Buick Excelle underwent a comprehensive inspection, with only one issue requiring attention

A Buick Excelle came into the store for engine maintenance. The paint looks very new, but the overall design of the car is quite old. When I checked the frame number, it turned out to be a 2017 model Excelle with a production date of July 2017.

Although the production time of this Envision is early, the total mileage is very small, only 23000 kilometers, as shown in the following figure. The car owner said that she doesn't have many opportunities to drive and usually travels by tram.

First, check the tires. All four tires are original factory tires, as shown in the following picture. The number 1717 on the side of the tire indicates that the tire was produced in the 17th week of 2017, more than 8 years ago.

Tires belong to rubber products, and although they have a short driving range, they have been used for a long time, resulting in significant rubber aging. Looking at the front tire shown in the picture, there are many aging cracks on the tread and rubber blocks have fallen off. The driver said this is because the front wheel belongs to the driving wheel, and the friction between the front wheel and the ground is greater, resulting in greater tire wear.

Compared to the front tires, the tread also has cracks, but the wear is noticeably lighter than the front wheels, and the tread pattern is still very deep.

After fully raising the car, it can be seen that there is no large protective plate at the bottom of the engine and gearbox, only a small protective plate on one side of the engine.

The front part is a full frame subframe, which is relatively sturdy, and the lower support arm is made of single-layer stamped steel plate. After checking these components, there are no problems.

After checking the front chassis without any problems, the technician unscrewed the drain screw and drained the old engine oil.

Looking at the middle part of the chassis, there are no protective plates or armor, but there are no signs of rust, indicating that the Envision body has done a good job of rust prevention. There are scratches on the bottom of the middle exhaust pipe, and a missing piece of insulation tile on the upper part. The technician said this was caused by scratching with the ground, but fortunately other parts are normal.

Looking at the rear suspension, it is a multi link independent suspension type, with a 44 liter fuel tank at the front of the suspension and insulation tiles near the exhaust pipe.

Check the rear suspension on one side separately, mainly focusing on the condition of the rubber sleeve, and there is no problem.

Overall, this Buick Excelle is in very good condition, possibly due to its short driving range. The engine is a classic naturally aspirated L2B model, and the gearbox is a 6-speed automatic transmission. There are basically no problems, except for one issue that needs to be noted, which is that the two front tires need to be replaced!
