"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.

When I hear stories like this about the newer trucks, there is no way I'm trading mine in. I have a 2016. I use a key (old school) pre-fob. Because of fear for lifter problems we hear about, I change the oil frequently. And, I have an undercoating that is inspected and renewed annually. Shame that mine has fewer issues than newer models with tech "improvements."

I would question the " no issues with Toyota" for thirty years.
We owned a Toyota Prius for twelve years. Had the same maintenance as any other car. Replaced water pump and timing belt, hybrid battery, and front bearing huds. The head lights HDI were replaced three to four times. The gas engine failed at 292K.
I have purchased five new Chevy trucks over the years and currently driving a 2018. Have not had significant problems with any of them.
I do agree having issues at 5k would not make me happy but it is not the norm I'm my experience with Chevy.

I have the 2019 version of that truck and I have had NOTHING, but problems with the truck. Replaced the wiring harness, went through 3 starters so far, multiple engine lights that come and go. I've owned nothing but chevys, but as soon as this truck dies or costs me much more money, I'll be joint the Toyota club as well. It's sad how the Chevy / GM quality has gone down.

Just wait, lifter arm failure will be next! I had to replace entire engine in 2018 Colorado at 63,000 miles due to that. Chevy would not stand by it, offered me 300.00 towards repair or 2500. Towards trade in! Mechanics at my dealer were awful, had the truck repaired by personal mechanic and leaving Chevy in the dust .. so disappointed.

I've owned GM trucks since 2003 and never had any issues including a truck I gave my granddaughter after putting 272,000 miles on it that still runs like a top.Ironically the supposedly fantastic Toyotas are currently recalling trucks to have the ENTIRE ENGINE REPLACED !! Get so sick of the foreign hype machine trying to denigrate American made vehicles and blowing out of proportion any problems they can find in American made products.

Not a Silverado… but a Colorado Z71 ( 2019) bought new with a couple thousand miles on it, always serviced at the dealer, all maintenance including oil changes. done ahead of recommendations, changed transmission fluid at about 49,000, then at 55,422 miles ( transmission control mod code) 75 days outa warranty by time, not miles, ( dealer replaced valve body in transmission) supposed to be one day job, took nearly 3 weeks, ( $2500 +) on the way home from picking it up, gets check engine lite ( code for coolant temperature sensor) dealer wants another $1300 to replace it. Long story short, traded that thing in for different vehicle , & just took the loss. No more chevys for me

Similar issues. 2023 Silverado Duramax. TCM went bad somehow after OTA update that bricked the truck in my driveway with less than 8K miles on it. Wouldn’t shift out of 4WD or even into reverse. Limped to dealer where they had to fully overwrite updates and replace TCM. Then three tries back to fix rear cam. Chevy uses garbage parts from lowest bidder vendors. Zero quality control. I love how the truck looks but I’ll be lucky to get over 100K miles before serious issues start mounting. Then back to Toyota or Honda.

I dealt with near identical issues a number of years ago with a 2012 Chevy Impala. I lost count of how many times I was at the dealer with that car. At the time, it was a brand new car. I got rid of it in late 2016 but reading this brought back many horrific memories. Like you I was always told that it was a first they had ever seen that kind of a problem which is a load of poppycock. Utilize the lemon law, and take the money and go buy a Toyota Tundra. Not sure why the Big 3 are so much less reliable than foreign vehicles, clearly there are both quality control deficits and quite possibly inferior parts being used.

Bought a 2024 gmc 2500 hd Denali. The problems began at 75 miles. The truck has been in the shop for over 45 days and is currently at the dealer being worked on. So far this is what been replaced. Oil pan gasket, upper oil pan gasket, turbo, galley plug, transmission has been removed, tailgate switch replaced twice, the truck is leaking oil and leaves little puddles everywhere Its parked. I have had 2 new Chevy expresses and 2 new GMC 2500 Denali since 2018, 3 of the 4 have gone to be buy backs. I am finished with GM products. Unfortunately I’m thinking I have to go foreign because I hear ford and dodge are having major problems also.

I have about 76,000 miles on my 5.3l Silverado and my check engine light came on. I had two codes, P0700 and P0711. The P0700 showed a possible cause as a shortened or open circuit within the TCM or a faulty TCM. I drove the truck around town as the dealership couldn’t give me an appointment for a number of days and the check engine light went out. I monitored the transmission temperature as I drove it as the P0711 code said a possible cause was an issue with the transmission fluid temperature sensor. My transmission temperature never went above 165 and I haven’t had any further issues.

That's the problem with America vehicles, they're built for short term. Since the late 80's our manufacturers followed the consumer trend of upgrading. While we used to be proud to own certain brands as they were built to last things began to switch to what was the latest and greatest. Leasing became more and more common, consumers began wanting to upgrade to the next model every year or so. Companies like Ford, GM and whoever owns Chrysler makes most of their money off of parts from second hand+ ownership. You can sell a cheap US car for $18,000 but over the course of 10-20 years it can turn into a $30,000 car after all the repairs and replacement parts. Japanese and Korean companies still take pride in their vehicles, that's why they can still goo 100-200k miles without malfunction.

I purchased a used 2017 silverado 1500 from a Bentonville, MN dealership. After 6 months the truck failed to start. As a result of this reoccurring issue I have replaced the battery, ac sensor, and starter. I am still experiencing intermittent crank no start issues, messages on the information center to lower the drivers window and raise it up, drivers door won't open even though it is unlocked. Check engine light. The check engine light was resolved, but the other issues remain.

I had a new 1980 c10 straight six 3 on the tree and only power steering. I sold it 12 years later for what I paid for it. Chevy and Ford street cred was well earned, back then. I bought a new 1985 Silverado, the right front fender hung down lower than the hood, dealer said “you REALLY don’t want me to fix it, do you?” Implied threat understood. The overdrive tranny give out, my repair bill, I asked how to keep it from happening again. Dealer said “keep it in 3rd gear, no 4th overdrive”. Then the nightmare V8-6-4 was invented. Dumbed down to V8-4, I said no thanks in the Silverado; but I really wanted the z06 with same stupid valve train AND a shuddering tranny. And RANGE fixed all that. For my truck I swapped s for t, Silverado for Tundra. Happily ever after I hope, as I got the last V8 Tundra and b’lieve it will go a million trouble-free miles, fingers crossed. If not forever, I still won’t buy a new mouse-sized motor-in-a-gigantor truck; no matter how many light-bulb-lifespan turbos and everready batteries they stuff into it, be it Toyota, Chevy or Ford.

We own a 2024 chevy silverado 1500, with 10,000 miles on it. It was in the dealership for a month for a valve box controller in another word the transmission, we where told these trucks parts where built during covid, and all parts are on back order for up to 1 yr, with all the fighting I did we received the part in a month, chevy knew about this but still put them out to be sold, we are not sure if we are keeping the truck we just don't trust it.

So, if a serpentine belt is not covered by warranty and you had to pay for that... Then later it turns out that the belt failed due to a COVERED part was the cause, will they refund you the money you paid them for the serpentine belt replacement? It seems fair that they should considering a false diagnosis caused you to have to pay for something that did not resolve your issue.

Check your alternator, I had a dodge with alternator going bad. Bearing sticking. It caused voltage spikes and computer was throwing random codes all over. Replaced the alternator and all the problems disappeared. Having your serpentine belt jerking would give the same behavior, if one of your idlers was sticking.
The voltage spikes also kill your battery.
