On January 16, 2026, the Office of Defects Investigation (ODI) opened Recall Query RQ26001.  This investigation was opened to assess the remedy effectiveness of Recall 25V-274. ODI has received complaints alleging engine failure in vehicles after the recall remedy had been completed, whether that remedy involved an oil viscosity change or a complete engine replacement. General Motors (GM) issued Recall 25V-274 to address concerns of engine failure in the L87 engines produced between March 1, 2021 and May 31, 2024. GM cited the root cause as a supplier manufacturing and quality issue. GM’s recall remedy for Recall 25V-274 consisted of two different repairs, either an oil viscosity change or an engine replacement, based on the results of the remedy inspection procedure. ODI continues to receive reports of engine failures after the completion of the recall remedy. To date, ODI has received 499 complaints alleging post-remedy engine failure in vehicles subject to Recall 25V-274, 473 of which involved an oil viscosity change and 26 a complete engine replacement. Additionally, ODI has received 191 reports of L87 engine failures in engines produced after the production period cited in Recall 25V-274. GM reported receiving 6,953 complaints of post-remedy engine failure. ODI is opening this Engineering Analysisto continue investigating complaints of post-remedy engine failure. ODI is expanding the scope of this Investigation to include engines produced after the production period cited in the recall.

The engine started making a ticking noise and getting a little louder while driving to dealer where I had purchased the veichle and had it serviced as called for . They had me leave to check it out , they called me 2 hrs later and said it would need a new engine and it had a spun crankshaft bearing and would be 3 weeks to get the new engine . They said my warranty would cover the billing . I’m presently waiting to hear from them . They told me that the new engine would have a warranty but minus the 31615 miles that my odometer reads now ?

The engine has been using atleast 1 quart of oil every 2000 miles. This is put my maintenance cost way above the estimated maintenance cost projected by the manufacturer This oil usage is also causing premature engine wear as it's a quart low every 2000 miles. Dealer responses was this is normal for this engine. I went back and forth with the about estimated maintenance cost and ofcourse there responses was it estimated, well that's a very inaccurate estimate or willful lie. Idk just not happy about it.
