Tucson versus Rav4
There are 2100 miles on the vehicle. It's been returned to the service department twice, on both occasions for the same problem. Regardless of driving mode, cruise or not, driving uphill the engine temperature symbol illuminates and remains on until one eases off the throttle. The RPM range is anywhere between 2100 and 2800.
On the first trip to the service department their diagnosis was "coolant level was down a little". They topped the system up. Three days later we are driving to NC, encounter a hill on the outskirts of the Great Smoky mountains and the light comes on. The circumstances were identical to the first occurrence. Returned the vehicle to the service centre, again, explained the circumstances and was assured they would work on it. We left it for an entire week. Five days into the diagnosis a mechanic left a voicemail message asking for a description of the symbol. A picture from the owner's manual had been shared with the staff at the time of dropping the vehicle off. When the vehicle was collected, the information shared was "no fault found". The team has been put on notice, if the condition occurs again, the vehicle will be returned to the dealership and it will remain there.
