Satisfaction Rating1/5
A girl took her 2000 Honda Civic to Monroe Muffler/Brake at 4872 Transit Road in Depew, NY, on 10/11/11 because the exhaust was loud and the car was running poorly. She was told that the car needed a new catalytic converter. Monro replaced the catalytic converter, the Y-pipe and O2 sensors. They also replaced ball joints on both sides, even though the car was driven less than 1000 miles since a safety inspection, performed in August (hmm, youd think that would've been mentioned by the mechanic who performed the inspection). Add an alignment, and the total of that work came to $2040.
About one week later, the cars check engine light went on, the speedometer was stuck at zero, and the car would not shift properly. The girl took the car back to Monroe, as they had worked on it so recently. Monro somehow made the diagnosis that the Linear and Control Solenoids in the transmission were faulty and they replaced them, at a cost of $1060.
One week later, the same problem reoccurred. Monro initially suspected that the new solenoids they installed were defective, but after further analysis, they concluded that the problem was due to the Electrical Load Detector. It is not clear what Monro did to correct this problem, as they did not charge for the service and no receipt was provided. At this point, however, one has to wonder if this problem (the same problem seen the previous week) was caused by the ELD, was it necessary to replace the solenoids?
Ten days later, the same problem occurred, again. This time, a mechanically-inclined friend examined the car. Suspecting an electrical short, he examined the wiring and connections on the engine and under the car, including the wiring to the solenoids the oxygen sensors that were installed by Monroe during the original exhaust work. Sure enough, the insulation on one of the wires to the O2 sensor in the catalytic converter was worn away from rubbing on the chassis of the car. The wire was grounding out, causing a short circuit (and the symptoms with the ELD and transmission). It seems many other people have experienced a similar problem with their Hondas -- see this thread:
\Having made this discovery, the girl and friend took the car back to Monro and confronted the manager. The friend showed the bare wire to the manager and explained that it, not the solenoids, were the cause of the problem, all along. The manager then asked the friend If you know so much, why didn't you fix the car? The girl and friend left the car with Monro to make the repair. Two hours later, the manager reported that the car was fixed. He stated that the connector to the solenoids was loose an outright lie, as the friend had checked that connection before taking the car back to Monro.
Conclusion: Monroe's work on the exhaust system resulted in a shorting wire, which caused the other symptoms seen with the transmission, ELD, and check engine light. Monro then misdiagnosed the problem and charged the girl over $1000 for parts she didn't need (which should be obvious, as the same problem kept coming back). Rather than admit to the mistake, the manager lied about the loose connector.
