I bought this truck in October 2019. While out on the test drive, I noticed 2 to 3 inches of free play in the steering wheel. I asked them to look into it and they found a bolt in the steering box had backed out about a half inch on it's own. They found a tsb from GM saying to use loctite on the bolt. They fixed it and everything has been good for two months. I am now starting to feel free play again and the steering itself feels very loose/ no stiffness at all when driving at any speed. I've seen many owners in many different forums complain about the same issue and I fear for my families safety when towing our heavy camper next year on vacation. GM needs to recall this issue before someone is seriously injured.

Steering is always a bit loose. At only 70,000 the ABS and stabilitrak warnings came on. Took the vehicle to the dealer and learned that the pitman shaft is backing itself out of the steering assembly. Not covered by warranty. Yet, Chevy has 6 tsbs on this issue (the latest saying to use some lock-tite on it); they had a newly designed part; and, checking inventory you learn that dealers have new steering assemblies in inventory for 2016 and 2017. Seems as though Chevy knows it has a serious safety/steering issue and have made a business decision to not recall until there is a catastrophic failure and people die. There are other reports on this site of failures at mileages from 1700 on up. This clearly is the results of a design or system flaw and is systemic. This matter needs to be investigated.

The contact owns a 2016 Chevrolet Silverado 3500. While driving 40-45 mph, the reduced engine speed warning indicator illuminated and the vehicle stalled.

At 2000 miles on my new truck, the steering became very loose. Dealer replaced steering box. I have now had it in 3 more times with loose steering. Very scarey to drive on the freeway with loose steering. You feel it more at higher speeds than you do at lower speeds

2016 Silverado 3500 equipped with "digital steering assist" this is a known problem. At approximately 11,000 miles steering became extremely loose with about 3-4 inches of free play at the steering wheel. Took to 1st dealer, steering gear box was replaced according to Chevrolet tsb and system worked as designed for approximately 3-4K miles. At that time steering again became loose but not as bad as the first time, about 1-2 inches of free play at the wheel with what feels like too much power steering, very light, dangerously light steering. Vehicle taken to dealer 2, second repair attempt dealer stated system working as designed, at this time the digital steering assist worked as it should from 0 mph to 45 mph about 1-2 inches of free play at the wheel with what feels like too much power steering with very light steering from 46-74 mph, then works as designed from 75 mph on. I went for a test drive with the service manager, he stated "I feel exactly what you are describing tight from 0-45 then light from 46-74 then tight from 75 on but the system is working as designed". in spite of this they changed steering gear box again, 3rd part, with same result. Works as it should from 0 mph to 45 mph about 1-2 inches of free play at the wheel with what feels like too much power steering, very light steering from 46-74 mph, then works as designed from 75 on. Truck is used to pull 9.000 lbs enclosed trailer. Pulling enclosed trailer at interstate speeds in winds is extremely dangerous and requires exhausting concentration and causes severe fatigue after only 150-200 miles. This is the very thing digital steering assist was supposed to eliminate. Vehicle is dangerous to drive between the speeds of 45-75, and especially dangerous while accelerating or decelerating through the 44-46 mph range while turning due to sudden change in steering pressure from system such as on/off ramps

The safety concern on this issue is the significantly elevated potential for loss of vehicular steering control. After the truck was driven to 1,700 total miles on the odometer, the truck's steering control became sloppy in 70mph + interstate highway driving resulting in highway wander similar to driving in wind gusts of 60 mpg+ (where at times it is difficult to maintain position in your highway lane). Subsequent examination of the steering box showed that the steering gear pitman arm lash adjustment screw on the steering box had backed off approximately 3/8", the steering had excessive play and the steering box was leaking power steering fluid. The steering system on this truck is a digital steering assist system. The truck was returned to the dealer and unsuccessfully (no change in functionality) repaired under GM tsb #pit5501C (replacement of the steering box) and subsequently successfully repaired (to date) under GM tsb #pit5501D (replacement of the steering gear pitman arm shaft with an updated design GM P/N 84240812. Currently have approximately 5,500 total odometer miles on the truck.

New truck had lose steering when I took delivery, requiring over correction. With just 4529 in mileage on it I took it back to my dealer. Was told they already had made repairs to four other trucks with the same issue. They replaced the hydraulic recirculating ball steering gear. Steering gear adjuster way too far out, leaking at shaft seals. Replaced gear and the new one was bad as well, with steering sticking and then slipping. Replaced with second new gear and vehicle checked out and was returned to me. This is a major safety issue in my opinion for a truck designed to tow heavy vehicles.

I purchased a 2016 Silverado 1500 4WD ltz crew on February 08, 2016. On February 20, 2016 with just 312 new miles driven on the new vehicle, the electric power steering stopped working while driving 60 miles per hour going West on the southern state parkway middle lane in nassau county New York. With no power steering on a six thousand pound truck, I had to struggle with turning the steering wheel away from other vehicle on the parkway and exit the parkway without causing an accident. I immediately call for road side serviced and the truck was towed and return to the dealer for service. During the investigation, the Chevrolet service department located in valley stream, NY stated on February 24, 2016 that the entire electric rack opinion for the power steering was defected when it was installed during the assembly by the manufacture. The 2016 Silverado 1500 truck was purchased new on 2/08/2016, and I have concerns that other mechanical parts in the vehicle may be defected and the vehicle may be unsafe to drive.
