2020 CHEVROLET SUBURBAN Complaints

When putting vehicle in reverse, the screen for the rear camera will go to full intensity brightness. There is no adjustment for this, as the dashboard lights do not control the screen brightness. It is impossible to see out of the Sideview mirrors with the windows up due to the reflection off of the windows. This is amplified even worse when it is raining at night. GM had a recall for this problem on the previous generation Suburban, and it was corrected by a software update. I have had it at the dealer twice since buying it in June. They have confirmed the issue, but state that GM says this is normal. You shouldn't need to roll down windows at night in order to see out of your mirrors. When the vehicle is taken out of reverse, the camera will dim down to an appropriate brightness, but that is when the vehicle is in Drive, and the screen returns to normal layout. There are numerous complaints on this specific generation vehicle on multiple forums across the web.

My car shut off two times while driving. When you google the issue, it auto populates meaning that this is a very common issue with GM. It starts back to 2015 searches as well. GM needs to recall their suburbans for their cars turning off while driving which caused me to lose power steering, power brakes and anything that requires electrical.

Total Brake failure without warning, DTC, or messages. Coming out of a parking lot applied the brakes and the brake pedal went to the floor and was not able to stop. I tried pumping the brakes which pedal to return to the correct position but went back down to the floor. Had the vehicle towed to the dealer which confirmed the truck needed a new master cylinder, brake booster, and vacuum pump.

The contact owns a 2020 Chevrolet Suburban. The contact stated that while operating the vehicle a banging noise was present coming from the engine compartment. Additionally, while driving, the cluster gauges and the air conditioning malfunctioned. The vehicle was later examined by an independent mechanic who diagnosed that the water pump had failed. The vehicle was towed to the local dealer but not repaired. The manufacturer was not notified of the failure. The failure mileage was 30,000.

Have had starter problems since we purchased the vehicle. Starter intermittently loudly grinds when pressed 2-3 times a week and won’t start. Dealership could repeat problem once, but never fixed it. Took vehicle in at least half a dozen times. Never fixed. Car also makes an odd humming when gas is applied. This week, car started and died after driving a foot. Then car wouldn’t start at all. Brakes stiffened up and wouldn’t compress without substantial effort. Everything resolved on its own within 30 minutes. But the very next day, pulled inti position in our alley to back our Suburban into the garage. Put car in reverse. While using the back up cam (that came on like normal when car is in reverse), i applied gas. The car didn’t respond at all (didn’t even rev like what happens when you apply gas while car is in neutral). I applied a touch more gas and car all of a sudden lurched forward with the full force of a V8 engine being floored. I tried to slam on the brakes, but the brakes wouldn’t respond in such a way that i thought my shoe must have gotten stuck. It hadn’t. The brakes did not work. I don’t know how long it would have taken to finally stop because we only had 5 feet to go before we slammed into our neighbor’s house (which is what stopped our vehicle). Car is not drivable and I wouldn’t drive it if it were. It is available for inspection. Will be towed once scheduled.

While turning at driving speed I feel as if I loose control of the steering for a split second. The front wheels feel like they begin to turn without me turning the steering wheel. This has happened at least a dozen times in the 6000 miles I have put on the car. It is extremely dangerous especially on wet roads. I have not reported this to GM. I was searching the internet for a recall and found your website.

2020 CHEVY SUBURBAN LESS THAN 5,000 MILES ON MICHELIN ENERGY SAVER A/S 265/65R18--APPEARS A BULGE CAUSED A TRIANGLE SIZE CRACK EXPOSING SIDEWALL. THE VEHICLE HAS NEVER TOWED, OR BEEN OFF ROAD AND IS STORED IN GARAGE

INTERMITTENTLY, WHILE ACCELERATING, A JOLT IS FELT EMANATING FROM THE RIGHT HAD SIDE, POSSIBLY TOWARD THE FRONT OF THE VEHICLE, WHEN THE AUTO FEATURE OF THE 4 WHEEL DRIVE IS ENGAGED. THIS OCCURS AT SPEEDS OVER 50. WHAT IS DESCRIBED IS AN ONGOING PROBLEM, SINCE THE VEHICLE HAS BEEN PURCHASED.

WHEN ADAPTIVE CRUISE IS ENGAGED, THE SYSTEM HESITATES WHEN LEAD VEHICLES SLOWS AT A SLOW RATE (NO BRAKE LIGHTS OBSERVED ON LEAD VEHICLE), REQUIRING OPERATOR TO APPLY BRAKES. WHEN ADAPTIVE CRUISE CONTROL IS ENGAGED DURING HIGHWAY DRIVING, INTERMITTENTLY, MEDIUM SLOWING OF LEAD VEHICLE (BRAKES APPLIED) THE VEHICLE DOES NOT REACT IN TIME TO AVOID COLLISION WITHOUT ACTIVE AND HEAVY BRAKE APPLICATION (JERKING DRIVER AND/OR PASSENGER) TO AVOID COLLISION. ABOVE 65 MILES AN HOUR THE ADAPTIVE CRUISE CONTROL DOES NOT LEAVE ADEQUATE DISTANCE BETWEEN VEHICLE AND LEAD VEHICLE. I FIRST NOTICED THIS IMMEDIATELY UPON FIRST LONG DISTANCE DRIVE. THIS IS AN ONGOING PROBLEM. HAPPENING FREQUENTLY BETWEEN JULY 4TH AND JULY 12. SINCE THE JULY 12 THE CAR HAS NOT BEEN USED FREQUENTLY IN SITUATION WHERE THE CRUISE IS USED REGULARLY. HOWEVER DURING THE FEW TIMES ON THE HIGHWAY BETWEEN JULY 12 AND NOW, THE PROBLEM HAS REOCCURRED.
