I have had multiple problems with this car: 1) engine/throttle system: a) intermittently, the car will not start when the engine is warm, whether from driving or it is a hot day. I had it towed to the Volvo dealer from my garage when it had <20k miles and was told that I was not driving it hard enough. They advised that the engine had to be blown out and suggested that I rev-up the engine while the car was in park to clean it out. That did not help. I have had the car serviced multiple times. The problem had gotten so bad, that the car began stalling while I was driving it, particularly, if I stopped for a traffic light or turned a corner. I paid $1,500 in January 2005 to have it repaired again, and now the problem is back. The Volvo dealer is useless. B) the engine either leaks or burns oil. I will intermittently hear a clicking noise to find out that all of the oil is gone. The oil light does not come on. I routinely have to add 3-4 quarts of oil. 2) safety features: the rearview mirror broke off in my hand and I was told by the dealer that it was a safety feature. When it broke off, it left a metal spike sticking out that would have done far more damage in an accident than the mirror. The child lock on the rear center seat belt failed. I took it to the dealer and was told that I was pulling the belt too tight and it was supposed to have some "give". Of course, I know that the child seat is not supposed to wiggle around in the back seat, so I insisted that it be replaced. Body: the mechanisms to hold up the trunk lid no longer function. The latch to release the hood has had to be replaced.
