Etc (electronic throttle control) when this light comes on flashing it goes into limp mode (idle) this is a real safety concern especially in traffic when towing a trailer. i bought the truck new from city auto plaza, canon city, co. i brought the truck into city auto plaza june 4th 2014 when the etc light was flashing. they replaced the gas pedal the following day the etc light came on. june 11th 2014 they re-crimped the plug on the pedal sensor and the c130 connector under the hood. that lasted about a month and a half. on july 29th 2014 they hardwired around the c130 connector. that lasted about 8 months brought truck in on march 9th 2015, the etc light had gone off by the time i got to city auto plaza but it was the same code in storage p2121. the etc light came on again in may 12th 2015 brought it back and they re-crimped the pedal sensor put some lube and pulled the plugs off the pcm and blew they out and put some lube in the plugs. july 8th 2015 the etc light came back on flashing so i brought it down to city auto plaza again and they hardwired from the gas pedal all the way to the pcm. that lasted 2 days and the etc light came back on going into limp mode. brought it in again on july 16th the light was off. they test drove it numerous time couldn't get the etc light to come on but it still had the same code in storage p2121. so the swapped out accelerator pedals got the truck back on the july 21st. on july 29th i brought the truck in to troubleshoot the ac (air conditioner) started the truck in the parking lot and the etc light was flashing. travis the tech that works on my truck has brought in tech support from chrysler. travis also google'd it and this is not just my truck. he saw trucks from 2004 to 2009 with these same problems. why can't chrysler figure this out? does someone have to get in and accident or die before they figure it out?
I own a 2008 3500 diesel megacab dually . i was driving along i-70 in colorado at about the speed of 75-80 mph and had to step on the gas pedal all the way down to get around a semi-truck and as soon as i did this the gas pedal got stuck. i know it wasn't stuck to the floor-mat because i visually saw that it wasn't. i had to slip my shoe off and pull the gas pedal up with my toes due to the shoe not being able to get behind the pedal. by the time i managed to pull the gas pedal back my truck had sped up to about 110-115 mph.. this is the second time that this has happened to me. previous to this incident about a week and a half earlier this happened to me in denver as i was be driving through the city. i thought it was the floor-mat then, so i ignored the fact that this had happened but this second time around i did look down to see if it was or not the floor-mat and it was not the floor mat.... i did not have the cruise control on at either time.. im going to try to contact chrysler and the dealer to try and see what they believe it might be.. odds are they will think i'm imagining things !! *tr
