Vehicle stalled out in very heavy traffic in both Maryland, and Indiana while I was on vacation. This occurred on a major highway in both occasions that was packed with traffic.this incident could have easily resulted in a major accident that could have been harmful to both me and my family. This incident happened on 2 occasions, July 16th 2016 and July 22nd 2016.dealership at first could not find the problem as was the case with the first Cadillac dealership in bethesda Maryland. The 2nd dealership took a week to create, identify, and hopefully repair the problem. Replacing fuel pump ended up being the call. $1005 dollars later I certainly hope that this fixed the problem. This indeed is a huge safety concern as it does not show any warnings it just stalled out.

After driving the car on highway with no issues car will stall out approaching lights, stop signs or slowing down or letting off gas pedal.has happened 8-9 times in last week. No warning lights or idling issues that would warn us of the issue. Changed battery, crankshaft sensor, cleaned throttle body, fuel filter, and changed oil. No codes show up on mechanics diagnostic meter.I have taken to online Cadillac forums and learned this is not an uncommon problem.very unsettling with wife and 4 children in vehicle.

I was driving approximately 60 mph, when my dash warning sign began to read "low oil pressure- shut off engine" and began beeping incessantly. As I was on a bridge/expressway, I was not in a position where I could safely stop the engine. The engine went into "limp mode" and was struggling to maintain power.
