Huge GM Truck Brake Recall Announced by NHTSA - Is Yours On The List?

Recommended Posts

Someone noted that when they sit at a stop light and pump the brake pedal it gets really hard ... uh, isn't it supposed to do this?

 

Just took mine in yesterday ... reprogramming took a couple of minutes.

 

The recall apparently also includes an additional 12,000 miles on the pump warranty.

You've never had the issue.   Talk to us when your brakes go out in a situation like my previous reply.   Consider yourself lucky.

TwoBall - I understand what happened in your circumstance.

 

Another poster had noted his brake pedal got hard when he pumped it at a traffic light ... different circumstance.

This entire recall is BS anyway.   They know the pumps are failing / deteriorating due to sludge buildup, so the fix for that is to just patch the software to run them harder?    What the hell is that?   How does something like that get approved by the NHTSA?  What happens when the pumps get to the point of complete failure?   Pathetic.

I have a 2016 5.3 with 70K and the pump was replaced at 40K which was not covered under warranty and cost $591.  Basically GM will warranty moving but not stopping.  Last month GM sent me a reimbursement check for it.  The problem was at slow speeds; like in stop and go traffic.  It felt like the truck stalled.  I got a notification this morning of the recall.

yup,that really stinks.   this is the way of the of the Automobile these days,all the manufacturers relying on software to fix issues,instead of actually fixing the correct way.   and its not just GM they all do it.

Has anyone went aftermarket? Is there an aftermarket version? Curious if the aftermarket have issues? Does synthetic oil make it last longer? I don’t know much about it so trying to learn for when I get one.

When stopped with the engine idling and I pump the brake or even very low speeds I get the hard brake pedal. It’s like when you pump the brake with the engine off on other vehicles how after a couple pumps it gets hard. I never felt in danger though. Also never had any lights on the dash.

I got a notice in the mail awhile back(months) mentioning this issue, but it said to only take it in if I was seeing that issue. Which I haven't experienced... Yet..

 

Just checked that link and I won as well. Guess I'll be scheduling a visit... 🤷‍♂️

Ya GM already did this in Canada. It’s not a fix. It’s a CYA and shift of liability for GM. All it does is make the earning light come on sooner. Doesn’t make the brakes work any better. In fact I still can’t stop with a trailer on while backing up and no light comes on saying to service the assist.

I see absolutely nothing has changed at GM since I bought my 2007 Silverado off the showroom floor ... 🙄

 

My 33 year old Grand Marquis with 265k miles, and my 26 year old Volvo 940 with 187k miles both have their original brake boosters and master cylinders ... and NO vacuum pump. The Marquis is also on the original calipers ... and fuel pump. 

 

Just sayin' .... quality doesn't have to be this bad!!! 😣

My 2014 only has 50k miles on it, but I called in to get the recall anyway. I change the oil every 3-4k miles and full synthetic but never hurts to be cautious. Thanks to the OP for the heads up.

true,but why cant they build an engine that makes enough vacuum for the power brakes.  were not running some high lift cammed drag car here.

The AFM when engaged reduces the vacuum produced to the point where the power brakes can be ineffective.   That is the reason. 




No. It happens at or just above idle AFM has nothing to do with it.

Windshield wipers stop working it’s that damn AFM lol.
