Mercedes-Benz GLK-Class Change Vehicle

"DPF failed. Was under warranty, but out of pocket would have been more than $3,000."

"The GLK-250 is a diesel engine and uses Urea (ADBLUE) injection to reduce nitrogen dioxide - either a sensor or an issue with the EGR caused the system to inject too much Urea into the system. This resulted in a noticeable smell of urea from the tailpipe of the vehicle. According to the maintenance manager at the MERCEDES-BENZ Dealer - this could result, over time, in causing the catalytic converter to fail. It required a replacement of the EGR and the sensors connected with the urea process. Luckily the vehicle was still under warranty. It took about 3 months for the dealer to get the parts in and schedule the repair. It seemed to be a common occurrence with the year model and there was a demand for the replacement of the parts. The vehicle did not stop or run rough while we waited for the part. The dealer promised to replace the catalytic converter if there was any demonstrable damage to it while we waited for the part."

"The diesel scrubber sensor has had consistent problems since purchase."

"Engine light came on and nitrous oxide sensor had to be replaced"

"sensor re: exhaust"

"Soot buildup in exhaust system"

"Diesel emissions control modules in the exhaust system failed."

"sensor issue, not sure what but had 3 or 4 of these since bought car in 2015"

"Frequent replacement of NOS sensors."

"The NOx sensors were sending erroneous indications to the computer, threatening to shut the vehicle down."

"Diesel soot sensor failed. Under warranty, but out of pocket cost would have been quite high. This is the second major emissions system failure in 12 months."

"Issue with the sensor detecting the amount of Ammonia available for the diesel engine"

"Sensor went off. We had to take the car in to be checked. It was a momentary blip (the mechanics said) but the light stays on until investigated"

"Within last year, have had to have four Nox sensors replaced"

"Soot buildup"

"nitrous oxide sensor failed"

"It's a bigger issue than MB will admit"

"The electronic system of the parking break was faulted"

"The previous owner must have used the brakes excessively because we have seen no problems after the replacement"

"The brake pads needed to be replaced after 51000km. In the process the rotors were replaced as well"

"Brakes replaced 3 times"

"braking from freeway speeds caused the out of round rotors to vibrate the steering wheel and vehicle. they needed to be replaced - which is very annoying because they wouldn't turn the rotors - they insisted on replacing the entire set up"

"Dealer didnt cover the repair when this happened when its still under 5yrs"

"decelerating from freeway speeds caused front wheel vibration. The rotors and break pads were replaced which corrected the problem"

"braking from freeway speeds caused the out of round rotors to vibrate the steering wheel and vehicle. they needed to be replaced - which is very annoying because they wouldn't turn the rotors - they insisted on replacing the entire set up"

"The two front rotors needed replacement because of excessive wear and the pulsation problems. The used car dealer where we purchased the car replaced all four rotors and pads for the cost of the parts which was just under $300. I am still amazed about this because the Mercedes dealership quoted over $2000 for the front rotors alone"

"they needed to be replaced prematurely"

"Noisy brakes"

"Right rear strut was causing a rattling sound. It was replaced under warranty."

"Strut noise replaced under extended warranty"

"Entire driver side A-frame assembly was replaced due to a severe crack in the metal. It took almost a year of service calls before they finally identified and repaired it."
