POWER TRAIN
My 2018 Mercedes-Benz CLA250 4MATIC is experiencing a knocking noise from the rear differential at low speeds. The issue poses potential driving hazards, including possible loss of control and increased wear on drivetrain components. The noise may indicate a failing differential, which could suddenly fail while driving. I have contacted the dealer, but no specific recalls or factory service announcements have been identified for this problem. This appears to be a common issue reported by other owners. At the recommendation of the service technician, I replaced the rear solenoid, at the cost of $400, but no improvement. A rebuild of the rear differential was the recommendation.

The component that malfunctioned is the Crankcase valve. This valve malfunction has caused issues will the car is idle. The issue has been confirmed by the dealership. The issue has been inspected by the manufacturer as the manufacturer has released extended warranties on other models. The malfunction causes the check engine light to come on, however in the past it has gone off before a diagnostic test could be run; the check engine light would come on and go off then go on and go off, the exact amount of time is unknown.

ENGINE
Although I bought this 2019 Mercedes Benz CLA 250 less than 1 year ago with 18,600 miles on it, in May 2024 the check engine light came on and the dealer service shop gave the following diagnosis: CRANKCASE VENTILATION HOSE. Comments: THE CRANKCASE VENTILATION HOSE HAS AN INTERNAL FAILURE AND IS CAUSING THE CHECK ENGINE LIGHT. THE CRANKCASE VENT HOSE IS NEEDED TO BE REPLACED. Repair Estimate: $1769.00 They told me that it is a known issue and that many other models have been recalled, but because my exact make, year, and model was not yet included I would have to pay out of pocket. This seems wrong since the issue is so prevalent among Mercedes models that there is a national backorder on the part with no definite end. When I reached out to Mercedes about this, they were unwilling to do anything. Please make them add it to the long list of models that have received recalls/extended warranty for this!

The panoramic sunroof on my 2015 Mercedes Benz CLA 250 4Matic spontaneously exploded while I was driving. It was a clear sunny day with no weather and there were no vehicles in front of me that could have kicked up a rock. It sounded like a gunshot, and I scared enough that I veered into another lane. Thankfully I did not hit another vehicle. I had very small superficial cuts on my arm and back. The dealership does not acknowledge any manufacturing defect on the sunroof. After some research I have found there is an open class action lawsuit against Mercedes Benz for this exact issue. The was no warning prior to the issue. There was nothing to inspect as it was just a pile of broken class laying in my car.

FUEL/PROPULSION SYSTEM, ENGINE
Approximately 6 months I noticed my vehicle began to emit an odor and is not responsive immediately when I press on the gas. During this time period a yellow check engine light appeared on my dashboard. My local mechanic recommended Christopher Motors in Warwick Rhode Island and German Motors in Providence, Rhode Island, who specializes in Mercedes. I scheduled an appointment and took the vehicle to Christophers Motors to get a diagnostics check for $130. Christopher motors did a diagnostic check and revealed that the car needs a crank shift ventilator that will cost approximately $1500-$1800 and could not guarantee if the service engine light would be removed. During this time I received a Vehicle Registration Suspension notification for the State of RI for a failed safety inspection. I was extremely stressed receiving this notification as I recently purchased this vehicle, and I am being told by the State of RI my car is unsafe to drive and my transportation for work is being removed. I had to contact the State of RI and advised that no one will fix the safety check engine light problem and I need a time extension to contact the Mercedes Dealer. I then scheduled an appointment with Mercedes, Warwick RI and was told that the part for this repair was back ordered and that there is an extended warranty on this repair. (Exhibit A). This immediately put my mind at ease, and I could see a solution to this two-month long problem. Then I was informed that the extended warranty is only for 14 models all within the same year as my vehicle. The Dealership also advised that Mercedes may add the recall for the CLA 250 in the future and I would be reimbursed for the repair. I then contacted Mercedes of USA by letter requesting that my vehicle experiencing the same design errors on the crankcase ventilation system be included in their extended warranty. Unfortunately they would not add my vehicle to the extended warranty and did not provide a detailed explanation.

VEHICLE SPEED CONTROL, POWER TRAIN, ENGINE
Our car has lost power to accelerate on 4 occasions on the highway. The first instance was in October of 2023, the second instance was in November of 2024 (and was brought immediately to the dealership and they said the fix wasn't available yet), the third instance was in March of 2024 and the most recent incident occurred in June of 2024. For example, the car will be moving at a speed of 60 mph and it will suddenly start flashing lights in the car with a warning signal that the "car is unable to reserve". The car then instantly loses the ability to accelerate and you can push the pedal all the way down and it will not go faster. There is an issue with either the engine, the power train or the speed control, or some combination. The car will not go above 20 miles per hours. These instances have almost caused us to get rear-ended by other vehicles as we suddenly lose the ability to accelerate. It is extremely dangerous and we've been fortunate to be near off-ramps to get off. The problem has been confirmed by Mercedes Dealerships with friends of ours who have experienced the same problem with a different model. They claimed that Mercedes USA had not found a fix yet, but refused to provide us with a loaner car until this death trap of a car was fixed.

roof front panel coating peeling off - there has been a recall for this issue on most mercedes benz of my year - not just my model- seems to consistently be an issue for the front panel between windshield and sunroof- https://static.nhtsa.gov/odi/rcl/2021/RCMN-21V197-6244.pdf my specific VIN wasnt included in the recall but i am having the exact same issue- Mercedes told me to reach out to NHTSA to see about getting my VIN batch included in recall or re-issue broader recall to include my VIN # - they will not replace otherwise - so many people online have same issue as me and obviously it was enough of a hazard that the first recall was issued but there are more cars affected by it than what was covered.
