(#10) Out-Of-Warranty BMWs
From Redditor /u/innerearinfarction:
My mechanic tells me never to touch an out-of-warranty BMW.
He owns two, and says the electronic gremlins have driven him insane, and are virtually unfixable by a non-dealer mechanic. They require circuit board replacements, proprietary software readers, etc.

(#8) Any GM, Chrysler, Or Nissan
From Redditor /u/judgestorch:
Been a shade tree mechanic in the US for more than 40 years...
Nissan quality has fallen since their merger with Renault more than a decade ago. Worst auto transmissions in the industry now, made by JATCO.
Chrysler has never really recovered in quality since their K-car/minivan rebirth days of the 1980s. There is a reason they've faced bankruptcies and had subsequent mergers with Daimler and Fiat.
GM has shifted design and manufacturing overseas, mainly to Korea, for its passenger cars (which is an actual improvement from the crap they have been selling for decades). But the quality simply doesn't compare to Toyota or Honda. The same goes for Hyundai and Kia - mediocre quality at best.
Ford probably ranks third in quality, behind Toyota and Honda.
As cars have become more complicated to meet EPA and safety standards, reliability has dropped. There are miles of wiring, harness connectors, multiple computer control units, and countless sensors. It's almost impossible to make a car with high reliability and affordability at the same time, but the quality control at Toyota and Honda seems to outpace all others.

(#7) Mazda RX-8s
From Redditor /u/ldg25:
Son of a Mazda mechanic. If you live in the North, or anywhere it gets remotely cold, do not buy an RX-8.
It won't work three to four months out of the year, and will need constant, expensive care in the other months.

(#16) Ford Tempos And Contours
From Redditor /u/InferiousX:
Ford Tempo or the Ford Contour.
Notorious for transmission failures.

(#11) Brands Aren't As Important As Transmission/Engine Combinations
From Redditor /u/Sicknessindustries:
American automotive engineer here, mechanic before that.
Brands and models mean nothing. You need to go after or avoid specific engine or transmission combos. A same make and model year of a vehicle could have a 4-cylinder engine with great reliability, but a horrible 6-cylinder.
An example of this would be any 3.0L V6 in Toyota Trucks and SUVs from 1988-1995. They are gutless, inefficient, and eat head-gaskets, whereas the 4-cylinders from that era are bulletproof.
There are some really bad ones. Any full -ize Ford Superduty 6.0L Diesel has only four headbolts per cylinder like a gasoline engine, [so] the head gaskets blow anytime something small fails. GM full-size diesels use the Japanese engineered 6.6L Isuzu Duramax, which still commands high value.
Google is your friend. Find the engine and transmission model numbers and do your research before buying.

(#5) GMs With 3300, 3400, And 3900 V6 Engines
From Redditor /u/anail1994:
Actual mechanic here.
Buy nothing from General Motors with the 3300, 3400, or 3900 V6 engines in them. They are unreliable trash and come from the "high value" platform. That means cheap, and not for you - cheap for General Motors.
Poorly made parts all the way through and really awful engineering. The 3800 V6, on the other hand, is an amazing motor with only a few minor problems.
