| Description of the problem | My 2014 mercedes glk 250 with 16,705 miles, on 11/03/2015 experienced the engine warning display stating to add blue. I did this but the warning did not remove but stated i had 10 starts remaining. I was 700 miles from home so returned conserving my remaining starts. Found multiple problems with the blue tech emissions system including def injector nozzle failing to spray. All covered by warranty. On 06/15/2019 with 58,129 miles, the engine warning light again came on to add blue. I checked bluetec level to be nearly full. The warning stated i had eight remaining starts. Being 700 miles from home, i returned. Having three remaining starts. I took the vehicle in for immediate repair. Found nox sensor 2 faulty and was replaced. On 6/28/2019 with 58,126 miles, the add blue warning again appeared. The bluedef warning only 10 starts remains. The nearest merecedes dealer was in denver being 173 miles away. I took it there where they replaced def module, the preheater and tank temp amoung other faults. On 7/15/2019, with approx. 58,300 miles, the same warning appeared. Returned to the same denver dealer who then replaced the nox sensors in the emission system. I was informed that the frequency of repair for this model is very high and expensive (my last totaled $5,000). This vehicle is totally unreliable and should have been recalled. Because of the emmision system utilized, numberous other problems occur such as the complete windshield washer system was replaceddue to the extreme heat created by the system. Same with oil leaks, etc.. Mercedes could have at a minimum extended their skimpy warranty of 50,000 miles but they refuse to acknowledge any fault claiming "the best or nothing"! This model is definitely nothing! |
