I was driving down the highway when my vehicle loss control of operation and check engine light came on. After taking it to the GMC dealership it was determined to be a bad lifter in the motor. The garage had to take the motor completely apart to repair a bent rod and cylinder in the motor. There are numerous reports and a pending class action lawsuit concerning this device in the GMC sierra trucks and other GMC vehicles. The lifters in the cylinder of this motor are designed to switch the engine from v4 to v6 to save on gasoline. My vehicle has been repaired by the GMC garage but I've seen reports of this problem repeatedly happening in these vehicles and it causes me great concern because if there is a lot of traffic in the area I could get hit or cause an accident by not being able to operate the truck. My vehicle is available for inspection upon request. The safety of myself and others is put at risk because the sudden equipment breakdown could cause an accident. The problem was confirmed by the dealer. No other parties have inspected the vehicle. No warning lamps went off prior to this happening and the vehicle is only a 2018 and only has 36,000 miles on it.

The electric power steering failed while accelerating into a turn from a stop at an intersection. The wheel was jerked from my hands, and the engine stalled, all electrical failed momentarily. Within a couple of seconds everything returned to normal. This has happened several times since I purchased this vehicle. Also the electrical power steering drops out quite often at low speeds, such as in parking lots. No warnings have ever been given. In may of 2021 the dealer replaced the steering rack, the problem has continued intermittently to this date. I have researched for recalls on this problem and found that GMC issued a recall for years 2014-2017, and am amazed that they could just declare the problem fixed, and leave such a dangerous problem unresolved!.

No transmission power regardless of the gear shifter position. I turned the engine on and off several times trying to get a solution, no luck. I returned to the vehicle 5 minutes later and did get it to move,,,would only go 25 mph at 3000 rpms. I was in the middle of WI not near any major dealership on-star was useless saying I had a major engine problem and the computer was trying to protect the engine. I was directed me to a Chrysler dealer ship, who told they could not get me in for 2 weeks, suggested another branch which was over 45 miles away. I drove 5 miles to a friends house and was able to find a dealership in janesville, WI (fagan). When I started the vehicle to drive to janesville, the transmission did work. Fagan spent 2 hours working on it, and could not find a cause for the problems, they checked every computer, could not duplicate what happened. They reprogrammed all the computers. Then in cincinnati, OH the power steering assist went "off", while staionary. I tried restarting several times to no avail, drove the 3 miles left to the g'kids house, no power steering, trailer problem lighjt on, no rpm or mph needles moving. Called local dealership (borcharding) and they suggested I drive it to their location 12 miles away. When I started it, the power steering was back on, but the unit would not get out of 2nd gear, ran 40 mph at 2500 rpm, warning lights all on, engine light still on. Next moring I started the vehicle, everything was okay including the transmission problem, but still had the "check engine on", the dealership kept it (2) days, involved GMC engineers, could not determine the cause for all the problems,including loss of "steering assist". They drove it over 50 miles on two trips,could not duplicate what happened. They told me it was some kind of computer problem, but could not determine, they reset everything again.
