Franklynn Auto was extremely fast and professional. Did not try to upsell me and provided exactly what I needed. When an at home DIY transmission pan replacement and fluid replacement went wrong, I decided to tow to Franklynn’s due to the amazing amount of reviews. I’m a cheapo and love to do all of my own vehicle maintaining. One bolt sheared off and Franklynn’s was able to help fix my mistake. While it may have been just good timing, I was able to get in the next morning and had my truck back within 8 hours. Thank you so much for your courteous phone calls on updates and findings. The work was excellent and mechanics informed me of everything they did as well. Thank you thank you thank you for getting my daily driver to me back quickly!!!Posted on Google![]()

I think, one of the best auto shop repair experiences I ever had. I went to a dealer who charged $250 for diagnostics for a seatbelt that was on back order with no clue when the repalcement would be available and a liftgate motor they said needed to be replaced. I declined. I know, my mistake to begin with. I took it to Franklynn and talked to Steve. On the same day, Steve found a replacement seatbelt a shade off color, but could get it installed soon for less than half the price of the dealer. I know, dealers must use OEM parts. For the liftgate motor, the technician found a technical service bulletin that described re programming a computer module. That fixed the problem for less than 20% of the dealer estimate. As for honesty, the technician drove the vehicle and thought he heard a noise in the rear suspension. I authorized investigation and Steve called back to say it was a can under a seat that was making the noise. They could have come up with the doohickey connected to the thingamajig that needed replacement. They didn't. They are professional, efficient, honest, and fairly priced. I will be back and highly recommend this shop to my friends and family. The address is South Broadway, but they actually front Southpark Plaza just north of Southpark Dr just north of Goodwill.Posted on Google![]()

I am a new customer to Franklynn Automotive as of October 2026 on the referral of my neighbor, as my longtime auto shop closed their doors. My first visit was for a routine oil change for my 2013 Honda CRV. Upon further and thorough inspection, they alerted me to the immediate need for rear brakes/rotors. They were able to squeeze me in a few days later and complete the job. I was worried that I would be unable to find a reliable and honest comparative auto shop but I have found it in Franklynn! Steve and Jodie at the front end are so helpful, friendly and knowledgeable. Good service is still a thing and I couldn’t be happier!Posted on Google![]()

Steve, as usual, was very organized and ready for my appointment at 8:00 AM Monday to replace my brakes. He informed me of the changes on brakes pad composition and if I experienced any noise issues to come back and they would recheck everything. I highly recommend Franklin Automotive for all your auto service needs. Rick GerberPosted on Google![]()

This is a gem of automotive specialist from Steve Waggle on the front desk to each technician in the shop. I wish I give them all credit. For myself my focus on brake repair that has taken over a year to completely figure out. Twice at Dealer in 2 states. Towing and feeling safe since I had a failed brake master cylinder that brake upgrade was not completed on 2015 Dodge Truck. Franklyn Automotive took notes, listened, drove vehicle at my recommendation to simulate truck not being to stop. A nd Voila "they figured it out as a failed Power Braker Booster". They also did all the items on my list from premium oil changes, repair faulty wiring in Topper, tire rotation, etc, etc. Please give these folks your business. You will not be sorry. Glenn

Frequently Asked Questions:
Common warning signs include knocking or tapping noises, loss of power, rough idling, stalling, difficult starting, excessive oil consumption, fluid leaks or unusual exhaust smoke. An illuminated check-engine, oil-pressure or temperature warning light also requires attention. These symptoms can originate from the engine or from related fuel, ignition, cooling, exhaust or electrical systems, so diagnosis should occur before repairs are recommended.
The process depends on the vehicle and symptoms. It may include retrieving diagnostic trouble codes, reviewing live vehicle data, checking fluid levels and condition, inspecting for leaks, and testing ignition, fuel, compression or cooling-system operation. Intermittent concerns may require additional testing or a road test. A computer scan supplies useful clues, but it is not a complete engine diagnosis by itself.
Yes, especially if the sound is new, loud or becomes more frequent. Possible causes include low oil level, inadequate oil pressure, ignition-related detonation, worn valvetrain parts or internal bearing damage. Some fuel injectors and other components normally produce light ticking sounds, so the noise should be evaluated before assuming the engine has major internal damage. If the oil-pressure light accompanies the noise, shut off the engine as soon as it is safe.
Reduced power may result from ignition misfires, restricted airflow, fuel-delivery problems, exhaust restrictions, sensor faults, overheating or mechanical wear. Some vehicles intentionally limit power to protect the engine or transmission after detecting a serious fault. Because replacing individual parts without testing can become expensive quickly, the vehicle’s codes, operating data and mechanical condition should be evaluated first.
Oil loss can occur through an external leak or internal consumption. External leaks may develop around gaskets, seals, the oil pan, filter or other components. Internal consumption may involve piston rings, valve seals, the crankcase-ventilation system or turbocharger when equipped. Some engines consume a limited amount of oil between services, but a sudden increase, visible smoke or repeatedly low oil level should be investigated.
Blue or gray smoke may indicate that engine oil is entering the combustion process. Persistent white smoke after the engine is warm may suggest coolant entering the engine, while black smoke can indicate an overly rich fuel mixture. Brief vapor during cold weather can be normal condensation. Smoke color alone cannot confirm the cause, but heavy smoke, overheating or rapid fluid loss requires immediate attention.
Pull over safely and shut off the engine. Continuing to drive can damage the cylinder head, head gasket, pistons or engine block. Never open a radiator or pressurized coolant cap while the engine is hot. Overheating may be caused by low coolant, a leak, faulty thermostat, damaged cooling fan, failing water pump or another problem. AAA advises shutting the engine off when the temperature gauge reaches the hot zone.
The best option depends on the diagnosis, extent of damage, vehicle value, mileage, overall condition, parts availability, and expected ownership period. A targeted repair may be appropriate when damage is limited to a specific component. Extensive internal damage may make rebuilding or installing a replacement engine more practical. The estimate should explain what is included, the source and condition of the engine, applicable warranty coverage, and any related components that need attention.
Stop driving when it is safe if the oil-pressure or overheating warning appears, the check-engine light flashes, the engine begins knocking loudly, heavy smoke develops or the vehicle loses substantial power. A major oil, fuel or coolant leak also warrants stopping. Continuing to operate the vehicle under these conditions can increase damage or create a safety risk. AAA identifies thick white smoke and severe overheating symptoms as reasons to pull over and arrange assistance.

If the engine is making unusual noises, losing power, leaking fluid or displaying a warning light, schedule an appointment so the cause can be identified before a repair plan is recommended.
