Known SsangYong Rexton faults
Every fault below is documented specifically for this model — researched and verified before it’s published.
01Frame and Undercarriage Rust Perforation
CriticalOccasionalBody & Rust $1,500–$7,000 to fix
Older Rexton examples — particularly pre-2010 vehicles in NZ's coastal and high-rainfall regions — develop significant rust in the ladder-frame chassis rails, floor pan, and rear body mounts. The vehicle's frame shares construction heritage with the 1990s Mercedes G-Class era and is susceptible to box-section corrosion where drain holes block. Advanced cases fail NZ WoF inspections on structural corrosion grounds.
Symptoms to notice
Visible rust bubbling along chassis rails
Flaking underside rust during inspection
Water pooling in floor area (corroded floor pan drain)
WoF rejection for structural corrosion
What to check
Probe chassis box sections with screwdriver at welded seams and drain holes. Check rear body mount pads and front crossmember. Examine floor pan above exhaust for rust-through. Look for fresh underseal concealing rust. If a workshop inspection is possible: Inspect full underside on hoist.
Where to look: Ladder frame chassis rails, floor pan, body-to-chassis mounts, rear crossmember
Ask the seller
“Has the underside been rust-treated?”
“Does it hold a current WoF with no rust conditions?”
“Has any chassis welding or repair been done?”
02Front upper-arm play and stabiliser-bar wear (Y400)
MinorCommonSuspension $300–$1,500 to fix
On the Y400 Rexton the double-wishbone front suspension tends to develop play in the upper arms after roughly 70,000-100,000 km, and the stabiliser (sway-bar) links/bushes wear quickly enough to be treated as consumables (owners report around 40,000 km service life). The result is clonks over bumps and vaguer steering. Parts are relatively cheap but affect ride, handling and WOF.
Symptoms to notice
Clonk or knock over bumps from the front
Vague or loose steering
Uneven front tyre wear
Rattle from the front on rough roads
What to check
On the drive listen for front-end clonks over bumps. Have someone rock the front suspension or check on a hoist for play in the upper arms and sway-bar links. Check front tyres for uneven wear. Budget for sway-bar links as a wear item.
Where to look: Front double-wishbone upper control arms and stabiliser-bar links/bushes
Ask the seller
“Have the front control arms or sway-bar links been replaced?”
“Any knocking over bumps?”
“Will it pass a WOF now?”

Should I get a pre-purchase inspection on a SsangYong Rexton?
+
Yes. A SsangYong Rexton inspection focused on its known weak points is the single best way to avoid an expensive mistake. KickTyres gives you a guided, model-specific inspection plus a market valuation and negotiation figure for $17.90 far less than the cost of missing one of the faults on this page.
