general problems of the 2016 GMC Yukon

My wife was driving down the highway and out of no where there was a loud taping sound, the vehicle started running real bad (skipping), the vehicle lost power and she lost control of the steering. As a result, she ran off the road into a ditch. This is a known concern with the 6. 2 liter engines and all signs are pointing to lifter failure. She could have ben seriously injured and gm is responsible for this.

We first noticed the vehicle's lack of power and sudden increase when driving at a stop light/sign. We checked and replaced spark plugs, cables, coils, and a new battery. We became highly concerned when the vehicle would accelerate while driving and the rpms would toggle between 500-1500 rpms without pressing the gas. We immediately took it to an authorized mechanic, who found excessive noise from the transmission area and found debris/metal. No codes were present when a system performance was done. The vehicle only has 68806 miles on the odometer. The transmission had to be fully replaced, which cost over $7k. The replacement was done. This seems to be a common issue (transmission replacements) with this vehicle as now we're hearing more about it. Please check this as we could have easily been in an accident from the loss or increase of power without notice and no warning lamp indications. This was a very expensive repair caused by the manufacture and not user error. We paid a lot for this particular vehicle and certainly love it but am concerned about this expensive safey/mechanical issue. Please call me for any questions (napoleon erazo 972-740-8783).

When I was merging on the fwy my car accelerated and I couldn’t slow it down. I had to get off the fwy and break really hard. Driving on the fwy and not being able to control the speed or breaks could of caused an accident or cost us our lives. I have an appointment with the dealer service center on sept 20, 2022. A few weeks ago I noticed the car was having trouble sifting gears.

My 2016 GMC Yukon sle vibrates really bad on high speeds starts from 70mph and up I took it to do a wheel balance and the problem is still there also I check the VIN for any recalls and nothing I search and I have seen that all chevy tahoes Cadillac escalade GMC Yukon have the same problem and they havent fix it. Does any one knows how to fix it or if theres gonna be any recall on the problem. . Thank you.

We have had our 2016 Yukon xl for almost 2 years. Last year we started experiencing episodes where the vehicle will shift down into reduced power mode with p0090 and p0091 as the fault codes. We have been working with the dealer, but once the vehicle has been turned off for about 20 minutes or so it clears and leaves no trace of an issue. This is extremely dangerous and recently shifted into reduced power leaving us only able to drive 35 miles per hour. We were on the highway in maryland with cars flying around us at ~80 miles per hour. We had all of our children in the car and were in the far left lane. The reduced power made it nearly impossible to get to the right shoulder safely. I have a friend with a new GMC sierra that has the same issue. He dropped it off at his dealer for 3 weeks and returned it finding any issues. This is very dangerous and needs to be addressed. All it will take is someone dying to turn it into a class action lawsuit.

1. Loss of braking function and could not stop vehicle, loss of control of vehicle on highway and street at speeds of 70 mph. Brake vacuum pump was confirmed defective at dealership 10/17/18. 2. After repair by dealerships brakes did not function correct again, confirmed and stated on dealership invoice 6/28/19 same part number was defective again, dealership that conducted repair on 10/17/19 repaired defective brake with the same defective part. There was another brake issue with the braking system in February as well. 3 brake issues under 1 year and repeat defective part used in dealership for repair. Multiple dates below but 10/17/19 specifies date confirmed at gm dealership ed rinke.

I have had issues with the transmission and power of the car for over two years. I have contacted GMC and have followed everything that GMC have requested for me to do with a vehicle. I have taken the car to four different dealerships, have had everything done with it from flushing it three to four times and have had torque converter replaced the control valve body replace. Recall for the brake pedal was also done. After everything the car is in worst condition at the moment.
