Yes I am filing a complaint due to my high-pressure fuel pump line and also the fuel pump. The fuel pump works but it is very dry rotted on the top therefore resulting in a lot of cracks and pressure loss. I have a 2016 Chevy Colorado four-door. When I go to look up recalls there is recalls on the 2016 to 2018 Chevy Colorado-€™s due to this exact problem. But when I call Dell Earnhardt Chevrolet in Tallahassee Florida they state that it does not include my Vin number. I think it-€™s kind of funny that my truck is having this exact issue but not this phone number please obviously the recall needs to be expanded to include my Vin numbers. Anyway it goes I have a 2016 Chevy Colorado that I paid cash money for and there is no way should my fuel pump be dry rotted and cracked like it is and the fuel pump is still in working condition. What led me to this diagnosis was I was driving down the highway when multiple times my vehicle jaunted to a halt. I was able to crank it back up and go a few more miles before it would happen again. At this point I took it to my mechanic to put it on a code reader and it was reading fuel pump modular. I Cut a hole in the bed of my truck and was able to save fuel spraying everywhere for my high-pressure fuel pump line. I ordered this line from Dale Earnhardt Chevrolet for $62. When we get there and put the line on the fuel pump it is the fuel pump nipple and the top of the fuel pump is extremely dry rotted and cracked. There is no way should the fuel pump be dry rotted and crack on a six year old vehicle. Like I said the light never came on till after a few times of shouting me to a halt and this is my complaint

After fueling, the vehicle cranks but does not start. After sitting for approximately 10 minutes, the engine will start but idles roughly for a few more minutes. Also after long highway drives, the engine will run roughly and occasionally stall when the vehicle is stopped. Vehicle was brought to dealer who diagnosed as a faulty purge solenoid. This is a known problem in 2015 models as detailed in GM special coverage adjustment letter #18029. This 2016 model year is not included.

The check engine light came on it popped up engine power reduced wouldn't go over 35 miles and hr on the interstate is not a good thing. I pulled over turned car off. Turned key back on started it was fine. A couple weeks later pulling out in traffic check engine.light.comes on and loses power again almost get hit. Go to parts.store to plug machine for diagnosis. First it said unknown. So we do it again PA201 00 code. Computer said CO2 sensor. I was told a tsb bulletin came in for this software update but nobody wants to talk about it they just want to fix it then charge.U for it.but.I think it should be covered software issues shouldn't be absorbed at customers exspense. My truck is a turbo diesel its hard to find parts for it at part store and diagnostic machine just getting in oil filters. Anyway in response of software it should be covered by someone else besides me. Before it loses power and vet's me killed or I. a wreck need issue resolved

2016 Chevy Colorado with less then 10,000 miles. At low rpms on any incline truck will buck, sputter, and hesitate rather than automatically shift into lower gear. In city traffic, after slowing to make a turn then accelerating, truck will buck and sputter and drive train will make a hammer sound after engaging. I took it to dealer who said he could not duplicate problem, although this is a known problem.

Ongoing problem with diesel fuel leak which began in October 2017. Will be returning to the dealer on 27 March 2018 for cause search of the problem and repair. Dealer confirmed one of the diesel fuel leaks during November 2017 was a leak at the fuel pump and a loose fuel line. Problem has returned after 3900 miles of use. Diesel fumes permeate the cabin and diesel fuel covers the driver's side of the truck from the front wheel well along the body to the rear left bumper. Have contacted Chevrolet corporate during November 2017 to make them aware of the problem and create a formal case report. Have started another case report with Chevrolet as of Friday (23 March 2018) to seek a permanent and durable resolution to this problem.

Vehicle has erratic downshifting and upshifting of the automatic transmission causes abrupt changes in acceleration and deceleration that sets up sequences that force the driver to continually press down on, or let up, on the break and or accelerator to attempt to blend in with stop-and-go traffic. Only getting 15-16.5 mpg city driving.

This vehicle's erratic downshifting and upshifting of the automatic transmission causes abrupt changes in acceleration and deceleration that sets up sequences that force the driver to continually press down on, or let up, on the break and or accelerator to attempt to blend in with stop-and-go traffic. In very heavy traffic, present when entering or leaving large cities, the onset and continuance of this vehicle's performance worsens resulting in driver fatigue and extreme stress, brought on by the ever present necessity to be extra watchful and to maneuver to avoid hitting the vehicle in front, or being rear-ended. When driving through mountainous terrain at today's interstate speeds, there is recurring "bumping" that sets up when ascending long grades. It creates the feeling that either the transmission is attempting to downshift but then changes its mind, or the engine's RPM are about to increase but don't. this adds to fear of imminent failure and being left stranded. This behavior was present from the very first time the vehicle was driven. It's getting worse.this driver believes the unsafe operating performance of this vehicle as described above, is exacerbated by the combination of the small, 4 cylinder engine coupled to the 6 speed transmission, that requires the engine to rapidly downshift or upshift to provide the needed performance required in today's driving environments. Further, it is evident the software controlling the transmission's operating behavior was neither fully developed nor tested throughout its anticipated full operating range and as such creates a vehicle that is dangerous to operate on public roads attempts to have these issues addressed with the dealer resulted in being told..." nothing can be done...the problems you are encountering are being are being experienced by many customers. Chevrolet is not providing any solutions".

When merging onto I-70 freeway from on-ramp, I applied throttle to move into the traffic flow. Engine "stumbled" as if in a dead spot. Truck did not accelerate and appeared to be lugging badly. Transmission was in too high a gear and seemed to be searching for correct gear. During this time oncoming traffic was forced to brake and there was a near miss of having a rear-end collision. All I could do was watch in the rear view mirror as traffic converged on me. This "dead throttle / wrong gear" issue has happened repeatedly on surface streets but luckily on surface streets I was not in such a critical situation. This is a problem that has been reported repeatedly and at many places on the internet. When will NHTSA force GM to address this issue? hopefully you will act before this results in serious injury or fatalities (if it already has not). Please act!
