NHTSA Complaint #11718112 — 2023 CHEVROLET SILVERADO 1500

My 2023 Silverado 1500 6.2L ZR2 AEV with 17,500 miles went into the shop for the L87 Loss of Propulsion recall, on 20 OCT 2025. The dealership didnt contact me for 2 weeks, so I called. They than told me my truck failed the pico test and needed a new engine. I also asked for my leaf springs to be looked at under tsb for excessive noise. I also asked for my ZR2 to have the new update installed for the radio fix (my speakers crackle when I talk to people on bluetooth). They had my truck from 20 OCT 2026 until 27 JAN 2026 for a total of 99 days straight. No loaner was available. I had to call GM customer service every week for subpar updates from the dealership. Im active duty army so not having my pov to report to work was very stressful. When I got my truck back, it was covered in dirt, oil on the exterior paint and inside the engine bay. The dealership didnt update my truck as requested and didnt touch my leaf springs at all. They said it would take 5-7 weeks to get new ones, but I needed my vehicle back which is anitated on the work order. Thr parts were all delivered 45 days after it sat there and my truck wasn't worked on until day 94 as advised by the service advisor, as the mechanic would get to it after his next vehicle. I asked how is my truck not priority sitting there for 93 days at the time. GM customer service has submitted my vehicle payment reimbursement as I paid 4 payments while having no vehicle or loaner. $44 a day for a rental at my duty station would cost me considerable amount of my own money to cover the rest and would not be a similar vehicle to my truck, as ot would be a small car. JN Chevrolet in Honolulu did not communicate when it failed the test for 14 days, I had to call them, they gave zero updates for 2 months, I had to call GM customer service. I only received 4 calls in total from the dealership when I asked to speak to the manager. (Who never called me back). I got my truck back filthy, other services ignored. 3rd Silverado and last.
