Looking for some advice from fellow Super Duty owners on both a possible brake failure and how you’d handle the dealership situation.
The Breakdown
Tuesday evening, I was traveling on I-40 through Sallisaw, Oklahoma, at approximately 80 mph when, without touching the brakes, I suddenly felt a wobble/pulsation from the driver’s front wheel that transferred into the steering wheel. Almost immediately, multiple warning lights illuminated, and I knew something was seriously wrong.
I slowed down and pulled onto the shoulder. When I got out, I initially thought the truck was on fire because of the black cloud coming from the driver’s front wheel well. Fortunately, what I was seeing appeared to be brake dust rather than smoke from a fire.
Under the hood, nothing looked obviously wrong, but the instrument cluster displayed warnings for:
● ABS
● AdvanceTrac
● Hill Descent Control
● Collision Avoidance
I managed to limp approximately 1/4 mile to the nearest exit at 3–4 mph. The brakes seemed to be grabbing intermittently, accompanied by a grinding-type noise that seemed to diminish when turning.
For context, this is my 2021 F-250 Platinum 6.7L. Approximately 16,000 miles ago, I upgraded to EBC HD brake calipers and Bendix HD rotors when the original pads needed replacing. I’ve had absolutely no brake issues since that upgrade.
Question #1: What do you think happened?
Could this be a caliper suddenly seizing, an ABS module malfunction, a wheel-speed sensor issue, or something else? What concerns me most is that this happened at highway speed without any brake application. I’m particularly interested in whether an electronic system could have commanded the brakes to engage unexpectedly.
The Dealership Situation
By this point, it was after 8 p.m., and finding a repair shop wasn’t an option. I hired a wrecker and had the truck towed approximately two miles to Harry Robinson Ford in Sallisaw. Since I normally have my Ford dealership handle my service work, I figured another Ford dealer was the safest choice.
Unfortunately, my job required me to be 2.5 hours away the following morning, so my daughter made a five-hour round trip to pick me up.
I left the dealership a detailed three-page description of what happened, service records, extended warranty information, and the keys in their night drop box.
Here’s how things have gone:
Wednesday, 8:30 a.m. – Called shortly after opening. The service representative told me they’d already pulled the truck into the shop and would call once they had a diagnosis.
Wednesday, approximately 12:30 p.m. – Having heard nothing, I called for an update. The same person said they’d just started looking at it about 20 minutes earlier and would contact me when they knew more.
Wednesday, 5 p.m. – Still no communication, so I asked to speak with the service manager. He explained that they were backed up 3–4 weeks on diesel work but were making an exception to prioritize my truck since I was a stranded traveler. He had no diagnostic information and told me not to call again until I heard from them.
I understand dealerships are busy, and my truck arrived unexpectedly without an appointment. I certainly don’t expect them to put every other customer aside for me. However, after being told twice that the truck was being examined, I thought it was reasonable to expect at least some preliminary information by the end of the day.
His response left me feeling like I was being unreasonable simply for asking.
I decided to give them some space and went the next 24 hours without calling. Unfortunately, I still received no update now with it at the dealer 48 hours. FordPass shows it has moved to their lot, but no warnings have cleared & no service ticket has been started.
Where Things Stand
Today, I called the service manager at my home Ford dealership for advice. I have a trip coming up in approximately a week and really need my truck back.
He suggested calling the Sallisaw service manager, politely establishing a firm deadline for a diagnosis, and explaining that if they cannot evaluate the truck by then, I’ll need to arrange transportation to another shop. He noted the service system had no new record of a new ticket being started, but said that may not update until the ticket closes.
My home dealer also contacted an acquaintance at another Ford dealership within reasonable towing distance, but that dealer said it would be approximately two weeks before they could look at it.
That leaves me in a difficult position. I don’t want to alienate the dealership that currently has my truck, especially if they are genuinely trying to work me into their schedule. On the other hand, I can’t afford to have it sit indefinitely without even knowing what’s wrong.
Moving it to another shop means another tow bill and potentially starting the entire process over again.
Question #2: How Would You Handle This?
Would you:
1. Give the current dealership another day or two (48hrs in) before escalating?
2. Call the service manager and respectfully request a specific diagnosis deadline?
3. Cut your losses and tow it to an independent diesel/brake shop?
4. Consider another Ford dealership, even if it means paying for a longer tow? Quote to Tulsa was $700
5. Ask my local service department to call the dealership on my behalf to say a few kind words & gauge the situation (they offered)?
And, specifically, what would you say to the service manager to get some movement without damaging the relationship?
I’d really appreciate hearing from anyone who has experienced a similar brake/AdvanceTrac failure or has dealt with being stranded at an unfamiliar Ford dealership.
Thanks in advance for any insight.
