In a completely expected move, General Motors has just recalled 2010 Cadillac SRX crossovers that are equipped with the turbocharged 2.8-liter V6 engine due to the possibility of engine failure. The problem stems from the misuse of gasoline with lower than the required 91 octane rating. If driven aggressively with non-premium fuel, pre-ignition may be induced.
Such cases of pre-ignition can be very serious, with broken pistons or connecting rods standing out as possible results... as was found out not long ago by Automobiles De Luxe after mistakenly filling Caddy's latest 'ute with 88 octane fuel instead of the required 91 octane.
Owners of the 547 affected vehicles are being directed to get their Engine Control Modules reprogrammed free of charge from their favored dealer. More information can be found in the National Highway Traffic Safety Administration's notice after the break.
If the reprogram only intervenes when a pre-ingition is detected then I am all for the recall. If the reprogram detunes the engine whether ping is detected or not, I feel that this should not be invoked because of driver error. (Note; the condition can occur if lower octane is used and the operator continues to drive at aggressive levels.)
