general problems of the 2018 Chevrolet Silverado 1500 - part 2

Purchased this vehicle from a used car dealership 2 months ago. Now the transmission seems to be going out with 132,000 miles on it and funny noise from the transfer case. I have researched and found numerous complaints about the drive train on this vehicle and as a disabled veteran I don't have the funds to have it fixed. How can I get a recall in place for this issue?.

10 miles from home on [xxx] after thanksgiving with my children sleeping at [xxx] in snowy cold weather, my engine began to fail. Power was limited on hills and the check engine light would come on and go back off when on flat or downhill. The next morning I took my truck to the dealer that I purchased it from where I was told the lifters had failed and I need a new engine. 1000 miles after I replaced my engine my transmission failed completely requiring a transmission replacement. Immediately upon picking up the vehicle and going down a long hill in the area, engine breaking turned on as expected but as the truck tried to slow itself, after 2 or 3 downshifts, the transmission began making a loud grinding sound and while still going close to 50 mph, the speedometer showed 10-15 mph and the tach dropped to idle. The transmission was decoupled from the motor. When gas was reapplied it seemed to make the connection again and resume normal driving. I called the dealership whose techs did not believe me and told me that I could 'turn off' the engine breaking feature. The situation continued to worsen each drive and it would do it more often. This was unacceptable and they finally had a tech ride with me to experience it and immediately agreed there was an issue and reordered another transmission. The third transmission did not fix the issue and was experienced immediately. They are now guessing how to fix the issue telling me I have to replace the transfer case out of my pocket with no diagnosis, not sure what is causing it and have not fixed the problem. Videos would not fit in upload due to size. Videos show speedometer failure. [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The contact owns a 2018 Chevrolet Silverado 1500. The contact stated while driving at an undisclosed speed, the vehicle stalled and lost motive power. The vehicle was taken to the dealer where it was diagnosed with engine failure. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The contact stated that the engine and transmission were recently replaced, and the vehicle was released by the dealer and the failure occurred three days later. Additionally, the contact stated that the dealer installed a rebuilt transmission and engine, with a warranty up to 100,000 miles. The manufacturer was made aware of the failure and a case was filed. The contact stated that the repair was declined coverage under warranty. The failure mileage was approximately 41,000.

My truck has had transmission issues since we purchased it. At 79,000 miles the factory transmission finally went out and needed replaced. The truck currently has 81,000 miles on it and is already having transmission problems with the rebuilt parts. Background: the truck began having hard downshifts since purchase. Over the course of our ownership, we noticed it started struggling with shifting from 2nd gear to 3rd and 3rd gear to 4th. Constant "clunking" and shuttering when trying to shift. Approximately November of 2024 the truck suffered from the known gm transmission failures. It was almost "skipping" upon acceleration and had a very hard time with cycling between gears. The transmission began making a sound comparable to a normal operating diesel truck (almost sounded like the turbo engines upon acceleration). The truck was sent to the dealership and the transmission was replaced. However, since this replacement we are now experiencing similar symptoms to the previous transmission. There is a very hard downshift, there is clunking sound when the truck is trying to go from 3rd to 4th, and the truck has a noticeable gear burning smell when driven long distances.

Transmission vibrates when it approaches 35 mph and 65 mph. The vibration feels like rumble strips and last for 3 seconds.

The truck started shuttering one day it was like I was driving on the drunk bumps but I wasn't. Also it will drop gears when it shouldn't and at times it will kinda jump like it's losing power and don't want to go. I have taken it to my step dad who has been a transmission mechanic all his life and he said the transmission needs to be rebuilt but even rebuilding it won't solve the problem because it is a flaw in the way it was made so rebuilding it they use the same parts and everything so it will eventually do the same thing again it's all just a matter of when. He also had me go to another really good transmission guy and he said that we could replace the torch converter but still may need a rebuild l. I don't know if any that has to do with my passenger tire wear or my wheel bearing coming loose while driving only one bolt was holding it on when my husband checked it. The wheel bearing coming loose is pretty big safety problem. As for the transmission my step dad works at a transmission shop and he said they get probably 3 to 5 trucks a week having the same problem mine is having and I know they have been recalls on other trucks that have the same problem as mine just my one wasn't in the batch they recalled .

No check engine light come on until continued driving over 15-20 miles. Transmission slams into second gear when taking off or when stopping it may or may not downshift into first causing safety issues when in traffic. Possible electrical error or clutch inside transmission. On this model it is a sealed transmission so no way of identifying if metal shavings come out with a transmission flush. The issue only happens when vehicle is at temperature, if under and still cool drives perfect but as soon as it hits the temperature of 210 it slams very ugly.

Transmission jerking on downshift between 3/2 and 2/1 gears! I have seen gm has been aware of a recent transmissions issue with 2012-2018 plus 2019-2022 years.

The transmission has been slipping since the truck was brand new (<100 miles) and has always slipped but recently became worse and slips all of the time. This is a known issue with this transmission and should be included in the recall. The transmission slipped going around a curve and almost lost control of the vehicle.

6l80 transmission out of no where started kicking in and out of gear while in busy traffic. The motor would rev up and then kick itself back into gear multiple times. This wasn’t stop and go traffic also moments later I was at a light turning left as I did the vehicle start this losing power to the transmission except this time I was in the oncoming traffic’s lane trying to turn. Thankfully the other vehicles stopped although it could have ended much worse.

Bad torque converter cause transmission to totally fail. Had chevy do transmission flush,2 yrs ago. Back in Aug 2024, transmission started to slip,while driving,then totally failed,no forward or reverse gears,nothing, had truck towed into chevy dealer, almost $7000. 00 later,transmission had to be replaced.

Transmission failed and truck shut down mid road while going uphill. Shifting jumps when gears are switched and power jumps and goes down while stepping on gas pedal. At first it showed a check engine light but because I was traveling I had to skip and tried turning on again. It happened at least 5 times while on the road that day and now shifting is messed up and jumps while stepping on gas. I inspected and took to a mechanic for an inspection and said need a new transmission unless there is a recall because it happens to many 2018 chevy silverados 1500.

Transmission failed at approximately 120,000 miles. All maintenance had been done and 90% of miles on vehicle were highway miles. Appears as though there's a thermostat mounted on the exterior of the transmission that is prone to failing around the 100,000 mile area, and when this part fails, there is no transmission fluid circulating to be cooled, so the transmission gets so hot it fails. There are tons of youtube videos from many gm owners that have had to spend thousands and thousands of dollars to replace the entire transmission, when general motors knows of the faulty part.

2 separate lifter failure incidents at 61,000 miles. One failure, happened on a busy interstate, while flowing with the speed of traffic. Truck started to misfire, jerk and blow smoke. I had trouble getting to shoulder of highway to get out of the speed of traffic. The issue was a collapsed afm lifter # 6. All the lifters were replaced on the passenger side on my dime. 450 miles later, I had to limp again to the repair shop that performed the previous repair to find afm lifter # 4 failed this time. Gm has been knowing about these lifter issues for many of years and this is a safety concern while on busy highways.

I've been in and out of dealers over the transmission shifting points and hard down shifts when almost stopped. And the a/c condenser has cracked on the side for no known reason at 75k miles except for the fact of bad manufacturing.

I’ve had to have the transmission replaced before hitting 123k miles there is a constant shake, tremble in the car that dealer mechanics cannot figure out and they relate the issue to the transmission electrical dashboard and ac lightning fixture burnt out.

The contact owns a 2018 Chevrolet silverado. The contact stated that the vehicle had experienced several safety related failures which included unintended acceleration. The contact indicated that the transmission to be replaced on multiple occasions due to the failure. The brake system had malfunctioned and caused the brake pedal to become hard to press. The brake master cylinder was replaced and the failure was remedied. Also while driving the power steering had failed causing the steering wheel to become difficult to turn in either direction.

The vehicle's motor mount was replaced and the failure was remedied. The manufacturer was not yet notified of the failures. The failure mileage was 52,000.

Vehicle shuts off while driving in traffic at low and high speeds stabilitrak service light comes on and the vehicle dash goes dark radio and temp control panel go dark/ black.

2018 Chevrolet silverado 2020 was under warranty (22,000 miles)…. Felt a little vibration in my steering wheel and suspected a transmission problem and called the dealer’s service department. I told them what I felt and they said…yes you have a transmission problem (that Chevrolet knows about) bring it in and we will fix it. The fix was…change transmission fluid to synthetic. Now I was not comfortable with the repair but what can I do. I also know changing to the synthetic fluid can handle higher temperatures and will not breakdown as quickly. So my point is Chevrolet knows and knew about the problem and did not even think about a recall due to the expense it would cost them. Chevrolet expects me to absorb the cost of a manufacture problem. Last year was the start of my families transmission problems. It started may of 2023 with my 2014 silverado’s transmission (175,000 miles) and ended up getting it overhauled. The truck was not abused. November my 1st grandson’s 2018 silverado’s transmission failed, December 2nd grandson’s 2015 serria’s transmission failed. I also recently (3 days ago) found out my friend’s 2018 silverado went failed last year. All within a 6 month’s period. Now I have lost my 2018 silverado transmission (mentioned above) with 88,000 miles. This is just my family…I really can’t imagine what is going on country wide. All of the above events has prompted me to look into this problem. Every transmission shop and dealer is telling me Chevrolet knows and knew about the problem…I can go on. I am very concerned and will not stop at getting resolve with gm/Chevrolet taking ownership of the transmission problem. Sure I want help. . . But I also want to help others with the same problem.

Doing 65mph on interstate on cruise control, the transmission went into 'false neutral' and engine revs went sky high. Truck slowed quickly, almost got rear ended. After that, the transmission did engage and I barely made it home. Very dangerous! transmisison had to be rebuilt. Only 126,000 miles on a 2018 truck.

Vehicle wouldn't accelerate while in moving traffic. Rpm gauge would move but speed gauge would not and vehicle would not accelerate past 30-35. When I pulled over and put my vehicle in park then attempted to put in drive, it would not move. Transmission light turned on. Had it towed to a mechanic who after diagnostics, states it's definitely the transmission/torque converter.

Transmission issue!! jerks on downshift as well rpm ramp up after shift of gear in 2nd to 1st gears.

My truck has been into the dealership repeatedly from Aug 2024 to where it sits now to this day because of the engine and the electronic fuel management system. This fuel management system has destroyed my engine by allowing excessive oil consumption to which it turns the oil black. The engine goes from v8 to 4 cylinder to save on fuel which makes the engine work harder. It causes the rocker arms and pistons to work harder which makes them fail. These problems have occurred with my truck and now the dealership wants 20,000 to replace the engine when they worked on it continuously even after my warranty period had expired. Keep in mind that they were still fixing these problems when my warranty hadn't expired yet they fail to fix it properly. I make payments on a truck that I hardly ever get to drive. I have service invoices to back up my claims. There are numerous others that are dealing with this problem and it's all over the internet so I am not the only person.

The contact owns a 2018 Chevrolet Silverado 1500. The contact stated that while driving at unknown speeds for an extended period of time, the transmission temperature, the traction control, and the check engine warning lights illuminated. The contact was able to continue driving. The contact stated that when the failure occurred on some occasions, he would come to a stop to allow the vehicle to cool off. The contact stated that on other occasions, the vehicle would begin to jerk upon releasing the accelerator pedal quickly. The contact also stated that it was difficult to shift into gears when the failure occurred. The contact took the vehicle to an independent mechanic, where it was diagnosed with an unknown failure. The contact stated that the transmission was replaced. The manufacturer was not notified. The failure mileage was approximately 130,000.

Unknow getting gas in oil at 62532 miles on it which can cause the motor to grenade. A lot of the 5. 3l on 2018 has this trouble from watching utube and using research, should be recalled and transmissions trouble as well.

Torque converter failed resulting in failure of transmission. Requiring complete replacement of transmission at the cost of $7100 from dealership.

Transmission is having hard shift and shutter at a speed of 60/65.

The gm 6l80 transmissions have a faulty torque converter. When it goes out it causes a horrible vibration and drive train failure. Which leaves you stranded in traffic or on the side of a busy highway. These transmissions have been installed by gm since 2013 knowing they fail prematurely as early as 60k miles. It’s a running joke that this transmission saved repair shops because of the sheer amount of failures. With the cost passed on to consumers. There are several in detail breakdowns of the defect in this part on various social media platforms and internet forums. You can call any transmission shop across the nation they can confirm the defect. There where no warning lights prior to, during, or after the failure.

The truck excellerate when I stop at stop sign or red light, with my foot on brake pedal acts like it is going to take off without my foot on gas.

I have a 2018 chevy silverado that has issues with the transmission slipping into different gears as well as hard violent jerking even on the freeway ,and I heard hard rumbling in my transmission burnt out with only 76,000 miles, it's like they're designed to go out.
