A routine stop at a Take 5 Oil Change location in McKinney, Texas, left a local realtor facing roughly 3000 dollars in vehicle repairs after her Mercedes-Benz began overheating less than 90 minutes after service.
Gibelly Chevez documented her frustrating ordeal on social media, explaining that she visited the shop in mid-August for a standard oil change and agreed to an additional coolant flush.

After attempting to contact the closed shop that evening, she returned the next day, where an assistant manager offered another flush but ultimately advised her to seek a formal diagnostic report from a full-service mechanic.
Dealership Diagnosis Points to Coolant Issues
When Chevez brought the vehicle to a Mercedes service center, a diagnostic check revealed that the car was in critical condition and running on the wrong type of low coolant.
The dealership report explicitly noted that pressure testing showed no physical leaks, but pointed out that incorrect fluid had been installed in the engine system.
Despite presenting the diagnostic findings to Take 5, Chevez stated that the company's insurance ultimately denied liability for the damage, arguing that the facility uses a universal coolant.
