"In my 30 years of owning Toyotas with no issues, I took a chance with Chevrolet, and it begins."
Imagine owning Toyota vehicles for 30 years, and you buy your first Chevrolet vehicle. It's a 2024 Chevrolet Silverado 1500 2.7-liter TurboMax. You like the look and capabilities of the new Silverado, so you pull the trigger and get it.
However, when the odometer hits 5,000 miles, the problems with the new pickup begin. That's what Phil Layton says in a Facebook post on the 2019 - 2025 Chevy Silverado and GMC Sierra Owners Facebook page.
Phil's troubles begin at an unexpected 5,000 miles mark.
Phil says he's already had the truck, which only has 5,000 miles, at the dealer to replace the serpentine belt, and then shortly after, they also had to replace the tensioner pulley.
Then, he gets the truck home, and now the truck's check engine light comes on, and it looks like there are other problems with his brand new Silverado 1500. Here is Phil's unfortunate story.
Phil's frustration is understandable as he shares, "I was never a hater and even a skeptic about everyone that said they had issues with their Chevrolet Silverado 2.7-liter, but my day (week) finally came."
"I have a 2024 2.7 with only 5,145 miles on it. A constant chirping sound has come from the serpentine belt for the last month."
"I took it to the dealer, and they tell me "the belt is completely glazed" (with 5,000 miles on the clock), and they replace the belt."
Phil's disbelief is evident as he recounts, "I told them the truck has 5000 miles on it, and the serpentine belt should last between 75,000 and 100,000 miles. He said, 'I agree. I've been doing this job for 17 years, and I have to tell you this is a first for me; I have never seen this before, and I have never heard this happening before.'"
"In any event, he said it's ready for pick up. Before I got off the phone, I said, This is covered under warranty, correct? There's only 5000 miles on the vehicle and it's a 2024."
You can hear Phil's frustration as he recounts the dealer's response.
"He said that serpentine belts are not covered under the GM warranty as they are considered "wear and tear" items. Obviously, I came unglued on the phone and told him that if I had 50,000 or 60,000 miles on the truck and this happened, that makes sense, but 5,000 miles and you're telling me that it's not covered?"
He Had the Truck Back for A Day, and There Are More Problems
"So, the next day, the chirping sound comes back. I took it back to the dealer, and they tell me the tensioner pulley needs to be replaced, and a bearing is seizing up, and they're replacing that as well."
Next, It's the Check Engine Light
He continues, "Then, this morning, I'm heading to the gym at 5:30 am, and when I use both turn signals, they would say "check L signal" and "check R signal," but there are no codes."
Phil is connected to the myChevrolet mobile app to check the truck's Vehicle Status report on his phone.
"Then, about two hours ago, my check engine light came on on the way home from work. There is an error code, P00FF, on the Body Control Module (BCM)."
"So, I disconnected the negative battery cable to "reset" the battery, but there was no fix. My check engine light is still on. I tried a few other troubleshooting techniques, but no go. The check engine light is still on."
Phil Does Some Research
"I tried to do some research on the BCM for the 2024 2.7, and from the few posts I've seen from others, the majority seemed to go the lemon law route since it's a pain to actually narrow down and fix the "electrical issues."
"In any event, in 30 years of owning Toyotas with no issues, I took a chance with Chevrolet, and after only 5,000 miles, the problems begin."
"I'll give Chevrolet the opportunity to fix the issue, but from what I'm hearing and reading, it doesn't look promising."
It's Back to the Dealer
After returning his new truck to the Chevrolet dealer, he gets back this report from the technician who worked on his pickup.
After performing a systems testing and inspection, I found the chirping noise originates from the A/C compressor and goes away when the clutch is engaged. Repair requires A/C compressor replacement.
The check engine light is on—found code B2HA3. I performed system testing and inspection and found the park position switch sticking, causing short-to-ground on circuit 553 and the code to set. The repair requires a transmission control replacement.
After Reading This Report
Phil says,
"Has anyone heard of the Transmission Control Module (TCM) "failing" on these trucks? I can't find a single case where the TCM failed on the 2.7 Silverados."
"I'm thinking this is gonna be an electrical issue that's ultimately not gonna be able to be resolved, and it'll be a Lemon Law buyback for me; but, curious if anyone has ever heard or seen of a TCM failure on these trucks before?"
A user on Reddit says,
"I picked up my new 2024 Silverado LT on Wednesday of last week. Friday, I was leaving my driveway and got this message, and the vehicle went into limp mode. The truck has 248 km on it. The dealer brought it in today and says the TCM is faulty and needs replacing."
What is the Chevrolet Silverado TCM?
The TCM (Transmission Control Module) is a computer that controls the automatic transmission's operation, including gear shifting and hydraulic pressure, ensuring smooth and efficient transitions.
Should Phil Pursue the Lemon Law?
Phil lives in Florida, and the Lemon Law covers "Defects or conditions that substantially impair the use, value or safety of a new vehicle (these are called "nonconformities"). These defects must be first reported to the manufacturer or its authorized service agent (usually, this is the dealer) during the "Lemon Law Rights Period," which is the first 24 months after the date of delivery of the motor vehicle to the consumer."
"If the manufacturer fails to conform the vehicle to the warranty after a "reasonable number of attempts" to repair these defects, the law requires the manufacturer to buy back the defective vehicle and give the consumer a purchase price refund or a replacement vehicle."
Phil Has to Give Chevrolet Time To Fix His Silverado
Under Florida's Lemon Law, a "reasonable number of attempts" to repair a vehicle generally means three repair attempts for the same defect or 30 days of cumulative time out of service for repairs before a vehicle is presumed to be a lemon.
Conclusion:
It's important to note that if Phil's Silverado has been back to the Chevrolet dealer for repair of the same recurring problem at least three times, he or his attorney must give written notification by certified, registered, or express mail to General Motors (not the dealer) to afford a final opportunity to repair the vehicle.
If the Chevrolet dealer cannot fix his 2024 Chevrolet Silverado 1500 2.7-liter TurboMax, he could be in for a long, uncomfortable ride.
