NHTSA Complaint #11636704 — 2021 GMC YUKON XL

We were driving on the interstate outside of Chattanooga TN when our car went into neutral while we were in the left hand lane next to a 18 wheeler. My husband was driving and we have our four children and dog in the car. We lost acceleration. My husband was successful in getting us off the highway and onto the shoulder. The car started again and we tried to make it to the next exit when it went into neutral again and lost power. This was on [XXX]. We had it towed to the nearest dealer, Integrity Motors. They called us and said that it threw a rod and that the engine was broken and the whole engine would need to be replaced. After replacing the engine (it took 2 months) we picked the car up only to have the engine light come on. I took it to Autozone where they ran the codes and told me that the fuel injectors were bad and possibly the intake manifold gasket. I called Chattanooga and they told me that I should take it to the nearest GMC dealer. Parks GMC in Greenville inspected the car and we had to put in 8 fuel injectors. I have documentation of all of these issues. There was no warning light or any warning that our engine was about to shut down. We could have been in a serious wreck with the 18 wheeler with possible loss of life or injury. We have had significant financial loss.
