MK74 (2007–2014) — Petrol options included the 2.4 World Engine, with 2.0 CRD on the diesel side. Our database flags 5 known issues on this generation, 2 of which are rated as safety-critical. The most significant concern is Suspension component corrosion and deterioration (£400–£800 to address).
The Jeep Patriot shows exceptional rates of suspension component corrosion and structural deterioration. MOT data reveals failure rates up to 1090.8 times the national fleet average for suspension damage, with load-bearing structure around suspension mounting points deteriorating significantly. This affects both front and rear suspension arms, subframes, and mounting brackets. The issue is particularly severe because it combines with joint wear to create a systemic suspension failure pattern that can affect vehicle safety and handling.
Corroded suspension components can fail suddenly, causing loss of vehicle control. Worn ball joints or deteriorated mounting points compromise steering response and stability. Repair typically requires replacement of multiple suspension components simultaneously due to the systemic nature of the corrosion problem.
Listen for knocking, clunking or rattling over bumps during the test drive. Inspect the underside for corroded or cracked suspension components. Check the MOT history for suspension-related advisories, which often predict future failures.
The Patriot suffers from severe brake system corrosion issues, with brake hose ferrules corroding at 161.0 times the fleet average rate and brake discs showing excessive corrosion and fracturing at 161.0 times the fleet average. The brake lines and flexible hoses are particularly vulnerable to corrosion where they connect to brake calipers and the brake fluid reservoir. This model's brake system appears to have insufficient corrosion protection for UK road salt conditions.
Corroded brake hoses can fail suddenly causing total brake failure on that wheel or complete system failure. Deteriorated brake discs reduce braking effectiveness and can fracture under emergency braking. The car should not be driven if brake system integrity is compromised.
Check brake disc condition for lipping or scoring. Test braking at moderate speed for pulling to one side or vibration through the steering wheel. Review MOT advisories for brake-related items.
Shock absorbers fail at 1090.8 times the fleet average rate, typically due to seal failure causing oil leakage or complete loss of damping function. This issue combines with the model's broader suspension corrosion problems to create poor ride quality and reduced vehicle stability. The shock absorber mounting points are also vulnerable to the same corrosion issues affecting other suspension components.
Failed shock absorbers reduce braking performance, increase stopping distances, and compromise vehicle stability in emergency manoeuvres. While not immediately dangerous, worn shocks accelerate tyre wear and should be replaced promptly to maintain safe handling characteristics.
Listen for knocking, clunking or rattling over bumps during the test drive. Inspect the underside for corroded or cracked suspension components. Check the MOT history for suspension-related advisories, which often predict future failures.
The 2.0 CRD diesel variant shows engine management warning lights at 68.9 times the fleet average rate. This typically indicates issues with the diesel particulate filter (DPF) system, EGR valve operation, or emissions sensors failing to meet expected parameters. The warning light can indicate serious emissions system faults that may put the vehicle into limp mode or cause MOT emissions test failures.
Emissions system faults can cause MOT failure and may trigger expensive DPF replacement or EGR valve cleaning. Vehicles may enter limp mode restricting power and speed. Continued driving with active warnings may cause additional damage to the emissions system.
Check all electrical functions systematically: windows, mirrors, lights, infotainment, heated seats, air conditioning. Look for any warning lights on the dashboard. A diagnostic scan before purchase can reveal stored fault codes.
The 2.4 petrol engine shows exhaust system failures at 1090.8 times the fleet average rate. This typically involves corrosion of the exhaust silencer boxes, flexible sections, or mounting brackets causing exhaust leaks or the system becoming insecure. The exhaust system appears to have insufficient corrosion protection for UK conditions and may require earlier replacement than typical vehicles.
Exhaust leaks can allow dangerous fumes into the cabin and will cause MOT failure. A completely detached exhaust poses a road safety hazard to other vehicles. Repair typically involves replacement of the affected section rather than temporary patching.
Check for any engine warning lights on the dashboard. Ask about the car's MOT emissions history — repeated failures suggest underlying issues. A pre-purchase diagnostic scan is especially worthwhile to check for stored emissions fault codes.

Based on 5k real DVSA MOT tests, the Chrysler-Jeep Patriot fails more often than average on several items. The biggest outlier is suspension ball joints worn at 86x the fleet average, followed by emissions failure (57x).
When viewing a specific car, check its MOT history for recurring advisories in these categories. See the full Chrysler-Jeep Patriot MOT failure breakdown for data at every mileage point.
Routine servicing (oil and filter change every 10k miles) typically costs £80–£120 at an independent garage.

The Chrysler-Jeep Patriot has some well-documented weak points, including 2 safety-critical issues that demand careful checking. The right example, properly maintained, can still be a sound purchase — but cutting corners on the pre-purchase inspection is not advisable.
