Thanks for pointing this out Optraowner. I test drove one and I brought my GPS along for the test drive and you are right the speedometer is off and I showed the dealer and guess what he said the GPS is off and I told him to read this forum and I walked out of the dealership.
Thanks Optraowner you saved me from buying a lemon.
GM shame on you for still selling these cars and not letting anyone know about it.
People I suggest you bring a GPS when you test drive any of these models mention by Optraowner as I thought he was just one of them guys that wasn't happy with the car and was making things up but he was right on with the speedometer not telling the right speeds and GM should do a recall or let you know the problem before you buy or lease these cars.
