I have a 2014 4runner Trail that I just had the UCA's replaced on. Before dropping off the car I installed the Anytime-Backup Camera which included some minor wiring.

On the way back from picking up the truck (2-minute drive) the car died as I was making a turn. I thought this may have had something to do with my wiring so I went over all the grounds and connections and tightened/secured everything. Next day on the way to work my car died backing out of driveway as I was making a sharp turn. Car started right up so I went to work. The next morning the car died again after leaving a parking space and turning onto the exit. The engine stalls and the lights on the dashboard come on. I stopped taking other people in my car because of this, and have altered my route to work.

I did some research and this seems to align with the fuel pump issue. So i dialed corporate who gave me a case number and said the local dealer would be reaching out that same day. They emphasized this was a huge safety issue and said the dealer would provide me with a suitable truck since I use my 4runner to visit construction sites and occasionally deliver material. 2 days pass and I let corporate know the dealer has not reached out. They say they notified the dealer and they will reach out the same day, all under the same case number. No word from the local dealer. It's been about 5 days and I have not heard back from corporate or the local dealer.

What is the best course of action to take?
