While taking my children to school, the vehicles RPMs began to jump, causing the vehicle to lose power. Which resulted in myself and two children stranded on the side of the road. The vehicle had just crossed over 110,000 miles when the transmission completely broke apart from the inside. There was no other warnings or lights that appeared on the dash prior to or after. We had been given an estimate from GM for $6200 for a new transmission.. but that was extremely difficult to afford. We ultimately had to have the transmission rebuilt due to it costing $3,000 less, so we could continue going to work. We are still having issues with the transmission even after taking to back for a 2nd time to be reprogrammed. It’s extremely frustrating to have paid so much for this Yukon to have transmission go out with as many miles as it did, plus with no warnings.

I lost my power steering ability in the steering wheel and I observed my power steering service light indicator warning come on. I pulled my vehicle to the side of the road and turned off my vehicle. I started the engine with no change in the steering mechanism. After twenty minutes passed, I restarted the engine. I was able to drive with normal power steering conditions. On [XXX], while driving my Denali, I lost power steering maneuverability while driving.
