Dealer reported to me that the brake lines are rusted. Dealer reported the lines are painted rather than coated as they were in the past. Vehicle is less than 10 years old so brake line rusting seems unusual.

Sudden loss of brake function with large amounts of brake fluid leaking from the car.

Vehicle has ~ 20K miles, brought into dealer because ABS light went on while driving saying system was inoperative. Dealer then found gas tank leak, and would not let me leave the dealer, because of the safety hazard. Search shows recall for earlier model year 2012 with same issue, but dealer says no recall for 2013. ABS sensors are also malfunctioning while driving. Two separate incidents for ABS sensors. Two been replaced within one week!

Emergency brake fails to release. If released brake cannot be applied because it freezes. Brake was used regularly when in park as prescribed. Brake was also excersized according to procedures on P.165 of the 2012-3 glk owners manual. Underbody of car was gently washed periodically to flush any salt etc. From exposed brake lines as per manual when car was washed on a regular basis. Now it cannot be applied in emergency situations. There is no visible corrosion on the brake lines. This is a known problem with mbusa 2012 -2015 glks. Result" one E cannot apply the emergency brake in an emergency situation. This is a know problem with C and glk class cars that mbusa refused to recognize. It maybe a problem with the linkage in the firewall. Again this is a safety problem in an emergency. Car is always garaged.
