Road Test

Furthering its model name revitalization, Mercedes-Benz replaced the sharp-edged GLK compact SUV with a softer-shaped, more refined GLC. The GLC slots between the entry-level GLA and mid-sized GLE.

With bones coming from the excellent C-Class sedan, the GLC swaddles its occupants in a luxurious leather-lined cabin, quiet solitude, and the solid, substantial and sophisticated driving experience typical of Mercedes that convinces people to part with a considerable chunk of change.

What Owners Say

Parking brake

"Electronic parking brake gave inoperable error message"

Anonymous, VA (2018 Mercedes-Benz GLC GLC300 2.0-L 4 Cyl turbo)
Premature brake wear

"Rear brakes worn out in only 20,000 miles. I do not drive aggressively. I've never replaced brakes this quickly, and probably would not have purchased this vehicle if I'd known of this issue."

Anonymous, ID (2018 Mercedes-Benz GLC GLC43 AMG 3.0-L V6 turbo)
Squeaking

"When car was parked in cold garage, loud rhythmic squealing would occur during first several miles of operation. Dealer indicated this was likely due to worn rear brakes, even though the sound occurred when the brakes were NOT being applied. I don't drive aggressively, and yet my rear brakes only lasted 20,000 miles?? Brake wear sensor had not yet activated, but forced to replace rear brakes (at considerable expense) to solve the squeal problem."

"Alarm inside car that is to warn me that another car is close to me goes off even when there are no cars around me"

Anonymous, (2018 Mercedes-Benz GLC GLC300 2.0-L 4 Cyl hybrid)
Tire pressure monitor

"Quite disturbing sensor malfunction. showed low pressure on front tires. Several times pumped and checked the pressure at the gas satiation, only to have the sensor show warning of very low pressure. The dealer said you need to reset the sensor. But it was not clear why in the first place these shall go off and show low pressure when all is really good. I believe this is a bad sensor or manufacturing issue, how ever the dealer was not that keen to correct anyways. The serious issue is that you really do not know whether something is wrong or not. Do we need to get out of the freeways and check tire pressure or not? As far as we are concern this is a real serious issue that has not been resolved after three times discussion with the dealer. Engine noise, the malfunction of the controls of the front seat and the very serious issue with the gas intake for a new care from MBZ is really disturbing. Let me explain more for the last issue. At the gas station when we put the pump nozzle into the car gas intake t simply does not mount, or mounts very rarely so the gas pump trips and does not allow filling the gas tank. I have to keep it low flow, or take the nozzle out several times and put back in to get some gas in. In my 50 years of owning cars I have never seen an issue like this. We told the dealer and they simple said you need to get the hang of it. This is ridicules gassing the car is a major pain in the neck for the GLC300. I think there is something fundamentally wrong with the design or the mount area which does not get the standard gas pump nozzle controlling the flow and tripping only when the tank is full. Is this a recall issue?"

Behnam-Jinus B., CA (2018 Mercedes-Benz GLC)

Kerry M., MO (2018 Mercedes-Benz GLC GLC300 2.0-L 4 Cyl turbo)

"I had an annoying rattle in the front of the center console area. It was intermittent and the dealer did fix it. However the rattle still occurs from time to time. It's not real bad but I expect better from a Mercedes."

Anonymous, CA (2018 Mercedes-Benz GLC GLC43 AMG 3.0-L V6 turbo)

"Significant rattle from driver's side window (when fully closed). Haven't yet taken to dealer for repair (under warranty). Hopefully an easy fix, but shouldn't be an issue to begin with."

Heater system

"When heat is set to a warm temp like 70 degrees, cold air still blows out. I Have to keep it set to about 78 to stay warm in winter. When I press the defrost button hot air blows out. The heating system is not as accurate as any of the other cars we've owned and that's quite a few."

What Owners Say

Glass defects

"The windshield had a glass defect that would not allow the wipers to glide over the window. At one point the blades came undone and the arm scratched the windshield. The system was not usable in the rain. I drove home slowly and waited for a clear day to take it to the shop. They replaced the glass but it did not fully resolve the problem. In fact, today there are still wiper problems and I am afraid that they will become serious again when I am driving but MERCEDES-BENZ refuses to take any further action."

What Owners Say

Sensors (includes O2 or oxygen sensor)

"It turned out to be a serious problem. My car was in the shop for 10 days. I am not sure I even understand everything but somehow they also needed to do substantial work to remove or repair the hybrid battery to deal with the oxygen sensor problem. I frankly don't know if the oxygen sensor problem damaged the hybrid battery or if the placement of the battery and exhaust system made the repair very complicated. The dealer claimed that the extent of the problem was unanticipated the initial estimated time to repair went from 2 days to five days to 10 days."
