One problem related to radiator hose has been reported for the 2005 Volvo S40. The most recently reported issues are listed below.
I have a 2005 Volvo S40 2. 4i with about 47k miles and I am having problems with the a/c. I live in houston (TX) where it gets very hot so I have to have the a/c on constantly. When I first turn the car on and drive off, the a/c starts cooling and working just fine. However, when it is 90f or above, the a/c begins to blow warm air after a few minutes. When that happens I have to turn it off and back on a few times to get it working again but it only works for a few minutes before I have to repeat "on/off" ritual. Usually, if I leave it off for a few minutes it works for a bit longer time before it stops again. This problem 1st appeared when it was about a year old @ about 9-10k miles but it only happened once and was fine after I turned off and back on. 2nd time happened about 1-1/2 yrs ago when it was around 35k miles but was the same as the first time and was ok after turning off and back on. Now for the past year it is constant!! this happens daily!! the car is only now 47k. I took it to the car dealership yesterday and I barely began explaining the problem and before I even finished describing it, the service advisor finished by telling me the rest. He told me he knew the story b/c he heard it many times before. He said it was most likely the compressor clutch, compressor, or both. He said that it is a constant problem with that vehicle and that they do the same repairs repeatedly and that it seemed like a specific problem on those vehicles. Today, I began doing some research and found several sites where people are asking online advisors what this problem could be. Per my online research and the dealership's service advisor this is a very common problem with this car. Since this is such a common problem with the car can you please look into doing a product recall for these faulty parts so that we're not stuck paying the estimated $1500 at the dealership! thank you ([xxx]) information redacted pursuant to the freedom of information act (foia), 5 u.
