Service Airbag light is on. Airbag removed and replaced at owner's expense. Diagnosed electrical concern. Cost Not covered by GMC. There has been four Airbag recalls on the 2016 GMC Sierra since 2016, but none covering total replacement of the Airbag. Recalls dated 09-08-2016, 07-10-2017, 11-25-2020, and 07-01-2021. Does NOT seem logical to me to cover cost for most of the component, but not the Airbag itself. This doesn't seem fair...$1422.45.

At low/idle speeds the brake pedal becomes hard and will not stop. At speeds between 35-75mph the engine/transmission has a vibration about every 10seconds and the transmission shifts hard and/or rough at times when first taking off.

Took my truck to gmc dealership to get brakes and transmission fluids flushed, then a few months later I noticed that my truck started shifting hard. then one day going back home from work I lost 6th and 5th gear, would not go into either one. then I lost all gears and would just red line when I pressed the gas. had to coast into a parking lot to get a tow truck and carry it to a transmission shop. the shop said that the universal clutch was burned up and would now cost me $5,000 to fix.

At low speed (5 mph or less), my GMC truck looses brake pedal resistance and I have to mash the pedal hard to stop.... very dangerous when in traffic, parking lot or pedestrians crossing in front. This needs immediate attention. No warning lights on dash. After researching this issue online I discover there are many youtubes and complaints about this apparent brake vacuum pump problem). I also see where there is a recall of over 3.5 million Chevy/GMC vehicles (recall #s N202300860 and N192268490) for this exact low speed brake pump problem. My GMC truck falls within this recall (GMC Sierra LD between 2014 and 2018). But when I check my VIN # on the NHTSA website, it states no recall. How can this be? It clearly is the exact same issue. Please explain.

My 2016 GMC Sierra 1500 (5.3L 8-speed). When on the highway or in the city when the truck is changing gears it has a shake almost like hitting small bumps on the side of the road. I have several friends and family members with the same model truck and have spent thousands of dollars to fix the problem by modifying the whole truck. Is there anyway a recall could be made since it has to be a huge issue with all models with the v4 mode? I brought it to a transmission shop due to GMC dealerships being booked for weeks..the receipt is attached! They said the fluid was burnt and changed it but need new torque converter!

Just purchased this used vehicle in December 2022 with high miles (202000) with a dealers extended warranty. Problem has happened twice in 2 weeks. While backing up slowly and turning my wheel the vehicle stalled and Service Stabilitrak came across the dash as it died. Then upon restarting it told me to roll drivers window down and up and the memory seat function cleared as did my clock. Like it had a battery replacement and reset to factory. Took into a GMC service shop where they found code P0700 and P0711. They were able to replicate my concern. Telling me to replace the transmission harnesses and that it is not covered under my extended warranty for powertrain. Going to cost me $1500 in repairs. After extensive research I see this is a common problem yet no recall has been issued for my 2016 GMC Sierra crew cab. Very frustrating!!

Was in a parking lot, moving just 2mph and had to literally mash down on the brake pedal - both forward and backward. Also, I put my truck in drive and has been making a noise in the transmission it seems and is a loud + lurches forward a bit. Additionally, I was traveling on vacation to Rockport, TX. I've made a appointment with the dealership here at 10:00 A.M. on 9 Dec 22, it's the earliest I can get my truck in. There was previously a brake issue covered under warranty & should be again!
