When transiting between airport and home in very remote area in subzero temps the DEF warning system suddenly came on limiting vehicle speed progressively. No services were available both at this time of day and in this very remote area. There needs to be some way to override this system in the case of potential life and death. There were no warnings that this system was going to activate, it simply came on. The system had plenty of fluid but it appears the DEF heater failed. A vehicle should have an override for life and safety matters. Vehicle is going to a diesel mechanic for service now.

All fuel injectors in "bank 1" became faulty and need replacing immediately with little to no warning of issues. Check engine light came on after multiple injectors became faulty. Check engine light came on while traveling on a straight road after 2 minutes of highway travel going 70 mph. Consumer stated I'd like to add the following information to my report. After looking further on the NHTSA website, I came across information in the 'manufacturer communications' section of the website pertaining to 2017 Chevrolet Silverado 1500's. the NHTSA id number is 10163854, and manufacturer communication number is N182198000. In this letter it explains issues with bank 1 fuel injectors, and what I experienced with my pickup. Under the 'conditions' section of this letter, page 1, my vehicle meets all the conditions aside from living in Wyoming and not one of the 13 states listed. My pickup is a 2017 Chevrolet Silverado with a 5.3L engine, the malfunction indicator lamp illuminated, I took my vehicle to garvin motors in powell, wy, and they said a diagnostic trouble code returned with fuel to air ratio issue in bank 1. upon further diagnostics it was reviled the fuel injectors need replacing in bank 1, just as stated in this letter from GM. I have been in contact with two GM dealers in the area, and I have been quoted two prices to replace parts listed on this document from GM. I have also reached out to GM, and they said they will research this letter more and get back with me. I am now two weeks without a vehicle while the dealership is demanding I make a decision to have repairs done, how I will be able to pay for repairs upon completion, and GM customer support will not take my calls with telling me they will be called back. I have spoken to GM three times about this with each time stating they need to look into the matter further. Denny menholt dealership located in cody, wy, currently has my pickup with no repairs started at this time.

My 2017 siverado with less than 50,000 miles is at the dealership, due to a defective fuel injector on the #7 cylinder. I am being told it is not under warranty, and that I will have to bare the cost of the repair. I do not feel that on a two year old vehicle, that the fuel injector should fail, nor should I bare the cost of replacement. I am not asking for a resolution, I just want other to be aware of the defect.

Engine hesitation, or misfiring. Jerking, or transmission shuttering when engine is at low RPM and on incline. (I.e. when traveling about 45mph and start up a hill, the RPM's are about 1300, and the transmission doesn't gear down, so it starts shuttering until you give it more acceleration than usual.) after dealing with this issue for nearly 8 months and 15K miles, I believe this safety issue should be recalled. Dealer originally acknowledge the problem but was unsure of the cause. After 5 repair attempts the dealer say they can't duplicate and the vehicle performs as designed.

Vehicle hesitation and surges in acceleration. This condition is a safety issue as it hesitates pulling into traffic, surges in acceleration have caused loss of tire traction on ice covered roadways nearly resulting in a collision. Dealers have acknowledged an issue but advise they are still waiting on a fix from GM.
