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.

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.

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 car was going 60-63mph down the highway there was a sudden hard clunk in the transmission and my guage cluster went dead and lost all power options. Was almost hit as I tried to pull over with no blinkers, flashers, etc. After about 10 minutes I tried to start the car again and the dash came back but SRS warning was up on the info cluster. Took my car to the repair shop (authorized volvo repair) and was told there were no codes present. They drove the car for a week and same thing happened to them. They suggested that the cem volvo part number 30657629 was no good. To replace it would be 1300$ after some research I found that there are a lot of other volvo owners who have had this same occurrence, and even been in accidents due to this failure at different intervals in mileage ranging from 50k and up. Seems to me there should be a recall and some repairs made to the cem on the v70, xc70, s90, s40 etc as they all seem to do it.

Complaint centers on a 2004 volvo xc70. After a minimal amount of online research, I find that there are many owners with similar problems. Recently, after driving vehicle past initial "warm-up" stage an electronic anomaly occurs at random intervals, at speeds ranging from 1 - 65 MPH. The anomaly always involves a sudden "jolt" as if the transmission slipped, and is also characterized by various other electronic occurrences. These can include "left rear door open" light, all interior lights illuminating, driver's seat heater turning on, "SRS airbag" urgent message, "brake failure" notification, and loss of all dashboard instrumentation including lights and turn signals. Any one of these occurrences are an immediate attention-grabber while behind the wheel and create a situation detrimental to safe vehicle operation. This particular vehicle is now at an authorized volvo dealer for the second time (had to be towed the first time) for the same problem. Dealership performed software update first visit which did not fix problem. Now dealership thinks it may be central electronics module, a $1000+ fix, which may or may not correct the problem.

The events leading up to the failure of my vehicle (which has occurred 4 times in the last 9 months) are described in this volvo recall. However, my xc70 is a 2004 but is having this identical issue. (a software glitch is responsible for 11,993 volvo models being recalled by the federal safety agency. The campaign includes model year 2008-2010 s80 models, 2010 s60 models, 2009-2010 xc70 models, and the 2010 xc60, all running faulty software in their central electronic modules (cem). According to the federal safety agency, the signal from the cem may fail to reach the fuel pump electronic module (pem), inhibiting the fuel from reaching the engine even as the vehicle's throttle is depressed. Normally, this would just result in an engine that fails to start. However, residual pressure in the system may allow the vehicles in question to drive a short distance before the engine quits... And if the vehicle stalls in certain conditions, a crash could occur.) I took my car to the local dealership and was told to replace the cem at a cost of $1200.00 and that they wanted me to know that they were not even sure this would fix my problem.
