While stopped at a stop sign my engine suddenly died, before restarting a low oil pressure light came on but went out immediately. I was approximately 40 miles from home when I got to my destination. The car was showing no signs of issues, no warning lights or errors. When I went back out to start it and head home it would not start. I had to pay additional expense beyond my insurance road side coverage due to the distance. I have had an independent mechanic going over the vehicle since it died. Starter has been replaced because it appeared to be the issue. (the original was bad) Once replaced while attempting to start it he found out the engine had locked up. I bought the vehicle March 30, 2026 & this happened on June 10, 2026. The vehicle had 132,344 miles on it when bought and 135,716 when it seized up. After looking through other reports I have found this to be a reported issue.
