Suburban widely known as Chevy or Chevrolet Suburban, is a full-size SUV series solely owned and built by The Chevrolet Motor division of General Motors. In 1935, Chevrolet introduced the first Suburban model in public, and since then, it has been a trusted name in the SUV industry.
Unfortunately, the Chevy Suburban series is not entirely faultless, and some released models like the 2007 and 2004 models are pretty problematic due to several engine, A/C, brakes, and interior concerns.
Read the following article to learn more about these Suburban SUVs and wisely decide whether you should purchase one of them or not.
Chevrolet Suburban Years to Avoid: (With Reasons)
Since 1935, Chevrolet has been continuously modifying the initial style, design, and structural configuration of the Suburban series to ensure better built-in features, performance, and drivability in every new generation of Suburban models.
Unfortunately, the manufacturer failed to keep the same quality in all Suburban series released models.
As a result, some models came up with distinct issues like excess oil consumption, A/C failure, trouble with brakes and steering control, and transmission failure which potentially causes several other related problems.
Thus, if you are looking for a used Suburban model, avoid the following released years:
- 1999 Suburban
- 2003 Suburban
- 2004 Suburban
- 2005 Suburban
- 2007 Suburban
- 2008 Suburban

Most Common Problems of Chevrolet Suburban:
Let’s discover the most common Suburban problems that makes some of its released models worth avoiding-
1. Engine Failure
Minor engine problems are commonly occurring in almost all Suburban SUVs, but issues get noticeable and especially severe in 2007 and 2008 Suburban users.
Carcomplaint.com claims that thousands of Chevrolet Suburban owners had to fill up their vehicle engines with a new quart of oil after each 500 to 1000 miles of operation.
Reports even claim that most major engine problem occurs when the vehicle reaches around 76,000 miles, and the minimum servicing cost stays around $4,100.
The same report also claims that oil consumption is out of control in 2007 models, which feature the aluminum block engines with Active Fuel Management or AFM.
Mainly this issue has been occurring due to an uncovered AFM valve on those models, and people can get the problem fixed under warranty.
But unfortunately, this fix does not work for all 2007 models either, and in some cases, General Motors even recommended consumers replace the entire engine with a new one.
2. Brakes Failure
According to Carcomplaints.com and NHTSA both reports, several brakes issues have been identified in Suburban’s 2003, 2004, and 2015 released models.
Reports claim that most of those particular year’s suburban users encountered issues such as brakes not working properly or the excess brake lines corrosion causing the fluid to leak, rusted brakes, brakes prematurely wearing off, traction controlling system malfunction, or faulty Abs.
Even the Carproper.com website’s report states that some Suburban model brakes are difficult to hold or control and prone to failure, which is an alarming concern since brakes failure can eventually lead to encounter crashes if not fixed on time.
The same Carproper.com report also claims that problematic power brakes can make handling the steering hard and if somehow the vehicle tires failed to respond accurately, this can potentially lead to a severe accident.
3. A/C Malfunctioning
A/C malfunctioning or complete failure issues are commonly noticed on Suburban 2004, 2005, and 2015 released models.
According to Carcomplaints.com, consumers complained of encountering symptoms such as A/C compressor clutch failure, the air conditioner blowing hot air on the side (particularly the passenger side), A/C only blowing hot air, failed fan blower motor, or A/C erratically stopping working.
But one of the most common problems regarding some Suburban models is the A/C to only blow warm or hot air due to the A/C condenser leaking issue, and the main reason behind this commotion is frozen water vapor.
