A Buyer's Guide to the 2012 Buick Regal eAssist

Although a lot changed about the Buick Regal in 2012, the addition of a hybrid model was definitely the biggest head turner. Whether you want to do your part for the environment or simply save at the pump, this lithium-ion-battery-assisted sedan is one of the best options out there.

Key Features

Obviously, the most important feature is under the hood of the 2012 Buick Regal eAssist. That’s where you’ll find the lithium-ion battery pack attached to an electric motor. Together, these components assist the 2.4-liter engine of this mid-size sedan in covering more distance with less gas. The E85-compatible engine will also help you save more money at the pump. This model features Buick’s IntelliLink Bluetooth infotainment system as well.

Changes for 2012

Everything about the 2012 Buick Regal eAssist is new. This is the first Regal to feature this type of hybrid battery. What We Like

Clearly, the eAssist engine on this regal is easy to like. It’s good for an extra 15 horsepower, which you can actually feel during acceleration. You also benefit from 26 mpg when driving in the city. That will turn into 37 on the highway, which is really impressive considering how large this sedan is.

There is also regenerative braking, fuel cut-off, engine stop and start, underbody panels, grille louvers that will actually close during acceleration and low-rolling resistance tires.

What Concerns Us

While the 2012 Buick Regal eAssist is affordable given all it brings to the table, there are a ton of extra features you could add that would significantly increase the price.

The exterior of this Regal definitely went in a different direction than in decades past, which might rub some people the wrong way. It also feels like a European car when you’re driving it. Again, this won’t be to everyone’s liking.

Available Models

There is only version of the Buick Regal eAssist.

Major Recalls

Buick has issued recalls for 2012 Regals four times, which would have included some eAssist models.

There were two in 2012. Once it was because of parking lamps that wouldn’t activate due to an error in the car’s software. The other recall was issued when it was discovered that turn signals could burn out without the driver becoming aware.

In 2013, a recall was announced because some Regals’ batteries were dying after the generator control module (GCM) would malfunction. The last one was in 2014 because the front seats could unexpectedly drop to the lowest position due to a problem with the bolts used.

Common Issues

You may have to get used to the feel of the ion-lithium battery coming to life and adjusting to how that affects your acceleration, but that’s about it.

Chevrolet Impala V6-3.6L - Pre-purchase Car Inspection - Lansdale, Pennsylvania
Shawn was prompt, professional, and delivered the promised service as expected. This was a used vehicle pre-purchase inspection. Shawn also had to drive to multiple locations to perform the inspection, as the address listed that I provided him with was not accurate, but he still made it to the correct location within his time window and completed the inspection.

Shawn was very prompt in communicating with me and was good at helping me decide whether to purchase a used car. He help me avoid a car with a repaired rusted frame that could be a danger to my family's safety since we were planning on using the car to tow a travel trailer!

Luis did a thorough pre-purchase inspection for me, and found several major issues that made me pass on buying the car. Had I purchased the car, I almost certainly would have ended up paying thousands in repairs down the road. Thanks Luis!

He did a pre-purchase inspection for me. He was knowledgeable and fast, and knew what he was looking for. I really appreciate all the pictures and documentation he took of the state of the car before purchase. He noted potential issues with the car that I wouldn't have been able to notice. Would recommend.

I trust Robert. He gave me a list and we will take care of it the week of June 29. I will know then that my vehicle is ready for the winter and is safe to drive. I look forward to getting things ready for another winter of careful driving.
