The plastic radiator has cracked and is leaking coolant heavily. Truck still under powertrain warranty by GM is only offering to cover 20% of the $1,823 repair cost. I noticed it when stopped to get gas, the vehicle leaking approximately 1.5 gallons of coolant while stopped for approximately 3 minutes. This caused the vehicle to overheat and needed to add coolant just to drive to shop.

When I opened doors the fuel pump turns on, while I'm driving it shifts and runs funny and you hear popping noises. The gauges mess up and radio turns on and off. Like its being hacked.

Transmission shifts hard from first to second/second back to first. I noticed this about a week after purchasing truck. Shifts hard mostly in 2wd, not so much in 4WD or hauling/towing. Leaf springs and shackles have squeaked since day one of purchase. Engine oil pressure is at 12-15psi at idle and will not exceed 32-35 psi under normal conditions with or without a load. I've changed the oil filter and oil pressure sensor multiple times. There also seems to be a chirp/tick coming from the passenger side of the engine compartment. I've been trying to narrow it down for the last few weeks. Seems to be something going on in the engine itself or possible the ac compressor. Truck has 42,450 miles

Service stabilatract comes on before I start the truck still since the day I bought it the dealership does not know what's wrong. And since I bought the truck the tranny really bangs and clunks a lot it's annoying when trying to drive in stop and go traffic it gear chases way to much. It can't be good for the tranny life.

Transmission slips, transmission downshifts hard, transmission will have a loud thud when reengaging after taking foot off gas pedal in stop and go traffic, especially on the expressway. Thud can be felt in the cab of the truck. Electronic 4 wheel drive grinds when engaged in motion. 4 wheel drive grinds when turning even the slightest bit. Upon first starting vehicle transmission hesitates until temp reaches 125 degrees at least.

I purchased this truck new in November of 2018. It had 4 miles on it. My previous truck I owned for 10 years. A 2000 GMC Sierra, which I maintained meticulously. I sold it 452K miles on the original engine. Since I purchase the truck the transmission has shifted hard especially at low speeds. I won't write a review exactly like all the other transmission reviews, but they are same problems I am having. GM needs to rectify this issue due to the number of unsatisfied customers with a sub par product. I could have bought any truck I wanted, and I unfortunately bought a Silverado with a transmission that doesn't function the way a newer one should. Aside from the mechanical issues it causes, it is extremely embarrassing with passengers in the truck. It never fails, they all say the same exact thing...'what was that?'...... GM stand behind your product like we stood behind our hard earned money when we paid you.

Squeaking noise under box. Dealer took 2 months to get a replacement leaf shackle for left side. It did stop the noise. My transmission has a hard shift in gears when taking off and coming to a stop. Transmission seems to hang up shifting from low gear T a higher gear and does the same when coming to a stop. Seems to be getting worse. New truck, now has 21,000 miles but worst investment I have made switching from a foreign truck back to made in America. This hard shifting takes place when starting off or coming to a stop on any highway or street.

At approximately 15,000 miles I was parked in a yard and blocked in so I backed up on a small hill and the truck jerked badly for about 15 feet I thought it was the positive traction trying to catch on the grass but further into driving the truck I noticed it happening more and more in forward or reverse and in shifting into gears are at times hard. The last incident I was taking off from a red light today and around 40 mph it had a jerk/ hard shift, my truck is a daily driver and I have 44,000 miles on it currently. I am a hardworking american that purchased this $40,000 truck for dependability because I do a lot of driving and would love for some one to put a stop to this nonsense there are already so many complaints online about this 8 speed transmission jerking and snatching at random time can you all please make GM recall these and be held accountable for the junk transmissions.

The contact owns a 2018 Chevrolet Silverado 1500. The contact stated that the vehicle was experiencing transmission failure. After the contact went back and forth with the manufacturer and dealer (bill cramer Chevrolet Buick GMC, 2251 w 23rd St, panama city, fl 32405, (850) 250-1403), they settled on trading the contact's 2015 Silverado for a 2018 Silverado with the same transmission failure. The contact researched that Chevrolet was served with a class action lawsuit for the transmission. The manufacturer wanted the contact to go through the same process for diagnosing the 2018 model as he did with the 2015 model. The contact would have to make an appointment with the dealer and have a senior advisor from the manufacturer call him back. The contact wanted to know if he should file under the lemon law with his state's attorney general's office. The failure mileage was 0.

When driving on highway transmission surges/pulsates under light acceleration. When accelerating most often when vehicle is already in motion there is a extreme delay in shifting which causes a jerk at lower speeds or an delayed then hard shift at slightly higher speeds. Most noticeable in traffic.

Transmission clunks when slowing down

- Buford, GA, USA

Bought this truck brand new with 9 miles on it. (previously drove a Ram 1500). My first GM product I've bought in my life and I'm disgusted! I'm a victim of the 'transmission harsh downshift syndrome'. slowing down normally is clunky, nothing smooth about this 'automatic transmission' 6 speed btw. When slowing down abruptly (in stop N go traffic), transmission slams into gear while downshifting, feels like I'm being rearended. Took it to the dealership a total of 6 times, they say 'operating as designed'....yea right. My Ram never did this...talked to corporate on 2 separate occasions... 'there is nothing we can do' is what they tell me. Poor design, hate the truck, disgusted with GM. I'm now making double payments to get out from under it (because I'm upside down from buying brand new and GM thinks so much of their product to charge an arm and a leg and my first born) to trade it in on either a foreign car or back to Ram. GM doesn't care, rich billionaires crapping on the middle class, too many 'pencil pushers' creating 'new designs' to be fuel efficient and impress their bosses to make their bonus. News flash....we buy trucks not be fuel efficient, but to be manly and haul things and go off road and cary a few passengers while we're at it!! save yourself the hassle and dont buy a GM product.

This trucks transmission shifts whenever it wants to... I was driving 45mph and coasting to a red light when it downshifts hard but when the light turned green again and I pressed the accelerator I had no torque, like I was in 5th gear and should have been in 2nd. I pressed a bit harder and it downshifted hard again and was at 5K rpms! I thought it had an 8 speed transmission, but it sure doesnt seem like it. My truck was new and only has 5K miles on it. Unacceptable

Transmission slips, knocks, and grinds in some instances. No check engine light from these issues but spent 30K + and I having these issues at 13,500 miles.

When vehilce goes from 6 cylinders to 4 cylinders it shakes really bad and causes headaches at all speeds ! worse at higher speeds

- Spring Hill, FL, USA

The transmission slips or shudder, also has free wheeled when going down hill at slow speeds, also occurs in reverse, usually about 1 to 2 car lengths. Have returned to the dealer several times and been told that GM does not have a remedy. Had the service recommendation of a transmission flued flush done twice with different fluid installed with no change. Has been in the dealers shop for 3 weeks with GM looking at the problem, no solution in sight. No confidence that GM can fix the problem. This could develop into a serious safety issue.

Takata recall. While backing out of my driveway I heard a loud clunking sound coming from the under carriage of my truck. It stopped for a second and then did it again the clunking sound got progressively louder. I noticed the sound at low speeds, high speeds, going over minor bumps and big bumps in the road. Additionally, while going over big bumps I could hear what sounded like flexing and/or grinding metal coming from the rear suspension. I stopped the vehicle and proceeded to rock it back and forth and noticed the knocking/grinding sounds coming from the under carriage and the suspension. I got back in the vehicle and drove off and the sounds again started. I have infant twins that I was driving in my vehicle at this time and I became very concerned for their safety and mine. I took the vehicle to the dealership (since it is brand new and at the time only had 2-3K miles on it). They said "its a known problem in Chevrolet trucks" the paperwork they gave me after the "repair" stated" lubricate rear leaf springs and re-torque bolts" this indicates I had loose suspension components. The problem occurred again and I again took the truck to the dealership. They again stated the same repair and refused to provide any other remedy and also refused to replace the leaf springs. The same problem happened again. Again I took the truck to the dealership and again they refused to provide any other form of service to remedy the problem. My truck has less than 8K miles on it and it has been in the shop on 4 separate instances for the same suspension problem. The clunking and loose suspension noises have returned and I will be taking the truck in for the 5th time. This is unsafe, and my wife refuses to drive in my truck nor allow me to drive our children in our truck because shes concerned for their safety!
