It just failed, they first thought it was the foot position sensor. Replaced foot pedal, drove 20kms same thing happened. Replaced throttle body never looked back.

Be your throttle body. Had the same thing happen to my 5.3.

Week tops

Sorry guys. The email link took to wrong thread.

Ya , very well could be. id Be asking again. I was the orginator iof this thread and after mine first blew I thought it would be fine with a replacement part. About 8-9 months after the replacement line was installed I got a recall letter saying they would replace the defective line again. I asked service manager and they replaced it with the same line that was from the faulty place to begin with so it could of happened again.you assume the new peice they put on wont be defective again. Always been a gm guy but these new 19-20 trucks are something special. At least my dealership was good with the constant breakdowns and giving me a loaner.

And your dealer is waiting for the new oil line and taking 5 months?

This has been happening to me for the last 5 days on a 2019 trail boss with 65000 kms. I leave my truck with fob in hand and about 10mins later it gives me 3-5 quick honks, like super quick. No idea why it’s doing it. Leave key fob in house, go out to investigate, trucks locked, no lights on dash like something is on. Yesterday morning I started the truck, went to back up Out of the driveway for work and my steering wheel was locked. Cycled off, on. Still locked. Another cycle, same thing.... locked. No lights on dash, nothing, Everything else was normal. Came home after work, started it and it was normal again. Had steering. No idea. Hate this truck

I have 64000kms on my 19 trailboss. Never had an issue with this System at all. Went to dealer for something different and they did the brake recall. Now truck has all the lights on, engine power reduced, service ecs, check engine, abs lights.

hi, I’m the original person who started this thread, was just at my dealer for an oil change and they told me there’s a recall on my truck for these oil cooler lines for a different design. Even though they put a new one on after my original one failed they said this one could fail too cause it’s the same hose.

Sounds like the same thing that was happening with mine. Been 4000kms since the ecm was replaced. Hasn’t missed a beat yet. They replace the foot pedal the first time, made 100kms and all the lights came back on.

Just wondering if GM fixed this problem or is anyone still having this problem with the cooler lines.

I know this is a little different but I was having trouble with “service esc” “engine power reduced”. I also lost brakes with 150kms on the truck back in oct 2018. Never happened again. Now have 53990kms on it. Anyway, dealer put a new throttle position sensor in my truck, clear codes, all was good for a whopping 100kms. Back it went into shop, they replaced ecm and all has been good since the change out. Wonder if the ecm is causing these other problems too?

It’s the electronic parking brake doing a cycle
