See attached document for complaint.

3 Engine And Engine Cooling problem

Failure Date: 09/30/2022

Water pump prematurely failed. Upon self inspection, I noticed the coolant reservoir was below the minimum requirements. I asked the dealer to inspect, and they determined the cause was a faulty water pump. At around 50,000 miles, this water pump should not have failed under normal use. I am fortunate I self inspected, as continued use may cause premature engine failure due to overheating. Overheating would cause spontaneous vehicle operation failure during normal driving conditions, stalling the vehicle on a road or highway, putting myself and others at risk for impact.

4 Engine And Engine Cooling problem

Failure Date: 08/10/2020

Engine malfunction prevented the vehicle to engage and a significant lag. Correction of the failure has been attempted twice and a third attempt to correct malfunction is currently in progress with no movement as of yet. Gas tank has been drained and refilled and did not correct issue. Definitely not a gasoline type issue.
