NHTSA Complaint #11657969 — 2023 CHEVROLET SUBURBAN

Brand new 2023 suburban radiator ruptured at 14,000 miles. Radiator and hoses replaced April 2024 and the car has ongoing issues since then. Most recently the car has a strong coolant smell and the dealership states they cannot find a leak or source of the smell. I have worked with 2 different dealerships on this matter. I was told that the radiator was a “poorly manufactured part” when it originally ruptured. No safety warnings ever appeared even when the oil was dripping out of the bottom after the original rupture. Oil and coolant had mixed in the coolant reservoir and no warning light ever signaled. The most recent coolant smell poses a safety risk to my families respiratory system as the manufacturer states they cannot find the source of the smell and have tried to return to vehicle to me twice with the strong odor coming out of the vents. We have had the coolant reservoir flushed several times as oil remains in their, hoses replaced, and ongoing service visits for a year for the same thing since the original rupture in April 2024.
