2015 Mercedes-Benz GLK 4dr SUV
302-horsepower 3.5L V6 7-speed shiftable automatic RWD
| 55000 mi US $761 |
Stutter while accelerating when cold. Also had inspection after recent purchase. Engine oil leaks, suggested new plugs. Oil leaks were "on the top, front of engine", not fixed, but that was fine with me. I plan to replace the spark plugs so I would have to disassemble the complicated air cleaner and I can see if it was from someone overfilling and dripping oil or actual leaks. If leaks I am a DIY guy. Cold stutter is still there, but it seems to be less and less. Since they recommend plugs at 60k, I am hoping that changing the plugs will correct the problem. |
| 56000 mi US $65 |
At 60k, MB suggests a new serpentine belt. Since this is a new to me car and I was doing other things, I decided to replace the serpentine belt. I ordered an AC, but it was too long so I reordered a genuine MB belt from Amazon and it fit perfectly (at twice the price). |
