The transmission is slipping and I only have 77,000 miles. Is this normal? the van is only a 2013 model.

This vehicle will not turn off when the ignition key is removed. This poses a great risk to any passengers in the vehicle as it can be moved without the key in the ignition. The vehicle remains fully powered with the key removed.

Vehicle goes into engine reduced speed and service traction control and service stabili track warning lights turn on. I have had this problem starting a week after I purchased my van and was "repaired" on numerous occasions and the problem keeps reoccurring. The incidents happen while driving and when stationary while engine was running. The dealer replaced the accelerator petal assembly a couple of times and also replaced the throttle body position sensor and the problem still continues. The last time I took it in the dealer put dielectric in the harness and said I might have a moisture problem. The problem reoccurred again a few weeks later. I don't see how moisture could be the problem since it started a week after purchase and continues 4 years later.

The contact owns a 2013 Chevrolet Express. The contact stated that there was a warning light that randomly flashed, indicating a loss of engine power. In addition, the vehicle randomly stalled more than once. The failure was reported to a dealer, but they did not have the tools to provide diagnostic testing. The manufacturer was not notified. The approximate failure mileage was 2,000.

The vehicle randomly and autonomously applies the brakes and cuts engine power while driving. At this time the vehicle states "service stabilitrak" and the icon flashes that I am skidding, which I am not (I have video proof of this occuring). After 4 trips to the dealership the problem still persists. It is only a matter of time for this to occur while merging, or making a left across traffic and cause a serious and potentially fatal collision.

The contact owns a 2013 Chevrolet Express. The contact stated that the vehicle failed to start and the engine warning light illuminated. The failure recurred twice. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was 65,000.

The first and second (of three incidents) both appeared minor, lasting only a fraction of a second. About half way through a 150-mile drive, the engine went dead but as quickly fired up again so as not to be taken seriously by me. But a third incident was worrisome. While driving about 50 mph on a straight, flat-and-level stretch of a macadem farm road, the van suddenly, very abruptly, shifted into what must have been its lowest gear, and during about 15 or 20 seconds thereafter it jerked back and forth as if it were struggling to climb a very steep hill. I had not been shifting or trying to shift gears, and had been traveling uneventfully before I was thrown against the steering wheel. (no brake lights would have warned other vehicles that the van was abruptly slowing down, had I been in busier, fast moving traffic.) I visited the (fairfield, lewsiburg, pa) dealer from whom I bought the brand new van, and he appeared unable to discover anything wrong but "brushed" clean the contact points within electronic displays (as I understood his explanation) on the dashboard. But the incident could not be duplicated just by test driving. However, my concerns grew at the prospect of again driving long distances on busy highways. I emailed Chevrolet (as directed in the van's manual).. last I recall, Chevrolet asked that I return a survey sent to me over the internet, but each of numerous times that I tried to, using the password they provided, I could not access the survey. That survey snafu may be worth mentioning because when I complained about their web site not functioning, they replied that they had no problem accessing the survey! odd reaction? so I was not able to complete the survey, which is partly why I am sending this message instead to you. (the van to date has fewer than 2,000 miles driven.)
