I do not see any issues on the gauge cluster, the temp sensor is not giving errors so they are not replacing it. The other issue I noticed is the miles the engine light has been on it will count normally.. 300, 301, 302 then jump to 20,000 maybe 50,000 then go to 303, 304, 305, etc..

lastly, I question the Bluetooth connection between the Bluedrive and iPhone not sure if the information sent somehow gets corrupted due to the wireless connection which could also be a factor.
