I know this sounds funny, but my new RL makes a high-pitched and quite audible whistling sound whenever my speed is over 70 mph. More specifically, when I take my foot off the accelerator and coast the whistling stops but it starts again as soon as I press on the gas. A friend of mine had the same problem in an Infiniti a few years back so he thinks it may be common in Japenese cars. Has anyone heard of this before or better yet is anyone experiencing this in an '05 RL? It's driving me nuts. I turn my radio up but I can still hear it. It's not loud, but it is loud enough to hear. A number of people who have ridden with me in the car have pointed it out to me. I'm due for service in 1500 miles but I may have to take it in sooner.
