      Door unlatches while driving

      Twice this week while driving, with top down, the passenger door has unlocked and unlatched itself. I see the warning message on the dash message screen and my wife in the passenger seat hears a ka-thunk which is apparently the unlock/unlatch. The safety latch prevents the door from swinging open but it is unnerving, to say the least. The first time was three days ago and I accounted for it as simply a door not fully closed when entering. Now I know that it is something else. Both times with top down and both times after going over a road bump. Not too much of a bump. Passenger door only. I had already scheduled the 37.5 service for tomorrow so they will definitely hear from me on this but my guess is that "unable to duplicate/no bulletin" response. I checked the web and there are only 3 other examples I could find of people reporting this kind of incident. Any ideas here?

      If you're lucky, the car might have stored a trouble code or two.

      Common known issue. I think it should be the source of a recall ... but it isn't. The dealer will "fix" it with some carefully placed grease. Happened to both of my doors at different times. After the "fix", voila!

      Yes we are, my first car was a red '68 Karmann Ghia. After awhile, my driver door was the same way.

      tarhoosier, let us know how that turns out. As you remember, yours and mine are almost identical given the mods you have done, I have 49K on mine however and as of yet no problems with the door latches but it only goes around the block once a month in the winter for the most part.

      Thus sayeth the Volvo dealer

      Service advisor says he and technician have never heard of this issue. This is from the invoice:

      Hey Tarhoosier - looky here:

      Door latch(es) replaced under warranty. No problems since then. I did get Volvo's Regional Tech Advisor involved. Good Luck!

      Looks like a common hardware component failure ... just not to the point where the door opens all the way. With all the shared parts across the line .... well ... its sort of expected we would not be the only ones. C70 probably has more chassis flew but my occurrences happened with the top up.

      About two weeks ago this door unlock and unlatch happened two times in 40 minutes during the same drive. Neither person exited the vehicle during that time, only a stop to open and close (firmly) the door. This set off alarms for me since the previous visit did not do the trick. I went to my dealer, University Volvo, Charlotte, and explained the situation. The service manager said it might take a few days and Volvocars US would be consulted. She assured me that something would happen with the car. Today I learn that Volvo approved replacing the latches on both doors. This means pulling the door panel and I am glad I took photos of the door panels before I left the car with them, just in case there is a question of prior condition. They will drive it tomorrow with top down, per the requirement of the Volvo consultant, and then I can have it Monday. Eleven days later. The XC 80 they gave me as loaner is nice but way more vehicle than I want.m I have to slide out of the seat when I exit and wait for my feet to strike the ground as I descend.
      Special thanks to Tomkat for his advice and assistance in dealing with our common issue. What can I do for you, Tomkat?

      I am certain you had either an XC60 or XC90 as a loaner, but nevertheless you have nicely articulated what I loathe about SUVs. I figure if I wanted a GD truck, I'd buy a truck -- but I hate trucks. I understand that they do have their purposes, but IMHO they should not be used as passenger cars.

      NP Tarhoosier. Glad I could help. I've had no reoccurrences since Sandberg Volvo replaced the passenger door latch on the advice of Volvo's Regional Service Technical Advisor. Paying it forward...this forum and community have been very helpful, informative and supportive.

      I'm having a chronic occurance of this now on the passenger door, three times today alone. Will be visiting the dealer soon to have it rectified. I'm not sure how much responsibility they will want to have for an out of warranty car though.

      And I have the opposite problem on the passenger door for the last 6 months. 90% of the time, it fails to unlock regardless of what I do.

      I checked http://www-odi.nhtsa.dot.gov/owners/SearchSafetyIssues for several years and other Volvo models and found several complaints. Not enough to trigger recall, apparently.
      Also mentioned several times at other volvo forums including
      http://www.volvoforums.org.uk/showth...door+latch+c70
      Plus two more comments at the first page of that UK site more recently. It is surely a design or manufacturing fault.
      I believe the safety nature of this issue is such that Volvo should resolve it. I contacted volvocars.us by email at the same time I contacted my dealer and I am sure they followed the progress with the dealer, especially as the tech left in my car (by accident) several pages of his online contacts with the volvo regional tech assistance regarding this. They first suggested aligning the door and lubricating the catch but all was well there beforehand. Replacement of both door latch mechanisms, not just the offending one finally occurred. Note that this required two weeks of time though the loaner was nice.
      As an aside, I had my car in for a service this week and the loaner was super new, 8 miles on odo and just off the truck. As I drove home I noticed the clock on the dash was wrong then realized that it was on Goteborg time. How new is that!

      Had the door unlatch issue happen for the first time today. 2010 C70 with 70k + miles. I'd like to notify Volvo so they are aware of the continuing problem.

      I'm hoping the local dealer will take care of this under some warranty.

      My entire driver side door lock assembly was replaced last week, two days before my extended warranty expired. Like I said, I got locked out of the car whereby my keyless entry failed on both doors for the first time. Usually, it's the passenger door that I cannot unlock from inside. So, not sure if the problem is related, but it's fixed now. Got a brand new loaner too. Nothing like a new car!

      Took the car to the dealer and they found no codes. They took the door panel off, and checked the cables and connectors. The also checked the striker and latches. They want me to make sure the door actually unlatches and not just throwing a warning if it happens again.

      More to come (I hope not)

      Here we go again. Passenger door unlatched while driving alone in the car. Took it to the dealer last month and they worked on it but found nothing. I guess it is time for me to call the zone rep because dealer said it would $600-700 to tear apart the door and start replacing items.

      Sure sounds like a serious safety issue to me!

      The problem is easily solved. Basically the latching mechanism is coated with a grease during manufacture that over time hardens and prevents the door latch rotating fully. The door appears fully closed but the latch is actually not fully rotated to its lock position. The fix is to simply spray a paraffin based lube into the door latch and manually work the latch til it clicks positively closed. You will need to hold the door handle open whilst some one else sprays and works the lock back and forth. I had this issue on 3 previous volvos. My car a 2010 C70 was so gummed up with grease I used almost a litre of degreaser to get the lock working again. Do not let Volvo talk you into replacing locks when all you need is £1 of paraffin to fix the problem.

      3rd time for the unlatching C70 passenger door. Volvo has agreed to cover the cost of repair at a Volvo dealer.

      I just found this thread (should've posted here instead of resurrecting that other old thread). Did anyone try this? I would think that a silicone based spray (PB blaster) might also do the trick, in if fact this poster is right (but only one post on SS...)

      I can only hope it is so simple. Yet to become unlocked (first) and then unlatched (second) suggests something more to me. I had both door latches replaced under warranty and there was no mention of gumminess etcetera in the tech notes to Volvo US service Center, several pages of which he left in my car when I came for it. This is NOT the communication that should be printed and left for a customer.

      It was for me. Happened to my wife while she was driving home the '08 M66 I picked up last spring while I followed her in the '13, then again to me on several occasions the following week (in the '08). I doused both locks with silicone spray and worked the mechanisms several times as described above; haven't had an issue since. Never been an issue in the '13, but it won't freak us out now if it does.

      I squirted a lot of silicone blaster spray into the latch mechanism in the door with the handle open and closed, and so far so good. Will post again if it resurfaces. Only issue is some dirty drip runs on the plastic skirt beneath the door, need to wash the car soon...

      Happened to me quite a few times, with both top up and down.
      Really like to know the reason.

      It's been over a month since I sprayed the latch mechanism and so far so good. I used PB blaster but I'm sure any silicone spray will work, you just need to free up the mechanism. The explanation below makes some sense to me after taking a close look at how the rotating latch and locking mechanism work. And yes, it was covered in a very dirty grease.

      I had the same problem on my rear hatch of my Vanagon Westy. Using the automatic locks would not allow the rear hatch to lock correctly.
      This went on for 2 years. I got sick & tired of this pain in butt, took the latch cover off (very easy) and sprayed silicone in the latch mechanism.
      It had solid hardened greased caked on the mechanism, works like a charm now. Concerning C70's it must be worse living in winter climates.
