2016 Mercedes-Benz GLC 300 fuel system complaints
Page 2 of 2: complaints 11 to 21 of 21, newest first, as owners wrote them.
My MB GLC 300 has run out of gas three times. The first two times the car showed it still had 40 miles before fill up and the gas warning light never came on. I took the car in for repair to see if the Fuel level sending unit had stopped working or the float was stuck. The date was March 2020 and at that time the car was under warranty. I was told to make sure I filled up the tank when the fuel indicator reached 100 miles. I was told by the dealer there was nothing wrong and the service department had run a diagnostic. I had never been told that I needed to fill up when a car gauge read 100 miles. Thirty or forty maybe but 100 seemed odd. Two weeks ago I had the gas leak repaired which was the result of the class action law suit. Yesterday I again ran out of gas again. The gas gauge showed 3 bars and 100 miles before next fill up. No gas low warning light came on. I was able to get a friend to bring a gallon of gas so I could drive somewhere to fill up. After I filled the gas tank the gas gauge completely stopped working. The miles to fill up is zero. I have tried resetting the ODM and have checked all the fuses related to the gas tank. This could have been a dangerous situation.
Often after starting the car, inside the car there is a gas smell that we have to closed the vents as it becomes unhealthy until the smell goes away, it last up to 10 minutes. I have taking the car to my mechanic who specializes on Mercedes and could not find any leaks and/or anything wrong. My other issue is that during the raining season when I put my foot on the breaks it makes this loud sound like an airplane landing that I have to release and press and release and press so the car will slow down. My mechanic have done multiple inspections and finds nothing wrong. My third issue is the suspension, driving on freeways at speeds over 55 mph I feel a lot of shaking between front wheels and I can feel every single bump. Again, my mechanic has found nothing wrong that even checked for recalls and has told me that there are no recalls for this vehicle. Obviously there has to be a recall issue and the one more concerning is the gas smell inside the car at start up.
Fuel smell entering cabin after start up, fuel line on drivers side near steering column leaking, googled problem and seems to be common occurrence with glc300, and mercedes c class but no recall, this is the same problem as the mercedes metris has but there was an recall issued for that model
Tl* the contact owns a 2016 mercedes-benz glc300. The contact stated that while the vehicle was in for service at the local dealer mercedes benz of thousand oaks located at 3905 auto mall dr, thousand oaks, ca, the mechanic noticed the odor of fuel coming from the vehicle and diagnosed that the low-pressure fuel line was leaking and needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was 60,000.
Leakage in fuel system ( high pressure pump). On glc 300. Gas small inside the car. Company denied investigating or providing my refund for repair. I feel this is totally safety failure of the vehicle . So my current mileage is 32908 and it is 2016 model. I bought this vehicle because the company claims for its highest standards of safety. So I want the authority to help me in investigating this issue and provide me assurance and coverage for any kind of safety issues in future. Also, I want to report some minor issues on breaks. I see sometime the there is a delay in action. Hope this will be investigated for preventive actions and get my refund for fixing this kind of safety related matters. Its is total responsibility of manufacturer to deliver the safety vehicle. Not to escape by saying warranty clause
When I start my car there is strong gas odor in the cabin for the first 3-4 hours of driving. Also there is a moldy smell in the warmer months as well
I purchased this mercedes new in 2016, the brakes have squealed ever since when cold 32 degrees or less.. Once in awhile when warm. 2 we smelled gasoline, we took it to a repair shop, they found two fuel hoses sprayed gas in a mist especially when cold.. 3 there are 3 recalls open on this mercedes, I took it in when the air bag recall arrived at our house, I was told we don't have parts. Our car is out of warranty, it has 56000 miles. I take it to a repair shop run by certified mercedes technicians. Thank god we didn't have a fire with the gas leak. I did smell the gas when moving thru the ventilation system and when sitting and the smell was all around the car.
Tl* the contact owns a 2016 mercedes-benz glc300. The contact noticed a strong fuel odor inside and outside the vehicle. The failure occurred periodically. The vehicle was taken to zt motors of fort walton beach (1000 n beal pkwy nw, fort walton beach, fl 32547, (850) 863-8372) to be diagnosed, but the cause of the failure could not be determined. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was 10,000.
On cold start (7am, between 60 and 70f degrees), there's a strong gas smell on both the cabin and outside the vehicle. No check engine light is on or any other indicator of a failure. There's no visible leaks on the underhood or my driveway. Really scared to take my kids to school unless mb solve this problem. Vehicle still under warranty, mb dealership shouldn't charge for the inspection. Taking vehicle to el paso tx dealership. Will see what happens.
Three weeks after buying the glc300 4matic the engine misfires, got stranded in AC new jersey, the car was at the dealer for 3 weeks, they replaced all fuel injector/coils and it kept happening, then the fuel module got replaced and it ran fine for 4 weeks and the problem came back, got stranded in boston, the car was at the dealer for 2 weeks, this time they replaced the engine control unit (today 4-22-16), I'm picking it up tomorrow. I own the car for 12 weeks and only been able to drive it 7 weeks, so disappointed in mercedes benz.
