    21' Suburban HC - Electronics went bananas.

    Diffidently time to update this thread. The issues I was dealing with before, e.g. error codes, infotainment system no longer functional, etc. remained the same. It took almost 1 1/2 months to get into my local dealer, and then the truck sat at the dealer for another week before even being...

    21' Suburban HC - Electronics went bananas.

    Unfortunately, no success. As for the safe mode; you can't get into that feature without having access to the UI. My infotainment system is dead, no power, no response.

    21' Suburban HC - Electronics went bananas.

    Thanks. Solid voltage at both the battery (new) and at the OBD port. Also checked each of the 3 leads coming off the positive battery terminal, both with engine off and on, to check the alternator. All solid readings. Though the lead contacts were clean, gave a additional clean none the less...

    21' Suburban HC - Electronics went bananas.

    I gave it a go, no dice. Unfortunately. There's two others in the area; however their reviews are abysmal.

    21' Suburban HC - Electronics went bananas.

    Yea, this may be the case.. but given I can't get into service till mid-December, was seeking alternative resolutions.

    21' Suburban HC - Electronics went bananas.

    Thanks. At this point, the Infotainment system does not power on. The physical buttons below, as you mentioned, power, home, skip, etc. Do not function either, nor do they illuminate. I've pressed every reset combo on those buttons I could find without success. As for the indicator/blinker...

    21' Suburban HC - Electronics went bananas.

    Hey All, I figured I'd drop a note here just in case someone else had gone through this issue and worked through to resolution. Unfortunately, my local Chevy dealer's service department is way behind, earliest I can get in is almost a month out. my truck: 2021 Suburban HC 6.2L What happened...

    Corsa Exhaust for 6.2 Rear Alignment Issue

    Installed the new Y-pipe and passenger tailpipe. It’s as close to perfect as it’s gonna get. Much better alignment. The passenger side pipe still pushing more outside than driver but I can live with it. No longer has that droopy/poorly hung look and no longer almost touching the facia. Very...

    Corsa Exhaust for 6.2 Rear Alignment Issue

    Not sure what the exact build date was but I ordered and received mine in the second week of February ‘23. Considering that Corsa are generally built to order I’m guessing it was made in Jan/Feb.

    Corsa Exhaust for 6.2 Rear Alignment Issue

    Update: I contacted Corsa/TMG via the warranty form. Took a bit to get a response but recently heard back. According to TMG, they’ve received other complaints from shops installing this model exhaust with the same issue. They’re going to send me a new Y-pipe and passenger tail pipe. Excellent...

    ERA 2K Caliper Paint.. Great finish!

    Decided to hold off on the replacing the fronts 4-pots with the GM/Brembo 6 pot kit... but decided to paint the front calipers. I've typically used brush-on but decided to give ERA 2K spray paint a try, gotta say, they really nailed the STOPTECH-like red coloration. The finish is also excellent...

    Corsa Exhaust for 6.2 Rear Alignment Issue

    Thank you. Looks very similar I guess. Hmm. I'm beginning to think so... Upon closer look at the photo on the Corsa site (I should I looked closer but figured it was a tip fitment issue). It also looks pushed out, yet the rear tip alignments had me thrown off.

    Corsa Exhaust for 6.2 Rear Alignment Issue

    Hello All, For the Corsa owners with a 6.2 and dual rear exhaust. I've had the Corsa for going on for about a month, love it. However, I don't like the way the tips align in the rear facia. No matter what I do, I can't seem to get them centered in the rear facia cutouts, e.g. I can't bend them...

    2021 Tahoe wireless CarPlay not working

    Right, it's not intuitive that the iOS device is making a WiFi connection to the vehicle when connecting to wireless CarPlay. However, when it connects, you'll see on your iPhone that the WiFi icon/connection is in-use, it'll be greyed out. If you attempt to "enable" WiFi on the iPhone, it'll...

    New shoes.. Ferrada FT1 in Brushed Cobre (Bronze)

    Finally got around to getting some new wheels. Went with the 24x10 Ferrada FT1 in Brushed Cobre. Decided to go a bit different, was a bit nervous as its really hard to tell the shade of bronze based on internet photos but love it so far especially when the sun hits them. The color very closely...

    2021 Tahoe wireless CarPlay not working

    By any chance is your in vehicle WiFi hot spot disabled? I noticed the other day in my 21’ Suburban that if I disabled hotspot, wireless CarPlay will also stop working. I disabled the hotspot as I don’t use it for connectivity but it’s clearly a dependency for wireless CarPlay to work. I’m kind...

    Corsa catback 6.2 Yukon XL AT4

    Well... I did the install this past Friday, no stands or ramps. It was tight on the side, especially trying to lift the muffler drum section into place, it slipped once, busted my lower lip... install battle wound. Were you able to torque to spec the clamp on the connection point above the rear...

    Corsa catback 6.2 Yukon XL AT4

    Yep, I believe the Borla one is #19433763, the parts description even mentions Borla. I was referring to the other 6.2L GM exhaust, #84888292.

    Ultimate RSE (Rear Seat Entertainment) Setup!

    Is the older Seagate a HDD spinner using USB-A? If so it may be adding to the slowness of the indexing that the system is doing. I've never seen an indexing notification on either my front display or the rears. I do, sometimes, need to unplug and replug the flash drive after starting the truck...

    Splash Guards with Powered Running Boards

    Weathertech, as mentioned. Installed them yesterday. Had them on my 2016 Tahoe and they did an amazing job keeping the spray and kickup to a minimal.

    Corsa catback 6.2 Yukon XL AT4

    Sounds awesome. Mine arrives today...pumped. Some quality time under a 7000lbs truck on jackstands. What's interesting, if you look at the GM Performance Cat-Back #84888292, looks VERY similar to a rebranded Corsa. Spidey sense says it is.
