2018 Chevrolet Camaro

I am writing to express my frustration and concern regarding the well documented transmission shudder issue affecting my 2018 Chevrolet Camaro LT. My vehicle currently has only 29,800 miles, yet it has begun experiencing the same symptoms described in Technical Service Bulletin (TSB) 18-NA-355. The vehicle's RPM gauge fluctuates noticeably, moving up and down while driving, and the car develops a significant shudder or vibration that can be felt throughout the vehicle. The issue is most noticeable during steady acceleration and cruising speeds. Not only does this affect the driving experience, but it also raises concerns about the long term reliability and safety of the vehicle. What is particularly troubling is that this problem has been widely reported by numerous Chevrolet owners and acknowledged by General Motors through TSB 18-NA-355. Despite the widespread nature of the defect, there has been no recall issued. As a customer, I find it difficult to understand why owners are expected to bear the financial burden of repairing a problem that appears to stem from a known manufacturing or design issue. A vehicle with fewer than 30,000 miles should not experience transmission problems of this magnitude. Many owners face costly repairs, including multiple transmission fluid exchanges, torque converter replacements, and in some cases transmission replacement. These expenses can be significant and create a negative ownership experience. General Motors has built its reputation on quality and customer loyalty, but issues like this damage consumer confidence. When customers encounter known defects and are left responsible for expensive repairs, it discourages future vehicle purchases and harms the brand's reputation. Many current owners, myself included, are reconsidering whether we would purchase another Chevrolet vehicle in the future. I respectfully request that General Motors review this issue and consider issuing a recall or extending warranty coverage for affect

Major steering issues car loses the power steering randomly, will be driving around a corner and the car won’t turn at all very dangerous car only has 13,000 miles on it

Lifter collapsed. Car had new gm lifters put in with a new camshaft in august of 2025 they have about 5k miles on them and failed they are the gm high performance lifters

Steering wheel is hard to turn

Car has a power steering problem and car sensors are not working. Tire sensor, ac sensors, etc.

Loss of power steering, particularly mid-turn and at low speeds. Steering becomes very difficult and greatly increases risk of crash. I have had several instances where my power steering will go out mid-turn and the steering wheel becomes almost impossible to turn. I have nearly t-boned another car due to this issue. It has also nearly caused me to drive off the road into a ditch. I did not notice any warning lights on the dashboard, but it's hard to say because I was focused on not crashing the car.

Getting shift to park message when car is already in park preventing the car from completely turning off. Leaving the car partially on draining the battery- Failed transmission controls

I lose power steering randomly. When this occurs I get a service rear diff message on my dash, the fan motor cuts out, and gauges like the speedometer and tachometer go to zero. I took it to a dealer because I saw there was a recall for the exact problem I'm having with power steering, but I guess it's VIN specific and my car is not included in the recall. They also told me they couldn't get it to reproduce the symptoms I was talking about but after I left 10 minutes later it did it in a Walmart parking lot. I got it on video. This has caused one almost serious accident and multiple minor ones, and I can't afford the expensive dealer diagnostic fee and repair. I don't feel safe driving with it. I'm confused why I have the same make model and year of the recall but mine's not included. I called GM and the lady I talked to just kept repeating how my van wasn't included in the VIN specific group, and offered no help other than to go to a dealer and pay them to fix the same problem that is covered by other cars of the same year, make, and model. I asked her if it was possible that maybe their VIN groups should be expanded, especially because it's an 8 year old car and the recall just happened like 6 months ago, so maybe they didnt have all the data or info when they made the group of effected vehicles, and she hung up on me. Please help.

Loss of power steering assist

The power steering failed on June 17th, 2025 At approximately 3 PM. The system has been replaced by the local dealership so it is not available for inspection (dealership did it's own evaluation/inspection and determined the need for replacement). The vehicle was being driven when the power steering failed, so my safety and the safety of others on the same roadways was put at risk (fortunately, I was only about 1.5 miles from home). Prior to replacing the necessary parts, the local dealership reproduced and confirmed the problem was present (documentation to follow). The local dealership inspected the vehicle. As no accident occurred, local law enforcement and insurance representatives have not been involved. No warning lamps or messages or other symptoms of the problem occurred prior to the failure. A warning message was displayed once the failure occurred.

The oil pump failed which caused to replace the engine as the oil pump is located in the engine. Pieces of metal from the oil pump failure went into the engine which could cause serious crash.

No warning signs other then the oil pump went to zero during a drive on [XXX] . I have an invoice and emails going back and forth with GM.

Side object detection module was shorted out due to water intrusion. Caused by faulty manufacturing material. Caused vehicle to shut down and unable to restart. Large safety concern Warranty company refused to cover the issue.

[XXX] Here is a link that explains this further. The oil pump on this vehicle has gone out with 11,000 miles on it. This a known problem from GM and they will not fix it. I am being told my car is out of warranty so no luck. This is not right. The pump should not go out that quick. I am being thrown to the side because I cherished my GM vehicle and didn't drive it as much as others. It risks blowing up the motor due to their faulty part. It isn't safe. [XXX] Here is another link to GM's site explaining that they know it is an issue. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

-Convertible back window popped out on right (passenger side), seal failed. A Chevy repair shop acknowledged the recall but said they did not have technicians trained & were limiting repairs due to COVID-19. -Engine shudders, loss of power -Electrical failure of USB connections in middle console

The car had a partial oil pump failure where oil pressure dropped 30% in 2 days at 14k miles while under warranty. car was taken to dealership where I was denied service. they said I put the wrong oil in it and "installed the oil filter wrong". I cant even think of a way that is possible. they changed the oil and filter and pushed me out the door. Tt 18.6k miles the pump completely gave out and had zero oil pressure while driving, which destroyed the engine. A quick search online will yeild plenty of instances where the 18+ camaro ZL1 has had oil pump falures.
