Customers may experience one or more of the following: ● Slow acceleration. ● Reduced vehicle speed \& torque in high and 4 low. ● Poor cold idle stability. ● Poor idle quality with AC on. ● Excessive engine speed oscillations at tachometer red\-line. ● Following a long key\-on situation, poor cold start and idle stability. ● Cold hard start/extended crank. ● Block heater not providing a proper cold start and stable idle. ● High idle speeds at altitude when remote start is active. ● The cruise control and speed limited set speed doesn’t match the speedometer. It could be up to 2.5 kph \(1.5 mph\) difference. Other Software enhancements: ● Low speed engine idle improvements. ● Improved engine restart performance and torque response during low fuel level and/or hot ambient conditions. ● Corrects instances of vehicles restarting once SRC Inducement is active, and the mileage countdown has expired. ● Reduce engine delay during cold start garage shifts. ● Improve idle stability, Improvement of cold start and combustion stability after start during cold ambient temperatures. ● Eliminate turbocharger surge on tip\-out. ● Eliminate idle oscillation in park and drive. ● Speedometer accuracy improvement\(s\). ● Cruise control updates. ● Battery durability improvements in hot ambient temperatures. This bulletin involves reprogramming the PCM with the latest available software."
