When I use my right turn signal it will blink normally three times and then quick blink with a pop up “Right rear turn indicator failure” even though the lights all work fine on the outside. I’ve replaced the harness and tried new bulbs and nothing has fixed it. Additionally, my rear right brake light does not work even though the bulb is fine, i wasn’t sure if maybe these two issues could be connected. Any help is much appreciated, thank you. ]]> 2014 - 2018 (GMT-K2) elirey https://chevroletforum.com/forum/2014-2018-gmt-k2-110/lighting-wiring-troubleshooting-121869/ https://chevroletforum.com/forum/2014-2018-gmt-k2-110/mpg-drop-silverado-121856/ Sun, 26 Apr 2026 23:37:49 GMT New to this forum and looking for info on why my 2016 Chevy Silverado with a 5.3L engine and 183K miles has significant mpg drop (City 19mpg has dropped to 13 mpg).

New to this forum and looking for info on why my 2016 Chevy Silverado with a 5.3L engine and 183K miles has significant mpg drop (City 19mpg has dropped to 13 mpg). I’ve had it to shop and they say there are no codes showing. I have recently changed spark plugs and wires, cleaned throttle body and injectors. I have checked my mpg using truck digital screens and also completed mpg calls manually. Both numbers match. I’ve recently had alignment checked and that was ok. Shop claims that bad MAF or Oxygen sensors would throw codes but no codes are showing. Looking at other things to check. I’m going to change my thermostat this week. Current operating temps running between 178 and 181 degrees. ]]> 2014 - 2018 (GMT-K2) McChevy67 https://chevroletforum.com/forum/2014-2018-gmt-k2-110/mpg-drop-silverado-121856/
