Which Gl 320 are you looking at?
Each Gl 320 generation has its own weak spots. Here are the known problems.
-
Brake pipe corrosion
Safety risk X164The GL 320 uses steel brake pipes that are vulnerable to corrosion from road salt and moisture. The pipes run along the underside of the vehicle where they are exposed to road spray and debris. MOT data shows this model fails brake pipe corrosion checks at 3.5x the national fleet average, with failures occurring from 80,000 miles onwards. The large, heavy SUV body places high demands on the brake system, making any reduction in hydraulic pressure from corroded lines a significant safety concern.
What to check: Inspect the brake pipes visible along the chassis rails and rear axle area for rust, flaking, or white corrosion deposits. Look particularly at pipe joints and clips where moisture can collect. Check for any signs of brake fluid leakage around pipe connections - fresh fluid appears clear to amber...
-
Brake hose deterioration
Safety risk X164The flexible brake hoses on the GL 320 connect the rigid brake pipes to the brake calipers at each wheel. These rubber hoses are subject to constant flexing as the suspension moves and exposure to heat from the brake discs. MOT data shows this model fails flexible brake hose checks at 6.8x the national fleet average, typically from 100,000 miles. The failure pattern is worsening, suggesting age-related deterioration as the fleet ages.
What to check: Inspect the flexible brake hoses at each wheel for cracking, bulging, or chafing against suspension components. Pay particular attention to where the hose connects to the caliper. Look for any signs of brake fluid weeping from hose connections or along the length of the hose. Check that hoses are...
-
CV joint boot deterioration
Wear item X164The constant velocity (CV) joints at each end of the driveshafts are protected by rubber boots that contain the grease and exclude dirt and water. The GL 320's high ground clearance and off-road capability expose these boots to damage from stones and debris. MOT data shows this model fails CV joint boot checks at 3.7x the fleet average, typically from 100,000 miles. Once the boot fails, contamination destroys the CV joint rapidly.
What to check: Inspect the rubber boots at both ends of each front driveshaft for splits, tears, or missing sections. Look for grease that has been flung out onto nearby components. Check that the metal clips securing the boots are tight and not corroded. Look for any signs of water or dirt contamination inside...
-
Shock absorber deterioration
Wear item X164The GL 320's shock absorbers must cope with the weight of a large SUV and varying load conditions from towing or cargo. The combination of weight and the vehicle's off-road capability places high demands on the dampers. MOT data shows this model fails shock absorber checks at 2.0x the fleet average, typically around 100,000 miles. Failed dampers compromise both handling and braking performance on this heavy vehicle.
What to check: Inspect each shock absorber for signs of oil leakage down the damper body or pooled beneath the vehicle. Fresh oil appears clear while old fluid is dark and sticky. Check the shock absorber mounting points for corrosion or damage to the mounting bushes. Look for any physical damage to the damper ...
-
Environmental fluid leakage
Engine damage risk X164The GL 320 develops oil and fluid leaks from various engine and transmission seals as it ages. Common leak points include the engine oil sump gasket, transmission oil cooler lines, and power steering system. MOT data shows this model fails environmental fluid leak checks at 3.8x the fleet average, with the issue worsening as the fleet ages. While not immediately dangerous, significant leaks can harm the environment and indicate deteriorating seals.
What to check: Inspect the ground beneath the parked vehicle for fresh oil or fluid stains. Note the color - engine oil is black/brown, transmission fluid is red, coolant is typically orange/pink. Check the engine oil level on the dipstick and look for signs of recent topping-up. Inspect visible engine and tran...

Gl 320 questions
What are the main problems with a Mercedes Benz Gl 320?
The most serious known issues are brake pipe corrosion, brake hose deterioration, cv joint boot deterioration. Our car check flags whether a specific Gl 320 has been written off or had insurance claims linked to these faults.
How do I check if a Mercedes Benz Gl 320 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 Gl 320 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 Gl 320 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 Gl 320 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 Gl 320 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 Gl 320 faults that HPI doesn’t include. At £7.49 it’s typically less than half the price of an HPI check.
