of the vehicle. The contact felt that this was a very serious safety hazard. The vehicle was towed to an independent mechanic and the wheel axle, lower control arm, and upper ball joint were replaced. The contact also observed the failure of the speed control mechanism. While driving between 55-60 MPH and applying pressure to the accelerator pedal, the vehicle decelerated and hesitated. This failure occurs only during highway driving. The vehicle has not been repaired for this failure. The recall numbers were unknown. The failure mileage was 53,000 and the current mileage was unknown.

My 2000 volvo s80 has failed to accelerate properly. In idle, it sometimes works fine, but at other times it idles erratically. Several times recently, I've needed to accelerate quickly, but the car hesitated and displayed the check engine light. A few times, I attempted to accelerate anyway, and the light would begin to blink, and the car would still sputter. This created a dangerous situation for me and my family. I had the spark plugs replaced but that did not fix the problem. I learned recently that this is indicative of a failed etm (electronic throttle module), which has been an issue with this model car.

No attempt to solve complaints by dealer, contacted volvo customer service and they declined to discuss problems, they declined any further involvement. Car had salvage title 2+ years ago from minor accident which prematurely deployed air bags, repaired and returned to service. I am retired ase master mechanic, service manager, and sae member, this is not a transmission issue but caused by the erratic actions of the throttle body system and module. Transmission passes all conventional tests. Results stuck in gear can be corrected by cycling the ignition switch off and back on. This can be done by pulling to the side of the road and stopping to cycle the key or traffic permitting placing in neutral and restarting and then back to drive. No observed failures above 65 MPH. Tsb send wrong signals to "network" are translated as instructions resulting in poor fuel consumption, high emissions, abnormal wear and tear on transmission, ignition switch, starter, and related components for normal operation, plus a dangerous driving condition.

In early jul 05, I experienced electronic throttle system (ets) problems with my 2000 volvo s80. Particularly concerning to me from a safety standpoint was that several times, including when I was in highway driving situations, the car on its own suddenly accelerated and decelerated, hesitated on acceleration or would not accelerate, and displayed engine stall symptoms. The computer indicated degraded engine performance (limp mode). I lined up a service appointment with lovering volvo of meredith. After lovering's first attempt at repairs, the car was still not operating normally and I took it back to the dealer a second time. I paid a total of $2,074.42 for repairs, $1,741.44 the first time and $332.98 during the second visit. In accordance with a june 2006 volvo letter, I took my s80 back to lovering for inspection and ets software upgrade. I submitted to volvo a claim for reimbursement for ets repairs. The advertising checking bureau (acb), which administers the ets warranty rebate program on behalf of volvo, sent me a check for $747.93 for the ets repairs. Acb said it was authorized to reimburse me only the $587.93 cost of electronic throttle body, electronic throttle module reload, and gasket, and associated $160.00 labor cost. Acb advised me to contact the volvo customer care center. A volvo customer care representative confirmed that acb had done as instructed and suggested that I take up the matter of the remaining repair costs with lovering. The lovering invoices, dated july 26, 2005 and august 8, 2005, indicate that a $295.65 portion of the initial $1,741.44 repair bill had to do with totally unrelated steering/suspension and engine mount repairs. Still questionable in my mind are the oxygen sensor repairs which added up to $897.86 and the subsequent mass air flow sensor repairs which came to $332.98. I suspect the problems are all ets-related and I am currently pursuing the matter with the dealership.

In july I was traveling in traffic at idle speed when my car started to surge then stalled. I was able to restart it, however I had to keep one foot on the gas and the other on the brake to keep it running. I was able to limp it home using this method to keep the rpms up. When the codes were read it said the 4 oxygen sensors were out of range. I tuned up the car, cleaned the throttle body and oxygen sensors and reset the codes. (65,000 miles) after this the car seemed alright until around 79,000 miles. My wife and I were on rte. 1a on the maine coast in traffic . While going around a sharp curve the car stalled. I lost control of my steering and brakes and the car nearly went over the cliff into the ocean. I was able to get it under control and the car restarted with the idle surging. I limped the car home using the gas and brake method. At intersections if I let the car idle the car would surge forward then stall. My mechanic read the codes and told me the map sensor and o2 sensors were bad and replaced them. This seemed to work for a while, however the car reverted back to the same problems. I finally called gallo volvo who had serviced my car under warranty until 60,000 miles and the service manager told me that this was a known problem covered under a hidden recall. Once a customer complained they could fix it. I brought my car to them and they reprogrammed the computer to "repair" the problem. My car no longer stalls, however it surges and hesitates upon acceleration nearly causing people to hit me in traffic. I am still trying to resolve this problem after over $1800 dollars in expenses, multiple near accidents and numerous hours of my time.

My 2000 volvo s80 2.9 vehicle started surging then hesitating, back & forth, at all speeds up to 70 MPH interstate speeds while cruise control was on and off. When cruise control is on, after about 5-10 miles, cruise control turns itself off & car suddenly starts decelerating. After about 1 week of this, on 6/30/06 performance reduced message appeared. On 6-24-06 engine service required message appeared for a short time. After stopping and turning motor off for about 30 minutes to read owner's manual, started motor again & message has not reappeared. When cruise turns itself off, you cannot turn cruise back on until motor is stopped & restarted, then you can turn cruise control back on for about 5-10 miles then it will go back off. Surging and hesitation continues with steady pressure on accelerator (trying to maintain constant speed) and cruise control off.

I have been having problems with my 2000 volvo s80 hesitating as if it's not getting any gas when first beginning to drive it everyday. I have complained about this problem since purchasing this vehicle but the volvo repair shop have not been able to fix the problem and they say they do not know what the problem is. Also my check engine light, stc light, and ABS light keeps coming on. I have also noticed that when these lights come on my car becomes hard to steer sometimes. After checking into this problem I have found that many other volvo s80 's built around the same time as mine are having the same problems. I have complained about my car suspension making weird noises since having this vehicle and the volvo repair shop says they can not find any thing wrong but when enquiring with others who own volvo s80's, built around the same time as mine, many are saying they are having this problem also. The below information asks for an incident date but the problem with my 2000 volvo s80 hesitating and being hard to steer occur often probably over 100 times.

I read recently of your inquiry into a stalling problem with certain volvo models. I had that problem with my 2000 volvo s80. For no apparent reason, the car started stalling without any warning. Sometimes it would restart immediately, sometimes not. I managed to figure out that, if I always kept the engine revs up (meaning I had to always have my right foot on the throttle and keep the revs above @1500 RPM), I could prevent the stalling most of the time. I called my volvo dealer, betten imports, who unfortunately is 120 miles away in grand rapids. I was able to drive the car there, but it was a long, nerve-wracking trip. They seemed to be familiar with the problem and replaced the throttle body under warranty. My concern, after reading several articles being reported in the online press, is that other people who have had this repair have experienced a re-occurrence of this problem. In recent days I've noticed an unusual "hesitation" under mild acceleration sometimes, but nothing worse - so far. Below, the "number of failures" is a best guess on my part. Also, the "incident date" I've used below is actually the day the dealer repaired the car, as I don't have a record of when the problem actually began. It had been going on for several weeks before I could get the car repaired, though.
