Consumer Description

Overheating light began flashing while driving 5/21/22. Drove to Napa Auto Parts and saw coolant reservoir was empty. Bought anti-freeze and filled reservoir. Upon arrival at destination, reservoir was empty again. Filled it again. Upon the next morning, reservoir was empty again. Took it to an auto-shop which found that the exhaust heat exchanger in my car has failed and is leaking coolant. Please see Applicable technical service bulletin, T-SB 0135-19. While the car is less than 96 months old, it is above 80k miles. I see this issue has been escalated in California, where the warranty is for 96 months and 150k miles. Want to report that the change in miles between states is disappointing. This issue is common and should be handled as a known recall, not just a known issue.
