My sister bought a new 2016 Jeep. At 3500 miles it had used 3 quarts of oil. They filled it back with oil and told her to bring out back after 500 miles. She did and it had used a quart of oil. They filled it and again told her to bring it back after 500 miles. Again it was a quart low. They called Chrysler and was told to put a new motor in. After putting in the new motor my sisters son in law came over, poped the hood, and noticed missing motor parts. They looked and saw the parts in the back seat. The took the Jeep back to the dealer where they installed the missing parts. Chrysler by rights should have given my sister a new Jeep. Replacing the motor before she even makes the first payment means she is paying a new Jeep price for a used Jeep.
