ELECTRICAL SYSTEM
On three separate instances (two after paying $3,000 to "fix" it) my 2021 Trailboss is flashing warnings of: Park Assist Off, Steering Assist is Reduced Drive with Care, Service 4WD, Service Trailor Brake System...all while driving down the rode and losing all gauges/flatlining and no fuel warning engaging (had a 1/2 tank). The Chevrolet Dealer claims it's not producing a code (Thankfully I recorded the evidence)...Truck has just over 40k miles and has been driven with care. **Pictures are all while driving down the road** Serious electrical and SAFETY ISSUE and it needs to be RECALLED and addressed!

SERVICE BRAKES
Started having a rubbing sound in rear end of vehicle. Took it to dealer. Brake calipers are a issue on this model and dealer says, “ found updated rear brake calipers with deflectors to help with dirt in rear calipers/not covered under warranty customer pay expense”, they are replacing rotors under warranty that got worn out. They want me to pay $2400 to purchase and have the “updated brake calipers” installed. If brake calipers are updated then that means there is a known issue with them. Spoke with the manufacturer and they said too bad.

ENGINE, POWER TRAIN
Vehicle began to shudder on the highway, managed to pull off at next exit and drive to nearest gas station approximately 3 miles away from the highway. Vehicle was towed to neared GM dealership. Dealership has determined that the fault is caused by a failed or multiple failed Camshaft Lifters inside the engine. This has been reported to be a common issue with the GM 5.3L Engine with no active recalls. The vehicle shudder began on a highway during construction where the highway was restricted to one lane. There was an accident with bumper to bumper traffic where an ambulance required way. The vehicle was not in stable condition and could have caused safety risks to other drivers on the high way as well as my passengers and myself. There were no symptoms prior to the vehicle shudder, the Check Engine Light did not come on until about 3 miles of driving closer to the gas station. The Service is being warranted by GM. There are active GM tickets open. Vehicle is being serviced by Stickland Cadillac Buick GMC Chevy in Brantford Ontario Canada

ENGINE
July 18th 2022 16,059 miles engine issues again. This time was 21 hours from home. Cause reported was oil pump failed. New engine to be installed. Asked if previous engine issues was resolved aka lifters but couldn’t get a 100 precent yes or no. Truck now has little over 30k and from time to time makes noises like lifters chattering. I pray it’s been addressed but fell it may still fail again. Just will it be under warranty or out of warranty next time.

POWER TRAIN
The truck lunges sometimes, and will jerk shifting, also at variable speeds the truck will feel like it is "riding over rumble strips at a low speed" at variable speeds 30 MPH to 70 MPH. It makes for an unsafe feeling having the vehicle lunge unexpectedly, and the shuddering on the highway causes alarming panic, and reaction, and a feeling of delayed response from the accelerator. Yes, everyone says it is a known GM issue, but nothing will be done, unless I contact a lawyer. No No warnings, or lamps of any kind.

SERVICE BRAKES, STEERING, UNKNOWN OR OTHER
While parked I turned on the truck and got service sec warning and power steering failure. Brakes barely worked and wheel was locked. After restarting the car three times it went away and truck became driveable. Took it to a dealership and they said there’s nothing they could do as a code didn’t pop. Seems unacceptable as my family is consistently in the car and if it happens while driving could be extremely dangerous

ELECTRICAL SYSTEM
I bought this vehicle brand new off the lot in 2021. Truck hasn’t had any problems until this year. Every few weeks it will randomly just not want to start, I’ll usually check the battery and the battery will be completely drained. I can’t figure out what is causing the battery to drain like this, but something needs to be done as I have literally been stranded places due to my truck just deciding not to start randomly. Today i’m having this exact problem, my trucked was parked overnight in my garage and I went to go to work this morning and once again the truck won’t start and battery is drained. All my doors are shut and no interior lights are left on.

ENGINE
I was driving one day and my truck started to misfire. I figured since it had 95,000 miles it was time for a tune-up. So I took my truck to the Chevrolet dealership and they originally quoted me $2,200. The rep and mechanic said they have seen many trucks just like mine having the same issue. They said it starts with something called a “rocker arm” breaking and then that leads to more severe issues. After a month of my truck sitting they came to me and said it will cost $8,100 to fix it. Basically they replaced the engine. My complaint is I’ve had many vehicles and none of them needed an engine replaced after only 95,000 miles. I later found out that the engine that’s in my truck is a 4 cylinder which is a very low power/small engine which is expected to handle the weight of the truck along with towing. I just believe it was a poor design and that engine is ill equipped for a truck and the dealership/manufacturer should bear responsibility for that.
