I purchased my Terracan 2.9CRDI Dec 2005,
It has never missed a beat, its more than a match for the most rugged terrain that I can find here in NZ. My previous 4x4 was a Isuzu Vehicross an astounding functional and capable offroader, The Terracan does the same job, but with more traction (heavier) an thus unstoppable... Hyundai must have fixed the suspension as my Terracan handles the road as good as any 4 door car in-fact my travels up and down 90Kms of the worst road in NZ (Parapara track) have never been safer or faster than in the Terracan all while averaging 35Mpg of desiel
I too have a terracan 2002 model. At the time of purchase, it was a great vehicle and for the first 18 months, it never skipped a beat.
Wait until it hits about 100,000km's. System failure!!! My terracan has been into the dealership approximately 30 times since March this year - and still they have no idea what is wrong with it.
This pattern continues, until I tell them numerous times what the problem is, then the vehicle is returned to me in a worse state with further problems.
I am going back - again - to Hyundai, tomorrow, to try and rectify the problem - again!!!
I suspect that there are numerous problems with it, including the suspension, or lack thereof, continuous pinging, and a constant vibration through the car at all speeds resulting in driving a vehicle that feels like a wheel is about to fall off.
Well, wish me luck. Oh, and don't say you weren't warned.
