Other Fuel System Fuel Injection System problems of the 2011 Toyota Camry

Wed am, Nov. 12, 2014, I parked my 2011 Toyota Camry se 4cyl in an airport parking garage. Weather was 31 f. When I returned from my trip the next evening, I started the car, organized some things for a minute to allow car heater to warm the vehicle while I sat. I then proceeded to back out of the parking space. Temperature was in the 20s f. I noticed the car was sluggish so I pressed a bit more on the gas pedal, but the car failed to go faster. After slowly backing out far enough, I put the car in drive. Despite reaching 2500+ rpm, the car would not increase speed. The speedometer stayed at 0 (zero) mph. I put on my flashers, and pulled, very slowly, to the right side of the garage lane, so as not to impede vehicle traffic. I continued to rev engine for 1 to 2 minutes. Only after revving the engine multiple times did the car begin to slowly respond. This flaw is a significant concern and could endanger live(s). Imagine if I am at a stop sign, awaiting to make a left turn on to a busy roadway. If my 2011 Camry's fuel injector fails to respond as expected, thereby responding slowly to me pressing the gas pedal, then I envision the likelihood of being in a horrific side-impact collision. I will address this issue with the dealership tomorrow. Winter is just beginning, and cold starts are going to be much more common (likely in much colder temps). I don't believe modern vehicles, with electronic fuel injection, should have this safety issue, or require much warm-up time.
