The electronic throttle module on my 2000 Volvo S70 malfunctioned causing inability to accelerate. Mileage = 61,694. The ets light came on the day prior to the incident. Etm was replaced. After the etm module was replaced, the electronic windows would not function. I was informed by the Volvo technician that this was a coincidence and not related to the etm replacement. Prior to etm replacement, I had no problems with the electronic windows. Last week while I was driving alone in my 2000 S70 Volvo, the passenger seat fully reclined on its own. This incident reminded me of a similar scenario one week after purchasing the vehicle. The driver's seat fully reclined without anyone touching the electronic seat control. In December 2000, the turn signals and hazard lights switch was found to be faulty and was replaced under the warranty. Then, in may, 2001, the drivers turn signal started blinking rapidly which was replaced under the recall campaign 101a and 101b. This makes me believe my entire vehicle's electronic system was defective from the day I purchased the vehicle.

Etm or ets in Volvo S70, 1999 and 2000 makes. Electronic throttle module resulting in sever fluctuations of engine. Common in all Volvo 99 and 00 years.

Vehicle fails to maintain idle. It starts and immeditely dies. It occassionally dies while driving on highway or while breaking and preparing for a stop. . . Typically when my foot isn't on the accelerator.

The contact stated the electrical throttle module ( etm) failed. While driving the vehicle lost power. Prior to this incident the vehicle hesitated while driving at lower speeds. There were no warning lights, indicating a problem with the vehicle. The dealer replaced the etm. This replacement seemed to have corrected the problem.

Volvo 2000 S70 66,000 miles vehicle speed control after a trip of 300+ miles ets light and check engine light came on and vehicle went into "limp-home" mode [20 mph] vehicle was towed 100 miles to nearest dealer etm [electronic throttle module] tested failed and was replaced by dealer on 10/30/2005 old part not available.

The ets warning light went on two different days leading to my calling my Volvo dealer. I was told I must replace my electronic throttle module because not replacing it could lead to failure of the throttle and could lead to an accident. I had to pay $971 on October 22 to have my dealer replace the module as the car was just past its warranty.

Car began to lose acceleration on 10-15-05 and would take a full 2 min to reach 55 mph with only minimal throttle depression (any more than only the least would cause the drive train to jerk and refuse to propel the car at all). If the car was pulled over and restarted the problem would correct itself for a while (sometimes the gap in between malfunctions would be several hours initially) but would always return. Ran trouble codes and the oxygen sensor was initially faulty. Replaced then the engine would idle erratically upon startup, but after a period of time (5-15 minutes) it would all of a sudden correct itself - racing the engine seemed to shorten the time period, but you would have to depress and quickly release the gas pedal in order to get the rpm's significantly high enough to facilitate the smooth operation. Once the engine ran fine, it would operate well as long as the car was never shut off (it was ran on a journey of 1,000 miles and operated perfectly normal). The moment it was shut down, even for the briefest of spans, it would act in the same manner with the idle fluctuating wildly, but seemed to be prone to stalling when the engine was warm/hot. Volvo was contacted and recommended dealer diagnosis to determine the scope of the problem. When the car was brought in for service, I was assured that it "could not possibly be the computer(etm)". However there was a software update installed (hmmmmm. . . . . Couldn't possibly, but lets adjust it. . . . Hmmmmmm ) which corrected the rough idle initially. Only problem is now the car will not reach or exceed 4,000 rpm even with the car in park (not under load) and will stall jerk and refuse to accelerate under hard pedal pressure and will not drive above about 70 mph on the highway without protestation, loss of acceleration or jerking. All of the diagnostic trouble codes still indicate that the cylinders are wilding misfiring and I'm getting sick of trying to fix Volvo's engineering problem.

The ets system on my 2000 Volvo S70 is failing. The dealer is telling me that this will cost $1000 to fix. My car only has 62,000 miles on it, and is now stalling in traffic due to the etb needing to be replaced. This is a serious matter and could cause injury while driving. My car stalled in traffic the other day and I fearful to drive it on the highway or when crossing an intersection. Volvo needs to send a recall out on this vehicle.

Contact's wife was driving on the interstate and vehicle speed slowed down to almost no speed at all. She was able to get the vehicle off the ramp. The vehicle was taken to Volvo dealership in June of 2005 to be checked. He was told at that time the throttle body needed to be cleaned. The vehicle ran fine until September, 22,005. This time the vehicle was taken to a Volvo mechanic, the throttle body was replaced at this time. The vehicle was under warranty at that time . Then on November 12, 2005 he was pulling out of a parking place and the throttle body went out again. This, in turn, almost caused a serious accident. On November 14, 2005 he took the car back to the mechanic and he was told that the throttle body that was replaced in September 2005 was defective from Volvo. The vehicle is now at a repair shop having the throttle body replaced again. The vehicle is no longer under warranty. Updated 12/16/2005.

Car was stalling, slowing down and stopping. It was lurching forward when I stepped on the throttle almost causing an accident. The etm has been replaced once on this vehicle.

Vehicle hesitated and stalled, would not go faster than 10 mph. It happened on September 25, 2005. Dealer cleaned the throttle twice, but id did not solve the problem.

We own a 1999 Volvo S70 awd sedan. We have been experiencing difficulties related to the lack of acceleration at unanticipated times or a sudden decline in power at other times. The ets warning light is on. This unexpected loss of acceleration is especially hazardous/dangerous when pulling out into traffic thinking that you have plenty of space and time only to find out that you cannot accelerate. I have forwarded my concern to Volvo cars of America and received back a noncommittal response suggesting that we have it inspected. We did and the technician said that I should check with Volvo as there has been some discussion of this problem in the newspaper. The codes that were identified included: ecm - 914f throttle unit internal fault ecm - 9150 throttle unit internal fault ecm - 91b7 throttle unit internal fault ecm - 903c throttle unit internal fault ecm - 903f throttle unit internal fault if this is a safety defect shouldn't Volvo recall and replace this throttle unit? your assistance and response is appreciated. Thank you, will brucker note: in the section below about the vehicle it say oem yes?no (I do not know what is being referred to therefore the answer has no relevance but it had to be answered with a yes or no. ) the number of times this situation has occurred is numerous and the dates have been varied not just September 10, 2005. Thank you.

Ets failure. Had to buy a new throttle body assembly.

I just read on your website an action summary regarding "failure of the electronic throttle control module (etm)". I did experienced the same problem in sept. 2003 on my 2000 S70glt. The car suddenly lost power on the highway and slow down. I got honked by so many other drivers when I was trying to pull over to the road side. Luckily I did not get hit by any other car. The symptom disappeared after I shut and restarted the engine. When it happened for the second time later during the same week, I decided to drive to the dealer's shop for an emergency checkout. I shut and restarted the engine but still the car is shaking and could not accelerate to normal speed. So, I had to turn on emergency lights and drove very slowly to the dealer's shop. That day I spent $1,111 for them to replace the motor throttle module and it is not covered with manufacturer warranty since the car already has 78k miles on the meter. The problem goes away after the repair. However, since that time it has starting problem from time to time. It always start okay but sometimes the engine speed drop and stop after a few seconds of running. They could not find out what is wrong in the car and it is hard to reproduce the problem when I brought the car to them. The funny thing is that I just had a 105k miles maintenance fully tuned at the dealer's shop two weeks ago and they said the checking and maintenance went well and the car runs nicely. In this morning it happened again when I was rushed to work. I got stuck at my garage for 15 minutes before I finally started the engine. I suspect these symptoms are still related to this etm defect.

I own a 99 Volvo S70. The ets light has been coming on regularly. The info in the owners manual just says to turn the car off and then turn it on again and see if the light goes away. It has in the past but it's coming on all the time now. I looked on" edmunds" to see if there was a recall. . And there was nothing there. . But then I saw a Volvo owners forum and there were lots of emails about this problem. They said it was pretty dangerous because your throttle just stops working. We commute to boston everyday ( my husband does not get out of work until after 10:00pm ). . And it's very dangerous as it is. . But to think about losing the throttle scares the heck out of me. I can't imagine that happening at midnight on route 128. It would be suicide. I was unable to find recall. . But a mechanic around here told me the cost to repair is about 850. 00!l I have an appointment at a dealer on Friday. . But it would sure help to know if there was recall. Thank you for your help.

Vehicle speed control: vehicle engine dies for non reason while under way. Vehicle restarts immediately. No error code set in computer.

My 2000 Volvo S70 se looses speed and the ets light comes on. I was driving about 60 km/h in traffic and the car almost stalled without warning. . . I had to quickly stop on the side of the road (not fun!). I turned the ignition off for few minutes and the problems disappeared. Got home - told my wife what happened and she told me same happened with her about a month or more ago - but she forgot to mention this to me before (typical - hahaha). Anyway. . This problem is a safety issue and need Volvo to fix before me or my family gets hurt. . .

At approx. 80k miles, my 2000 Volvo S70 computer system began returning a check engine light along with a ets light on several incidents. When those warning lights were on, the engine would not hold a steady curb idle. Rpms wavered from 500 to 1500 and caused a dangerous surging at stop signs and stop lights. Checking the owners manual on the ets light, it said to turn the engine off then back on, if the light went out-fine. If not, go to the dealer. The incidence this happening got more and more frequest until finally the ets light would not go out and the car could not be safely driven. Researching on the internet, I found that it was a common problem with the etm or electronic throttle module, on this make and model year and that the only the dealer could replace it. So, I went to the dealer and had them replace the etm on Aug 19, 2005 at the excessive cost of $917. 91. (it was less expensive than an accident. ) even though I have not experienced the problem since, I expect that the problem will reoccur some 50 to 80k miles in the future since the defective part was just replaced with a new part with the same flawed design. I feel that Volvo should recall this part immediately and make reparations to those of us who have had to have it replaced. I feel that they knew that the part was flawed at the time of manufacture. Why else would their owner's manual explain the ets error and the temporary fix like it does? the "turn the engine off" fix just postpones the repair until after the warranted mileage has past.

Check engine light came on first week of August '05. Had obd ii code read, failure low idle. Took car to Volvo dealership, diagnostic trouble code ecm-620 idle fault, electronic throttle module is failing. I had the etm replaced. It appears from what I have read that an excessive number of etm's have failed on Volvos 1999-2001 model years and are currently under investigation by the NHTSA. I hope that this investigation leads to a recall in which case consumers that have already paid for the repair will be reimbursed by Volvo or the dealership where service and payment was made.

I first noticed my vehicle experiencing shakiness and slight stiffness in the steering wheel. Pat patterson Volvo, told me I needed some sort of air nipple replaced. I replaced it, paying better than $100. I was in the middle of a busy intersection making a left turn when it suddenly quit! it restarted. I took the car back to the dealership after it suddenly failed on several more occasions. The dealership said it was either an air intake problem they could fix for $300 or the etm (explained this was a throttle and costs $800 needs replacing) or might need both replaced costing $1100. They had to order the parts and would call me when they arrived. The next morning my check engine light came on when I started the car. I drove it back to the dealership. They told me the same thing I was told the day before. While waiting for the parts to arrive, my nephew was shot to death. With the sudden tragic loss of my 18 year old nephew, I went back to the dealership and settled for the $300 job; my financial resources after the unexpected travel expenses to the funeral, are just depleted; this car is not under warranty. That was only a few weeks ago in July. Yesterday (8/14/05) the car suddenly quit twice, and the check engine light is on again! I have not financially recovered from the funeral and repair expenses of last month! while I was in the waiting room, an older woman who was experiencing the same problem, said hers quit several times while traveling at 70 mph without warning! I heard on the news about 131 complaints about this problem. I was told by pat patterson Volvo on at least 4 visits relating to this problem that the car has an air intake problem and needs the etm replaced. They never mentioned this is a problem with these vehicles. I might not have known they were experiencing this problem with more than just mine had I not talked with the lady in the waiting room while our cars were being repaired.

While driving my Volvo S70 2000 westbound on I-90 just past the gary , in exit 10, during the morning rush hour, the car lost power and would not accelerate faster than 30 mph. Between exit 10 and the next exit 5 the road is elevated there is no usable shoulder. As a result for 5 miles I drove at 30 mph while cars and trucks approached me from behind at 55-75 mph. Numerous cars and trucks had to slam on their brakes to avoid rear ending me and one truck started to jackknife. I finally made it to the exit 5 and called for a tow truck. The dealer replaced the electronic throttle module at the cost of over $1,000. 00. I was incredibly fortunate that I was not injured or killed and that I did not cause an accident. I happened to be driving the car to the dealer to a service appointment that morning because the ets dashboard warning light had lit up. When I described the problem to the dealer the week before I was not informed that I could lose power like that . Indeed when arrived by tow truck at the dealer the service person told me that the etm problem did not make the car unsafe to drive but that "you just have to know how to drive it that way. " . The dealer is about 60 miles from my home. All the Volvo safety features wouldn't have done me a lick of good if a semi had plowed into me at 55 mph or more. This sudden loss of power problem utterly compromises the Volvo safety features. So instead of taking the Volvo on a cross-country trip this summer we rented a van. I urge that this part be recall and more importantly in the meantime, make Volvo contact car owners and tell them that if the ets light comes on the car is unsafe to drive at highway speeds.

The contact owns a 2000 Volvo S70. While driving at speed of 25-40 mph vehicle would cut out while idling or slowing down. Then it would lurch forward. The contact would put vehicle in neutral to try and keep this from happening. The vehicle is currently dealer for repairs. This has been going on since August 2005 and has been getting progressively worse. The problem was diagnosed as fluctuating idle due to electronic throttle module failure.

The consumer stated that 2000 Volvo S70 had to have the electronic throttle control module (etcm ) replaced on August 1, 2005 while driving at 65 mph. The etcm light came on, and the vehicle stalled. The consumer had to turn the car off and restart it. Before the consumer could get help the car stalled about 6 or 7 times. They had the vehicle towed to a Volvo dealer. The dealer said it was the etcm and it was destroyed. The Volvo dealer replaced the etcm, and updated the software for the consumer. The car was running better after the replacement module. This was the only time that the car had this problem. The consumer contacted the manufacturer and was advised to call NHTSA and file a complaint.

The electronic throttle system module (ets) had replaced. I had noticed the ets light cae on and then go off shortly afterward about 3 times in two weeks. The car lacked the normal power. The tachometer needle would swing back and forth as I could feel a revving in the gas pedal. I understand that had I not repaired the car, the car could have lost power completely unexpectedly.

Vehicle stalled/died, and operated poorly due to electronic throttle module failure.

Unexplained, involuntary acceleration from low speed. 2000 Volvo model S70 passenger car, awd. During a slow-speed turn the vehicle accelerated at full throttle. Impact with residential structure severed a wheel and bent the front frame 90 degrees. What happened: during a slow turn into a neighbors driveway, speed about 5 mph, turning right, touching the accelerator, the car engine accelerated at full speed. Despite foot fully into the brake the car continued to accelerate 40-50 feet until impacting the foundation of the house. Speed a time of impact 40+ mph. Tried to turn off ignition but hit house first. Considerable damage to house and car, which was totaled by the insurance company. Reported throttle acceleration problem to Volvo in new jersey, they stated no such previous complaints about unexplained acceleration. Knew of the NHTSA research into accelerator module slowing unexplained to 5 mph, but then saw a news report about unexplained acceleration and wanted to include this case in your list.

Part of 10133805, second vehicle S70, catastrophic failure, stalled while going 35 in moderate traffic. If it had failed 20 seconds later there could have been an accident. Restarted 30 seconds later in limp home mode, etm replaced. *smch.

Contact stated on 3 or 4 occasions would lose o power intermittently, usually after slowing down and accelerating. It happened about 4 times over the last year. Took vehicle twice to dealer, and they could not t find anything wrong. Vehicle will be fine for a couple of months and then it will happen again. Was able to restart the car after only a few minutes.

I have a 1999 Volvo S70. It has had a problem losing speed and stalling without warning. I had a major repair done it to fix the problem. I understand that this vehicle model is under investigation for this same problem.

Contact stated that while his wife was driving the speed dropped and the car lost power. His wife told him that a light illuminated on the dashboard before the car lost power. The car would not accelerate over 20 mph. The dealer replaced the throttle control module. This repaired the problem temporarily. But after 30,000 miles,the problem recurred. The dealer again replaced the throttle control module.

2000 Volvo S70 electronic throttle failure. The consumer stated the failure of the electronic throttle leaves the driver with unexpected loss of throttle control.

The vehicle stalled/died, an lost power due to throttle body failure. The throttle module was replaced, however the problem recurred.

: the contact stated while driving the vehicle surged and hesitated. The check engine light and ets lights illuminated. The vehicle was taken to the dealership, but the dealer was unable to determine the cause of the problem.
