Top issues to watch for

The most serious Suzuki Grand Vitara problems ranked by severity. We track 5 known issues — here are the ones you need to know about first.

Dangerous
Subframe mounting point corrosion
FT, JT1998–201520k–150k miles
The chassis mounting points where the front and rear subframes attach suffer from severe corrosion that can compromise structural integrity. This affects the prescribed areas within 30cm of suspension mounting points. MOT data shows this model fails at 110.6 times the fleet average for mounting point corrosion, with additional failures for load-bearing structure weakness. The problem appears across all engine variants and mileage bands, indicating a fundamental design or material issue.
What happens if ignoredIf subframe mounting points fail, the vehicle becomes extremely dangerous as the engine, transmission, or rear axle assembly can separate from the body. Repair requires welding new metal into the chassis structure, typically costing £1,500-£3,500 depending on the extent of corrosion. The vehicle is not safe to drive if structural weakness is suspected.

Major
General body structure corrosion
FT, JT1998–201540k–150k miles
The vehicle structure suffers from widespread corrosion that can reduce rigidity to dangerous levels. This affects door pillars, sills, rear crossmembers, and other load-bearing sections. The problem occurs across all engine variants and appears to worsen with age regardless of mileage.
What happens if ignoredSevere structural corrosion compromises vehicle safety in a collision and can lead to MOT failure. Body shell repairs typically require professional welding and can cost £800-£2,500 depending on the extent of damage. The vehicle may not be economically repairable if corrosion is extensive.

Major
Suspension bush and joint wear
FT, JT1998–201560k–150k miles
Suspension pins, bushes, and joints wear at an exceptionally high rate on this model. MOT data shows failures at 66.2 times the fleet average, affecting both front and rear suspension components. The problem appears across all engine variants and can occur even at relatively low mileages. Common failure points include front wishbone bushes, rear trailing arm bushes, and anti-roll bar links.
What happens if ignoredWorn suspension components affect handling safety and cause uneven tyre wear. Multiple bush replacements can cost £600-£1,500 depending on which components need attention. The vehicle remains driveable but handling deteriorates progressively.

Major
Suspension component corrosion
FT, JT1998–201560k–150k miles
Suspension components suffer from excessive corrosion damage that can compromise their structural integrity. MOT data shows failures at 47.5 times the fleet average for suspension component corrosion. This particularly affects steel wishbones, trailing arms, and mounting brackets where road salt and debris accumulate. The problem appears worse on vehicles used in harsh winter conditions.
What happens if ignoredSeverely corroded suspension components can fail suddenly, causing loss of vehicle control. Replacement of corroded arms and associated components typically costs £500-£1,200. The vehicle should not be driven if structural suspension damage is suspected.
