Audio problem: Throughout the series the engine sound from Walt's Pontiac Aztek sounds like a 4-cylinder engine, but the Aztek was only ever available with a V6.
Other mistake: The configuration of the front side of the house does not match the configuration from the inside. The outside view looking at the house from the street indicates (1) there are no rooms to the right of the garage (when inside there are rooms on the side of the garage). Also when looking at house from street side, to the left of the front door the house comes forward. When inside, (at least in episode 13, season 3) the inside of the house does not extend forward towards the street.
Plot hole: It doesn't make much sense that Marie had to ask Walt and Skyler to pay Hank's medical bills. They both make good money! Hank is a DEA agent and she is some kind of medical professional. There is no reason in the world that this couple cannot afford this. Same thing with Walt.
Suggested correction: Their insurance doesn't cover the bills; without that, bills can stack up quickly. You need a lot higher salary than a DEA agent to cover it, even if he got as high as 120,000 USD a year. Marie can't work as she is taking care of her husband.
Continuity mistake: When the black and white intro of the plane crash plays, it shows Walt's truck completely destroyed, with every single window busted into pieces as if a meteor hit it. But yet he drives it after the plane crash, and only the windshield is cracked.
Suggested correction: If you research "The Breaking Bad House" you will see that the house used was filmed both inside and out, so this error couldn't have happened.
The garage is shown to have an interior door. Walt comes through it when he is showing baby Holly the money hidden behind the insulation. However, the is no corresponding door inside the house. The interior house scenes, at least most of them, must be a set.

Wrong, the interior of the house is a set, and there are numerous inconsistencies that show this. One, being the location of the fireplace, and the other being an interior door to access the garage.
