2024 Chevrolet Silverado 1500

On [XXX], I [XXX] ) experienced the following issues with my new 2024, Chevrolet Silverado - 1500: • Front Windshield Wiper Washer Fluid not spraying/dispensing. • No messages or symbols displayed on the Driver Information Center dashboard indicating Windshield Wiper Washer Fluid Reservoir low/empty. • Inspected the reservoir that holds the fluid and did not observe low/empty. • Took it to the GM dealer 4 times and they were unable to repair. My vehicle has a recurring defect with the windshield washer system where the washer fluid does not dispense when activated. This issue occurred on a new vehicle and has persisted despite service attempts. When the washer fluid fails to spray, I am unable to clear dirt, dust, road debris, or moisture from the windshield while driving. This significantly reduces forward visibility, especially at freeway speeds or in conditions where debris from other vehicles hits the windshield. The inability to clear the windshield immediately creates a safety hazard because it can obstruct the driver’s line of sight and increase the risk of a collision. This issue is not cosmetic, it directly affects safe operation of the vehicle and the driver’s ability to maintain visibility during normal driving conditions. I am reporting this because the defect is ongoing and may affect other vehicles of the same model. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Regarding Recall Repair on My Truck To Whom It May Concern, I am writing to formally express my frustration and concern regarding the recent service performed on my truck, which I purchased pre-owned from Tropical Chevrolet with only 4,700 miles. 9 months after my purchase, the vehicle received a manufacturer recall involving the motor, requiring a full engine replacement. I brought the truck to Bomnin Chevrolet West Kendall for the recall repair, expecting that it would be handled correctly and at no cost to me, especially since the truck was running perfectly before the recall work. After the motor was replaced, I was informed that the Air intake manifold currently on the truck is “not original.” This Air intake manifold was already installed when I bought the truck from Tropical Chevrolet, and I was never informed of any aftermarket or non-original parts at the time of purchase. Now, after Bomnin Chevrolet completed the recall repair, the truck has a check-engine light, and I am being told I must pay approximately $900 to change it for original air intake manifold to remove the check engine warning light. I think the mecanic took out the program.from the computer and Now they want me to pay.This is unacceptable for the following reasons: 1. The truck had no check engine warning lights and was running properly before the recall repair. 2. The Air intake manifold was already on the truck when I purchased it from Tropical Chevrolet. 3. I never approved or installed any non-original parts. 4. Bomnin Chevrolet removed and reinstalled the parts during the recall repair. 5. I should not be held financially responsible for problems created during the recall repair process. I am requesting that this matter be reviewed and resolved immediately by Bomnin Chevrolet West Kendall. The truck should be returned to me in the same conditions I gave it to them and the recall fix.Thank You Regards, Rafael Lafee

The radio cuts out which then kicks my cell phone off/navigations kicks off every few minutes. On one occasion the speedometer stopped. This cutting out makes it unsafe to drive because you are messing with the radio trying set up phone again or trying to get the navigation going again etc instead of paying attention to the road. over the past 1 plus years i have vearved off the road. i have had my truck in for repairs 7 times in 3 different dealerships. they have replaced the radio twice (found out later the 2nd time was a lie), a coaxial cables , and amplifier. i am told the same problem is happening on numbers GM vehicles and GM does not have a fix. I have requested my money back 3 times due to the safety of driving as is.. Gm have given me the run around all through it. they are aware of the problem but do not know how to fix. My third request did get addressed but was denied because they said the lemon law is only good for one year. I am about to run out of warranty and Gm has never fixed the problem. I am not the only one there are alot of this vechiles with this safety issue. i need someone to help protect myself and my family. GM needs to be forced to refund everyone money since they cannot repair these vehicles to make them safe.

For the first time I purchased a brand new vehicle off a dealership lot…What a mistake. While the dealership itself was an awful experience I thought it was worth it for a Chevy Silverado. After all my previous one was so reliable. WRONG. The first issue I found was I was unable to shift into reverse to back out of the driveway of a fire station I volunteer at. After driving forward a couple times and shutting the vehicle off and shifting multiple times I had to be towed out in reverse. I was able to drive home but the transmissions slipped once and the vehicle slowed abruptly. The check engine light was now on. I dropped the vehicle off at the dealership over the weekend and on Monday they called and informed me the 2024 Silverado misfired once and nothing was wrong with the transmission. There was nothing they could do. About two months later I was driving to work as a career firefighter/paramedic when my vehicles check engine light came on and a message informed me that I was in “reduced acceleration mode”. I slowly and carefully made my way to work and brought the truck to the dealership after my shift. The check engine light was now on again. They informed me later that day that I had a faulty valve body in my transmission. They “unfortunately” could not give me a completion date on my repair as they had no ETA for the replacement part. It appears the part is in high demand. This makes sense as a quick google search shows this is a widely known issue with the 10 speed transmission. So far I have been unable to get a rental vehicle between the dealership and GM. Aside from my house my 2024 Silverado is the largest purchase of my life. And at 15,000 miles I am without it for the foreseeable future. As a first responder the communities I serve depend on me to respond from home at any hour. My family and I are living in a DIY renovation while also starting a farm business. I need a dependable vehicle and regret spending $53,000 on a new vehicle. I have more to say.

Hairline crack developed on the transmission cooling line at the connection of the thermal bypass block. After looking up it seems to be common. Yes, there have been user-reported issues with transmission cooler lines leaking or cracking on 2024 Chevrolet Silverado models equipped with the 3.0L Duramax diesel engine, including at or near the thermal bypass block connection. These reports primarily come from owner forums and appear to affect a subset of vehicles, often discovered during routine maintenance or after noticing fluid spots under the truck. Symptoms can include hard shifting, fluid seepage on the undercarriage, or low transmission fluid levels, with some cases progressing to require towing if not addressed early. For instance, multiple owners of 2024 Silverado 1500 models (including ZR2 trims with the LZ0 3.0L Duramax) have described leaks originating from the cooling line block or thermal bypass area next to the oil filter, sometimes involving hairline cracks in the lines themselves.  In one detailed account, a 2024 model with around 35,000 miles experienced fluid leaking from the cooling line block, leading to replacement of seals and the entire line assembly due to cracking discovered after initial repairs.  Similar problems have been noted on closely related 2023 models, where leaks at the thermal bypass valve necessitated replacing the valve, O-rings, and all cooler lines, with some users reporting hairline cracks as the root cause.  Parts like the lines have been on backorder in some cases, causing repair delays, and resolutions are typically covered under warranty (e.g., powertrain coverage up to 100,000 miles), though repeated visits to dealerships are common. These issues seem tied to the 10L80 10-speed transmission paired with the 3.0L Duramax, where the thermal bypass valve can contribute to overheating or fluid flow problems if faulty, potentially exacerbating line wear

The coolant control valve and the transmission control module are having to be replaced on thousands of Silverado 1500s from 2022 to 2025. Both parts have been updated, but there is no recall and many people are being left stranded due to this. Mine has not currently failed, but I am older and really don’t want to get stranded due to a known issue. Why wouldn’t they have been forced to do a recall General Motors should be replacing these as a preemptive precaution.

Complaint Description On Tuesday October 28th, 2025 while driving to work, my 2024 Chevy Silverado LTZ suddenly went into limp mode during normal driving. The truck would not go into reverse at all. I had to use OnStar to call a tow from my residence because the vehicle was not safe or able to be operated. The truck has been at the Chevrolet dealership since that day and as of today (November 7th) it still has not been repaired. The service department confirmed it is a failed transmission valve body. Research shows this is a recurring and known issue on many GM trucks and GM does not appear to have a permanent fix yet. Component/System that failed: Transmission Valve Body failure. Component is currently located at the GM dealership and is available for inspection. Safety Risk: This failure caused sudden limp mode, loss of power, and inability to reverse while in active traffic. This put my safety and potentially other drivers at risk due to sudden unexpected deceleration and inability to maneuver safely. Problem Confirmed: Yes. Confirmed by GM dealership service technicians. Inspection: The vehicle is currently at the GM dealership. No manufacturer field rep, insurance, or police inspection has occurred yet. Warnings / Codes Present: The failure occurred without prior early signs that morning. When it failed, OnStar diagnostics reported: P2732: Transmission System — “Engine and Transmission System not performing as expected.” P0700: Transmission Control Module requested Malfunction Indicator Lamp illumination. Emissions related DTC set in the Transmission Control Module. Both codes triggered at the time limp mode activated. Best Assessment: This appears to be an ongoing recurring GM transmission valve body issue affecting newer GM trucks. The failure caused a sudden loss of drive capability and is a safety hazard that requires NHTSA investigation.
