2017 Chevrolet Tahoe electrical problems

They radio screen and radio navigation system. It will run batteries down replaced 2 Batteries this year. Radio goes haywire changes channels, makes dinging sound, navigation goes off. Screen moves jumps changes volume. Hard to drive very distracting and navigation stops working. None of this will stop until the vehicle is turned off and generally on restart it starts back up. Makes for very unsafe driving distraction. It started about a year ago it would happen occasionally now it’s every time you start the vehicle and drive. The constant noise and movement is again unsafe distracting and disrupts driving and anyone trying to have a conversation in my vehicle. Very very unsafe…

My car has a problem This will be the 3rd visit to the Chevy dealership and the 6th time in a garage. At this time, the original alternator that came with the Tahoe, was running high through December and replaced with a new alternator from Parts Geek. It was ok for a couple weeks and is running high again. You cannot test it from a cold start to get this reading. It must be ran for at least 20 min. After a certain amount of time the battery gauge will move to the highest point, the warning lights of ABs, traction control, stabilitrak, trailer brake light, battery light (first time on 1/27/2026 for battery light), loss of drivers assist on 1/26/2026, tire pressure light, car dies coming to a stop sign. I can’t turn it back on for at least a min. I’m stuck inside with zero power, can’t unlock the doors to get out to direct traffic, open windows or put on 4 ways so I don’t get smacked in the middle of the road. After that minute I heard a click (no key in ignition, not trying to start) and then the dash lights started coming back on again and I started it. The battery did not restart the time on the radio screen so I’m assuming I didn’t die fully. The radio screen always goes black first, then the heat goes in and out, the warning lights come on and it dies. Takes a minute or so to be able to start it again and the lights aren’t on anymore but will continue to do the same shit after awhile of driving and now daily. I’m afraid to drive it anywhere since almost getting stuck inside and plowed at an interaction. I have reached out to Chevy about this problem and was referred to take it back to the dealership again, and to reach back out as soon as it’s there to open a case on the issue.Ive had it, this has been ongoing for a year, and I have to keep paying for things that doesn’t fix the issue and it’s getting worse.

The system that I believe to be failing has to do with electrical components of the 2017 Chevy Tahoe. It has completely lost all power two times while driving this vehicle. In both instances, mine & my children's lives were at risk including those who could have hit us. If anyone had been behind me as I was turning and the car shut off mid turn, it's possible we could have been hit by a vehicle(s) going 50+ mph. It's available to you to be inspected if needed. The vehicle has been evaluated by a mechanic who says he cannot find any specific 'problem' but did have to turn off multiple error codes. The chevy dealership thinks it may have to do with the remote start antenna. This has not been reproduced by a dealer or service center but it has been reproduced by myself when I attempted to drive the car again after the error codes were turned off. I also have confirmation of this happening to another person who owns a 2017 suburban and after servicing the car they continue to have issues. They were entering onto a highway on the on ramp and their car completely lost power and stopped- I would hate to see what could have happened if this was on the highway itself as it could have had the potential of lives being lost. The only warning messages I have seen had to do with servicing the remote start, which has never worked for us despite having it worked on prior to purchasing the vehicle. There were messages about stabilitrack the first day this incident occurred but not the second time that it occurred. Both times the car will turn back on after about 5 minutes but it's as if the cars system was completely reset (clock at 12, radio setting default, etc). The fact that I know of one person with a 2017 Chevy that this has also happened to, I believe an immediate recall should be initiated as I will not be driving this vehicle until there is an answer to save our lives and others on the road.

The contact's brother owns a 2017 Chevrolet Tahoe. The contact stated that while driving 70 MPH, the check engine warning light illuminated, and the message "Reduced Engine Power" was displayed. Additionally, the vehicle decelerated to 20 MPH. The contact was able to pull to the side of the road. The contact stated that he turned on the hazards lights and continued driving 20 MPH. The contact stated that upon arriving to his residence, he connected an OBD reader to the vehicle and read diagnostic code P2138, which indicated an accelerator pedal sensor failure. The contact stated that he replaced the part himself; however, the failure persisted. The vehicle was taken to the dealer, where it was determined that there was water leaking inside the vehicle from the roof antenna mounting point, which caused the driver's side fuse box to rust, causing electrical failures. The vehicle was repaired. The manufacturer was notified of the failure and referred the contact to the federal safety agency Hotline for assistance. The failure mileage was unknown.
