Electrical System Problems of Volvo XC70

We have experienced three major defects with this vehicle. First and most concerning is the intermittent blackout of the driver's instrument panel (aka driver's information module, dim). Second most conerning is the defect in the trailer lighting control module that leaves stop, running and signal lighting on our trailer unreliable. Both of these defects appear to be design or manufacturing defects that can be corrected by upgrading the relevent parts. The third defect is in the design of the traction control system that has no physical switch readily accessible to the driver for temporary use in emergency situations, but rather is buried in the mycar software selection, labeled "sport mode. " this design requres a driver to override the traction control during the entire driving session, leaving the car without traction control when it might be needed during the same inclement road conditions that would warrant momentary deactivation of the system. Ie, in icy conditions one would want traction control on most times, but not when starting on ice or mounting snow berms at driveway exits, etc.

This complaint is for a 2004 Volvo Xc70. This car has some serious problems with its various modules. When driving on a busy interstate highway, the car jerked as if the transmission was slipping. After this a warning light stating "brake failure; pull over safely" illuminated. Car went into limp mode while on the highway in fast-moving traffic. Got car to a parking lot and waited about 30 minutes. Car started and I was able to drive it home, although being about 50 miles away. Car went in to limp more again during drive and lost all dash indicators, including turn signals, speedometer and odometer. Light for "check engine" was illuminated. After mechanic reset codes, he stated that it might be the ecm or tcm. I sent off the ecm for diagnosis and it came back without any errors. I then sent off the tcm and learned that it needed repair. After receiving the repaired tcm unit, we re-installed and car drove for a couple of days. I took the car for a 6-hour round trip drive this past weekend and had one incident of the jerking, but without any other issues. After letting the car sit in the drive for around 20 minutes, I tried starting it only to get another "check engine" light and inoperable dash indicators (speedometer, odometer, turn signals, etc. ). Took the car to a Volvo dealership today for a diagnosis. They stated that there was no contact occurring with their computer diagnostic system. They recommended a replacement of the cem as a first step with no guarantee that the problem resides in the that module. That part installed is over $1,100. This is my fifth Volvo, and undoubtedly, the worst yet. I am considering junking it and leaving Volvo in my proverbial rear view. It is astounding that Volvo has not offered a recall as this is clearly a safety hazard. Perhaps it takes people dying for car companies to own up to faulty building.

The car locks by itself automatically when key is in ignition and you step away from car leaving you locked out. According to the dealer, this is a "feature" of this car. Among all the cars I have owned and driven this is the only that does this, Volvo needs to correct his issue.

This report is for my 2004 Volvo for which I am original owner and only has 35500 miles. My seat caught on fire while driving yesterday. I got the fire out and am told that the seat warmer driver side is what caught on fire. Is there a recall for this or does it come under warranty perhaps.

The side rear l/r brake lights stay on all the time causing a safety concern, the top center led brake light continues to work normally. Tapping on the brake light relays installed in the rear electronic module causes the brake lights to shut off. "recall campaign no. 131 brake light relay" needs to be applied to 2004 models as well.

The contact owns a 2004 Volvo Xc70. While driving approximately 65 mph, there was a loud abnormal noise and the vehicle nearly stalled without warning. The contact discovered that the brake lights, instrument panel lights, and turn signals failed. In addition, the srs, check engine, and rear door car ajar waring indicators illuminated. The vehicle was driven to an independent mechanic where the battery was flushed and recommended that the valet key not be used. The vehicle was repaired, but the failure recurred. The vehicle was taken to a dealer where the rear door module was replaced. The vehicle was repaired; however, the failure recurred. The vehicle was taken back to the independent mechanic who diagnosed that the central electronic control module was faulty and needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 110,000.

After driving for about 20 minutes in 77f, sunny, dry conditions, I'd come off the freeway and stopped for about 15 seconds at a light to make a left turn. When I started making the left, someone blew through the red light to turn right coming from the opposite direction right in front of me. I let off the throttle but the throttle did not release. I was going about 15-20mph with the engine around 2,000rpm in, most likely, third gear. Since I was at low speed, I promptly tried gently tipping in the throttle to see if I could close but it did not so I immediately put the transmission in neutral. The motor revved up to about 4,000rpm which is a natural idle for this motor if the transmission is in gear and the motor is under load at 2,000rpm. After seeing it rev up, I put it back in drive and it jerked into gear because the vehicle was still on throttle. Suddenly the throttle cut and it returned to the normal pedal travel vs. Acceleration response relation. It felt as though the car had cruise control on. I could make it go faster but the motor wouldn't rotate any slower than about 2,000rpm.

Vehicle ignition assembly failed, immobilizing car. Key wouldn't move past "I" position, preventing it from starting. The steering wheel was locked and the transmission couldn't be moved from the park position. Vehicle had to be towed to Volvo dealer for repair.

The contact owns a 2007 Volvo Xc70. The contact stated while driving approximately 40 mph the vehicle lost all electrical power. The vehicle was maneuvered to the side of the road. Electrical power was restored after the vehicle was shut off and restarted. The vehicle was not taken to a dealer for diagnostic testing. The manufacturer was not notified of the defect. The approximate failure mileage was 43,400.

2007 Volvo Xc70. Consumer writes in regards to vehicle headlights and electrical problems. Consumer has additional correspondence in artemis with other vehicles. The consumer stated the rear bumper was too low, the radio would cut off by itself, the back-up assist did not work, the dashboard lights did not work to the consumers satisfaction, the throttle body needed to be cleaned and the rear tailgate latch did not work.

This 2001 Volvo Xc70 has never failed to start until this occurrence when attempted to start it chugged horribly & engine failure & engine system service urgent code appeared the car died & repeated attempts to star it failed diagnosis reveals a non-service listed issue as we have always had this car properly serviced promptly as needed. The issue is a "throttle body failure". According to the Volvo service shop this will cost me $800 to $1000 to fix!! last January I had to purchase a wire harness for this car that was $1400!! I have read many complaints on this throttle body issue and wish to add my complaint for this as well as the wire harness I paid so much for last year. For a car that costs this much and more than 50% more to maintenance than any other vehicle I have owned in 40yrs these kinds of failures should not be absorbed by the consumer Volvo should offer some kind of compensation to help properly replace these kinds of faulty systems and bear at least 1/2 the cost.

Tl-the contact owns a 2008 Volvo Xc70. The contact stated the manufacturer stereo was inoperable. The station number shows and the sound was silent. There is no static sound. The am station of the stereo was inoperable. The contact stated the station was a safety related issued, based on weather alerts and other safety alerts are broadcast on the the am stations. The failure occurred on numerous occasions. The manufacturer was notified of the issue. The approximate failure mileage was 60,000. Jb.

I was driving my 2003 Volvo Xc70 at the posted speed limit (55mph) when the dashboard suddenly went black and all of the gauges, including speedometer, tachometer, gas gauge, and clock stopped working. Every warning light lit up. The Volvo dealer admitted they had seen this issue before. The cost to replace the dim was over $1400. 00 and I had no choice but to pay it since I was not going to drive my car with no speedometer or gas gauge. The dim replacement is now only warranted for two years, so I may find myself in the exact same boat in the future if the new dim also fails. Researching this issue online, I found that this was a known problem, particularly for 2003 Volvo models. After finding the NHTSA website, I also found that someone else had recently reported the exact same problem and also noted that the dim failure could impact the proper operation of the airbag system. Clearly, this is a safety issue that is affecting more than just a few isolated Volvo owners. Volvo should assume responsibility for this problem, issue a recall and pay for these repairs. The dim module is a computer part and its failure is obviously not the result of expected "wear and tear. " instead, it appears to be a defective part that the manufacturer should replace to prevent accidents that can be caused by the sudden loss of the dashboard system and possible negative effect on the operation of the airbags. Please do what you can to have Volvo address this problem. Thank you.

Am radio quiet working several years ago. I complained to Volvo of America and I've lodged a complaint previously with NHTSA reguarding the safety factor with the radio not locking onto any am station. It is my concern that in the event of a national emergency I would not be able to receive the alert. I am, also, not able to tune to local area station for emergency traffic reports. My vehicle, with this problem, is not of an isolated condition. I have checked with a Volvo dealership and the person hearing of my problem stated that it is a common, and expensive, situation that has plagued Volvo cars. Numerous statements from fellow Volvo owners have made the same complaint on computer websites. Thank you for your time and assistance. The date below is only an estimation or a guess.

The driver information module (dim) on my 2003 Volvo Xc70 began intermittently going out. During this time, I took the vehicle to a Volvo dealer for diagnostics. The dealer informed me that the dim was bad and would need to be re-manufactured as it is a "car specific" part. The cost of the job was going to be around $1,400. 00. I could not afford the repair. Awhile later, the dim went completely out leaving without the ability to see how fast I'm driving, how much gas I have, warning lights, etc. When the dim went completely out, I began doing a great deal of research ob this problem to see if I could have the dim repaired/replaced cheaper than I was quoted by the dealer. Upon research, I found that a great number of 2003 Volvo Xc70 owners were experiencing the same problem. Many Volvo mechanics and owners, refer to this problem as not being unusual. In addition, not having a dim poses many, obvious safety hazards, such as speeding, car breaking down on the road, etc. Also, I was told by the Volvo mechanic that driving the vehicle without a functioning dim could prevent my airbags from deploying. Finally, I noticed that many owners were replacing the dim's which is leading to a number of cars that do not show correct mileage for the vehicle. Apparently, one can replace the dim with a used dim, much cheaper, but because the dim is a "car specific" part, once the dim is replaced the dim will note the mileage of the vehicle that the dim came out of. In my non-expert, humble opinion, if this problem has become "normal," the problem should be covered by Volvo; it seems that the production was faulty. In addition, Volvo should be responsible considering the faulty dim is a safety hazard.

Shortly after buying my 2003 Volvo 70xc I read that black cars have a troubling higher rate of accidents. I had unfortunately purchased a black Volvo. I noticed that there is no chrome anywhere on the body, including the rear. There are no side lights, no door lights (my 1993 has door lights when the door opens to alert other drivers that there is a door open), nothing to help with safety issues, yet they advertise as being such a safe car. Having outside indicators on a black car is safety 101. I think that Volvo should be made to add outside safety features to this model.

The 2004 Volvo Xc70 will just stop while I am driving. It has happened at least 5 times in the last 1. 5 years. There is no pattern to the problem. It is very intermittent. I was in a situation whereby I was driving 65 mph on a major NJ highway with a tractor trailer barreling down on me when the car just stopped, losing all power, - including power steering and flashers so that I can warn others of the problem I am having. Last week, I was driving on local roads, 30 mph with my child, and it happened again. The local and respectable dealership was aware of it and has tried to address the issue, but they have very little information to go on. However, the bottom line that I have no warning as to when this will happen . Did not sputter and no warning lights went on, until after the car was stopped). I am affraid to drive the car, and more importantly I am nervous about tranporting my children in it. On the whole, we love Volvo and this is our 3rd consecutive lease from the same dealership, but this is becoming a serious concern for my family. The "safe" Volvo that I bought into when I had my first child, is no longer safe.

Recently while driving my elderly mother in my 2001 Volvo xc 70 from oregon to California we had a very unpleasant experience that could have cost us our lives. All of a sudden we lost total power in 70+ mph traffic, had to sit on a very busy freeway for 2 hours in 100 degree heat (unable to run the air conditioner) unable to get out of the vehicle due to heavy truck traffic flying past us. My dear mother and I were finally rescued and towed to safety some 70 miles to the nearest Volvo dealer. There we were told that our etm had failed. I am concerned about this very dangerous problem as I have now been told that the part that they replaced (a $1200. 00 repair) is simply another of the same known faulty part. My etm faild at only 50,000 miles and could have caused a major fatality. We were really lucky but what happens next time? from NHTSA web site.

Hello, the etm (electronic throttle module) in our 2001 Volvo Xc70 failed on my wife in the middle of heavy traffic on colorado highway 83. She was in the middle lane of three and was traveling about 50 mph. The engine died completely and she had a hard time making it through traffic to the side of the road. She had to let traffic pass before doing so. She had to sit on the shoulder for about 15 minutes before the car would start again. I discussed the heavy failure rate of Volvo etms with mcdonald Volvo of denver, CO and told them Volvo was recalling this part in sweden and that at least one class action suit was filed. They said that there was no recall nor would they perform a goodwill replacement. We had to replace it at a cost of $1,090. 45. The mileage on our Volvo was 67,487. Do you have any more information regarding the safety issues and the unusually high failure rate of Volvo etms? my wife and I are concerned about our safety in our Volvo. Rurik lubinski.

My 2001 Volvo v70 cross country has lost power and stalled three times in the last month. Once as my wife and child were crossing a double set of railroad tracks and once when my wife and a friend were bisecting a busy intersection. I understand this has happened to other Volvo owners and that there is a known problem with the etm (electronic throttle module). It should be recalled. I repaired the problem because of the immediate safety concerns at a cost of $1,000.

Car stalled (power lost) several times even after driving for awhile. Stalled out at stop sign, red light, and while driving at low rate of speed. Took to martens Volvo dealer. They charged us $400+ to clean the throttle and some part near the throttle.
