Question about 2007 Pontiac Vibe
Hi there. The speedo on my new Vibe (2009 GT) is 3-5 mph off, depending on my speed, 5 mph difference at 65 mph. The dealer tested and confirmed the discrepancy but says GM won't authorize a fix because it's a recalibration and they're not authorized to recalibrate. I complained enough that they went ahead and replaced the fly wire (whatever that is) but it didn't change anything. The dealer also tested other models on their lot and find the same thing in all of them.
My question to you is, can you explain why GM can't fix this? As far as pursuing my complaint, it's already been given case numbers by GM and the California Attorney General. I'd feel better if I understood why GM won't touch this. Thanks. P.S. Your product field would only accept 2007.
Because pontiac vibe is a toyota matrix clone and both are made in two different places/countries I guess pontiac ( better looking one - new model :) has different size tires . Speedometer is calibrated to standard size tires . If you have smaller or bigger you will see some differences. Of course it may be few other things but let's start with the simplest one. Good luck

It's common in ALL models of Vibe/matrix/corolla. its due to a last minute tire size change by the manufacturer. they used 205-55-16, instead of 215-55-16.that 10mm different in tire, makes up for the 3-5 mph reading.
i had gotten ahold of the 2003 dealer specs booklet from pre launch of the vibe, and it stated the STOCK tire size, was 215-55-16
By putting 205 instead of 215 on the cars, they saved about $20 per tire, in the final cost of the vehicle, and still charged full tire price.

The tire size is listed on the b-pillar, door or under the hood. Smaller circumferences cause the speedometer to run faster and the adverse. The japaneeze normally set the spedometer differently through the break in period. After this period the flash is modified to accommodate. Since this is a toyota there is no repair at the GM level. No and you may not take this vehicle to toyota, they will send you to GM. This is the chances you take when you purchase a foreign vehicle.

Check out PIC3100B - Odometer Accuracy. After seeing the same probem with my new 09 Vibe, they replaced the dashboard cluster. After calls to GMC by the dealer, there were told about this bulletin that was just recently updated (imagine that).
Says a tolerance of plus of minues 4% in accuracy is allowed.
I've been trying to find a complaint form on Pontiac's site as I consider this unacceptable but I can't get to it...it magically times out.
Anyone else have an idea?

I have the same problem and all i can tell you is that the tire size for the 17in. rims is the same as the 18 in. rims p215/45R18 and P215/45R17 this will throw the speedo off.
