The Mercedes-Benz GLK is a luxury crossover SUV that has been produced by the German automotive giant since it was first introduced in 2008. Influenced by the MB C Class W204, the GLK is a popular model in North American markets. However, some problems do arise that owners can find perplexing.
One such issue that drivers have complained about with the GLK is a leaky windshield fluid tank. This problem has been reported to occur on vehicles with under 45,000 miles. That is generally too soon for problems such as this, but it does happen, unfortunately. While this issue may be a small one and relatively easy to fix, it is still a hassle on cars that are relatively new.
One possible culprit in the leak is the rubber grommet that seals the fluid pump. It is simply wearing out too soon. It has been noted by long-time Benz owners that this problem did not seem to occur on previous models and therefore they conclude that a cheaper, less reliable part was used on their cars. If there is another issue with the windshield fluid tank, besides a faulty grommet that leaks, a professional mechanic will be able to determine the cause.
Frustrating yes, but replacement of this part should be relatively inexpensive. To get an estimate of this repair cost and to confirm that this is in fact what is causing the windshield fluid to leak from the tank in the first place, you should take your GLK into an authorized German import technician for an evaluation.
