Someone outside my truck, on start up, commented on the engine rattling and then getting quite. I looked it up and found it to be a common issue, with timing chain stretch and VCT actuators being bad. I have extended warranty on my 2013 F150, 43K miles. I have a recall on a speed sensor in the trans and trying to get in for evaluation. Any first hand experience on this? My research shows it on going from 2011 up to 2019.
