Stopped at a traffic light my power steering warning light on the dash came on. After that I had no power steering, and the vehicle is very difficult to steer. I drove back to my location turn the vehicle off and who won out about an hour later started and the power steering was working. Upon looking the issue up online I found that other models of my Tahoe have had a recall but no particular model has not.

The truck kept staying there on 1st gear, So i had call someone to come pick it up where I was at.

MY NEW 2020 TAHOE HAS AUTO/POWER PEDAL HEIGHT ADJUSTMENT. IT ALLOWS BOTH PEDALS IN UNISON TO BE LOWERED OR RAISED FOR COMFORT AND DEXTERITY OF USE. THE HEIGHT DISTANCE BETWEEN THE BRAKE AND GAS PEDAL IS EXTREME. THERE IS A INHERENT DANGER OF HITTING THE SIDE OF THE BRAKE PEDAL PRIOR TO GETTING ONES SHOE ONTO THE BRAKE PEDAL. WOMEN WEARING SANDALS OR OPEN FACE FOOTWEAR CAN POSSIBLY SNAG THEIR FOOTWEAR TO THE SIDE OF THE PEDAL PLATFORM. ANY HEAVY WORKING TYPE SHOE IS ALSO PRONE TO HITTING THE SIDE OF THE PEDAL FIRST. MY WIFE AND I BOTH NOTICED THIS DURING OUR SEPARATE TEST DRIVES. IN EACH CASE, THE TIMING OF ACTUALLY ENGAGING THE BRAKE PEDAL ENDANGERS THE DRIVERS ABILITY TO SLOW OR STOP HIS VEHICLE. ACCIDENTS WILL OCCUR. I ASKED THE SALESMAN IF THE PEDALS COULD BE SEPARATELY ADJUSTED, TO WHICH HE STATED IT WASN'T POSSIBLE.THE INABILITY TO ADJUST EITHER PEDALS HEIGHT INDEPENDENTLY FOR EACH DRIVERS DEXTERITY OF ENGAGEMENT IS IMPORTANT. WOULD BOTH AUTOMATIC POWERED SIDE VIEW MIRRORS BE EFFECTIVE IF THEY WERE SET TO BE ADJUSTED IN UNISON ONLY ? I'M NOT SURE WHEN AUTOMAKERS MADE THE DECISION TO NEGATE THE ABILITY TO ADJUST THE DISTANCE OF HEIGHT INDEPENDENTLY OF AT LEAST ONE OF THE PEDALS. THIS IS OUR FIRST VEHICLE PURCHASE SINCE OUR LAST IN 1985. IT APPEARS TO ME, THAT IT HAS BEEN AN UNAPPARENT OR UNNOTICED POSSIBLE REASON FOR ACCIDENTS. PLEASE LOOK INTO THIS MATTER. YOU MIGHT FIND MY OBSERVATION TO BE VERY LIKELY. *TR

Rear view camera goes off starts with striped blurry lines then goes to blue screen says âservice rear vision systemâ. Took to dealer battery tests low. They recommend replacing battery, positive and negative cables to the tune of $1000. They arenât positive this will fix it they say this is what they start with there are several errors codes with that system message. Not covered under extended warranty because they say itâs wear and tear/maintenance. Havenât had issues with the battery just the rear view camera system. 2020 Tahoe LS 3 yeas old. Battery shouldnât be bad this soon. Chevrolet needs to recall this rear camera system.

When I make turns/curves my Tahoe will periodically lock the wheels on the opposite side and pull our vehicle to the other lane of travel. Iâve noticed previous recalls on other Tahoes for the same thing and the delearship claims they canât replicate the problem and our vehicle is not included in that recall. I have had the vehicle in Auto and 2wd and it continues to happen. I can disengage the 2wd to auto and vice versa and it sometimes feels to help the problem. I have also disengaged traction control and that will seem to help as well. This has been happening on and off for over a year.

Fuel pump

Check engine light illuminated then went off and came back on after another drive cycle. Vehicle began to idle rough and experienced hard shifting and acceleration hesitation. I checked the oil and noticed a fuel odor smell on the dip stick and the oil appeared thin. Upon mechanic inspection they found a malfunctioning high pressure fuel pump. This part was recalled on other vehicles of the same model year due to bad welds. This could have resulted in fire if left unchecked.

Brand new set of tires. Less than 100 miles on them. During a left turn at roughly 15-25 mph the entire tire separated from the rim on the rear passenger wheel. The tire is in a secure location and can be inspected if needed. This led to an accident. There were no warning indicators such as low pressure indicators. The low pressure indicator came on after the tire came off the rim. The car went from make a 90 degree turn to making a 45 degree turn and cause my SUV to smash into a house.

VEHICLE SPEED CONTROL

My engine light keeps coming on randomly. When this occurs, the dashboard lights blinks and I get a " steering assist" error message. Once this happens it is really hard for me to steer AND I lose acceleration as well. Imagine losing acceleration in the middle of an intersection. Also, I noticed my temperature gauge moves up & down as well. I have taken it to the dealership each time it happens and they are saying they haven't been able to replicate the issue. The engine light only stays on for a few hours or days and the problem goes away once the engine light is off. From my research, this was the same exact problems the 2015 Chevy Tahoes had as well. I don't understand why they cannot figure why I am having this issue. The engine light errors code listed alot of issues yet they still can't diagnose a problem. They have updated the system and checked all wire connections per the dealership. This is my third or fourth time complaining about this issue and this is the dealership's third or fourth time trying to diagnose the problem but they keep telling me they can't.
