Just bought this car and all seems great. My credit union offers great rates on some decent extended warranties however the GLK series apparently is only offered the lowest level of coverage due to number of claims. So basically drivetrain plus coverage (Engine, Transmission, drivetrain including 2 and 4 wheel drive and 50% off parts/labor for cooling and electrical (alternator, starter and voltage regulator only).

Are the items that typically go wrong with this model everything but what this warranty covers? There is no deductible with this coverage which is because it is through the credit union. The price is $1608 for 36 months/85 miles. So the pricing is good and if the issues this model has for the most part (excluding basic maintenance) fall into this low level coverage then I am good. If typically everything that goes wroing with this car is everything this policy does not cover then I would not want to waste $1600.

Any help would be greatly appreciated.

Engine wise, the M276 engine is pretty much bulletproof. The 4matic system is very reliable and so is the transmission. There aren’t too many issues with engine and transmission on the 2013 and onwards GLK models.

With that said, the problems you may face down the road are pretty much all electrical and very common. Here are some of the common problems

1. blind spot assistance radars corroding and failing (very common). Will require new radar sensors and wiring harness - $2000+ to fix.

2. Power adjustable steering seizes in one position. $500+ to fix

3. Requires a new battery every 3 years or so due to the design nature of the electrical system. $200+

4. Requires a new auxiliary battery every 3 years or so for the start stop function and lane keep assist. $150

5. Manual emergency brake seizes in cold weather $200 to fix

6. Camshaft plug leak $100 to fix

7. Warped front rotors (very very common) $750+ to fix

8. Upper windshield weather stripping failure $30 to fix. You can DIY this with some epoxy to keep it in place.

9. Not going into gear (may need new brake switch) $200

10. Rear struts can become noisy and rattle. $1500

11. AC condenser gurgle sounds. May be due to clogged drain hose or low refrigerant.

There’s a reason why third party warranty doesn’t cover electrical components. The warranty provider will go bankrupt in under a minute. However, that’s not to say that your car may never have a mechanical breakdown. It’s just unlikely to happen. If it does happen, the warranty would have paid for itself tenfold. At the end of the day, it’s up to you. Maybe $1600 can provide you peace of mind and better sleep at night.

Extended warranties on any Mercedes are expensive. We bought our 2013 GLK350 used and opted for no extended coverage because it was so expensive. So far so good at 86k miles. My wife loves it. We did just get it out of the shop for $4k worth of hail damage but I only had to pay the $1k deductible. I would save your money for basic maintenance costs. Oil changes, transmission service, coolant changes etc.

a spring in the parking brake assembly needs to be replaced. The whole linkage needs to be lubricated and tightened as well. About $100 for parts and labour.
