We have had numerous electrical and mechanical problems. The fan motor contol module when out,then the module that controls the fuel indicator and display went bad. Now less than 6 mos later the transmisson has gone bad. It is only working in 2 & 3 . No overdrive or first. This last problem suddenly started on 7/17/11. Our mechanic came and checked it out (he did not want us to drive it) and said the transmission was only working in second and third and we should not drive it and needs to be replaced or repaired. We are still paying for this car and for the last repairs on this car. I have seen several complants and service bullitens on this problem and the problem with the gas gauge. Has there been any recalls or acknowledgement of these problems by gm?.
Possible fire hazard and accident due to oil cooler line corroding out. Normal driving. Repair and replacement of oil lines. This was only by shear luck that this was not a serious accident or fire with injuries or death.
