Complaint Summary
POWER TRAIN
Owner Narrative
Without any indications of a problem our transmission began making a loud whining noise. The evening before it was fine and the next morning on startup the noise just began. The Vehicle only has 45,000 miles on it and the transmission had been serviced at the recommend manufacturer interval. Took it immediately to my auto repair shop where it was diagnosed as a transmission failure (they has seen this before) and told not to drive until replaced due to safety issues related to the failure. Unfortunately, due to a shortage of these needed 10 speed transmission I waited over a month for the vehicle to be repaired. The shop contacted GM to inquire about any warranty help but was told there was none.
