The 2018 Mercedes-Benz CLA-Class is a compact four-door coupe, embodying sleek styling and a sporty driving experience. Introduced as a gateway to the Mercedes-Benz brand, the CLA offered an affordable entry point into luxury. Key trims included the CLA 250 and the high-performance AMG CLA 45. The original MSRP ranged from approximately $33,000 to $56,000 depending on the trim and options. Its distinctive coupe-like silhouette and premium features made it a popular choice for style-conscious buyers.
The Good

The 2018 CLA-Class boasts a striking design and engaging performance, particularly in AMG guise, appealing to emotional buyers. Practically, it offers decent fuel efficiency and a luxurious interior.

What Problems Does the 2018 Mercedes-Benz CLA-Class Have?

The 2018 Mercedes-Benz CLA-Class has faced some reliability concerns. Frequently reported problems include issues with the electrical system, such as sensor malfunctions, specifically related to the driver-assistance features like blind-spot monitoring and lane-keeping assist. Some owners have reported issues with the infotainment system, including freezing and connectivity problems. There have been recalls related to fuel pump failures and potential issues with the occupant classification system (OCS) that can affect airbag deployment. Long-term reliability can be a concern, particularly with the complex electronic systems. Premature wear of brake components has also been noted. Some model years have had issues with oil leaks, potentially stemming from the turbocharger or valve cover gasket. It's advisable to review the vehicle's maintenance history and conduct a thorough pre-purchase inspection by a qualified mechanic, especially focusing on these known problem areas. Checking for any outstanding recalls or Technical Service Bulletins (TSBs) is also crucial before buying a used 2018 CLA-Class.

How long will the 2018 Mercedes-Benz CLA-Class last?

With proper maintenance, a 2018 Mercedes-Benz CLA-Class can reasonably be expected to reach 150,000 to 200,000 miles, or approximately 10-13 years of service. Key to longevity is adhering to the scheduled maintenance, particularly oil changes, transmission servicing, and coolant flushes. The turbocharger is a potential long-term weakness, as is the electronic control unit (ECU). Suspension components and bushings may require replacement over time. Regular inspections can help identify and address potential issues before they escalate, thereby extending the vehicle's lifespan. Ignoring maintenance can drastically reduce the car's lifespan and increase repair costs.

What Technology & Safety Features are Included?

The 2018 Mercedes-Benz CLA-Class comes standard with a 7-inch infotainment display, Bluetooth connectivity, a rearview camera, and automatic emergency braking. Entertainment features include standard audio system with USB input and HD Radio. Driver-assistance features like blind-spot monitoring, lane-keeping assist, and adaptive cruise control were available as optional extras. Optional features include an 8-inch infotainment display, Apple CarPlay and Android Auto integration, a Harman Kardon sound system, panoramic sunroof, and parking sensors. Safety features include anti-lock brakes, stability control, and a suite of airbags. The 2018 CLA-Class received favorable crash-test ratings from the Insurance Institute for Highway Safety (IIHS) and the National Highway Traffic Safety Administration (NHTSA). The infotainment system utilizes Mercedes-Benz's COMAND interface, which can be controlled via a rotary knob and touchpad. While functional, it can feel dated compared to newer systems. The availability of Apple CarPlay and Android Auto helps to mitigate this, offering a more user-friendly smartphone integration. Overall, the 2018 CLA-Class offers a respectable array of technology and safety features for its class and model year, but some features were only available as optional add-ons.

2018 Mercedes-Benz CLA-Class Prices and Market Value

The 2018 Mercedes-Benz CLA-Class had a starting MSRP of around $33,000 for the CLA 250, while the AMG CLA 45 started around $50,000. As of late 2023/early 2024, used market prices typically range from $20,000 to $35,000, depending on condition, mileage, and trim. The CLA-Class experiences average to slightly above-average depreciation for a luxury vehicle. Factors affecting resale value include mileage, condition, service history, and the presence of desirable options like the Premium Package or Driver Assistance Package. AMG models generally retain more of their value than the base CLA 250. Color also impacts resale value; neutral colors like black, white, and silver tend to be more popular.

2018 Mercedes-Benz CLA-Class Cost of Ownership

The 2018 Mercedes-Benz CLA-Class is generally considered moderately costly to own. Insurance premiums are higher than average due to its luxury brand and potential repair costs. Fuel costs are reasonable, particularly with the CLA 250. However, maintenance and repair costs can be expensive, especially if servicing is done at a Mercedes-Benz dealership. Regular maintenance is crucial to prevent larger, more expensive repairs down the line. While the CLA 250 is more economical, the AMG CLA 45 will incur higher fuel and maintenance expenses due to its performance-oriented components. Budget accordingly for potential unexpected repairs.

2018 Mercedes-Benz CLA-Class Insurance

Insurance for a 2018 Mercedes-Benz CLA-Class is moderately priced, reflecting its status as a Sedan with strong safety ratings and
reasonable repair costs.

How Does the 2018 Mercedes-Benz CLA-Class Compare to Other Sedan?

The 2018 Mercedes-Benz CLA-Class competes with vehicles like the Audi A3, BMW 2 Series Gran Coupe (though the 2 Series Gran Coupe is newer), and Acura ILX. In terms of performance, the AMG CLA 45 outshines most rivals, but the base CLA 250 offers similar performance to the A3 and ILX. Features are comparable, although the Audi A3 may offer a slightly more intuitive infotainment system. Reliability is where the CLA-Class lags behind some competitors; the A3 and ILX tend to be more reliable. Price-wise, the CLA-Class is generally positioned similarly to the A3 and slightly above the ILX when new. Alternatives to consider include the Audi A3 for its better reliability and refined interior, the BMW 2 Series (coupe or gran coupe) for a more engaging driving experience, or the Acura ILX for its value and reliability. If performance is a top priority, the AMG CLA 45 stands out, but for overall value and reliability, the Audi A3 or Acura ILX might be better choices. The Lexus IS (while slightly larger) could also be considered for its reliability and luxury.

Final Verdict: Is the 2018 Mercedes-Benz CLA-Class a Good Sedan?

The 2018 Mercedes-Benz CLA-Class is ideal for style-conscious buyers who prioritize design and brand image over ultimate practicality and reliability. It's a worthwhile purchase if you can find a well-maintained used model with a comprehensive service history. The AMG CLA 45 is tempting for performance enthusiasts, but be prepared for higher running costs. A CLA 250 with optional features offers a good balance of luxury and affordability. However, if reliability is a primary concern, exploring alternatives like the Audi A3 or Acura ILX might be prudent. Thorough inspection and consideration of potential repair costs are essential before making a purchase.
