Subscription Cars, CAN Bus Theft & the Real Cost of Modern Repairs

Watch Now

This week on the C&C Auto Show, the crew tackled the fast-changing world of modern vehicles — from subscription-based heated seats and remote vehicle shutdowns to the growing concerns over CAN bus car thefts and ADAS calibration after suspension modifications.

They also broke down what’s happening with the Ford F-150 Lightning, why EV resale values are raising eyebrows, and how new refrigerant regulations are driving up A/C repair costs. Add in real-world caller questions about stability control warnings, battery testing in cold weather, tire cupping on a Toyota Camry, and whether police should be able to remotely stop a vehicle — and you’ve got a packed show full of practical advice and spirited debate.

If you want clarity on today’s automotive technology, repair costs, and ownership trends, this episode delivers straight talk from the shop floor.

Questions and Answers

Key takeaways from this episode covering vehicle subscriptions, theft vulnerabilities, EV trends, A/C repairs, and real-world diagnostic advice.

How can modifying a lifted or lowered vehicle affect ADAS systems?

Changing ride height, bumpers, or suspension geometry can alter how radar and camera systems read the road. That may affect automatic emergency braking, lane assist, or adaptive cruise control. In many cases, recalibration is required to ensure the systems operate safely.

Can police remotely shut down a vehicle during a pursuit?

In some cases, law enforcement can contact the manufacturer to request a remote slowdown or shutdown of a connected vehicle. The feature is designed to reduce risk during high-speed chases. However, it also raises privacy and control concerns among drivers.

What is CAN bus headlight hacking and how are cars stolen this way?

Some thieves access a vehicle’s CAN network through wiring behind the headlight or other exposed components. By injecting signals, they can unlock doors or program a key. Manufacturers are now adding security updates and firewall protections to reduce this vulnerability.

Are subscription features like heated seats a good idea?

Subscription-based features allow owners to activate options through software, but many drivers question paying ongoing fees for hardware already installed in the vehicle. The debate centers on ownership rights, long-term cost, and manufacturer control over vehicle functions.

Is the Ford F-150 Lightning a risky investment right now?

The show discussed concerns about resale value and shifting EV demand. When production slows or models are discontinued, used values can drop quickly. Buyers should consider long-term support, infrastructure, and market demand before investing.

Why are A/C repairs more expensive with R-1234yf refrigerant?

R-1234yf refrigerant costs significantly more than older R-134a systems. Proper leak detection and recovery procedures are also more involved. Because refrigerant is expensive and regulated, accurate diagnosis is critical before recharging the system.

Why shouldn’t you use stop-leak products in your A/C system?

Stop-leak additives can clog internal components and damage professional recovery machines. They often create larger repair bills later. Proper leak detection and component replacement is the safer long-term solution.

Why does a stability control warning sometimes disable cruise control?

When a fault is detected in traction or stability control systems, the vehicle may disable cruise control and other features as a safety precaution. In some cases, sensor or injector wiring issues can also trigger reduced power conditions.

How long should a car battery last and when should it be tested?

Traditional flooded batteries typically last four to five years, while AGM batteries may last longer. Cold weather puts extra strain on aging batteries. A proper load test can help determine remaining strength and prevent unexpected failure.

What causes tire cupping and vibration at highway speeds?

Cupping can result from worn struts, suspension components, or improper alignment. Even if struts are not leaking, they may be weak over time. A four-wheel alignment and inspection can help protect new tires and improve ride quality.
