NHTSA Complaint #10474012 — 2012 CHEVROLET SONIC

MULTIPLE REPORTS OF DAEWOO SONICS (AND CRUZES, ALSO SOURCED FROM DAEWOO THOUGH ASSEMBLED IN THE UNITED STATES) EQUIPPED WITH THE 1.4L TURBOCHARGED ENGINE STALLING OUT AND/OR ACCELERATING POORLY IN WARM/HOT CONDITIONS WHEN USING 87 OCTANE FUEL. THESE VEHICLES ARE UNSAFE IN WARM WEATHER WHEN OWNERS USE REGULAR, UNLEADED GASOLINE, EVEN THOUGH THE MANUFACTURER DOES NOT PROHIBIT LOW OCTANE FUEL FROM BEING USED. (PREMIUM FUEL IS "RECOMMENDED" BUT NOT REQUIRED, AND THE DEMOGRAPHIC GROUPS THAT WILL PURCHASE THESE CARS LIKELY WILL NOT WISH TO SPEND ADDITIONAL MONEY FOR PREMIUM FUEL FOR ECONOMICAL, SUBCOMPACT AUTOMOBILES.) NHTSA NEEDS TO INVESTIGATE THESE EXAMPLES OF GOVERNMENT MOTORS ONCE AGAIN ENDANGERING THE GENERAL PUBLIC. *TR
