I’ve got a 2019 GMC Sierra 2500 with 42k miles on it that has just been chewing through sensors recently. It’s been in the shop 3 times now for that same sensor (fuel rail pressure sensor on passenger side). GM has advised me to have the entire engine harness replaced which will run me about $5500. Has anyone ran into this before? Truck is fully stock. No problems when purchased in November 2019.
