Complaints frequently mention unexpected vehicle shutdowns and dashboard alerts, often occurring around 8,000 to 9,600 miles. Notably, three incidents involve unintended acceleration during low-speed parking maneuvers, resulting in crashes with no prior warning signals or alerts. These issues pose significant safety risks, as they include loss of vehicle control and failure of critical safety systems. Potential buyers should be aware of these reported problems, especially considering the involvement of crashes and persistent electrical malfunctions.
UNKNOWN OR OTHER
6 complaintsOwners of the 2024 Mercedes-Benz C-Class report several issues in the UNKNOWN OR OTHER category, with a notable pattern of the vehicle experiencing unexpected jerking movements. These jerks occur at various speeds and conditions, such as while driving at 70 mph, making turns, or even when stopped, and have been reported to cause discomfort and potential safety concerns. Another issue involves the vehicle unexpectedly shifting from drive to neutral, requiring a restart in the middle of the road, which poses a significant safety risk. Additionally, complaints mention the car failing to start with multiple warnings displayed, though a software update has been attempted to address this. Incidents are reported at mileage ranging from 200 to 9,100 miles. Safety implications include potential loss of vehicle control and the risk of accidents due to sudden vehicle behavior.
SEATS
2 complaintsOwners of the 2024 Mercedes-Benz C-Class frequently report issues with the vehicle's seats, specifically mentioning the driver’s seat moving backward on its own while driving and the passenger seat bouncing and vibrating. The driver’s seat issue has been noted as occurring in various driving situations, including on highways and in parking areas, posing a potential safety risk due to unexpected seat movement. The passenger seat problem is described as persistent, with dealership technicians acknowledging the issue but stating that it affects all vehicles of this model year. These complaints do not specify particular mileage ranges, but the recurring nature of the issues suggests they may be present from early in the vehicle's use. Safety implications include potential loss of control due to the driver’s seat movement.
SERVICE BRAKES (2 complaints)
SERVICE BRAKES
2 complaintsSafety-relatedOwners of the 2024 Mercedes-Benz C-Class report issues with the service brakes, specifically mentioning a malfunction in the brake-by-wire system that leads to unintended acceleration. One owner describes a severe incident where, despite pressing the brake pedal, the vehicle accelerated into a cinder block wall, with skid marks indicating a possible brake imbalance. This incident, which involved a crash, highlights a critical safety concern as it occurred without any prior warning lights or dashboard messages. The vehicle in question has not yet been inspected by the manufacturer or authorities, and the issue has not been reproduced or confirmed, suggesting a potentially isolated or unconfirmed pattern. This information is crucial for potential buyers to consider, especially regarding the vehicle's braking reliability and safety.
POWER TRAIN (2 complaints)
POWER TRAIN
2 complaintsSafety-relatedOwners of the 2024 Mercedes-Benz C-Class report issues primarily related to the powertrain. One complaint describes a post-airbag deployment PCM lockout, which prevents the vehicle from restarting and has led to a crash, highlighting potential safety risks in emergency situations where immediate evacuation is necessary. Another complaint involves harsh, abnormal shifting between 3rd and 4th gear at speeds of 25–35 mph during normal acceleration, with reports of a sudden jerk or hesitation. This shifting issue has been documented by a dealership technician but persists intermittently despite multiple service visits. Buyers should be aware of these potential drivability and safety concerns when considering this vehicle.
SUSPENSION (2 complaints)
SUSPENSION
2 complaintsOwners report issues with the suspension of the 2024 Mercedes-Benz C-Class, specifically noting a creaking noise from the rear, attributed to severe rust on the subframe. One complaint mentions that this problem is recognized by Mercedes, which offers an extended warranty, although a recall has not been issued. Another complaint highlights repeated blowouts and rapid pressure loss in the factory 21-inch AMG wheels with Pirelli tires, confirmed by both dealerships and independent repair shops, occurring over approximately 18 months. The vehicle involved in these incidents had approximately 120,000 miles. These issues may pose safety risks, as the rusted subframe is described as critical to the vehicle's structure, and tire failures have occurred during normal driving.
WHEELS (2 complaints)
WHEELS
2 complaintsOwners report issues with the Pirelli tires on the 2024 Mercedes-Benz C-Class, specifically noting the development of bubbles on the sidewalls and air leakage. Complaints frequently mention that these issues lead to flat tires, with one owner experiencing five flat tires within 40 days. The symptoms typically occur during normal driving conditions, with one instance following a minor impact with a pothole. Safety implications are noted, as one owner describes a near-collision due to sudden tire pressure loss. These reports suggest potential concerns for used car buyers regarding the tire's ability to support the vehicle's weight, particularly those equipped with 21-inch rims.
EXTERIOR LIGHTING (1 complaints)
EXTERIOR LIGHTING
1 complaintThe master central screen as well as the passenger screen that contains all features for radio, navigation, control of reading road signs, climate control and the like go BLACK randomly during the four weeks I have owned the 2024 E Class Mercedes. It will reboot after 2-5 minutes with no lost data. Dealer in Cherry Hill, NJ did major software update not completed at time of purchase. But incident happened after two weeks. Others with this make, year and model have same situations with dealerships not knowing anything. Supposedly, Mercedes knows but a solution may be three months or more. This is a safety issue as if happens at night, you lose all connections even to the cell phone and no speed sign indicator on. You cannot see anything but the driver screen with just the speed you are doing. Cruise control disengages which is using all security systems and navigation map.
STEERING (1 complaints)

C300 Turn signal flashes 3 times then goes out dash says check left turn signal
Every time I start the car, the lights are fine and no messages in dash. As soon as I use the left turn signal, it flashes 3 times then goes out. Dash says check left turn signal. The same thing applies to one of the two front parking lights on each headlight unit (left and right) and and the left side indicator. I can drive all day with no problem but as soon as the automatic headlights come on the parking lights and side maker come on briefly then go out and I get messages for each on dash. Replaced both headlight/turn signal units and the exact same issue persists. Turn it off and it starts all over. Maybe unrelated but when I use rear defroster radio gets static; also volume knob in center dash is inconsistant but the volume buttons on the steering wheel work fine. More than a year

How We Calculate Reliability Scores
Auto Reliability Index scores are calculated on a 0–100 scale using a weighted formula that combines multiple public data sources. Each factor is weighted based on its predictive value for real-world ownership experience.
Key Ranking Factors
Complaint Severity
NHTSA owner complaints weighted by component category (e.g., powertrain, safety systems, electronics, cosmetic) — safety-critical issues carry more weight than cosmetic ones. Adjusted for sales volume so high-volume models aren't unfairly penalized.
Repair Costs
Independent reliability ratings based on repair frequency, average repair costs, and severity of typical repairs for each model.
Recall Impact
Number of NHTSA recalls weighted by severity. “Stop driving” and fire-risk recalls are penalized more heavily than minor software or labeling recalls.
Issue Diversity
Measures how many major vehicle systems (engine, transmission, electrical, braking, etc.) have recorded complaints. A vehicle with issues spread across many systems may indicate systemic quality issues.
Scores are grouped into four tiers:
- 80–100: Excellent — Top-tier reliability, minimal issues
- 60–79: Good — Reliable with some minor concerns
- 40–59: Mixed — Notable issues, research before buying
- 0–39: Risky — Significant problems, proceed with caution
Data is sourced from NHTSA recall records, owner complaint filings, and independent repair databases. Scores are recalculated as new data becomes available. While the weighting model is proprietary, all underlying data sources are public and traceable.
