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.

We just had to spend $1,000 to have the radiator replaced on our 2018 Chevrolet Tahoe because it was leaking which only has 32,050 miles on it. The Tahoe had a 3 year 36,000 mile bumper to bumper warranty, but we were two (2) days past the 3 year mark so they would not cover it. The Tahoe also has a 5 year 60,000 powertrain warranty, but the dealership said that the radiator is not considered to be part of the power train only the hoses going from the radiator to the engine were covered under the powertrain warranty. In January 2019 GM issued service bulletin pi1513F (attached) for 2015-2016 Tahoe for this exact same leaking radiator issue which states that the radiator replacement should be covered under the power train warranty. This is a known issue for 2017 & 2018 models also, but GM has not issued a recall, nor will they cover the 2017-2018 model under the 5 year 60,000 mile power train warranty like they do with the 2015-2016 models.
