2017 Chevrolet Suburban: engine stalls while driving

Filed Dec 18, 2025 · Electrical, Engine · IL

While driving, the vehicle has repeatedly experienced sudden loss of power and electrical failures without warning. During these events, the dashboard flickers, warning messages appear, and the vehicle shuts off or goes into reduced power mode. When this occurs, steering becomes extremely difficult, braking becomes stiff, and the vehicle cannot accelerate. These incidents have happened multiple times in different driving situations, including: At stoplights While pulling into intersections Backing out of parking spaces Driving on public roads, including dark rural roads Driving with my three minor children in the vehicle On at least one occasion, the vehicle shut off while pulling onto a road with oncoming traffic, leaving us stopped in the roadway with no power and limited steering/braking. This created an immediate and serious risk of collision. The vehicle eventually restarted after several attempts. The problem has occurred repeatedly over many months. Multiple independent repair facilities have attempted to diagnose and repair the issue, but no definitive cause has been identified, and the failures continue. The vehicle has had numerous electrical, sensor, engine, and powertrain-related repairs, yet the loss-of-power events persist. Because the vehicle can suddenly shut down while in motion and compromise steering and braking, I believe this is a serious safety defect that could result in a crash, injury, or worse.

The contact owns a 2017 Chevrolet Suburban. The contact stated while driving 10-15 MPH, the check engine warning light illuminated.

Then the vehicle was taken to the dealer who diagnosed that six of the eight fuel injectors had failed and needed to be replaced. The contact stated that the failure had been reoccurring and the vehicle had been shuddering while driving and while reversing. The contact also stated that the vehicle would jump and hesitate to respond when the accelerator pedal was depressed at the stoplight.

Vehicle dash and headlights turn off while driving, engine stalls and dies, power steering becomes inoperative. Transmission pops out of gear and freewheels. Service stabilitrack light. Very dangerous situation for my wife and 5 kids when this happens on curvy backroads at night like just happened last night! This is also the same problem as our previous chevy tahoe so we knew the problem was likely related to poor quality battery cables that are degrading prematurely. This should not be happening on a 3-4 year old vehicle. After searching a gm web forum and finding other people complaining about the same issue, there was a reference to gm tsb 18-na-161 on this exact issue I am absolutely amazed that gm has not done a recall on this yet, as it is a major safety failure likely to cause a crash and potentially a fatality. I checked the tightness on the connections by hand, which were both very tight, then I reseated and torqued the battery terminal connection. I measured the resistance across the power jumper, lug to lug. This is gm part number 84494554, and I measured 0.3 ohms across this little section of wire at multiple points on the lugs. Trimming back the insulation and continuing the measure, the highest resistance appears to be coming from the wire to the lug connection at the fuse bus, and not the crimp connection at the battery terminal, and not the bolted connection to the bus. There were some strands broken at this connection. I made and added a temporary jumper of the same wire gage, and the resistance across the same measured points dropped to 0.0 ohms. Absolutely a major safety issue if the vehicle suddenly dies without warning. I can see this same issue happening once, I forgave gm once years ago, but with the same issue happening to two different vehicles 8 model years apart, the safety of my family is too important to buy gm product in the future.
