This Week’s Winners

On this edition of Fix of The Week: a stalled Toyota, a shorted brake lamp bulb socket in a Hyundai, and wobbly Nissan.

 

1999 Toyota Camry – Hoffman’s Garage

This vehicle didn’t have any trouble codes stored but it would randomly stall when coming to a stop. The customer said it was difficult to start and acted like it was flooded. We scanned and didn’t find any codes, so we test drove it and noticed it acting up after a while.   

I started the car after it sat overnight to monitor the coolant sensor voltage. It started out around 2 volts and was idling fine. The coolant sensor voltage spiked to 4.5 volts for a split second and the car almost stalled. I replaced the engine coolant sensor and performed another test-drive—all good.

 

2011 Hyundai Sonata – Accurate Autoworks

This vehicle had intermittent no throttle response when the throttle was reapplied after coming to a stop. I verified the concern and checked for fault codes but none returned. I monitored the engine data and that was fine. During testing, I noted the engine could be started and transmission could be shifted into gear without depressing the gas pedal. I also noted one brake lamp was inoperative.   

I inspected the brake lamp bulb, which was fine, but the socket was melted/shorted. The shorted brake lamp bulb socket was giving feedback to the computer, causing it to think the brakes were applied, which inhibited the throttle response. I replaced the brake lamp bulb socket/sub-harness assembly. The dealer did advise that the brake lamp bulb sockets commonly fail on this model.  

 

2012 Nissan Rogue – Discount Inspection & Brakes

This vehicle’s front end was shaking between 10-35 mph while accelerating after the driver-side front axle shaft was replaced with aftermarket parts, which still had a warranty. The vehicle still had a vibration, so we swapped out the aftermarket CV axle for an OE axle from the salvage yard. The wobble went away with the OE axle. 

After comparing both axles next to each other, found the side of the axle that goes into the transmission was about 1/4 inch shorter, causing it to not complete seat inside the transmission.
