I'm beginning to have similar problems with the 6.2 ecotec3 engine that gm has known problems and hasn't recalled them. Dealer indicates metal shavings from the main motor bearings. Just like others I will experience a total motor failure at anytime. This will be catastrophic if motor fails and shuts down. I fear I will be rear-ended or not be able to get out of harms way. This has happened to many with the same motor. Why would there not be a safety recall on a known safety issue. Others affected have been injured even killed because there vehicle just stopped in the middle of a roadway. I currently fear for my families safety and cannot simply opt out of a vehicle with only 18,000 and thousands invested. Instead it sits waiting for the right thing to be done. To be repaired to safely use. Thank you kindly.

I took my truck in for an oil change on 5/25 and 12 miles after words, my truck was thrown into reduced engine power mode, which dropped my speed unexpectedly as I was driving. Luckily, I was in a residential area so that did not affect my safety, but there is potential that someone could have this code come up on the highway and have their vehicle unexpectedly throttled in regards to speed. The reduced engine power mode was the result of a code related to an electrical issue that ended up being the coolant control valve for the engine. I took it to a Chevrolet dealership that did the oil change, and they inspected it and determined that that part was faulty And would need to be repaired. The problem comes intermittently because The dealership drove my truck some and the issue would occasionally go away. As the part needed is on a seven month back order, the vehicle is available for inspection if needed.

Problem started while driving on the highway, I was speeding up from the ramp to merge into the highway. As I got to 62 mph the dashboard started blinking that i could only go up to 62 mph max. Cruise control was not on. I drove to my destination at that speed with the message on the dashboard. I arrived at my destination, parked, turned it off, a couple of hours later turned it on to drive again. At this point, the dashboard message was that I could only drive it max speed 42 mph and "service tire monitor system" I towed to my mechanic given i could not drive at that speed on the highway back home. The mechanic said it was time for a brake change and that might be the issue. He changed all the brake pads and rotors and the truck drove fine again for less than a week. As i was getting on the highway, the truck started to jerk like it wanted to stop as i was speeding up, i was going 45 mph. There was a clanking sound coming from the engine. Then multiple things started flashing on the dashboard; check engine, traction control, messages reading "service parking brake" and "service ESC" I turned the truck off for a couple of minutes on the highway shoulder. Turned it back on, the same messages were still on the dash. I again could only drive it max in the 40's mph. The faster I tried to go, the more heavy and forced the truck felt. I had to park it over night in a parking lot. The next day i scheduled an appointment with a mechanic in town who checked it and said i would be needing a new engine, that he had seen this same problem a couple of weeks ago on a same truck. He quoted me $9K.I towed the truck back home and had another mechanic come take a look at it, he was getting the codes 0P50D and P0304.He exchanged the 4 cylinder for the good 1 cylinder to see if the codes would change from #4 to #1 and it did not. He said the issue was internal at that point and suggested I go take it to the dealership under the warranty. Its not under warranty, it ended at 60K miles and I have 80K now.

Around 35k miles had an engine lifter fail and needed to be replaced, covered under warranty. 07/2023 - Had front pads/rotors replaced by Chevy dealer and had loud squeaking ever since. Contacted dealer and was told they are new pads so will just need time to break in. Contacted the dealer again in Sept.Oct. 2023 and brought vehicle in for service for noise concern. They informed me the noise is coming from the rear brakes that was reported as 60% life two months prior. They replaced the rear rotors/pads and noise persisted. Brought vehicle back to dealer in December, they performed a serviced but was ineffective. In March 24 started getting some vibrations when stopping. Brought vehicle for servicing, stated there are rust spots on rotors but everything is wearing fine so this will not be covered under warranty. Also that they do not warranty sounds due to pads can have more metallics then others and they cannot determine which ones do not. I looked under forums and GM Pads seem to be a common issue with noise. My truck was perfectly fine before these brake products were installed and I would like GM to be held accountable for there inferior products leading to loud break noises and violent vibrations while braking !

Check engine light came on, I plugged my code reader in and was given P0498 ERROR CODE. Upon doing research and calling around to 3 different Chevrolet service centers I was told that it is a know issue with the fuel pump control module on all gm trucks. I am part of a truck group of over 150 and 85 of us has had this issue and all are currently waiting for the part to come in which is back ordered over months. Why has there been no recall and service bulletins yet if all 3 of the service managers agreed of the known issue.

I purchased my vehicle from Southern Pines NC and at the time it had 12k miles on it. At about 40K I started having transmission problems. It would hard shift in 1st and 2nd gears. It also would not go into reverse. Hendrix Chevy had my vehicle multiple times attempting to fix things. Telling me it was not the transmission etc etc. My power train warranty expired at 60K. I have asked for my complete service records multiple times. I have paid out a lot of money due to it "not being the transmission". The last time it was there the manager Matt took it home and said the changed the transmission fluid which was very dirty. Almost trying to say I had done something to make it that way however in the service history they had it almost the entire month due to issues. I got it back and my brakes went out while driving. I was able to cost to a stop. I was at my limit. I called Matt and said come and get this vehicle. I want Chevy to take it back. They kept the vehicle for almost 2 weeks. Matt said he personally drove it home and it was fixed. I picked it up and I have not had any issues for about 8 months or. Now my power train warranty is expired and my vehicle is again doing the same things it was when I took it in at 40k. It now has 85k. It is hard shifting in 1st and 2nd. It is rolling when in drive. I also have had many body parts that have come off etc. I called Chevy today to again get my service records. I stil have not gotten them. I just want a reliable vehicle. I feel like I have not had a reliable vehicle from day one. I want them to take this vehicle back and I want a Toyota hat is comparable in cost of my truck in its new form. Can you help me?

Notice the engine temp was rising, had notice I was slowly losing coolant in my overflow tank. Then while driving it started making noise that the engine overheated need to idle vehicle then as I pulled to a stop light the rims bogged down the whole vehicle shut down The radiator has a small leak in the plastic reservoir on the driver's side of radiator. Could have cause a big problem if I was in traffic when it shut down cause I had no control to turn the wheel or anything else once that happened.The vehicle got extremely hot very fast.
