The TikTok video highlights a crucial piece of information from the 2017 Toyota Highlander owner’s manual – these vehicles allow 384,000 restarts before the starter motor and relays necessitate replacement. This startling revelation brings attention to a previously unnoticed facet of auto start/stop systems.

Once the designated number of restarts is reached, the check engine light illuminates, signaling the need for a visit to a Toyota dealership. At the dealership, a service technician will replace the starter motor and relays and reset the counter through specialized software.

Considering the average ownership span of eight years, this equates to approximately 131 restarts per day. This statistic raises a red flag for consumers exploring the used car market, as the potential looming cost of a starter motor replacement becomes a significant consideration.

As car owners evaluate the pros and cons of the auto start/stop feature, the longevity of the starter motor takes center stage in decision-making.

The auto start/stop system, despite its fuel efficiency benefits, has garnered criticism from car owners. The annoying shuddering sensation when the power unit automatically turns on and off, especially in stop-and-go traffic, can be a source of frustration. Additionally

the delay in firing up the engine while sitting in traffic can impede a swift getaway. These annoyances contribute to the reluctance of some drivers to embrace the auto start/stop feature.

In certain scenarios, when the engine shuts off automatically, accessories such as dashcams may also go offline. The air conditioning system ceases to function, which can be particularly bothersome during hot summer days. Adding to the inconvenience, the auto start/stop system automatically activates with each car start, necessitating drivers to manually disable it each time to avoid interruptions.

Despite these challenges, the auto start/stop system is here to stay. The fuel efficiency and emission benefits it offers align with stringent standards set by the Environmental Protection Agency (EPA). Automakers continue to integrate this feature into their designs, ensuring compliance with environmental regulations and contributing to the global effort to reduce emissions.

In conclusion, while the auto start/stop system brings undeniable advantages in fuel efficiency and emissions reduction, Toyota owners must be aware of its impact on the starter motor’s lifespan. The prescribed restart limit of 384,000 serves as a reminder for meticulous vehicle maintenance and prompts prospective used car buyers to weigh the potential cost of starter motor replacements.

As the automotive industry evolves, adapting to environmentally conscious practices, the auto start/stop system remains a key player, challenging drivers to find a balance between fuel efficiency and the longevity of essential components.
