2017 Chevrolet Suburban: check engine light

Filed Oct 16, 2026 · Engine · ND

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.

What component or system failed or malfunctioned, and is it available for inspection upon request? The fuel delivery system has failed. Specifically, the fuel lines are leaking at the connection point on the top of the fuel tank. The vehicle and the affected components are currently available for inspection upon request. How was your safety or the safety of others put at risk? This defect poses an immediate fire and life-safety hazard. Because the fuel leaks while the vehicle is powered on, any spark or heat source could ignite the fuel tank, leading to a vehicle fire or explosion. Additionally, the cabin environment has become toxic; the concentration of gasoline vapors is so high that it causes physical illness. One of my children vomited due to the fumes. The vehicle is currently undrivable because the vapors are intoxicating and hazardous to the health of all occupants. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, the leak has been inspected, reproduced, and confirmed by an independent service center. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No, the vehicle has not yet been inspected by the manufacturer, law enforcement, or insurance representatives. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? There were no warning lamps or dashboard messages (such as a Check Engine Light) prior to or during the failure. The symptoms—specifically a strong odor of raw gasoline—first appeared four days ago. The intensity of the odor and the rate of the leak have increased significantly since the initial onset.

FUEL INJECTORS are malfunctioning. Engine light has come on multiple times flashing and goes off. Took it to Ernie Lee's Service Center & told fuel injectors are not functioning properly.

It started around 100,000 miles & I only have 125,000 miles on it.

A Chevy Suburban is a vehicle made to transport large families. You would assume these are made with true utmost safety precautions in mind to protect families. At just over 47K miles on my vehicle, our transmission went out, even though we have regular maintenance completed on our vehicle. The check engine light came on while driving on the highway. Was able to make it to a shop who verified it was the transmission. Took it to the dealer who also confirmed it is the transmission, and their 4th one on a newer Chevy Suburban to come in just today. They said they have 37 on the lot with transmission issues on newer Chevys, and some blew out while driving. We were very fortunate it did not blow out while driving, but it’s unacceptable for a family car’s transmission to go out with so little mileage. This has to be a major defect and cause for concern.

Vehicle became hard to stop/pressing brakes while pulling into my garage. Had to stomp the brakes hard to stop. There were no warnings prior to this issue. No check engine alert etc. Upon research, I see that there was a recall for a flaw with the suburban’s powered brake-assist system. When I put in my vin number it states that my vehicle is not included in the recall however this is the exact problem I am experiencing.
