When I taught at university I believed that requiring students to write papers on finance and economics allowed them to develop a deeper understanding of the topic. This applied to my own research as well.

Upon reading Arnold’s piece I was led to wonder how the junior partners will develop that depth of understanding if they have relied upon AI to do their research.

Just yesterday I posed the following question to Grok:

"My 2013 Kia Sorrento was sitting parked for 5 hours. When I turned it on, the engine check light came on for the first time and the OBD codes showed P0711 and P0713 code warnings. Later, the light went out without me doing anything to the car. What is the most likely problem with my Kia Sorrento?"

This was Grok's reply- one I had already figured out after about 2 hours of web search and reading:

"The P0711 and P0713 codes both point to issues with the transmission fluid temperature (TFT) sensor circuit in your 2013 Kia Sorento—specifically, range/performance problems (P0711) and high input signals (P0713).

This is a common issue on Sorentos from this era, often triggering on cold starts (like after sitting for several hours) due to erratic sensor readings when the transmission is cold, which aligns with your description.

The check engine light going out on its own suggests an intermittent fault that may resolve as the vehicle warms up, but it could return, especially in colder conditions.The most likely cause is a failing TFT sensor itself, which Kia has addressed in technical service bulletins (TSBs) for similar models and symptoms, recommending replacement of the sensor (often integrated with the internal wiring harness).

Less common but possible related factors include wiring harness damage, poor connections, or even low/contaminated transmission fluid contributing to sensor misreads.

If you notice symptoms like hard or erratic shifting (particularly when cold), that would further support this.I recommend having a mechanic or Kia dealer scan for any recurring codes and inspect/replace the TFT sensor if needed—it's located inside the transmission (requiring pan removal and fluid drain/refill), so it's not a DIY for most people.

Check if your vehicle qualifies for any extended warranty or TSB coverage, as this has been a frequent repair on 2011-2013 Sorentos. "

The dealership's tech guys first impression was 'Don't have any idea what the problem is, could you leave the car with us for a day or two."
