Question type: Maintenance & Repair

Son drove car to base in nc from pa. Just outside base car shuts down but starts within will not accelerate,goes like 1-3mph. I assume limp mode.tow car home in pa
and read codes, starts are p2534,p0700,u0073. What should look
for/at next.

The P2534 code is for the ignition switch. The P0700 and U0073 codes are for the transmission control module and the transmission control module not getting power (bus). I'd replace the ignition switch then clear the computer. If that doesn't solve the problem you'll need to take it to a transmission shop for further diagnosis. HTH. -Jim

Did you ever solve this? My 08' Equinox sport has these exact 3 codes and has the same transmission and engine.
