  1. General Motors, you are killing the making terrible changes to you cars. The corvette doesnt even have an actual steering “wheel” anymore, i wont even look at it, its not a dammed grand prix (f1) btw it never was and never will be. The camero no matter what it changes to will never look as nice as the 67-69 classic, i do not find it apealing. You, like many others are killing the car made for the real driver at heart aka the manual gearbox shifter and your new cars are whacky in design and full of nonsense computer crap that i know isnt nessisary to stay safe it only takes a good driver. We the people are diverse and need availble options for all i see nothing but cars and trucks made for the futuristic lazy idiot dricer in mind. You have recently canned the impala the nicest sedan you had to offer. My last chance of getting somthing that actually apealed to me died with the chevrolet s.s. I see no pationate driven future for the american auto industry whatsoever, its a dammed crying shame in my eyes and i hope that future tech such as touch screen and l.e.d headlamps does not become the standard to highend trim levels in time to come as they do not much but drive up the price of cars and a burden and safty hazzard to road safty and of course i myself do not apeal to such things as i have a big screen TV at home and dont need another one when i cruising enjoying the beautifil sceenery trying to reach for the dial that isnt on the dash board anymore.

  2. GM message of discrimination 7/7/2020 (approx)
    Account Number –

    Date is an estimate (It is logged I am sure in your system)
    Hello, after more than 30 years in the workplace and a 26 year career with the US Government (Retired) for the first time in my lifetime I was laid off from my Chief Operating Officer position due to COVID19 (company closed its doors and sold overseas). I have never expected or imagined this to ever happen to me (as no one does). I called GM to ask/beg for assistance and the very RUDE associate asked me a few questions like, are you working? I responded with the above and she said so you have no income? I responded, yes UNEMPLOYMENT but based off of my prior over $100,000, 6 figure income I am in absolute turmoil now with life in general, with that she responds, OH, $100,000? IF YOU HAVE NO INCOME I CANNOT HELP YOU, YOUR BEST OPTION IS TO VOLUNTARILY SURRENDER THE CAR! I was totally shocked by her response and attitude. I hate to think this way but what I am about to say is 100%, she heard I was a WHITE, MALE making over $100,000 and she had her response already made up the within the first minute of our conversation. This is absolute discrimination and with all going on around us how is this being permitted by companies such as GM who I have held to a much higher standard than this? I have never in my almost 50 years felt so demoralized for a situation I had no control over (being laid off due to COVID19). She offered no options or solutions besides JUST TURN THE CAR IN. That is the last thing I would want to do on top of all of my other issues impacting my family and I at this time of pandemic. This call was recorded I am certain so you can go back and listen (my wording above is not exact I am sure but very close to verbatim). I am willing to take this to a higher order to let the public know that GM states they are here to help during the trying times of COVID19 but that is not the case when their Customer Service Reps have made up their minds on the situation based on the customers Race, Color and Creed. I have worked extremely hard for everything we have and to have been treated like this when my anxiety is at an all time high is absolutely fortuitous in a time of need. I expect action to be taken immediately on this CS Representative and a resolve to my need at this time. Please contact me immediately.

  3. I ordered my 2020 Corvette convertible in November of 2019 the only reason why I did was because I was guaranteed the Corvette by late may early June because my lease on my car is up in August I know the Corvette plant closed for a while my production number is 1100 nobody at my dealership or anywhere else knows what the h*** is going on nobody can tell me anything I’m even hearing I could have to wait til the 2021s come out which is not acceptable my least will be up in August and I won’t have a car I am hearing that certain production numbers will have to wait til the 2021s which is really bullshit because you should honor everybody who has been waiting patiently and so long for their cars they should get their 2000 twenties before production on 2021s start… I have had corvettes in the past but this is ridiculous that you would do this to people who have ordered corvettes 8 months ago

  4. I understand it’s aimed at improving gas mileage, but the “auto stop/start” feature is perhaps one of the most annoying features to have ever been developed. What makes it worse is that not all vehicles come equipped with a disable button (my 2020 Traverse as such). GM, please push out a software update to allow your technicians to turn this function off if an owner so chooses. Thanks!

  5. After seeing your trucks at the white house with dictator Trump I will never buy another gm product. I do not and will not support the overthrow of the USA by Fascist pigs.

    1. What an uninformed idiot you are! The liberals have been leaning to socialism in recent years and now progressive liberals actually brag how they will turn this great country into socialism. You may find a multitude of reasons to dislike Trump but you are dead wrong about any such agenda coming from him. My goodness man, do some research, read your history. Clearly you have no clear understanding of the meaning of fascism and easily being blindly led by other uninformed idiots. But then again, birds of a feather…………………….

      1. Trump is court and self convicted fraud. Other than his Impeachment, on of his more recent convictions was the “Trump University” case that he wilfully and without threat, duress, or coercion plead guilty. Feel free to set an appointment with a court clerk for details of your fraudulent president’s public court conviction record.
        If you would not wilfully hire a one-time court convicted business fraud for a common business manager position. Why then would you elect a multiple-time court convicted business fraud for president of political corporation?

  6. i have been a chevy man for at least 50 yrs, and looked with great expectations of purchasing the new blazer… man was i let down when i saw it,,, IT IS PURE UGLY. THE GUYS THAT DESIGNED IT SHOULD BE FIRED, INSTANTLY,




  7. I have a friend in Pakistan who wants to apply for a workers Visa to work anywhere in the United States. Do you hire immigrant workers and are you currently hiring? What are the requirements you need for employment and for which positions?

  8. This is Bonnie Frymier, I bought this Chevy Trax at Flatwoods West Virginia and took my car and showed them the paint is peeling off my hatch under the back glass. They were suppose to contacted you over 2 months ago. The Trax is a 2016. I think GM should pay for getting it painted. I don’t care how many miles it’s got on it it shouldn’t be peeling off. It’s bad business when people are seeing the paint coming off. I have had alot of other problems with this car. Would never buy another one. Hope I here from you.

  9. I wanted to Share my Story…I was taken my Mom around looking at new cars, she just retired and wanted something with a warranty. She really didn’t know what she wanted, etc, all she knew is she didn’t want a thousand phones a day. So on mission and remind you she was in no hurry but want to make the right choice because she wanted to last for a long time. We stopped in Pinkerton Chevrolet Buick GMC in Lynchburg where we met Jason Fisher. He answered questions and gave us his card and said call me with any questions, I’ll be glad to help. Along our mission we ran into all kinds of Salesman but my mom fall in Love with the Buick Encore. So this was our new mission to find the best deal so we start shopping for the best deal. My mother many years ago bought a car from Berglund in Roanoke so we went up there to see what they had to offer. I called a spoke to another young man name Jason he was a pleasure on the phone, however when we got there (over a hour drive) when was assigned to a salesman Jeff. He put us in his office and we waited. He was running the show! He kept trying to get info from us as if he already had the car sold. Finally when we made it to the lot they didn’t have what my mom wanted she want power seats and solid print seats. Jeff said what if we can get that for you at a lower price would you be interested, well yes! He had his manager (I assume)come out and stated this and that however the price kept going up. I told him we had to think about it and if we decide to buy from them we’ll be back, his words was NO YOU WON’T. Very rude I felt we was treated this way because we was two woman. So not to drag this story out much longer, I want GM to know how wonderful Pinkerton was they gave my respect and Jason went above and beyond to make my Mother happy. Berglund could learn a lot from Lyncburg. I personally wasn’t planning to get a new car yet, however was so awesome not only did my my buy a car, I did as well. So buy not being pushy and just be willing to answers a woman thousand questions he got two sales and a we got a friend for like.
