I recently experienced the conditions described by the gm recall 14515 in my 2009 chevrolet suburban 1500. in the past 6 weeks, the car has failed to start. the first incident required nearly 10 minutes of starting the car before it would start. once started the car was fine. it was a cold start - first thing in the morning. about a month later it failed to start gain, after being parked for approximately 2 hours. again, after about 10 minutes, the truck started and drove fine afterwards. today - about 2 weeks after the 2nd incident, the truck stalled while my wife was at a stop light. it took 6-7 attempts to start before the truck again fired up and was able to be driven. this condition is exactly what is described in gm recall 14515. however, gm is saying that my vehicle (vin: [xxx]) is not covered in the recall. i think that an error and disagree with how nhtsa and gm determined which cars are affected.... i am appalled that gm is able to get away with this. information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6). *tt
While driving, vehicle suddenly goes into "reduced engine power" mode ("limp mode") with console message "traction contol disabled, service stabilitrak, engine power reduced". generally occurs when temperatures are lower than 25 degrees farenheit. shutting down vehicle for several minutes and restarting leads to normal operation, however vehicle will generally repeat same problem within 5-15 minutes if outside temperature is cold enough (below 25 degrees farenheit) . error code p1235 (throttle position sensor 1-2 correlation...) is set, but may not persist in memory. gm is providing owners with additional protections for 10 years/120,000 miles under csc-10047220-3332 (bulletin no. 11273), however not all vins are included. vehicle had throttle body (including sensor) replaced in 2010 and appears to be exhibiting exact problems covered by this bulletin, however gm dealer and gm are not extending protection for this vehicle. dealer is recommending another new throttle position sensor and/or throttle body (including sensor), along with computer reset. this intermittent problem has occurred for more than three years and poses a significant safety risk when the vehicle is in motion at normal highway speeds (drastic sudden deceleration in traffic).
