Octane ratings are more than just stickers posted on gas pumps; they have a pretty important purpose too, and one that - if not used the right way - could lead to problems for the 2010 Cadillac SRX crossover.
According to General Motors, the SRX, which comes with a turbocharged 2.8-liter V6 engine, could have a pretty embarrassing chink on its armor wherein putting in gasoline with an octane rating that’s lower than 91 could lead to some pretty serious problems causing pre-ignition. As such, GM is trying to nip the problem in the bud by recalling about 547 SRX crossovers that have been tagged by the NHTSA as potentially having this deficiency.
So if you happen to own a 2010 Cadillac SRX crossover, you might want to head over to your GM dealership to have your Engine Control Modules reprogrammed at no cost.
NHTSA press release after the jump
GENERAL MOTORS IS RECALLING CERTAIN MODEL YEAR 2010 CADILLAC SRX EQUIPPED WITH A 2.8L V6 ENGINE. IF LOW OCTANE (REGULAR) FUEL IS USED IN THE VEHICLE INSTEAD OF THE REQUIRED HIGH OCTANE (PREMIUM) FUEL AS STATED IN THE OWNER MANUAL AND ON THE FUEL FILLER DOOR, THE COMBINATION OF REGULAR FUEL USAGE AND AGGRESSIVE DRIVING MANEUVERS MAY INDUCE PRE-IGNITION. IF PRE-IGNITION OCCURS, YOU MAY HEAR A PINGING OR KNOCKING SOUND FROM THE ENGINE.
IF THE VEHICLE CONTINUES TO BE DRIVEN AFTER THE ONSET OF THIS NOISE, A CONNECTING ROD OR PISTON MAY BREAK, RESULTING IN ENGINE DAMAGE, AND PERHAPS ENGINE FAILURE, WHICH WOULD DISABLE THE VEHICLE INCREASING THE RISK OF A CRASH.
DEALERS WILL REPROGRAM THE ENGINE CONTROL MODULE FREE OF CHARGE. THE SAFETY RECALL IS EXPECTED TO BEGIN ON OR BEFORE JUNE 11, 2010. OWNERS MAY CONTACT THE CADILLAC CUSTOMER ASSISTANCE CENTER AT 1-866-982-2339 OR AT THE OWNER CENTER AT WWW.GMOWNERCENTER.COM.
