At 64,497 my wife's power steering went out on her vehicle. This happened a day after our trip to atlanta, GA. We took it to our local GMC dealership and was notified that 4 modules had to be replaced and a recommended wiring harness. In 2015 GMC vehicles had a similar issue and recall but not the 2016. This cost me $1400 in repairs.
The rear tail light is not working properly. Around December 17, 2018 I was driving my vehicle on the city street and highway when several people advise me my light was out and not working. I check it once arrived at home and it was working properly and didn't problem. And a week later same issue from people pulling me over to advise me my tail light was out. Around January 10, 2019, I went in to hutchinson auto mall GMC dealer and they advise me everything is working properly and doesn't see a problem, and advise me to bring back should I experience the outage again. I inspect vehicle as well and seem no problem. 23 January 19 same problem and went back to dealer and they discover the outage and advise me the led tail light strip was out and need to replace the assembly. It appears their seem to be a wiring issue where the light is and out. To keep from a serious problem or fire. Request immediately investigation. The technician also advise me this seems to be a common problem.
