2021 Tahoe RST Abismal mileage
What, you don't like those craters in between the lanes? They should have signs about changing lanes at your own risk.- revengejr

2021 Tahoe RST Abismal mileage
LOL, the garage sale was this past weekend, sorry. I'm not even 40 yet so we decided not to wait until we were too old to enjoy the better quality of life, lower taxes, and better climate. If it matters, while my wife is from here, I am not so I have no strong ties. Market caused house value to...- revengejr

2021 Tahoe RST Abismal mileage
Agreed and my wife and I feel the same. However, this is a lease but I like to keep my options open to potentially buy it out. I also think we figured out the main issue, lots and lots idling on my wifes part but her not telling me this until like this weekend. See my previous post. Thanks to...- revengejr

2021 Tahoe RST Abismal mileage
Yeah, so my wife and I have been messing around with it and today we took a 10 mile trip on the Northern state toward Huntington and back (since you are clearly a fellow LI guy), computer calculated average MPG at nearly 11 mpg up from 9.8mpg just from about 20 minutes of highway driving. I...- revengejr

Service Safety Restraint System error
Just to update my last post here, I just got back from the dealer to look at this and in-fact this is a known issue from GM. I had them print it out for me. It's in their system as doc id #5651275 and #PIT5774. Apparently the cause "could be a logic lock with the A103 roof console" and according... -
2021 Tahoe RST Abismal mileage
Just got back from the dealer. The service advisor agreed that the mileage was low so they want to do a 1,000 mile test. Basically, come in, do an oil change, top off al fluids and then drive for 1,000 miles. Bring it back, they will check all of the levels, specifically the oil, and see if...- revengejr

2021 Tahoe RST Abismal mileage
@1BADI5 It's a 5.3L not a 6.2. My suburban and older Tahoe had similar engines but we experienced much better mileage - about 15mpg. I don't think this truck has the AFM in it like older models. My old trucks would tell us when it was going from 8 cylinder to 4. I've also see the GM lawsuit...- revengejr

2021 Tahoe RST Abismal mileage
Hi guys, I bought a 21 Tahoe RST back in February. Before that I had an '18 Suburban and before that a '15 Tahoe. My wife likes a new truck every few years and drives primarily in suburbia as a school bus for our kids. Our driving habits have not changed however on this new Tahoe, we have been...- revengejr

Service Safety Restraint System error
Hi guys, so I have a 2021 Tahoe RST with 1,500 miles bought in February. I also had the SRS light come on around 1,200 miles, took it to the dealer for servicing and they found code B1A7A. Reset it and no issues until 1,500 miles. Yesterday, my wife noticed the visor lights not working and on a... -
PWM Sweep Noise when in Auto or 4WD
Thanks for the suggestions and replies. I spoke with the service manager at the dealership today. He suspects, as do I, that if he continues testing this on other Tahoe's (3 so far), the results will be the same. The first course of action they are going to do it contact GM directly to see if...- revengejr

PWM Sweep Noise when in Auto or 4WD
You're not alone. Help! I just posted this on another thread but just saw this. Here is our problem: We just leased a 2015 1/2 Tahoe LT. My wife started complaining of a high pitched noise coming from the dash on the left side but I couldn't hear it. We took it back the dealership and they...- revengejr

Yet another problem: Oil Leak 2015 YD
Doc, we just leased a 2015 1/2 Tahoe LT. My wife started complaining of a high pitched noise coming from the dash on the left side every time she touches the accelerator or immediately after she turns off the ignition but I couldn't hear it. We took it back the dealership and they couldn't hear...- revengejr
