The Infotainment center display is black and therefore unable to utilize backup camera. The screen is still sensitive to touch but does not display anything for any function. Primarily a safety risk for backing up a large vehicle.

ENGINE
Currently own a 2018 Chevy Suburban with a lifter issue in the engine. This is a known issue with Chevy as many vehicles have experienced this problem from zero to over 100k miles. Chevy has not issued any help or support with customers with this issue. My vehicle is well maintained I get oil changes frequently and have never not done a required service when needed. When I notice an issue I immediately take it to in Regal Chevy for repairs and no matter what the issue is I get it repaired on the spot. I find it odd that this is a recurring issue and Chevy has done nothing to help support loyal customers.

WHEELS
Rim corrosion resulting in loss of air pressure. The inner portion of the rim is corroding causing the tires to loose pressure. Depending on the amount of corrosion this could lead to a catastrophic failure at some point due to sudden loss of pressure. I took my vehicle to a tire shop thinking there was a puncture causing it to loose pressure. The manager explained to me that the pressure loss was due to corrosion of the alloy rim and that it is common with Chevrolet vehicles with factory alloy rims. The only solution to the problem is to have the rims possibly refurbished or replaced.

ENGINE
Car abruptly lost power while driving causing rapid deceleration and requiring immediate action to steer vehicle off the active roadway without hitting other vehicles or causing property damage. There were no warning lights or signs until this occured. The vehicle was later towed to chevrolet who informed us that this was a KNOWN ISSUE these cars have where their "lifters fail and sometimes even damage the camshafts" If this was a known issue why would it not have been addressed in a recall. After speaking with the dealer I searched the internet for the same issue and it is widespread across several GM cars including mine. GM now wants $3,100 to repair a dangerous manufacturer defect.

ELECTRICAL SYSTEM, ENGINE, STEERING
While slowing down to make a left hand turn at an intersection, my vehicle suddenly lost power steering and the entire system completely shut down. There was no electronic function during that time. I had to put the vehicle in park, turn the key to the off position and then start it back up. It has happened multiple times, both at low speeds in drive and reverse. This would have caused a collision if there was oncoming traffic at the intersection at that time.

POWER TRAIN
On two occasions, most recently on 6/13/23 the vehicle went from 70 mph to 10 mph very suddenly on an Interstate in heavy traffic--very dangerous. The display indicates an over-heated transmission but the dealer believes its some electrical problem. This 2018 Suburban has an 8 speed auto transmission which has a lot of on line complaints and lawsuit pending.

ELECTRICAL SYSTEM
While driving the vehicle lost all power and after about 20 seconds power came back on. The repair was the battery cables which was apparently very common on the make and model of vehicle. It's unsafe and can cause an accident and apparently happens on the majority of vehicles same year and make.
