I purchased my 2007 grand touring roadster 4 months ago, and pleased with looks and performance. I recently have seen my rpm guage sticking or not indicating the correct rpms.I will take this to my dealership,but havent seen this ailment on other threads, am I the only one out there with this problem?

 

Its possible sure. I assure you that you are not the only person to have problems with the tachometer.

 

Chances are that you won't be able to recreate it at the dealer who therefore won't do anything about it. Ask me how I know. It occcurs when the sun is directly behind you. The next time that it happens, put your hand over the tach to block the sun and it should return to normal.

 

Interestin! So the heat makes the plasitc or whatever expand a bit so the needle sticks?

 

I would bet that there is some sort of optical sensor in the tach that is being interfered with by bright sunlight.

 

its happened to me twice....but only happened in cases where it was very hot....once on my way 2 vegas durring the middle of the day, and the other on my way to arizona, also durring the middle of the day, it goes back after a couple of minutes, nothing 2 worry about!

 

Thanks for the unusual tip, funny though it did occur during the hotest part of the day. I cant recall if the sun was bearing down on it,now I will take notice.Unfortunately I live near Seattle and will have to wait 6 months for the heat to come back.

 

that is really weird

 

I've had the same experience and only when the top is down and there's been directl sunlight on the tach. Definitely unnerving the first few times. Now it's just an annoyance.

I had the same problem happen this morning to me. The top was down and it was a sunny but not too hot. I will investigate this further. Thanks for the info...

 

I posted this originally 8 months ago, have seen two other like Threads, so, is this common, no- but it does happen- I wouldnt be concerned. I havent had the issue since....

 

Yeah, I've read about this being an issue before, and it's happened to me a couple times too. Not really a big deal.

 

Yeah I made a thread about this a month ago or so... I have the same problem and seems to only occur when sunlight is directly on the revcounter. It does come back but can happen more than once during a drive too.

So this seems to be a problem among multiple years too...

Oh well its not a huge deal.

 

wow you guys rock. ive been wanting to ask this question for a while, but i just keep forgetting to do so because it happens so rarely. it really pisses me off when it happens though... but thanks for offering the solutions! hopefully i wont ever have to try them out
