The Federal Trade Commission (FTC) Cooling-Off Rule allows you to cancel a contract when you purchase something at your home or at a location that is not the permanent place of business for the seller. But not all sales can be canceled under this rule. Exemptions include sales that are under $25, goods or services that are not designed for use in the home, sales made by mail or over the phone, a sale that is arranged from prior discussions at the seller's permanent place of business, goods or services needed for an emergency, and repairs to personal property that are solicited by the buyer. 

The Cooling-Off Rule does not cover transactions that involve real estate, securities or insurance, automobiles sold at a temporary location (as long as the seller has a permanent place of business) and arts and crafts sold at fairs

You might have heard there is a federal cooling-off rule for some purchases. There is such a rule, but it is primarily meant to protect consumers from high-pressure door-to-door sales tactics. It explicitly doesn't apply to automobiles. If you signed the sales contract, you own the car. And the law is on the side of the seller. For new cars, your legal rights can be summed up in the one sentence that's posted on the wall of many dealership sales offices: "There is no cooling-off period."

Mine didn't lose power but it feels like the brakes are stuck and the truck feels heavy. The brake pad life percentage also went down to 15% at only 6500 miles. Even after them having reset it to 100% when I took it in at 3200 miles and 65%. WTF. They drove it and of course , they can't feel anything. I drive this everyday. You don't feel if you drive it around the dealer. Only until you've driven it on a daily basis but it feels like I'm permanently towing something. But anyway, I first took it in at 1100 miles just in case I have to file lemon.

There has been a "recall"/software update for the brake system. Just had mine done this morning, never had a problem before.

Ill list the number once i remember to take a picture of the service record.

Many dealerships do have a return policy. It's usually within 3 business days or 500 miles. You have to read the fine print. If you did that and your dealer didn't offer one, then yes, you're stuck once you drive off the lot.

What does the recall entail?


Sent from my iPhone using Tapatalk

Ok, on my paper work that i received after my visit.

 

"C** N192210460, Eboost control module software false detection with DTC Associated

Cause: complete per factory instructions

Recall customer request perform factory recall

79513 WGI

......."

 

Hope this helps anyone in this situation.  

 

Addition: Right after i received my truck back i had a very hard 2 to 1 downshift, i really thought i got rear ended by a person going 15 mph faster for a quick second.

I do not know if the update had anything to do with it or it was just bad timing.

I never lost my brakes but I lost the power assist which was fixed with a software update. Losing your brakes is a real serious issue in which I haven’t seen reported to date.

This just happened to me as well so I guess they still haven’t fixed the issue. 

 

The warning lights for brake system failure, service ESC, traction control off, and service trailer brake system came on. 

 

Thankfully I was already at the dealership dropping off some paperwork. My sales guy was in the truck with me when it happened as he let me use the dealership car wash.

 

OnStar texted me as well; 

 
Diagnostic Alert: Service the Antilock Braking System in your 2019 Sierra within 7 days. Txt STOP to cancel or visit my.gm.ca/gm/en/l/blah blah blah

 

It’s in with the Tech now.

Not impressed to say the least. I’ve been sitting at the dealership for the past 4 hours and now they say I won’t be getting the truck back today. They’ve reprogrammed it, bled the brakes, bled them again after a test drive and now they say they have to order some parts, a module etc... This is a new build, May 2019ish. These brake issues should have been sorted out by now... Not sure when I’m getting it back...

Well, I did end up getting it back last Friday. They cleared the errors by reprogramming the computer, bled the brakes twice and added new fluid again as stated before but the said they didn’t have to order or install a new module/sensor. When I got it back, it seems to be back to normal. I know they did some testing as they gave it back to me bone dry. Had to find the nearest Costco to fill in back up. Much cheaper for Premium there. ($1.229 vs $1.479 per litre at Shell) For the meantime, it seems to be holding.

Add me to the list - 2019 Sierra AT4 purchased in January at 7500 miles.  Same as most of you - had the power brake failure but still able to stop - I just had to press harder. Reminded me of my '69 Chevy truck.  Cleared out on next restart.  This happened twice before I could get it to the dealer. 

 

From my Dealer sheet:

Cause: DTC C0580. Faulty brake master cylinder, refer to doc 4992039. 2441400 Brake master cylinder replacement - with power brake booster and electronic brake control module.

 

They also did 3 software updates:

Recall - 9104397 N192210560 Engine Calibration Torque Model not accurate

Recall - 9104166 eBoost Control Module Software False Detection with DTC associated - Brake System control module software update

Recall - 9104244 Trailer Integration Module Software Error - (Mar 7, 2019)

 

Just got it back today - I'll keep you posted of any new failures.

We lost our brakes on our new 2019 GMC Denali 1500 - only 3200 km . Just had an update from our dealer  SHAW GMC: Good Morning , just giving you an update on where we are at with your truck. we have had Transport Canada involved as well as 3 GM engineers, we are currently sending and receiving information with the engineers. As things progress i will be keeping you in the loop!

 

So who knows how long this will take?? I’m assuming if Transport Canada is involved then their is a lot of vehicles.

If you lost your brakes how did you stop the truck? Did you hit something? Or did you just lose power assist?

    • Monday looks like a good day for the dealer to test an ac issue. Hopefully it all turns out good.
    • Paid $2.72 for E85 today.
    • Welcome back! No, it definitely doesn't pass the sniff test. Even "ceasefire" needs an alternative definition these days.    $5.29 at Kroger today
    • That makes sense, and I think you are describing the real product problem. Capturing data is the easy part. If the owner or technician has to manually dig through five minutes of millisecond-level logs, the product has already failed. The device would be at the ECM harness, not at the OBD port, so I agree that data retrieval and event marking need to be thought through carefully. The way I am thinking about the architecture is: The recorder itself should not depend on a phone, app, Bluetooth, Wi-Fi, or cloud connection to capture the event. It should always keep a local rolling buffer and lock the event locally. A button, phone app, or small cabin device would only act as an event marker. If the driver feels a stumble and presses the button 10–30 seconds later, the pre-buffer has to already contain the useful data. For data retrieval, the practical options would be a sealed service USB lead, Wi-Fi download, or a phone/cabin companion device. I would not expect the owner to remove the ECM-side module or work with raw files directly. The cloud or AI side would be for interpretation, not for capturing the event. The truck may have no connection when the issue happens, so the evidence has to be saved locally first. After that, cloud processing could help decode the data, compare it against baselines, and generate a readable report. For the first version, I would keep the automatic triggers conservative and objective: driver event marker bus-off error passive voltage drop / brownout device reset FIFO or queue overflow a normally periodic message disappearing side-to-side communication mismatch, if the topology supports that For “learning normal,” I agree with your point, but I would not want to overclaim it as automatic root-cause diagnosis at first. A realistic first step would be learned baseline comparison for that specific vehicle and operating condition. For example, a value would only be compared against similar conditions: RPM range load / MAP throttle position gear / vehicle speed coolant and oil temperature battery voltage AFM/DFM state, if decoded and validated Then the report could flag things like: this periodic message disappeared compared with its normal timing this value deviated from this vehicle’s normal range under similar conditions the same abnormal pattern repeated after the same type of event the anomaly occurred together with voltage, oil-pressure, misfire, or communication changes But I would still call that “abnormal pattern detected,” not “replace this part,” unless there is enough validated repair data behind it. So the intended product would not be “here is a huge log.” It would need to be an event package: what triggered the capture how much pre/post data was preserved what changed before and after the event whether the device itself reset, overflowed, or saw a bus error selected graphs around the event raw data only as supporting evidence From your perspective, what would make this kind of report useful instead of just another datalog? For example: What are the top 5 parameters or events you would want highlighted first? Would you trust a learned baseline for that specific vehicle, or would you prefer fixed thresholds? How much false-positive flagging would be acceptable before you stopped looking at the reports? What would a one-page report need to show for an independent shop to take it seriously? For misfire, AFM/DFM, oil pressure, or U-code complaints, what would you want the tool to flag automatically?
