Dashboard Failed problems of the 2004 Volvo XC90

After driving for at least an hour the vehicle suddenly shuts down for a split second. All gauges go out, loss of power briefly, wipers sometimes kick on and fog lights reset and shut off and there is a thump from the transmission. This happens mainly at freeway speeds but has happened a few times at 30 mph and slower. Can happen several times on a 2. 5 hour trip. Once it happens it can happen anytime. Doesn't do it on trips around town. Called Volvo of north America and they denied any problems with the cem and said since it's an '04 with 85,000 miles that I'm out of warranty and they can offer no help.

Exiting driveway in reverse, upon switching to drive the dashboard lights started flickering and a jerk was felt in the transmission. Soon the dashboard gauges and the indicators went dead. Several error messages quickly "scrolled" (brake failure, airbag failure, abs failure, engine failure) then the check engine light came on and remained on. No power to dashboard controls (gauges dead, no lights/turn signals, no radio). Front windows work, but not rear. Vehicle drives as if in low gear. Unsafe to drive so had towed to dealer. They are running diagnostics so tbd on specific issue and cost to repair. Concerned as no recall and situation is so dangerous (what if I'd been on freeway!) Volvo should recall all the 2004 Xc90 as others report same defect.

2004 Volvo Xc90 2. 5t . . . Driving at about 65 mph with no warning aloud thump noise, windshield wiper comes on radio goes off dash lights go off, last for a sec. Then resumes to normal . This has happened several times now, while I have only owned this vehicle for a month. Today it happens again only worse . . After the initial thump and jerk it happens three more within 5 miles the last time I was going about 35 mph, big thump and jerk, wipers comes on , radio goes off , all dash lights off . . No hazards available and I get several warnings on dash brake failure , srs failure and anti skid failure. . I turn car off then back on and continue home. . . It happens again 5 minutes later at 15 mph. . . . I am reading many, many complaints like mine. This issue needs to be addressed ASAP. . I almost was rear ended twice. Volvo needs to take responsibility.

My wife and I were driving to a friend's how's when suddenly the radio started acting up ,it would go on and off . After we noticed that I slowed down a bit then all of a sudden my hole dash board went out . I tried pulling over but the transmission would not respond ,then the dashboard came back on but I had all these warnings like brake failure ,srs airbag service urgent , engine system service urgent . After all the happens the truck died ,luckily I was able to get off the road before other cars hit us . After a couple a minutes I tried turning it on and it came back on but I still had the warning lights on but the truck was running fine ,after we gotto our friends house I turned it off and left it their because I felt it wasn't safe to drive , the next morning I went over to pick up the truck , turned it on and all the lights were of and it ran fine . I looked itup online and it seems I'm not the only one who's had this problem ,it seems its happened a lot but Volvo doesn't want to do anything about it . I like my Volvo but I am also concerned about how safe it really is.

At 65 mph wipers went on by themselves then followed by split second power failure,meaning dashboard light out,hazard lights could not be turned on,windows would not open,a/c out,in the message screen at that moment antilock brake failure was displayed before everything went out,driving another 20 miles till next exit at the dusk,after pulling over and restart ( to reset) srs failure in the message screen. Car checked by Volvo dealer and statement from them:fault in cem is shutting down network and causing dim to black out. Replacement will run about $1500,this car had automatic transmission failure at 91822 miles and ignition failure recently,and many many other costly problems.

The contact owns a 2004 Volvo Xc90. The contact stated that while driving 40 mph the brake and srs warning lights illuminated, in addition to all of the dash board lights and gauges failing. The vehicle was taken to an independent mechanic for diagnosis and the contact was awaiting results. The vehicle had not been repaired. The VIN was unavailable. The failure and current mileages were 78,000.

I was driving my 2004 Xc90 on the highway when suddenly all the lights in the dashboard went out. The car slowed down. Everything electrical in the car stopped working. I could still start the car however. But acceleration wasnt the same, the car crawled. Took the car to the Volvo dealership who say this is a cem problem. A computer defect the car is barely 7 years old and this is apparently a problem with many other Xc90 owners and a real safety issue. And to replace this cemchip is 1400 dollars. Lease look into this matter.

I was driving 65 mph on the I-95 when my windshield turned on by itself, then I got abs system failure alert advising me to pull over safely. Next the dashboard died, windows didn't work and the power steering seemed to stop working. It was very scary. I got the vehicle to a dealership as luckily we were close to our destination. I turned off the ignition and explained the problem to the tech. He turned the car back on and it was like nothing had ever happened. The dashboard lit up fine and the windows worked fine. However, I did have a message stating I now had an airbag issue. They kept the car for 3 days trying to recreate what I had described and they could not figure it out. This incident happened about a year ago. It's happened no fewer than 8 times since then. I've taken it to other dealerships. I'm always charged a diagnostic fee and they can never figure out what's going on. It's very scary as there doesn't seem to be any rhyme or reason when the issue will occur. Sometimes my windshield wiper goes on it's own and sometimes my stereo flicks on and off; then I get the abs system failure and dashboard goes dead. Volvo really needs to figure this out before someone gets hurt.

I own a 2004 Volvo Xc90 t6 and it has been a disaster the last 4 years. One day I was driving on i90 (nyst) when my car whole dashboard out . It was a moment I cant forget . I couldn't do anything, I was driving 65 mph and can only force my car off the road because I have lost control of it . This is safety ?? not in my book. No one is going to do anything until someone gets hurt ? I know I am not the only complaining about this random shut down on the Xc90's . Volvo tells me they are unsure they fixed the problem . . . How can you be unsure about a safety issue that puts my life on the line . I take it to the dealer (northtown of buffalo) . They "fixed" the problem . Now 3 months later its happening again. Everytime I get in this car I am unsure if its going to happen again. I need help and many more citizens out there encounter the same situation. This is not normal . Thank you.
