MERCEDES-BENZ C 300 2024 ELECTRICAL SYSTEM
low
While I am driving my car it will make a loud crackling sound then my screens go black and warning sounds go off! This is not normal and I read there are recalls but when I entered my vin# nothing came up. Not to mention since I bought the car last February, I have had nothing but issues with my AC turning off which that I have taken to the dealership with video proof and told it was a software update which did not fix the issue. i am paying way too much money for a newer vehicle and having more issues than my 2015 Mercedes Cla 250.

DRIVING A 2024 MERCEDES C300 ON THE FLORIDA TURNPIKE IN THE LEFT LANE AT 70 MPH THE ENGINE SUDDENLY SLOWED DOWN. WHILE THE VEHICLE SLOWED IN HEAVY TRAFFIC I WAS ABLE TO MERGE TO THE OUTSIDE LANE WHERE IT STOPPED. I CALLED MERCEDES EMERGENCY WHO SUGGESTED WAITING A WHILE AND TRY STARTING THE VEHICLE .

MERCEDES-BENZ SPRINTER 2500 2024 SEAT BELTS

My vehicle was inspected and it was found that the seatbelt B-pillar anchor bolt was stripped at the factory. This problem seems widespread online.

MERCEDES-BENZ SPRINTER 2500 2024 SEAT BELTS
medium
I removed the drive side seat belt bolt in order to remove the pillar it is mounted to and found the bolt extremely hard to turn and ultimately somewhat stripped upon removal. The bolt remains defiant in re-installation procedure. The passenger side was removed without stripping but did attempt to cross-thread itself upon re-installation which was remedied by simple hand threading. Safety put at risk in that these seat belt bolts and their installation process may not restrain passengers in an accident. Not confirmed by dealer or service center - pictures should be self evident. The component hasn't been inspected by any party - I'm just going to buy a new bolt and re-tap the hole it was installed in. No warning lights for this isssue.

MERCEDES-BENZ SPRINTER 2500 2024 ELECTRICAL SYSTEM
medium
2024 Mercedes-Benz Sprinter 2500 experienced unusually rapid brake, tire, and battery wear at low mileage. Front brakes required replacement at approximately 29,000 miles. Rear brakes were already worn low by approximately 37,000 miles. Rear tires required replacement by approximately 37,000 miles. Vehicle battery also failed and required replacement before approximately 37,000 miles. Vehicle had earlier emissions/sensor related repairs as well. This creates safety concerns because premature brake wear can reduce stopping ability and increase stopping distance. Premature tire wear can reduce traction, especially in rain, and increase risk of tire failure or blowout. Unexpected battery failure can disable the vehicle without warning in traffic or roadside conditions. Vehicle is used in normal commercial delivery service and is generally not heavily loaded. I have owned and operated multiple prior Sprinter vans over many years, and previous model years achieved substantially longer brake, tire, and battery life under similar or heavier use. A newer comparable fleet vehicle with similar mileage has not required these repairs. The issue appears abnormal compared with prior ownership experience and may indicate brake system drag, an alignment issue, defective components, battery charging issue, or another unresolved defect. Vehicle has been serviced by dealer and components were replaced, but premature wear remains the concern. In addition, rear brake wear occurring this early suggests possible imbalance or excessive brake application that should be investigated. Rapid tire wear combined with brake wear may indicate alignment or braking system issues affecting vehicle control and safety. I am submitting this complaint so the condition can be reviewed for potential defect trends affecting other similar vehicles. Defective parts may be available from prior repairs depending on service center retention.
