Owner reports
Selected complaints filed with NHTSA by 2004 Volvo XC90 owners, lightly cleaned up (personal details are redacted by NHTSA).
On May 26, 2022, I was stuck in traffic for four hours, and the car's CEM (central electronic module) overheated causing the dashboard to shut down three times, meaning I lost all instrument readings. After each time the dashboard shut down, I had to pull over and reset fuse #27 to have the dashboard come back online temporarily. Because the CEM was already overheated due to its design flaw with improper ventilation, the dashboard would shut down again and again. A Google search would show this is a very common issue for 2004 Volvo models and before. Driving without any instrument readings is totally unsafe. I strongly urge you to force Volvo to issue a recall for 2004 and before models and fix the CEM overheating problem.
While driving on the highway "SRS urgent" text came on, also hear clicking sounds under dash on driver side, then dashboard indicator lights completely disappear (speed, fuel, temperature, etc) . Extremely hot under driver side dash. Fortunately, still able to steer and brake. This has happened twice now. Mechanic believes most likely CEM failure or DIM failure. My vehicle also has a wet A-pillar fabric (Volvo forums indicate possible cause of failure). I removed drivers A-pillar and found a clogged drain tube from the sunroof. However, did not notice any obvious signs of water inside the vehicle, though it hasnt rained for over a month when this happened.
Unknown..but water accumulated under the passenger seat under the amp and electrical components after a storm or rainy day.and its a lot of water when I brake i can hear a water fall..and water rushing and moving along the bottom. Of the car as I am steering im worried that the wiring and electrical will be damaged by water exposure the battery always dies wires soaked and sitting in water underneath passenger and never can completely get the moisture smell out of front seat area..mildew..why is this water leaking or not draining correctly ??
Unsure of what the issue is with the vehicle but smells like gas in my garage and I found a recall I was never notified about I moved from Washington to Las Vegas and never received any info regarding the fuel pump recall as well as a noise that's been going on for a year now when I drive at 60 miles an hour I've had it looked at and no one seems to know what that issue is
Instrument panel shuts down while driving on street. I believe it is the central electronic module that fails. It has happened numerous times and it is unsafe to drive without a speedometer, tachometer, odometer fuel gauge, and temperature gauge. It has now stopped altogether. Gauges just sit there and bounce
My 2004 Volvo XC90 with a 2.5t engine, 7 pass, intermittently and inadvertently stalls while driving it. It is scary because all electrical goes off, instrument panel, radio, lights, etc, several warning messages appears, such ABS, air bags failure, brake failure, engine failure, etc. It won't respond to acceleration and brakes are very hard to push, the engine does not stop. I have to stop, turn it off, wait few minutes, then start it, everything comes to normal again but with the check engine and the air bags message, then after some minutes of driving the same stalling and electrical issues happen again. This is serious because you are on freeway and you loose brakes and engine control, no information in instrument panel, etc. …
Hello Volvo, for the record, we love our Volvo SUV (2004, XC90). Over the years the service from michelle balside at Volvo on plainfield road in cincinnati has been truly excellent, her contact information is attached. However, we have has an issue since 2011 that has not been resolved, which is so uncharacteristic of Volvo. I am hoping you can help me change the outcome. For years my husbands right headlight has been turning on and off intermittently. This is very dangerous when he drives to and from work at night on an old 4 lane highway (columbia parkway) that has no separation between east and west bound lanes, which means cars travel head-on at 70 miles an hour. Our dealer looked at the issue several times and said they could not fix it; so we lived with the dangerous issue because we thought the problem was unique to us. …
I had this problem a few times a year ago and now it has returned. I was driving my car at night in the rain on a two lane freeway when all of a sudden I lost the headlights, dash lights, speedometer, radio, power windows, electric transmission, and much more function of the car. The engine is still running but it seems to almost reset or something then start shutting stuff down. I see on your website someone put this in as a complaint also this is very dangerous you cant see at night the car is hard to drive its obviously this same problem with water getting into the ECM. I read through your information and it seems like Volvo knew something was up with ones produced before or after March. It seems like they have been well aware of the problem and still want to charge you $2000 to fix it! …
Similar to many others, while driving our 2004 Volvo XC90, we hear a click, then the climate, radio and windshield wipers (if on) shut off and their display lights black out, then another click in a fraction of a second and they come back on. This was happening randomly, and nothing else was affected, until this weekend, while on a trip. We were driving on highways, outside temp in the 80's, no rain, average speed about 70mph. It happened a few times over about 45 minutes, then began happening every 5 miles or so. When I turned up the ac fan, within about a minute it clicked and we lost the usual things, but they did not come back on. …
Car lost all power and message window read "reduced engine performance". We were traveling in the left lane and had to coast through traffic to the shoulder. There was absolutely no throttle response, so we shut the car off. Upon restarting it, the message disappeared and we were able to continue our trip. It happened again, and we reset it once again. We stopped at the first Volvo repair facility we found and had them scan all the computers using the Volvo diagnostic equipment. The code they retrieved was ECM-981a. They cleared our computer using the Volvo computer, but the problem returned on our return home. We were barely able to get out of the way of a semi barreling upon us! The problem still persists, and I finally went to my computer to find some information on my own. Apparently, this is not so uncommon a problem with these cars. …
