8. Incorrect Fuel Gauge

Most of the Buick models have a problem in common, and that is an inaccurate fuel gauge.

This is not good, as you need to be sure of the fuel level in your vehicle before embarking on a long-distance journey.

Most drivers said the fuel gauge needle does not show fuel signs when the tank is not full.

However, one of the reasons for this problem is the failure of the instrument cluster. This is likely to be caused by the electrical system failure.

A faulty fuel sensor that causes tank corrosion and leads to inaccurate readings can also be the cause. However, it is advisable to change the sensor if you notice that it is the leading cause.

9. Transmission Problems With Error Codes

The transmission system failure is common to the Buick Rendezvous models. However, several error codes will come up, each of which has a different meaning.

11. Gasket Leakage

If you plan to own a Buick Century model, you may have to cope with the solenoid failure.

The most common issue of this model is with the seals and intake manifold gasket.

Experts have discovered a reaction of the General Motor Dexcool coolant with the gasket, leading to the leakage.

Drivers complaining about this problem have been advised to find a quick solution. If left unattended, it could cause severe damage.

You may need to change the gasket, and a competent mechanical expert can do this.

12. Stretched Timing Chains and Window Assembly Failure

Window assembly failure and stretched timing chains are two common problems that usually affect most Buick models.

For instance, there is no trace or sign that there is about to be a failure of the window assembly. The windows suddenly fall into the frame, and its plastic part breaks down.

You are likely to get the windows replaced by the manufacturer, and this would cost you around $450 for each window. This does not stop it from happening again, as the assembly remains the same.

The Buick Enclave models have the Stretched Timing Chains problem. Once there is a stretch of the timing chain, it leads to combustion problems.

A timing chain is a crucial connection between the crankshaft and the camshaft. It is situated in the front of the vehicle, and the chain runs through pulleys, gear, and guides.

The responsibility of a functional timing chain is to keep the engine timing in check. The timing chain coordinates the activities of moving parts, such as pistons and cylinders.

Timing chain slack can be caused by a faulty chain tensioner or stretched chain.

This problem can also make the pistons bend the valves and damage the car engine. You can solve this issue by ensuring a regular change of oil from time to time.

This model’s estimated repair expense for a stretched timing chain is usually around $3,200 and $3,400.

If you fail to resolve this stretched timing chain problem, it could cause damage to other components, such as O2 sensors, cylinder heads, and camshaft position sensors.
