2013 Chevy Avalanche… Check engine light came on when driving - codes: P069, B2AAA, P0700, U0073 - all at once. Truck slowed down, transmission stuck in 2nd/3rd only - was able to reset the check engine light. Seems like an unspecific problem, but something like a sensor issue causing this - I see a Jan 2015 Recall Notice on the USDOT site - indicating there may be a bad Chassis Electronic Control Module due to contamination — any thoughts on this? Haven’t taken any action yet - thought I’d drive it for 4 days or so and see if it returns… but also thinking of having it checked by dealer. Thanks.
Well, print out the recall notice. Check with your dealer to find out if your vehicle has been corrected.
You did not state purchase date and mileage. Vehicle MIGHT still be under warranty.
