Fed up with my Silverado

There's a related post in the troubleshooting forum posted 20 hours ago titled Battery Voltage meter always reading above 14 volts, or something like that. The poster states the dealer said his battery had a bad cell, which was also why his Auto Stop/Start feature wasn't working, and replacing the battery fixed that issue. Just a thought to consider for the OP of this thread.

They have replaced the battery verified that all is OK, and every time I take it is they change the battery sensor module claiming that is the problem. I am on the 3rd sensor and the problem still exists.

LOL, my truck was built in Mexico on January 3rd. Zero actual issues (little things that i don't care to mention).

The Auto S/S does no real improvement. Technically yes if you sit at light for over 7 seconds it will save you that tiny amount of fuel. If you sit at a light for less than 7 seconds its actually burning more fuel.

I would say (WITHOUT SEEING THE TRUCK), its probably a sensor that isn't connected properly. you live in San Jose, i am in Fremont. i have a MP808 scan tool. I might be able to find the problem, but i would doubt i could find anything since the dealer couldn't. Possibly go to another dealer?

Other than the infotainment issues and the auto stop, I have not had many other issues except for the 5 recalls. I have less than 2K miles on the truck, and I expect more from GM. I could take it to Fremont Chevrolet, but they are owned by the same people that own the dealership where I bought mine. I guess I could try Capitol Chevrolet but that is a farther out drive as I live right next to Milpitas. As I posted to the other reply, they have replaced the battery sensor module twice without success.

I've had some weird issues in 46k miles but that isn't one of them. I turn of ss when I start the truck. When I forget, it works.

A couple of times the navigation quit working stating chip error. The power steering went out for a short time recently and several times during the first 1.5 years the tranny momentarily slipped out of gear then reengaged with a big bang while slowing down and turning right. I'm beginning to wish I had gotten the extended warranty.

Well, I have posted before about the ever present issue of the auto stop feature not working, I know many here don't care for the feature, but with our gasoline over $4 a gallon now, it's important to me). The last time it was in the dealership was on the phone with the factory, and once again I was told it was fixed.....I drove home (12 miles) from the dealership, took the freeway to get it good and warm, turned off all the climate controls (even though I think I should be able to use them) went to a stop light and....nothing! This was the 4th time I had it in to get this feature fixed, each time they tell it's fixed and the first opportunity to use it nothing happens. I also had an issue with my infotainment screen going blank and popping up with a "No Content Found" error, they did a firmware update and it worked fine until last week when I noticed that when I opened the driver side door after shutting the engine down, the radio would keep on playing for several seconds and then it would shut down. It never did that before it used to stop as soon as I would open the door. Then on Friday I was stopped at a light and the infotainment system went blank, no sound no display it lasted about 15 seconds then came back on. Anyhow, I have decided to pursue the lemon law on this truck (I have contacted a lemon law attorney), as this is absolutely ridiculous for a truck with still under 2000 miles on the odometer. I don't know if the problems are as a result of the trucks being built in Mexico, but I am tired of it being in the service department for weeks at a time and the problems don't get fixed.

The auto stop is causing people issues that role to a stop. The engine/computer feel you are crawling along and do not stop the engine. Try coming to a hard stop and staying on the brake. It should engage the auto stop. (of course this may not be your issue but many have used this and resolved.)

Rocz3cqg · March 18, 2021

The Auto Stop is a minor issue but it should work properly and the dealership has acknowledged that a problem exists. Other electrical issues are now raising up. You are right in pursuing a Lemon Law inquiry to prepare yourself. Try a different dealer to see what they can do.

My sons cost for the extra battery that comes with stop stop cost 400$ I doubt there was that much in gas savings. Especially in Texas where it comes on very little. Maybe it helps GM with their gas mileage bragging rights. Does little for the buyers.

Auto start/stop isn't saving you a dime. All that fuel "saved" gets wasted on startup. AFM/DFM are what actually make an MPG impact on these trucks.

That statement hasn't been correct since engines were carbureted. So if you are daily driving a muscle car with auto start/stop, then I agree.

"Contrary to popular belief, restarting your car does not burn more fuel than leaving it idling. In fact, idling for just 10 seconds wastes more gas than restarting the engine."

https://www.edf.org/attention-drivers-turn-your-idling-engines#:~:text=Contrary to popular belief%2C restarting,warm up%2C even in winter.

Now it is debatable how much fuel is actually saved, its probably a few pennies per tank for most of us. My wife's Acadia has the feature, but due to where we live, I don't spend a ton of time sitting at red lights. Other people may see more savings.

I am not sure if it will help, but how hard are you pressing the brake? I don’t mean like slamming and skidding to a stop. Are you a light touch and only press enough to stop? When I had my 2015 Malibu, it had the auto start/stop on it. Depending on if conditions are meet, if I just used enough pressure to stop the car, auto start/stop wouldn’t engage. If I press a little harder on the pedal then it would engage. Try pushing the pedal a litter further after you come to a complete stop.

No offense, but this is one feature that would make me not buy a vehicle, I know you can turn it off, but in reality, there hardest thing you do to your engine is start it. All the torque coming from the end of the crankshaft, not all the pistons pushing down in line with the crank. Auto start and stop is a stop to the purchase for me

I’ve had that same issue where infotainment goes black once in a while and then randomly comes back . It is annoying . Also had same thing where the radio stays playing once in a while after trucks been turned off for a long time Maybe 5-10 mins . It is really odd Maybe they have a update for this idk

When I took my truck in for service in December, the dealership performed an update that seemed to help with the "No Content Available" error, and I had read there GM released a f/w update late last year. I am pretty sure that will help you with your issue, but it sounds like you have the same blanking out issue that I do after having mine updated. Mine JUST STARTED the radio playing on after open ing the driver side door, to which I will have them look at the next time I take it in. Never had so many issues with a single Chevy in my life. I am so glad my '57 Chevy is low tech...

I am going to try that today and see if it works.

That might be true for you, but would you take your air conditioner out because of the additional wear and tear on your cooling system? The auto start/stop is a feature that when the vehicle is purchased was an added cost to the base price. As you stated, it can be turned off, but for a brand new vehicle EVERYTHING should work whether I want to use it or not. The liabilities or benefits of a feature should be MY choice, not GM's.

Understand completely, if it was on my truck, I would want it working because it's supposed to.
