Engine off at stop

This is my 4th gm product since 2010 and would like to know who's brainstorm it was to have it shut off at stops. Even when I pull into my garage and stop the motor shuts off and when I put it into park it restarts. How much gas is this going to save versus the cost of replacement starters. When I go to the market 4 blocks away and my car restarts 3 times it is a bad idea.

2018 GMC Terrain Transmission blows 1034 miles

I purchased the above vehicle with 134 miles on, brand spanking new. 2 weeks later the transmission blew with 1034 miles on it. I made 3 proposals to GM through the dealer. 1 Replace with new transmission 2. Replace with new car 3. Extend warranty on transmission for the time I own the car. The culprit in this issue was there were METAL FILINGS in the transmission. They did not tear down the entire transmission to see if ithis issue went beyond the area they checked and found the metal FILINGS. I did not buy a brand new UNC TERRAIN to have ISSUES with it. The best GM will do is replace part of the housing and 2 solenoids. Oh, they will also make 1 car payment for me. I did neglect to mention that the reason I bought a new car was because the transmission blew at 150,000 miles on my Nissan Altima. Anyone have suggestions?

AUTO Stop function stop working with no fix.

I bought a 2018 GMC Terrain Denali. Loved it right away. Lots of options for a price that worked with my budget. Then... I was at a stop light and the auto stop function stopped the engine. When I put my foot on the gas - the car would not start again. I was soooooo lucky that the person behind me was paying attention and I did not get rear-ended. The problem is that you cannot get the Terrain shifted into Neutral to move it off the street. Actually, my car wouldn't turn off. The engine wouldn't start but the rest of the car wouldn't turn off. Weird. Had it towed to GMC and they said they had no idea what was wrong - they're words. They kept it for a week and replaced a battery cable. Got it back and drove it for about 3 weeks and the same thing happened. Had it towed to GMC. They kept my car again for a week and this time replaced the starter. GMC actually paid for 1/2 of the starter so obviously there is a problem. Sold the car to the dealership as I was scared to death this was going to keep happening - wish that GMC would've allowed the driver to turn the Auto-Stop function off. Now I feel safe and secure driving my Honda.

Have had to have the vehicle jump-started twice. OnStar monthly diagnostic report keeps stating "LOW BATTERY" "HAVE VEHICLE SERVICED SOON" Been back to the Dealer 5 times. The fourth visit, GM's Business Resource Center had a GM Field Engineer attempt to repair the vehicle but he found that the electrical system was "within specs" He apparently disconnected the battery shutting down all electronic modules to get his "within specs " readings. That was evident when I picked up the vehicle and found that all the pre-set radio stations had disappeared. The dealership has told me several times that GM is aware of the problem and has been working on a solution. They have had other complaints. They have also blamed the cause on "too much electronics." General Motors also sent me a letter after their " Engineer" attempted the repair which stated " Our attempts to contact you to schedule a final repair opportunity have been unsuccessful. Your Final Repair Attempt case is being closed." The letter was apparently an attempt at defending the coming Lemon Law case that I'll be filing. UPDATE: Traded the vehicle with 3.300 miles and only 11 months old. Will never purchase a GM vehicle again. Anyone who purchases a GM vehicle has to be insane. Read Service Bulletin PIC5650C (Available on line at "PIC5650C.com) which alerts dealers to electrical problems in 29 models of all 4 makes of GM from 2018s dating back to 2007. They tell the dealers not to replace any parts and blame the problems on "RFID (RADIO FREQUENCY IDENTIFICATION DEVICES)" that owners bring into the vehicles such as cell phones, chargers or any other device that omits a radio frequency. The last straw for me was GM's recall on their front crash sensing device module " that may not deploy the air bags." All they did was reprogram the module. What ever altered the program so that the air bags would not deploy could just as well alter the reprogramed module when I drove out of the dealership. A proper fix would have been to encase the module in a plastic that would not let the RFID pass through the plastic and alter the module. Such plastics are available but more costly. GM has elected to stay with the cheaper plastic and risk death and serious injury to GM owners and their passengers involved in front end crashes. GENERAL MOTORS HAS BECOME CHINA MOTORS.
