No dealer, nor GM themselves, can afford the lawsuit that would stem from such a situation. They also know that with the tools and technology the general buying public has at their disposal to track a VIN number's history they cannot hide a thing.

GM's corporate compliance department ensures that kind of thing doesn't happen today. That I can guarantee you. Anyone in the chain of command reviewing a lemon buyback repair and resale who even suggests such a thing will be looking for a new job Monday.

THIS!!!

Once a car is lemoned, the title is branded as a lemon. No manufacturer would try to cheat the system today.

Now, that doesn't mean that 3rd parties/used car dealers don't do it. Florida is known as a state where a tainted car and title, can be flushed (albeit illegally) and come out clean at the other end. I would never buy a used car from Florida.

In addition, many lemoned cars are donated to high school or trade school auto mechanics programs, where they spend the rest of their lives being unassembled and reassembled.

I had the brakes fail just like the OP in the fall of 2016. They have not acted up since then but I have less than 6,000 miles on my car now.

Sounds like he's a Mustang owner.

I have not experienced a brake failure, but I did get a "Service Brake Assist" message and brakes would make a strange noise at low speeds but seemed to operate normally. This is the first time I have had any issue with brakes and hopefully the last. Car only has 11000 miles on it.

The issue isn't ABS failing, it's the ABS computer preventing brake pressure from going to the calipers because it believes that the brakes are locked up.

It's basically how ABS works.. in the case of the OP, the ABS computer is misbehaving. From the ABS pump back, yes, brakes are the same as they always have been. But between your foot and the caliper.. it's not.

What? Manufacturer sells lemon vehicles all the time. They attempt to fix it, but that doesn't mean it's fixed.

If you see "Manufacturer Vehicle" on a carfax.. it's pretty much a buyback. When I was looking at used F-250/F-350 trucks I saw 50-60 lemons. Chevy sells them also. Not all titles are marked as a lemon as that varies by state. I found a BUNCH in Florida that were simply transferred down from other states where branding the title is not required. Florida actually does require it to be labeled as a "Manufacturer buy back".

And if you are worried about Florida cars.. avoid Kentucky like the plague! IIRC that's the only state where you can convert a certificate of destuction title back to a normal title. Also illegal of course.

I just experienced this issue and thanks to checking in the forums here had it taken care of with a service bulletin. I understand this is an old forum, but with low mileage cars still out there, this issue is still very real in 2020 and I wanted to help anyone I could.

My brake assist warning came on and I lost about half my braking pressure and it felt that ABS was on 100% of the time. This is mentioned in the owners manual as normal behavior when the service message occurs.

I turned the car on the next day and the issue was gone but took it for service anyway. They told me there was a service bulletin and they will simply run a diagnostic and if no issues are found other than the TSB then that's all they will charge. It happened 8 hours prior the night before the computer had all the error codes stored so they were able to pull them up without any active CEL or Error Codes.

Should be a recall and not a TSB but just needed to share this as these forums are the reason I knew of the fix ahead of time. Maybe a diagnostic fee is worth the piece of mind to get the update needed rather than waiting for the brakes to fail in traffic as mine did.

"Internal software fault in EBCM. Reprogram EBCM per BULL#17-NA-048"

[cellsafemode]

You wont get the error unless it occurs, so diagnostic tests wont save you from experiencing the loss of ability to stop while your abs thinks you your wheels are locked up.

This should be an abs recall ...especially if the source of the issue is a software error so it isn't anything but a reprogram needed to fix a potontially costly safety problem.

GM never learns.

I can understand some of the explanations given here... air in brake lines, ABS misreading the situation.
But how can the pedal "go to the floor" sometimes but not consistently? if there is air in the lines it does not go away magically. This type of behavior sounds like an intermittent hardware problem in the booster. Like the check valve is leaking wide-open intermittently.
