At 92,000 miles the lifters went out in vehicle. Repairs were done and replaced the gaskets, lifters and head bolts. After driving the vehicle another 12,000 miles lifters went out again. GM is aware of the issue and does not to take responsibility or make a recall on the issue. It’s a very known issue with the 5.3L engine in cylinder 1 to have a lifter failure.

There was a recall in 2019 (NHTSA Recall No. 19V645000) on certain GM vehicles for vacuum pump failure, which could affect braking and engine performance. The fix usually involved reprogramming the ECM to improve how the brake assist system operates - not necessarily replacing the vacuum pump unless it had already failed. My local dealership did the reprogramming but in 2025 the vacuum pump totally failed and left my vehicle stranded on the interstate. I had to have towed to a mechanic shop and the inside of the pump had broken into 3 pieces. So I had to have the vacuum pump replaced. During this time my car did not have brakes and put me and surrounding vehicles in a very dangerous situation. The mechanic gave me the broken part to show the dealership. The dealership said there isn’t anything they can do for assistance as I am out of warranty. There was a message that came up that said to service the braking system right before they stopped working.

The contact owns a 2017 Chevrolet Tahoe. The contact stated that while driving on the highway at 70 MPH, the vehicle lost automotive power. There was no warning light illuminated. The contact was forced to pull over and had the vehicle towed to a local independent mechanic where the vehicle was diagnosed, and the contact was advised that the transmission was faulty and needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure. The approximate failure mileage was 128,000.

The contact owns a 2017 Chevrolet Tahoe. The contact stated that occasionally while driving at various speeds, the vehicle failed to accelerate as intended while the accelerator pedal was depressed, and the RPM was elevated. In addition, the contact stated that the vehicle would brake independently while the accelerator pedal was depressed. The check engine and Electronic Stability Control warning lights would occasionally illuminate. The contact stated that restarting the vehicle was a temporary repair; however, the failure persisted. The contact stated that the windshield wipers activated independently, and all four doors locked independently. The vehicle was taken to a local dealer where it was diagnosed with a fuel injector #6 failure; however, the part was replaced approximately one month prior to the failure reoccurring. The vehicle was not repaired due to the cost. The contact related the failure to NHTSA Campaign Number: 19V761000 (Service Brakes, Hydraulic, Service Brakes, Electronic Stability Control (ESC); however, the VIN was not included. The manufacturer was made aware of the failure. The failure mileage was approximately 95,000.

The transmission dropped 2 thousand miles over my warranty at 102k miles. I was taking my son to see his surgeon and the car started jerking and making noises in the middle of a busy intersection. We almost got hit several times trying to get it to the side of the road for safety. I had to pay almost $1800 to get it towed home (we were in Peoria about 150 miles from home to see his doctor). There were no indications the transmission was going out and never should have at that mileage. I always do regular maintenance and keep all my receipts. I then paid 6k out of pocket to have it replaced with a better transmission since I learned GM put a bad transmission in the Tahoe I have (I was told I missed the time limit to have it fixed on their dime). Then 6 weeks later a fuel injector and the lifters failed due to the active fuel management. No one was hurt thankfully because I was just leaving home to go to work when I noticed the tapping sound and had my mechanic come look at it. Him and 2 other mechanics confirmed it was the lifters. I had already borrowed money to replace the transmission and can’t afford the $12k quote to fix it. Now it has been sitting in my driveway for almost a year unable to be driven. It is however causing me severe depression. I’m borrowing my son’s car while paying almost $700 monthly on a Tahoe I can’t even drive. I was even more sad when I found out there’s thousands of people with the same issue. GM should be ashamed of themselves!

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.
