TIRES, TIRES:SIDEWALL, TIRES:TREAD/BELT
LT275 65 R18 123/120 R DOT 1 BE BP AT 21 My daughter has pictures of the tires, all four tires (all bought at the same time) 05/6/23 from Discount Tire, are splitting along the side wall, originating at the tread line, we have talked with Discount tire, there are 40,000 miles approximately on the tires. They have been appropriately rotated and balanced. There have been no repairs of the tires. This is noted to be a defect, not normal wear and tear of the tire, per Discount Tire. They have offered 423.00 credit to purchase new, and have come back with 50% off new tires. Since this is a defect, verse actual wear and tear I do not believe that is appropriate. 75-100% of the replacement value. The tires should reasonably last between 5-6 years. The defect increases the risk of a blow out on any one or several of the tires. Discount Tire in Lubbock has confirmed that there is an issue, but I am not happy with their resolution.

ENGINE, POWER TRAIN, UNKNOWN OR OTHER
Out of nowhere without any warning light all of a sudden couldn’t back up when geared into reverse to reverse. Turned the vehicle off and back on, then was able to reverse. Left parking lot and was on the road and vehicle started loosing speed, then put into park with hazard lights. When attempting to get off the road for safety reasons tried putting into drive and the car then drove in reverse. Local Fire department came and called in the local police dept for assistance and pushed vehicle off to the side and tow company came and took to the auto shop with information today of the transmission going out, and with that causing happening causing the Fluid to Smell Burnt and Full. The auto shop test Drove and made It 30 Feet and Would Not Move. Transmission Is Failing and Causing the Concern.

STRUCTURE:BODY
EVERYTIME IT RAINS REALLY HARD, MY DRIVERS SIDE B PILLAR WHERE THE HANDLE AND SEAT BELT IS, IS SOAK AND WET FROM A LEAK. THIS HAPPENS ALL THE TIME. I HAVE HAD MY SUNROOF CHECKED, MY WINDSHIELD CHECKED AND DRAIN TUBES CHECKED. THERE IS NEVER ANY WATER OR WETNESS ON THE FLOOR, ITS ONLY THE HEADLINER. THIS HAS BEEN AN ON-GOING ISSUE. I HAVE BEEN INVESTIGATING IF THERE ARE OTHER TAHOES DOING THE SAME AND YES THERE ARE AND 1 HAD WENT TO A BODY SHOP AND THEY FOUND OUT THAT THE MANUFACTURER WELDS WERE NOT WELDED CORRECTLY, WHICH CAUSES WATER TO GET INTO THE ROOF. THIS CAN CAUSE MOLD AND EVENTUALLY OTHER ISSUES. IT HAS STAINED MY HEADLINER. SOMETHING NEEDS TO BE DONE ABOUT THIS BECAUSE I CANNOT AFFORD TO HAVE A BODY SHOP FIX THIS KIND OF REPAIR AND I SHOULD NOT HAVE TO FOR AS MUCH MONEY AS I HAVE PAID FOR THIS VEHICLE. I HAVE VERY YOUNG GRANDKIDS THAT RIDE IN THIS VEHICLE AND ONE HAS VERY BAD ALLERGIES AGAINST MOLD. AND IT IS NOT FAIR THAT I EVENTUALLY WILL HAVE TO GET THIS FIXED BECAUSE IT WILL ALSO CAUSE RUST. PLEASE DO SOMETHING ABOUT THIS.

UNKNOWN OR OTHER
WHEN IT RAINS REALLY HARD, THE ROOF IN THE B PILLAR LEAKS ABOVE THE SEAT BELT AREA INTO THE HEADLINER. MY HUSBAND WHO IS AN AUTOBODY TECHNICIAN HAS MADE SURE MY SUNROOF LINES ARE CLEAR AND THE WINDSHIELD MOLDINGS AND SEALS ARE GOOD. HE HAD ANOTHER ONE AT HIS PLACE OF EMPLOYMENT WITH THE SAME ISSUE AND IT WAS THE ROOF WELDS, WHICH ARE DONE BY THE MANUFACTURER. I AM HEARING MORE AND MORE TAHOE OWNERS WITH THIS SAME PROBLEM. AS MUCH AS THESE VEHICLES COSTS US, THIS SHOULD NOT BE HAPPENING. THIS CAUSES MOLD IN THE ROOF AND RUSTING. THIS HAS TO BE LOOKED INTO BECAUSE THIS IS AN EXPENSIVE REPAIR IF I NEED TO HAVE THIS PROBLEM FIXED AND COULD ALSO CAUSE HEALTH ISSUES IF NOT ADDRESSED WITH THE MOLD.

UNKNOWN OR OTHER
The rear AC evaporator located behind the paneling in the rear of the vehicle was leaking AC freon r-1234yf. This was diagnosed after a weeks long troubleshooting by my mechanic trying to find the leak in the rear AC lines causing the vehicle to fail the vacuum test. After he showed me the part and where the cracks were, he suggested I report this as a safety issue since the coolant was leaking inside the car and is highly flammable. He also said he has had many other GM vehicles with the same issue and thought a recall should be issued.

The clear coat has completely failed on mainly the hood and roof of the entire vehicle. Each of the sides have lost a good amount of shine too but there hood and roof are a compete different color compared to the rest of the Tahoe. The paint is the pewter/grey so it is extremely noticeable and very much an eyesore.

ENGINE
During a road trip, we came to a stop and upon stepping on gas to proceed on the road and it wouldn't go. The engine revved and "pulled" until we were able to move. We took it to a dealership as well as private mechanic and was told it is an engine problem and running $3k or more to have it fixed. We have small children and consider this a safety hazard. Unfortunately, this is the only vehicle we have to commute.

ENGINE
Was driving approximately 45MPH and the truck just slowly powered down and "Engine Power Reduced" and eventually cut off and wouldn't crank back up. Got it towed to the Chevrolet dealership and was told the engine has to be replaced due to the bottom of the motor and the crankshaft in cylinder one. Was told it would be 17k to repair it.

ENGINE
For several months my check engine light has been flashing when I’m driving, especially on the highway. At times my vehicle feels sluggish. I press further own into the gas pedal and I am not getting adequate propulsion. It also feels like this when I’m going up a hill. I brought the vehicle to two independent service centers to get a diagnostic. One indicated getting misfire readings on two cylinders. The other indicated getting misfire readings in three cylinders. As you would imagine this is an extremely concerning safety risk.

UNKNOWN OR OTHER
Roof racks have deteriorated due to sun exposure and have cracked where the contact the top and started leaking. The paint on the roof and hood had also failed. I had to have the top and hood repainted prior to having it ceramic coated. The roof racks leaking have damaged the headliner in the cargo area. I have tried to reseal them with a silicone sealant since removing them or replacing them is too expensive and would require removing the entire headliner to access the connecting bolts.
