At least I THINK its an engine noise! I have a 2007 Ford Focus. She’s a lovely car; the first I’ve owned entirely on my own (I’m 64), with a moon roof and stick shift, and she’s red. Since she has front wheel drive I’m not really sure where the noise is coming from. I’ve had a mechanic look at her, but he has not had the time to take her on the freeway, and she doesn’t make the noise at low speeds.
The story is this: When I got the car in October it was very quiet running. New brakes, complete overhaul, about 50K miles, new tires. It was love at first sight. Some engine noise started to develop in late winter and someone told me it was the belt so I had that replaced. The noise was gone at low speeds, but once I got over 50mph it was back and has gotten louder and louder. Now its so loud it drowns out my singing, which is probably a good thing, but still worrisome.The mechanic said at first he thought it was the air conditioner belt but I havent used it or the heater in a month. Then he said he had the same noise in his truck and it had been there for awhile and was not a problem, so he would get to my car when he could and not to worry about it. The noise keeps getting louder. I AM worried about it!
It sounds like a sewing machine on steroids. Like someone has the pedal to the metal on a Singer. It also throbs at times like a cat purring. There is a small range of speed where the noise is less, but thats about 55-58mph and it never goes away at speed. Other than that it’s really loud. And about a “G” on the music scale. I do a lot of highway driving every day and I’m afraid I"m damaging my car. Any suggestions? Any help?
