> [@TheWonderful90s](#): > > Not using any anti seize lubricant on exterior bolts. Because manufacturers don’t WANT the bolts to fall out and the bolts are typically zinc plated for corrosion protection > [@TheWonderful90s](#): > > The growing use of plastics everywhere on the interior. What would you prefer? Steel (so impacts will injure you)? Leather (that is still backed by plastics)? Wood (so the impacts can splinter and impale you)? > [@TheWonderful90s](#): > > Plastic parts that clip in to place without the use of fasteners. So you don’t SEE any fasteners. Fasteners are considered ugly. > [@TheWonderful90s](#): > > Small brake disks that don’t have any extra material left to be turned and reused. All brake rotors have some extra material. Shops don’t turn them because it is more cost effective to replace them because they are cheap to buy new. > [@TheWonderful90s](#): > > Leaving the insides of frames and rocker panels untreated for corrosion. No manufacturer does this anymore and haven’t for 40+ years. Rockers and frames are galvanized, sometimes on both sides, and many are hot dipped in a paint bath to protect them. > [@TheWonderful90s](#): > > Lower quality rubber used on suspension components Rubber quality today is FAR better than stuff used prior to the 1980s and lasts far longer. The same can be said of plastics. > [@TheWonderful90s](#): > > Setting the battery charge voltage at 14.4 with no temperature compensation nor adjustment. The charging is controlled by the ECU which also has temperature inputs from outside, the intake air, coolant and more. Batteries die in the south because engine compartments are FULL and therefore very HOT. My trunk mounted battery lasted 7 years on my Florida car. > [@TheWonderful90s](#): > > Not putting an hours meter in the vehicle My GM truck has one. > [@TheWonderful90s](#): > > Skipping the CD player too! The CD is a dead player in the music business as are cassettes, 8-tracks and 45 records. Sorry, that is just the way it is Grandpa! 😃 > [@TheWonderful90s](#): > > Switching to a dead end fuel system Huh? My single-line pressure system has a pressure measurement port plus the quick-connect lines pop off easily. Just how many times has this affected you? > [@TheWonderful90s](#): > > Not using a high reliability engine main seal. When it starts leaking the cost to fix it can makes it not worth it. Manufacturers use the best they can buy and my experience with them is far better lately than my 60s ad 70s cars. The transmission must come to replace a rear main and that will be expensive no matter what you do. > [@TheWonderful90s](#): > > Non tow-able automatic transmissions. The old ones had dual oil pumps and could be towed with wheels on the ground. Nope. Very rare to have a towable automatic. > [@TheWonderful90s](#): > > No transmission oil temperature warning. I have one in 2 of my 3 cars. That’s a majority. > [@TheWonderful90s](#): > > No coolant loss warning on most vehicles. Volvo has it. So do 2 of my 3 cars… that’s another majority! > [@TheWonderful90s](#): > > No fluid filter in automatic transmissions. Every transmission has a filler port of some sort. If you are bemoaning the lack of a dipstick, that is a separate argument. > [@TheWonderful90s](#): > > No debris screen to save the engine from turbo debris in case of a blown turbo. So what about the oil pickup screen? And what about the oil filter itself? BOTH are between the turbo outlet which goes straight to the pan and the oil pressure galleries. > [@TheWonderful90s](#): > > instead of traditional separate vacuum fluorescent displays Again, get with it Grandpa. > [@TheWonderful90s](#): > > Cheap window switches in doors. There is no dust seal or sweeping action to keep the contacts clean. My 18 year old truck’s switches work fine… and they’ve been exposed to lots of dirt. --- _[View the full topic](https://community.cartalk.com/t/manufacturers-design-shortcuts/184046)._
