TF_Gen1 (1997–2019) — Engine options included the 2.5 Diesel. Our database flags 5 known issues on this generation, 2 of which are rated as safety-critical. The most significant concern is Chassis spring fracture (£200–£400 to address).
The coil springs or leaf springs fracture at an exceptionally high rate on this model, with MOT data showing failures at 337 times the national fleet average. This affects all mileage bands from 40,000 miles upwards and is worsening year-on-year. Spring failure on a commercial vehicle can cause sudden loss of control, especially when loaded, and represents the most dangerous documented failure mode for this model.
A fractured spring can separate completely during driving, causing sudden loss of vehicle control, wheel misalignment, and potential contact between tyre and bodywork. On a loaded commercial vehicle this presents extreme danger. Immediate replacement required - vehicle should not be driven with suspected spring failure.
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.
Vehicle structure corrodes to the extent that rigidity is seriously reduced, with failures occurring at 23 times the national fleet average. This affects the load-bearing structure within 30cm of towbar mounting points at 53 times the fleet average. Commercial vehicle exposure to salt, moisture, and loading stress accelerates structural corrosion, particularly around chassis mounting points and load-bearing sections.
Structural corrosion reduces the vehicle's ability to handle loads safely and may compromise crash protection. In severe cases, mounting points can separate under load, causing loss of vehicle control. This is a dangerous defect requiring immediate professional assessment. Vehicle should not carry maximum payload until repairs are completed.
Inspect the wheel arches, sills, jacking points and door bottoms carefully. Press gently on sills to check for soft spots. Look underneath for corrosion on structural components. Check the MOT history for corrosion-related advisories or failures.
Suspension pins, bushes and joints wear at 269 times the national fleet average, making this the second most common MOT failure point. The high failure rate affects all mileage bands from 40,000 miles and is worsening consistently. Commercial vehicle duty cycles and payload stress accelerate rubber bush degradation, leading to poor handling, tyre wear, and potential MOT failures.
Worn suspension bushes cause poor vehicle control, accelerated tyre wear, and MOT failure. While not immediately dangerous, deterioration of multiple bushes significantly affects handling safety, especially on a loaded commercial vehicle. Replacement costs multiply if multiple components need attention simultaneously.
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.
Wheel bearings develop excessive play at 37 times the national fleet average, affecting all mileage bands from 40,000 miles upwards. Commercial vehicle loading and duty cycles accelerate bearing wear, particularly in the rear axle which carries the primary payload. Failed bearings cause noise, vibration, and potential wheel detachment if not addressed promptly.
Worn wheel bearings cause noise, vibration, and uneven tyre wear. Complete bearing failure can result in wheel detachment, representing a severe safety hazard particularly on commercial vehicles. Replacement typically requires specialist tools and bearing pullers, making this a workshop job rather than roadside repair.
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.
Shock absorber bushes wear excessively, failing at 21 times the national fleet average across all mileage bands from 40,000 miles. The trend is worsening year-on-year. Commercial vehicle duty cycles and payload stress cause rubber bushes to deteriorate faster than passenger car applications, leading to poor ride quality and MOT failures.
Worn shock absorber bushes cause increased road noise, poor ride quality, and reduced suspension control. While not immediately dangerous, they accelerate wear of other suspension components and can cause MOT failure. Replacement is typically straightforward but may require removal of the complete shock absorber assembly.
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.

Based on 9k real DVSA MOT tests, the Isuzu TF fails more often than average on several items. The biggest outlier is coil springs broken at 338x the fleet average, followed by towbar fault (233x).
When viewing a specific car, check its MOT history for recurring advisories in these categories. See the full Isuzu TF 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 bigger-ticket items to budget for include timing belt (£400–£600).
