Which Cla are you looking at?
Each Cla generation has its own weak spots. Pick the one you’re viewing to see what to check.
-
Excessive brake pad wear
Safety and MOT risk C117, C118MOT data shows CLA models fail brake pad thickness tests at up to 15.3 times the national fleet average, particularly on 1.6-litre petrol variants at low mileage. The issue affects all engine variants and appears across all mileage bands from new cars to high-mileage examples. This suggests either undersized brake components for the vehicle weight, aggressive pad compounds, or brake system design issues causing uneven pad wear patterns.
What to check: Check brake fluid level in the reservoir - low fluid often indicates worn pads have pushed caliper pistons out, requiring more fluid volume. Look through wheel spokes at the brake discs for deep scoring, blue heat discoloration, or obvious thickness variation. Check for any brake dust accumulatio...
-
Brake fluid loss
Safety and MOT risk C117, C118MOT data shows CLA models fail brake fluid level tests at up to 11.5 times the national fleet average, particularly affecting 1.3-litre petrol variants in the 40,000-60,000 mile range. This pattern suggests either brake system leaks developing at specific service intervals, brake caliper seal degradation, or brake fluid consumption through normal pad wear being unusually high on this model.
What to check: Check brake fluid level in the reservoir under the bonnet - fluid should be between MIN and MAX marks on the translucent reservoir. Examine the fluid colour - brake fluid should be clear or light amber, not dark brown or black which indicates contamination. Look under the car for brake fluid stai...
-
Suspension joint dust cover deterioration
Wear item C117, C118MOT data shows CLA models fail suspension dust cover tests at up to 7.2 times the national fleet average, particularly affecting 2.1-litre diesel variants from 20,000 miles onwards. The failures span all mileage ranges from 20,000 miles to 150,000+ miles, suggesting either poor-quality rubber compounds in the dust covers or suspension geometry that places unusual stress on the protective boots covering ball joints and bushes.
What to check: With the car parked, crouch beside each wheel and visually inspect the suspension components visible through the wheel spokes. Look for rubber or plastic dust covers (boots) that appear split, torn, or completely missing from ball joints, drop links, and suspension arms. Check for grease leakage ...
-
Engine management light illumination
Electrical C117, C118The pattern affects all mileage bands including new cars, suggesting emissions system faults rather than wear-related issues. Common causes on Mercedes diesels include DPF regeneration problems, NOx sensor failures, and EGR valve carbon build-up.
What to check: Turn the ignition to position 2 (without starting) and observe the dashboard warning lights - the engine management light (amber engine symbol) should illuminate briefly then extinguish. If the light remains on constantly, this indicates a stored fault code requiring diagnostic scan. Ask the sell...
-
Brake disc wear
Safety and MOT risk C117, C118MOT data shows CLA models fail brake disc thickness tests at 3.3 times the national fleet average, with 1.8-litre diesel variants particularly affected at 80,000-100,000 miles. The issue spans all engine variants and mileage bands, correlating with the documented excessive brake pad wear on this model. Accelerated disc wear suggests either inadequate brake disc specifications for vehicle weight or brake system design issues causing excessive heat generation.
What to check: Look through wheel spokes at brake discs for obvious thickness variation, deep scoring, or blue heat discoloration indicating overheating. Check disc edge thickness - worn discs have sharp lips at the outer edge where pad contact has worn the friction surface below original thickness. Look for ru...

Cla questions
Is the Mercedes Benz Cla reliable?
15.6% of Cla models fail their MOT based on 110,412 tests analysed. That’s about average for the class. There are 5 known problems to watch for, the most serious being excessive brake pad wear. A full history check shows whether a specific car has had related write-offs or insurance claims.
What are the main problems with a Mercedes Benz Cla?
The most serious known issues are excessive brake pad wear, brake fluid loss, suspension joint dust cover deterioration. Problems vary by generation, so check which apply to the year you’re looking at. Our car check flags whether a specific Cla has been written off or had insurance claims linked to these faults.
How do I check if a Mercedes Benz Cla has outstanding finance?
Enter the registration on this page. We query Experian’s finance database and return any outstanding agreements within a minute. If finance is still owed, the finance company can legally repossess the car even after you’ve paid the seller. At £7.49 it’s the cheapest way to avoid a car that isn’t legally for sale.
How do I check if a Mercedes Benz Cla has been written off?
Our check queries Experian’s insurance write-off database for Cat A, B, S and N markers. A Cat S or N Cla has been structurally or non-structurally damaged and repaired. This doesn’t mean it’s unsafe, but it affects resale value and some insurers won’t cover it. The check costs £7.49.
Can I check a Mercedes Benz Cla for free?
You can check MOT history free on GOV.UK, which shows past test results and advisories. What it won’t show is outstanding finance, write-offs or theft markers, which are the things that actually cost you money after you’ve bought. Our full check adds all of that for £7.49, using Experian data.
Is a Mercedes Benz Cla HPI check worth it?
HPI is one brand of car check. Our check uses the same Experian data covering finance, stolen, write-off and keeper history, plus MOT analysis and known Cla faults that HPI doesn’t include. At £7.49 it’s typically less than half the price of an HPI check.
What does a Mercedes Benz Cla fail its MOT on?
The most common MOT failure on the Cla is any fracture or welding defect on a wheel. 15.6% of Cla models fail overall, based on 110,412 tests. Checking a car’s full MOT history before buying shows you recurring problems the seller might not mention.
