During his most recent finals, the digital temperature gage in the dash of his Chevrolet Cobalt began to read all dashes. He looked up "no temperature gauge reading" on the Cobalt website and the listed fix was to replace the temperature sensor. He told the service writer the temp sensor was bad according to the website. The first entry on service invoice #CVCS389325 was " Customer states engine temp reading blank". Gainesville Chevrolet Cadillac incorrectly diagnosed the problem and replaced the thermostat which is not responsible for the coolant temp reading out in the dash. The temp gage would still read whatever temperature the engine was experiencing if the sensor was functioning. He left to come home the next day. The Code PO 128 relates to coolant temperature out of normal engine operating range and suggests diagnosing the temperature sensor, thermostat and the PCU. It does not say "replace thermostat" as this dealer did. They came away from reading code PO128 with the faulty assumption the thermostat needed replacing. Several times the coolant temperature reading would go blank in the couple of weeks at home and then there was no temp reading at all. He took the vehicle to the local dealer who diagnosed the temperature sensor to have an intermittent short and replaced it. My son has been to Gainesville and back home three times since the correct repair and the temperature reads out in the dash consistently. The sensor should have been diagnosed initially for the $125 diagnostic fee. I asked the Gainesville Chevrolet service manager to adjust the bill to remove the diagnostic fee since it was originally incorrectly diagnosed. He said no way! This was even though another dealer had to correctly diagnose the problem and correct it by replacing the coolant sensor. Apparently the Gainesville Chevrolet service manager and the operations manager think this is a good way to do business. I can't believe a GM dealer has so little regard for the customer after having done a sub-standard service job. More

The service department wasn't nice from service manager to the mechanics. I was trying to let them address my transmission concern of my chevy car which was still under B2B warranty. This was my second vis to the mechanics. I was trying to let them address my transmission concern of my chevy car which was still under B2B warranty. This was my second visit because the transmission problem became more serious since last visit. I talked to the service manager, he even did not pay attention to me and walked away. Finally, I requested the test drive but the mechanics was also rude. He didn't want to test drive further on the concern. He directly told me that he will not get pay from the test drive and time, so was trying to do is driving out of dealer and driving back. After I showed my anger, then finished the road test with me.
