Hello.  Newbie member here... I am hoping all you smart folks can help me with a problem I am experiencing.

 

I have a 2015 R-Line Tiguan — I bought it used in September.  It is my second Tiguan (first one was a 2009).

 

I live in the NorthEast US, and started having issues with my trunk latch not opening when the temps drop below freezing.  When it warms up, the latch works.  I confirmed this with one of the local VW dealerships/service departments — and also by using a hair drier to warm it up.

 

The service department said they could replace the latch, but that would not guarantee fixing the problem.

 

Has anyone else experienced this issue — of the trunk latch freezing?  

 

 

 

Thank you!

Welcome.

 

I can't say it's a common thing, but stuff does happen. Either the latch is faulty, or perhaps the previous owner decided to lube everything with WD-40, which will wash out all the grease and allow water to enter and subsequently freeze. Have you tried some spay lube that is not silicone, or while lithium?

Yup, had it this morning, -3°. Maybe because of the kind of switch, it seems more pressure then movement activates it. Not a great problem, just hold the trunk release button on the keyfob for several seconds and this will release the catch and you can pull it open.

 

Especially useful as my de-icer spray was in the trunk!

Keep in mind, de-iced spray is mostly alcohol and will wash out lubricants

Have had similar with rear passenger door frozen up and as the car warms up because I have tried to open the door as the car warms up the door pops on the latch and I have to stop and close it properly.

We have damp conditions which turn into a freeze up and the door seals freeze to the car if they are dry so I have used silicone applied with a cloth to them and it eases this problem.

-6C is fairly common at this time of year. Bloody snow this morning.

Thank you for the non-silicone suggestion.   I will give that a shot.

Unfortunately, I tried the keyfob suggestion, but the catch would not open (must be frozen as well).  And, attempting to get spray lube in there is tough without the trunk opened up.

 

I am thinking to take it to the dealer and have them see about opening things up to dry, then seal any potential seams that might be allowing the moisture infiltration.

 

Any additional thoughts/suggestions are greatly appreciated!  {and thank you to those who replied already}

You do have to hold it quite a long time.

You aren’t alone. Mine does the same thing, and still did it in cooler weather after the dealer “lubricated” the mechanism. I think ultimately the design is flawed to the extent that it will happen no matter what is done to try to prevent it. Maybe an internal spring to the latch mechanism could be stronger to open the clasp with more force or something to that affect. Frustrating no doubt!

Back again, had this this morning, car heavily frosted and unable to open the boot. No sound of the lock operating either from the catch on boot nor using the keyfob.  It freed up later on in the morning, then had a problem the rest of the day.

 

Every time I drove off after getting in I'd had an intermittent alarm as the boot was on the second catch, and flapping a little as I pulled away. I'd have to stop, get out open it and close again, double check it was firmly closed, then it would be OK until the next time I locked and unlocked it! Almost like the release catch was operating by itself.

 

Seemed OK this evening fingers crossed.
