NHTSA Complaint #11716169 — 2019 CHEVROLET SILVERADO 1500

"Approximately four months ago, I noticed an oil leak coming from the midsection of the engine/transmission of my 2019 Chevy Silverado LTZ with the 6.2-liter engine. At the same time, I noticed a slight knocking or rattling noise coming from, I believe, the front of the engine. Upon taking it to the dealership, they replaced the engine oil coolant lines, only to find out that the engine was still leaking oil and still making the knocking and rattling noise. They then discovering that it was the rear main seal, they have since replaced it about one week ago. Yesterday, February 6th, about 12:15 pm in the afternoon, while I was getting off the I-405 in Renton Washington and merging onto the southbound lanes of 167. I was in the left lane and I made it about a quarter mile down 167 doing about 60 to 65 miles per hour and I lost power suddenly. As I started to merge into the right lane, I noticed the engine light came on, and then the truck seemed to kick down into first gear while I was doing 50 miles per hour, which instantly slowed it down. This forced me to cross over an on-ramp lane to get to the shoulder and come to a complete stop. After that, the truck would not start at all. I then had to sit on the side of the road for three and a half hours waiting for a tow truck to take me and my truck back to the dealership, which is also the same dealership where I bought the truck back in 2019. They have not diagnosed it yet as I just dropped it off at 4 pm on 2/5/2026. My truck has approximately 155,000 miles on it.
