Incident Report Vehicle Information: Year: 2016 Make: Chevrolet Model: Suburban I am experiencing a recurring issue with my 2016 Chevrolet Suburban involving the steering column lock module and the theft deterrent system. The truck intermittently fails to start, displaying a "Theft Deterrent" warning message on the dashboard and lighting get dim on the display. On some occasions, after waiting approximately 10 minutes, the vehicle starts, but other times it does not. Additionally, there are instances when the truck starts but cannot be shifted into gear. To address the problem, I have attempted to disconnect and reconnect the battery to reset the system, but this has not resolved the issue. The problem appears randomly and unpredictably, creating significant inconvenience and safety concerns, particularly in situations where I am stranded or unable to move the vehicle. Impact on Safety: This issue poses a risk to my safety and the safety of others. The inability to reliably start or move the vehicle could lead to dangerous situations, especially in emergencies or high-traffic areas. It is also concerning that the theft deterrent system may be malfunctioning, potentially leaving the vehicle vulnerable to unauthorized access. Resolution Attempts: Despite attempting to reset the system by disconnecting the battery, the issue persists. Online forums and anecdotal evidence suggest that this may be a common problem with the steering column lock module or related systems in this model. Request for Action: I urge the NHTSA to investigate this issue as it appears to affect multiple owners of similar vehicles. A thorough review and possible recall or service bulletin could ensure the safety and reliability of affected vehicles.

At low speeds while steering, the steering wheel locks up for 1 or 2 seconds causing the vehicle to drive in an unintended direction. This is sometimes accompanied by the electrical system rebooting, and sometimes, there is no warnings at all. It has happened to us 4 times in the last six months. The dealer has had the car twice and is unable to reproduce or diagnose. In addition, sometimes the car has rebooted while driving 60 mph on highways. When this happens, it has engaged cruise control at least three times. I don't view this as unsafe as the steering description given above.

Reduced or loss of power steering assist. Steering wheel jerks or kicks back when turning. Service Stabilitrak message with warning chime. Engine stall. IPC going blank or inoperative. Radio/ICS going blank. HVAC going blank. Hood ajar message and/or dome lamps flash when shifting into reverse. Alarm sounds when locking doors or door locks cycling. Wipers continue to run for a short time after turning off and then stop/park in the incorrect location Engine stall and loss of steering almost caused a collision putting mine and others lives at risk. This has happened seven times since I bought the car in July 2021. No warning its going to happen other than dash lights flicker, warning lights on, steering fails, car dies, won't restart. GM has a Technical Service Bulletin #18-NA-161. I hope you can do something about this serious problem before someone is serious hurt or dies. Thank you

The brake pedal was stiff requiring extra effort than normal for the vehicle to come to a stop. While turning left or right at low speeds, the steering wheel was difficult to turn and made an abnormal hissing sound. The contact stated that there was oil leaking from the front-end of the vehicle. The contact took the vehicle to the dealer who diagnosed that the vacuum pump failed and needed to be replaced.

This has happened at least 10 different times within a month. First time I was parked and when I went to put the vehicle in drive, I tried to turn steering wheel and it seemed to lock up and all the lights started to flicker. After about a second it allowed me to use steering wheel. This seems to happen at a very slow speed. When I drive through at restaraunts, the steering wheel locks up. The radio will quit playing. If I turn off the vehicle and restart it the radio will work once again. When the vehicle does this, none of the turning signals work.

My truck turned off all light in the vehicle for 1 second affecting the steering wheel. I wasn't able to make the turn that was coming in front of me luckily was only 1 second that this happened then all power came back. Got out of the freeway right away. This experience was really terrible for our family and I. the motor never when off only electrical on the truck. By the way we were driving 70mph on the freeway when this happened.

Power steering completely failed same as in 2015. My wife could not steer the vehicle. After leaving a parking spot driving down street my wife was not strong enough to turn the wheel. Power steering failure appeared on the dash, she ended up on a neighbor's lawn. Chevy would only cover a portion. $2000 my cost to fix for a part Chevy knows if faulty. Vehicle has 50000 miles. Just thankful my wife and three kids were not on the highway when this happened.

At times, the entire electrical system fails while the vehicle is operating. Typically, it quickly reboots, but at times will not restart for several minutes. This has happened while making a hard turn at low speed, in which the power steering fails, wheel jerks, and entire electrical system and engine become disabled, and has also happened at highway speed while operating on cruise control, with the electrical system typically shutting down when the blinker is engaged to change lanes. When electrical shuts down, results in complete loss of all electrical systems including power steering, brake assist, engine power, lights, etc.

While driving my vehicle with my children inside I happen to experience probably the worst experience while driving. I got a error message on my screen "power steering drive with care" at 50 mph. I almost caused an accident with this. This is a huge safety concern. Problem started at 37,500 miles. I have been reading complaints and recalls and they all state 2015S and below with this problem. This issue is across all vehicles in the Chevy lineup. Found a video on youtube to see if it were a simple fix and it did "fix" temporarily". problem came back even worse. Took vehicle to dealer and I am out of warranty and they want $2500 for the part (elec. Power steering pump & installation). There are no error codes dtc showing when plugged to obd port. Looking for a resolution from the manufacturer as this is a huge concern and for my family.

I constantly have to turn the steering wheel (adjusting) from side to side in order to maintain a straight direction, even when the road is straight. It is especially necessary when driving on highways. The only time I don't have to constantly correct the steering is when there is a constant side wind from one side. It is as if I'm driving a high mileage vehicle with worn steering components. The issue has persisted from day one when the vehicle was bought new. This is my fourth Suburban, and the first time I have this issue. I have been informed that the first three Suburban's had hydraulic P/S; and that this Suburban has electronic P/S. I have complained to the dealership multiple times, and been told there is nothing they can do about it. I have also reported it to GM under case number 8-3065886402.
