2020 Mercedes-Benz E-Class Common Problems by Component
35 owner complaints grouped by vehicle system.
ENGINE
3 complaintsSafety-relatedOwners of the 2020 Mercedes-Benz E-Class report several engine-related issues. One common problem involves the engine shutting down unexpectedly while driving, with no prior warning lights, as described by an owner who experienced multiple stalls on the highway. Another owner reports an engine lock-up following an air conditioning compressor failure, which prevented the vehicle from restarting. A significant safety concern is highlighted by a complaint about a fire originating in the engine compartment while the car was parked and turned off, shortly after servicing, with the vehicle having approximately 18,000 miles. These complaints suggest potential reliability and safety issues that prospective buyers should consider, especially regarding unexpected engine failures and the risk of fire.
BACK OVER PREVENTION
3 complaintsOwners of the 2020 Mercedes-Benz E-Class frequently report issues with the rearview camera system, specifically noting that the camera either becomes inoperative or the image freezes. Some describe the camera image failing to display entirely, with an error message indicating inoperability. This issue is often reported around mileages of 34,000 to 48,000. These failures can impact safety by reducing rear visibility when reversing, though no direct incidents or accidents are mentioned. Buyers should be aware of these potential issues and verify if the vehicle has been serviced or repaired for this problem.
POWER TRAIN
2 complaintsOwners of the 2020 Mercedes-Benz E-Class report issues related to the power train, with specific problems involving the engine electrical harness and the gasoline saving START/STOP feature. Complaints frequently mention corrosion of the engine electrical harness at around 50,000 miles, attributed to oil leaks from the camshaft sensor, leading to potential power loss or engine misfiring. Additionally, the START/STOP feature is reported to fail at traffic signals, causing the vehicle not to restart and resulting in unintended rolling into intersections. These issues arise without warning lights, and one case required software updates for resolution. The reported problems occur around 47,000 to 50,000 miles and have implications for vehicle control and safety, particularly in traffic situations.
UNKNOWN OR OTHER (2 complaints)
UNKNOWN OR OTHER
2 complaintsOwners of the 2020 Mercedes-Benz E-Class report issues related to unexpected engine shutdowns and warning messages. Complaints frequently mention the "Engine Warning" message appearing intermittently, with diagnostic results indicating an inoperative oil pump valve, which could incur repair costs exceeding $5,000. Another commonly reported issue involves dashboard lights dimming followed by the vehicle shutting down without prior warning, even while driving. These problems occur at relatively low mileage and can lead to potentially unsafe situations, such as the vehicle stopping suddenly on the road. Buyers should be aware of these issues when considering a used 2020 E-Class, as they may affect reliability and safety.
ELECTRICAL SYSTEM (2 complaints)
ELECTRICAL SYSTEM
2 complaintsSafety-relatedOwners of the 2020 Mercedes-Benz E-Class report issues primarily with the vehicle's electrical system, including a serious incident involving an engine compartment fire while the car was stationary at a stop light, resulting in total vehicle damage. This incident occurred with a vehicle having less than 15,000 miles, suggesting potential early-life electrical system failures. Another complaint involves the trunk's automatic closing mechanism, which reportedly failed to detect an obstruction and caused an injury when it closed on an owner's head. These complaints highlight significant safety implications, particularly the risk of fire and personal injury from malfunctioning components.
STRUCTURE (2 complaints)
STRUCTURE
2 complaintsOwners of the 2020 Mercedes-Benz E-Class report two main issues related to the vehicle's structure. The first involves the panoramic sunroof unexpectedly exploding, showering the car's interior with glass without any apparent external cause. The second issue concerns defective door hinges, where the doors fail to stay open due to malfunctioning detents, leading to doors closing too quickly and posing a risk of injury. These problems have been noted regardless of external conditions or mileage, with one report indicating an injury from a door slamming shut. These complaints highlight potential safety risks for both the driver and passengers.
TIRES (2 complaints)
TIRES
2 complaintsOwners of the 2020 Mercedes-Benz E-Class report issues with tire failures, specifically involving the sidewall and tread junction. Complaints frequently mention tears and splits in the tire sidewalls, with one owner noting a complete deflation and subsequent shredding of the tire after attempting to drive on it. These issues are typically reported around the 15,000 to 17,000-mile range. While no accidents are reported, one owner describes being stranded without a spare due to the use of run-flat tires, which may pose a risk of being immobilized. Buyers should be aware of potential tire integrity concerns and the limitations of run-flat tires in emergency situations.

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.
