High Pitch Sounds When Driving

Has anyone else experienced occasional high pitched whistling sounds when driving or breaking. I've had this problem for the past 2 weeks and it's starting to become very annoying. I haven't had a chance to bring it to the dealership yet. Does anyone have an idea what's causing this?

Thanks,

Eric

Re: High Pitch Sounds When Driving

brakes good chance in the front. At what mph do the sounds start/end? Did the sound build over time? Mine happened when I was 30-50 mph and got worse as time went on. I had to take apart the calipers and "greece" everything up, then it was all good.

Re: High Pitch Sounds When Driving

The AC and ventilation system make turbine and whistle sounds at times. Tow/Haul mode seems to add its own turbine sounds.

Re: High Pitch Sounds When Driving

I know exactly what you're talking about. It bugs the hell out of me. It only occurs when the air conditioning is on for me and it seems to be right around 1200 RPMs. It only occurs when accelerating or braking. It's really high pitched and some people don't notice it, but I do. I think it has something to do with the HVAC system and its connection to the engine...

sorry i havent had a chance to respond...apparently i dont have enough posts to respond to messages...go figure.

but hopefuly the dealer you are working with has had similar complaints...i would just point to the TSB to fix it...good luck.

im waiting for an oil change or another reason to go back to the dealer...once i do, ill post how it went...
