Question about 2004 Volvo XC90

3 Answers

2-3 " water on driver's side I have a 2005 xc90 volvo.

I have a 2005 xc90 volvo. I've not had any major problems with it until a very heavy rain (and it's been through many heavy rains before this problem). There was 2-3 inches of water on the driver's floor side of the car. Any suggestions where this may be coming from? I hesitate taking it to the dealer. $$$$$ Several weeks ago, I noticed some water on the left side of the mat on the driver's side and water droplets just above it, kind of near and left of the fuse box. Help!! Rita

It the drain that goes from ur sunroof. I have an 04 and just figured it out. am a female and did it myself. It has and elbow rubber piece at the end that gets clogged and makes the water backup nd drain into the car not out. TRUST ME this is it. Pop open the grab handles on the panel next to the windshield, unbolt the bolts, pop the panle off, follow the tube down the bottom of the panel, pull it out of the elbow, pull the black rubber elbow out of the metal frame and push something into it and you will see all of the build up push out. They wanted $1000.00 dollars to do it. it is some kind of defect in the design in these trucks. u cane pour water in the lip of the sun roof where ther r 2 small holes (one on eitherside) and u will see it wont drain, but once u do this u will see the water drain out of the bottom of the truck. IT"S EASY !!! Save $1000 and do it yourself.

    Hi! Thanks for your tip on the water leaking into the floor of the driver's seat. I'm a female, as well, and have hesitated taking in my '04 xc90 because I have a feeling they'll test a thousand things and it'll cost a fortune. I'm going to take a look at it tomorrow and see if I can figure out what you did. Did you have to buy any new tubing or did you just re-route the tube to empty down to the ground? I'm a little confused on that.

    Thanks for all of your help!

I agree with the sunroof being clogged. Not only do I have 2004 xc90 by as well my oldest daughter. My husband cleaned out mine last year by doing as the above poster did and just yesterday my daughter did hers. Hers was far worse than mine and she will need replace the little elbows as they dry rotted out as this must have been going on without her noticing for some time. She is also most likely going to need to replace her yaw sensor located under the seat, pricey unit, which was sitting in water under the seat. I noticed mine because I drive barefoot at times and felt moisture. She did not notice until her car was making sloshing noises and started to smell like mold. I now plan to do this as a maintenance with oil changes.

It sounds like your windshield is leaking or your heater & A/C system is overflowing into the car instead of draining.

Seasons can cause contraction & expansion in all moving things & if the test below shows water, your windshield or door seal is no longer working.

You can verify this by drying everything up, taking a garden hose or a car wash hose & just let water flow over the windshield & top of the vehicle & down the sides including the door seal areas. Pressure isn't necessary but it may reveal where the specific leak is by making the upholstery damp & you would be able to see that from inside the car. Recheck the area you just dried up & you should find your problem. If that happens to be the case, instead of the dealer, check out the possible windshield repair services that will even come to your job or home & replace the seal or the seal & windshield if by chance it has a problem. You can get several estimates & verify reliablity before chosing a particular service.

The only other way for water to get in is through the A/C & heater system which does have a lot of water output and some drain-through when the A/C or Defroster is being used. Sometimes, the drain hose on the a/c can get plugged. It usually exits out of the heater box, through the firewall/floorboard area in front of the passenger seat area & it won't usually be a straight hose bu could be, they usually have baffles in them. Clean with a zip strip drain cleaner, or something suitable that won't damage anything as you push it up into the heater box hose (there is soft metal up there) through if that appears to be the problem. If you attempt to do this & you get immediate leakage, you've found your problem.

Good Luck

1999 volvo s70 problems What must I do to get the rain water drainage system working properly ?

Do you have a sunroof? Cars have drainage holes up there that often drain into the door jamb on the front doors and sometimes down the rear pillars and behind the trunk/boot lining and exit the car near the wheel wells. Often, the connection at the top to the pipe comes off at the top corner of the windscreen.

Others have the same problem. Sunroof drain mentioned and how to fix.

Is there a way to grease the suspention or draive shafts of my xc90?

Complaint Number: 10363820 Incident Date: October 24, 2010 Date Added to File: November 3, 2010 Description of the Complaint:October 10, 2010 purchased cash 2005 xc90 v8. Went through safety and emission service for registration-- okay. October 22 heard a strange noise from engine, called volvo dealership to request service. Didn't drive on october 23, 2010. On sunday, october 24, went out to move the car for opposite side parking and to gas up for drive to service center. Car stopped at service station, and had to be towed to dealership. Dealership diagnostics october 25, 2010 confirmed: noise is from either broken connecting rod or balance shaft....Advice to customer "needs engine" at a cost of $14,000+. The car did not come with a Warranty and even now the dealer is becoming increasingly evasive--as he says he was the owner/dealer at the time of sale, and as individual seller registered in another state and not new york, so does not have to honor Warranty or assume responsibility. Call volvo north america on october 26, 2010 with no knowledge of our ownership, (still havent received title to car). Response was --no Warranty no assistance with this counter balance or any other issue beyond 4 year/50,000 miles. Concern: before purchase when asking the dealer no mention nor when researched no revelation of the counterbalance shaft being an ongoing issue for the 2005 xc90 v8. However, further evidence clearly shows design flaws in the original yamaha engines, and a slight covert attempt by volvo to fix it via its limited edition technical service bulletin(TSB) to drill the hole in the shaft to let build up moisture escape. Additionally, volvo's second attempt to slightly address the counter balance issue is evidenced via its limited and pay-to-get TSB informing dealerships not consumers of not washing the engine, which may lead to moisture build up and total engine failure. Our attempts are now being made for volvo to maintain its slogan of "safety for life." we want the safety attribute to be effective and useful when the car is operable, and not when the car is inoperable.

2 Complaint Number: 10343465 Incident Date: June 16, 2010 Date Added to File: July 15, 2010 Description of the Complaint:Volvo xc90 2005 v8 - counter balance shaft failure leading to total engine failure and requiring engine replacement 3 Complaint Number: 10324165 Incident Date: November 16, 2009 Date Added to File: April 7, 2010 Description of the Complaint:Counter balance bearing failed at 55,504 miles. Non-greased bearing failure, caused by rusting, due to moisture build up inside of engine chamber. Vehicle had all required service done a volvo dealerships. Engine was repaired not replaced, for a cost of $5000.00. Repair work was done at volvo dealership. Volvo mechanic drilled weeping hole in chamber where counter balance shaft sits to allow water caused by moisture build up to escape. Drilling weeping hole was part of a tech bulletin issued by volvo. V8 engines for the xc90 produced in 2005 did not initially have this weeping hole in them. This design change was implemented part way through the production year (I believe post engine #6833). Letter was written to the ceo of volvo cars of n.A. Llc and representative from his office refused to provide any support, stating that the vehicle in question was out of Warranty and that there were no recalls with regards to this issue. Info provided to volvo from swedespeed.Com (see ODI id #10313311), however, this was rejected by volvo as a non-valid source of information (their own customers!). The repair job to replace the cb shaft and bearing was over 30 hours, not to mention the parts cost. What will it take volvo to admit there is a problem here and issue a recall to replace bearings and drill weeping holes in their 2005 xc90's with v8 engines? considering the cost they will incur, I'd suggest they will need to be pushed. The cost of engine repair is ($5,000) and engine replacement ($15,000+). All bearing failures outside of Warranty are falling on the shoulders of the consumer. Recalls are about safety not cost to the manufacture. Just because this problem may only be linked to the 2005 v8 engines doesn't mean it is not important enough to be addressed for not only consumer financial protection but also for safety reasons. Thankfully my engine didn't fail while my family was driving on a busy interstate!

4 Complaint Number: 10313311 Incident Date: February 13, 2010 Date Added to File: February 23, 2010 Description of the Complaint:Ungreased bearing failing on 2005 v8 volvo xc90 a balance shaft bearing is failing due to the fact that the bearing is not greased and water can enter into the bearing cavity and make it rust. Once this happens, it can produce a total engine failure, and besides the fact the engine is totally compromised and needs replacement, it would obviously impair the ability to drive the vehicle, especially at highway speeds. This particular car has an engine with only 60k miles, serviced regularly and with the last major service performed at a volvo dealer at about 50k miles. The car has been driven very lightly and it only has made about 10k miles in about two years. Here is in summary what I found about this: -the bearing that is failing is not lubricated (so nothing to do with oil in this case), and it fails due to the fact that water and/or humidity gets to it, by washing the engine(?) never did that anyway - or by the car just sitting in a lot.. -there is a volvo bulletin that details what needs to be done, including drilling a weeping hole into the engine block to drain water; this shows that the problem is acknowledged and a fix has been put into place; it also shows that there is significant number of vehicles out there that have the same issue. -this seems to be a very common problem with this type of engine and year (2005 xc90, v8 engine, engine series less than #6800) I have pointed out a few threads below that mention the same issue. Given all the reasons enumerated above, I am asking for an evaluation of this issue and I really feel volvo should recognize this as a design problem, issue a recall and step up to fix this

Front of dash leaks water when it rains on 2004 xc90

If you've had a windshield replaced take it back to them and tell them to check it out. May be improper installiation. Otherwise around the upper firewall there is like a rubber passage that is used for drainage. Remove the leaves and debris and it should be ok.

Evaporator drain problem after a heavy rain...

it is located on the right side of the vehicle very close to the firewall, it is easiest to look under the truck or underhood of the truck lower right side of firewall for a rubber tube about 1-2 inches long, find the tube and squeeze it, dirt wasps like to build nests in there, if crud runs out it should run water when a/c is on, if it is dripping with a/c on it may not be clogged, but look anyway
