I will definitely post here if I ever find a fix for the vibration. My Tahoe has had this issue since new and I assume the problem won't be diagnosed until something in the engine finally breaks.

I noticed after a heavy rain that water was pooling up in the trough under the front portion of the sunroof. The dealership told me that this is normal. I have a hard time believing that this is normal. I asked them to replace the rubber seal on the top of the sunroof and they wouldn't do...

No, my issue is a vibration or shudder when the truck is at idle in park or drive. It's not something I hear.....I can feel it. The RPM doesn't jump around at idle. It happens regardless of the load I have on the electrical system (A/C, etc.). My contention is that the truck simply idles at...

I first posted here 2.5 years ago shortly after buying my 2013 Tahoe LTZ. After almost three years and countless visits to the dealership, I'm no closer to solving the problem. It's been frustrating and honestly makes me want to offload the vehicle before the factory warranty expires. For...

Unfortunately, no solution for mine. I gave up fighting with the dealership a while ago. They refused to budge on the idea that it is normal. They keep pushing a service bulletin in my face that says that "some" vibration at idle is normal. This is the quality that you get when spending over...

I bought mine new and just passed the one year mark (12K miles). I've had it in to the dealership 4 or 5 times for the idle issue. They've checked the motor mounts and ran several diagnostic checks. I've been told that it's normal and was even given a GM Service Bulletin describing the issue...

I have a 2013 Tahoe and have not had this issue (yet). However, I have had several others. I am an extremely disappointed owner so far. No matter what the issue, the dealership always tells me that it's normal and not a problem. The engine vibrates at idle.....normal. The drivers window...

My 2013 Tahoe has had a shudder and vibration at idle since new. I have had it into the dealership more times than I can count and every time I get the same response. I’m told it’s normal and that some of these engines have a slight vibration at idle. I was also given a SB stating that...

What do you guys use to clean and polish your wheels? Despite frequent washing, I have mag/chloride damage from the Colorado winter. I keep hearing conflicting information on the best way to clean the polished aluminum. The wheels are less than one year old so they are not damaged beyond repair...

I know exactly what you’re talking about. I noticed my 2013 Tahoe sat about 3/4 to 1 1/4 inch lower on the driver’s side. The dealership ended up replacing both front suspension coils. They told me the driver’s side coil spring was bad. They claim that it must have been a defective...

Over the weekend I had the opportunity to drive my Tahoe in the mountains west of Denver for the first time since I purchased it. The outside air temperature was 78F and after driving for about 20 minutes the transmission temperature hit 211 degrees. There were some light up hill grades but...

This is a great question and one that I’ve also been trying to answer. I’ve read the owner’s manual and it states that the normal operating range is 180-200. I have a brand new 2013 Tahoe with the heavy duty towing package (with the added external cooler) and often hit transmission...

I understand your frustration with the dealer and the “no code, no problems†attitude. My 2013 Tahoe with 3800 miles vibrates and shakes at idle. I’ve had it in several times to 3 different dealers and they refuse to acknowledge the problem. They run a quick diagnostic check and tell me...

Still trying to understand transmission temperatures if there are any transmission experts out there. Today I hit the highest temperature I've seen yet (194 degrees F). I was in heavy stop and go traffic for about an hour and averaging 10 MPH. Not crazy high for such a low speed HOWEVER it...

Does anyone pay attention to their transmission temperature during normal city driving (non -towing)? I noticed mine hit 189 F during normal city driving after about 30 min with an outside air temperature of 72 degrees. I’ve been told that normal temperatures for this engine are between...
