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. …
The ignition switch shorted, a fuse shorted and these symptoms revealed a bigger problem. The holding area for the tire in the rear (does not hold a tire because of space issue) was repurposed by the manufacturer to mount the rear fuse box and amp. When the sunroof overflows or gasket allows moisture to build this area holds water. Unknown water source at this time but there is no drain for the water directed here to go out. Subsequently the electrical is exposed to water causing a fire hazard while driving or running. In my case it melted various relays and wiring harnesses but I was able to find before the fire started. This is also in the vicinity of the fuel tank causing an extreme hazard. When researching I found this model car there were many that had reported it. This could have been extremely dangerous fire while operating and is completely preventable with small alteration. …
Trunk flooded with water due to insufficient drainage. Factory radio amplifier and vehicle fuse box are covered in water as well as aftermarket amplifier I've installed. I have parts for inspection if needed. My safety could be at risk if this causes a fire hazard, but I am unsure if that could happen. Other safety risks to myself and other drivers could be present if tail lights stopped working or engine suddenly shutting off. These as well as other things could suddenly stop working if the fuses blow or corroded from water in the fuse box. This is a common problem amongst owners of this vehicle, and has cost large amounts to replace electrical components. My vehicle has not been inspected. I took the vehicle home and parked it after finding water in the trunk. No warning lamps or messages appeared. Symptoms prompting me to check started with radio suddenly going quiet. …
I've been experiencing my acceleration and brake pedal engaging without my intervention. While driving , a sudden unintended acceleration will occur followed by the brakes engaging by itself. With the sudden acceleration, fail to accelerate, & delay stopping, all of these factors can cause danger to both the passengers in the car, including myself & others on the road around me which is a very big safety issue. In addition , with the problems i was experiencing & engine light being on my display i took the vehicle to be inspected by Don Mealey Chevrolet in Clermont, Florida 347811 on March 31st 2023 . The DTCs Read showed Active, failure code0x00: P0700 Transmission Control System(MIL Request).
The contact owns a 2018 Chevrolet Camaro. The contact stated that a manufacturer defect had caused moisture to seep into the trunk compartment. As a result, water had leaking into the battery compartment which had caused the vehicle to shut off while driving. The vehicle was taken to the dealer where the defect was confirmed, and the contact was provided an estimate for the repair. The manufacturer was notified of the failure. The vehicle was not repaired. The failure mileage was unknown.
Manufacturer default in the trunk. Water is getting into the trunk causing water to fill up in the battery compartment. Thus, shutting the vehicle electrical system down completely. After researching, I contacted GM who stated that they are unaware of this issue, although many people who own this type of vehicle have had this issue occur.
Engine began to shudder as if the engine wants to turn off. It can also feel as if there is some issues with the drive axles. It leads to loss of power of the engine. The loss of power goes away upon shutting the engine off and turning it back on however the check engine light remains on and the error code p0420 displays on the reader.
-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
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.
The vehicle has been taken to the shop 3 times, for service rear axle issue. now has a power steering fault code which when it came on made the car hard to control luckily i was only going 20 mph. the car looses power as well
