2023 RF Turn Signal

2023 Silverado Z71 RST 5.3L. 

 

So my right front turn signal started to go through a cycle where it flashes three times normally then goes into fast flash.  During fast flash there is no light as seen from the outside (not working).  The indication on the dash is "Check Right Front Turn Signal"

 

After restarting the truck and it is now no longer an issue.  I was ready to change a burned out bulb...but apparently that's not the cause.

 

What would cause this as I am not convinced anything can fix itself?

 

Thanks

Could be a shorted bulb or an intermittant. The quickest and easiest thing to do is to replace the bulb and inspect the connection if you can replace the bulb on your RST. Replacing the bulb on my Custom is hard to reach.

Pretty much same here.  Feels like I need to fix something, however I did find it that the turn signals are controlled by the BCS so maybe something just reset itself??

So you scanned it and found nothing. Restarted it and it worked.

This is somewhat of a common occurrence at the moment.  2022.5 and 2023 1/2 ton and 2024 HD with the full LED headlights.  GM has been finding it to be something simple as the headlight needs to be unplugged and plugged back in, or its been replacing the affected headlight assembly or wiring terminal issues at a different connector point in the truck.

 

We've had 3 trucks do this.  Two of them was just a headlight connection issue, the third one got a new headlight assembly.  All 3 trucks it was the right front.

Loose connection can cause intermittent fault. 

 

Connector not fully snapped together.

Pin not fully seated in connector. 

'Cold' solder joint

I think the odd part of this is that it shows a a failure upon the first right turn of the day and doesnt "fix itself"  while the truck is running.  Shutting the truck down and restarting will limmediately fix the issue and it stays "fixed"  during driving until the next time. Hard to believe a bad connection would behave this way....but maybe it does.

As a follow up to this...... the dealer replaced the multi- function switch (assuming its the turn signal stalk on the left) and it hasnt happened since.

So i had my 2022.5 at the dealers today for a faulty right side headlight. The dealer did a reflash and said that it fixed the issue. Me in a rush to get home didn't check it a the dealer and when i got home it didn't work so now i am waiting for a headlight assembly from GM and according to them it's on a nationwide backorder!  Has anyone been able to figure out what is causing these issues? I am concerned with driving at night because cops are just looking for an excuse to pull people over and of course it's a safety issue as well.

      Another 6.2L engine failure!

      By KARNUT · Posted

      More is cylinder deactivation. Kia-Hyundai Ive had 4. The warranty is the same 10 years 100K miles. My grandson drives the first one 05 Elantra GT. My wife drives the second one 2011 Genesis. The Genesis still performs as new and looks great. The Elantra looks rough. He’s not kind to it. The third was a Genesis coup. The fourth was a Santa Fe. Those were my daily drivers. I don’t keep them long. Kia is the same as Hyundai with the same warranty. I looked at the K-4 today. Too small, otherwise pretty good buy. Most of Hyundai and Kia’s have a performance upgrade.

      Oil Consumption

      By Grumpy Bear · Posted

      Great question. Answer....depends. One the volume of the crankcase, the driver that will actually be using the vehicle and the amount it uses plus the distance expected for that next trip. Couple of for instances:   Wife is going to drive Dizzy to Moline and back plus a bit around town so say 500 miles on the day. I know from years with that SUV that around town and local rural it uses about a quart in 1250 miles. But on the Interstate and her at the wheel without her anchor nagging her she'll push it and it will drop a quart in about 800 miles. Hence, around town I wait to somewhere between a quarter down to a quart down. On her trip I'd top it if it was down a few ounces and hope for the best.    Have I overfilled one? You mean by adding before it needs a full quart I assume. No, not once after finding the true fill mark.  I know the dipsticks of everything I drive and add what it needs. I learn this by doing the first oil change a quart low. Run the motor for a few minutes. Let it sit over night. Check and mark. Then add half a cup at a time making note of the place on the stick. I add through the dipstick tube with a barbeque basting bottle. Give it a few minutes to drain down and check again.    A vehicle like Dizzy that uses this much oil will take a few quarts between 3K changes. I keep one in the vehicle with the bottle and a bag. (Mindful of it's fullness) Not a big deal and never makes a mess of it. There is no such thing as "multiple quarts' in my shop for any specific oil. There will be a maximum however of the number of different oils used over the fleet.     Dizzy holds a nominal 5 quarts. So the first fill was indeed over as it actually took 4.75. My vehicles are fit with Valvomax valves so I can meter an ounce on the drain if need be. Found her mark first crack at it. Never to be repeated.    Pepper uses none between changes so I don't keep a quart in that one. Straight up 6 quarts put her dead on the full line. Check it ever fuel stop. They will surprise you when they start using.    Raven holds 3 liters or 5.44 ounces over three quarts. I add 3 quarts and 6 ounces. That gives me 5 oil changes on my orphan quart.    Lawnmower holds about 3/5 of a quart. I don't over fill it to prevent an orphan. So yea, depends.

      185k on original 6.2L engine and 10 speed. 6" lift with 35" tires. Changed oil (Mobil 1 synthetic) when truck told me to. Original tranny with original fluid and no service or flush done. All highway miles. A/C compressor replaced at 155k. Oil cooler line replaced at 180k. Still daily driver. Love this truck.   This is my 3rd 6.2L vehicle (2008 Yukon Denali / 2018 Cadillac Escalade) with over 150k miles and no issues. Denali had broken motor mount at 100k.
