Lets review local dealer calibration processes. We’ve all heard it before, the “DEALER IS CHEAPER!”, however it doesn’t mean they are doing it correctly.
Intro
Today, I’m following up on the 2021 Nissan Rogue I discussed yesterday. This vehicle has returned from the dealer, where they performed a configuration of the distance range sensor and a calibration. We’re going to review the process together to highlight the differences between our methods and common industry practices.
Missing Grill and Initial Observations
First, it’s worth noting that the grill is missing. According to the instructions, the area in front of the sensor (the grill) needs to be cleaned before starting. The absence of the grill raises a question: did this impact the calibration process? Let’s review the instructions and see what might have been missed.
Reviewing Nissan’s Calibration Instructions
- Four-Wheel Alignment: The instructions clearly state that a four-wheel alignment must be performed before the radar alignment procedure.
- Preparation Steps:
- Adjust all tire pressures to the specified values.
- Empty the vehicle.
- Shift the selector into park and release the parking brake.
- Fully fill the fuel tank.
- Check that coolant and oil levels are correct.
- Clean the distance sensor area of the front bumper grill.
Given these steps, let’s analyze the dealer’s work.
Dealer Invoice and Compliance Check
Here’s the dealer invoice (with identifying information removed for privacy). The dealer charged $358 for the calibration. This raises a question: was a four-wheel alignment included or provided for free?
- Tire Pressure: The door placard indicates 33 PSI for the front tires and 30 PSI for the rear. However, upon checking, the tire pressures did not match these values.
- Fuel Tank: The fuel tank wasn’t full, contradicting the instructions. Using weights to simulate a full tank is a debated practice, but in this case, it wasn’t done correctly.
- Vehicle Emptying: The instructions specify removing any luggage from the passenger compartment and trunk. This vehicle still contained items, indicating that this step was likely skipped.
The Broader Issue
This isn’t just about one dealer; it’s a widespread issue in the industry. When dealers don’t follow the manufacturer’s instructions to the letter, it compromises the vehicle’s safety and performance. We need to hold ourselves to higher standards to ensure every calibration is performed correctly and safely.
