While driving up a hill on a road trip the vehicle felt as if it wouldn't speed up when pressing on the accelerator- this was short lived. Upon parking in the driveway after the trip my husband noticed a fuel smell coming from the rear driver side of vehicle. The next day it was difficult to start and fuel smell was even more pronounced. As it was the weekend we did not drive it and waited to contact the dealer on Monday. Drove the vehicle to the dealership to have the smell diagnosed and while the engine was running and vehicle was in park, fuel began pouring out underneath. There were NO warning lights whatsoever. Fortunately our granddaughter had just been taken back to her parents as she had previously been in the vehicle! This could have caught fire!!! The vehicle is currently at the dealership and a leak in the fuel line has been diagnosed and is scheduled for repair as soon as the part comes in.

2016 Tahoe Fuel problems/ transmission jerking mostly going up an incline/hill. Warning ⛔️ lights/ check engine light flashed only 3 or 4 times, I stopped the vehicle, about 5 minutes then I started back to drive . I took it to Edward Chevrolet in Bham Al , I told them I may have pumped some bad gas, because it was spudding & jerking especially when I when up an incline/ hill. But they told me that the gears going out in the transmission & I need a transmission. I took it to them because the truck was spudding when driving. So when I got my vehicle back now the truck making a winding noise, it’s changing out correctly but when I go up incline/ hill , it hesitates, spudding, jerking. I have two other vehicles, I haven’t drove the vehicle enough to have a transmission problem. I asked other people that have Tahoes, even mechanics, said they been having problems with the transmission in 2016 Tahoe & Chevrolet trucks that carry that particular transmission, having the same problems. I think it need to be a replacement of transmission or recall established on the 2016 Tahoes & pickups!!! Sign please help, I don’t have no 6,200 for no transmission & haven’t even driven my truck enough to have a transmission problem! I have 3 more payments on my 2016 Chevrolet Tahoe, I haven’t enjoyed my vehicle it only have 148,000 miles, and the transmission going out , and that’s not right. You all need to check into this and do a Recall!!! [XXX]!! Sign please help INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Fuel started leaking from top side of fuel tank. Seems to only leak while vehicle is running. My wife and family where all in the tahoe when this occurred. Also tahoe would shut down while driving just out of nowhere. Total loss off power and control. After a couple minutes it would start right back up. My family and kids were also in the car when this has happened.

The fuel supply hose/line from the fuel tank to the vehicle connection rubbed through, due to a loose fit where it attaches to the tank, causing a fuel leak. There were no indicator/warning lights, though a hard start/extended cranking time occurred on occasion. Raw fuel could be smelled with a very slight drip, which could only be seen on clean concrete. Vehicle had only 54,000 miles on it and driven very lightly, but does drive on dirt/gravel roads.

On 18 Apr 2022, my 2016 Chevrolet Tahoe LTZ was found to have a gas leak around the fuel tank area when the car was taken to the Chevrolet Service Center for an oil change. On that day, there was both a strong fuel smell and presence of a pool of raw gas. There were no warning lamps, messages or other symptoms of the problem prior to the failure. Additionally, I was not notified by GM/Chevrolet that this could be an issue. After inspection and diagnosis, the service technician found a "rubbed spot" on the the feed pipe and replaced it. He noted that he "made sure the new pipe is secured on tank as designed to prevent future occurrence". This vehicle is used as primary transport for my family. The fact that it leaked gas while I was driving put my family's safety at risk. I also believe that other owners and their families could be at risk. After researching the problem, I have found several posts from other owners and a service bulletin that describes the issue and the service procedures to fix it. I believe there should be a recall for this well-known major safety issue. I have emailed GM/Chevrolet's customer service department and provide them with details of my complaints and supporting documentation also attached in this compliant form. The items are: 1. My service invoice 799356 dated 20 Apr 2022. 2. Picture of the pin hole on the defective fuel feed pipe removed from my vehicle. 3. Service Bulletin 17-NA-304, dated February 2020 which provides guidance to professional technicians on the issue(s) and service procedures to fix it. The first edition of this bulletin was released in September 2017 which is after I purchased my 2016 Tahoe. 4. Several forum posts from other Chevrolet Tahoe and Suburban owners who have experienced the same major safety issue.

Since I have bought this vehicle in 2016 I have had nothing but continuous problems with it. 1.2016 tahoe w/ 96,000 miles began riding extremely rough any speed. So much bounce and jarring that the car is unsafe to drive on any rough road. Took it to the dealer, the magnetic ride control shocks and struts failed and are fully extended. Cost to repair over $3,000 for 4 shocks/struts. 2. My fuel injection is horrible and has caused me to lose mpg on my mileage. It hesitates on acceleration and when it set on cruise - basically all the time like its chugging constantly. 3. My brakes have been recalled and the pressure is not consistent on the,. All of this before I even hit 100,000 miles. I paid $74k for this vehicle in 2016 and I have had to put literally ~$8k in vehicle maintenance in it since. Very very disappointed!!

The vehicle is leaking gasoline from the tank. Suspect it is leaking from the fuel line on top of the tank--no holes or impact on tank apparent on the under side. In addition, the vehicle is still leaking oil from the drain pan even after re-sealed by dealer. This is all in addition to the A/C going out twice....and new lifters in the engine.
