Cars Mechanics Say to Run From

Mazda rx8

Mazda rx8

Mechanics commonly advise against purchasing the Mazda RX8 due to its notorious mechanical issues. While the rotary engine design is partly to blame, the specific engine configuration exacerbates reliability concerns. Unlike its predecessor, the RX7, which can endure upwards of 200,000 miles with proper maintenance, the RX8 suffers from an inadequate oil delivery system.

 

The redesign aimed to reduce emissions, typical for rotary engines that burn oil during operation. However, this modification proved ineffective and led to lubrication problems within the combustion chamber. As a result, the RX8 frequently experiences engine failures and other mechanical malfunctions, making it a risky investment for prospective buyers.

GMC Sierra

Mechanics commonly discourage purchasing GMC vehicles, particularly the Sierra model, citing persistent transmission and electrical problems. These issues have plagued GMC vehicles for years, leading to frequent breakdowns, which is particularly inconvenient during nighttime driving on highways. Furthermore, General Motors' quality control has been questionable, especially with models featuring the 3300, 3400, and 3900 V6 engines, which are deemed unreliable and poorly constructed. Despite improvements in recent years, skepticism towards American-made cars remains prevalent among consumers.

For instance, the 2015 GMC Sierra received low marks for safety due to the following:

  • Low reliability
  • Inadequate headlight patterns
  • Erratics A/C performance
  • Engine power loss
