2017 Chevrolet Suburban engine problems

On 5/28/25 the vehicle was on the interstate and presented a check engine light. Shortly after getting off the interstate the vehicle limited speed. This was taken to the dealership and they replaced the #6 injector. This vehicle was identified as having a left bank tick on 11/18/22 by the dealership but could not be duplicated by the mechanic. On 5.8.23 the #8 injector was replaced due to code and the vehicle vibrating at low RPM and at stops both in park and in drive. On 5/28/25 the #6 injector was replaced due to code and rough idle. They also replaced all spark plugs. On 12/29/25 the #8 injector was replaced again due to rough idle and code. On 6.23.26 the vehicle was again taken to the dealership due to rough idle. Nothing was done. On 8/18/26 the vehicle was taken to the dealer for a rough idle again. The dealer found no codes but wanted to change the oil to troubleshoot. I allowed it telling them changing the oil would not correct the misfire. Even though the misfire was present after the oil change the shop foreman would not troubleshoot further due to no code displayed. I purchased a scanner and found 81 misfires on cylinder 7 for the current cycle.

Component or System Failure The vehicle experienced two major mechanical failures. First, the transmission failed and required full replacement shortly after the expiration of the 60,000-mile powertrain warranty. At the time of this failure, the vehicle had approximately 61,000 miles. Second, at 100,119 miles, the engine suffered a catastrophic failure that required complete engine replacement. Safety Risk The transmission failure impaired normal drivability and created a safety risk due to reduced or unreliable propulsion, which could have resulted in loss of power while driving in traffic. The engine failure rendered the vehicle inoperable and could have posed a serious safety hazard if it had occurred while the vehicle was in motion, including sudden loss of engine power. Problem Confirmation and Inspection Both failures were diagnosed and confirmed by dealership service personnel, who determined that full replacement of the transmission and later the engine was necessary. The issues were identified through inspection and standard diagnostic procedures. Warning Lamps or Symptoms There were no clear, persistent, or meaningful warning lamps, messages, or symptoms that would have reasonably alerted the driver to an impending transmission failure prior to it occurring. Any warning indicators appeared at or immediately before the failure. Similarly, there were no significant warning signs that would have predicted the engine failure prior to the need for complete replacement. Additional Information Both the transmission and engine failed at relatively low mileage for major powertrain components. The transmission failure occurred just beyond the powertrain warranty threshold, and the engine required full replacement at 100,119 miles. . These failures suggest a potential defect or durability concern affecting critical powertrain systems.

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.
