I have a SEAT Tarraco for just over 3 years, having driven just over 18k miles. In all this time I have had no problems to deal with. Autonomous braking has never kicked in apart from me reversing too close the bins inside the car-port. Previous to that I had a SEAT Leon estate and 1 problem, the nearside wheel bearing replaced after hitting a rather large pothole at 65mph on the motorway.
Just hope the replacement Hyundai Kona will be as reliable!
