2017 Mercedes-Benz C-Class UNKNOWN OR OTHER

Sunroof Front Trim for Mercedes-Benz GLC300 IS ALL SCRATCHED BUT MERCEDES BENZ SAYS IT IS NOT COVERED BY THEM.

My car caught on fire due to AC malfunction

Error code P052E71 on a 2017 c300 with 100k miles. It seems to be a very common and recurring issue that appears to have no real solution and is costing consumers thousands upon thousands. This malfunction does relate to emissions and this vehicle is operated in California.

The same part that was recalled the Starter Current Limiter has overheated again. The dealership is trying to charge for this same part for diagnostic, parts and labor. The car produces smoke around the battery and melted due to overheating. The battery is new. The car only turns over..then immediately overheats. Just because it was recalled and replaced does NOT mean it is perfect from defaulting again. Please have someone look into this matter.

I purchased my 2017 Mercedes c class coupe in 2020, used. Around 2021, I started hear noise from the sunroof when driving on the highway. I went to get it repaired and they mentioned they needed to tighten the screws. This week, I was closing my sunroof and then I heard a crack. I went to a shop to get it manually closed for now on calis 105 degree heat. I am now learning there has been recalls for Mercedes 2017+ coupes but it’s not stated for my specific car to get it fixed. How do I go about this? I feel the sunroof is faulty and has been faulty.

The glass on the panoramic sunroof exploded/shattered under normal driving conditions. It was raining but not too heavy. It didn’t appear that anything hit the glass and no potholes were hit. It seemed to be due to pressure or temperature which caused the explosion which sounded like a loud gunshot and the glass was in pieces. There were no injuries as the sunroof shade was closed and thus the glass fell on the shade. It has not been inspected by dealership or insurance as closed on Sunday and today due to Labor Day, but yes it is available for inspection upon request. However, as it was raining and I needed to get home, I covered the entire sunroof with Duct Tape.

Factory AMG rims. 3 of the 4 rims have cracked. The last rim cracked with brand new tires. So it is not a tire issue. I find it unbelievable looking online how may others have had this problem with AMG rims. Does not seem acceptable.

Car had 69,300 miles (5 3/4 years old) at time of service on 4/18/2023. The check engine light came on the day before. Dealer performed diagnostic- stated it was the Crank Case Ventilation that needed to be replaced. I was charged $2107.00 $1710.00 for labor, $397.00 for parts. I have owned 2 other mercedes well into the 100,000 mile ranges- no problems similar to this. It seems to just be a C300 issue- my car is a C350e. It has been serviced at the dealer every year and is garaged and well taken care of. I read online that c300 have this issue- and would like to report mine as well.

Check engine light code " P052E71" Crankcase Ventilation Valve Replacement is needed. There is a defective part oil separator and the valve is stuck. Must replace the whole assembly with the hoses. (Part is available for inspection). The problem has been confirmed by the Mercedes dealership. When starting the car, gas fumes come out and is very distinct in the air which is VERY dangerous in confined spaces as well as around other people. . You will fail emissions testing due to this. The repair will cost between $1600 - $2000. This is a know defect in these cars and should be recalled. It also pollutes the air and put the safety of everyone around in danger.

at approximately 48,000 miles driven the check engine light turned on when car was taken to the mechanic, code p052e71 came back as the problem, which means crankcase breather hose had to be replaced. the cost was almost 2000 dollars.

On May 3, 2023 I experienced an issue in which the sunroof on my 2017 C300 cert pre-owned with 51,000 miles Benz imploded out of nowhere while driving. My dad who I was taking to the doctors was also in the car resulting in both of us having fragments of glass on us. The problem has been reported to the insurance company and dealer the same day. There were no issues with the sunroof before the event happened.

I’m unsure but my check engine light came on showing something about my pvc valve needing replacement while I was driving

Crank case ventilation valve causing check engine lamp. Car has 42k miles. Recommended repair cost $2000

Engine bay gets too much water whenever car wash has been done due to space between windshield and plastic engine bay shield (right hand side from vehicle driver seat) has slight gap.

There is an existing recall (21V197000) from Mercedes regarding defective glue attaching the roof panel to the car. The roof panel can dislodge and fly off the car, creating a road hazard. I have the same issue on my 2017 C300 where the panel has moved, causing a whistling noise. The deal has diagnosed this issue. However, my VIN is not covered by the Mercedes recall. I have reached out to Mercedes, and they refuse to include my vehicle in the recall. Other 2017 C300 models are included. I believe their recall does not cover all affected vehicles. The recall number is 21V197000.

I’m trying to ship my car back to the United States and there is a valid recall on my car which I have taken it to the dealership in Korea, which is where I’m currently at, and I cannot get me car updated either because they don’t understand the paper or because I don’t have an official recall which I have also encountered in the states. Without this update my car will not be shipped back home with me. Is there any way I can get this recall information in Korean to possibly make them perform the update.

On August 18th, 2021 the roof panel between the windshield and the panoramic roof completely detached while driving on the highway. Luckily no accidents or injuries are reported. Safety recall for this issue has been issued since March 2021 but the factory hasn't produced the parts to send to the dealerships to make the necessary repair to this day. The car is currently unusable and unsafe to drive. Even if the dealership attempts to re-attach another panel they won't have the right adhesive, instructions, and panels that the engineers in the Mercedes factory redesigned to remedy this issue.

IN LATE OCTOBER 2019, I WAS DRIVING ON THE FREEWAY AT 70 MPH. MY PANORAMIC SUNROOF SUDDENLY BLOW UP WITH A LOUD SOUND. MERCEDES CLAIMED THAT A ROCK OR SOMEONE SHOT BBGUN AT MY CAR. HOWEVER, I READ FROM MULTIPLE SOURCES THAT THIS HAPPEN OFTEN WITH THE MERCEDES'S PANORAMIC ROOF. LUCKY FOR ME, MY FAMILY WAS NOT IN THE CAR AT THE TIME.

I HAD AN INJURY IN THE MILITARY AND IT LEFT ME WITH SOME FORM OF TBI. THE CHEMICALS IN THE CAR FROM THE TIME OF PURCHASE TO THE TIME OF SELL LEFT ME WITH A LARGE AMOUNT OF AMNESIA AND AT TIMES PAIN THROUGHOUT THE BODY, ITS NOT SOMETHING THAT'S EASILY REMEDIED. THE TIMES FROM THE CHEMICALS IN THE VEHICLE ALWAYS CAUSED A PROBLEM. I DON'T KNOW WHAT ELSE TO DO.
