Used Chevrolet Tahoe For Sale

I bought this LS 2015 Tahoe new in Sept 2015. I thought this Tahoe would give me confidence and safety on the road in Dallas, TX. I really like the SUV in the first 3K miles or so. I took it easy on the SUV in breaking it in. In the first couple of weeks after I got it from Reliable Chevrolet in Richardson, TX the driver door rattles. I took it back in and the dealer fixed in the same day. But this shouldn't happened in the first place on such an expensive SUV. I own two Acura MDXs, but wanted a bigger truck for towing of a boat in the near future. At around 3K-4K miles I noticed that the SUV make a "clunk" metallic sounds intermittently when I stop and start at stop sign. It also started to shift weird and at times slip into "neutral" after I accelerate at stop light. When this happens the Tahoe lost acceleration and the RPM goes to 3.5-4K. I almost got hit from behind a few times. I had to let of the gas peddle and wait for the RPM to return to about 1K before a gear would catch and the SUV move again. I brought the it in for the dealer to check it out and have the oil change around 4.5K mile. My dealer service advisor told me that they find nothing wrong with the Tahoe. They said there was no code. I told them that I am not wasting my time to bring the SUV in for no reason. I took the SUV back to the dealer after a few days later after I had a close call with my family in the SUV. It came to a stop light on a down hill street and I felt the transmission shift a somewhat weird. When the light turn green, I press the gas peddle lightly to go, but the engine rev-up and RPM go way up to about 4-5K but the Tahoe just sat there. Luckily no one hit me from behind. I had to shift it to park and then shift it back past DRIVE to M1 to get the Tahoe to move. I got home and tried to back it into my garage, it didn't catch a reverse gear to backup. I gave it some gas, it abruptly jerk back and almost slammed into my garage. Upset and scare of drive the Tahoe is an understatement at this point. I took it back to my dealer the next day to have it inspect and fix. The dealer gave me a Traverse for a loaner. I left the Tahoe with them for almost two weeks. They said they had to replace the 3,4,5,6, reverse, and the input rod. The input rod was broken. I looked up this rod, it is a major bar of metal that would take a super force to break. I am not a transmission engineer, but replacing four gears and reverse out of a six gear transmission seems excessive and stupid. They should replace the whole transmission. They still don't know what caused the transmission to wrecked all of those gears and clutch. I am not scare to drive my "safety" SUV. GM is giving me the run around instead of addressing this SAFETY issue. I will have to push a Texas Lemon law soon if GM does not make it right for me. I am tire of being the SAFETY Beta tester for them. When this transmission cause a problem of locking up on an on ramp or in the middle of a high speed slowdown and accelerate on a highway. You can imaging what kind of a wreck that may be. I am sharing my experience with the readers of the website and hope that the new Tahoe potential buyer to consider carefully before buying one. Oh and when GM service rep calls about by issue after I went on social media site and voice my concern about the safety of drive my Tahoe, she always warn me about the call being record. The next time I too will warn them that I will have the conversation record also to see what happen. I will update this post as I work through GM warranty. I will report the good, bad and ugly. Update March 14, 2016 The dealer service department finally acknowledge that there was something wrong with the power train or transmission. I learned that GM warranty controls how the dealer repair the SUV by only authorizing certain fixes. When it was done (repaired, not really) the service advisor at the dealer told me that they had to replace gear 3,4,5,6 and reverse, some cluthes, and an input rod on the transmission. They called it fix and I took the SUV back. Within a couple of days driving it acted up again, very similar to before, slipping into neutral and not shifting out of first and second or third gear. It jsut feel stuck in between gear at time. I finally got in touch with the GM warranty person that I was working with, she told me to take it back to the dealer to let them check it out. I did that what she asked. The dealer kept my SUV for a couple of days and then called to tell me that they cannot find any code or problem. I took it back and drove it to Houston, TX from Dallas, TX on Mach 4, 2016 for vacation. The SUV slip to neutral on the drive down. It does not move forward or reverse while I tried to park the SUV at a hotel parking lot. I had to let of the gas peddle each time and wait for a gear to catch. I have problem with it every time I drive it.
