I have a 2016 volt bought from NYC and I am the first owner currently residing in TX. My volt currently has mileage of 30,020 but this propulsion power will be reduce error has been shown since last 100 miles or so, my commune is usually under 5 miles a day so I rarely use gas however recently due to work I have to commune pretty far for a week and relied more on gas and this error popup during on of the commune. (It slowed my car down significantly while on highway and eventually stop with message on the console says engine offline) With the following error codes found: P0031 P0054 P0030 P0135 P0403 P0405 P0443 P0458 P0489 P0597 P0598 P06DA P06DB P0AC4 P0030 This car barely has much gas mileages as it was primarily on electric, but this failure on highway comes suddenly.

I-??m experiencing the infamous -??shift to park-?? error. After entering a parking spot, I come to a stop, shift the car from Drive into Park gear, and attempt to turn the car off but it will not turn off because it thinks the car is still in Drive gear mode, and it says -??shift to park-??. It happens intermittently and unpredictably from when I bought the car 2 years ago until now. Sometimes I have to shift back into drive and then to park several times in a row before it finally shows that it-??s in Park gear.

The vehicle issues a message to move the gear shifter into park (shift to park) message even when it is already in park. The vehicle will not engage nor will it enable the driver to turn the vehicle off which results in unsafe driving circumstances and strands the drive in untenable situations. This is known in social media as the "shift-to-park" problem with Volt and other GM vehicles while GM is hush-hush about the issue. There absolutely needs to be a recall issued for all affected vehicles as this is clearly a manufacturer design issue given all of the problems drivers are having. It starts as an intermittent problem and continues to get worse over time with out any warning.

Unable to turn off car when shifter is physically shift to park, but dash warning has a "shift to park" warning. Back in Dec 26 I bought the car in for the same issue and the shifter cable was replaced. But shift to park warning returned a few months later. It is a matter of time before this issue will return.

The Volt center display has gone blank, probably a bad screen. The display serves multiple purpose: Infotainment, navigation, charging control (being an electric vehicle), and most importantly the back up camera display. The rear hatchback visibility is very poorly designed, with great dependent & reliance on driver to use the back camera. Without the display, backing driver can not see a small child nor any object.

Engine became disabled while driving, displaying a "power reduced" message. The vehicle was in motion on a busy street, and I had to try to pull over with traffic moving at a fast pace. This happened to me twice. Dealership was unable to replicate the problem and did not do anything to fix.

In regard to recall 16055 reprogram hybrid powertrain control; module 2. I had this recall done on January 5, 2017. This service changes some settings without notification to the owner. Critically important it changes the engine run on remote start from off to on. If the owner starts their car to warm up in the garage the engine will run unknowing to the owner. This could be a very dangerous situation for the buildup of carbon monoxide in the garage.
