    Purchased brand new Chevy 2018 Tahoe in April 2019. Overall good car never had any issues until 02/08/23 as I was driving a got a service alert "Trailer Brake System", It was so random since we have not hauled anything for that to even become a problem. The next day 2/09/23 the car was not drivable it wouldn't turn on it kept giving me the same alert "Trailer Brake System". I called the dealership and they said it's a defect and have to take the Tahoe in for service since only they can find the defected harness and now I have to pay out of pocket for something that I did nothing wrong, something that is manufacture defect and completely unsafe to drive.

    Just driving down the freeway and my sunroof just shattered. We were not driving under anything for something to be thrown or fall on the sunroof and nothing was thrown up from the road.

    While driving home, the the FAC, forward automatic crash, indicator light came on, I applied the brakes and watched to my dismay as my vehicle slowed down but would not stop. I applied steady hard pressure until impact with another vehicle in front of me. The FAB, forward automatic braking system never kicked in. I will contact the dealer concerning the above issue.

    A lifter collapsed, which in turn damaged the lobes of a piston, which then damaged the camshaft...generating a repair bill of $7,100 per the dealer. The vehicle only has 69,200 miles on it. When the lifter failed, the car shuddered at stops, lost some power and made a noticeable clanking noise. When pulling out from stops, or into traffic, the car hesitated somewhat before accelerating. This creates a very dangerous situation. Also, if more lifters or the camshaft seized up at higher speeds, a driver could experience a potentially fatal situation from an uncontrollable vehicle or a fire. Research shows that Chevy/GM knew about the lifter problem on 5.3 ltr engines with their AFM system for years and sold them anyway. They apparently have never solved the problem, and it still exists today. Several class action lawsuits have been lodged against them for the lifter failure problem. Aside from the serious potential safety issues, an expensive vehicle like my Tahoe should not be expected to incur a $7,100 repair bill when it's only 4 years old and has less then 70,000 miles on it. That's ridiculous. My wife and I are both retired. We will be tapping our retirement account to pay for this shoddy Chevy product and will worry that it just might occur again, after the fix. From a safety standpoint, a stall, loss of power, or engine seizure at speed will tax our quick response reflexes. The known lifter problem is a legitimate safety situation and needs to be addressed before someone is seriously injured or killed...if they haven't already. Thank you for listening.

    On July 29, 2022 my Tahoe broke down on me while driving home from work. It started to lose speed while on a busy highway during rush hour. I started losing speed and I kept giving it gas and it wouldn’t go. I kept trying to get speed to try and get off the highway to avoid getting into an accident or put someone else in danger. Somehow I managed to get off into a shopping center. I had come up to a stop sign and couldn’t even get the Tahoe to stop while there was a lot of traffic in the shopping center as well. I eventually got it to a safe spot and called a tow truck. I live almost an hour from home. The shop the Tahoe was towed too said the torque converter was contaminated with metal shavings that was caused by parts on the Tahoe grinding together and therefore contaminating the torque converter and then it ruined my transmission. I was also told this is a common thing they are seeing with Chevy Tahoes, but yet no recalls have been issued and I think something needs to be down about it. It put my life in danger as well as other drivers around me! And I couldn’t afford to fix it so I lost my vehicle and all the hard work and money I put into paying my vehicle since 2018! I also found a lawsuit regarding this issue too.

    When applying the brakes the SUV will pull hard to the left or at times to the right. I get a screen message that reads " trailer brake system failure". The SUV has never trailed anything. Also dont know if these are tied together but I'm also experiencing a dragging battery during this time. When the trailer brake says failure goes away the battery issue goes away. I've done some research and have found a GM service call "N192261050" which seems to indicate the same issue/concern.

    I have a 2018 Chevrolet Tahoe. Today, while I was pulling out of the Sam's Club parking lot I heard a huge thud, the car jerked forward and completely stopped. The drive line / drive shaft had broken clean off. I'm awaiting official diagnosis from Riverton Chevrolet's service dept., but it was a very scary situation. I'm thankful that I was not rear ended or hurt. I see that welding issues are part of a NHTSA safety issue on later model Chevy Tahoe vehicles. I'm wondering if my 2018 is a victim of a similar problem. I do not drive at high speeds or go off-roading. I get my car serviced regularly. This could have been catastrophic if I'd been on the freeway. Repair invoice pending.
