I was driving on the highway at about 70 mph and the passenger side lower control arm where the ball joint sits broke. It messed up the passenger fender and tire along with the steering link. It also bent the upper control arm as well. The ball joints were replaced about 6 months ago.
Vehicle was determined to be unsafe to operate per inspection performed by Mike Maroone Chevrolet on 8/26/24 immediately after I purchased from Rocky Mountain Auto Brokers in Colorado Springs on 8/8/26. It was discovered by customer immediately after sale that bank 2 catalytic converter was restricted internally (after Rocky Mountain failed to correctly diagnose and repair 3 times before and after purchase). Customer discovered emissions warranty extension and took to Maroone Chevrolet. After warranty repair inspection of vehicle determined it was not safe for customer to pick up and drive vehicle and generated a report and video showing front suspension damage so loose that could cause crash and vehicle was towed back to Rocky Mountain for repairs. Rocky Mountain has failed to provide any documentation on these repairs and many subsequent repairs including transmission replacement after many written requests. Customer cannot verify if vehicle repairs brought vehicle back to a safe condition. Almost anll repairs by Rocky Mountain has failed resulting in missing bolts, bolts falling out after transmission replacement As well as failure of many CV Axel replacements documented in their own records. Extended Warranty Company also refuses to provide documentation of transmission replacement after they supplied the part (transmission) to Rocky Mountain for installation. Customer cannot verify if in fact transmission was replaced as it was painted black. Any warranty on replaced transmission cannot be verified and they also have refused to provide documentation or serial number verifying same after many written requests. Customer would like to submit a detailed letter and safety inspection report with further info and details in addition to this online form complaint as this is a complex case and additional info will further prove up these allegations. Some documents provided by Rocky Mountain are inconsistent with customer complaints and do not reflect accurate info.
The frame of my 2018 Chevrolet Silverado 1500 has rusted through to the point of failing Maine state safety inspection at only 41,000 miles. A licensed Maine inspection station identified structural frame corrosion and determined the vehicle is unsafe to operate. A Chevrolet dealer confirmed the frame rust and stated the truck must have rusted sections cut out and welded to be made roadworthy. The vehicle is available for inspection upon request. Safety risk: A rusted-through frame on a pickup truck is a serious structural defect. Frame failure while driving could cause loss of vehicle control, separation of suspension or drivetrain components, or catastrophic structural collapse, particularly at highway speeds or under load. The vehicle is currently unregisterable in Maine due to this safety failure. The failure has been confirmed by both an independent licensed inspection station and by a Chevrolet dealership service department. This failure is consistent with a known manufacturing defect documented in GM Technical Service Bulletin 19-NA-255, which acknowledges that the wax coating applied to the frames of 2011–2024 Silverado and Sierra trucks was improperly applied by a third-party frame supplier, causing the coating to peel and exposing bare steel to premature corrosion. GM has issued this TSB but has not issued a recall, and Chevrolet dealers are not consistently performing the repair. I contacted GM Customer Assistance to request goodwill repair and was refused; the representative also declined to open a case. There were no warning lamps or dashboard messages prior to discovery, as frame corrosion is not monitored by vehicle systems. The defect was identified visually during state safety inspection. I am requesting that NHTSA investigate this defect pattern and consider a recall, as was ultimately ordered for the similar frame corrosion defect on Toyota Tacoma trucks.
The contact owns a 2018 Chevrolet Silverado 1500. The contact stated that while driving at undisclosed speeds, the vehicle started shaking abnormally. No warning lights were illuminated. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 60,000.
We bought the truck new 2018 and started having trans issues and leaf springs popping. So, we took back to dealership and all they did was change fluid in trans and pump grease in-between leaf springs. I did get them to finally change passenger side leaf spring out, but that does no good when leaf spring they put on has the same issue. The leaf springs have to much gap in between each leaf. I told them to give me a 1,000.00 and I would go and have some made. That way, if I put a load on leaf spring it less chance they could break going down the road. Also, we have issues with radio that also did not get fixed by gm and still has the issue we can't use today. My truck also has the 6.2l engine that you guys have had complaints on. I will tell you that I'm not happy with what Gm is doing with these defected parts on these trucks. They are doing quick fixes to save them money on their screw ups and could get us killed. We are still having the issues to this day and they just brush us off. We pay a lot of money for these truck and Gm is ripping us off and costing us more money because we have to pay to fix their mistake, they should be fixing for free. All I want from Gm is get these issues fixed right and pumping grease in-between parts does not fix anything. We have to hold them accountable for these issues and make them fix it before it cost more peoples lives. I just want what I paid for and I did not get that when I bought it with these types of issues.
Both upper control arms have broken off at the ball joints. Also the cam and Lifters are failing and this vehicle has been maintained in accordance with the manufacturer guidelines.
Passenger side Upper control arm broke in two about to re-enter I75. Had been on I 75 and was going back on it when handling went wonky on Service road. You can see from the rust in the break this stamped part was cracked a while. Vehicle has not hit or run over anything since I have owned it. Had I been on I75 at highway speed it would have been deadly.
I purchased a used 2018 Chevrolet Silverado High Country (VIN: [XXX] ) on [XXX], with 24,375 miles. On the day of pickup, the truck felt like it was driving over rumble strips. Dimmitt Chevrolet flushed the transmission and used the updated Mobil 1 HP LV fluid. This worked temporarily, but the shudder returned. CarMax then sent the truck to Burke’s Transmission in Sarasota, where they replaced the torque converter. However, the shop declined to rebuild the transmission, citing its complexity. I later brought the truck to Cox Chevrolet in Bradenton. Despite clearly describing the shudder, harsh shifting, and driveline clunk, they told me the behavior was “normal” and refused to investigate further, stating, “We’ll look into it once the unit fails completely.” The symptoms have worsened. Harsh 1–2, 2–3, and 3–4 shifts are back. Shifting into Drive causes a loud clunk and forward lurch. Cold starts cause bucking and sudden stopping. I’ve replaced the tires, Bilstein 5100 rear shocks, and front suspension parts, but the problem persists. I signed on to a class action lawsuit against GM over the 8L90 transmission, but my claim was denied. This issue is well-documented and matches reports from many other owners. It affects drivability, safety, and long-term reliability. GM and its dealers have failed to properly address this known transmission defect. I urge NHTSA to investigate further.

Upper control arm weld broke around the top of the ball joint, a couple of months later other passenger side did the Exact same thing.
I purchased this vehicle from Galles Chevrolet in Albuquerque New Mexico as a certified pre owned vehicle. Couple of days after I noticed a vibration coming from the front steering and drivetrain I immediately took it back to Galles and they told me nothing was wrong with it and that the aggressive tires was what I was feeling. So I took it back and drove it for a couple of weeks and the vibration started getting worse so took it back again they rotated and balanced the tires and said it was fine. A few weeks passed and it started again took it back and told me tires were out of round and that was what I was feeling 21/2 months it sat in the back lot until they figured out who was gonna replace the tires. Finally got the truck back and it was ok until the new tires started cupping again and the vibration was back in total I took it in about 8 times in past 18 months for the same issue and to this day has not been resolved. According to GALLES CHEVROLET the technician stated that that was normal for a 2500 4 wheel drive truck with aggressive tires drives and assured me that there’s nothing wrong with the vehicle. Now look at the video and tell me if that’s normal for this truck For some reason it’s not letting me load a video of me moving the wheel up and down side to side where it moves about 3” with the steering wheel locked wheel is very very loose
I have an odd bounce/vibration front suspension both tires intermitting bounce on flat roads. It feels similar to drive on washboards raises on the highway. Suspension bouncing extremely fast. Transmission issues: Some owners have experienced jerky shifts, delayed gear engagement. On and Off Noise Click In dashboard.
Control Arm failure with tire separation from vehicle
Back in December of 2018 when I got my truck it only had a1000 miles on it and it has been down shifting hard it jerks hard I have reported it to the mechanic at the dealership at Mitch smith in Cullman Alabama and that said oh it’s supposed to do that well now it’s out of warranty and they said it needs this that and the other
leaf springs malfunctioned & yes its available for inspection. safety issues of cracking noise sounds like cracking in the suspension or axle. on 7/7/22 Lorenzo at Richland Chevrolet in Shafter, California confirmed & had it all day for inspection. no warning lamps or messages were provided. First appeared on 6/30/22. continental crosscontact LX20 P275/55 R20 111 t eco plus+ Tires are chopping & shredding safety & hazard issues are the tires can shred apart & cause an accident or death. on 7/7/22 Lorenzo at Richland Chevrolet in Shafter, California confirmed tires were having that problem & if there was a recall on them then General Motors would reach out to us. Then prior, on 4/28/22 during oil change & tire rotation service Lorenzo confirmed tires were chopping also. no warning lamps or messages.
A loud thumping noise comes from the rear axle area. The Chevy dealer claimed that the u-bolts that hold the axle to the leaf spring becomes loose and need retightening. I had the dealer re-torque the u-bolts but the noise still is there. The dealer claimed it was “normal” and offered no solution other than claiming a Tech Bulletin was issued instructing dealers to check u-bolts at service appointments. I brought my truck to a private repair shop and the mechanic noted that both rear leaf springs moved under the ubolts When the truck was rocked side to side. This is not safe as the axle can become out of alignment causing steering issues and excessive tire wear. The private shop quoted $1,100(est) to replace both leaf springs with aftermarket springs and u-bolts. The mechanic claimed that they have seen many Chevy pickups with this issue. I am asking you to please investigate this issue and instruct GM to repair this manufacturer defect.
THE FRONT PASSENGER SIDE BALL JOINT FAILED. IT IS A PRESSED FITTING AND IT CAME APART. THIS TRUCK HAS ONLY 25,000 MILES ON IT. NOTED A CLUNKING NOISE IN FRONT END, MOST NOTABLE WHILE BACKING .
I HAVE FILED A COMPLAINT ALREADY ABOUT MY 2018 SILVERADO1500 L, NEVER RECEIVED A RESPONSE ABOUT THE COMPLAINT FILED. MY TRUCK ROAD VERY ROUGH, IT HAD A BAD VIBRATION AND SHIMMY IN THE FRONT END. THE FRONT END WOULD NOSE DIVE WHEN BRAKING. THE TRUCK WOULD PULL TO THE RIGHT WHEN GOING AROUND A RIGHT CURVE. THE LEFT FRONT TIRE WAS RIDING ON THE OUTSIDE EDGE. TAKING TO LONG TO GET THE TRUCK TO STOP WHEN BRAKING. THESE COMPLAINTS WERE IGNORED BY THE GM SERVICE CENTERS, I WAS PRETTY MUCH CALLED A LIAR. THE LEFT SIDE FRONT TIRE EDGE WAS VERY VISIBLE TO THE EYE ON THE TIRE RIDING ON THE EDGE. CALLED A LIAR AGAIN. AT 16000 MILES I TOOK MATTERS INTO MY OWN HANDS. I BOUGHT NEW SHOCKS AND STRUTS AND HAD A CERTIFIED SERVICE CENTER PUT THEM ON. THE TRUCK RIDES WELL, NO MORE SHIMMY IN THE FRONT END, THE STEERING IS FINE GOING AROUND A RIGHT-HAND CURVE DOES NOT PULL TO THE RIGHT ANYMORE. THE TRUCK IS NOW BRAKING LIKE IT IS SUPPOSED TO. I HAVE A WARRANTY ON THIS TRUCK THE DEALERSHIPS DENIED THAT ANYTHING WAS WRONG WITH THE TRUCK. WHY WHEN I HAD THE SHOCKS AND STRUTS CHANGED THE PROBLEMS WENT AWAY. I KEEP THE GM SHOCKS AND STRUTS. I TOOK A STRUT AND PLACED THE ROD END ON A BOARD AND PUSHED DOWN ON THE TUBE THE ROD WENT INTO THE TUBE WITH HARDLY ANY RESISTANCE THEY WERE JUNK. I AM GOING TO MAKE A VIDEO DEMONSTRATING THE GM STRUT AND SEND IT TO THE NEWS MEDIA ALONG WITH THE PAPERWORK SHOWING WHERE I HAD TAKEN MY TRUCK TO THE DEALERSHIP SERVICE CENTERS. IF GM IS NOT GOING TO HONOR THEIR WARRANTY AND TELL THEIR SERVICE CENTER TECHS TO LIE ABOUT THE PROBLEM THE PUBLIC HAS THE RIGHT TO KNOW. I AM GOING TO PUT THE DATE THAT I HAD THE SHOCKS AND STRUTS CHANGED ON THE NEXT STEP. *TR
