The paint is peeling off my 2015 Holden Barina hatch in sheets. Why would this be happening? I purchased the car brand new off the lot, and it has always been garaged when not being used.
Let me guess: Your car is white, yes? This has been a real problem, not just for Holden, but also Toyota, Kia, Hyundai and even Honda (and possibly others) around the world. The problem is a chemical one in the white paint being used and it leads to delamination of the paint layers, with the white top coat either flaking, chipping or peeling off in great swathes.
Even some other colours have been noted succumbing to this process, but white seems to be the worst offender. Whether the problem is with the car’s preparation at the factory a function of a poor batch of paint from the supplier isn’t really known, but the finger is being pointed at the latter. Either way, it effectively destroys the resale value of your car as well as laying the car’s structure open to the elements.
The best advice is to contact Holden’s customer service department and perhaps even have the car professionally inspected (your state motoring club is a good place to start here). In the past, carmakers have been known to repaint affected cars at their own cost which, given your car’s garage history, shouldn’t be out of the question.
