2022 Mercedes-Benz C-Class Reliability Score & Common Problems

Owners report several recurring issues with the 2022 Mercedes-Benz C-Class power train. Complaints frequently mention acceleration problems, including failure to accelerate and unintended deceleration, sometimes accompanied by engine stalling or misfires. These issues often occur with vehicle mileage ranging from approximately 20,000 to over 50,000 miles. Multiple owners describe instances where the vehicle shifts to neutral unexpectedly or the gear shifter seizes, leading to a loss of control. Two complaints involve crashes, highlighting safety concerns related to sudden power loss and the inability to accelerate or brake effectively. These patterns suggest potential reliability issues that buyers should consider when evaluating this model.

Owners of the 2022 Mercedes-Benz C-Class frequently report issues related to engine misfires, often accompanied by a loss of power or stalling. Common symptoms include the check engine light illuminating, the vehicle entering limp mode, and the need to pull over and restart the vehicle to regain functionality. Complaints often mention these problems occurring around 10,000 to 80,000 miles, with some owners noting recurring issues shortly after warranty expiration. Safety implications are notable, with reports of unintended deceleration and stalling in traffic, leading to hazardous situations. Potential buyers should be aware of these patterns and consider the possible need for significant engine repairs, such as cylinder head replacements.

Owners report frequent issues with the forward collision avoidance system in the 2022 Mercedes-Benz C-Class, particularly with unexpected activation of the emergency braking system. Complaints commonly describe the vehicle abruptly stopping without any obstruction, which can nearly result in rear-end collisions. These issues are noted at various mileages, with some occurring as early as 200 miles. One crash is reported due to the failure of the Active Brake Assist during a frontal impact. Additionally, some owners experience problems with the adaptive speed control and lane-keeping features, which can malfunction or operate inconsistently. These patterns suggest potential safety implications for drivers and others on the road, highlighting the importance of thorough inspection before purchase.

Owners report frequent issues with tire wear and blowouts on the 2022 Mercedes-Benz C-Class, particularly with Bridgestone, Yokohama, and Pirelli tires. Complaints frequently mention premature tread wear and sidewall bubbles, with some noting dry cracking and separation after limited mileage, often under 4,000 miles. Multiple owners describe incidents of tire blowouts after hitting potholes, leading to rim damage and, in some cases, injuries. The issues often emerge within the first 6 to 12 months of ownership, with some owners experiencing repeated failures and high replacement costs. These problems suggest potential safety implications, including loss of vehicle control, which could be a critical consideration for prospective buyers.

Owners report several issues with the service brakes on the 2022 Mercedes-Benz C-Class. Common problems include sudden brake failures, with some noting a spongy pedal feel followed by total loss of braking capability, often shortly after servicing. Complaints frequently mention the automatic braking system activating unexpectedly, causing abrupt stops without obstacles present, which has led to near-collisions. Additionally, some owners describe brakes seizing after exposure to moisture, requiring excessive force to release. These issues are reported across a range of mileages, from less than 100 miles to over 23,000 miles. Notably, one incident resulted in a crash with minor injuries, highlighting potential safety concerns for prospective buyers.

Owners report several issues with the vehicle speed control in the 2022 Mercedes-Benz C-Class. Complaints frequently mention unintended acceleration, with some vehicles accelerating suddenly when using cruise control or during normal driving situations. There are also reports of vehicles failing to accelerate properly, limiting speeds to 20-25 mph even with the accelerator fully pressed. Some owners note incorrect speed limit readings causing abrupt speed changes, which may lead to potential rear-end collisions. These issues are reported across various mileage ranges, and one incident involving unintended acceleration resulted in a crash with an injury. Potential buyers should be aware of these recurring issues that could impact driving safety.

Owners report that the 2022 Mercedes-Benz C-Class experiences airbag non-deployment during crashes, with all three complaints involving collisions where airbags did not deploy. Typical symptoms include severe impact without airbag activation, leading to injuries such as concussions, neck, shoulder, and leg injuries, and numbness. These incidents occur at low mileage, ranging from 200 to 1,192 miles. The safety implications are significant, as all complaints involve crashes resulting in injuries. Buyers should be aware of these patterns when considering purchasing this model.
