The 2.2 Cavaliers with the oil filter on the back of the engine and when you finally get your hand down in there just right and get it off, it spills oil all over your exhaust that you have to smell burn off for the next few days.

Ah the good ol’ “No BUS” message. Or the craziness that can ensue from a battery that’s “mostly” okay, or CTM failures!

This describes the blend door actuator in Crown Vics. It's a cheap little $30 part that always breaks, with a 6-hour labor charge just to replace it. Every winter I commute an hour each direction with no heater because of this stupid design. The heater works GREAT, but the actuator died while on A/C. At least it's only a Phoenix winter, but still, driving in the 30's and 40's with no heat isn't what I call fun...

Chevy Traverse/Buick Enclave/GMC Acadia 3.6 V6 oil changes make my head spin. Extremely cramped engine bays with oil filters crammed under the exhaust manifold, and that area you get your hand in is also surrounded in hot AC lines. No time to wait for it to cool down in a shop, especially during summer. The best way to do it fast is to get a giant shop towel over my arm and get my oil filter wrench in there without dropping it. Taking the oil filter off spills oil all over the subframe, so time is also wasted cleaning it even with a drain pan underneath. You'd be lucky if the shop you take yours to even bothers to change out the pil filter. I go through it because I wanna do an honest job.

2006 Mazdaspeed 6 apparently had faulty shifter cable ends (transmission end) from the factory. Mine kept popping off the transmission during the 1-2 shift. I could limp somewhere in 2nd gear and re-connect, but it was just dangerous to leave that way.

What I would've thought to be a simple replacement turned out to require the ENTIRE dashboard removed. The dealership said U.S.-made Mazda 6 wasn't plagued with this replacement method.

+1 on the Ford water pump. Plus the headlights that are nearly useless on my 2014 Taurus.

When Blue Bird builds school buses, they run the interior wiring and THEN paint the whole interior white. So all of the interior wiring is painted. Makes tracing circuits an intolerable nightmare.

Crown Victoria, Mercury Grand Marquis and Marauder rear window regulators. Mounted with rivets. Also window glass is riveted to the lift plate. Very nerve wracking drilling rivets out that mount glass. And metal chips everywhere. Then you have to find proper bolts, nuts, flat washers and lock washers to go back together with it all.

Replacement rivets & tooling is readily available for this type of work. Knocking out the center pin on the old rivets before drilling them makes it pretty easy!

Northstar, One of the easiest starters to replace as well.....It's the Toyota UZ V8 engines (Also under the intake) that are labor intensive.

The top bolt behind the solenoid on Ford 3 Bolt starters can be fun!

The Panthers are throwbacks, but Ford used rivets for window regulators for decades. I replaced the driver's one on the 1977 Cougar (the replacement came from a Torino)-pretty easy job, actually. Drilled out the rivets, installed the replacement with short bolts & nuts.

Just changed the oil on my mom's 2011 Honda Fit 1.5L. The oil fill hole is way too close to the cowl, in fact it is basically under the cowl, so it's very hard to get to. It also has a plastic screen about an inch inside the fill hole so the opening is not deep enough to allow most funnels to sit in the hole. I service several vehicles for family/friends of all makes, and this is the dumbest oil fill design I've seen. On the contrary, the drain plug and filter are super easy to get to and make for very little mess. crazy
