Vehicle Speed Control Problems of Volvo S80 - part 2

The contact owns a 1999 Volvo S80. In 2008, the dealer downloaded the throttle software on the vehicle; however, it continued to stall and lose power while driving 30 mph. The manufacturer stated that NHTSA campaign id number 06v441000 (vehicle speed control) was closed; therefore, they would not assist. The contact will have the vehicle repaired. The failure mileage was 121,000 and current mileage was 122,000. Updated 04/24/09. Updated 04/27/09.

When driving the transmission shift slams / bucks for 2nd to 3rd gear at the 20 to 30 miles per hour. The transmission revs and then bang’s into the next gear. This also happens when slowing down and coming to a stop, you can feel it bucking / jolt (as if it was slipping) as I apply the brake. I had reported this to the Volvo dealer several times and they said that nothing came up on the codes or diagnostic equipment. I had the transmission overhauled too in April 2013 and it ran good for about 12 months and that back to same symptoms / issues. I also brought it back again around August/September 2014 time frame to have the software updated and explained the transmission shifting problem and again no fault codes. My concern is that when driving the vehicle it could be a hazard if trying to accelerate quickly or trying to stop quickly and it does not respond as it should and an accident occurs, and a possible fatality could result. I also did speak with Volvo customer services and register a complaint with them. This is not my first Volvo, I have owned Volvos since 1988. Please advise of findings and resolution.

Five lane rush hour freeway driving, 1999 Volvo S80 t6 went into limp home mode without warning. With high speed tractor trailers coming up the rear, there was absolutely no acceleration response from my vehicle. Fortunately was able to quickly push the hazard warning indicator and move over to the shoulder. This is potentially very dangerous and could have caused serious injury to myself or others. After speaking with several service managers at local dealerships, I am less than satisfied that the seriousness of this defect is properly acknowledged. According to Volvo north America customer service rep, the symptoms suggest a defective etm (electronic throttle module).

My 2000 S80 t6 stalls in traffic and loses power while driving. Whenever I stop at a traffic light, I'll have to step harder on the accelerator in order to avoid the vehicle behind me from hitting my car. Sometimes it jerks so bad I feel that engine may fall off. There's no engine light on or anything. I have called Volvo and was told the problem is etm but has been replaced on my car according to their records. I have taken the car to the dealership and had different components tested out and fixed but that did not solve the problem.

The contact owns a 2000 Volvo S80. The contact noticed that when the vehicle was at a stop, the rpms fluctuated up and down. The contact also noticed that when he did not have the brake pedal depressed to the floorboard, the vehicle would suddenly surge forward. He experienced the failure with what he assumed to be the transmission for a year before taking it to the dealership . The authorized dealer was informed about the failure but the contact was told that the repair costs would be at his expense. He called the manufacturer and was informed that because the vehicle was no longer under warranty, he would be responsible for repair costs. The vehicle was taken to a local mechanic who cleaned the throttle body. The contact noticed no problems until recently. However, the contact began experiencing the same failure. The failure mileage was approximately 80,000 and the current mileage was approximately 125,000. The consumer stated the vehicle has a defective throttle body that makes the vehicle have an erratic idle when stopped or going very slow. As a result, it would lunge forward. Updated 05/12/10.

The contact owns a 1999 Volvo S80. The vehicle first began hesitating and stalling intermittently while driving between 50-60 mph. The failure is now occurring more frequently. The vehicle has been to the dealer three or four times for this failure. The accelerator pedal was replaced twice and the throttle housing module was cleaned; however, the failure continued. The last time the vehicle was taken to the dealer, they could not determine the cause of the failure or provide further assistance. The contact referenced defect investigation number pe05041 (vehicle speed control). The VIN was unknown. The current mileage was 141,000 and failure mileage was 137,000.

The contact owns a 2001 Volvo S80. While driving 35 mph, the check engine light illuminated and the vehicle shut off. The vehicle was towed to the dealer and they refused to diagnose or repair the vehicle. The vehicle was towed to another Ford dealer that will perform the repair. The contact stated that the failure has occurred before and she believes that the cause is the vehicle speed control, which is currently under NHTSA recall number 06v441000. She also stated that the radiator was replaced at 28,000 and 56,000 miles and currently needs to be replaced again. The contact stated that the radiator fails every 28,000 miles and the engine coolant light illuminates. The purchase date was unknown. The current and failure mileages were 87,000.

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.

The car hesitates when pressure is applied to the gas pedal, and in order to speed up the pedal has to be pushed again. I have complained to the service department several times. The second time I complained the service manager drove the car and said it the way the car was suppose to be, the computer system worked that way. I brought it back in with the same complaint and they said other cars had similar difficulties, and they replaced a computer chip. The pick-up was a little better but still not like other cars. The latest failure occurred as I was taking a left out of a driveway. I put my foot on the gas, nothing happened and I put my foot on the gas again, at which time the car sped across the road and hit a telephone pole.

I'm a new owner of a 2001 S80 t6 with 66k miles. Second day of ownership I'm on my way home in the passing lane of a freeway in MA, traffic slows to a stop. As I accelerate the car stalls. I pull to the left of the traveling lane, put the car in park, restart the vehicle. The next day, I pull up to a red light, accelerate and the car stalls. I put it in park, restart the car, and away I go. No messages, no check engine, no codes that I know of. I travel 100 miles a day, and the problem occurs at least every other day. This problem in intermittant and extremely dangerous. The highway I travel on allows travel in breakdown lanes during rush hour. I need to travel in the right travel lane always in the event of another stall. Dealership cleaned the electronic throttle module. Problem continues. Returned to the dealership. They say, "no codes, no new throttle". That's the Volvo policy, gallo Volvo, worcester, mass. Lou is the service manager. How many times does my car need to unexpectedly stall before my car shows a code so I can repair my faulty etm? it's dangerous to my family and me.

We began reporting problems with hesitation and surging in our 2001 S80 t6 several years ago to the service department at our nearest dealer, sill terhar motors in broomfield, colorado. They tried replacing a turbo valve and a software upgrade that was available at the time, and we were told that using the highest octane fuel would be necessary in order to prevent the hesitation. The problem continued. Given the inconvenience of the dealers location and that they had not seemed to be able to correct the problem, we had the vehicle serviced for a while at an independent Volvo mechanic. Last fall the emissions and check engine warning lights turned on, and they replaced an oxygen sensor and/or mass air sensor. The warning lights turned on again, and they recommended that we go to the service department at the dealer. We learned of the "extended warranty" Volvo was beginning to offer as a result of the problems in the design of the electronic throttle module. In early December we left the vehicle with the service department at sill terhar, and they did the software upgrade. Within days the vehicle was running horribly and was stalling in intersections. Sill terhar had the vehicle towed and reported that the problem was due to a hose that had not been fastened securely. Due to travel during the holidays and the multiple snowstorms in colorado in late December, we drove this vehicle in early January after having put only about 100 miles on the vehicle since the time that it was reportedly fully cleared of problems with regard to the etm, the check engine warning light turned on again. We returned to sill terhar, and they said that the problem was due to a faulty right front oxygen sensor. They were certain that this was unrelated to the etm problem. That most recent work cost us $400. We picked up the vehicle last Friday evening and, today, only a few days later, the check engine warning light has turned on yet again.

Approximately 6 months ago vehicle began erratic throttle while on speed control (surging). Dealer serviced vehicle with software update and temporarily resolved problem. Problem has returned as well a spontaneous stalling, and very erratic variance in throttle pedal position and acceleration. Stalling has occurred with throttle pedal release entering turn lane - no power steering nor brake boost. Dealer has serviced vehicle - cleaned sensors related to throttle position module - with no improvement. Wife is refusing to drive vehicle she now refers to as scary.

My 2001 Volvo S80 etm (electronic throttle control) failed, this caused a sudden loss of engine, steering, breaking and headlight systems.

After Volvo performed their recall on my second failure electronic throttle module in April 2006 my cars stalls while driving without warning. At this time Volvo replaced the failed etm and loaded new controller software into my car. In may 2006 I returned my car to Volvo after 3 stalling events in one week's time, they told me the car set no codes therefore they could not help me until they car told them what was wrong. The problem did not reoccur again until July 8th. At this time I was driving with my family in the car and in a rolling backup at at 30 mph on I-95 in delaware. The first time was on a downhill section and I was able to restart the car without the car slowing down. The second stalling failure occurred with no warning other then the dash indicator lights coming on, on an uphill section with an semi following directly behind me. In the case also the car immediately restarted, however if this had not been the case my car and family would have been rear-ended by the semi. It is my understanding from research on the internet that the programming changes made by Volvo make it more difficult for the etm to set a odi failure code. If this is the case, it may become impossible to determine an etm failure even when this failure results in an accident. The car is scheduled to be looked at on July, 21, 2006.

Just after entering the highway and attaining highway speed my 1999 vovlo S80 lost power and had to be coasted off the ramp. The emission service warning came on and the vehicle was idling very rough. The car was towed in to a repair shop and the computer codes indicated the throttle module had failed. After hearing that their was an extended warranty issued I checked the website and learned that this had happened to others. Fortunately this power failure occurred while in the rt hand aloowing the vehicle to safely exit the hwy without incident. Had this loss of power occurred in ione the interior lanes then this incident would've ended in a collision and most likely resulted in injuries to my family. This condition warrants an immediate recall.

2000 Volvo s-80 t6 , etm part replaced in Dec 2004, in conjunction with complaint number 10145678; returned car to dealership on Saturday 5/13/06 to have software recall upgrade performed due to same conditions as present in 2004 incident - vehicle stopping unexpectedly in traffic. Car since Saturday has continued to stop in traffic 5 times, car was returned to service, now the service department is saying the etm is ok , but I may have to pay to have the problem diagnosed- and could be another malfunctioning part that they did not inform me about on last service visit. They are expecting me to pay for part and labor replacement - which I believe is still in conjunction with the malfunction of the etm. My wife and family are afraid to get into this car.

For the past year my check engine and urgent light have been popping on. I have to go to my machanic (who is Volvo certified) to have them turn off. But the check engine light comes on more frequent now. For the past 6 months, when I start the car, it hesitates and runs rough, like it is going to stall. The first time this happened my machanic said it needed a tune up. Today 10/19/06 I brought it to my macanic again, and they told me it was the throttle module and the 1999 S80 's are having all the same problems, and that I need to take it to an authorized dealer, before it gets worse.

My 2000 Volvo S80 t6 stalls (typically in junctions) after 120k maintenance service / recall 155 etm software upgrade. The service was performed on 5/12/06 at authorized Volvo dealer (128volvo. Com). Since the service, the car stalled 5 times, and has been to the dealership three more times, without a fixing the problem. The dealer rejects my complains and wants this issue to "happen more frequently before taking action". Sudden stalls almost lead me to a traffic accident already at least once; the dealership isn't concerned about traffic safety.

A 2000 Volvo S80 t-6 would on occasion change speed and jerk without warning. The problem initially was sporadic but became increasingly worst over a period of three weeks. A Volvo dealership checked the vehicle and found the electronic throttle module was bad and needed replacement. Repair cost exceed $1,200. Ouch.

I have a 2000 Volvo S80 t6 with several etm or throttle control failures. I have had ist serviced twice and it continues to fail. My neighbor has the same problem. The vehicle stalls inadvertently and has stranded me in the middle of traffic where I narrowly missed being hit by a tractor trailer. My wife also was almost hit while making a left hand turn and stalling in the middle of an intersection.

: the contact stated the vehicle lurches forward and stalls. The vehicle speed is 25mph and below when the stalling happens. It was taken to the dealer for inspection and the etm was diagnosed as the problem. The etm was replaced; however the problem still occurs. The performance reduced lamp illuminates each time before the vehicle stalls. The vehicle is currently at the dealer for additional testing.

After reporting several problems traced to emt malfunction I had to pay out of pocket in excess of $800. 00 to have emt replaced in 11/2002. Less than two years after that, I've experienced the same problems listed on previous complaints, to the point where I consider the vehicle unsafe. I have experienced no less than 15-20 incidents in the past 6 months alone. The last one being just yesterday where the vehicle all of a sudden stalled down to about 20 mph on the highway for no apparent reason and then back to normal speed several times.

Vehicle stall without warning. Almost cause an accident. Dealer refuse to acknowledge the problem and stated that every is fine. Send me back without any work done.

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.

Vovlo S80 2000 model year; car independently accellerated while being driven the car surged when in idle, then when put into drive, it suddenly accellerated without my pressing the gas. I was able to stop the car using the brake. When I took my foot off the brake, the car again accellerated. I stopped the car again, and when I took my foot off the brake it accellerated a third time. I turned the car off. As I was in an open parking lot, I turned the car on again to see if the problem was repeatable. The car again surged in ide, then accellerated soon after my putting it in drive. I turned the car off and on again, and the problem repeated a third time. Forty-five minutes later, the car was started without incident. It was brought to the Volvo dealer, where the mechanics repeatedly tried to duplicate the problem without success. We left the car at the dealership for eight weeks, basically refusing to pick up the car until they found the problem and corrected it. Volvo had a specialist look at the car, and the specialist was ultimately able to duplicate the problem. The specialist noted that the car was increasing, instead of decreasing, rpm's as it came to a stop. They cleaned the throttle module and updated the software for the throttle mechanism. We looked into Volvo's known problem with this model and found that the electronic throttle module (etm) has frequently failed, causing cars to stall and accellerate unexpectedly. We obtained the service records of our (recently purchased, used) car and found that the etm had already been replaced due to problems reported by the previous owner in 2003. One week ago, when the car stalled. The incident date entered below is approximate, but I can find out the exact date if that would be helpful.

In August 2005, we took our vehicle in for routine maintenance at 67500 miles. I am the primary driver of this vehicle and had noticed some problems which were discussed with the service department. This vehicle had stalled at parking lot speeds and it had been sputtering at take-off. My husband presented the service department with a publication from the highway safety board which discussed a problem with the throttle body on the Volvo S80. As we were having the same problems described in this publication, my husband asked the service department to replace the throttle body on our vehicle. The service department was aware of the problem but as Volvo had not issued a recall, they were not authorized to replace this without the Volvo warranty company reviewing this issue with our vehicle. The warranty company did examine our vehicle, but declined to replace the throttle body at that time. On December 11, 2005 my family (husband and two children, ages 2 and 10 months) were traveling home to the atlanta area from nashville, tennessee. While driving this vehicle, I noticed that it began to accelerate and decelerate and then completely lost power. We were traveling on I-75 south at interstate highway speeds and were able to get to the shoulder of the road when this happened. Unfortunately, we had to pull over onto the left shoulder as the two right lanes were in a construction zone. We were then endangered by traffic merging to the left which in some cases attempted to pass on the left shoulder. We had to have the car towed to nalley Volvo in marietta, georgia which was approximately 34 miles from where we originally broke down. As this happened on a Sunday evening and no rental car businesses were opened, we then had to get a taxi to take us the rest of the way to our home. On Monday morning, my husband spoke with the service department about what had happened. The problem was diagnosed as a defective throttle body.

My 2001 Volvo s-80 suddenly lost all power and came to a stop and would not restart. This occurred in sept. 2003. The dealership, beach Volvo in myrtle beach, SC, wanted over $600 to repair the auto since it was beyond the 50,000 mile warranty. It had 60,000 miles at the time. After a lengthy discussion with Volvo America, they agreed to split the cost between myself, the dealership and Volvo America. The electronic throttle body was replaced. On 12/05/05 the same thing happened. The car now has 82,700 miles. It is being looked at by beach Volvo at this moment.

The contact states was driving on the highway when the car completely stalled, resulting in loss of power. The warning lights came on prior to the car stopping. She reported having no problems prior to this incident. The vehicle was towed to the dealership, and they stated to contact the NHTSA hot line services and file a complaint. The cause has not been determined.

2001 S80, multiple failings of the electronic throttle module. This has happened repeatedly over the last 2 weeks. Too many times to count. Car w/o notice will not accelerate beyond 20 mph, idles roughly. Has almost caused several accidents.

Vehicle stalled at 45 to 50 mph. Made several attempts to get restarted. Replaced electrical throttle module (etm) and it fixed that problem.

: the contact stated while stopping at a red light the vehicle stalled with no warning. The engine was restarted and again stalled. The vehicle was towed to a local dealership where the vehicle was inspected. The dealer determined that the throttle body needed cleaning and the software updated. After the repairs were made the vehicle was sold.

I own a 2001 Volvo S80, 4 dr. Sedan which I am in the process of trading in because on 3 different occasions this year (2005) the car stalled, the last time I needed to have it towed. After doing some research I noted that Volvo had reached an agreement regarding complaints filed in California about the etm module. I believe that was the cause of my stalling. I did have the part replaced, at my expense and the mechanic showed me the part that would not stay closed consequently causing the car to stall. At no time was there an indication that there was a problem - no warning light. While I love the car, I don't feel I can trust it even though a new part was put in. According to the Volvo dealer, part would not be replaced unless warning indicator came on. The last time the car stalled was thanksgiving night.

2001 Volvo S80 t6 1. Failure vehicle speed control/electronic throttle control module 2. Transmission failure - gm transmission.

Vehicle repeatedly stalls at low rpms, decelerating, or coming to stop at traffic lights, off-ramps, toll booths etc. Problem is intermittant, and doesn not yield diagnotics on consistant basis. Dealers refuse to follow-up on problem as diagnostics are inconsistant. One injury avoiding oncoming vehicle upon exiting stalled vehicle. Injury minor, and treated locally.
