2019 MERCEDES-BENZ GLC 300 Complaints

P052E PCV valve issue, as for many others, this part malfunctioned about a month after warranty has expired. This seems to be a known issue for this model (GLC300) according to many online forums.

Our 2019 GLC with 25,000 miles flooded from the inside out with no warning -- a terrifying safety concern. One day when driving to work the car felt slightly odd while driving on streets in Washington, DC. Pulled over to the side of the road and car would not start. Dealer sent tech and jumped the car after a few attempts. Dealer/repair thought the car had a bad battery and voltage dip limiter. Repaired both and returned car. The next day the car drove in the morning but would not start again; was towed to dealer. Dealer/repair reported the limiter was "fried"; repaired again but at our insistence investigated further because we suspected a short and wanted to understand why. Upon further investigation the dealer discovered our car was flooded on the driver's side on the inside; electrical components flooded. There was no warning; no indication of water. After subsequent water testing dealer/repair estimate stated that it was a "slow drip of water in the area of the driver footwell, right side. Can feel by hand water around area where heater hoses and A/C lines come through the firewall." We alerted Mercedes and were concerned because there was no warning and because we found other similar recalls: (https://www.motorsafety.org/mercedes-benz-recalls-suvs-for-water-leak/ and https://www.motorsafety.org/mercedes-benz-issues-third-recall-for-water-leak-that-can-lead-to-fire-limp-home-mode%ef%bf%bc/). We believe this is a defect in the car; Mercedes instructed us to file this form if we were concerned about safety and the integrity of the vehicle.

From the beginning, I have had issues with my car and received nothing but patronizing responses from both the dealership and the service department. From the very start, I have experienced constant issues with my car, only to be met with a condescending attitude from all levels of senior staff members at the dealership and the service department. When I asked for solutions, their solution was to inform me that I was merely using my car door handle incorrectly to open it and activate keyless go. The repair department refused to acknowledge any mechanical faults and instead blamed me as the operator although I had no issues with operating any of their loaner vehicles. Mr. Max Spata eventually arranged one last attempt at repair, yet I was immediately denied service after the service department eventually received notice of my legal letter asserting my rights under the contract. Instead of making an attempt to remedy the solution as requested in that letter, the service department called and advised me that they were demanding the return of the loaner vehicle and that I must pick up my vehicle immediately. The service department then subsequently refused to make any attempts to repair the vehicle under warranty and have continuously made me feel as if my issues are invalid. Throughout the entire process, I have felt invalidated and belittled by their attempts to gaslight me in order to avoid responsibility for their faulty product. The vehicle has experienced several malfunctions, including but not limited to, the KeylessvGo Entry malfunctioning while attempting to enter the car, the vehicle locking without beingvprompted, and the vehicle failing to recognize when keys are inside, thus not allowing it to operate. Moreover, there have been several audio/muffled sound issues with the vehicle's radio system, which have significantly impacted my driving experience. Additionally, I have experienced a recurring problem of the vehicle locking the keys inside the car.

The command system keeps turning off and rebooting while driving. Sometime it makes the rear camera don’t work(blackout), auto on/off does not work, it happens about every two minutes making it dangerous.

Hello, I own a 2019 Mercedes Benz GLC 300 that's been on recall with no remedies released since April of this year. The recall is a SIM module defect that is suppose to help the driver get ahold of emergency responders in case an accident were to happen. The remedy is suppose to be OTA, but I have not seen anything update on my vehicle and I am worried Mercedes is going to forget about this update.

While driving on the interstate (65mph) in traffic, there was a sudden loss of power causing deceleration and the inability to maintain speed. A collision was barely avoided both from being rear-ended and from trying to safely move to the shoulder while other traffic passed. A certified mechanic later determined the piston in cylinder 2 broke, the spark plug broke and the piston rings pulled to the top. The mechanic also said, "Replacement of engine required." The vehicle has 52,839 miles (2,839 miles above the 50,000 warranty). There were no warning lamps or messages and no symptoms of the problem prior to the failure. A QUICK INTERNET SEARCH SHOWS THIS IS A COMMON OCCURENCE WITH THESE VEHICLES. WHAT DOES IT TAKE FOR A FORCED RECALL?

-I purchased a GLC300. Today I discovered I own a GLC 230 HAZMAT SUV with a Hydrogen tank and other dangerous items. German hazard lights that do not mirror my driver's manual or the car I purchased. -Hazard lights showing SRS systems malfunctioning - Hazard lights showing projected contact -Two unwanted unknown installations of Mercedesa branded navigation systems have been installed in my car without my permission. This is not over the air updates. I have the serial numbers. Mercedes-Benz has yet to respond to my requests for safety and information.
