2019 Mercedes GLC 300 Transmission Problems
Drivers of the 2019 Mercedes GLC 300 regularly report transmission-related issues, including transmission leaks, rough shifting, slipping, and issues with components such as the gear selector, sensor, or solenoid.
Among the most common transmission issues reported for the 2019 GLC 300 are delayed shifting, where gear changes occur unpredictably and may cause the car to jolt.
Regular maintenance, including checking and replacing transmission fluid, can help address and prevent some of these issues. If you experience any of these problems, you should have your vehicle inspected by a professional.
Transmission services, such as fluid changes and flushes, can be more cost-effective than a full transmission replacement, which may exceed $3,500. A typical transmission flush for the 2019 GLC 300 requires approximately 10 quarts of fluid.
2019 Mercedes GLC 300 Engine Problems
The 2019 Mercedes-Benz GLC 300 has several engine-related issues reported by owners and noted by the NHTSA.
Common problems include sudden loss of power while driving, acceleration issues where the engine hesitates or fails to respond correctly, and frequent activation of the check engine light, often related to problems with the turbocharger or other engine components.
Some drivers have experienced unexpected engine stalling, particularly in traffic, and there have been complaints about oil leaks from the engine that could lead to more severe issues if left unaddressed.
One notable recall affecting the 2019 GLC 300 is identified by NHTSA Campaign Number 21V-961, initiated on December 13, 2021.
This recall addresses a fuel leak that may occur between the fuel rail and injectors, which could increase the risk of a fire if exposed to an ignition source such as hot engine or exhaust components.
2019 Mercedes GLC 300 Braking Problems
Owners of the 2019 Mercedes-Benz GLC 300 have reported several braking issues that can impact both performance and safety.
Common complaints include premature wear of brake pads and rotors, vibrations, pulsations, and noticeable squeaking noises.
For example, some drivers have described loud squeaking sounds occurring specifically when reversing their vehicle.
One of the key issues reported is the appearance of the Anti-lock Braking System (ABS) warning light. This alert can be triggered by various problems, such as a malfunctioning speed sensor, low brake fluid levels, or even complete brake failure.
This warning light indicates immediate attention may be required to ensure safe braking performance.
Premature wear of brake pads and rotors is another common issue in the 2019 GLC 300. When brake pads deteriorate earlier than expected, they can produce a squealing noise that may worsen into a grinding sound if not replaced promptly.
Drivers might also see a “Check Brake Pad Wear” message on the dashboard, signaling that maintenance is needed.
2019 Mercedes GLC 300 Electrical System Problems
The 2019 Mercedes-Benz GLC 300 is prone to various electrical system issues. Some owners have reported problems such as the anti-slip warning activating without cause and the side sensors lighting up despite no nearby vehicles.
According to complaints from the NHTSA, there have been cases of water leakage into the driver’s side footwell, causing electrical components to flood and leading to significant electrical failures.
General electrical failures such as the vehicle not starting, dead key fob batteries, and corrosion on battery terminals have also been noted.
One Mercedes-Benz recall involving serious electrical problems is identified by NHTSA Campaign Number 20V-776, initiated on December 11, 2020.
This recall addresses an issue with the starter power supply cable, which might have been improperly installed.
Such an installation error could cause the cable to short-circuit, leading to vehicle stalling and an increased risk of a crash or vehicle fire.
Another significant recall is identified by NHTSA Campaign Number 22V-365, which was announced on May 20, 2022.
This recall addresses a problem with the emergency call (eCall) system in affected vehicles. An error in the communication module’s SIM card software may result in a failure of the mobile network connection, rendering the eCall system inoperative.
This malfunction could delay emergency response times and increase the risk of injury.
Mercedes-Benz USA announced a recall in February 2024 under NHTSA Campaign Number 24V-070. This recall addresses issues with headlights that may be incorrectly aimed too high, creating excessive glare for oncoming traffic and increasing the risk of a crash.
The recall affects various vehicles, which fail to meet the Federal Motor Vehicle Safety Standard number 108, “Lamps, Reflective Devices, and Associated Equipment.”
As of September 2024, the 2019 Mercedes GLC 300 has been included in at least 5 recalls resulting from electrical system issues.
These electrical problems can be both frustrating and potentially dangerous. If you are experiencing any of these problems, you should have your vehicle inspected by a professional to address the underlying issues.
GLC 300 Consumer Complaints
“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.”
“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.”
“Bought a 2019 brand new. The vehicle currently has less than 20000 miles on it. I have had more problems and it’s been in the repair shop more than any vehicle I’ve ever owned all of them combined, and I’ve owned vehicles for 28+ years. My experience with Mercedes customer care has been horrible!!I have repeatedly asked Mercedes to stand behind their product and they refuse to do so. The vehicle stalled out on a busy street at 10000 miles and had to be towed. I had vehicles flying by me blowing their horns at me because I couldn’t move. Supposedly it was a sensor issue. 2 different times the vehicle would not accelerate. It felt like the transmission was slipping. One of those times I was on an interstate had a vehicle flashing their lights at me to get over and I couldn’t because there was a vehicle beside me. The first time it done that supposedly the transmission fluid was low and it had came that way from the factory???”
Lemon Law Protections for Your Defective Mercedes

The Lemon Law provides legal recourse for consumers whose vehicles consistently fail to meet quality and performance standards despite repeat warranty repair attempts.
This is especially relevant for the GLC 300, which has garnered less favorable reviews and ratings for its reliability, with numerous owners reporting recurring problems.
