By the end of this article, you will know exactly which configuration fits your driving style and how to keep it running in peak condition for years to come. Let’s dive into the nuts and bolts of the 2019 Impala lineup.
Understanding the 2019 chevrolet impala configurations: LS, LT, and Premier
The 2019 model year represents the penultimate year for the Impala, meaning Chevrolet had refined most of the mechanical “bugs” from earlier iterations. The three primary 2019 chevrolet impala configurations cater to different priorities, from fleet-focused utility to near-luxury cruising.
The LS trim serves as the entry point, primarily featuring the 2.5L four-cylinder engine and essential tech like the 8-inch touchscreen. It is a solid choice for those who prioritize fuel economy and want a simple, reliable daily driver without many electronic “extras” to break down.
Stepping up to the LT trim provides the most flexibility, as it allows you to choose between the two available engines. It adds creature comforts like dual-zone climate control and remote start, making it the “sweet spot” for most DIY enthusiasts and families.
The Premier trim is the flagship configuration, coming standard with the 3.6L V6 engine and a host of luxury upgrades. With leather seating, navigation, and advanced safety tech, it competes directly with entry-level luxury brands while maintaining Chevy’s manageable maintenance costs.
Comparing the LS and LT Base Models
While the LS and LT may look similar from a distance, the LT offers significantly more “package” options that affect the car’s electronics. For instance, the LT can be equipped with the Convenience Package, which adds heated seats and a heated steering wheel.
From a maintenance perspective, both trims use similar suspension components, making it easy to find replacement struts or control arms. However, the LT’s upgraded alloy wheels require different tire sizes than the basic LS steelies, something to note when shopping for rubber.
Engine and Drivetrain Specs: 2.5L Ecotec vs. 3.6L LFX V6
The heart of any configuration is the powertrain, and the 2019 Impala offers two very different driving experiences. The base 2.5L Ecotec four-cylinder produces 197 horsepower and features Start/Stop technology to save fuel at traffic lights.
While the 2.5L is adequate for city driving, many enthusiasts prefer the 3.6L LFX V6, which pumps out a robust 305 horsepower. This engine transforms the Impala into a highway cruiser that can merge effortlessly into fast-moving traffic without breaking a sweat.
Both engines are paired with a 6-speed automatic transmission, specifically the 6T70 or 6T45 series, depending on the engine torque. These transmissions are generally reliable, but they do benefit from regular fluid exchanges every 45,000 to 60,000 miles to prevent “shudder” issues.
Fuel Economy and Performance Trade-offs
The 2.5L engine is the winner for budget-conscious drivers, offering an EPA-estimated 22 mpg city and 29 mpg highway. It uses a high-pressure direct injection system, which means you should use a high-quality Top Tier fuel to prevent carbon buildup on the intake valves.
The 3.6L V6 is thirstier, averaging about 19 mpg city and 28 mpg highway, but the performance gain is substantial. If you plan on carrying a full load of passengers or frequently driving through hilly terrain, the V6 is the superior choice for longevity as it won’t be under constant strain.
Interior Comfort and Tech Across All 2019 Chevrolet Impala Configurations
Chevrolet focused heavily on “quiet-tuning” the interior of the 2019 Impala, regardless of the trim level you choose. Every version features active noise cancellation (on the 4-cylinder) and thick acoustic glass to keep the cabin serene during long road trips.
The infotainment system is a highlight across all 2019 chevrolet impala configurations, featuring standard Apple CarPlay and Android Auto. This is a huge win for DIYers because it means you don’t need to perform expensive head-unit swaps to get modern navigation and music streaming.
In the Premier trim, you get the Bose Centerpoint Surround Sound system, which includes 11 speakers. If you are a rider or off-roader used to rugged setups, the plush leather and ventilated seats in the Premier will feel like a mobile lounge after a long day in the dirt.
Storage and Utility for Road Trippers
The Impala boasts a massive 18.8 cubic feet of trunk space, which is enough to fit camping gear, tools, or multiple sets of golf clubs. The rear seats also fold down in a 60/40 split, allowing you to slide in longer items like lumber or fishing rods.
One “pro tip” for owners is to check the hidden storage compartment behind the motorized touchscreen. By pressing a button, the screen slides up to reveal a felt-lined cubby with a USB port—perfect for hiding your wallet or phone while at the trailhead.
Maintenance and Reliability: What DIYers Need to Know
Maintaining the 2019 Impala is straightforward, provided you follow the Dexos1 Gen 2 oil specification. For both engines, I recommend using a high-quality full synthetic 5W-30 oil to protect the timing chains and turbo-adjacent components.
The braking system uses a standard disc-on-disc setup that is very accessible for a weekend mechanic. When replacing pads, ensure you use a silicone-based brake lubricant on the caliper slide pins to prevent uneven wear, a common issue on heavier sedans.
Accessing the cabin air filter is one of the easiest DIY tasks on this car; it is located behind the glovebox and can be swapped in under five minutes. Keeping this clean is vital for maintaining the performance of the dual-zone climate control system in the LT and Premier trims.
Essential Tools for Impala Maintenance
- 10mm Socket: The “universal” size needed for the battery terminals and various engine covers.
- T15 Torx Driver: Required for many interior trim pieces and the cabin air filter housing.
- Floor Jack and Stands: Essential for oil changes, as the Impala has a relatively low ground clearance.
- OBD-II Scanner: Useful for diagnosing the “StabiliTrak” warnings that occasionally pop up due to wheel speed sensor debris.
Common Problems and Troubleshooting for the 10th Gen Impala
No vehicle is perfect, and the 2019 Impala has a few known quirks that owners should watch for. One common issue is the shifter assembly microswitch, which can fail and prevent the car from recognizing it is in “Park,” leading to a battery drain.
Another area to monitor is the cooling system, specifically on the V6 models. The plastic coolant crossover pipes can become brittle over time due to heat cycles; replacing these with updated parts before they leak can save you from a roadside breakdown.
If you experience a “vibration” while braking, it is often not the rotors themselves but rather worn suspension bushings. The Impala’s heavy front end puts a lot of stress on the lower control arm bushings, so inspect them every time you have the wheels off for a rotation.
Handling “Service StabiliTrak” Messages
If your dashboard lights up with a StabiliTrak warning, don’t panic immediately. Often, this is caused by a dirty ABS tone ring or a loose wheel speed sensor wire. Cleaning the sensors with a bit of electrical contact cleaner often solves the problem without needing expensive parts.
Performance Upgrades and Customization Tips
While the Impala isn’t a sports car, there are several ways to sharpen the handling of various 2019 chevrolet impala configurations. Upgrading to polyurethane bushings in the front suspension can significantly reduce “nose dive” during hard braking and improve steering feel.
For V6 owners, a high-flow cold air intake can provide a slightly more aggressive engine note and a modest boost in throttle response. Just be sure to choose a dry-media filter to avoid fouling the Mass Air Flow (MAF) sensor with oil droplets.
If you use your Impala for long-distance travel, consider upgrading the factory tires to a high-performance all-season variant. Tires like the Michelin Defender or Continental PureContact offer better wet-weather grip and a quieter ride than the OEM rubber found on the LS and LT trims.
Safety Ratings and Driver Assistance Features
The 2019 Impala received high marks from the IIHS and NHTSA, making it a top choice for safety-conscious buyers. The Premier trim offers the most advanced features, including Forward Collision Alert, Lane Departure Warning, and Side Blind Zone Alert.
For DIYers, it is important to note that these sensors are often located behind the bumpers and near the rearview mirror. If you are performing bodywork or replacing a windshield, these systems may require re-calibration by a professional to ensure the emergency braking functions correctly.
Frequently Asked Questions About 2019 Chevrolet Impala Configurations
Which 2019 Impala configuration is the most reliable?
The LT trim with the 3.6L V6 is widely considered the most reliable. The V6 engine is a “workhorse” used across many GM platforms, and the LT trim avoids some of the more complex electronic suspension components found in other luxury sedans.
Does the 2019 Chevrolet Impala have All-Wheel Drive (AWD)?
No, all 2019 Impala configurations are strictly Front-Wheel Drive (FWD). If you need AWD for snowy conditions, you would need to look at the Buick LaCrosse or Cadillac XTS, which share the same platform but offer AWD options.
Can I upgrade an LS trim to have the V6 engine?
While technically possible, it is not cost-effective. The V6 requires a different transmission, wiring harness, and cooling system. It is much cheaper to buy an LT or Premier trim that already has the V6 configuration from the factory.
What is the “Midnight Edition” configuration?
The Midnight Edition is an appearance package available on the LT and Premier trims. It adds 19-inch black-painted wheels, a blacked-out grille, and black bowtie emblems, giving the car a much more aggressive, “stealth” look.
Final Thoughts on the 2019 Impala
