Here's the deal, my girlfriend bought a new Volvo S40 about 10 months ago and we have had it in the shop three times because the airbag service required light keeps coming on, last time it was in was last Monday and it just came on again. Truth be told it has never stayed off for more than a month or two but we got lazy last time and didn't take it in for a month or two. So now it is going in for the fourth time in tem months, at what point do we say shine it and tell them to buy it back?
