How Long Will A Buick Enclave Last? [ Reliability Explained ]

The Buick Enclave has come a long way down since 2018 as a reliable family vehicle. The midsize SUV can comfortably accommodate 7 people and has 3 rows. The wide plethora of integrations, visual appeal, and the lively engine of the Enclave make it one of the most outstanding picks in its class. In case you are willing to get an Enclave for your family, it’s worth considering the average lifeline of the car.

How long will a Buick Enclave last?

As a pretty durable SUV, the Buick Enclave can serve you between 200K to 250K miles. However, owners need to adopt sensible driving habits and ensure timely maintenance to make their Enclaves attain a long lifeline. Therefore, if you consider the average annual mileage to be around 15K miles, the car would last for 13 to 17 years. After this, you might have to fork out repair costs frequently, making the maintenance uneconomical.

The models that the brand has launched since 2015 have a better reliability rating and track record. So, you can cruise along for 200K to 250K miles with minimal maintenance and repairs. The earlier models had several engine and transmission issues. So, some of the older models might serve you for only 200K miles. However, if you are ready to shell out additional repair costs, you can make them last longer. Many of the older models had poor ratings for their reliability. As per Consumer Reports, many of these models received 1/5 for their reliability.

Even though the Enclave had some problematic years, it continues to be a robust family car. Some of the older models have already cruised along close to the 300K mile mark. Proper maintenance and responsible ownership ensure a better durability for these cars. To make the most of your Buick Enclave, use quality parts and change the oil as per the recommended schedule. Timely tire rotations and balancing, along with smooth driving make the car last longer.

In case you decide to tow, make sure to stay within the recommended limits of 1,500 lbs. However, the owners can tow up to 5,000 lbs. with the Trailering Package.

 What is high mileage for Buick Enclave?

For a Buick Enclave, you should consider 100K miles to be the high mileage mark. Even though the vehicle might have much more life in it, you might have to replace too many parts after the first 100K miles. Therefore, the chances of component failure are quite high.

Before you finalize your decision to settle with a used Enclave, carry out a complete assessment of its maintenance records and functional aspects. With proper maintenance, you can even go for a second-hand Enclave with the odometer reading more than 100k miles.

Scrutinizing these aspects will help you make an intelligent purchase.

  • Maintenance record: To ensure that the previous owner was responsible enough to carry out timely maintenance, check out relevant documents that the owner might still have.

In recent years, motoring experts and consumers have rated the Buick Enclave quite impressively. However, the older models are not too reliable, as they had more than a few issues.

Common problems in Buick Enclave

As a potential buyer, you should be familiar with the common issues that your Buick Enclave might have. Based on previous records, here are some of the common problems that these cars might have.

1. Transmission issues

It was the transmission problem that ruined the reputation of Buick Enclave. In some models, they did not go over 40 mph. Besides, the transmission refuses to go in reverse. GM had fitted the same transmission in many Chevys, which caused the same kind of problem in these cars. A manufacturing defect was at the root of this issue. Even when the owners replaced the transmission, the same problem continued to haunt them. So, if you are planning to go for a used car, check out whether it had any problem with the transmission, such as slipping, heating, or issue in going reverse. This issue crops up at around 80K miles. The models that the manufacturer launched up to 2017 had this issue.

2. Check engine light

When you notice the engine lights coming on, the problem might not be too grave. At times, a simple issue like a loose fuel cap might cause the dashboard light to illuminate it. So, you simply have to get the fuel cap tightened. Sometimes, you need to go for a replacement if the situation demands. Usually, you can diagnose this issue by forking out around $100.

3. Software problems

Your SUV might have software issues in case you skip regular maintenance. To ensure that this problem doesn’t bother you, get a software update and computer reset. This would keep away bugs from affecting the normal functioning of the SUV. In case the car experiences software issues, you would notice some strange behavior.

In Enclaves, the manufacturers integrate coolants that would serve you for the initial 100K miles. However, contamination in the coolant might require you to get them replaced earlier than this. So, make sure to inspect all the reservoirs and hoses. There might be cracks which can lead to the contamination of the coolants.

5. Electronics problems

Some of the Buick Enclave models have problems in electronics. Some of these glitches can cost you expensive, and you might have to shell out more than $1000 to get them fixed. Therefore, check the electronics carefully when you decide to go for a used Enclave.

While the statistics demonstrating the reliability of the older Enclave models don’t look appealing, you can settle with one of the more recent models. However, it doesn’t make sense to acquire one of these SUVs without an extended warranty. In the first five years, the Enclave depreciates by 54%.
