This is separate for VIN [XXX] I had to change dealerships because Beck & Masten South / GMC would NOT provide me with a loaner after being told I was on the list and I was next in line. I waited a month and drove to them and spoke with the girl who oversaw loaners. I explained I had severe safety issues such as front-end wobble which is related to transmission issues. And the oil consumption issue and oil light. Once again, I was re-assured the loaner program was indeed still active and I would be put on priority. Again to no avail I had wasted too much time with Beck & Masten. After months of this I found out I did not have to take it to the dealer I bought it from. So, I took it to Monument Chevrolet. I explained my concerns related to the front-end wobble which was very intermittent. And the oil consumption issue which I was very concerned with due to the year model and mileage of the truck. Also, the 75,000.00 price tag was really has me extremely upset... Monument Chevrolet treated me well. I had actually brought it in and called about the steering which was greatly affected by the severe front end wobble more than one time. I was told at first the oil consumption was pretty normal. Until I told them how much I had to add between changes. I have attached two work orders to this complaint. These work orders show what was done at 18017 miles and 18323 miles. The later work order was when the PICO test was done. Also, an oil consumption test was started once I picked the truck up. After I had driven it for 2077 miles and was bringing the vehicle back to Monument Chevrolet, as instructed for the oil consumption results, when a loud squeeling, then hard knock, power loss and I pulled over. I called Monument and was instructed if I could get it to start and bring it. I drove it to them while knocking and rough running. It has been in the shop for over 2 months for an engine replacement. 2077 miles after recall work! REFER TO: COMPLAINT XXX INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOI

This is in addition to the first report regarding my 2022 GMC Sierra SLT with 10-Speed Transmission. I had previously filed a complaint (NHSTA Tracking# 11728418.) regarding the OnStar and Internet quitting on me. Which was the Serial Gateway Module. I had reported that I was put off many times regarding a loner vehicle so i could get back and forth to my Oncologist for treatment of Head and Neck Cancer. And years of follow-up appt. with specialists Gastrointerologists and Cardiologist for serious issues incurred from 168 intense radiation treatments and Chemo. I had also taken my truck in for all scheduled maintenace intervals specified by the dealer and the manufacturer. "REPAIR ORDER GCCS504610" I had to leave it in the shop for 30 days for a defective Exhaust System, Radio, Charging Port, Remote Key Fob not able to unlock the truck so i could get in. And some other warranty/recall issues regarding my A/C blower and Seat cushion blower motor and Trailer Brake Switch, Fog Lamps running while daytime running lights were on - All Safety issues, My truck was @ Beck & Masten GMC for 30 days during these repairs, recalls and warranty. Will attach INVOICE 123532 to show consistant sheduled maintenance per GMC guidelines. Waited while this service was performed. "REPAIR ORDER / INVOICE 140542" Again my truck was back at Beck & Masten GMC (19 days) for the Serial Gateway Module and Radio not working AGAIN! Again, no OnStar, No Internet, No GPS. And, I reported the oil consumption and Add OIL light coming on; which was dismissed as idling too often (. I had to add 2 qts of oil between scheduled oil changes(The truck had only 13754 miles at this time) The LAST time I had anything to do with Beck & Masten GMC South was when I spent over months waiting on a loaner vehicle because I needed them to please look into still having an oil light coming on. And slipping and front end wobble just before the slipping/clucking and high RPM's that were dangerous- accident!!

I reported problems with my truck to Beck and Masten South GMC. I was put off a number of times with ridiculous excuses. My vehicle sat in the shop for a month to get my OnStar safety equipment repaired. I also had arguments with them regarding the oil light coming on and it burning excessive amounts of oil. I was told this was normal. I know better. Also, I needed to get it back into the shop for service and inspection for a squeeling noise under the hood. And to have them check the oul consumption. I was told it idle too often, and this was the reason oil was dissapearing. I was told they would put me on the loaner list so I could have means to get to my oncologist for cancer care. Well, I called numerous times because they never furnished a loaner for these issues I was told a third, then forth time I was next in line for a loaner so I could drop it off for repairs and recall work. After 8 months of these lies I finally went to Monument Chevrolet. Beck and Masten never intended to help me. Total I had tried and was told by newer service advisors, the manager, and GMC this would be remedied over 10 times in over 6 months. I finally gave up and moved on to never return to this dealer I had purchased two brand new GMC 1500 trucks from in a two year time frame. I did get my OnStar gateway repaired by replacement. It had stopped working again,shortly after getting it back. I kept getting put off. They stated it needed another Gateway for OnStar. I kept calling,and was told they would contact me ince it came in. I ended up troubleshooting the entire modem/router assy. I found inconsitant configuration parametrs. So, I reconfigured it all from start to finish after clearing the memory by taking battery cables off and allowing it to power down and clear memory. Then I did perform a reconfiguration and username/password change as well. I repaired it myself. The Onstar has never acted up again. These were my first issues. I had to take it to Monument Chevrolet for service

To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.
PE25001 · Loss Of Motive Power Due To Engine Failure
Opened Jan 16, 2025 · Closed Oct 23, 2025
Status: closed (inferred from source dates) · Engine; Engine And Engine Cooling:engine:hard Parts Internal/mechanical
On January 16, 2025, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE25001 after receiving complaints and field reports concerning engine failures in MY2019-2024 GM’s full-size truck and SUV T1XX platform equipped with the L87 6.2L V8 engine. These complainants alleged engine bearing failures resulting in knocking and growling noises from the engine’s bottom end and in some cases more severe consequences such as broken connecting rods leading to engine damage, or engine failure. If the engine fails during vehicle operation, the vehicle will lose propulsion, increasing the risk of a crash. On April 24, 2025, GM issued recall 25V-274 to address the concern with L87 engines produced between March 1, 2021, and May 31, 2024. GM cited the root cause as a supplier manufacturing and quality issues. GM’s recall remedy will be either an oil change to an oil with a different viscosity or engine replacement depending on the results of the remedy inspection procedure. To date, ODI has received 1,157 allegations of engine bearing failure. GM submitted 55,464 reports in total, with 29,752 unique VINs. ODI continues to receive allegations of L87 engine failures which fall outside of the scope of recall 25V-274. Based on GM’s recall, ODI will close this PE. NHTSA will continue to investigate complaints of engine failure outside the scope of recall 25V-274 as part ofEngineering Analysis (EA25007).
