General Motors has issued a technical service bulletin to address a minor issue with the front daytime running lights on certain 2021 Chevy Tahoe and Chevy Suburban full-size SUVs.
The GM TSB document sent to dealerships says that “certain 2021 model-year Chevrolet Suburban and Tahoe vehicles may have a condition in which the daytime running lamps may shift to a bluer shade of white in its lit appearance. The document also indicates that this bluer light color will “remain in effect until the headlamp cools.”
In order to remedy this problem, Chevy dealerships have been instructed to replace both the front left and front right LED driver module assemblies. These repairs will take about one hour for a certified GM service department to complete. This fix requires one replacement part to fix, the “Module ASM – Headlamp LED Driver” (Part No. 84551653) although two of these parts are required for either front DRL.
GM says that all vehicles affected by this problem that are in dealer inventory “must be held and not delivered to customers, dealer traded, or used for demonstration purposes until the repair contained in this bulletin has been performed on the vehicle.” It’s not clear how many vehicles are affected by the issue. A decent number of 2021 Chevy Tahoe and Chevy Suburban models will still be on dealership lots, as the full-size SUVs only began rolling off the line at the GM Arlington Assembly plant in Texas relatively recently.
The 2021 Chevy Tahoe and Suburban represent the next-generation of the long-running Chevy SUVs as ride on a new T1 platform with independent rear suspension. A naturally aspirated 5.3L V8 L84 gas engine comes standard in the SUVs, which is paired with a GM 10-speed automatic transmission and standard rear-wheel drive or available four-wheel drive.

I was about to ask this. The DRLs look horrible when they’re at that stage
I ordered a 2021 z71 Tahoe and finally accepted delivery on Oct16,2021. I was unaware it wouldn’t have a DVD player or CD player. Yes I guess I’m old school but that’s not a big deal. Get everything thru the cell phone. My biggest complaint is there are no sun visor extensions. I am 5’4” and it drives me crazy when the sun is sneaking thru the little cracks. A few other things to notice before you purchase a new Tahoe is the head rests on all 3 rows. The front seats are thick but the 2nd row is thinner and the 3rd row headrest are even thinner. I feel after a some time of exiting and entering on the driver side the side of the seat will be worn out. The seats seat to be cheaply made. It will rub on the plastic that surrounds the bottom. This is my 2nd Tahoe and the seat was made nothing like the new 2021 seats. The steering wheel seems to be not as thick which I like a thicker steering wheel to grip. I’m still figuring out the buttons instead of a gearshift on the steering column or console. Please don’t take this as a complaint just a few of the things I didn’t even think about.
I have had nothing but problems with my 2021 tahoe I wish some one at gm would do there jobs and address these issues I am looking to trade in for a ford
I will never buy another Tahoe! The dealership sucks, (Mountainview Chevrolet, Upland Ca.) at 32000 miles I have had the entertainment, GPS, mag lev shocks, a/c compressor, rear hatch motor, and battery replaced. Tires had to be replaced at 20,000 they were so cheap they wore out fast. 2016 LTZ….GM has given up on good engineering and lacks quality components. For the price of these units its false economy and lots of service. I have had multiple Tahoes, in fact I trade them in at 30,000 miles, about every two years…all LTZ’s but no more! Over 10,000 dollars in repairs in this year alone! Holy Toledo!!! Back to imports again, sorry GM, YOU FLUNKED!! No interest in buying your products again. As a note, also own a 2016 Impala LTZ…..more issues with it as well.
I bought a 2015 Tahoe LT, I believe that’s when they changed the design on them.Started having problems right from the get go.Bad fuel injectors, brakes, steering, magnetic air shocks,motor mount, a.c. system, transmission, flickering dome lights, rear window defroster, front window motors,side moldings,peeling on the instrument panel, this are just some of the things I can remember right now.I paid over $55,000 dollars for basically a piece of junk put together. Chevy will never get another dollar from me for another vehicle. I bought it because supposedly it was supposed to be dependable long lasting SUV. Well if depending on these trucks breaking down, they got that right.Extremely upset.
God gave us Lexus for a reason, sports fans…
