Woman Buys Extended Warranty For Used GMC. Then She Tries To Use It: 'Headed Back To The Dealership For The THIRD Time'

A Northern Michigan owner of a 2015 GMC Yukon says she is on her third trip back to the same dealership for the same driver's side window problem, after paying for an extended warranty precisely to avoid this issue.

Average Al's four-minute TikTok details how a window regulator repair reportedly came back with the door trim broken, the interior covered in fingerprints, and the switch module reassembled incorrectly. According to her, a follow-up appointment was booked to fix the original symptom, but the car returned with all four switch buttons loose. She names the dealership openly in the replies.

The caption tags the dealer and the problem: "Tell me why I'm headed back to the dealership for the THIRD time… for the SAME window module issue."

The Repair That Wouldn't Stay Fixed

Average Al opens with a disclaimer. "I don't mean to sound insane. Please don't call me crazy. I'm normally not a Karen, but I feel like I'm being treated like a Karen about this situation," she says. She says she bought the Yukon with an extended warranty that covers electronics, including the windows. When the driver's side window quit, she took it to her local GMC dealer.

According to Average Al, the Yukon came back damaged.

"They had broke a piece of my trim off and there was fingerprints all over on the inside of the window," she says. The four-button switch quadrant on the driver's side was not reassembled correctly: "Like the buttons weren't working, like they were stuck, like they didn't assemble it correctly."

The second visit was supposed to address that. She dropped the Yukon off on a Monday for a Tuesday appointment. By Tuesday afternoon, she says, the dealer had not called, was not picking up the phone, and her husband's texts had gone unanswered.

She says that when she walked into the service department in person, she learned the car had not yet been looked at. The vehicle eventually came back with the trim repaired and the technician's plastic debris cleaned out of the door, but with the switch buttons loose.

"The switch module, like all four of them, is loose. So now I'm thinking like a clip or something's broken," she says. The express up-and-down function on the windows, which she had reported twice, was reportedly still not working.

In replies, Average Al identifies the dealership as Serra Buick GMC of Traverse City, Michigan. The dealer is part of Serra Automotive Group, a Fenton, Michigan-based, family-run network that operates 63 dealerships across eight states, including two dozen Michigan locations stretching from Traverse City to Saginaw.

She references the Fenton acquisition directly in the video: "I do believe it used to be a family-owned GMC dealership and a giant family from Fenton purchased."

Is The Extended Warranty Worth It?

Average Al's experience raises broader questions about extended warranties. Consumer Reports' recommendation is that they generally aren't worth it: "Past CR member surveys showed that car owners typically paid more for the coverage than they got back in direct benefits." The magazine advises buying a reliable model and skipping the contract.

The Federal Trade Commission's consumer guidance on extended warranties goes further, warning buyers that an auto service contract is not a warranty as defined by federal law and that "there may be so many limits and conditions on which repairs are covered that the service contract is worthless."

But Average Al is not wondering whether or not the contract is worth it. Rather, she says the contract is paying for parts, and she is paying labor, and the work itself is the problem. "I'm just trying to figure out what the [expletive] is actually going on there," she says.

A Known Trouble Area On The Yukon

The window system on her car has been a documented complaint pattern for owners of 2015 Yukons. CarComplaints.com logs 79 National Highway Traffic Safety Administration complaints for electrical system problems on the model year at an average reported mileage of 134,000 miles.

The switch on a 2015 Yukon does not drive the window motor directly; it sends a signal through the body control module (BCM), which then commands the motor. That architecture means a fault can sit in the switch, the regulator, the motor, the wiring, or the BCM, and a repair that addresses one component without testing the rest is exactly the kind that comes back.

"Every Dealer Operates This Way Now”

The comment section was mostly supportive, with viewers saying that the problem is the work, not the customer.

"Every dealer operates this way now," ShawnTech wrote. "Manufacturer does not care because the dealers are privately owned."

A separate thread pointed Average Al to the option of taking her warranty to a different dealership.  "Purchased warranties are not typically dealer specific," cjc491 wrote. She replied that Serra is the only GMC dealer in her market.

Tina Marie added, "It sounds like because they are the only GMC certified dealer in the area that they know they can just do as they please."
