A Shocking Dealership Quote

Taking a vehicle to an authorized dealership is typically viewed as the safest option for repairs. However, one 2020 Chevrolet Silverado owner was left questioning the integrity of his local GMC dealership after being told his truck required a full engine and transmission replacement, with a staggering price tag of $15,000.

Seeking clarity, the owner took his vehicle to an independent repair facility, Dave's Auto Shop, for a second opinion. What the technicians discovered there cast significant doubt on the dealership's initial diagnosis and repair practices.


The Diagnosis Discrepancy

According to Dave, the owner of the independent shop, the Silverado was originally brought to the dealership due to an unusual noise emanating from the engine bay. The dealer initially claimed the entire powertrain needed to be swapped out. Later, the dealership suggested a minor repair—replacing spark plugs and wires—for $800.

Upon inspecting the vehicle, Dave and his team were skeptical of the dealership’s work. Dave noted:

«The wires and plugs that the dealership had allegedly fitted looked worn, suggesting they either used old parts or failed to perform the service entirely.»

A More Precise Solution

After performing a thorough diagnostic scan and manual inspection, Dave's team identified the root cause of the noise. They discovered that an intake lifter on the No. 2 cylinder had collapsed. The truck's Active Fuel Management (AFM) system, which cycles cylinders off and on to save fuel, was identified as the culprit behind the failure.

Rather than replacing the entire engine and transmission, the shop recommended:

  • Performing a cam and lifter repair.
  • Deleting the AFM system to prevent future failures of this nature.

Significant Cost Savings

The total cost for the professional repair at the independent shop amounted to approximately $9,000. While still a significant expense, this was $6,000 less than the original $15,000 quote provided by the dealership. For a truck with 90,000 miles, the massive price discrepancy left the owner feeling misled by the dealership's initial assessment.
