Tahoe LT 5.3L V8

  • Automatic transmission
  • 150,000 miles

A D V E R T I S E M E N T S

10/8/22. Two weeks earlier I began to notice a whining noise coming from what I thought was the engine at that time. I searched and even listen to the a/c, alternator, and power steering to see if the noise was coming from some component of the engine. Then I thought maybe it was an engine lubrication problem, so I got an oil change when I still had 40% of engine oil life left on the previous oil change. I went so far as to order almost $500 in engine maintenance parts (plugs, wires, coils, and fuel injectors). After exhausting all my options, I continue to drive and figured that eventually, the problem would present itself as a failure or some other problem.

Well a day later, it did. While driving in heavy traffic on the way home, it felt as though I was loosing horsepower, almost as if the engine was failing. Once I got off the highway, I came to a stop light and attempted to move forward when the light changed, only to find that the transmission would not engage and accelerating only revved the engine before it finally engage the transmission and pulled forward. Every time I stopped at a light, it seem to get worse. Talk about a real pain in the ass for me and the drivers behind me!!!

Tahoe LS 5.3L

  • Automatic transmission
  • 4,987 miles

This hard kick from the transmission into first gear after a complete stop at stop sign started in around the middle of January. It also shift into Neutral when starting into 2nd or third gear from a slow start at traffic light. When this happens, the SUV slows down and the RPMs and engine revving up to about 4000RPM. Luckily no ones hit my SUV from behind yet. I have to let off the gas pedal and then wait for the RPM to roll back down to about 1000RPM before the transmission catches the car move again. I still have some jerking motion from the transmission trying to find a correct gear.

I took my brand new 2015 Tahoe to my dealer and told them about the transmission slipping problem. I left it over night with them, they said they could not get any code or feel any problem. I took the SUV back and it happen again each day once of twice on my 30miles round trip commute on regular city streets in Dallas, TX. I tried shifting it into the Manual transmission mode to see if it would help. It does not help, I still feel the transmission disengage and engage with some slippage.

Today Feb 8, 2016 it gotten really bad. I had my son in the SUV this afternoon, we stopped at a red light. I feel the transmission shifted while I was one the brake. It acted like it shifted to park when I give it some gas. The SUV did not roll or kick forward like to other time. It just sit there at the intersection on a green light. I had to move the shift level to PARK and then move it to drive before the Tahoe did a hard kick, similar to popping a clutch on a stick shift. It also do not want to back up when I put it in reverse. It finally kick into reverse hard. Luckily I had a fast reaction to catch the brake before it hit my garage.

I am bringing it back to the Reliable Chevrolet dealer in Richardson, TX to have them repair it. I am afraid to drive it now. It could kick into park while I am driving down the street. This will for sure cause an accident. I am thinking of a way to report this major problem to the NHTSA http://www.nhtsa.gov/ and then go onto Twitter and Facebook to tell the CEO of GM to stop allow their employee to make crap car. I have two ACURA MDXs and they don't have any problem. The 2003 MDX got airbags recalls.

Update from Mar 14, 2016: The dealer service department now acknowledge that there is a problem. They had authorization from GM to replace bad gear 3,4,5,6 and reverse, some clutches, a main input rod to the transmission. The dealer service advisor told me that the input rod broke. I asked, how can such a heavy duty rod on the heavy duty SUV that supposed to be able to tow 8500lbs can be broken? They don't have but a speculation answer, that it was a bad part. Why didn't GM warranty gave authorization to replace a new transmission, but decided to throw good money after bad? That person at GM should be fired. I got my Tahoe back after about two weeks in the shop. The dealer spent 120hrs of labor on the work. GM had wasted so much of my time. The Tahoe started acting up the day after I got this back. It has gotten worse as I attempt to drive it some more. I brought it back to the dealer and they drove it hard and told me that can not find anything wrong. This is the same line that this dealer told me the first time I brought my Tahoe in for repair. All of that work short of replacing the transmission the way that they should have done. Now as of March 4, 2016 the transmission shift to neutral and the engine races up the RPM on normal side street driving. At times it does a hard shift driving around 25-45mile per hour. It feels like a clutch popping when you drive a standard and pop the clutch. This Tahoe got an automatic transmission. I believe the 2016 Tahoe also uses the same transmission as the 2015. I am still complaining to GM Warranty to fix this safety problem. They are giving me the run around and not want to make me whole. If this was a TV, I would have dump it at the dealer and get me money back. I didn't buy this SUV to pick a fight with GM warranty for fun or put my family at risk. Enough said here for now. This problem is so weird and I feel like I am a beta tester for GM on this Tahoe. It is a lemon, but GM don't want to admit it. Oh they also tried to close my case when they call me twice while I was not able to take the call because I was on vacation on a ship.

Tahoe LTZ

  • Automatic transmission

When you turn car off and the car is in drive the transmission disengages and the car can roll. Very dangerous situation. The car should have a safety feature that prevents you from turning off car until you put in in park.
