Which Cabriolet are you looking at?

Each Cabriolet generation has its own weak spots. Here are the known problems.

  1. Flexible brake hose deterioration and failure

    Safety risk MC01

    The flexible brake hoses on Smart Cabrios deteriorate at an exceptionally high rate, failing MOT tests at 90 times the national average at some mileage bands. The hoses are subject to extreme flexing due to the car's short wheelbase and stiff suspension setup, causing internal braiding to fail and outer rubber to crack. This is compounded by the exposed mounting points that allow road salt and debris to accelerate corrosion. Hose failure can result in complete brake system pressure loss.

    What to check: Inspect all four flexible brake hoses where they connect the rigid brake lines to the brake calipers. Look for cracking, bulging, or weeping brake fluid around the crimped end fittings. Check for chafing where hoses contact suspension components during steering lock or suspension travel. Gently s...

  2. Brake pipe corrosion

    Safety risk MC01

    Brake pipes on Smart Cabrios corrode at 6.6 times the national average due to their exposed routing and the car's low ground clearance. The pipes run along the vehicle's underside with minimal protection from road salt, water, and debris. The compact design means brake pipes are routed close to heat sources and moving suspension components, accelerating corrosion. Pipe failure results in brake fluid loss and potential brake system failure.

    What to check: Inspect the brake pipe routing along the vehicle's underside, looking for rust, pitting, or white corrosion deposits on the steel lines. Check pipe connections at the brake fluid reservoir, ABS unit, and where pipes meet flexible hoses for corrosion or fluid weepage. Look for brake fluid staining...

  3. Engine mounting bracket failure

    Wear item MC01

    The engine mounting brackets on Smart Cabrios fail at 53 times the national average due to the combination of a rear-mounted engine, convertible body flex, and undersized mounting components. The 3-cylinder engine's inherent vibration, amplified by the lack of structural roof support in the convertible, causes accelerated fatigue in the rubber mounts and their metal brackets. Failure results in excessive engine movement that can damage surrounding components.

    What to check: Open the rear engine cover and visually inspect the visible engine mount brackets for cracks, distortion, or separation from the rubber mount elements. Check for oil contamination on the rubber mounts, which accelerates deterioration. Look for impact damage to nearby components that might indicat...

  4. Brake binding issues

    Safety and MOT risk MC01

    Smart Cabrios show brake binding at 6.9 times the national average due to caliper piston corrosion and contaminated brake fluid. The exposed brake components and minimal ground clearance allow road salt and moisture to accelerate corrosion of the brake caliper pistons and guide pins. This causes brakes to partially engage even when the pedal is released, creating heat buildup and premature wear.

    What to check: Check each wheel for signs of brake dust buildup that appears excessive compared to the others, indicating one brake is working harder. Feel each brake disc after the car has been parked - a warm disc when others are cool suggests that brake is binding. Look for brake fluid contamination in the r...

  5. Shock absorber bush wear

    Wear item MC01

    Shock absorber bushes wear at 8.4 times the national average on Smart Cabrios due to the firm suspension setup and lack of structural rigidity in the convertible body. The constant flexing of the chassis places additional stress on suspension mounting points, causing premature wear of the rubber bushes that locate the shock absorbers. This affects ride quality and handling precision.

    What to check: Inspect the top mounts of both front shock absorbers in the engine compartment for cracking, perishing, or separation of the rubber elements. Check the rear shock absorber mountings accessible from inside the rear compartment for similar deterioration. Look for corrosion on the metal components o...
