2015 GMC Sierra 2500 HD
Mileage185,295Service Date12/5/2024Services Performed- Technician performed multipoint visual inspection, SCANNED THE VEHICLE SYSTEM ,checked Oil, Fluids, Belts, Battery, Charging System, Tires, Brakes , A/C, and Heating System. Our technician requested for an hour of labor permission to explore and diagnose from our customer in which it was granted and authorized by the customer. After extensive inspection and scanning, our technician diagnosed code P003A, this code is caused by erratic performance from the TURBOCHARGER. It seems a VARIABLE GEOMETRY POSITION SENSOR for the turbo has been replaced previously. A turbo module reprogramming is required when replacing turbo components. Therefore; our technician recommending to: Replace DEF REDUCTANT LEVELING MODULE, replacing variable geometry turbo vein POSITION SENSOR, and then REPROGRAMMING. The customer approved the job recommendation, then the technician ordered the parts, removed and replaced the def reductant leveling module by completely removing the reductant reservoir tank the fuel tank, removed and replaced the turbo position sensor, checked for a basic safety, started the vehicle, added DEF fluid as it was low, added coolant, let the engine run for a while, noticed the radiator is leaking from the top corner, performed a pressurized test, dignosed that the radiator has a crack in it but the customer does not want to take care of it now. The technician then took the vehicle for a road test drive, no issues except now he had to PROGRAM the turbo sensor. The programming was done successfuly.

2016 Mercedes-Benz E350
Mileage102,691Service Date11/15/2024Services Performed- Technician test drove the vehicle, performed multipoint visual inspection, connected the vehicle system to a live data scanner, checked Oil, Fluids, Belts, Battery, Charging System, Tires, Brakes , A/C, and Heating System. After vigorous inspection, the technician diagnosed that the cylinder #3 has a misfire, and he needed 2 hours of labor authorization to remove intake manifold and other components to access the spark plugs and ignition coils, and our customer granted us the authorization for diagnostic. With this approval, our technician got to work and diagnosed that the cylinder #3's misfire is caused by POOR RESISTANCE of two other IGNITION COILS, and it will cause an INTERMITTENT SIGNAL and misfire. Cylinder # 3 coil would try to compensate a lack of voltage, therefor; it will over heat causing EROTIC BEHAVIOR. The technician then called our customer to COMMUNICATE AND NOTIFY HIM OF HIS DIAGNOSIS AND FINDINGS, and he approved replacing all ignition coils. So the technician ordered the coils, removed and replaced them, scanned the vehicle system, the misfire disappeared, changed oil and filter, replaced engine and cabin air filters, topped off fluids, adjusted the tires air pressure, and reset the maintenance light. Tire rotation is not possible to scattered tires, then he took the vehicle for a road test drive, no problem now.

Mileage91,713Service Date11/11/2024Services Performed- Technician test drove the vehicle, performed multipoint visual inspection, checked Oil, Fluids, Belts, Battery, Charging System, Tires, Brakes, A/C, and Heating System. Our technician noted Under Interior/ Exterior, there is no CODES or CHECK ENGINE light or warning light on, headlights, horn, wiper blades, parking brakes, turn signals are OK, all fluids are OK.Under hood, engine air filter, belts, hoses are OK but BATTERY has internal issuses, and SPARK PLUGS are gaped out and need to be replaced (at almost 92k miles). Under vehicle, the control arms, tie rods, ball joints, and steering gear are OK but front and rear STRUTS/ SHOCKS need attention as the bushings are torn, front and rear differentials are OK, and transfer case is OK as well, front and rear brake pads and rotors are OK but there is an OIL LEAK from the oil filter housing that needs attention. Under the tire inspection, front two tires are OK but the vehicle needs two rear tires. So our technician recommends to replace oil filter housing, upper and lower intake manifold gasket (in order to access the oil filter hosing, the intake manifold needs to be removed, and when its removed, gasket can not be reused), add coolant, replace spark plugs, add 2 new tires, and replace front and rear and rear struts/ shocks.

2013 Ford Fusion
Mileage129,956Service Date10/24/2024Services Performed- Our technician did not want to test drive the vehicle due to the customer's concern of a "laud noise", So the technician racked the vehicle on a lift, performed multipoint visual inspection, checked Oil, Fluids, Belts, Battery, Charging System, Tires, Brakes, A/C, and Heating System. Our technician noticed the carboard under cover shield is gone , and the METAL SHIELD is hanging IN THE AIR and its loose while driving and causes a "loud noise" when hits a bump. Our technician secured it, and the customer asked for an OVERALL INSPECTION, and our technician did a through inspection for her , and noted his findings as follow: 1- Front & Rear brake Pads are at 3 & 4 mm respectfully. 2- Engine is leaking Oil from VALVE COVER GASKET, and the turbo system is wet with oil. 3- Spark Plugs are wet with Oil and contaminated. 4- Lower control arms front have broken Bushings, control arms come with ball joints. 5- An oil change is past due The customer DECLINED EVERYTHING EXCEPT THE VALVE COVE THAT IS LEAKING AND SPARK PLUGS THAT ARE WET WITH OIL. The customer chose to pay for this repair using 0% of SNAP FINANCING. So I sent her a link to fill out the credit application but after she got approved for $5000, she decided NOT TO use them , and stated she will pay for it out of her pocket. So with her approval, our technician ordered the parts, removed and replaced the valve cove gasket by removing intake manifold and other components, then removed and replaced the spark plugs, started closure of all components, checked for a basic safety, including leaking, turn the engine on, checked for any codes, test drove the vehicle, valve cover gasket leaking has diasppeared, spark plugs ignite well, no problem except those mentioned above that our customer Declined for now.

The technician diagnosed that the brake pads front and rear are very low to a level that really need to be replaced (wear mark), and the brake rotors already have a "lip" and almost "metal on metal" and beyond this it may damage the calipers if not replaced. Our customer gave the technician approval to move forward to replace both front and rear brake pads, rotors, and sensors. The technician ordered the parts (all OE), removed, cleaned up and replaced them, checked and reprogrammed and/ or re calibrate the sensors, the check light is disappeared now, test drove the vehicle, the brakes are fine now.

2018 Alfa Romeo Giulia
Mileage67,713Service Date10/16/2024Services Performed- Technician test drove the vehicle to understand the customer's complaint, performed multipoint visual inspection, checked Oil, Fluids, Belts, Battery, Charging System, Tires, Brakes , A/C, and Heating System. After the customer approval to do the job recommendation from the last visit, the transmission was removed to replace REAR MAIN SEAL. Once the transmission was separated from the engine, it was noticed that the rear main seal WAS NOT leaking rather OIL PAN is leaking. Then the transmission was reinstalled without any charge to the customer for labor, and started to following the trail of oil leak to see where the leak was coming from. The visual inspection showed that the INTAKE and TURBOCHARGER system were leaking oil. The oil that was feeding into the turbo and INTAKE was the fault of VALVE COVER PCV system. The oil feed and oil return pipe have THICK SOT build up. So our technician is recommending to: remove and replace gasket, and clean intake manifold, complete replacement of valve cover itself, remove and replace exhaust Manifold Gasket, remove and replace oil feed and oil return pipes. Our customer approved the job recommendation to fix his vehicle, and our technician ordered the parts, all were available for the deliver in 4 days except valve cover in 10 days. When they all delivered, our technician removed and replaced them, checked for a basic safety and/ or leaking, added oil, coolant, recharged the a/c, turn the engine on, checked for any codes or check engine light, none were observed, took the vehicle for a road test drive, no problem now, except the OIL PAN LEAKING that we communicated with the customer, and he stated he had warranty from the shop he had done the oil pan work previously.
