Chirping/squeaking/squealing noise when stepping on the gas pedal

Topic starter

Hello I just picked up a 2008 Lexus RX350 with about 74k miles on it. From the get go, after a PPI, I had the following parts replaced by the dealer:

1. Power steering pump and hose

2. alternator

3. pulley

4. tensioner

5. serpentine belt

6. water pump

7. radiator

8. thermostat 

 

However, I’m now hearing a squealing/squeaking/chirping noise that’s audible ONLY when I’m stepping on the gas pedal and the car is running. But when I put it in neutral and step on the gas, there’s no noise.

 

Any idea what could be causing this? Thanks in advance.

in neutral and step on the gas, there’s no noise.

that means it's not related to ANY of the parts replaced by the dealer. Sounds like they took you to the cleaners , which is why we recommend you stay away from there.

The problem will be in the driveline, such as wheel bearings. Please ask around for a dependable independent mechanic.
