The Mahindra Thar is not just an SUV in India—it’s an emotion. From city streets to Himalayan trails, the Thar has built a cult following. But once the excitement of ownership settles and the odometer crosses 40,000 km, reality begins to show up.
After speaking to multiple long-term Thar owners, independent garages, and Mahindra service advisors, this Mahindra Thar long-term review takes a brutally honest look at what actually happens after 40,000 km—the good, the bad, and the inconvenient.
If you’re a current owner or planning to buy a used Mahindra Thar, this real-world guide will help you make informed decisions.
Engine Performance & Reliability After 40,000 km
Mahindra offers the Thar with 2.0L petrol and 2.2L diesel engines, both proven units—but long-term ownership reveals clear differences.
Diesel Engine (2.2 mHawk)
- Remains mechanically strong even after 40,000 km
- Power delivery feels slightly less aggressive than the new one
- Turbo lag becomes more noticeable if maintenance is delayed
- Injector cleaning and EGR valve issues are reported in city-driven vehicles
Owners who stick to timely oil changes and genuine filters rarely report major failures. Diesel cars are used heavily for off-roading and show faster wear on mounts and hoses.
Petrol Engine (2.0 mStallion)
- Smoother than diesel, but fuel efficiency drops faster
- Carbon buildup complaints in traffic-heavy usage
- Higher heat generation leads to earlier rubber component aging
Verdict: In terms of Mahindra Thar reliability, the diesel engine ages better for Indian conditions.
Suspension Wear on Indian Roads
Indian roads are the true test for any ladder-frame SUV.
After 40,000 km, common suspension-related complaints include:
- Front suspension knocking sounds
- Worn-out stabilizer link rods
- Shock absorbers are losing damping efficiency
- Faster bushing wear due to the stiff factory setup
Those driven regularly on broken roads or trails show suspension fatigue earlier than rivals like the Force Gurkha, which has a softer stock tune.
Many owners opt for aftermarket suspension upgrades around this mileage to restore comfort and improve control.
Clutch, Gearbox & Drivetrain Issues
Manual Transmission
- The clutch pedal becomes heavier
- Clutch replacement is required between 35,000 and 50,000 km for city users
- Gear shifts feel notchy, especially 2nd to 3rd
Automatic Transmission
- More reliable in traffic
- The torque converter holds up well
- Delayed response during aggressive overtakes after long usage
Drivetrain components like prop shafts and universal joints show wear faster in Thars frequently used for off-roading without proper post-trail inspection.
Steering Feedback & Handling Concerns
The Thar’s steering is designed for rugged terrain, not sharp handling.
After 40,000 km:
- Increased steering play reported
- Reduced self-centering effect
- Alignment issues due to suspension wear
Compared to monocoque SUVs like the Jeep Compass, the Thar feels less confidence-inspiring at highway speeds as it ages.
Interior Quality, Rattles & Comfort Issues
This is where expectations often clash with reality.
Common complaints include:
- Dashboard and door rattles
- Loose panels near the rear seats
- Seat cushioning flattening
- Increased wind and road noise
Water-resistant interiors help in off-road use, but long-term daily use exposes the average material quality.
Owners expecting Fortuner-level interiors are often disappointed.
Fuel Efficiency Drop Over Time
Fuel efficiency reduction after 40,000 km is noticeable:
- Diesel: Drops by 1–2 km/l
- Petrol: Drops by 2–3 km/l
Causes include:
- Injector wear
- Throttle body deposits
- Increased rolling resistance due to suspension wear
Regular engine tuning helps, but the Thar will never be a mileage-focused SUV.
The Maintenance & Service Cost in India
Average Costs (Post 40,000 km)
- Annual service: ₹12,000 – ₹18,000
- Clutch replacement: ₹18,000 – ₹25,000
- Suspension overhaul: ₹20,000+
- Brake pads & discs: ₹10,000 – ₹15,000
Mahindra service quality varies widely across cities. Many owners shift to trusted independent garages after warranty expiry.
Long-Term Off-Road Usage Impact
Regular off-roading accelerates wear on:
- Bushings
- Driveshafts
- Differential seals
- Wheel bearings
Owners who don’t inspect and lubricate components post-trial face higher repair bills later.
Common Owner Complaints vs Expectations
Expectation: A comfortable daily SUV
Reality: A lifestyle off-roader with compromises
Expectation: Low-maintenance, rugged vehicle
Reality: Needs attention if driven hard
Expectation: Premium feel
Reality: Function-first design
Understanding this difference is key to enjoying long-term Thar ownership.
Is the Mahindra Thar Reliable After 40,000 km?
Yes—mechanically, the Thar remains reliable if:
- Proper service intervals are followed
- Off-road use is responsible
- Preventive maintenance is not skipped
However, comfort and refinement decline faster than many buyers expect.
Should You Buy a Used Thar With 40,000+ km?
✔ Yes, if:
- Full service history is available
- No major off-road abuse signs
- Suspension and clutch condition checked
❌ Avoid if:
- Heavy modifications done poorly
- No warranty or insurance transparency
This used Mahindra Thar buying guide advice can save you lakhs.
Manual vs Automatic: Long-Term Reliability
- Manual: Cheaper to repair, but clutch wear is inevitable
- Automatic: Better for city use, higher repair cost if neglected
For long-term ownership, the automatic is more stress-free in Indian traffic.
Final Verdict: Is the Thar Worth It After 40,000 km?
The Mahindra Thar remains a strong, capable, and reliable SUV after 40,000 km—but it demands understanding and commitment.
It’s not for everyone.
It never was.
If you accept its compromises, maintain it properly, and upgrade wisely, the Thar can easily cross 1 lakh km with pride.
